237Info Title:
Roosevelt Tunnel Extension Plans Negotiations looking to extension of the Roosevelt deep-drainage tunnel, some 3000 ft. distant from the Golden Cycle shaft, are under way, but no agreement has as yet been reached. The Vindicator Consolidated company is extending a lateral north-west from the 19th level of the Golden Cycle shaft, corresponding to what will be the 20th level of the Vindicator No. 2. The objective is the present terminal point of the Roosevelt deep-drainage tunnel.
The extension of the tunnel rests with other companies owning property in the Bull Hill area, who are expected to contribute to the general cost, estimated at $80,000. The Vindicator company, however, will extend the deep lateral to its end-line at its own expense, and at the present time is draining the Bull Hill area, and it feels that property owners should contribute toward the tunnel extension through other than Vindicator holdings.

Roosevelt Tunnel Facts The Roosevelt tunnel may now be considered completed, as work has ceased with the heading in the centre of the Hawkeye claim of the Portland company. The total length of the tunnel from portal to breast is 24,355 ft., or 4.6 miles, and it is one of the longest in the United States.
The Roosevelt tunnel has taken 11 years to drive and its cost has been $812,000. This sum includes sinking of an intermediate shaft 700 ft., and a raise of 160 ft. to connect with the Elkton main shaft, through which the tunnel is now operated. The average cost has been $33.30 per foot.
The saving in pumping costs alone is conservatively estimated at $3,000,000.
In 1918 two long drifts were driven from the tunnel, one of 1720 ft. to connect with the Cresson shaft; the other 2000 ft. connecting with the Portland No. 2 shaft, at a depth of 2133 ft.
The flow from the tunnel has varied from 17.000 gal. per min. in 1906 to the present flow of 2500 gal. The district has been effectively drained, as not a mine is pumping.

202Info Title:
Roosevelt Tunnel Illumination Method Electric lamps is the type of Illumination chosen for the Roosevelt Tunnel.
Electric incandescent lamps possess a number of advantages for tunnel work. They give a brilliant and steady light—one that is not affected by drafts and neither pollutes the air with soot nor vitiates it by consuming the oxygen. By combining several of them in a cluster, plenty of light in the heading is obtained for the drillers and shovelers, tending toward efficiency. To offset this advantage, however, the fact remains that unless they are used in connection with electric locomotives, drills, or similar machinery, the cost of lamp installation is almost prohibitive; even with the electric appliances in use the extra wiring and the lamps themselves are expensive, while the latter are subject to considerable loss through breakage. Electric lamps are also at a disadvantage because they are not easily portable and the removal and replacement of bulbs and wires in the heading before and after blasting complicate an already involved situation. Moreover, this means of illumination is uncertain, especially in wet tunnels, because the chance occurrence of a short circuit through moisture, accident, or carelessness throws the entire work in darkness, and if other means of lighting are not at hand, stops all work until the trouble can be remedied. Again, whereas the use of electricity under ground is always attended with some danger, this is especially true in the case of lighting appliances; the supposition is that the wires are protected, but the rough usage which they are subjected soon destroys insulation, rendering persons who handle them (as they must do frequently) subject to severe shock.

236Info Title:
Roosevelt Tunnel Ammunition Used The Roosevelt Tunnel used Gelatine as Kind of Dynamite Used, with a Strength of 40%, 60% and 100%.
Gelatine dynamite is a combination of a certain amount of blasting gelatine (varying according to the strength desired) and a suitable absorbent. The former is made by adding a small percentage of gun-cotton (nitrocellulose) to liquid nitroglycerin, thus producing a jelly-like mass that has greater explosive qualities than either of its constituents, but which is much less sensitive to shock than nitroglycerine. The absorbent is usually some combustible material (wood pulp is frequently employed) to which has been added a sufficient amount of sodium nitrate to supply the necessary oxygen for its combustion. By the use of such a combustible absorbent, instead of the inert one formerly employed with straight nitroglycerine dynamite, the gases generated by the burning of the wood pulp add to the volume produced by the detonation of the explosive constituent, and the extra heat generated in this combustion adds greatly to the total intensity of the reaction.

Roosevelt Deep Drainage Tunnel Report Abstracts Engineer T. R. Countryman of the Roosevelt Deep Drainage tunnel has submitted to T. R. Watterton, secretary of the tunnel company, a report of the water measurement made at the portal on Dec. 1, which shows an average flow of 8,650 gallons each minute.
The water subsided in the Gold Coin shaft, which is in the east end of the district, four feet and nine inches, during the month of November, while the subsidence in the Elkton and Mary McKinney shafts for the same period was about eight feet.
The total recession of the water since the drainage through the tunnel was commenced is estimated by Mr. Countryman at from 199 to 225 feet. At the present time he estimates the subsidence as between three and four inches per day, and predicts that the present flow of water through the portal of the tunnel will continue for a long time.

According to T. R. Countryman, engineer for the Cripple Creek Drainage association, the total flow from the portal of the Roosevelt drainage tunnel, as measured September 16, 1912, amounts to 9,750 gallons per minute.
The subsidence of the water at the Gold Coin shaft of Granite company during the first half of the month was approximately four feet, or considerably less than the average during August. This shaft appears to be more easily affected by the surface waters and at the present time is not a fair measure of the average drop of the water in other properties.

Roosevelt Tunnel SuccessTHE SUCCESS OF THE ROOSEVELT TUNNEL.
——————
Although it has only just started its work of draining the Cripple Creek district, the Roosevelt tunnel already has more than paid for itself, according to the report of Engineer T. R. Countryman to the directors of the tunnel company.
The tunnel cost $576,000 and its total length is 16,857 ft. Of the money contributed toward its construction about $2,000 remains on hand.
The cost of pumping in the gold camp has averaged $5,000 per vertical foot, and the tunnel already has lowered the water level by 118 ft. on March 17.
In other words, the cost of pumping to lower the water level this distance would have been $590,000, or more than the tunnel cost, even if the pumping could have been done on a scale big enough to lower the level of the water to the extent mentioned.
Mr. Countryman's report follows:
Total distance from shaft to breast, March 11, 1912, 8,876 ft.
total distance from shaft to breast, March 1, 1912, 8,817 ft.
progress March 1 to 11, 1912, 59 ft; total progress since resuming work in September, 1911, 1,113 ft.
total length of tunnel, portal to breast, 16,857 ft.
March 9 a heavy flow was encountered in the breast of the tunnel where apparently a large soft vein or dike was cut. The ground kept caving continually and it was found impossible to remove the broken rock.
The flow gradually increased until the amount flowing from breast as measured March 11 was 5,240 gallons per minute. The total flow at the portal, measured the same day, was approximately 17,500 gallons.
This has since slightly decreased, probably 1,000 to 1,500 gallons. The total subsidence at the Gold Coin shaft of the Granite company as measured March 17 amounted to 118 ft., or about 8 ft. from March 1 to 17.
This would be at the rate of about 15 ft. per month. This probably will prove to be the maximum rate of subsidence.

Cripple Creek Drainage Tunnel Co. Declared Roosevelt Tunnel Officially CompletedA Notable Achievement
———
Since the first flow of water was encountered in the Roosevelt drainage tunnel at Cripple Creek it has required nearly 18 months to secure the results that were originally desired.

By this is meant that the recession of water is sufficient to outreach the development needs of the operators. The water level is being lowered at a rate of perhaps 15 feet per month. The accomplishments of last year have been enough to permit sinking and development to a deeper level, and hence forth, there is no reason to doubt, the properties will be dry.
Recent driving in the main heading of the drainage tunnel has opened a new water course, and a late report is that the outflow is about 17,000 gallons a minute. This water strike was made in the vicinity of the Gold Dollar vein system, near the northeast line of the St. Thomas claim, and it may be accepted as the completion of the huge co-operative drainage enterprise which was begun nearly six years ago.
The effects are felt in the extreme eastern portion of the district, where such properties as the Vindicator and Golden Cycle, whose workings have hitherto been apparently uninfluenced, give evidence of being benefited.
With this work completed, the supreme interest of operators will center in the deep developments. Already some of the mines have taken advantage of the disappearance of the water and have undertaken explorations at lower levels. The extension of productive veins has been proven in two or three cases.
The level of the Roosevelt tunnel is 750 feet deeper than that of the previous tunnel, so that a great deal of room exists for exploration and for discovery, if the gold deposits prove themselves persistent. Operators show themselves confident, while the stock market at Colorado Springs is reflecting in some measure the more optimistic sentiments of investors.
At a meeting of the directors of the Cripple Creek Drainage Tunnel Co., held Monday, the new tunnel was declared to be officially completed. No further work will be done in extending the bore, as the directors consider that they have accomplished the design of the operators. The tunnel has cost the district about $500,000, and after paying all bills a small cash balance will remain in the treasury, to be used in keeping the bore clear of debris.

Roosevelt Tunnel Keeps on Draining The future of the Cripple Creek district now looks brighter because of the increased effectiveness of the Roosevelt deep-drainage adit, which is now draining the mining area at the rate of 82 ft. per month.
The El Paso mine is dry to the drainage-adit level, which is 1338 ft. below the shaft collar, the Portland has recovered its 1500-ft. level, and the Independence its 1000-ft. station. This will make possible the mining of the deeper levels and, presumably, an increased production of high-grade ore.

Roosevelt Tunnel Still Drains In 1907 the lowest of the numerous adits driven to secure drainage, the so-called Roosevelt tunnel, was started, and has been in progress ever since. Some months ago, the breast had reached a point at which it might have been expected to develop a large flow, but the results were disappointing. Those in charge of the enterprise persisted, however, and their persistence was finally rewarded, for during the last week of November, the two drifts on the C. K. & N. vein developed a flow of 5500 gal. per min., and the total flow from the adit is now nearly 9000 gal. per min., corresponding to a rapid decrease in the water-level of the district.
The Battle mountain mines are being un-watered at the rate of 3.1 in. per day and the Portland has already recovered its 1500-ft. level, while the 1050-ft. level of the Stratton's Independence, flooded since 1907, has also been recovered.
Production in the district will be greatly stimulated, and a "boom" is confidently expected.

Roosevelt Tunnel Fast Draining Eastern Slope of Cripple Creek DistrictCRIPPLE CREEK DRAINAGE.
———
General Manager Frank Smale of the Portland Gold Mining Co. reports that the Roosevelt tunnel is fast draining the eastern slope of the Cripple Creek district. The water is now several feet below the collar of the lowest level of the Portland and is receding very rapidly.
According to Superintendent Fuller the drainage tunnel water is being opened every day in the main heading, and he declares that at this time about half of the water flowing from the tunnel is coming from the main tunnel. In the heading of the tunnel the formation has changed to a breccia and it is not breaking as well as the phonolite.
The necessary changes have been made to the compressor at the intermediate shaft and things are working smoothly. Until the money in the treasury is exhausted it will be continued, in all probability, toward the Requa Savage side line. The heading of the tunnel is now near that point on the east slope of Beacon hill.

Roosevelt Tunnel Extension Choices Denver Dec. 2—The question of extending the deep-drainage tunnel is now being considered, and whether to drive the main heading or to continue driving on the C. K. & N. vein, of the El Paso company, from the Fuller crosscut, and from which three-fourths of the present flow of 800 gal. per min. is coming.
The argument against this is that the management should not go on developing El Paso ground; the argument for it is that the two tunnels driven prior to this one, developed all the water and drained a large part of the district from the C. K. & N. vein.
The present tunnel heading is in red granite and the breccia area of Raven hill has not yet been reached, at which contact a larger body of water might be developed.

Drainage Tunnel Effect Reports Denver Nov. 25—Reports of the good effects of the recent flow of water opened by the deep drainage tunnel in the Cripple Creek gold mines, are coming in rapidly, and it is now apparent that in all probability the deep levels of the mines over nearly the entire camp will be unwatered.
It is reported that the 1050-ft. level of Stratton's Independence, after being drowned since 1907, is now dry and being worked.
In the Portland mine, Manager Frank Small states that the water is only 30 in. above the 1050-ft. level, and that in four days the water receded 9¼ in. This level will be worked again soon.
In the Gold Coin shaft the water is said to have receded 3 ft.
In the C. K. & N. vein of the El Paso company a large body of high-grade ore has been opened in the south drift from the Fuller crosscut on the tunnel level. Twenty feet of drifting on the orebody has already been done. The 1000-ft. level of the El Paso shaft has been reclaimed and is being cleaned of the seven years' accumulation of debris.
At present the flow from the portal of the tunnel, according to Engineer Countryman's measurement, is 8000 gal. per min., and in the shafts of the mines on Battle mountain the water is receding at the rate of 3 in. per day. In the tunnel heading the rock is close and hard and but little water is coming from it. More than three-fourths of the entire flow is coming from the C. K. & N. vein.

Deep Mining in Cripple CreekCRIPPLE CREEK DRAINAGE.
———
Engineer T. R. Countryman reports the flow through the portal of the Roosevelt tunnel at Cripple Creek, Colo., as about 8,000 gallons a minute. The recession in the Battle mountain shafts is 3 in. a day and in other parts of the camp the average fall is about the same.
In the main tunnel the heading has passed through the Black Bell water course and is now in hard and closed ground, with little water being opened. Three-fourths of the water coming from the tunnel is from the C. K. & N. vein, which is the chief water course of the district.
The tunnel has drained the Portland mine on the 1,500 ft. level and the announcement is made from the company's offices that a force of men will be put to work early in December sinking winzes from that point in the mine. It is expected that within the next few months a new level will be made ready for development.
The management of the Portland Co. is of the opinion that the deep drainage tunnel has solved the water problem so far as its own property is concerned, and that the water level will continue to drop at a rate that will keep in advance of development work.
The water has receded 3 ft. in the Gold Coin Shaft, which is better than was expected. Some recession has occurred in the Strong shaft just east of the Gold Coin. With the possible exception of the Vindicator and Golden Cycle shafts, all of the deeper mines of the district will be immediately affected.
After being filled with water since 1907, the Stratton’s Independence has recovered the 1,050-ft. level of the main shaft and work has been resumed there by Davis and Hyler of Victor, who have begun taking out ore they left when water drove them out.
Little development has been done at this depth and it is expected that some of the ore shoots found in the upper levels will be found there.
In drifting south on the C. K. & N. vein from the Fuller crosscut in El Paso territory values have been encountered to the great depth 1,350 ft., which is 500 to 700 ft. deeper than it has been possible to open ore in the Cripple Creek district before.

Roosevelt Drainage Tunnel Struck Large Flow of WaterCripple Creek Drainage
Denver Correspondence
On Friday night, Nov. 11, at a point 15,956 ft. from the portal of the Cripple Creek deep-drainage tunnel, a large flow of water was struck and so suddenly that some of the men employed barely escaped with their lives.
At present the flow is about 12,000 gal. per min. from the portal, but it will probably decrease somewhat from that.
In the C. K. & N. property, just above the drainage tunnel on Beacon hill, it is stated that the water has dropped 70 ft. during the last four days.
The Portland mine is said to be dry in its lowest workings, which will save $10,000 per month in pumping expenses.
The El Paso mine is also dry and work will be commenced at once in the 1000-ft. level.
No official measurements of the lowering of the water in the mines have yet been taken but it is said to be receding in all but the extreme eastern mines of the district.
To date the approximate cost of the tunnel has been $545,000 and it was commenced in July, 1907; the depth of the tunnel below the average water level in the mines of the district is about 730 ft. Its course is north 44 deg. 20 min. east for 14,845 ft. to a point 65 ft. east of the main shaft of the El Paso mine on Beacon hill and thence north 70 deg. east toward the Vindicator shaft on Bull hill.
At the heading where the work is going on the rock is comparatively dry. Whether the whole district will be permanently benefited by this new flow of water, will be definitely known in a few days.

Its course is north 44 deg. 20 min. east for 14,845 ft. to a point 65 ft. east of the main shaft of the El Paso mine on Beacon hill and thence north 70 deg. east toward the Vindicator shaft on Bull hill. At the heading where the work is going on the rock is comparatively dry. Whether the whole district will be permanently benefited by this new flow of water, will be definitely known in a few days.Internet Source Text Link(s) {Found/Seen/Known]:

Portland Dry Below 1500-Foot Portland—One of the permanent good effects of the recent flow of water encountered in the deep drainage tunnel is the fact that the Portland mine, on Nov. 14, was dry below the lowest or 1500-ft. level, and it is considerably over a mile in a straight line from the tunnel heading to the above mine, which in the past has produced gold ore worth $35,000,000, and paid nearly $9,000,000 in dividends.
It is now believed that the entire camp will be drained, making an average of 730 ft. in depth over the whole district, which can now be mined without the enormous cost of pumping hitherto involved.

Roosevelt Deep Drainage Tunnel Co. To Extend Its Own TunnelCRIPPLE CREEK DRAINAGE.
———
The executive committee of the Roosevelt Deep Drainage Tunnel Co. of Cripple Creek, Colo., has decided to do its own work in extending the bore down 1,300 to 1,500 ft. This action was taken on account of the high bids presented by contractors for the work. The committee rejected all bids and recommended to the directors that Charles A. Fuller, who drove the tunnel, be placed in charge of the new work.
Fuller has men at work repairing the track, changing air pipes and getting ready for operations. Money to perform the work has been subscribed. In order to run the tunnel the additional distance $40,000 was required.
Engineer T. R. Countryman of the tunnel company says the water is about 5 ft. above the 1,000-ft. station in the El Paso shaft.
The water has receded about 65 ft. since the first water course was tapped.

Roosevelt Tunnel Will Continue Denver Sept. 12—A. E. Carlton, one of the directors of the Cripple Creek Drainage and Tunnel Company, has announced that the money necessary to continue the work, has been raised and that work has been started; whether the tunnel will be driven straight ahead into the breccia area, or follow some of the dikes in the granite, has not yet been announced. The former of course is the only plan which can possibly be of advantage to the entire ore-bearing area.
Engineer Countryman gives the flow from the portal as 5800 gal. per min. The tunnel was started in 1907 and is in now about three miles from the portal and while it is not altogether the success that was predicted, it has been of sufficient advantage in draining the mines, to encourage the mine operators of the district to furnish the money necessary to continue the work.
The average recession of water in the mines is stated to be about five feet per month, except in the rainy season.

One party desires to continue the tunnel, which was stopped in the granite, straight ahead into the breccia area where the mines are, reaching that area somewhere close to the Elkton mine; the other party thinks it best to leave the main course, and develop a big water flow by following some of the dikes intersected. These dikes are in the granite.

Roosevelt Drainage Tunnel Shall Be Extended Denver, Sept. 1—Definite word has come that the Roosevelt drainage tunnel is to be extended. At a meeting of the directorate of the tunnel company, held in Colorado Springs, it was decided to drive the main head forward a distance of 1500 ft.
The question of finances has been the principal point at issue in holding back work upon the further extension of the tunnel, but this matter is practically settled in the announcement that $27,500 of the $50,000 required has been subscribed and that the balance will shortly be secured.
At the present time the tunnel is in 15,740 ft and has already lowered the water-level of the camp. The rate at which the water is disappearing has, however, not been sufficiently rapid to satisfy the desires of the operators, so that the news of the immediate taking up of the work will be received with much satisfaction.

Roosevelt Tunnel Not Funded for Completion Yet Denver Aug. 18—The story recently circulated in the Cripple Creek district that the necessary money for the completion of the drainage tunnel had been raised and work would commence immediately, is denied by those in authority.
It is stated that it will be some time before the subscriptions will be forthcoming, as some of the men who are expected to contribute are not in the State. Until they return there is no hope that the needed funds for driving the tunnel another 1200 ft. into Beacon hill will be raised. The present flow through the portal of the tunnel is about 5800 gal. per min. Of this, 1200 gal. is seepage water and the rest is from the main water body.
The recession in the El Paso mine is about two inches per day. An attempt will be made soon to open the well in the bottom of the El Paso shaft, connecting with the Roosevelt tunnel.

Announcement is made by the Cripple Creek Drainage Tunnel Association that the amount required for the extension of the Roosevelt deep drainage tunnel has been raised by subscription from mine-owning corporations, and that the work of driving the bore 700 ft. farther from the tunnel heading will begin at once.
The deep drainage bore, which from portal to breast now covers a distance of almost 17,000 ft., will be carried 200 ft. to the east contact of the Black Belle property and 500 ft. to the Gold Dollar Consolidated ground, both mines situated on Beacon hill.
As the ground along the tunnel line extension is not as hard as the formation previously pierced, it is believed that a driving distance of better than 12 ft. a day will be made. In carrying the bore an additional 700 ft. two water courses it is expected will be tapped, and thus double the portal flow, which is now about 6,000 gallons per minute.
The work of driving the crosscut from the tunnel level to the C. K. & N. vein will continue, but this operation will be carried on by the El Paso Co.

Roosevelt Drainage Tunnel Disappointment is NotedThe Roosevelt Drainage Tunnel
———
Some disappointment is noted with respect to the results which have thus far been achieved in the drainage of the Cripple Creek mines by the Roosevelt drainage tunnel. The deep bore will undoubtedly pay for itself, but the unwatering of the area has been making slower progress than was hoped for, owing to the greater compactness of the formation at the lower levels now being drained.
Aside from the workings of the El Paso mine and the influence which they have upon the territory immediately surrounding, no exceptional water channel has been cut. Hitherto the flow from the tunnel has been largely supplied by the El Paso ground, which has immediate drill-hole connection with the bore.
Taking the camp throughout, the recession of the water level has progressed only about 50 ft. during the first six months since the tunnel pierced the breccia. It had been the expectation that a 100-ft. zone would be relieved of its burden of water in time to prepare the way for sinking in a number of shafts this summer, inasmuch as it is not advisable to undertake anything less than a 100-ft. lift.
Since the flow from the El Paso workings has been abating, the total output is less than 6,000 gallons per mine, or sufficient, perhaps, to insure the unwatering of a 100-ft. zone by the first of next year. Accordingly, the operators are raising funds to carry the breast of the tunnel ahead for another 1,200 ft., in the hope of securing more rapid results.
Judging by the present seepage, which will naturally decrease in rate as the water level goes down, the Roosevelt tunnel will require as much as 10 years to fulfill its destiny, unless the bore is continued under the district and a more thorough prospecting for water is carried on.
The officers of the tunnel association realize the importance of more work at this time, and it may be accepted as certain that the bore will be going ahead at an early date. The cost of the Roosevelt tunnel thus far as been about $540,000, and the miners feel the need of early returns from this large investment, even though a little more must be spent upon it.
In this connection it is to be noted that the drainage district act which was passed by the Colorado Legislature at the solicitation of the mining interests, particularly those of Cripple Creek, has been permitted to become a law by the governor, though without his signature.
Until the Roosevelt tunnel has proved its efficiency there is no immediate likelihood of any mine drainage district being established in the state, inasmuch as Cripple Creek is the only section which has held such a step in contemplation.

Since the flow from the El Paso workings has been abating, the total output is less than 6,000 gallons per mine, or sufficient, perhaps, to insure the unwatering of a 100-ft. zone by the first of next year. Accordingly, the operators are raising funds to carry the breast of the tunnel ahead for another 1,200 ft., in the hope of securing more rapid results. Judging by the present seepage, which will naturally decrease in rate as the water level goes down, the Roosevelt tunnel will require as much as 10 years to fulfill its destiny, unless the bore is continued under the district and a more thorough prospecting for water is carried on. The officers of the tunnel association realize the importance of more work at this time, and it may be accepted as certain that the bore will be going ahead at an early date. The cost of the Roosevelt tunnel thus far as been about $540,000, and the miners feel the need of early returns from this large investment, even though a little more must be spent upon it. In this connection it is to be noted that the drainage district act which was passed by the Colorado Legislature at the solicitation of the mining interests, particularly those of Cripple Creek, has been permitted to become a law by the governor, though without his signature. Until the Roosevelt tunnel has proved its efficiency there is no immediate likelihood of any mine drainage district being established in the state, inasmuch as Cripple Creek is the only section which has held such a step in contemplation.Internet Source Text Link(s) {Found/Seen/Known]:

Deep Drainage Tunnel DoneCRIPPLE CREEK DRAINAGE.
———
The directors of the deep drainage tunnel at Cripple Creek have decided that no new development will be done for the present at least. There was some talk of extending the bore 2,000 ft. from the present heading, but as the cost would be $40,000 and the tunnel is draining the district, although at a slower rate than was anticipated, the directors believe it would not be wise to spend any more money on development until it has been proved that the present tunnel will not do all the work expected.

Roosevelt Tunnel Happenings At a meeting of the directors of the Cripple Creek Drainage and Tunnel Co. in Colorado Springs the El Paso Consolidated Gold Mining Co. made an agreement to advance the Fuller crosscut another 125 ft. and will be paid $20 a foot for the work in the event that 2,000 gal. or more of water per minute is developed in that space.
If water from 1,000 gal. to 2,000 gal. be developed the El Paso will be paid half of the amount of the agreement, or $10 a foot. Should no water be developed, the El Paso stands the loser.
In the meantime, while the Fuller crosscut is being advanced, the directors are making arrangements to continue the main heading of the tunnel in the direction of the Elkton shaft.
According to Mr. Countryman, the water is receding at the rate of 20 inches a week. This is true from the eastern as well as in the western part of the camp.

———
What is believed to be the principal water course of the district, sought to be tapped by the Roosevelt drainage tunnel in the Cripple Creek district was tapped last week in the Fuller crosscut to the C. K. & N. vein, when two drill holes released a flow of water of tremendous force. Once that the heading is opened up as to permit a free course for the water, it is expected the flow of water will increase to 10,000 gal. per minute.
The lowering of the water is very perceptible all over the camp and in the last few days the water has gone down at the rate of 1 ft. each day.
The report of Engineer T. R. Countryman to the directors of the tunnel company on the proposed deep drainage tunnel will be made at an early date. The maps of the routes will be given and the cost of construction approximated.

Cripple Creek Deep Drainage Tunnel Co. Officers Thinks of New Tunnel That the Roosevelt drainage tunnel, which is not completed, but which is already unwatering a vast area in this camp, will have outlived its usefulness within the next eight years, and that a third and still deeper drainage bore will be necessary is the opinion of the officers of the Cripple Creek Deep Drainage Tunnel Co., which held its annual meeting at Colorado Springs.
Anticipating the necessity of building a third drainage tunnel, the directors of the company authorized its mining engineer, T. R. Countryman, to take preliminary steps for the surveying of this proposed tunnel. It is believed the cost of the third tunnel will not exceed $500,000. It will drain the camp 500 ft. below the level of the Roosevelt tunnel. It is proposed to start work on the third bore in ample time to have it completed before the mines of Cripple Creek can reach the level of the Roosevelt bore, and thus avoid suspension of operations.

Cripple Creek Drainage Tunnel HappeningsCRIPPLE CREEK DRAINAGE TUNNEL.
———
An additional shaft has been put to work in the Cripple Creek drainage tunnel, driving the crosscut from the tunnel level to the C. K. & N. vein and water course. The distance to be covered is approximately 600 ft., and it is expected to complete the work within 60 days. Of the 6,000 gal. or more a minute pouring from the portal of the drainage tunnel, 5,000 gal. come from the hole in the El Paso shaft.
Superintendent Fuller, under the direction of Engineer T. R. Countryman, has started to cut a station in the tunnel at a point west of the El Paso shaft connection. This is being done preparatory to extending a crosscut to the C. K. & N. water course.
It is said that it was this water course which was cut some five years ago by Superintendent Bainbridge, that then flooded the El Paso property. It was expected that the main tunnel would tap the water course in the Black Bell property, but this having failed, it is now deemed advisable to drive over to the C. K. & N.
The 700 and 800-ft. levels of the El Paso have already been recovered. The water is receding in the Elkton shaft at the rate of 2 ft. a week. Preparations are now being made by the company to sink the shaft. A hoist is now being installed on the ninth, or the bottom level.

Roosevelt Tunnel Will Have an Impact The recent connection of the Roosevelt tunnel at Cripple Creek with the El Paso shaft, is regarded as an event which will have an important bearing on the immediate future of Colorado mining and metallurgy. The Roosevelt tunnel has been driven about 16,000 ft. and has 14,000 ft. yet to be driven before its objective point is reached.
In the latter portion of its course it will effect the drainage of the area which has a common water level and which contains numerous gold-bearing veins.
In view of the undoubted efficacy of the cyanide process in the treatment of these ores the completion of the tunnel will undoubtedly open the way for the erection of new mills and the creation of a new metallurgical era for Cripple Creek.

Deep Drainage Tunnel Effects Denver, Dec. 5—Computation by a competent engineer shows that it would cost 6½ times more to drain the Cripple Creek district to the present depth of the deep-drainage tunnel by pumping than by the tunnel.
This will convey an idea of the benefits to be derived from this great work, which has just been completed through the dry, hard granite "rim," or surrounding country rock, into the more porous and spongy volcanic breccia area, which contains the gold-bearing veins, and also the vast amount of water which it is desired to liberate, and which is expected to unwater the mines an average of 730 ft. below their present lowest workings.
One big mine, the El Paso, has already been unwatered, and it is stated today that in all mines on Beacon hill, the Mary McKinney and Elkton especially, the water has lowered 5 ft. or more, though the mines at the extreme east of the camp have not yet shown any lowering.
The drainage will, of course, be slow, as may be gathered from the fact that in September, 1904, according to careful records kept by the engineer of the Cripple Creek drainage tunnel (the next one above the Roosevelt, or deep drainage), the amount of water drained to lower one vertical foot in the principal shafts in the district was 58,109,000 gal., and that the removal of 4115 gal. per min. only lowered the water level in the central and western groups of mines at the rate of 4 ft. per month.

The tunnel with its further extensions is expected to drain the mines of the district to a depth of 730 ft. below the present water level.
The total length of the tunnel is approximately three miles.
The rock (Pike's Peak granite) is so solid that except for a short distance near the portal no timbering has been required. The size of the tunnel will permit its use for transportation with a double track, but this will not be practicable unless a mill is built at the portal to handle the ore.
Voluntary subscriptions provided the funds needed in the construction of this tunnel. The Cripple Creek Drainage and Tunnel Company was organized in August, 1906, under the laws of Colorado and was authorized to issue 1,000,000 shares, par value, $1.
The accompanying table shows the list of companies who contributed to the construction of this tunnel.
The work on the tunnel began in May, 1907, and most of its was done under contract by A. E. Carlton.

Deep Drainage Tunnel Drained Lower El Paso Mine Denver, Nov. 27—The lower levels of the El Paso mine, at Cripple Creek, are now un-watered by the connection with the deep drainage tunnel, and the rich ore said to exist there will, after some necessary timbering, be available.
No special waterway or ditch has been cut in the main tunnel, and as 2000 gal. per min. has been flowing through it, mainly from the El Paso mine, work is being carried on from the intermediate shaft instead of from the portal.
Apparently at this writing the "main water course," as it is called, has not been reached by the tunnel, but it is expected daily. A great deal has been written by the nontechnical press about "tapping the underground lake."
That the 3½ miles square, which is a network of dikes, veins and cross fissures, has a common water level seems natural enough, and, in fact, has been proved by the higher drainage tunnels to be the case, but the "underground lake" theory, with perchance eyeless fishes swimming about in it, is hardly tenable.

Deep Drainage Tunnel Might Soon Be Completed Denver, Nov. 20—Apparently the deep-drainage tunnel at Cripple Creek has entered the breccia area, and the flow of water does not exceed 1000 gal. per min.
At a meeting of the directors, the contractor was authorized to drive 200 ft. further, unless a flow of 2000 gal. per minute is secured inside that distance, when the contract will be considered completed.
The total length of the tunnel is now 15,524 ft. The present cost is $28 per ft., and $23,000 of the total subscribed, amounting to $550,000, is still in the treasury.

Roosevelt Drainage Tunnel Draining El PasoTHE CRIPPLE CREEK DRAINAGE TUNNEL.
———
Water has at last been released from the workings of the El Paso mine workings above the connection with the Roosevelt drainage tunnel at Cripple Creek, and it is now flowing at the rate of about 2,000 gallons a minute. The water has already receded in the mine below the 800-foot level.
The directors of the tunnel company last week authorized Contractor Carlton to continue under his contract for 200 feet from the present breast of the tunnel. If he secures a flow of 2,000 gallons a minute before he has bored 200 feet, his contract will be completed, but if the necessary flow is not secured in that distance, cross-cutting will be started to tap some of the lateral water courses.
The total length of the tunnel was 15,524 feet at the time this action was taken, and the cost has been $27,000, leaving $23,000 unexpended from the original fund subscribed.
This balance will be used to bore the 200 additional feet authorized and for lateral cross-cutting and miscellaneous expenses.
Because there is no trench in the bottom of the first 1,400 feet of the tunnel, operations from the portal have ceased and are now conducted through the intermediate shaft.
The heading of the tunnel is now at a place directly under the end of the upper or original drainage tunnel, which will soon be dry.

Deep Drainage Tunnel and El Paso Connected Denver, Nov. 15—Connection has been made by the deep-drainage tunnel with the El Paso shaft, and it is stated that A. L. Burris, manager of the latter, expects to begin mining in the hitherto drowned levels in a few days.
The ore in these limits is known to be exceptionally rich. What is supposed to be the main water course of the district is yet 70 ft. ahead of the tunnel breast.
It is believed that it will drain the mines of the west side of the district, but that possibly it would have to be driven 12,000 ft. further to unwater the Bull hill section. The drainage tunnel was financed by the big mining companies of the camp.
The El Paso company subscribed $133,000.

Fear of Too Much Water Between El Paso Shaft and Roosevelt Tunnel Fearing that to increase the flow of water through the drainage tunnel by way of the well in the El Paso shaft might hamper the work in the heading, it has been arranged between the tunnel company and Allen Burris to leave the present flow of water as it is until such time as it is figured a greater flow can be handled.
For this reason the casing in the bottom of the shaft was not cut and the water that is now going through the well comes from two small courses cut in the drilling of the well.

First Water Ran Through Roosevelt Tunnel The first water has been run through the new drainage tunnel at Cripple Creek. Late last week the drill hole connection from the El Paso shaft on Beacon hill was completed and a small amount of water let through. It is not the intention, however, to open up the El Paso until the main water course of the district has been completed, which is expected this month.
This will practically finish the tunnel for the present. It is the opinion of engineers that the water will not lower more rapidly than 10 ft. a month, so that it will require the full results of drainage.

Roosevelt Tunnel Happenings Unexpected obstacles have interfered with the plant to make a churn drill connection between the El Paso shaft at Cripple Creek and the Roosevelt drainage tunnel. The drillers had sunk only a short distance when they encountered a steel bulkhead, and when they ran into some steel plugs later they gave up the undertaking.
The management has let a contract for an upraise from the tunnel to the shaft. This will require a longer time for completion, but will have the same effect in draining the workings of the El Paso. Although the drainage tunnel has been driven into El Paso ground, it has still about 800 ft. ahead in the granite before it reaches the eruptives and the first water course, which will probably be about the first of November.
With the approaching completion of the tunnel, Cripple Creek operators are making arrangements for mining at depths from which they have long been barred.
The Strong will be one of the first mines to be benefited, and the Strong Mining Co. is preparing to sink its shaft No. 2 on Battle mountain, to reach the ore shoots opened in the lower drifts. The work will begin within a few weeks.

Deep Drainage Tunnel Plans for Connecting with El Paso Main Shaft Engineer T. R. Countryman, representing the Cripple Creek Drainage and Tunnel Co., has submitted plans for the crosscut to connect with the churn drill hole, being bored from the bottom of the El Paso shaft for the purpose of unwatering that mine's workings and those of other properties.
The crosscut will be carried straight for 40 ft. with a right angle turn at that point, and then direct to the point where the drill will break through. This turn is to prevent the water shooting out direct into the tunnel. The crosscut will be completed before the hole is down to the tunnel level, and a bulkhead of 10 by 12 timbers will be solidly constructed to hold back the flood waters. In the floor of the crosscut will be held an 18-in. steel pipe of great strength, set in cement, through which the flow of water will be regulated by a screw valve.
With a head of 750 ft. of water the pressure will be enormous, and extreme precautions have been deemed necessary. The heading of the tunnel is now less than 200 feet from the point where the crosscut will be started, and it is expected this distance will be covered within 15 days. The crosscutting will be done by miners of the El Paso Co.

Mon-Anchor to Resume Work Due to Drainage Tunnel Denver, July 25—The approaching connection of the deep drainage tunnel with the El Paso workings, and the expected unwatering of most of the deep mines of Cripple Creek, is stimulating new operations in a large degree.
One instance of this is the Moon-Anchor, on Gold hill, which has produced $1,500,000 in the past, and struck water at 960 ft. Work is to be resumed on company account about Aug. 1.

Roosevelt Deep Drainage Tunnel Almost Done Denver, July 11—The El Paso Consolidated Mining Company, on Beacon hill, in the Cripple Creek district, has commenced the drilling of the 8-in. hole to connect with the drainage tunnel. It is 14,484 ft. from the portal of the Roosevelt (more commonly known as the Deep Drainage) tunnel to a point 65-ft. east of the El Paso shaft, 14,000 ft. of which has been completed, leaving only about 484 ft. to be driven.
Colonel Roosevelt will be here about the time that work is finished, and it is hoped that the releasing of the subterranean waters by the turning of a valve will be placed in the hands of the ex-President an event which will be duly celebrated.

Roosevelt Tunnel Nearing Completion Denver, June 27—The Cripple Creek deep-drainage tunnel is a cooperative enterprise, and is built by subscription from the big mines of the district, and will probably be used for drainage purposes only.
It will be about three miles in length, and will render available without pumping about the same amount of virgin ground as the Newhouse, and owing to the fact that many of the biggest mines have latterly been producing rich ore from the lowest depths yet attained, the completion of the Roosevelt tunnel will cause a great revival in this phenomenal camp.
It may be noted in connection with this class of work that while none of the rock-boring machines for driving tunnels without explosives have yet been proved a success, the old methods with machine drills and explosives have greatly improved, for while five years ago an 8x9-ft. heading making a continuous average of 10 ft. per day was considered a great achievement, 14 ft. per diem is now not considered anything extraordinary.
"If you can put in a round of holes, say, for instance, four or five feet deep in granite, and then blow it out at one shot, why employ unwieldy and enormously expensive machinery to take it out bit by bit?" seems to be a query that is taking fast hold in the minds of technical engineers.
Of course, the latter may come, but it is here not yet.

Water Lowering at Old Gold A noticeable lowering of the water in the main shaft of the Old Gold company, on the western slope of Beacon hill, has taken place recently, and is attributed to the Roosevelt deep drainage tunnel.
The water has fallen 7 ft. below the station at the 400-ft. level, where previously the level was wet, and the miners found gum boots necessary, while ore trams were pushed out of the shaft with the wheels submerged.
The property is under lease to Joseph Brentlinger and associates, and is producing good average ore. The shaft is 480 ft. deep, and as soon as relief is further afforded by the drainage tunnel deeper mining will commence.

Roosevelt Tunnel Reached 12,245 Feet and Doing Good Progress Measurements taken recently at the Roosevelt deep drainage tunnel, when inspection was made of the dike just passed through, show the bore to have been driven 12,245 feet.
The breast of the tunnel is approximately 2,285 feet from the El Paso shaft, and is passing through from 12 to 15 feet every 24 hours.
The dike, the first to be encountered since the eruptive area of Beacon hill was entered, measures 30 feet across, and a grab sample of the quartz has shown good values of low milling grade. The dike filling is a disintegrated granite, with some basalt, an unusual occurrence for Beacon hill, where the dike matter exposed in the different mine workings has been either granite schist or phonolite.
Water was also encountered and is flowing from the roof and sides of the dike at the estimated rate of about 100 gallons a minute. No attempt will be made at this time to prospect the dike, but it is expected that with the tunnel completed, the owners of the several properties intersected by the tunnel will undertake the deep developmnt of their respective properties therefrom.

Roosevelt Tunnel Making Progress Roosevelt drainage adit is making excellent progress and is expected in eight or ten months to reach the water-filled breccia. If the flow encountered be only as large as in the El Paso (7000 gal. per min.), it may be expected that the waterlevel will be lowered at a rate of 6 to 8 ft. per month.
Since at greater depth the head will be larger, the flow should also be faster and even speedier benefits may accrue. The water present in the district is estimated at 46 million gallons per foot of depth, the figures being based upon the discharge at the El Paso adit.
To pump this would cost, according to records, $125 per million gallons, and would entail a continued and unknown cost to take care of surface waters. The anxiety, therefore, with which operators await the completion of the drainage adit can well be understood.

Roosevelt Tunnel Advances Denver, Dec. 4—The Cripple Creek drainage tunnel during November was advanced 298 ft. The full distance driven to Dec. 1 is 11,705 ft. The heading has been driven over 700 ft. into the granite of Beacon hill, and its extreme hardness has prevented more rapid progress. No moisture is observable in the breast of the tunnel, so tight is the rock, but it is expected that one of the numerous dikes traversing this section may soon be encountered and with it a flow of water. The minor water course tapped last month continuous to flow at the rate of about 100 gal. per min., but the water is carried off in the ditch and in no way interferes with work.
In anticipation of the results to be expected from the deep drainage tunnel, when the 3000 ft. of driving yet remaining is completed, properties on Beacon hill are making preparations to extend operations below the present water level.

Roosevel Drainage Tunnel with Excellent Progress Denver—At Cripple Creek the big producers have practically all stopped pumping and development, and are grubbing around in upper workings until the Roosevelt adit shall be completed and drain the ground.
The 'tunnel' is making excellent progress. Since June, when the portal workings were connected with those on the intermediate shaft, there has been but one heading to push. A. E. Carlton, the contractor, has three shifts of men at work, and 410 ft. was accomplished in August.
At this rate the tunnel should begin to drain the mines in about 15 months. It is expected that shortly after there will be a heavy production from the lower levels and that Cripple Creek will experience a new boom.

Roosevelt Drainage Tunnel Info James McIlwee, the superintendent of the Roosevelt drainage tunnel, is employing a selected gang of men to drive their heading at a maximum rate. When working with two shifts, an advance of 113 ft. was made in the first seven days of the present month.
They have been using a pair of the No. 6 Water Leyner drills, which make from 24 to 30 holes per day; and to effectively break this hard Pike's Peak granite they charge their holes with either an 80% dynamite, or with 100% powder, containing 92% nitroglycerine and 8% guncotton, made by the Dupont Powder Co., of New Jersey.
Taking into consideration the fact that the heading has an area of about 70 sq. ft., McIlwee is in hopes of making a new monthly world's record.

Drainage Tunnel Happenings A more powerful equipment of machinery is soon to be installed at the Intermediate shaft, which will be more able to handle the material.
The compressor now used at the portal of the drainage tunnel will be placed at the shaft and a larger one installed in its place. A station is now being cut at the bottom of the shaft and timbers will soon be in place.
This will give three headings in the prosecution of the tunnel work.

Roosevelt Deep-Drainage Tunnel is Now 2873 Feet The total length of the Roosevelt deep-drainage tunnel is now 2873 ft. During the month of July a distance of 203 ft. was made, which shows a falling off from previous months.
This is accounted for to a great extent by the extreme hardness of the rock in the heading, which has been almost impossible to break.
However, new machines are being used, and with new steel better progress is being made, and it is probable that during the present month the required distance will be made.

Roosevelt Deep Drainage Tunnel Progress The Roosevelt deep drainage tunnel has reached a distance of 2,873 ft., being driven 203 ft. during July. This shows a decrease over the distance accomplished in June, and is accounted for by the exceptional hardness of the rock. New steel and machines are being added and better progress will probably be made during the month of August.
The intermediate shaft has attained a depth of 553 ft. and was sunk 100 ft. during the month of July. At this rate the work will be completed by the end of August.

Roosevelt Tunnel Slowly Progressing The measurements taken on July 1 show a total length of the Roosevelt drainage tunnel to be 2,080 feet. The distance driven during the month of June was 187 ft.
This decrease is accounted for by the presence of an extremely hard rock difficult to drill and hard to shoot. The Intermediate shaft, on July 1, had reached a depth of 453 ft., showing a progress of 98 ft. during the month of June.
While this progress was slow, the contractors have been able to keep ahead of the contract speed. At this rate the tunnel level will be reached some time during the latter part of August.

Deep Drainage Tunnel Already Draining Cripple Creek—After a year's work on the deep drainage tunnel water is already forcing its way through the wall of the breast of the tunnel at the rate of 1,000 gals. a minute. The tunnel was started on May 11, 1907, and it was believed that it would require 10,000 ft. of driving into Grouse mountain before any of the water courses of the district would be reached, but the unexpected happened and a heavy flow is encountered with the bore in only 2,435 ft.
The cost of driving the tunnel to date is in the neighborhood of $100,000, and the estimated total cost for its completion is $750,000.

Cripple Creek Drainage & Tunnel Co. Drainage Tunnel Started in 1907 The question of drainage remained a serious problem in 1906 and led to the organization of the Cripple Creek Drainage and Tunnel Company and the pledging of sufficient funds to complete the long bore.
The intermediate tunnel plans were adopted, and work began on May 11, 1907. The adit was started in Gatch Park, at an elevation of 8,020 feet, or 723 feet lower than the El Paso tunnel, the lowest present drainage adit.
It is expected that it will take two years to reach the present main water course, 15,550 feet from the portal, then the tunnel will be driven forward to the Vindicator shaft, a total length of 27,190 feet, equivalent to 5 miles and 790 feet.

Deep Drainage Tunnel Contract Awarded Lund & StreamCripple Creek, Colorado.
Contract for Drainage Adit.
The contract for driving the drainage adit has been awarded to Charles Lund and Charles Stream, and their $20,000 bond to insure the company against all liens has been approved. A rate of 350 ft. per month is to be maintained by the contractors, the adit to be 7 by 10 ft. in the clear. The Tunnel Company will furnish all timbers, pipe, and rails, as well as the necessary power. Seventy-five per cent of the amount due each month will be paid the contractors, the remainder to be withheld until the completion of the contract.
It is proposed to sink an intermediate shaft from the surface at a distance of 9,000 ft. from the mouth. This shaft will be between 600 to 700 ft. deep and will materially decrease the time of driving the bore. A boarding-house to accommodate the employees has been started by Charles Lund, as the mouth of the adit is several miles from the town of Cripple Creek.

Deep Drainage Tunnel Plans & EquipmentsDenver, Colorado.
The Cripple Creek Adit.
—Equipment and Plans.
The bids for the driving of the drainage adit at Cripple Creek have been opened and the lowest proves to be between $20 and $21 per foot. If this bid is accepted, it will make the total cost of the completed adit considerably over $500,000. The signal importance of this deep drainage adit is derived from the fact that it will tap the main watercourse 740 ft. below the present deepest drainage, opening reserves of ore that cannot now be reached.
Its portal is in Cripple Creek canon, about six miles south of the town, and at an elevation of 8,020 ft.
From there it will be driven in a northerly direction 14,500 ft. to the workings of the El Paso mine, and, probably, thence easterly 11,000 ft. to the workings of the Vindicator.
The funds for the work have been contributed by all the principal companies operating in the district.
A shaft is likely to be sunk about 10,000 ft. from the portal, and the heading advanced both ways from this, which, with an average advance of ten feet per day in each heading, will permit the reaching of the El Paso workings in two years.
At the portal is installed a Norwalk 12-drill compressor, belt-driven from a 400-volt, 175-h.p. induction motor.
Three 50-k.w. Westinghouse step-down transformers take the power from the three-phase, 60 cycle, 6,600 volt, transmission line and deliver it to the motor, lighting-plant, and sawmill.
The power is drawn from the transmission line from Canyon City, which transmits at 20,000 volts to Fairview.
Ingersoll-Rand 3½-in. drills are used for driving.
A most serious problem in the driving of the adit will be the disposal of the waste from the adit, as the canon is extremely narrow at this point. If it were possible to drive headings from the workings of the El Paso a much greater rate of advance could be gained, but that is impossible, as the workings are now full of water to the 400-ft. level.

New Drainage Tunnel Happenings Cripple Creek, April 1. (Special Correspondence)—A corporation called the Cripple Creek Drainage & Tunnel Co. with a capital stock of 1,000,000 shares, par value of $1 per share, has been formed, with nine of the representative mine-owners of the Cripple Creek district acting as directors. This proposed tunnel will lower the water-level of the Cripple Creek district about 750 ft., and its portal is situated on the stream known as Cripple creek, and it is proposed to run it to a point near the El Paso mine, a distance of 15,000 ft., to cut the Beacon Hill water courses.
If it is found necessary, it will be extended to a point near the Vindicator mine, a further distance of about 11,000 ft. It is estimated that the first section of about 15,000 ft. will cost in the vicinity of 1400,000 and will take from two and one-half to three years to construct.
The mines, railroads, and other interested parties have subscribed for a sufficient amount of the capital stock at par to build the first section, and they propose to subscribe for a further amount, if it is found advisable to build the second section. The company is now engaged in constructing buildings and installing machinery and otherwise arranging for active work.

Gatch Park Drainage Tunnel Preporations Started Denver.—The most encouraging news of the week is the announcement that the long discussed drainage tunnel in Cripple Creek is commenced. Not that rock cutting has been entered upon, but the preliminary grading of ground constituting the approach, the construction of roadways, the erection of buildings prerequisite to the actual boring has started.
While only a part, 50 or 60 per cent of the estimated cost has been subscribed by the mine owners and operators, it is assumed that the remainder will be pledged as the work progresses.
Last week a force of men was sent to the proposed portal at Gatch Park to clear away debris and prepare sites for office, power, tool houses, and other buildings. Carpenters and other workmen will be sent out this week.
It will take two or three months to get things in readiness for the installation of machinery. Of the money pledged $750,000 has been subscribed by the mining companies, $50,000 by the railroads, and $25,000 by the mills and smelters.
A committee composed of President Bernard, Frank G. Peck and F. F. Castello has been appointed to purchase machinery and superintend the operations. A cash assessment of $40,000 has been made on the subscribers for initiatory work.

Deep Drainage Tunnel to Happen SoonDenver, Colorado.
Drainage Adit.
With the announcement of the intention of the mine owners to begin driving the deep drainage adit another note of encouragement is sounded. This adit is to have its portal in Gatch Park at an elevation of 8,020 ft., or 753 ft. lower than El Paso, the lowest of existing adits, and will go far to solving the water problem. It is expected to drive it to the main water course — a distance of 15,550 ft. — in two years.
It is then planned to continue it to the Vindicator shaft, giving a total length of 27,190 ft. This distance is to be driven in five and a half years, at a cost of $721,000. The mine owners are, wisely enough, raising a fund of $1,000,000 for this purpose.
D. W. Brunton is the consulting engineer, and, if his recommendations are carried out, the adit will be 7 ft. wide by 10 ft. high, and have a grade of one foot in 300. The heading is to be driven in both directions from a shaft 10,000 ft. from the portal and diamond-drills are to be used to hasten the work. Ventilation will be obtained by the use of positive blowers.

Deep Drainage Tunnel to Happen The most important movement during the past year was the decision definitely recorded and publicly declared, to begin and continuously prosecute the deep drainage tunnel that is to penetrate the water courses and drain them so that deep mining may be carried on without hindrance from that obstructive clement.
The plan first devised to begin at "Window in the Rock" has been abandoned for the shorter course beginning at Gatch park. It will be cheaper an may prove to be quite as effective. The cost is $1,000,000, that is to say, the principal operators are endeavoring to raise that amount. Of this total about $800000 already has been pledged, and there is little doubt that the railways and smelters involved will subscribe the remainder.
The bore will first strike and drain the El Paso whose workings at 1,000 feet are and for some time have been deluged, and terminate at the Vindicator. An intermediate shaft will be sunk at the Portland and El Paso.
This project is expected to prolong the life of the district for 20 and possibly 30 years by enabling the operators to reach the greater and perhaps richer deposits in the depths and maintain a much larger output than heretofore.
For example, it is well known that some of the most valuable ore shoots in the El Paso, C. K. and N., Old Gold, Elkton, Mary McKinney and the Portland, to go no further with the enumeration, lie below the present water level. Some of the more sanguine predict a mild renewal of the old speculative boom in stocks and sales of property when the tunnel is actually commenced, with a gradual expansion of interest as it progresses toward the El Paso.

Gatch Park Deep Drainage Tunnel Agreed UponTHE CRIPPLE CREEK DRAINAGE AND TUNNEL COMPANY.
——————
The above caption is the style of the corporate name of the company that has finally taken definite steps toward driving a deep drainage tunnel for the Cripple Creek district, Colorado. It was in October, 1905, that Mr. D. W. Brunton presented three possible projects to the mine owners of Cripple Creek, and the decision has now been reached to adopt one of them.
Although the tunnel to be driven is not the one which was considered to offer the greatest advantage to the district, it is possible that, all things considered, it is better to go ahead than quibble over details which will only result in delay in reaching the deep zones which are believed to hold out as bright a future as have those already worked.
The Gatch Park tunnel will cut the formations of the district 740 feet lower than the present El Paso tunnel; will cost approximately $700,000, and will require three years for its completion.
The capital stock of the tunnel company is $1,000,000 and it is through the sale of this to the mine owners that the funds will be raised.

New Drainage Tunnel Work to Start Within 30 Days Announcement Denver, Colo.—A. E. Carlton, of Cripple Creek, announces that work on the low level drainage tunnel will begin within 30 days. It is understood that the El Paso company has raised its subscription from $100,000 to $150,000, and that the Elkton company will give $100,000, and the Mary McKinney, $50,000. The recent stoppage of work in the El Paso, due to the striking of a water course, is hastening the arrangement for the new tunnel.

Drainage Tunnel Construction Delay The delay in commencing the actual construction of the Cripple Creek drainage tunnel is causing considerable anxiety among the larger producers.
It was thought some months ago that the matter had progressed to a point where there would be no further trouble in securing the funds, and it was thought that the two or three years of delay which had been experienced would finally witness the commencement of operations.
The point about which the present delay hinges is the method of raising the necessary funds. When the first scheme of an assessment on the annual output of the various properties was proposed, it met with some objection on the part of a few producers who were situated at a considerable distance from the proposed line of the tunnel.
These argued that some means should be adopted whereby those producers who would receive early benefit from the driving of the tunnel would pay larger proportions than those to whom the advantages would come later.
The latest plan which finds favor in the minds of many is to have the Legislature organize a drainage district, each inhabitant of which would be taxed on the value of his own holdings. It is believed that this scheme provides a more equitable method of assessing the cost of the tunnel and at the same time a more just one, inasmuch as practically all of the inhabitants in the Cripple Creek district are dependent for their sustenance upon the continuance of operations at the mines.
It is to be hoped that the controversy now in progress will result in the adoption of some scheme in the near future.

Still No Definite Arrangement Been Concluded for Proposed Deep Drainage Tunnel Denver, Colo.—No definite arrangement has been concluded for driving the proposed deep drainage tunnel at Cripple Creek. A new plan to have the railroad companies operating there put up the funds to drive the tunnel and reimburse themselves by increasing their freight rates 5 to 10 cents per ton on every car of ore taken out is being discussed, but there is little probability of its being adopted.
One thing is certain, however, that unless some definite plan is adopted and the work begun this year, that is to say before next spring, we may look for a gradual and possibly a sharp decline in output within the next 18 months.

Deep Drainage Tunnel Project Slow to Start Up Denver, Colo.—It is impossible to tell, at this writing, when the executive committee of the Cripple Creek Mine Operators' Association will be prepared to begin work on their projected deep drainage tunnel. Mr. Brunton, the consulting engineer who drew the plans, is still awaiting orders; meanwhile pending final determination, he is receiving bids for the machinery equipment.
The El Paso tunnel, constructed in 1903, has about reached the limit of its usefulness. All the leading operators of the district realize the importance of getting the new tunnel under way at the earliest practicable date, for it is an absolute certainty that the principal shafts cannot be deepened very far below their present levels until the new drainage outlet is opened.
As it will take three years to drive it, with no larger benefits accruing to any part of the time under two years from the date of commencement, all the ore taken out meanwhile must come from points above the water level. With this state of things in view it is not wise to predict any large increase of output during the next three years. It is believed, however, that the production will be maintained at the rate which has marked the last two years.

Drainage Tunnel Issues, Again Another matter of great importance to this camp the past month was the agreement reached by the Mine Owners' Association in regard to plans for the construction of the drainage tunnel. As reported in our news columns, the method of financing this scheme was agreed upon, and provided for a payment of 2% of each company's net mill and smelter returns.
This assessment to apply upon production subsequent to July 1, 1907. In order to provide funds for immediate work, a tunnel company was formed, and agreed to subscribe sufficient stock to realize $800,000 by July 1, 1906.
Following the apparent unanimity that existed in the early part of the month, there developed, a few weeks later, some opposition to the proposed tax system. This dissension took the form of a letter to the chairman of the drainage tunnel committee, and set forth that the proposed method of equal taxation was unjust, in view of the fact that equal benefits would not accrue to the different companies in the district.
As a remedy, the proposition is made that the more distant property owners should have the right to make connections with the drainage tunnel either by constructing other tunnels, or putting watertight pipes through the workings of intervening owners.
It has been thought that this remedy would prove successful if a board of arbitration were provided to sit in all such cases and make awards that the various parties should abide by.

Deep Drainage Tunnel Statistics Denver, Colorado.—A committee of Cripple Creek mine owners, at a meeting recently held, decided definitely to construct the deep drainage tunnel on the plan known as the Window Rock Tunnel. This project will cost between $800,000 and $1,000,000, and a plan to finance it is now under consideration. It is probable that the money will be raised by pro rata assessment, based on the production of the properties interested.
Following are statistics of the tunnel:
Portal to El Paso shaft, 17,200 feet;
to Black Belle shaft, 18,200 feet;
to tunnel shaft, 12,690 feet;
elevation of tunnel, 7,660 feet;
depth below portal of present tunnel, 1,130 feet;
below tunnel shaft, 1,140 feet;
from Black Belle shaft to Vindicator, the terminus, 11,640 feet, making a total of 29,840 feet from portal to Vindicator.
The cost per vertical foot drained from the portal to the Black Belle shaft will be $468, while the additional drainage to the Vindicator will bring the total amount to from $800,000 to $1,000,000. The time of constructing the tunnel is estimated by Engineer Brunton at two and one-half years to the Black Belle water course, and approximately 18 months will be required for the extension to the Vindicator. The depth gained will be 1,090 feet.
It is estimated that the tunnel shaft could be sunk at the rate of three and one-half feet daily in the headings. This is much better progress than was made in the present tunnel. This tunnel will be about ten feet in height, and not less than seven feet in diameter, to provide drainage facilities below the tracks, room for ventilating pipe, tunnel cars, etc. Three and one-half to four-inch air drills will be used, instead of the three and one-quarter drills used in the former bore.
The coarse, blocky granite through which the tunnel will be driven necessitates the large dimensions mentioned above. Double tracks will be used in all probability. The tunnel will be called upon at times to carry from 10,000 to 15,000 gallons of water per minute, so that a grade of one foot in 300 is recommended by Engineer Brunton.
The headings will be driven in both directions from the bottom of the tunnel shaft, with the pumping compartment 4x5 feet. Timbers will be about 8x8 feet, four feet apart, center to center. It is recommended by Engineer Brunton to plank the tunnel and use mules for transportation, as advantageous and economical over manpower, electricity and air locomotives.
The water flowing from the Cripple Creek tunnel now in operation will probably be used to operate an electric power plant, and surveys will be made and water rights located. After the completion of the tunnel the power will be sold in the district.
In regard to the ventilation the engineer points out that this problem has been solved and that no difficulty need be expected. Small single openings in mine drifts can be ventilated by a force blower with success.

New Deep Drainage Tunnel of Cripple CreekThe New Deep Drainage Tunnel of Cripple Creek.
The new, long and deep drainage tunnel that is to be driven under Cripple Creek is an event of the greatest importance and interest not only to Cripple Creek but to the West and the mining world generally.
It means for Cripple Creek another ten years at least of development and prosperity. The mines had reached that stage when the mine owners were not afraid of the continuance downward of probable ores, but of reaching a water level which might put a serious hindrance to further deep development. At about 1,800 feet depth, experience has shown that there is a formidable water level.
They have had experience from many mines such as the Elkton and others of what it meant when that water level is tapped. It meant that not only downward work had, in some cases, to be discontinued but that the upper and hither to dry workings might be flooded; hence it is that so few mines in so old a camp as Cripple Creek have reached the 1,800 foot-level.
They preferred extending their workings as long as they could go laterally to encountering the dread water level.
Now that fear will be dissipated and another 1,000 feet of development is before them, not for any one single mine but for the camp as a whole. Glancing over the chart in the Rocky Mountain News accompanying Mr. Brunton's able report we see that the extreme depth to which the camp has been exploited (by adding together that reached by the El Paso and American Eagles shaft) is only 2,300 feet.
The Strattons' Independence and the El Paso have reached that depth under the highest surface point in the country. Other mines have only reached 1,800 feet. A large majority have not even reached the 1,000 feet, and many are less than 500 feet deep. As regards depth, Cripple Creek, despite its age, is less deeply mined than many other camps in Colorado.
In Gilpin county, for example, there are mines upwards of 2,000 feet deep, and others below the 1,000 level.
The new tunnel will show many things:
It will prove whether or not veins continue down, whether they maintain their quantity, size and richness of ores, or whether the ore changes into other forms and combinations of high or low grade. The question of "secondary enrichment" will be proven or disproven beyond all question.
Some veins, mineral dikes and ore deposits hitherto unknown will doubtless be crosscut and discovered.
The depth to which water penetrates will be shown.
Light will also be thrown on many geological problems, such as the exact position and size of the main Cripple Creek volcanic crater and many other interesting problems of like nature.
The progress of the tunnel therefore will be looked upon with equal interest by the scientist as by the mine owner and investor. May the work go merrily on to completion. In two years we shall doubtless hear from it.
The new, long and deep drainage tunnel that is to be driven under Cripple Creek is an event of the greatest importance and interest not only to Cripple Creek but to the West and the mining world generally. It means for Cripple Creek another ten years at least of development and prosperity. The mines had reached that stage when the mine owners were not afraid of the continuance downward of probable ores, but of reaching a water level which might put a serious hindrance to further deep development. At about 1,800 feet depth, experience has shown that there is a formidable water level. They have had experience from many mines such as the Elkton and others of what it meant when that water level is tapped. It meant that not only downward work had, in some cases, to be discontinued but that the upper and hither to dry workings might be flooded; hence it is that so few mines in so old a camp as Cripple Creek have reached the 1,800 foot-level. They preferred extending their workings as long as they could go laterally to encountering the dread water level. Now that fear will be dissipated and another 1,000 feet of development is before them, not for any one single mine but for the camp as a whole. Glancing over the chart in the Rocky Mountain News accompanying Mr. Brunton's able report we see that the extreme depth to which the camp has been exploited (by adding together that reached by the El Paso and American Eagles shaft) is only 2,300 feet. The Strattons' Independence and the El Paso have reached that depth under the highest surface point in the country. Other mines have only reached 1,800 feet. A large majority have not even reached the 1,000 feet, and many are less than 500 feet deep. As regards depth, Cripple Creek, despite its age, is less deeply mined than many other camps in Colorado. In Gilpin county, for example, there are mines upwards of 2,000 feet deep, and others below the 1,000 level. The new tunnel will show many things: It will prove whether or not veins continue down, whether they maintain their quantity, size and richness of ores, or whether the ore changes into other forms and combinations of high or low grade. The question of "secondary enrichment" will be proven or disproven beyond all question. Some veins, mineral dikes and ore deposits hitherto unknown will doubtless be crosscut and discovered. The depth to which water penetrates will be shown. Light will also be thrown on many geological problems, such as the exact position and size of the main Cripple Creek volcanic crater and many other interesting problems of like nature. The progress of the tunnel therefore will be looked upon with equal interest by the scientist as by the mine owner and investor. May the work go merrily on to completion.

Drainage Tunnel Location Might Change Drainage Tunnel—The immediate commencement of the new drainage tunnel is again being talked of. In all probability a number of other surveys to determine the most feasible place to construct the bore will be begun at once. Considerable has already been done on this line.
Until recently it has been understood that the tunnel would be constructed in Cripple Creek gulch, but now there is some talk of driving from Wilson Creek gulch.
It is understood that D. W. Brunton, the well-known mining engineer, will probably be retained as consulting engineer for the tunnel.
The principal idea of the location of the tunnel is to find a site which will be the most beneficial to all the mines concerned. The new tunnel will undoubtedly be constructed by all of the mines in the district, and will be under the supervision of the Mine Owners' Association.

Drainage Tunnel Financing Issues Denver, Sept. 15—A more or less serious obstacle in the financing of the construction of the new drainage tunnel at Cripple Creek is the fact that a number of the mine owners on the east side of the district seem to be inclined to withhold their contributions until assured that their mines will be drained, since it may be three years before the Portland mine will be reached.
About $550,000—of the necessary $750,000—has been subscribed and the plan is to engage the services of a prominent engineer to explore the course of the tunnel and make recommendations in regard to its construction.

Definite announcement has been made that the projected drainage tunnel will be commenced within sixty days. Mr. A. C. Jacquith, who will be the engineer in charge, has taken steps to secure ground at the point where the portal of the tunnel is to be located.
As two years will probably be required for its completion, it will be some time before much relief will be secured, but when completed, the district will be drained between 700 and 800 feet lower than it now is.
The arrangements for rapid prosecution of this work include the sinking of the El Paso shaft as well as one at an intermediate point.
This will permit of work being carried on at four points simultaneously. The three quarters of a million dollars which the tunnel is to cost has been subscribed.

New Deep Drainage Tunnel Base Info Denver, Colorado.—The new deep drainage tunnel, which the mine owners of Cripple Creek have decided to build, will cost approximately $800,000 and will, it is believed, practically drain the whole productive area. Its total length will be 27,140 feet.
It will start at a point in the bed of Cripple creek three miles below the El Paso shaft. From the portal it will be driven in an air line northeast to the El Paso shaft, a distance of 14,000 feet, thence a little north of east to the Vindicator property, a distance of 12,640 feet.
This bore will cut the El Paso workings at an approximate depth of 1,325 feet, the Elkton at approximately 1,680 feet, the Portland at over 2,000 feet, and the Vindicator at over 2,125 feet in depth. The bore will be pushed from four working portals, including the main southern portal.
The El Paso shaft will at once be sunk to the tunnel level and the bore started north from that point. An intermediate shaft will be sunk to the tunnel level at a point midway between the El Paso and the main portal, from which point the tunnel will be driven both north and south.
It will be exclusively a drainage tunnel and its size will be determined later. The cost will be borne by the leading properties in the district drained. The former drainage tunnel for this district is 770 feet above the level of the proposed new bore.

Preliminary plans and estimates are now being made for the purpose of looking into the practicability of driving a tunnel to drain the Cripple Creek district at a depth some 1,500 feet lower than the present drainage tunnel.
This would mean the facilitating of mining operations on Bull hill to a total depth of about 4,000 feet. It is assumed by the mining men of Cripple Creek that the portal of the tunnel will be somewhere near Marigold near the old toll gate on the Canon City road.
We understand that Messrs. Hills and Willis have charge of the preliminary work on this undertaking.

New Drainage Tunnel Talks Colorado Springs, Nov. 2. The water level of the district is now standing at an elevation of 8932 feet above sea level. The effects of the El Paso drainage tunnel have been felt in more ways than one. It is now possible for companies to sink and procure additional stoping ground at a profit, besides allowing them to open up additional ground and make the ore bodies deeper.
The beneficial results of the tunnel have been demonstrated, and have helped all the mines of the district with the exception of a few located around Independence and Goldfield, all the rest being connected with the great water course that is now flowing through the portal of the drainage tunnel.
Observations made by the chief engineer, A. C. Jacquith, have been sufficient to cause the mining men of the district to commence and lay plans for another, deeper and longer tunnel, say to a depth of 2500 feet, which would guarantee that mining operations could be carried forward, without interruption from water, for the next twenty years.
Unless the deeper tunnel is run it will not be long before many of the mining companies will have to set their large pumping machinery to work again, which process, it is estimated, costs the companies $10,000 per vertical foot depth to handle the water situation of this district.
