The Plymouth Rock, of the Stratton estate on Globe Hill is now between 800 and 900 ft. but is inactive and is reported in bad working condition.

Plymouth Rock.—Ed Burke, who is leasing on this portion of the Stratton estate on Globe hill, has encountered six-ounce ore at a depth of 600 feet. An electric hoist is now being installed. Low grade ore from this lease is being shipped to the Ironclad cyanide mill.

During 1897 the Plymouth Rock shaft was opened to the considerable depth of 1,000 ft., and with the increase in depth considerable water is being encountered, as was to be expected, although the upper levels were quite dry.

Notes:

A two days' jaunt on horseback took me from Rhyolite hill, on the north, to Grouse mountain, on the south, and from Pisgah, on the west, to Wilson creek, on the east, within which boundaries some four thousand claims have been located.
The greater part of those have nothing more than the assessment work done upon them, and in many instances, this has been so indifferently done, and with such an utter abandon and disregard of the statues, that they cannot be held for a moment to comply with the legal requirements.
But, in traversing Ennis, Globe, Gold, Bull, Tenderfoot, Womack, Mineral and a score or more of hills in the district, sources of Cripple, Wilson, Requa, Squaw and other water courses, I came upon scores of properties that were being developed with more or less vigor and intelligence, some with tunnels or inclines, others with shafts or open cuts, and the owners of each full of hope and expectations.
Among those having already good indications of mineral was the Plymouth Rock lode claim in Squaw Gulch.
