Since then he has completed and furnished his Guests' House, a building which alone stands with out a peer in the state as to completeness of accommodations and grandness of interior furnishings. In March, 1899, he laid the foundation for his new Revenue stamp mill, with a ground area of 93x120 feet and height of 103 feet, the foundation of which, alone, contains six hundred perch of stone. The construction work required about 400,000 feet of lumber, and it is safe to say that it is the finest stamp mill in America, taking into consideration its water advantages and situation at the mines where everything Foundation of the Revenue Stamp Mill is handled by gravity, requiring the labor of two men for the operation of forty stamps. Leading from the mine about five hundred feet above is a tramway which discharges into a 200 ton pocket. From here the ore runs into a Cammett crusher which discharges it into a 500-ton pocket. The ore is now fed by eight automatic feeders into the eight batteries of five stamps each. From here it passes over the plates which strike the free gold, and onto a series of eight tables, the middlings of which pass onto a similar number of Frue vanners. These tables and vanners separate the heavy metallic particles from the lighter sand or waste, which are in their turn shipped to the different smelters in Montana. All of the dump cars of this mill are supplied with an automatic device, an invention of U. S. James, the construction superintendent, which unlocks the door, dumps, then closes the door and returns for another load of ore. The ore passes through the chutes by gravity, down over screens where the fine particles are separated from the coarse large rocks and passes directly into the crushers, where it is crushed and prepared for the stamps. From the stamp plates the Pulp passes by gravity onto another device planned by Mr. James, being so constructed and manipulated by certain machinery that it can be distributed to any battery by the will of the operator. In close proximity to this is situated a dial, with numbers thereon corresponding to the numbers of the different batteries. By moving a lever the ore, as it comes from the crusher, can be dumped at any group of stamps by will of the operator, giving the great advantage of supplying them with sufficient ore to keep them busy continuously. The eight plates that catch the free gold are of copper and silver plated. After the pulp passes over the tables and vanners the concentrates then pass into a pit 7x10 and 8 feet deep, in which are placed an automatic sampler, through which it all passes. This is so constructed that a uniform sample can be obtained at all times. Directly over the batteries is built a track, extending the entire length of the building, and upon which is
