 individual grouping. The Alaska Gold Mines Company, holding company, was organized for the purpose of ab- sorbing all of the stock and bonds of the Alaska Gastmeau Mining Com pany, the operating company, and also to arrange for the original financing required
 Alaska.Gastineau Plan.
 A general development program was laid out as follows:
 The mine, located in Silver Bow basin and locally known as the Per severance division, was to be devel- oped by means of raises. shafts, drifts, opening up of stopes. building Of boarding houses, compressors, trans portation system, etc, on a scale which would allow it to deliver a daily tonnage of 10000 tons. The scheme of development to be further planned so that this tonnage could be increased as rapidly as possible to 10000 tons per day.
 At Sheep creek, four miles south of Juneau, located on Gastineau chan mel. an area was taken up where the milling plants were to be erected and all necessary machine shops, boarding houses. warehouses. residential sec ton, etc, necessary to the milling plant the first unit of which would be 5000 tons were to be constructed, and such milling plant laid out on a scale where it could be increased to- 10000 tons as rapidly as possible.
 Further an electric railroad system was projected to connect this milling plant with the Perseverance mine, a distance of three miles Two miles of this railroad system comprising a great adit tunnel which was to be driven from the Sheep creek end of the properties on the strike of the lode system 70 connect with the shafts being sunk in the mine in the Perse- yvrance division, this adit tapping the ore zone 23OO feet in depth.
 This milling plant is located in what is locally known as the Sheep creek division.
 At Salmon creek, three and half miles north of Juneau. plan was laid out to develop the water power of this stream with the idea of creating stor. age Of sufficient capacity to furnish electric power throughout the year of not less than 5000 electric horse pow CT, this power to be generated at Sal mon creek and transmitted to both the mine at the Perseverance division and the mill at Sheep creek.
 In order to create this storage it was found to be necessary to build a dam of the variable radius arch type, l65 feet in height and approximately zoo feet on the crest.
 Largest Milling Plant in World.
 As soon as this above program was outlined and passed, orders were giv- en on the Sth of July, 1912, to pro- ceed on this work at the utmost speed so that the entire program of con- struction and equipment would be fin ished not later than January 1st, 1915, at which time the first unit of 5000 tons per day milling plant, would start operations. It may be noted herein that this first unit is the largest mill ing plant ever projected on any gold property in the world.
 During the year, which includes the winter of 1912, active operations to the ends mentioned above have been carried on in all three divisions and at the present writing the following results have been obtained and may be seen:
 At Perseverance.
 In the Perseverance division the roadways and transportation to the mine have been finished. The under ground development in the way of shafts, drifts and crosscuts is on sched- ule and is being driven on the bonus system at a high rate of speed. More than 300 men are at work in this department carrying out the develop ment plans of the engineers.
 On the outside, in this division, boarding houses, lodging houses, club house, compressor plant and all nec- essary equipment for a mining crew of from 500 to 75O men, are in process of erection.
 At Sheep Creek.
 In the Sheep creek division, the wharves, warehouses, roadways. din ing room, lodging houses, compressor plants, etc, necessary to the con- struction of this plant, are nearing completion, millsites have been cleared of timber and a crew of upwards of 200 men are actively engaged in carry ing out the details of constructing the camp and preparing the site for the steel mill and rock crushing plant. The construction on the latter will
