Much Labor Saved.
 Under the old method, it was GUS
 tomary for from twenty to fifty mel
 to handle this ore, and little, if any
 headway could be made in its tran
 sit. The ore, also, was so. ground uI from repeated shovelings that it wa
 not in fit condition to be placed il
 the blast furnace, because of it
 crumpled condition. With the later
 device of MT. Bennetts, the ore i.
 not handled once during its entire
 transit from the receiving bins tC
 the furnaces. The sampling mill ha:
 been entirely redesigned and rear
 ranged, always with the object ir
 view of using the machinery and
 equipments already on the ground tc the best possible advantage, one fea, ture in particular being the electrical controlling device, whereby the two units of the mill are operated inde. pendently of each other, at the same time permitting the instantaneous shutting down of the mill from any of the four floors, in case of acci- dent.
 The storage bins are provided with swinging steel chutes, which serve to charge cars, the latter being hauled by electrical locomotives to the re- verberatory and blast furnaces.
 The blast furnace is of the very latest type. It is 4sx17O inches at the tuyere level, and was built by the Power and Machinery company of Cudahy, Wis. It has a blasting ca pacity of $50 tons a day. Provision has been made for the installation of a second furnace of the same di- mensions, as the officials of the new concern are confident that there will be need of another in the near fu- ture. The air necessary for use in connection with the furnace will be furnished by a mammoth Root blower. This blower will be one of the largest in the territory, weighing when com plete, 10000 pounds.
 Some adequate idea of its capacity may be had from the fact that 1t furnishes 16,5OO cubic feet of com pressed air a minute.
 The blast furnace building has been entirely reconstructed of steel, the charge floor being laid with cast iron plates made at the foundry re- gently erected at the shelter. An other revolution in the operation of the blast furnace, is the way the coke is now handled. A standard gauge railway track has been laid on an in- clined trestle, which permits that reg ular railroad cars carrying coke may be run right up onto the charge floor and the coke dumped there, which obviates the former method of shoveling and wheeling iU up to the top. The reverberatory furnaces, which are among the largest in use being in dimension 20x100 feet, inside measurements, are being overhauled, and up-to-date charging installed.
 Another important feature is the of the heat from the waste gases. The throat of each furnace is being enlarged, and a complete sys- tenn of large flues, built of brick and steel, are now under construction. These flues, together with the balloon flue from the blast furnace, lead di- reetly into a gigantic brick stack. 200 feet high. The stack is twenty feet in diameter at the base, and twelve feet at the top. It is of Ger man make, and one of the most mod ern in type. At the flue-end of each a battery of Sterl- l ing water tube boilers are placed. | These boilers were on the ground when the new company assumed con trol, but were in such a position that | it was found necessary to move them l distance of some 300 feet. This | was accomplished by the erection of | T large cradle-carrier, capable of sus- -aining one hundred tons weight. It | was then fitted up with a set of tim Der rollers, and the work of skidding | begun. It took week to effect the | but the boilers are now in ! much more advantageous position. The steam generated in these boilers IS piped to the power house on the grounds, which has a 1000 horse | power electrical generator. This power is then transmitted to the Blue Bell mine, sixteen miles away, and is also used for other purposes right at the plant.
 New Water System.
 A complete new water system has also been put in at the works, and the workings of it are of great me |
