THE MccRACKIS AND SIGNAL MILLS
 ON THE SANDY.

Hon. Thos- Coriis and Gideon Cornell Esq returned frsra Signal City, Monday evening and bring encouraging reports ss tc business in that part of AohAve county.
 Mir Cordis took mush pains to inform himself concerning the working and capac- ify of the naills, but had not time to visit the mines, consequently our interview with him has been confined exclusively to the mills. some account of which VIC here at tempt 10 give
 MicRAcKIy MIL
 The information obtained hy Mr. Cordis Wi.h refrrens,e fe this mill is b2-ed upon prrsoaal inspection of srery portion of the works, with liberal explanation by Nr- A. Batemzn, tho Superintendent, who afforded him every psissible opportunity to learn as much as possible.
 The engine is 1so-horse power. and drives with case % stamps, IL pans. . settlers, 2 steara pumps and a rock breaker
 The ore consisting of chloride of silver in friable spar enables them to reduce the enormous amount of 50 to s4 tons in 2i hours, and kr. Bafeman expects in the month of Anyil to increase is to 100 tons
 From the dizmp the ore passes over screens to the rock breaker, the fine matter that passes through goes through shutes directly 10 the self feeders while the broken ore from the breaker reaches the same reeeptieie by another route.
 There are four self feeders; one for each battery of five stamps The batteries arc double discharge, front and rear, and the pulp is conveyed from them to the tanks on the pan floor by means of troughs- Three large retorts are set in furnaces, and the pipes are covered with cast iron water jackets
 The quicksilver pump is a valuable assist ant in the work. taking up the quicksilver from the lower floor as it comes from the stlainers and retorts. and depesiting 1t again on level with the pans, thus avoiding the labor and waste of carrying it up by hand. In fact eTery new labor saving appliance knoxn to the business is here introduced, and the expense a.d time formerly expended in handling the material Is greatly reduced.
 Tn about month Mr. Bateman will com mence to remove the old Greenwood mill to a point below the McCrsek;n, on the Sandy, where. the assistance of a complete foundry. lsthes. etc. for making and repairing machinery, they expect tonake 1t first class mill
 On the esnd of March, Mir Bateman shipped nine bars. the result of four days run, the last ffty-tso hours of which pro duced S5.S00. He thinks that during the month of April he will turn out $s0.00o.
 The NeCzckin mill consumes twenty cords of wood per day.
 THE SIGNAL MILL
 Mir. Cordis also inspected the Signal mill personally and was accompanied by the Superintendent. Thos- Ewing, Esq, who ex- plained the ssodss ag<ran6i.
 The Engine is 1s0 horse power and drives tsn-sfzmps, SIX 5Is s-foot pans. three 9-foo' settlers. steam Snd cold sater pumps etc, all the latest sad hest improved make
 This a Il works S5 t0nS, on sn average, in q hours. has self feesers. two retorts set in furnaces: ssperzfe from the mill. the most complete assay office in the Territory. etc. etc etc.
 Mr. Field, formerly ofWells, Fargo& Co. San Francisco. is boss of the assay offce and book keeping department. The mill burns seven and a half cords of wood per day, the t-snsporfation of which costs from $S.oe to 5.7s per cord The contract price for trsss- porting ore from the mine 10 the mill IS $500 per zen. Twenty-seven men are al work in the mine and fourteen at the mill though much Of the dead work at the mine is done for the season, and the probabilities arc that the number of miners m the shafts and levels will som be reduced and the stopcrs retained, as they will then be able ts take out ore faster than the mill csn work 1t
