 Tbis does not give the expense of hardware or other small fiNngs about mill, which we never estimate upon.
 The following is the price of 10 stamp mill, got up by Mr. James Brodie, an engt- ncer who has an office in San Francisco. and attends to the getting up of plans and spccif- cations of mills, and also to the superintend- ence of the estimates and foundry work. He has also plan of relieving the stamps from the crushed ore, by suction fans, patented by hun, and which Is working very successfully in dry crushing mills.
 Where the rock has to be roasted I think this is the best plan:
 1 One 10 stamp mill batteries made suita- ble to extend to 2O stamps; shafting and en- | zine of sufficient power; c Wheeler < Land al's pans, and separators; 3 sets of furnace i irons for roasting furnaces one steam engine, : l6 cylinder, g feet stroke; ? boilers, II feet long, 4G inch diameter, 5S fines, inches diameter, with all the necessary mounting | One retort for l, ,OO0lbs. amalgam. The whole of the above, ready for shipment, for the sum ' ui Sl1, 10000, Federal tax not included
 This appears 10 be high, in comparison with the other mill it is the difference be. tween dry and wet crushing mills The next mill is one sent to Mexico, foi wet crushing:
 10 stamps of batteries, made in sections for convenience of packing; spare sets of shoes, and spare sets of dies Wheeler X landaPS pans, to c inch diameter, in sec tions; $ Wheeler & Landal's settlers; of Praters' concentrators boiler, g inch di- ameter, feet long, for heating water for pans, with pump-cocks and pans all the sbaitug to drive the machinery, and to con meet to , feet turbine.
 One .Ionyal turbine for % feet fall. with draft-pipe and shaiting, Sl 900; retort for l,oo0 lbs. amalgain, S23O
 The whole of the above, ready for shipment and made in sections, none to exceed 300 lbs. for the sum of Sl0O00
 These three mills give you 2 good idea o what mills will cost; but every engineer re 1 quircs different arrangement of shaft ing, etc. And in this Is the>diference in the price of mills. As genef4 thing stamr mills weigh from l 800 to 2 ,Oo0 Gbs. per stamp and can be got up for 9 to 9l5 cents per ID. Hepburn < Peterson's separators cost S3S0 and weigh about 2,100 lbs. Shalting pullie. cost from IL to lG cents per l6.. and weigh according as the mill is laid off Enginfy and boilers of the class sent to quartz mil 9weigh about $50 to 600 lbs. to the horse-pSyer. one set oi furnace castings weighs l .45e lbs. This, l believe, contains data enough for you to form appropriate calculations upon which l understand is what you want. From what l can learn from parties bring ing machinery from New York. it is more expensive than getting it direct from San Francisco, and, however much may be said about New York machinists working rran, the same drawings, and making as good q job, or, that they can build quartz mill as good as we in San Francisco can, it is not sa There has not been a good mill, that have seen, come from the East-always something wrong
 Cost of freight to Reese River, from & to l2 cents per lb; tbe rate now is l0ls cents per lb. From the first of June to the first of August, cents.
