the tables are of the Frue Vanner pat tern, except three, which are of the new Standard type. Los Angeles make. The tailings are sluiced off into
 bins, where they drain off their watc. and are wheeled into a drying yard and
 spread out to dry in the sun. From this yard the tailings are scraped by team
 and slip into a feed trough which leads into the roasting furnace, where the sulphides and other combustible ma terials are roasted off.
 This roaster is built in the form of
 an ellipse, one end of which contsittue> the oven The oven is of brick, ana built similar to large bake oven with 2n arched top. 1t is supplied with
 ports for draught and inspection, and oil is used as a fuel. The oil is spurted into the chamber through specially
 constructed nozzles. and is played in q long flame over the tailings, as the fuel is forced in under pressure. The
 oven is some ten feet wide and 200 feet in length, and these burners are dis tributed along the distance at short in- tervals. The tailngs are dumped upon the floor of the oven at one end, and are wo1 ked slowly around by a rabb;>
 arm fitted with small blow shares, which run through the material, turn ing it over and dragging it slowly along. This rabble arm is fitted to a | carriage which runs on two tracks, on- on each side of the oven, and blows about six inches deep into the tailings. The material is thus thoroughly turned | and roasted throughout before issuing ! from the oven. It is worked slowly out into the unroofed portion of the fur l mace. where it is air-cooled for some ] 300 feet, and then cooled by sprinklin- | water over the surface. The roasted
 product is rocked into a bin by the | rabbles. which are operated by an end less cable running around the furnacs, and is wheeled into the cyanide tanks
 and there undergoes the cyanide treat | ment. There are seven of these 10O- | ton tanks. some. of steel and some or ! wood, and six are in commission, whiis
 one is being empded and re-charged.
 The solution is run in at the top of d | filled tank and allowed to percoiate
 down through the mass. and is drawi. off at the bottom and piped to the zinc room. Here it is put into the zin. boxes and the gold collected and re- | fined and cast.
 The concentrates from the tables ar. !
 shipped to the smelter at Fl Paso.
 where they are smelted and the goNa | bottoms refined and cast About o7 ! per cent of the values in the ore D
 saved by this treatment of the con- ! centrates and tailings, which is fairly | thorough work.
 Is water is at a premium the water
 used in the boilers is run into con- l
 again, as is also that recovered from ! the tables at the mills. Tn all about
 S. per cent of the water is used over
 again. requiring a constant supply Of
 only 15 per cent of the total amour, used to be pumped. The water is fairly
 pure and good for household purposes. The families at the camp are charged
 slG0 per month for their supplies Tne
 fuel used throughout the, camp. at the
 hoists. the power station for the mills
 and at the roasting furnace is crude
 oil which is shipped in storage tanks
 to the works. This kind of fuel s,
 easily handled and requires less ex- i pense in maintainance of machinery
 and compares well with coal in cost in i this part of the territory owing to the.
 excessive freight charges on the latter
 The camp has population of some | l,5OO and is withal a rather lively place. The company has just complet- | ed a building in which will be housed
 the store and general offices. The
 store occupies a brick 100x5O of two
 stories and a basement and does a brisk trade supplying the miners with gener.
