ing, and there is a tree which has never been cut because it served a. the hangman's tree when justice de manded a life for life. The office building, the boarding house. the as- say office are built of stone-and this stone came from the mine. If these houses were demolished now it is probable that this rock would run an average better than SI00 a ton The highest hill for half a mile round Is that made by the waste from the mine. The mine stands just on the edge of a mesa which overiooks a stretch of 70 miles one way and 15e another of the Great American Des- ert, where there is no water and where 1t is impossible to sustain life without carrying food and water-but where, it is declared, within a few years government engineers will have changed everything by developing wa ter at a distance and turning it onto this fertile soil; when the farmer will come and transform it till no one will believe 1t ever was other than 8 land of plenty and of comfort
 The Vulture mine of today is diff. ferent rom the old mine in every way. It is of course lower grade
 There is one of the most up to date
 20-stamp mills here to be found in the southwest, and cyanide plant extracting 90 to 96 per cent Of all val

 with the greatest comfort. Daily mails are receiyed-in fact every com fort of the modern mining camp is here. Instead Of ''gopherins for the
 high grade the mine is being proper
 ly developed to depth, work being now below the 700 foot level, on the
 incline of the vein. The new mil is equipped with i50O-pound stamps
 Where ore running less than S5t would not pay in the early days there
 is now a plant which ean operate to a profit on S5 rock-which tells the
 story plainer than great many words could
 The Vulture deposit lies in schist
 which is scanned with quartz and of ten-times very highly silicifed. There are occasional intrusiohs of porphyry The country itself is granite, some times very greatly changed. The vein is east and west. dipping to the north. A winze is being sunk from 1 the 700 which is to be continued down 200 feet. With this considerable depth there is no change in the de posit, and no pinching of the vein. ] The ore comes in lenses, or shoots, and sometimes here as always there are days when the machines will work without ore but this is seldom. The average of the ore could not be ascer 2 tained,. but l judge that it will run above $5 per ton. There are two shafts. through which operations are | constantly forwarded, each being well i equipped with hoist, etc. The ore is l brought to the surface in l-tCn skips i when 1t Is transported by tramway | to the mill, where it is dumped into | bins, then through a crusher, then l oyer grizzly to the stamps, 5-inch droI | 3-inch discharge, through coarse l screen, 2-l6 inch.
