 FURNISH WASTE
 FOR MANY FILLS
Great Mountain Will Be Dis tributed Well Over District as It Is Removed by Steam Shovel Operations

When a mountain is being blasted and dug out of existence for the sake of the copper it contains. it is certain to produce a vast amount of waste material. Where. asks the average Bisbee man, is the mOnstrous tonnage of waste from Sacramento hill, which is being relieved of overburden by the Phelps Dodge Company, as a prelimin- ary to steam shovel operations, to be dumped?
 The answer was not hard to find. The disposition of waste from the hill already has begun to be a problem and the company has set to work to find A solution. It has built switeh-baeks allowing waste to be dumped near the Spray Shaft. When that depression has been filled. a switch-back from a point near the Shattuck landing will be installed. This will allow addition al waste to be dumped on top of the ether which already had been piled in to the valley near the Spray, or add an upper layer
 When the thousands of tons of waste necessary to accomplish this fill have been thrown in and it becomes physi- cally impossible to place more of 1t around the Spray. still another switch back will be laid. allowing trains to 20 to a small basin above the Hoatson shaft. This again will require a lot of material to fill in.
 More railway trackage then must be laid to get another switch back over the saddle toward the Dallas property of the P. D. company. a prospecting shaft, not now in operation
 With the latter fill. all of the waste from above the level of the old ma chine shop will have been disposed of, according to the calculation of the engineers. However, quite a good deal will remain below that point to be got ten rid of
 Just where this waste will be dump ed has not been decided, though sev- eral plans are under contemplation. One would call for the installation Of trestle from Sacramento hill, across Naco road and into Copper King can yon. just west of the old Copper King shaft. Another plan tentatively pre- sented by the engineers would be to make a vast fill near the residence Of Walter Douglas at Warren. Still an- other calls for a dump below the com pany mill site.
 There will be plenty of time to de- eide. however, as the top layer of the hill is proving stubborn and the ma terial is harder than ordinarily is at tempted to be removed by steam shov- els. This means, of course. that giant loads of powder must be employed to break up the capping-
 It is the cOmpany's expectation that within six weeks the top will have been removed and work then will be able to proceed more rapidly in the softer material.
 The overburden thus far removed has not been mineralized to any great extent. Some stringers of ore which had not been expected have been found. but not in any considerable quantity.
 It will be several weeks, at the least calculation, before sufficient quanti- ties of the upper ledge have been re- moved to allow of removal of rock sui ficiently mineralized to run through the company mill. to add its quota o4 copper to the metal being sent con- stantly to aid Uncle Sam in fighting | his war for democracy and civilization,
