WASHINGTON AND DUQUEsNE.

WASHINGTON AND DUQUESNE. About the time Of the discovery of
 Leadville, or so soon thereafter as the
 extent and value of the rich carbon ate ores there found had become gen.
 orally known, the discovery of large
 and extensive bodies of very rich ores
 of the same variety at Washington
 Camp. about twenty miles east Of
 Nogales, and four miles north from
 the international line, attracted great attention, and for a time tnere was
 quite a boom in property in that vii cinity But when a slight depth was
 attained the character of the ores changed to a very rebellious rcck rich in copper but carrying much zinc and sulphur Many properties which the original locators had sold for hand some sums were abandoned, while other owners, looking for the future, secured patents to their claims, regu- larly paid their taxes upcn the prop erty and awaited the flight of time. Others clung to their properties, kept up their assessment work, and by sorting out and shipping some of their richest ores have contributed to the cost of development.
 Modern methods for ere reduction have evolved processes by which these rebellious ores may be profitably worked, capital has been enlisted and it is understood that extensive reduc- tion works will be erected in the near future by at least one company.
 The most prominent properties in the district are those of the Duquesna Mining company at Duquesne, a cor poration of Pittsburg, Pa., having un- limited capital and the utmost con- fidence in their well developed prop critics. This company, under the ca pablo management of MT. S. Teb- bets, ably assisted by MT. George J. Troop, superintendent, has one of the best appointed and most completely arranged plants for mining work any where in Arizona. The hoist has a capacity for sinking 1000 feet, and the boiler, which is magnifioently set in solid granite masonry, completely enveloping 1t, to the great retention of heat and saving Of fuel, is of suffi cient power to permit addition of an other drum and engine. The assay office is first class in all its appoint ments; the machine room, ca pentsr shop, etc., are all first class in every particular, and everything is put up on a scale capable of the most effect i've work, while the capacity can be greatly increased at very small cost. The main shaft is now down to depth of over three hundred feet. A great extent of development work has been done below, and the various levels cut the extensive ore bodies in all directions. Many thousand t7ns of very rich ore are now upon the dumps, awaiting the erection of the projected reduction works, and It has all been taken out in development work, not a pound Of ore having yet been stopped, while many thousand tons are blocked out in the mine ready for stoping when wanted. Recently the shaft has been widened from single compartment to three, and that excellent work was completed two weeks ago.
 Some months ago a shipment of 2jO tons of ere from the Duquesne group was made to Pittsburg, where most exhaustive tests were made of all the various processes of reduction for ores of that description, to determine the most successful and economical in ac- tual working. It is understood that the method which will be used has been decided upon, and that at very early day the necessary machinery will be upon the ground and in pro cess of erection. MT. Tebbets IS ID daily expectancy of being summoned
 fhn shipment of the necessary machinery
 Not far from the Duquesne property is the Holland mine, owned by a re- duction company operating extensive works at Canon City, Colorado. MT George w. Grove is superin. .endent of the proerty. The ore is hauled from the mine down to the mill and there concentrated for shipment. Gates crusher, Cornish rolls and two Wlhey concentrating tables with the neces- sary boilers and engine for power constitute the machinery, which re- duces about thirty tons of ere daily. At Canon City the works save all thsIF is on the rock, not only the lead, sll- yer and copper all being extracted, but the zinc also is saved and con- verted into paint.
 The Pride of the West mine, the property of N. H. Chapin, Frank Oi- sen and J. Nevill, is a steady ere ship per. and has been for fourteen years. About forty tons are shipped monthly yielding a net return of about $15 per ton. A shipment of about forty tens will shortly be sent to the Hearst re- duction works at Silver City, New Mexico. Eastern capitalists are. now negotiating for the property, and deal is likely to be made at any time.
 The Belmont mine is a very promls- ing property, not very far from the Holland. It is under bond to MT. U. K. Franklin of Denver, who has re- gently succeeded in organizing a com pany to work the mine on an extan- sive scale, and is now daily expected from the east to begin operations.
 The Poole group is very promising one of seven mines, the property of MT. David Allen. Like all the other properties in the vicinity the ledges are wide, thoroughly mineralized and carrying ores of very high grade. In
