the earliest located in that section and the surface produced lots of rich ore. Mir. Clark opened them up to some depth and built a mill and worked the ore from the mines until his interests in the east became so ex- tensive that he could not look after these mines and they have been per mitted to lie idle ever since. When he quit work he had five feet of good ore in the lower levels of the develop ment and the ore taken from it plated S4000 per ton. Like other mines in that section, the claims comprising the Chicago group have produced wonderfully rich ore on the surface, Some of the richest ore in the district having been found in them. Like the others also, there is reason to believe that the ore extends down and that when the mines are worked his tory of that district will repeat itself and that the deeper they go the rich CT the ore may be expected. It is the intention of Mir. Clark to resume work on his property by either clean ing out and retimbering his old shaft or by sinking a new one to connect with the drift of the old workings.
 Judge S. w. Purcell yesterday com pleted deal with Dr. G. w. Lenox and G. w. Rice for eastern parties by which the Tres Amigos group of gold mines passed from the ownership of s. w. Champion. The consideration is on the basis of S50,000. Work is to be resumed on larger scale and the mill now on the ground is to be in creased. The Tres Amigos is one of the large gold mines of the territory and has had a phenomenal growth. A few years ago the prospectors found a rich pocket of ore in what they thought to be porphyry, but upon examination it proved to be a quartz ite ledge. Over 5000 was shipped from this pocket. Mr. Francis Me masters shortly after this strike pur chased the property for Mir. Cham pion. Mir. Macmasters took the gen eral management of the property and began at once to open 1t up to the best advantage, and at present the workings embrace shaft l15 feet. This shaft is connected with a tunnel 750 feet in length and an intersecting tunnel $50 feet from the mouth. From the tunnel 130 feet four crosscuts are run to the northeast to the foot wall showing vein thirty feet wide. At the mouth of the tunnel the ledge Is fifty feet wide. Another crosscut is made at 125 feet from the mouth of the tunnel showing vein twenty five feet wide. Four other cross cuts were run to the foot wall showing vein twenty five feet in width. At the mouth of the tunnel winze is sunk on the ledge eighty feet and a drift run from this 100 feet othe southeast line of the claim, and another drift 100 feet north. At this point in the workings the ore is POO feet deep from the apex of the ledge. l25,000 tons of ore is now exposed in the tun- mel, and there is said to be 1000 tons of milling ore on the dump. The outcrop shows the ledge to be strong and from twenty five to sixty feet wide, passing through the Tres Ami gos and San Juan claims (the latter being one of this group .)-Tucson Citizen.
 The production of precious stones in Arizona is sooner or later to build up an important industry. There are many of the finest gems in the world to be found in this country, such as the turquoise, sapphire, garnet, ame thist, ruby and many other gem stones that could be handled by local lapidaries. The turquoise produced is of the finest color and texture and brings the highest prices in the mark cts of the country.
 John Lawler has gone to the Hill side mine. It is stated that work will be commenced shortly on this prop erty again, and shaft will be sunk to a depth of at least 800 feet. Most of the development work hereto fore done on the property has been done by tunnels. The owners are'no determined to ascertain what they possess in the lower depths of the mine.
