Description of the Famous San Do-
 .ningo Plac:r Region.

San Domingo District, Yavapai coun- tya Ariz., Dec. 19.-(Special Cores t9endence of The Republican )-Placer mining has been carried on in this dis trict for years and the amount of god taken out is variously estimated. An cid Mexican miner, when approache ca this subject said that there wer' hundreds of miners working in tht San Domingo diggings in yeas gont by where there are but a handful to- day. The output of gold, he said sometimes reached $1O,000 a day durini the palmy days of these digging Nuggets worth hundreds of dollar. Were found in the gravel which als contains the finer gold. The long, nIr- row trenches and the great dumps c. boulders show the activity that on day belonged to this old camp.
 At the present time there are bIt small nupr,ber of men at work in tn San Dcihingo diggings. They are us ing .he same appliance for eXtractin' tb . gold that was used from the start he dry washer. It was only V heT there was an unusual supply of Tate' in the Eassayampa river, ln1 Iic- streak of ground warrantel hauling tn gravel to the river, that the gold was secured by the wet process. The hls .rict is about three miles from th Aassayampa and is located on what known as San Domingo wash-a grea gulch into which the mountains hay dumped their gold as time released from the veins and deposits.
 The boom in copper has taken tn prospectors out of the placer digging and sent them into the hills in searci of that metal. They only return to th' placer grounds when they need mor' mon sy to buy grub. This portion of th' territory is rich in surface copper, anc Some excellent prospects have beer discovered recently. The prospector is encourag ged by the efforts of the stronger individuals and companies who are sinking upon leads to de termine their value at water level. UI to the past year there had been scarce iy any depth gained in the district Mining men who were searching for mines found here only prospects Where the indications were especially promising capital went in and began to sink. In a year the Whipsaw has been developed, the Jones is 300 feet in copper zone. the COpperOpOlis is fast reaching its zone of enrichment" and there are other properties which give promise of becoming mines before the winters work is finished.
 In the San Domingo district Messrs. Williams and Nagle are working quartz gold claim and are taking out ore. The high grade ore is being ship ped to the shelter and the low grade is milled at the Trilby works. The Trilby is being worked with a reduced force of miners. A carload of concen- trates was shipped from this mine early in the week. J. H. Costello. of Cobre Grande fame, is the owner of the Trilby. He has other properties under bond in the district which are being developed. The TIilby mill will start soon on a six months run of GUS tom ore.
 Eerggreen and Harrison have struck a copper vein close to the banks of the Hassayampa river from which they are taking out ore for shipment. The Northwestern Coppsr company is also taking out shipping ore. On the Has sayampa close to Hot Springs junction W. T. Smith of Phoenix has a cyanide plant in operation upon the tailings dump of the old Vulture. He has seven tanks and is crowding the capacity. The tailings are said to be profitable.
 There are three men at work at the Garcia property under the direction of President Fitzgerald. A depth of three hundred feet has been attained on this works are new and of modern design.
