NUGGETS FROM THE HILLS.

Report is that a thirty-fve pound gold nugget was found few days ago
 near the Shelton mining group. The leasers of G. c. Waddell's N. A. N mine on Copper creek recently l. stripped sixteen tons of ore from that | min which has netted them $40 per ton in gold.
 Rain has fallen in the Mohawk sec 1 tion sufficient to fill the tanks and | harden the roads. During the fall
 large number of prospectors will be turned loose in the hills.
 ''We are on the verge of a great 1 mining era,'' remarked Clarence King, former chief of the United States ge- oiogical survey, to a Denver Republi- can reporter. "The time is not far distant when a man can start out of Denver and travel to Klondyke, stop ping every night at mining camp" The King of Arizona company is pushing along the work of develop
 ment and the outlook continues as promising as ever, according to the Star. The small mill at Mohawk pro- duces the usual amount of bullion and will be kept steadily at work un-
 til water is reached at the mine, when
 a large mill will be erected.
 Several good discoveries have been
 made adjacent to the King of Arizona
 claims. The Jenny Lind is located
 on a ledge that crosses the King at
 an acute angle. The ledge is about
 twenty feet wide with a four foot vein
 of very rich ore of the same character
 as that found in the King. The prin-
 ciple owner is George w. Norton of
 Mohawk. Other strikes are reported
 in the vicinity.
 With 100000 tons of ore In sight,
 the Treadwell mine on Douglas is
 land, Alaska, is soon to have the
 largest stamp mill In the world. It
 has been decided to double the ca pacity of the plant, making the num-
 Der of stamps 300. The next largest mill in size is located in South Africa,
 and has 2SO stamps. The Tread well will mine it's product at a cost of
 S1 a ton and will produce $125,O 1000 monthly.
 At Creston, Minas Prietas, Sonora, Mexico, the roasters and cyanide plant are treating 100 tons day, and are said to be the only ones adopt ing that method. The tailings are ullASu WILL ICtW SIdUo COnC0QLraIoS and then passed through the roasters with salt, in order to convert the sil- yer into chlorides. From the roaster the pulp goes on to the cooling tank, each tank taking 100 tons. Good re- suits are reported.
 Several recipes for cleaning copper plates have been published by Smith & Irving of San Francisco, who fur i nish the following: When copper | plates are stained with verdigris. | which prevents their amalgamating with and saving the gold, the plates | can be cleaned in the following man. ner: Thoroughly scrub the plates with fine sand and water, using coarse gunny sack or scrub brush. Wash off the sand and then scrub | thoroughly with a solution consisting of one part oil vitriol and four parts of water The acid disintegrates the verdigris, dissolving the oxide of copper, and leaves the plate clean. when it will readily amalgamate with mercury without the use of cyanide | solution, except the acid solution should have been made stronger than herein prescribed, in which instance the plate should be washed off with water and then dressed with a solu- tion of cyanide as usual
