Hon. w. M. Griffith, of Tucson, GX- U. $. marshal of Arizona, in company with John w. Prout well-known mining expert, spent several days here last week examining the mining prop erUy in which Mir. Griffith is in terested. It was MT. Prout's first visit to this section, and he was greatly pleased with the district. He will return agaIn shortly and spend several weeks exam ming the district.

 S. $. Marshall has disposed of his group of mines in the Montezuma dis trict a St. Louis company being the purchasers. They have organized the Roland Mining company, Mir. Mar shall having attended to recording the articles of incorporation and filing a certified copy with the secretary of the territory. One of the conditions of the sale is that development work must begin at once and be prosecuted continuously.-Bulletin.
 John stanton says "There is every reason to believe that the price of re-
 fined copper will go considerably high | CT. Consumption is very heavy, and | production has not increased to any | appreciable extent. Much of the
 large surplus, which was held in this country six months ago, has been shipped abroad. The mills are work ing to their utmost capacity, and many | consumers are anxious tO know where the supply is coming from if consump- tion and production continue in the present ratio."
 It is pointed out by the mining edit or of San Francisco paper that only 25 years ago the ores that carried less
 than SIP per ton were regarded as be- ing too low grade to be worked at profit, and the cost of mining and milling was estimated to average about 80 per ton. Today, however, in these very districts, ore is being taken from a depth of 2OO0 feet, and mined and millcd at cost of g. 25 per ton, leaving handsome profit, though the ore only carries $4 per ton in gold.
 The Yaqui Copper company of which Mir Wm. c. Greene is president aud Col. w. P. Harlow is vice pres- dent and general manager, own near the Yaqui river in sonora, Mexico, copper properties which in magnitude ar seec md to none. Mining experts, practical mining men, and indeed all others who have seen this vast deposit concur in the opinion that it is capa. ble of development to degree that would affect the price of copper in all the markets of the world It is the intention of the company to i'm. mediately commence .he working of this property on large scale.-Border Vidette.
 In December 1901, about 1000 stamps were running in South Africa, out of total of 5000 head. The Chamber Of Mines anticipates that five years hence some F, 900 stamps will be running. This is nearly three times the present. total, and the question necessarily fol- | lows. Does this mean three times the production made when the 5000 head were dropping? The production then was close to $l00,000,00 900 annually. | Three times this amount means the enormous production of $500, ,000, GOO. | Here is something to figure on for the | experts in gold and it's probable over | production, on,-Journal for Investors.
 Some months ago the inauguration of the steam shovel at Mayer was at- tended with open expressions of'dis- regard by the average miner, but to- day the opposite prevails. Under the supervision of William Lester of the Mayer Placer company, who was the first to introduce this method of hand ling the soil of Big Bug, there has fol- lowed his efforts successful and con- tinuous run, and now after five months of steady operation he pub licly states that the machine handles the ground satisfactorily and the ground yields prohtably. A novel feature in connection with the enter prise not generally known, is that the creek bed is not worked, but the mesa or table land adjoining is mined The soil is gravel in some places and is in adobe. The latter car ries the yellow metal, and through the mechanical genius of Mir Lester he now has machine that handles this commodity that has heretofore baflied similar projects. So success ful is this steam shovel that four more have been ordered and will be put to work on adjoining ground. Prescott
