yECUTIVE COMMIT n
A RENLYAL IN INNING.

There is a great revival of the mining
 interests in Colorado and there is every
 indication that this renewed activity
 will spread to Arizona and other min
 ing sections of the west.
 Dwelers in Colorado for the past
 twenty years unite in the opinion that the prospects for the mining industry were never better than they were today, says the Denver Sun, and there has
 never been a time in the history of Col orado when the new districts opened
 up gave stronger evidences of continued
 prosperity.
 Mining camps of permanent charac- ter are not often developed in a month, or even year. It was two years after
 the first discovery of the value of car bonates before LeadviIe became what it has since remained, and when B. Clark Wheeler came to Leadville to cell town lots in his new town of Roaring Forks, just across the river from the present townsjge Ot Aspen, and pre- dicted that the mines of that district would rival Leadvlle, he was considered visionary. That was in 1890, and though the men who pinned their faith to Aspen continued to delye and open up the deposits which underline that wonderful camp, it was five years before the camp began to show any indications of the great mining center that it has since become.
 Twenty years ago the treatment of ores containing refractory elements in an economical manner was not gener- ally understood, and as a result, many districts known to be rich in the pre- cious metals were left uudeveloped; even where there was a minimum of the refractory minerals time was necessary to reduce the system of mining and re- duction to profitable basis. This has been greatly changed, and while much has to be learned and new discoveries are continually being made in the mat ter of the reduction of ores, there must be an unusual amount of stubborn qual- ities in an ore to cause it's rejection at the shelter, The result is that @ greater portion of the ore found is merchants able. That of itself is of a stimulus 10 the mining industry, causing the work ing of veins long since abandoned, the product of which assures a moderate profit.
 The changed cond tions affect the sw | camps by shortenin .he time of prcJa. l ton which they must necessarily m. dergo. But development work must still be done. A discovery i7 not mine, | for there are few prospects in which . the discovery shaft opens an ore body . sufficiently large to pay from the start. . Development alone makes a mine, and . while prospects are sometimes sold for handsome figures, large investors look for more than mere chance, for as the miner has it, "one mau can look as far into the ground as another"
 The fact, therefore, of such large sales as have been made at Creed, at Cripple Creek and at Copper Rock camps of only few months existance, in which the development is necessarily of the

Mining property is always sought for when backed wich something tangible, and il IS evident that the new camps have backing of no tritling charatcr'
