TIN IN THE BLACK HILLS.
Large Deposits to Be Found in the
 South Dakota Mines.
SOON READY FOR THE MARKET.
Ore That is the Richest and Easiest
 Worked in the World.
Samuel Scott, of Dakota, Talks of American Tin Mines-What
 Protection is Doing.

Mir. Samuel Scott, of Rapid City, South Dakota, was in the city yesterday on q flying business trip, leaving on last evenings train for Elko, New, and thence back to his home at Rapid City.
 MT Scott is practical mining man, and is interested in tin fields, for which the Black Hills are becoming noted. To REPUBLICAN reporter he talked very enthusiastically of the rich discoveries near his home.
 That tin in almost inexhaustible quantities exists in the Black Hills has been demonstrated long ago he said and in few weeks time it will be on the markets in the form of ingots. The reduction mill is now in process of con- struction and will be in operation by April 1. The mines lie in Custer and Pennington counties, around the base of Harney Peak, and there Is lots of it. The development of these mines rests in the Rapid City Land and Improve ment company, with an authorized capi- tai of S6, 900, of which Mir. E.. E. Byington, Allentown, Pa., is president. The company owns sixty-twot tin claims,
 
 Brown, Tin It'll, Margaret, First Find, General Grant, and Lu Lu tin mines !; 24l acres of placer ground, and two water rights near Harney City; 464 acres of land in and adjoining Rapid City, and much other valuable property.
 "The group of sixty-two tin claims owned by this company are located at Harney City, twenty miles from Rapid City. They are regarded by acknowl- edged authorities to be the largest and richest group of mines in the world.
 "Tin mining as an enterprise in the United States is destined to be one of great importance in the next century, and during the next five or ten years the foundations of immense fortunes will be laid in this industry.
 "rhe Black Hills will yield vastly larger returns in this industry than any other field on earth. Many of the veins here are from fifty to 300 feet in width, large amount entirely above ground, and can be quarried instead of being compelled to resort to deep mining. New and improved machinery and methods can be employed which will yield large returns quickly. In Corn wall many of the mines gave no prom ise unti! great depth had been attained, and at their best the veins were but seams of from SIX inches to five feet, and even then the ore yields but frac- tion of the percentage obtained from the ores of the Black Hills. Again, the nec- essity of handling the water met with in deep mining generally is matter of serious consequence in the Cornwall mines. This will not be question for consideration in the Black Hills for many to come. The impurities of the British ores is another serious mat ter. Their ores are refractory and have to be calciRed before smelting; they contain wolfram, arsenic, sulphur, iron, and other impurities. These must be concentrated with the black tin, and of course, at an added expense. The ores of the Black Hills are free from these impurities. The cost of labor in the competing mines is about equal, for while the labor at Cornwall is much cheaper one miner in the Black Hills is equal to two men in the mines of Corn wall"
 Mir. Scost spoke enthusiastically of the prospects of the mines now being worked. It has been calculated that any one that yields ten pounds to the ton will pay handsomely, and the assays of the mines owned by the company average much more than this. Ample ! railroad facilities are now available, | and, as MT. Scott remarked, "the l croakers against American tin manu- facture will soon have to pull in their horns v
