MINING SHOW IN NEW YORK
 IN FULL SWING
Exposition That Opened at Madison Square Garden on Monday Last Is Attracting Much Attention.

NEW YORK, May 3U.-An interna
 tiOnal mining exposition, the first ex hibitiOn of mineral and metal prod ucts and practical mining methods ever held in New York, has been in. stalled in Madison Square Garden. and, beginning last Monday, will re main open until June 30. Many dis tinguisAed mining engineers and ev-
 perts are among the promoters of the
 big mining show, and the United States government, through the ge- ological survey, has made an exten- sive display of it's mineral resources. The American Mining congress and several state governments and state and interstate mining bodies have also endorsed the exposition. Dissat- isfactiOn. with the management has caused some of the western states and mining communities. notably Utah, to refuse to make displays. but despite this fact the exposition Is fairly representative of the great mining districts of the west. Mining machinery in operation and a repro duction of a western mining camp form notable features of the show.
 The exhibition of the United States geological survey shows that about 75 minerals are found in the United States, ranging from coal to uIa. mOnds. Not many of the latter pre- cious stones have been found, but they were widely scattered, and as their locations and surroundings were similar to the places where diamonds are found in great abundance in South Africa. scientists hold out to prospectors the hope of finding Kimberly field in the New World
 That there is a wide field for the mining exposition to cover in this country alone, is evident from tae fact that the mineral production Of the United States increased five-fold between 1880 and 1906. or from s364.- e2S,g9S, tO $1,902, ,517 ,565. The latest figures of mines and Quarries show that there were 15,516 mines. qIa:- ries and wells in this country. To operate these, 619,4 ,4O6 men were kept busy at a total annual salary of $400. 100000. Such are the tremendous proportions to which the mining in dustry of tle United States has at tained since it's early beginning.
 The first recorded finding of iron within the limits of the United States was in North Carolina in 1885. The first effort to manufacture it Vas in Virginia in 1610. The first expOrt of bar iron to England was in 1717, and of pig iron in 172S. Until 1850 Mas sachusetts led in the manufacture of iron, when Pennsylvania took the lead. and has retained it. Over 4O,. 100000 tons of iron ore were mined Tn Michigan alone, last year. Next to iron, the most valuable mineral production of this country is copper. of which enough is produced annual ly to give every American man, wo- man and child g worth each if it were divided out. In Arizona alone the production oE copper in 1896 was s54,0O0,O00.
 One of the earliest finds of gold in the United States was referred to by Thomas Jefferson in his diary. IL was a lump O! pure gold. found on the RappanhaEnOck river, Virginia. Now many millions of gold are produced every year. The Cripple Greek dIS- trict in Colorado alone ias produced over s125,000. 900. In California's palmy days as much as S65, ,0O0 900 worth of gold was produced in a sin gle year. The surface of Alaska has only been scratched. but upwards of S6.OO0.h00 in gold is produced there annually. Alaska is said to contain the richest gold deposits in the world, the gold placer field in Seward benin sula alone containing 10000 square miles. The latest claimant for honors as a gold bearing. territory is the Ne vada desert, where fac mining camps of Tonopah, Goldfield, Bullfrog, Raw. hide and a number of others have sprung into being within the last few years. From that region is pouring a steady stream of the precious metal.
 If the scarcity of a metal is any indication q it's value, silver ought to be more valuable than gold, as the world is producing s400,000, 900 Of gold and only s100.0O0 900 of silver per annum. 4 large part of the American production of these metals is consumed by the United States mint. The coinage of tho Philadei. phia mint, last year. was s14S12S- 01l.93. not including 4J.000,000 pieces of ""iu that were miuted for Pauama. Mexico and the Philippine Islands The coinage for this year is expected to exceed that of last year by 20 per cent. Uncle Sam makes money by buying silver bullion at 56 or 57 cents an ounce. which is passed back to American citizens on a par with gold at tae ratio of s1.29 per ounce.
