U. $. IN THE LEAD
Development of Commerce
 in Twenty Years
4 Billion a Year Has Been Adde to 1t How the Growth Was Brought About.

Washington, May 21.-The underly ing causes of the wonderful develop ment of the United States during the past twenty-five years through which it has reached first place in manufac- turing in the family of nations, are suggested by a compilation recently prepared by the department of com- merce and labor through it's bureau of statistics, showing the production of the principal minerals at intervals from 1880 down to date in the United States and in the world as a whole. The commerce of the United States has increased from one and one half bil- hons in 1880 to two and a half billions of dollars in 1904, while the commerce of the world meantime has increased from fifteen billions to tventy-two bill lions, the relative increase made by he United States being thus greater than that of the other parts Of the world
 The principal mineral products en- tering into and forming the basis of industry and commerce are coal, pig iron, copper. lead, zinc, petroleum, and the precious metals, and in the pro duction of each of these the Cnited States has shown a wonderful develop menJ during the twenty-five years un Q der review. The worlds production of coal has grown from 33O million tons in 1880 to S66 millions in 1903, the growth being 536 millions. or ITO per cent: of pig iron the growth has been from IS million tons in 1880 to 46 mill lions in 1903, an increase of 2S millions or 155 per cent; of copper from 15i thousand tons. to 613 thousand, an in s. of lead from 233 thousand tons to SS7 thousand ir 1900, the latest year for which figures are stated the increase being 654 thousand, or 2S0 per cent and it's production of zinc has increas- | ed from 233 thousand tons to 565 thou i sand, an increase of 332 thousand, or l 142 per cent. Statistics showing the worlds production of petroleum are : available only for the years 1890 tC i 1903. Tn the first year named the worlds production of petroleum aggr,.- i Ea ted 14S million barrels of 42 gallons l each. while in 1903 it's production was i 195 million barrels.
 In each of these materials it will be l observed that there has been a con- siderable growth. When. however, ar
 examination of the production of these
 minerals in each couGtry Is made. Il . Is ODSSTNEu mat the Onlled oldIGS Dds
 contributed more than any other single
 country, and shows the most hapit
 growth. In 1880 for example, the Un-
 ited States produced 6S million ton:
 out of the total worlds production c | 330 million tons of coal, the share il the United States being 20 per cent; i in 1903, however. the United State: produced 319 million tons out of the i worlds production of S66 million tons the proportion produced in the United States being 37 per cent. In 1880 th' United States produced but one-fifti of the worlds output Of pig iron, the
 relative amount being 3.S million ton.
 for the United States and 1S.3 millioni for the world; in 1903 the United States contributed nearly 40 per cen
 of the worlds pig iron, viz: IS milliOI
 tons out of an aggregate of 46 million! for the entire world. The developmen
 of copper production in the United States has been unusually rapid. T. ] 1880 the United States produced 27,O0'
 tons of copper, or less than IS per cen
 of the world production; in 1903 tn 1 United States produced one half thu
 worlds copper output. her share being
 311,627 tons as against SIS, 3,129 tons fo the entire world.
