Colorado has exceeded every other section in the growth of her farming industry. This growth has been phenomenal. In 1880 the State imported 500,000 bushels of wheat, 2,000,000 bushels of corn, 500,000 bushels of potatoes, 1,000,000 bushels of oats, and 100,000 tons of hay. Last year there were produced in the State about 10,000,000 bushels of cereals, and instead of importing, the State exports; and in eastern markets Colorado wheat and oats command a premium. So great has been the development that authorities on agriculture assert that the agricultural output exceeds that of mining, which assertion is contradicted by mining people. But be this as it may, no other section presents a parallel to the rapid advance of agriculture in this State. One-half of the 66,880,000 acres of land in Colorado is estimated as agricultural land, of which 12,000,000 acres can be turned to the plow. There are now 2,000,000 acres under cultivation. The remarkable feature of this progress is the success attained by the "rain belt," which only a few years since was considered irreclaimable land. All over the State farming has been profitable, and by the contiguity of markets prompt returns for the products are the rule. This has induced immigration, and is one of the contributory causes of the influx of settlers into every section where cheap lands may be obtained. IRON.--The largest deposit of iron in Colorado is in Gunnison County, and when taken in connection with the fact that in this locality cheap fuel abounds, it is a deposit of magnitude unequaled anywhere in this country. By this fortuitous combination of deposits, No. 1 Bessemer pig iron can be produced at Gunnison for a cost not exceeding $12 per ton, or 50 per cent less than the price at Pittsburg. The deposit is near Sargent, on the Denver & Rio Grande Railroad. With an outcrop that is enormous and high in grade, it extends at intervals for a mile on the mountain side. A number of openings have been made, one of which is a tunnel run across the vein ninety-seven feet and an open cut exposing a face of forty feet all in solid iron. There are about fifty acres in the five iron claims which compose the White Pine deposit. There are iron beds on Gold Hill and Cebolla rivers. At the latter place the iron lies in an immense ledge of unknown depth. Iron abounds in other portions of the State, especially in Chaffee County, where the Colorado Coal & Iron Company of Pueblo have been drawing material for the manufacture of railroad iron, merchant bar, and steel. Iron and steel can be manufactured as cheaply in Colorado as in any other section of the United States, and the advantages that contribute to the State's superiority in this respect are the increasing demands, which can not be affected by the overproduction of the East and South; no rival point west of the Rocky Mountains claiming competitive facilities and an advantageous position as the geographical center of a vast territory; an
