$532,314,117 in 1908; and to 480,363,424 tons, valued at $614,798,898 in 1909. Pennsylvania produced three-fourths of the total output of the country in 1860, and since 1900 slightly less than one-half. Up to 1870 there was more anthracite mined in Pennsylvania than bituminous in the whole country, but since that year the production of the latter has become vastly the greater, the totals in 1907, in which year each stood at its maximum, being 83,268,754 and 332,573,944 tons respectively.

Inasmuch as the present production is not considered locally—and with more or less justice—as at all indicative of the wealth in coal of the respective states, it may be said that according to estimates of the Geological Survey the following states are credited with the deposits indicated of true bituminous coal, including local admixtures of anthracite, the figures being millions of short tons: Colorado, 296,272; Illinois, 240,000; West Virginia, 231,000; Utah, 196,408; Pennsylvania, 112,574; Kentucky, 104,028; Ohio, 86,028; Alabama, 68,903; Indiana, 44,169; Missouri, 40,000; New Mexico, 30,805; Tennessee, 25,665; Virginia, 21,600; Michigan, 12,000; Maryland, 8,044; Texas, 8,000; Kansas, 7,022; and Montana, 5,000; with lesser deposits in other states. At the same time there are estimated deposits of sub-bituminous coal, isolated or mixed with bituminous, amounting to 75,498 millions of tons in Colorado (which is probably the richest coal area of the country); and in other states as follows: Wyoming, 423,952 millions of tons; New Mexico, 132,975; Washington, 20,000; Montana, 18,560; California and Oregon, 1,000 each; and lesser amounts elsewhere. Finally, of true lignite beds, or of lignite mixed with sub-bituminous qualities, the states of North Dakota, Montana, Texas and South Dakota are credited with deposits of 500,000; 279,500; 23,000; and 10,000 millions of tons respectively. But it is to be remembered that the amount and the fuel value of both the lignite and, to a lesser degree, the sub-bituminous coals, is uncertain to a high degree.

Petroleum, according to the report of the National Conservation Commission in 1908, was then the sixth largest contributor to the Petroleum. nation's mineral wealth, furnishing about one-sixteenth of the total. Oil was produce in 1908 in sixteen states. This productive area is divided by the United States Geological Survey into six “fields” (in addition to some scattering states) with reference to the quality of oil that they produce, such quality determining their uses. The Appalachian field (Pennsylvania, New York, Ohio, West Virginia and Tennessee) produces oil rich in paraffin, practically free from sulphur and asphalt, and yielding the largest percentage of gasoline and illuminating oils. This is the highest grade crude oil produced in the world. The California field produces oil characterized by much asphalt and little or no paraffin, and low in volatile constituents. The Lima (Ohio)-Indiana, the Illinois, the Mid-Continent (Kansas, Oklahoma and northern Texas) and the Gulf (Texas and Louisiana) fields produce oils containing more or less of sulphur and asphalt between the extremes of the two other fields just mentioned. The geological conditions of the different fields, and the details of the composition of the oils yielded, are exceedingly varied, and their study has been little more than begun.

In 1859, when the total output of the country is supposed to have been only 2000 barrels of oil, production was confined to Pennsylvania and New York. Ohio, West Virginia and California appeared as producers in 1876, Kentucky and Tennessee in 1883, Colorado in 1887, Indiana in 1889, along with Illinois, Kansas, Texas and Missouri, Oklahoma in 1891, Wyoming in 1894, and, lastly, Louisiana in 1902. From 1859 to 1876 the Appalachian field yielded 100% of the total output of the country; in 1908 its share had fallen to 13.9%. In the same period of 50 years the yearly output rose from 2000 to 179,572,479 barrels (134,717,580 in 1905) and to a grand total of 1,986,180,942 barrels,[1] worth $1,784,583,943, or more than half the value of all the gold, and more than the commercial value of all the silver produced in the country since 1792. The production in 1908 exceeded in value the output of both metals. Deducing from the figures of production since 1859 an equation of increase, one finds that in each nine years as much oil has been produced as in all preceding years together, and in recent years the factor of increase as been higher. So rapid has been the extension of the yielding areas, so diverse the fate of many fields, so shifting their relative rank in output, that the outlook from year to year as regards all these elements is too uncertain to admit of definite statements respecting the relative importance of the five fields already mentioned. The total output of these, it may be stated, from 1901 to 1908—uniting the yield of the Illinois to the Lima-Indiana field (since their statistics were long so united, until their industrial differences became apparent), and adding a sixth division for the production of scattered areas of production—was as follows: Appalachian, 235,999,859; Lima-Indiana-Illinois, 219,609,347; Mid-Continent, 136,148,892; Gulf, 159,520,306; California, 27,931,687; and others, 3,367,666; the leading producers in 1907-1908 being the Mid-Continent and the California areas.

The world's output of oil was trebled between 1885 and 1895, and quadrupled between 1885 and 1900. In this increase the United States had the largest share. So recently as 1902 the output of the United States was little greater than that of Russia (the two yielding 91.4% of the world's product), but this advantage has since then been greatly increased, so that the one has produced 63.1 and the other 21.8% of the total output of the world. In 1908 the Geological Survey issued a preliminary map of the then known areas productive of oil and natural gas in the United States, estimating the extent of the former at 8850 and of the latter at 9365 sq. m. The supply of oil in this area was estimated at from 15,000,000,000 to 20,000,000,000 barrels; and the National Conservation Commission of 1908 expressed the opinion that in view of the rapid increase of production and the enormous loss through misuse the supply cannot be expected to last beyond the middle of this century.

Natural gas, as a source of light and for metallurgical purposes, became important in the mid-eighties. In recent years its use for Natural Gas. industrial purposes has lessened, and for domestic purposes increased. The existence of outflows or springs of gas in the region west of the Alleghanies had long been known, and much gas was used for illuminating purposes in Fredonia, New York, as early as 1821. Such gas is a more or less general concomitant of oil all through the petroleum-bearing areas of the country. The total output of the country rose from a value of $215,000 in 1882 to one of $54,640,374 in 1908, with several fluctuations up and down in that interval. Pennsylvania, with a product valued at $155,620,395 from 1899 to 1908, West Virginia with $84,955,496, Ohio with $48,172,450 and Indiana with $46,141,553 were the greatest producers of the Union.

The National Conservation Commission in 1908 estimated the area of the known gas fields of the country at 9000 sq. m.; the portion of their yield in 1907 that was utilized at 400,000,000,000 cub. ft.; and the waste at an equal amount—more than 1,000,000,000 of cub. ft. daily, or enough to supply all the cities in the United States of above 100,000 population.

Of other non-metallic mineral substances, apart from coal, petroleum and natural gas, little need be said in detail. Stone is of the greatest actual importance, the value of the quarry output, including some prepared or manufactured product, such as dressed and crushed stone, averaging $65,152,312 annually in 1904-1908. Limestone is by far the largest element, and with granite makes up two-thirds of the total value. Vermont, Pennsylvania and New York are the leading producers. In this, as in other cases, actual product may indicate little regarding potential resources, and still less regarding the distribution of these throughout the Union. Glass and other sands and gravel ($13,270,032), lime ($11,091,l86), phosphate rock ($10,653,558), salt ($7,553,632), natural mineral waters ($7,287,269), sulphur ($6,668,215, almost wholly from Louisiana), slate ($6,316,817), gypsum ($4,138,560), clay ($2,599,986), asphalt ($1,888,881), tale and soapstone ($1,401,222), borax ($975,000, all from California), and pyrite ($857,113) were the next most important products in 1908. It may be noted that the output in almost every item of mineral production was considerably greater in 1907 than in 1908, and the isolated figures of the latter year are of little interest apart from showing in a general way the relative commercial importance of the products named. In the yield of gypsum, phosphate rock and salt the United States leads the world. In sulphur it is a close second to Sicily. Phosphate rock is heavily exported, and in the opinion of the National Conservation Commission of 1908 the supply cannot long satisfy the increasing demand for export, which constitutes a waste of a precious natural resource. Other minerals whose production may be found stated in detail in the annual volume on Mineral Resources of the United States Geological Survey are: natural pigments, felspar, white mica, graphite, fluorspar, arsenic, quartz, barytes, bromine. Some dozens of varieties of precious stones occur widely. Of building-stone, clay, cement, lime, sand and salt, the country's supply was estimated by the National Conservation Commission of 1908 to be “ample.”

In 1907 iron ore was mined for blast-furnace use in twenty-nine states only, but the ore occurs in almost every state of the Union. Iron. As nearly as can be estimated from imperfect statistics, the total ore production of the country rose steadily from 2,873,400 long tons in 1860 to 51,720,619 tons in 1907. The United States became practically independent of foreign ore imports during the decade 1870 to 1879. The iron-producing area of the country may be divided, with regard to natural geographic, historic and trade considerations, into four districts: (1) the Lake Superior district, embracing the states of Minnesota, Michigan and Wisconsin; (2) the southern district, embracing the triangle tipped by Texas, Maryland and Georgia; (3) the northern district, embracing the triangle tipped by Ohio, New Jersey and Massachusetts, plus the states of Iowa and Missouri; (4) the western district, which includes the states of the Rocky Mountain region and Pacific coast. Of these districts the Lake Superior region—which embraces the Marquette range (opened in 1854), the Menominee (1872), the Gogebic (1884), the Vermilion (1884) and the Mesabi (1892)—first attracted exploration about 1844, when the copper deposits of the same region were opened, and produced from 1854 to 1908 a total of 410,239,551 long tons, of which 341,036,883 were mined in the period 1889-1908. From the Mesabi range alone, opened in 1892, no less than 168,143,661 long tons were taken up to 1908. The
