amount being valued at $12,235,674 and being 12.09% of the value of the product of the entire country. In 1906 there was an output of only 7,673,477 barrels, valued at $6,770,066, being 7.3% of the product value of the entire country. The Indiana coal fields, which cover an area of between 7000 and 7500 sq. m. in the west and south-west, chiefly in Clay, Vigo, Sullivan, Vermilion and Greene counties, yielded in 1902 9,446,424 tons, valued at $10,399,660; in 1907, 13,985,713 tons, valued at $15,114,300; the production more than trebled since 1896, when it was 3,905,779 tons. The deposits consist of workable veins, 50 to 220 ft. in depth, and averaging 80 ft. below the surface. It is a high grade block, or "splint" coal, remarkably free from sulphur and rich in carbon, peculiarly adapted to blast furnace use. The quarries and clay beds of the state are of great value. The quarries of sandstone and limestone are chiefly in the south and south-central portions of the state. The value of the limestone quarried in 1908 was $3,643,261, as compared with $2,553,502 in 1902. The Bedford oolitic limestone quarries in Owen, Monroe, Lawrence, Washington and Crawford counties furnish one of the most valuable and widely used building stones in the United States, the value of the product in 1905 being $2,492,960, of which $2,393,475 was from Lawrence and Monroe counties and $1,550,076 from Lawrence county alone. Beds of brick-clays and potters' clay are widely distributed throughout the state, the total value of pottery products in 1902 being $5,283,733 and in 1906 $7,158,234. Marls adapted to the manufacture of Portland cement are found along the Ohio river, and in the lake region in the north. In 1905 and 1906 Indiana ranked third among the states in the production of Portland cement, which in 1908 was 6,478,165 barrels, valued at $5,386,563--an enormous advance over 1903, when the product was 1,077,137 barrels, valued at $1,347,797. The production of natural rock cement, chiefly in Clark county, is one of the two oldest industries in the state, but in Indiana as elsewhere it is falling off--from an output in 1903 of about 1,350,000 barrels to 212,901 barrels (valued at $240,000) in 1908. There are many mineral springs in the state, and there are famous resorts at French Lick and West Baden in Orange county. A large part of the water bottled is medicinal: hence the high average price per gallon ($0.99 in 1907 when 514,366 gallons were sold, valued at $507,746, only 2% being table waters). In 1907 19 springs were reported at which mineral waters were bottled and sold; they were in Allen, Hendricks, Pike, Bartholomew, Warren, Clark, Martin, Brown, Gibson, Wayne, Orange, Vigo and Dearborn counties. A law of 1909 prohibited the pumping of certain mineral waters if such pumping diminished the flow or injured the quality of the water of any spring.
