STONE. Stone suitable for building and other industrial purposes is abundant in almost every State. Because of its hulk and the consequent shipping expenses, its production is largely lim ited to a comparatively local market. Hence in many of the States which have the most valuable resources of stone the quarrying industry has scarcely more than begun. The utilization of stone varies with the economic condition of the country, the total value having fallen from $53, 035,620 in 1889 to $31,340,171 in 1896. and ad vanced steadily to $55,615,926 in 1901. Lime stone is in most common use, only a few States failing to report its production ill the latter year, when its aggregate value was $21,747,061. This figure does not include limestone to the value of $4,659,836 used for flux. About $8,204,054 worth of limestone was burned into lime, the bulk of the remainder being used for building purposes, o• crushed for road-making. Indiana leads in the
quarrying of limestone for building purposes. Granite is second in importance, the value of the product in 1900 being $14.266,104. While its production is also widely distributed, New Eng hunt yields the largest quantities. 'Maine leads in its production for building purposes, and er mont in its production for monumental purposes. The value of sandstone in 1901 was $8,844,974, including Bluestone, grindstones, and whet stones. Pennsylvania, Ohio, and New York are the largest producers of these varieties. New York and Vermont prodUce most of the slate and Vermont and Georgia the bulk of the marble, the value of these two products in 1901 being re spectively $4,787,525 and $4,965,699. The value of trap-rock was $1,710•857• about one-half of which was contributed by New Jersey.
