Marbles, like limestones, with which they are closely related, are very abundant in this country, and are also to be found in a great variety of colors. As early as 1804 American marble was used for statuary purposes. Early in the century it also obtained extensive employment for gravestones. Its use for building purposes has been more recent than granite and sandstone in this country; and it is coming to supersede the latter to a great degree. For mantels, fire-places, porch pillars, and like ornamental purposes, however, our variegated, rich colored and veined or brecciated marbles were in use some time before exterior walls were made from them. Among the earliest marble buildings were Girard College in Philadelphia and the old City Hall in New York, and the Custom House in the latter city, afterward used for a sub-treasury. The new Capitol building at Washington is among the more recent structures composed of this material. Our exports of marble to Cuba and elsewhere amount to over $300,000 annually, although we import nearly the same amount from Italy. And yet an article can be found in the United States fully as fine as the famous Carrara marble. We refer to that which comes from Rutland, Vt. This state yields the largest variety and choicest specimens. The marble belt runs both ways from Rutland County, where the only quality fit for statuary is obtained. Toward the north it deteriorates by growing less sound, though finer in grain; while to the south it becomes coarser. A beautiful black marble is obtained at Shoreham, Vt. There are also handsome brecciated marbles in the same state; and in the extreme northern part, near Lake Champlain, they become more variegated and rich in hue. Such other marble as is found in New England is of an inferior quality. The pillars of Girard College came from Berkshire, Mass., which ranks next after Vermont in reputation. The marble belt extends from New England through New York, Pennsylvania, Maryland, the District of Columbia, and Virginia, Tennessee, and the Carolinas, to Georgia and Alabama. Some of the variegated and high colored varieties obtained near Knoxville, Tenn., nearly equal that of Vermont. The Rocky Mountains contain a vast abundance and variety.
