Excerpt from book: material for rubble work; the gray wacke slate is in very common use as a nagging and coping stone. They are found, abundantly, in many parts of our country. Several quarries are worked in Connecticut, Massachusetts, and New-York, from which an excellent flagging and coping stone is obtained. Common Roof Slate requires no particular description. There are many varieties of this stone which are very suitable for rubble work. The best for roof covering, is that which splits into thin even layers, is free from the ores of iron, particularly the sulphurets, which are most deleterious to it, and absorbs but little moisture. Good roof slate is quarried extensively in many parts of the United States, chiefly in Maine, at Hoosack, in New-York, and nearer the Susquehanna river, in the counties of York and Lancaster. Pennsylvania. CALCAREOUS STONES. This very abundant class, composed of innumerable varieties, is the most useful building material known to the engineer and architect, both for common and ornamental purposes; arising from the strength, hardness, durability, and beauty both of color and polish, which it is known to possess. It also furnishes the principal ingredient in the composition of every variety of cement used for uniting stones artificially. Calcareous stones, distinguished by the more common appellation of Lime Stone and Marble, are composed principally of Carbonate of Lime combined with the metallic oxides, and several other foreign minerals. They seldom occur in a pure state; when found so, the color of the stone is a pure white, and it is shown, by analysis, to be composed of lime, carbonic acid, and a small quantity of water. The general properties of this class of stone, both physical and chemical, are so well known, as hardly to require any desc...
