The American Journal of Science and Arts, Vol. 10 (Classic Reprint)

Excerpt from The American Journal of Science and Arts, Vol. 10

Limestone is common all over the county. It is found on the tops of many of the bills, but in far greater quantities in the earth at their bases; beds of it being brought to light by the washing away of the superincumbent earth in the courses of rivers and creeks. It is generally impregnated with iron, which gives it a brown, or ochreous cast, when burnt and slaked for use; this does nor prevent its making excellent mortar, when duly proportioned With sand; and to give it that clear white so much admired in the plaister for inside work, we make use of a coat prepared from lime made of burnt shells, than which nothing can give a purer white.
