pores of calcareous earths and stones; as we see calcareous drop stones generating every day by the percolation of water through lime stone, and new marble forming in the quarries from which the old has been taken out; and it might be asked whether it is more difficult for Nature to shoot the calcareous juice into the form of a shell, than other juices into the forms of chrystals, plants, animals, according to the construction of the vessels through which they pass? There is a wonder somewhere. Is it greatest on this branch of the dilemma; on that which supposes the existence of a power, of which we have no evidence in any other case; or on the first, which requires us to believe the creation of a body of water, and its subsequent annihilation? The establishment of the instance cited by M. de Voltaire, of the growth of shells unattached to animal bodies, would have been that of his theory. But he has not established it. He has not even left it on ground so respectable as to have rendered it an object of enquiry to the literati of his own country. Abandoning this fact, therefore, the three hypotheses are equally unsatisfactory; and we must be contented to acknowledge that this great phenomenon is as yet unsolved. Ignorance is preferable to error; and he is less remote from the truth who believes nothing, than he who believes what is wrong.
There is great abundance (more especially when you approach the mountains) of stone, white, blue, brown, &c., fit for the chisel, good mill stone, such also as stands the fire, and slate stone. We are told of flint, fit for gun flints, on the Meherrin in Brunswic, on the Missisipi between the mouth of Ohio and Kaskaskia, and on others of the Western waters. Isinglass or mica is in several places; load stone also, and an asbestos, of a ligneous texture, is sometimes to be met with.
Marl abounds generally. A clay, of which, like the sturbridge in England, bricks are made, which will resist long the violent action of fire, has been found on Tuckahoe Creek of James River, and no doubt will be found in other places. Chalk is said to be in Botetourt and Bedford. In the latter county is some earth, believed to be gypseous. Ochres are found in various parts.
