Independent of those manufactories which are established in Lexinton, there are several common potteries, and one or two powder-mills, the produce of which is consumed in the country or exported to Upper Carolina and Low Louisiana. The sulphur is obtained from Philadelphia and the saltpetre is manufactured in the country; the materials are extracted from the grottos, or caverns, that are found on the declivity of lofty hills in the most mountainous part of the state. The soil there is extremely rich in nitrous particles, which is evidently due to {126} the chalky rock, at the expense of which all these excavations are formed, as well as for vegetable substances, which are casually thrust into their interior. This appears to demonstrate that the assimilation of animal matters is not absolutely necessary, even in the formation of artificial nitrous veins, to produce a higher degree of nitrification. Saltpetre of the first preparation is sold at about sixpence halfpenny per pound. Among the various samples I have seen, I never observed the least appearance of marine salt. The process that is used is as defective as their preparation of salt; I only speak relative to the extraction of the saltpetre, not having seen the powder-mills.

The majority of the inhabitants of Lexinton trade with Kentucky;[41] they receive their merchandize from Philadelphia and Baltimore in thirty-five or forty days, including the journey of two days and a half from Limestone, where they land all the goods destined for Kentucky.
