Black Lead.
Plumbago (black lead) is found in Amelia, Patrick, Amherst, Campbell,
Loudoun, Louisa, Albemarle and other counties. Some deposits are
very pure and large in quantity. It appears irregularly in different parts
of the state. In some localities it has been tested by analysis, in others
manufactured into pencils, and in others as a lubricant.
