"Instructions for the Manufacture of Saltpetre." 14 pages. Columbia, S.C. Charles P. Pelham, State Printer. 1862. "Published by authority of the executive council under direction of Col. James Chestnut, Jr., chief of Military Department." " This pamphlet is issued with the view of supplying information to those who may be inclined to engage in the production of saltpetre. As the refinement will require a process much more difficult and expensive, the State will undertake that. Private enterprise can thus readily furnish the crude material, which the State will purchase at a fair price, and prepare for all the uses required."
