Scarce guide on the manufacturing of gunpowder, a subject of considerable concern to the colonies, who faced shortages of ammunition. Issued by the Second Continental Congress, the present pamphlet specifically calls on the tobacco colonies to capitalize on the nitrate-impregnated soil around their warehouses by erecting saltpeter factories nearby. John Hancock's speech to Congress of July 28, 1775, is included: "the United Colonies may not, during the continuance of their present important contest for Liberty, ... be under the expensive, uncertain and dangerous necessity of relying on foreign importations for Gun-powder."
