in the art of war, are such as are commanded in from the country, to march with an army for mending the ways, for working on intrenchments and fortifications, and for making mines and approaches. The soldiers are likewise employed for all these purposes. Most of the foreign regiments of artillery have half a company of pioneers, well instructed in that important branch of duty. Our regiments of infantry and cavalry have three or four pioneers each, provided with aprons, hatchets, saws, spades, and pickaxes. Each pioneer must have an axe, a saw, and an apron; a cap with a leather crown, and a black bearskin front, on which is to be the king's crest in white, on a red ground; and the number of the regiment is to be on the back part of it.
