BASKETS of Earth, in the military art, called by the French corbeillers, are small baskets used in sieges, on the parapet of a trench, being filled with earth. They are about a foot and a half high, about a foot and a half in diameter at the top, and 8 or ten inches at bottom; so that, being set together, there is a sort of embrasures left at their bottoms, through which the soldiers fire, without exposing themselves.
