The caisson ([Fig. 85]) consists of the limber, which is identical with the gun-limber, and the caisson-body, carrying two ammunition-chests similar to those of the limber. It is of steel and iron, with brakes like those on the carriage. There are two foot-boards, and it has arrangements for carrying the spare wheel, intrenching-tools, spare pole, single-trees, and other accessories.
