BARRELS, in military affairs, are of various kinds.

Fire-Barrels are of different sorts: some are mounted on wheels, filled with composition and intermixed with loaded grenades, and the outside full of sharp spikes: some are placed under ground, which have the effect of small mines: others are used to roll down a breach, to prevent the enemy’s entrance.—Composition, corned powder 30lb. Swedish pitch 12, saltpetre 6, and tallow 3. Not used now.

Thundering-Barrels are for the same purpose, filled with various kinds of combustibles, intermixed with small shells, grenades, and other fire-works. Not used now.

Powder-Barrels are about 16 inches diameter, and 30 or 32 inches long, holding 100 pounds of powder.

The whole barrels are made to contain 100 pounds, and the half barrels 50 pounds of powder; but of late only 90 pounds have been put into the barrels, and 45 into the half barrels; which, by leaving the powder room to be shifted, preserves it the better.

Budge Barrels, hold from 40 to 60 pounds of powder; at one end is fixed a leather bag with brass nails: they are used in actual service on the batteries, to keep the powder from firing by accident, for loading the guns and mortars.

Budge-Barrels contain 38 lbs.
