_Block_-CARRIAGE, a carriage which is made from a solid piece of timber, hollowed out so as to receive the gun or howitzer into the cap-squares. The lower part of the cap-square is let into the solid wood, and the gun or howitzer is either elevated or depressed by a screw, as in other carriages. The limber for this carriage carries two large chests for ammunition, and takes four men. The pintle of the limber is so constructed as to receive the gudgeon of the carriage; by which means a greater relief is afforded when the carriage passes over rough ground. _Block_-CARRIAGES are also used by the horse-artillery as curricles. They are particularly useful on mountain service. The original inventor of them, is the British Colonel Congreve, author of many other important military inventions. _Truck_-CARRIAGES are to carry timber and other heavy burthens from one place to another, at no great distance: they serve also to convey guns or mortars upon a battery, whither their own carriages cannot go, and are drawn by men as well as horses. _Ponton_-CARRIAGE. Carriages of this kind are solely for transporting the pontons; they had formerly but two wheels, but are generally now made with four. The making use of two-wheel carriages for travelling a great way, is contrary to sense and reason; because the whole weight lying upon the two wheels, must make them sink deeper into the ground, than those of a four-wheel carriage.
