repaired, and it went on doing duty until one of its trunnions was knocked off, and even then, like the gallant Widderington, at Chevy Chase, it fought upon its stumps; for, on being sunk into the ground, and fired at a high elevation, it was kept at work up to the end of the siege. Some of these guns are pitted with cannon-shot even as far back as the breech, and one or two are hit in their very stern-most parts. These wounds are the result of ricochet firing, a kind of practice which enables a shot to drop in the most unexpected places. In the mounting yard, as it is termed, which lies between the gun and carriage factories, the field-pieces are mounted upon their carriages and fitted up for service previous to their removal to the depôt of artillery near the Common. Since the war the captured cannon from Sebastopol have been stored here preparatory to their being either broken up or distributed as trophies to the various towns of the United Kingdom. Of these guns 1079 are of iron and 94 of brass. They are of admirable metal, and would have proved very serviceable, except that unfortunately their bore does not suit any of our shot. Gun-carriages rent by the bursting of guns, or so unscientifically constructed as inevitably to destroy themselves, like the iron carriages taken from the enemy at Kertch, are kept as lessons for the Captain Instructor to dwell upon, when he takes round his bevy of young artillery cadets. This official performs the essential duty of giving the future artillery officer a clear insight into the method of constructing and repairing all the more essential engines and tools he will have to work with--such as guns, gun-carriages, &c., and of obtaining a general notion of the relative strength of metals, and of the value of the various materials out of which the munitions of war are formed. The vast workshops of Woolwich afford an admirable field for the acquisition of this kind of knowledge.
