A short gun, capable of carrying a large ball, and useful in close engagements at sea. It takes its name from the large iron-foundry on the banks of the Carron, near Falkirk, in Scotland, where this sort of ordnance was first made, or the principle applied to an improved construction. Shorter and lighter than the common cannon, and having a chamber for the powder like a mortar, they are generally of large calibre, and carried on the upper works, as the poop and forecastle.
