- n. The hole in a shell prepared for the reception of the fuse.
Sorry, no etymologies found.
The amazing force of expansion is also shown from the distance to which these iron plugs are thrown out of the fuse-hole.
Iron shells of different sizes, from the thirteen-inch shell to the cohorn of four inches diameter, were nearly filled with water, and an iron plug was driven in at the fuse-hole by a sledge-hammer.
It was found, however, that the plug could never be driven so firmly into the fuse-hole as to resist the expanding ice, which pushed it out with great force and velocity, and a bolt or cylinder of ice immediately shot up from the hole; but when a plug was used that had springs which would expand and lay hold of the inside of the cavity, so that it could not possibly be pushed out, the force of expansion split the shell.
