Ah, parlour cannon. Who among us has not built one in the idle hours between chase and whist? I myself have fashioned one out of the mouthpiece of an Oriental “Hou-kah” and the base of a common telegraph console. It absolutely devastated the jellied quail I had brought for supper. But this is the tiniest parlour cannon of them all — yet still packs a ruddy knuckle, what? That ale receptacle was quite disintegrated. Yes; capital.
