24 June.--Last night the Count left me early, and locked himself into his own room. As soon as I dared I ran up the winding stair, and looked out of the window, which opened South. I thought I would watch for the Count, for there is something going on. The Szgany are quartered somewhere in the castle and are doing work of some kind. I know it, for now and then, I hear a far-away muffled sound as of mattock and spade, and, whatever it is, it must be the end of some ruthless villainy.
From Jonathan Harker's Journal, Dracula, by Bram Stoker
A mattock is a hand tool similar to a pickaxe. It is distinguished by the head, which makes it particularly suitable for digging or breaking up moderately hard ground. A mattock has a broad chisel-like blade perpendicular to the handle.This broad-bladed end is effectively an adze that could be used as a hoe as well. The reverse may have a pointed end, in which case the tool is called a pick mattock, or instead have an axe-like splitting end, then it is a cutter mattock. A combination axe and mattock used for fighting forest fires is a pulaski. In some regions of the southern USA, the mattock is called a "grub hoe" or "grub axe".
