Charles Sylvester, Supplement to the Fourth, Fifth… (1824)
“ The smith’s anvil is generally placed loose upon a wooden block, the root-end of an oak tree being preferred. The anvils used in cutlery, and for files, are fastened into a large block of stone, which is doubtless better than having the anvil loose upon a small block. The more firmly the anvil is connected with the earth, and the substance it stands upon, the greater will be the effect of the blow of the hammer. ”
