When he sat at his shoemaking, he'd count his stitches by fives, and then put a price on his stitches, say half a farthing, and then see how much money he could get in an hour; and then ask himself how much money he'd get in a day at that rate; and then how much ten workmen would get working three, or twenty, or a hundred years at that rate--and all the while his needle would be going just as fast as if he left his head empty for the devil to dance in.
