Garnett in his 1800 tour of Scotland describes the use of a hand quern as follows: "The quern consists of two circular pieces of stone, generally grit or granite, about twenty inches in diameter. In the lower stone is a wooden peg, rounded at the top; on this the upper stone is nicely balanced, so as just to touch the lower one, by means of a piece of wood fixed in a large hole in this upper piece, but which does not fill the hole, room for feeding the mill being left on each side: it is so nicely balanced, that though there is some friction from the contact of the two stones, yet a very small momentum will make it revolve several times, when it has no corn in it. The corn being dried, two women sit down on the ground, having the quern between them; the one feeds it, while the other turns it round, relieving each other occasionally, and singing some Celtic songs all the time."
