An Accurate Account can be Kept of Parts or Score for Any Game by Pulling the Strips
From unruled paper cut a piece, as shown at A in the sketch, and make slits parallel and evenly spaced with a sharp knife. Also cut six strips, similar to the one shown at B, to fit the slits cut in A. The strips are numbered as shown and inserted on the under side of A, and by pulling the strips as shown, one can count up the number of parts or keep tally on any game. By making more slits and using more strips very large numbers can be recorded.
