Across the top of the trapping pit was a thick stick or pole, and on this was fastened a plank, which covered the top of the trap. On one end of this plank was a piece of venison, and on the other a stone. The way the trap was meant to work was this: The wolf would come to the venison, and just as it got on the plank to eat it, the plank would turn, causing the wolf to fall into the pit. The weight of the stone at the other end would bring the plank up again, ready baited for another wolf.
