One of the simplest of the foot latches consists of a piece of wood cut
out by the aid of axe and hunting-knife to the form shown by Fig. 199; a
hole in the door cut for that purpose admits the flattened and notched
end and upon the inside it fits the round log sill. The owner of the
shack, when reaching home, steps upon the foot latch (Fig. 199), which
lifts up the catch (on the inside) and allows the door to swing open.
