To shingle with bark, cut the bark in convenient sections, commence at the
bottom, place one piece of bark set on edge flat against the wall of your
shelter, place a piece of bark next to it in the same manner, allowing the
one edge to overlap the first piece a few inches, and so on all the way
around your shack; then place a layer of bark above this in the same
manner as the first one, the end edges overlapping, the bottom edges also
overlapping the first row three or four inches or even more. Hold these
pieces of bark in place by stakes driven in the ground against them or
poles laid over them, according to the shape or form of your shelter.
Continue thus to the comb of the roof, then over the part where the bark
of the sides meets on the top lay another layer of bark covering the
crown, ridge, comb, or apex and protecting it from the rain. In the
wigwam-shaped shelters, or rather I should say those of teepee form, the
point of the cone or pyramid is left open to serve as chimney for smoke to
escape.
