IN building a shelter use every and any thing handy for the purpose;
ofttimes an uprooted tree will furnish a well-made adobe wall, where the
spreading roots have torn off the surface soil as the tree fell and what
was the under-side is now an exposed wall of clay, against which you may
rest the poles for the roof of a lean-to. Or the side of the cliff (Fig.
23) may offer you the same opportunity. Maybe two or three trees will be
found willing to act as uprights (Fig. 24). Where you use a wall of any
kind, rock, roots, or bank, it will, of course, be necessary to have your
doorway at one side of the shack as in Fig. 23. The upright poles may be
on stony ground where their butts cannot well be planted in the earth, and
there it will be necessary to brace them with slanting poles (Fig. 25).
Each camp will offer problems of its own, problems which add much to the
interest and pleasure of camp making.
