Having your uprights in place, extending above ground five feet or more,
lay a top pole across, fitting its ends into the forked tops of the
uprights. Against this top pole rest five or six slender poles at
regular distances apart, one end of each against the top pole and the
other end on the ground slanting outward and backward sufficiently to
give a good slope and allow sleeping space beneath. At right angles to
the slanting poles, lay across them other poles, using the natural pegs
or stumps left on the slanting poles by lopped-off branches, as braces
to hold the cross poles in place (Fig. 18).

When building the frame be sure to place the slanting poles so that
the little stumps left on them will turn _up_ and not down, that they
may hold the cross poles. Try to have spaces between cross poles as
regular as possible. A log may be rolled up against the ground ends of
the slanting poles to prevent their slipping, though this is rarely
necessary, for they stand firm as a rule.

You can cover the frame with bark and then thatch it, which will render
the shelter better able to withstand a storm, or you may omit the bark,
using only the thatch as a covering. Put on very thick, this should make
the lean-to rain-proof.
