Commence at the bottom and lay the first row with the edges overlapping
for walls; for the roof you may lay one row of shingles from the bottom up
to the ridge and hold them in place by resting a pole on them; then lay
the next row of shingles alongside by slipping the edges under the first.
When you have the two sides covered, put bark over the ridge as shown in
Fig. 36. This will make a beautiful and comfortable little camp.
