To build a Pontiac, first erect the uprights _E_ and _E_, Fig. 37, then
the other two similar uprights at the rear and lay the side-plates _G_ in
the forks of the uprights; next erect the upright _H_ and one in the rear
to correspond, and across this lay the ridge-pole. Next take a couple of
logs and put them at the foot of the _E_ poles, or, if you want more room,
further back toward where the roof poles _F_ will come. Place one of these
logs on top of the other as shown in Figs. 36 and 39. Keep them in place
by driving sticks on each side of them. Put two more logs upon the other
side of the Pontiac and then lay your roof poles or rafters up against the
side-plates and over the logs as shown in diagrams 36, 37, and 39. Fig. 36
shows the roof partially shingled and the sides partially covered, so that
you may better understand how it is done.
