In Fig. 236 we see that the side walls of the pen are allowed to extend on
each side so as to enclose a roofed-over open-air room, or, if you choose
to so call it, a front porch, veranda, stoop, piazza, or gallery,
according to the section of the country in which you live.
So as to better understand this cabin the plan is drawn in perspective,
with the cabin above and made to appear as if some one had lifted the
cabin to show the ground-floor plan underneath. The olebo roof is built
upon the same plan as the Kanuck (Fig. 244), with this exception, that in
Fig. 244 the rooftree or ridge-log is supported by cross logs which are a
continuation of the side of the house (_A_, _A_, Figs. 242, 244, and 245),
but in the olebo the ridge pole or log is supported by uprights (Figs.
236 and 237). To build the olebo lay the two side sill logs first (_A_,
_B_, and _C_, _D_, Fig. 236), then the two end logs _E_, _F_, and _D_, _B_
and proceed to build the cabin as already described, allowing the
irregular ends of the logs to extend beyond the cabin until the pen is
completed and all is ready for the roof, after which the protruding ends
of the logs _excepting the two top ones_ may be sawed off to suit the
taste and convenience of the builder. The olebo may be made of any size
that the logs will permit and one's taste dictate. After the walls are
built, erect the log columns at _A_ and _C_ (Fig. 236), cut their tops
wedge shape to fit in notches in the ends of the projecting side-plates
(Fig. 144, _A_ and _B_); next lay the end plate (_G_, Fig. 236) over the
two top logs on the sides of your house which correspond to the
side-plates of an ordinary house. The end plate _G_ is notched to fit on
top of the side-plates, and the tops of the side-plates have been scored
and hewn and flattened, thus making a General Putnam joint like the one
shown above (_G_, Fig. 236); but when the ends of the side logs of the
cabin were trimmed off the side-plates or top side logs were allowed to
protrude a foot or more beyond the others; this was to give room for the
supporting upright log columns at _A_ and _C_ (see view of cabin, Fig. 236
and the front view, Fig. 237). _H_ and _J_ (Fig. 237) are two more upright
columns supporting the end plate which, in turn, supports the short
uprights upon which the two purlins _L_ and _M_ rest; the other purlins
_K_ and _N_ rest directly upon the end plate (Fig. 237). The rear end of
the cabin can have the gable logged up as the front of the house is in
Fig. 240, or filled in with uprights as in Fig. 247. The roof of the olebo
is composed of logs, but if one is building an olebo where it will not be
subjected during the winter to a great weight of snow, one may make the
roof of any material handy.
