or the long sides, and seven feet apart. Then
across them, at the end, lay two short ones, eleven feet apart. This
leaves about a foot projecting from each log. Roll the last two into
their resting places, and flatten them till they sit firmly. It is of
prime importance that each log rest immovably on the one below. Now
cut the upper part of each end log, to an edge over each corner. (Fig.
1.)

Next put on two long logs, roll them onto the middle, taking care to
change off, so the big end at a given comer may be followed next time
by the small end and insure the corner rising evenly. Roll one of
these large logs close to where it is to be placed, then cut on its
upper surface at each end a notch corresponding with the ridge on the
log it is to ride on. When ready, half a roll drops it into place. The
log should be one to three inches above the one under it, and should
not touch except at {61} the ends. Repeat the process now with the other
sides, then the two ends, etc., always keeping the line of the corner
plumb. As the walls rise, it will be found necessary to skid the
larger logs; that is, roll them up on two long logs, or skids, leaning
against the wall. (Fig. 2.)

When the logs are in place to the height of four and a half feet from
the ground, it is time to decide where the door and window are to be;
and at that place, while the next long log is lying on top, bottom up,
cut out a piece four feet long and four inches deep. Roll this log
into place. (Fig. 3.) One more log above this, or certainly two, will
make your shanty high enough for boys. Put on final end logs, then two
others across the shanty. (Fig. 4.) Roll up the biggest, strongest log
of all for the ridge (sometimes two are used side by side); it should
lie along the middle of the four cross pieces shown in Fig. 4.

The two cross logs, B and C, and the ridge log should be very strong,
as the roof is heavy. Now we are ready to cut the doorway and window.

First, drive in blocks of wood between each of the logs, all the way
down from A to the ground, and from B down to D, and C to E. (Fig. 5.)
Saw down now from A half-way through the ground log F. Then from B
down to half-way through the log D; now continue from G, cutting down
to half through the ground log. Use the ax to split out the upper half
of the ground log, between the saw-cuts and also the upper half of the
log D.
