project a few inches. _B_ should be far enough below
_A_ to give the proper height for a railing around the platform. The
platform itself rests upon _B_. _A_ forms the top railing to the fence
around it.

Now take two of your sixteen-and-one-half-foot poles and place them
diagonally from corner to corner of the parallelogram with the small ends
of the poles lying over the ends of _A_ and the butt ends of the poles
extending beyond _C_, as in Fig. 82. Lash these poles securely in place.

Where the poles cross each other in the _X_, or centre, it is best to
flatten them some by scoring and hewing with a hatchet, but care must be
taken not to weaken them by scoring too deep. Next take your lash rope,
double it, run the loop down under the cross sticks, bring it up on the
other side, as in Fig. 83, then pull the two loose ends through the loop.
When they are drawn taut (Fig. 84), bend them round in opposite
directions--that is, bend the right-hand end of the rope to the right,
down and under the cross sticks, pull it out to the left, as in Fig. 84,
then bend the left-hand piece of rope to the left, down and under, pulling
it out to the right, as in Fig. 84. Next bring those two pieces up over
and tie them together in a square knot, as shown in Figs. 85 and 86.

Make a duplicate "kite" frame for the other side exactly as you made the
first one, and then arrange these two pieces on the ground with the cross
sticks _F_ and _F_ on the under-side and with their butt ends opposite the
butts of the similar poles on the other frame and about five feet apart.
Fasten a long line to the point where the two _F_ pieces cross each other
and detail a couple of scouts to hold each of the butt ends from slipping
by placing one of their feet against the butt, as in Fig. 82, while two
gangs of men or boys pull on the ropes and raise the kite frames to the
positions shown in Figs. 81 and 88.

Be careful, when raising the frames, not to pull them too far so that they
may fall on some unwary workman. When the frames are once erected it is an
easy matter to hold them in place by guy-ropes fastened to stones, stakes,
or trees or held by men or boys, while some of the shorter braces are
fastened to hold the two kite frames together, as in Fig. 90, wherein you
may see these short br
