Framing.
Cut the sticks A, C and B, D exactly equal in length and nail them to the uprights A, B and C, D, as in Fig. 77, using one nail at each corner; this will adjust the frame and make the four corners square, after which you may secure them in position by diagonal pieces similar to those shown on the end, A, E, B, F, Fig. 77. The corners may then be nailed. In nailing a temporary piece it is only necessary to drive the nails far enough to hold for the time.
Next make the frame E, G, H, F, and in the middle of this frame nail on the two door-jambs I, J, and K, L. While some of the boys hold the front and rear frames in an upright position and the proper distance apart, others can nail on diagonals at the two ends, and, after all is square and plumb, the two string-pieces, A, E and C, G, may be securely nailed in place, and the rafter M, O nailed to M, N and O, P. This finishes the framework proper, for the club-house.
