and a section of wood or bristol board, cut to a 45 degree angle, placed inside it, to act as a support and brace to hold the wall true while the glue is hardening. All the elevations should be glued in place in turn, and when they are completed braces should be installed here and there as necessary. The interior should then be shellacked. In fitting roofs to small bristol models all bends made in the roof must first be cut slightly on the outside line and a V-shaped channel cut out on the underneath parts, so that the bending will not crack the bristol board. To fit a roof, one must cut it out by checking off the boundaries with pencil marks, and cutting away until the desired fit is secured. The chimney may be
planed from strips of white pine, and should be placed in position before the roof is shellacked, as glue does not adhere readily to shellac.
If water color or ink wash is contemplated for outside rendering of architectural details, the outside of the model should not be shellacked. When it is planned to paint with oil, on the contrary, the surface must have a coat of shellac.
Before starting the work serious consideration must be given to the scale. The necessity for trans
porting the model through doorways and elevators, so that it may be exhibited readily, must be borne in mind. When the scale has been decided upon a carpenter should be employed to make a wood frame, on the plan of a checkerboard, of 1 in. x 3 in. white pine, with inside braces countersunk, glued and screwed in place. One side of this frame should be covered with compo board, glued and nailed
