Instead we
followed the professor's directions and tied cleats to each stick, as
shown in Fig. 235, so as to form sockets. Then the sticks were laid across
each other, each stick fitting into the socket of the other, just like a
mortised joint. A coat of shellac on the bottom of each cleat glued it
temporarily to the stick, after which it was very tightly bound with fine
cord. The stick and cleats were now thoroughly shellaced. The end of each
stick was tapered off to receive a brass ferrule of the kind used on
chisel handles. They can be bought at any hardware store. At the end of
the backbone we fastened hooks made of brass, bent to the form shown in
Fig. 236. The cross sticks were also provided with hooks, but these were
double, as shown in Fig. 237, so that a hook lay on both the front and the
rear side of the frame.

The frame was covered with a kind of cloth called "percaline." The cloth
was hemmed along each edge over heavy picture wire, and at each corner the
wire was twisted around a small solid ring of brass.
