Fig. 118.—Construction of Door Wires for Aviary.
The wiring is all straightforward work. The wires are passed through the top rails to those below and clipped off level at the top. Six feeding-holes are required, one in the centre at each end, and two at the back and front close to the perches. The top ends of these wires are pushed up through the rails; the circular ends are slightly sunk and fixed with small staples. Six wires are omitted from the middle of the front to allow for the door. The cross-wires, which should be of a stronger gauge, are then put in. In the back and ends it is immaterial whether they are put inside or out, but at the front they must be inside. The six wires above the door are inserted in twos, being returned in the same manner as the lower ends of the door wires (see [Fig. 118]), and soldered to the cross-wire, which is afterwards bound to the others with thin pliable coil wire. In making the sliding door, the returned ends of the wires are soldered to the base wire inside, so that the ends may fit round the wires of the doorway; the top ends fit round those above the cross-wire, and when the door is in place a scroll-piece is soldered on outside (see [Fig. 111]).

Eight corner-pieces of the split stuff are put on close against the wires, being secured to the uprights and rails with pins. Two pieces of ¼ in. board are next got out for the top, measuring 2 ft. 10 in. long, 4 in. across the centre, and slanting at the upper edge to ¼ in. at the ends. The design is worked on these in split, the boards being kept in place with pins driven through the top rails, and the back and front connected at the top point by a length of wood of 2-in. by 1-in. section (see [Fig. 119]). The roof-pieces, 1 ft. 5½ in. by 1 ft. 7¼ in. by ¼ in., are nailed on and covered with split stuff, as shown by [Fig. 120].
