round the small end of the cage until it finally meets
at the door hinge on the opposite side. The two halves of the cage
should now be separated by a grating of wire, as seen in the main
[Page 79]
illustration. This may be accomplished either by passing the wire
from side to side, around the base of each upright wire, or an
additional horizontal row of holes below the others may be punched
for the purpose. The door through which the call-bird is introduced
should next be made in the bottom section. There are two ways of
doing this: one method consists in sawing a hole three inches square
in the bottom board of the cage; and a cover consisting of a piece
of tin is made to slide beneath the heads of four tacks, two of which
are placed on each side of the opening. This form of door is perhaps
the simplest of the two. The other is shown separate at (_f_),
together with its mode of attachment.

It consists of two side pieces of wood, about a third of an inch
square, and three inches in length, and two shorter ones, two inches
in length. These are arranged into a square framework by a board
in each corner. Four holes are to be pierced in each side piece,
at equal distances. Commencing at the top, the door should then
be wired as directed for the cage. The lowest hole on each side
should be left open for a separate piece of wire. The cage should
now receive attention. The broad side is generally selected for
the door. Find the seven centre wires and connect them across the
middle by another horizontal bit of wire. This may be easily done
with a pair of pincers, by compressing a loop at each end of the
wire around the two which run perpendicularly at its ends. When this
is performed the five intermediate wires should be cut off about
a quarter of an inch below the horizontal wire, and the projecting
tips looped back over the cross piece, and made fast by the pincers.
The lower parts of the upright wires may now be cut off close to the
board. We will now take up the door. Pass a piece of wire through
the holes at the bottom, clap the door over the opening, and loop
the ends of the projecting wire loosely around the upright wires
at each side. This will allow the door to slide easily up and down.
Another wire should now be interlaced downwards through the centre
of the door, and bent into a ring at the top. Let the door rest
on the bottom of the cage, and, while in this position, adjust
the ring at the top around the central w
