ese are brazed and
fitted to slide they are fixed to the tube D by smaller tubes, one on
each side, in this manner. At f the arm is brought across the tube and
permanently fixed in the smaller tube. At g the other arm is brought
across in the same manner, but allowed to revolve in the small tube
brazed to the side of D; the end of this am (on the right of Fig. 43)
coming through the tube is coiled round and brazed to a screw, H,
fixed in such a manner that, though screwing freely through a burr
fixed on D, it cannot come out.

There are then no loose pieces to this net, which, from the nature of
the slides, is remarkably strong, and is easily opened and shut. (Fig.
44 shows the net folded, and with the arms slid down one on the
other.) To finish, tie a piece of whipcord in the holes from b to b,
and sew the holland all around the net as before, leaving plenty of
room for the playing of the slides; the "leno" is then sewn to this in
the usual manner, and thus becomes a fixture, as in the preceding net.

To open and fix the net from the position shown in Fig. 44 (which for
the sake of clearness is shown without the "leno "), pull the whipcord
C (now hidden, of course, by the holland) and ease up the slides; bend
over the revolving arm until the screw H comes over the hole in the
burr on D. Push the walking stick A (Fig. 45) into the tube D, and
screw up H, the point of which enters the stick, and firmly fixes and
locks the net. Fig. 45 shows the net ready for use.

The arrangement of the whipcord at C is to enable the net to be used
as a "sugaring" net in addition to its ordinary use for catching; C
being pressed against a tree, the corner of a wall, a fence, or a gas
lamp, etc, readily accommodates itself to any angle required.

A useful net for sugaring purposes, if Fig. 45 is not used, is one
recommended by Dr. Guard Knaggs. It is of triangular shape, the frame
of it being formed by socketing two pieces of paragon wire into a
metal Y piece, and connecting their diverging extremities by means of
catgut, which, when pressed against a tree or other object, will adapt
itself to the outline of it, as shown below by the dotted line (Fig.
46).

Killing Insects.--Having caught your butterfly, you will wish to kill
it in the most painless and least troublesome manner. For this purpose
you will require a "cyanide bottle." Purchase, therefore, at the
druggist's a wide-mouthed bottle (a 4 oz. bottle is a handy size for
the p
