and place the zinc in the porous cell. Attach the other end
of the wire to the wax impression.

The wax impression is made by pouring melted beeswax on the
article you wish to reproduce and removing after the wax gets
cold. The wax mold then should be coated with black lead and
polished. This is done with a camel's hair brush. A fine copy can
be made on the wax impression after the battery has been running
about 12 hr.

** How to Make Skating Shoes [158]

Remove the clamp part, as shown in Fig. 1, from an ordinary clamp
skate. Drill holes in the top part of the skate

[Illustration: Skating Shoes]

for screws. Purchase a pair of high shoes with heavy soles and
fasten the skates to the soles with screws, as shown in Fig. 2.
When completed the skating shoes will have the appearance shown on
Fig. 3. These will make as good skating shoes as can be purchased,
and very much cheaper.

** How to Make a Self-Setting Rabbit Trap [158]

Secure a good-sized box, say, 1 ft. high, 1-1/2 ft. wide, and 3
ft. long; and to the bottom, about 10 in. from one end, fasten a
2-in. square piece, A, Fig. 1, extending the width of the box.
Place a 10-in. board sloping from the end of the box to the cleat
A. The swing door B, Fig. 1, is made as shown

[Illustration: Self-Setting Trap]

in Fig. 2, which represents the back side of the door. Sheet metal
or tin is cut to the proper size and tacked around the edge of the
hole. This prevents the animal from gnawing its way out, also
provides a way to make the hole of different sizes for squirrels
or other animals. The hole in the door should be about 2 in. wide
and 4 in. high for rabbits. The door is made to swing freely on
two large nails driven through the sides of the box. The hole in
the door being only large enough to admit a small portion of the
rabbit's head, the rabbit will push its way through to the bait,
causing the door to swing back and up, and it will close by its
own weight when the animal is inside. A small door is provided in
the other end to remove the animals caught.

The advantage of this trap is that where one animal is caught
others are liable to follow, and several rabbits will be trapped
at a time. Then, too, the rabbits are not harmed in any way as
they would be if caught in an ordinary trap.
