ssible with the round side of the tool.
Work down the outside line of the design, thus raising it.

Fold the leather on the line EF. Cut another piece of leather the
size of the side ECBD of the purse, and after putting the wrong
sides of the leather together, stitch around the edge as
designated by the letters above mentioned. Do not make this piece
come quite up to the line EF, so that the coins may be more easily
put in and taken out. About 1 in. from the lines EF on the piece,
stitch in a strip of leather about 1/4 in. wide when stitching up
the purse, through which to slip the fly AGH.

** Window Anti-Frost Solution [354]

A window glass may be kept from frosting by rubbing over the inner
surface a solution of 55 parts of glycerine and 1,000 parts of 60
per cent alcohol. The odor may be improved by adding a little oil
of amber. This solution will also prevent a glass from sweating in
warm weather.

** How to Make a Turbine Engine [355]

In the following article is described a machine which anyone can
make, and which will be very interesting, as well as useful. It
can be made without the use of a lathe, or other tools usually out
of reach of the amateur mechanic. It is neat and efficient, and a
model for speed and power. Babbitt metal is the material used in
its construction, being cast in wooden molds. The casing for the
wheel is cast in halves--a fact which must be kept in mind.

First, procure a planed pine board 1 by 12 in. by 12 ft. long. Cut
off six

[Illustration: Fig. 2]

pieces 12 in. square, and, with a compass saw, cut out one piece
as shown in Fig. 1, following the dotted lines, leaving the lug a,
and the projections B and b to be cut out with a pocket knife.
Make the lug 1/4 in. deep, and the projections B, b, 1/2 in. deep.
The entire cut should be slightly beveled.

Now take another piece of wood, and cut out a wheel, as shown in
Fig. 2. This also should be slightly beveled. When it is finished,
place it on one of the square pieces of wood, with the largest
side down, then place the square piece out of which Fig. 1 was
cut, around the wheel, with the open side down. (We shall call
that side of a mold out of which a casting is drawn, the "open"
side.) Place it so that it is even at the edge with the under
square piece and place the wheel so that the space between the
wheel and

[Illustration: Fig. 1]

the other piece of wood is an even 1/8 in. all the way around.
Then nail the w
