and the bottom, 1/4 in. from the center and opposite each other.
Then cut a curved line from one hole to the other, as shown at B.
A piece of lead, which can be procured from a plumber, is cut in
the shape shown in Fig. 2, the size being 1 by 1-1/8 by 1-1/4 in.
An ordinary rubber band is secured around the neck of the piece of

[Illustration: Rolling Can Toy]

lead, as shown in Fig. 3, allowing the two ends to be free. The
pieces of tin between the holes A, Fig. 1, on both top and bottom,
are turned up as in Fig. 4, and the ends of the bands looped over
them. The flaps are then turned down on the band and the can parts
put together as in Fig. 5. The can may be decorated with brilliant
colored stripes, made of paper strips pasted on the tin. When the
can is rolled away from you, it winds up the rubber band, thus
storing the propelling power which makes it return. --Contributed

** How to Make a Portfolio [225]

Secure a piece of Russian modeling calf leather of a size equal to
12 by 16 in. Make a paper pattern of the size indicated in the
accompanying drawing, putting in the design.

The necessary tools consist of a stick with a straight edge and a
tool with an end shaped like that of a nutpick. A nutpick with a
V-shaped point will do if the sharpness is smoothed off by means
of a piece of emery paper, so that it will indent without cutting
the leather. These tools can be bought for this special purpose,
but are not essential for this piece if the nutpick is at hand.
There

will also be needed a level, non-absorbent surface upon which to
lay the leather while working it. A piece of thick glass, metal,
or marble will serve.

Begin work by moistening the leather on the back side with a
sponge or cloth. Moisten as much as you dare and still not have
the moisture show on the face side. Next place the leather on the
glass, face up, and, holding the pattern firmly in place so that
it will not slip--if possible get some one to hold the pattern for
you--place the straight edge on the straight lines and mark out or
indent. After this has been done, mark over the design. A pencil
may be used the first time over.

The pattern is now to be removed and all the lines gone over with
the tool to make them deep and uniform.

The surplus stock around the edges may not be cut off. A neat way
to finish the edges is to punch a series of holes entirely
