hen it tries to back out.
Almost anyone can make this trap in a short time, and it will
catch the mice as surely as a more elaborate trap.

** Clear Wax Impressions from Seals [450]

A die must be slightly damp to make clear impressions on sealing
wax and to keep it from sticking to the wax. A very handy way to
moisten the die is to use a pad made by tacking two pieces of
blotting paper and one of

cloth to a wooden block of suitable size, and saturate the
blotters with water before using. Stamp the die on the pad and
then on the hot wax. The result will be a clear, readable
impression.

** A Window Stick [450]

Although the windows in factories and houses are usually provided
with weights, yet the stick shown in the sketch will be found very
handy in case all of the windows are not so equipped. It is made
of a piece of pine wood long

enough to hold the lower sash at a height even with the bottom of
the upper, and about 1-1/2 or 2 in. wide. Notches may be cut in
the stick as shown, each being wide enough to firmly hold the
sash. Thus, with the stick illustrated, the sash may be held at
three different heights on the side A, and at still another on the
side B.

** How to Make a Canoe [451]

A practical and serviceable canoe, one that is inexpensive, can be
built by any boy, who can wield hammer and saw, by closely
following the instructions and drawings, given in this article.

It is well to study these carefully before beginning the actual
work. Thus an understanding will be gained of how the parts fit
together, and of the way to proceed with the work.

Dimensioned drawings of the canoe and molds are contained in Fig.
1. The boat is built on a temporary base, A, Fig. 2, which is a
board, 14 ft. 1 in. long, 3 in. wide and 1-1/2 in. thick. This
base is fastened to the trestles and divided into four sections,
the sections on each side of the center being 4 ft. long.

The next thing to be considered are the molds (Fig. 3). These are
made of 1-in. material. Scrap pieces may be found that can be used
for these molds. The dimensions given in Fig 1 are for one-half of
each form as shown in Fig. 3, under their respective letters. The
molds are then temporarily attached to the base on the divi
