Sandpaper all the surfaces and round the edges slightly. Mark out
seven 1-in. squares on the surface to be used for the top and
color the squares alternately white and black. Make six men by
sawing a curtain roller into pieces about 3/8 in. thick. Number
the pieces 1, 2, 3, 5, 6 and 7, and place them as shown in Fig. 1.
The puzzle is to make the first three change places with the last
three and

[Illustration: Position of the Men]

move only one at a time. This may be done as follows:

Move 1-Move No. 3 to the center.
Move 2-Jump No. 5 over No. 3.
Move 3-Move No. 6 to No. 5's place.
Move 4-Jump No, 3 over No. 6.
Move 5-Jump No. 2 over No. 5.
Move 6-Move No. 1 to No. 2's place.
Move 7-Jump No. 5 over No. 1.
Move 8-Jump No. 6 over No. 2.
Move 9-Jump No. 7 over No. 3.
Move 10-Move No. 3 into No. 7's place.
Move ll-Jump No. 2 over No. 7.
Move 12-Jump No, l over No. 6.
Move 13-Move No. 6 into No. 2's place.
Move 14-Jump No. 7 over No. 1.
Move 15-Move No. 1 into No, 5's place.

After the 15 moves are made the men will have changed places. This
can be done on a checker board, as shown in Fig. 2, using checkers
for men, but be sure you so situate the men that they will occupy
a row containing only 7 spaces.

** Gold Railroad Signals [189]

Covering railroad signals with gold leaf has taken the place of
painting on some roads. Gold leaf will stand the wear of the
weather for 15 or 20 years, while paint requires recovering three
or four times a year.

** How to Make a Bell Tent [190]

A bell tent is easily made and is nice for lawns, as well as for a
boy's camping outfit. The illustrations show a plan of a tent
14-ft. in diameter. To make such a tent, procure unbleached tent
duck, which is the very best material for the purpose, says the
Cleveland Plain Dealer. Make 22 sections, shaped like Fig. 3, each
10 ft. 6 in. long and 2 ft. 2 in. wide at the bottom, tapering in
a straight line to a point at the top. These dimensions allow for
the laid or lapped seams, which should be

double-stitched on a machine. The last seam sew only for a
distance of 4 ft. from the top, leaving the rest for an opening.
At the end of this seam stitch on an extra gusset piece so that it
will not rip. Fold back the edges of the opening and the bottom
edge of the bell-s
