o fasten a rope as shown in Fig. 1.

Attach the mast to the front crosspiece, also bowsprit, bracing
them both to the pontoons. A set of sails having about 300 sq. ft.
of area will be about right for racing. Two sails, main and fore,
of about 175 to 200 sq. ft. will be sufficient for cruising.

** Alligator Photo Mounts [424]

Rough alligator finished photograph mounts will not receive a good
impression from a die. If a carbon paper is placed on the mounts
before making the impression, a good clear imprint will be the
result.

** How to Attach a Sail to a Bicycle [425]

This attachment was constructed for use on a bicycle to be ridden
on the well packed sands of a beach, but it could be used on a
smooth, level road as well. The illustration shows the

[Illustration: Bicycle Sailing on a Beach]

main frame to consist of two boards, each about 16 ft. long, bent
in the shape of a boat, to give plenty of room for turning the
front wheel. On this main frame is built up a triangular mast, to
carry the mainsail and jib, having a combined area of about 40 sq.
ft. The frame is fastened to the bicycle by numerous pieces of
rope.

Sailing on a bicycle is very much different from sailing in a
boat, for the bicycle leans up against the wind, instead of
heeling over with it as the boat. It takes some time to learn the
supporting power of the wind, and the angle at which one must ride
makes it appear that a fall is almost sure to result. A turn must
be made by turning out of the wind, instead of, as in ordinary
sailing, into it; the boom supporting the bottom of the mainsail
is then swung over to the opposite tack, when one is traveling at
a good speed.

** Removing Iodine Stains [425]

A good way to chemically remove iodine stains from the hands or
linen is to wash the stains in a strong solution of hypo sulphite
of sodium, known as "hypo," which is procurable at any
photographic-supply dealer's or drug store.

There is no danger of using too strong a solution, but the best
results are obtained with a mixture of 1 oz. of hypo to 2 oz. of
water.

** Drying Photograph Prints without Curling [425]

Having made some photograph prints at one time that I wanted to
dry without the edges curling, I took an ordinary tin can and a
strip of clean cotton cloth, as wide as the can was long, and
wound it one turn around the can and then placed the prints, one
after
