lanks. Uprights of logs are placed at intervals along the
sides and ends and at the corners. Two and a half feet from either end a
second row of uprights is placed. The sides and inner ends are built up
to a height of 5 feet, the outer ends to 3 feet. The crib is pulled into
the water and towed to its position by a pier or wharf. It is sunk with
stones between the double ends until the floor is 3-1/2 feet below the
surface of the water at the pier end, and 4 feet below the surface at
the other end. It is held in position by being fastened to piles placed
at intervals around the edge. Steps lead down into the crib either from
the end of a pier, or from a wharf. As soon as a child can swim three
times around the crib without touching her foot to the bottom of the
crib or her hands to the sides, and can demonstrate three strokes, she
should be allowed to go into deep water, but should be carefully watched
for a while.

Land drill preceding the swimming lesson is very helpful. An expert
person should be made responsible for not more than twenty girls at one
time unless the girls are competent swimmers, and no one should be
allowed to interfere with the rules and regulations laid down by the
person in charge. Absolute obedience to all signals, rules and
regulations must be observed. An assistant counsellor should always be
in attendance at swimming lessons.

[Illustration: H. Swimming Crib as it would appear out of water. The
crib is 35' by 20', outside dimensions, with end pockets for stones,
2-1/2' each, leaving a swimming space of 30' by 20'. The idea for this
was planned and executed by the Engineers of the Park Commission of the
N.Y. and N.J. Interstate Park, for use in the camps in the Palisades
Park.]

Deep water swimmers should be able to pass the following requirements:
demonstrate three different strokes, breast, overarm and back stroke.
Swim under water. Demonstrate resuscitation. Throw a life-line
twenty-five feet for accuracy. Demonstrate diving, shallow, deep and
fancy diving. Rescue a drowning person twenty-five feet away from a
raft. Swim 50 yards with clothes on.

It is always advisable during a swimming period to have a boat well
manned near at hand. Bathing in fresh water, especially in spring-fed
lakes is not as exhilarating as salt water bathing, and twenty minutes
is considered the longest time a girl should stay in fresh water. Great
care should be taken that no child is a
