Some swimmers, at every stroke, raise not only their neck and
shoulders, but breast and body, out of the water. This, when habitual,
exhausts without any useful purpose. As an occasional effort, however,
it maybe useful in seizing objects above; and it may then best be
performed by the swimmer drawing his feet as close as possible under
his body, stretching his hands forward, and, with both feet and hands,
striking the water strongly, so as to throw himself out of it as high
as the hips.
