Swimming Scientifically Taught (Illustrated Edition) (Dodo Press) Frank Eugen Dalton

"For an adult person to be unable to swim points to something like criminal negligence; every man, woman and child should learn. A person who can not swim may not only become a danger to himself, but to some one, and perhaps to several, of his fellow beings. Children as early as the age of four may acquire the art; none are too young, none too old. Doctors recommend swimming as the best allaround exercise. It is especially beneficial to nervous people. Swimming reduces corpulency, improves the figure, expands the lungs, improves the circulation of the blood, builds up general health, increases vitality, gives self-confidence in case of danger, and exercises all the muscles in the body at one time. As an aid to development of the muscular system, it excels other sports. Every muscle is brought into play.
