Benjamin Franklin,
Art of swimming rendered easy
(c. 1840–1850)
“ You strike the water with your right and left legs, when swimming on the back, at each extension of the legs, lifting them up out of the water one after another, you strike the water so that it starts into the air. Those who are most expert at this bring their chins towards their breast at each extension. There are some who, not satisfied with going so far, only, to perform the business more gracefully, lift up their legs higher than others, strike the water at cach extention, sometimes with the right leg, sometimes with the left, and at the same time turn the whole body. ”
