William Henry, 1911 Encyclopædia Britannica (1911)
“ In the event of accidentally getting hold of a bed of weeds, the swimmer should cease kicking and work with the arms, and the current will then take him through. If he tries to swim the weeds will entangle his legs and put him in an awkward plight. If he be carried away by a current in a river, he should select a spot on either bank and swim diagonally towards it, never minding where he has left bis clothes. When in the sea, the conditions are not always the same, though the general rule of swimming diagonally for shore also applies. ”
