For days Dick hunted all the turtles he saw lying on the water. At
last he got near enough to one to grab him before he dove. But he
got hold too far back, the reptile's head was already turned
downward and his flippers forced him rapidly forward. Dick hung on
as well as he could, which wasn't for long, for the strong rush of
