He is thus completely wedged before and behind, and can only expand himself sideways by settling down on his stretched legs; but a sudden, violent pitch of the boat will often go far to topple him, because length of foundation is nothing without corresponding breadth. Merely make a spread angle of two poles, and you cannot standthem up. Then, again, it would never do in plain sight of the world's riveted eyes, it would never do, I say, for this straddling captain to be seen steadying himself the slightest particle by catching hold of anything with his hands; indeed, as token of his entire, buoyant self-command, he generally carries his hands in his trowsers' pockets; but perhaps being generally very large, heavy hands, he carries them there for ballast. Nevertheless there have occurred instances, well authenticated ones too, where the captain has been known for an uncommonly critical moment or two, in a sudden squall say--to seize hold of the nearest oarsman's hair, and hold on there like grim death.
