None of them knew the color of the sky. Their eyes glanced level, and
were fastened upon the waves that swept toward them. These waves were of
the hue of slate, save for the tops, which were of foaming white, and
all of the men knew the colors of the sea. The horizon narrowed and
widened, and dipped and rose, and at all times its edge was jagged with
waves that seemed thrust up in points like rocks. Many a man ought to
have a bath-tub larger than the boat which here rode upon the sea. These
waves were most wrongfully and barbarously abrupt and tall, and each
froth-top was a problem in small-boat navigation.
