all at once I imagined I saw Shoal water ahead! the wave of coward Agony that surged through me then came near dislocating every joint in me. all my confidence in that Crossing vanished. I seized the bell-rope; dropped it, ashamed; seized it again; dropped it once more; clutched it Tremblingy once again; and pulled it so feebly that I could hardly hear the stroke myself.
