At length the berg itself saved us from destruction. An immense mass broke off from that part which was beneath the surface of the sea, and this, a dozen times larger than the schooner, came rushing up within a few yards of us, sending a vast volume of foam and water flying from its sides. This rupture arrested the revolution, and the berg began to settle in the opposite direction. And now came another danger. A long tongue was protruding immediately underneath the schooner; already the keel was slipping and grinding upon it, and it seemed probable that we should be knocked up into the air like a foot-ball, or at least capsized. The side of our enemy soon leaned from us, and we were in no danger from the worse than hail-stone-showers which had driven us forward; so we sprang to the ice-poles, and exerted our strength in endeavoring to push the vessel off. There were no idle hands. Danger respects not the dignity of the quarter-deck. [Sidenote: PULLING FOR LIFE.] After we had fatigued ourselves at this hard labor without any useful result, the berg came again to our relief. A loud report first startled us; another and another followed in quick succession, until the noise grew deafening, and the whole air seemed a reservoir of frightful sound. The opposite side of the berg had split off, piece after piece, tumbling a vast volume of ice into the sea, and sending the berg revolving back upon us. This time the movement was quicker; fragments began again to fall; and, already sufficiently startled by the alarming dissolution which had taken place, we were in momentary expectation of seeing the whole side nearest to us break loose and crash bodily upon the schooner, in which event she would inevitably be carried down beneath it; as hopelessly doomed as a shepherd's hut beneath an Alpine avalanche. By this time Dodge, who had charge of the boat, had succeeded in planting an ice-anchor and attaching his rope, and greeted us with the welcome signal, "_Haul in_." We pulled for our lives, long and steadily. Seconds seemed minutes, and minutes hours. At length we began to move off. Slowly and steadily sank the berg behind us, carrying away the main-boom, and grazing hard against the quarter. But we were safe. Twenty yards away, and the disruption occurred which we had all so much dreaded. The side nearest to us now split off, and came plunging wildly down into the sea, sending over us a shower of spray, raising a swell which set us rocking to and fro as if in a gale of wind, and left us grinding in the _débris_ of the crumbling ruin.
