"Look!" broke in Fred, in sudden excitement.
To the unbounded amazement of captain, crew, and all the spectators, the very thing spoken of by Rob Carrol took place. The vast bulk of towering ice was seen to plunge downward with a motion, slow at first, but rapidly increasing until it dived beneath the waves like some enormous mass of matter cast off by a planet in its flight through space. As it disappeared, two-fold as much bulk came to view, there was a swirl of water, which was flung high in fountains, and the waves formed by the commotion, as they swept across the intervening space, caused the "Nautilus" to rock like a cradle.
The splash could have been heard miles away, and the iceberg seemed to shiver and shake itself, as though it were some flurried monster of the deep, before it could regain its full equilibrium. Then, as the spectators looked, behold! where was one of those mountains of ice they saw what seemed to be another, for its shape, contour, projections, and depressions were so different that no resemblance could be traced.
"She's all right now," remarked Jack Cosgrove, whose emotions were less stirred than those of any one else; "she's good for two or three thousand miles' voyage, onless she should happen to run aground in shoal water."
"What then would take place, Jack?" asked Fred.
"Wal, there would be the mischief to pay gener'ly. Things would go ripping, tearing, and smashing, and the way that berg would behave would be shameful. If anybody was within reach he'd get hurt."
Rob stepped up to the sailor as if a sudden thought had come to him. Laying his hand on his arm, he said, in an undertone:
"I wonder if the captain won't let us visit that iceberg?"
CHAPTER III
AN ALARMING SITUATION
The boldness of the proposition fairly took away the breath of the honest sailor. He stared at Rob as though doubting whether he had heard aright. He looked at the smiling youth from head to foot, and stared a full minute before he spoke.
