"It seems to come from deep down in the berg.

What is it ?" "Must be the sea rushing through some crack, or possibly the rain-water and the water from the melted ice on top streaming down through some hole into the sea," said the captain.

"Well, I can't pretend to explain that.

I have an idea, however, that they resulted from the splitting off of large fragments of ice." On the whole, it was deemed most prudent to let the schooner lay where she was,--till daylight at least.

Planks were got up from below, and thrust down between the side and the ice to keep her from chafing against the sharp angles.
By this time it was near six o'clock, morning, and had begun to grow tolerably light.

The rain still continued, however, as did also the bellowings inside the iceberg.
