It was a most wonderful sight.
Barney saw various sea animals and fishes upon the bed of the sea.
It was an awful thing to think of.
Only the clear, transparent wall of the ice separated the chamber of the berg from the waters of the ocean.
Barney shivered as he reflected upon the possibility of that wall of ice breaking through and letting in the waters of the sea.
It would mean death to him.
This made the Celt feel a bit uncomfortable, and he began at once to look about for a way out of the place.
By the best good fortune he discovered an upward passage and at once took it.
It led upward, through various passages, and at times Barney had to cut niches in the ice to clamber up by.
But he kept at work.
