Unless an opening large enough to admit of the passage of the Explorer was found this would be an impossibility.
It was a horrible chance to contemplate.
But the darky did not give up hope.
He began at once to cautiously move the submarine boat about.
In vain he looked for an outlet from beneath the berg.
None seemed to exist.
Pomp felt desperate.
It looked as if the fate of the Explorer and its party was sealed.
The darky, in his desperation, began to count the chances of making a run into the walls of ice which blocked his passage.
It seemed to him the only way to get out of his present predicament.
