"And when, if I may ask?"

"When we think of returning."

"Returning!" cried Hatteras, "and who's thinking of that?"

"No one," answered Altamont; "but we shall stop somewhere, I suppose."

"And where?" asked Hatteras.

For the first time the question was fairly put to Altamont. The doctor would have given one of his arms to have put a stop to the discussion. Since Altamont made no answer, the captain repeated his question.

"And where?"

"Where we are going," answered the American, quietly.

"And who knows where that is?" said the peace-loving doctor.

"I say, then," Altamont went on, "that if we want to make use of the polar basin in returning, we can try to gain Kane's sea; it will lead us more directly to Baffin's Bay."
