"Free from ice!" cried Shandon, interrupting the captain, "it's impossible!"
"You will notice, Shandon," observed Hatteras, quietly, while his eye lighted up for an instant, "that I quote both facts and authorities. I must add that in 1851, when Penny was stationed by the side of Wellington Channel, his lieutenant, Stewart, found himself in the presence of an open sea, and that his report was confirmed when, in 1853, Sir Edward Belcher wintered in Northumberland Bay, in latitude 76° 52', and longitude 99° 20'; these reports are indisputable, and one must be very incredulous not to admit them."
"Still, Captain," persisted Shandon, "facts are as contradictory—"
"You're wrong, Shandon, you're wrong!" cried Dr. Clawbonny; "facts never contradict a scientific statement; the captain will, I trust, excuse me."
"Go on, Doctor!" said Hatteras.
"Well, listen to this, Shandon; it results very clearly from geographical facts, and from the study of isothermal lines, that the coldest spot on the globe is not on the Pole itself; like the magnetic pole, it lies a few degrees distant. So the calculations of Brewster, Berghaus, and other physicists prove that in our hemisphere there are two poles of extreme cold: one in Asia in latitude 79° 30' N., and longitude 120° E.; the other is in America, in latitude 78° N., and longitude 97° W. This last alone concerns us, and you see, Shandon, that it is more than twelve degrees below the Pole. Well, I ask you why, then, the sea should not be as free from ice as it often is in summer in latitude 66°, that is to say, at the southern end of Baffin's Bay?"
"Well put," answered Johnson; "Dr. Clawbonny talks of those things like a man who understands them."
"It seems possible," said James Wall.
"Mere conjectures! nothing but hypotheses!" answered Shandon, obstinately.
"Well, Shandon," said Hatteras, "let us consider the two cases; either the sea is free from ice, or it is not, and in neither case will it be impossible to reach the Pole. If it is free, the Forward will take us there without difficulty; if it is frozen, we must try to reach it over the ice by our sledges. You will confess that it is not impracticable; having once come with our brig to latitude 83°, we shall have only about six hundred miles between us and the Pole."
