"And yet it is so improbable that we must take a second look before pronouncing an opinion," said Clawbonny.
But the longer he looked, the more apparent became the fact. Hatteras was chagrined beyond measure. A European here, so near the Pole!
The footprints extended for about a quarter of a mile, and then diverged to the west. Should the travellers follow them further?
"No," said Hatteras, "let us go on."
He was interrupted by an exclamation from the Doctor, who had just picked up an object that gave still more convincing proof of European origin. It was part of a pocket spy-glass!
"Well, if we still had any doubts about the footmarks, this settles the case at once, at any rate," said Clawbonny.
"Forward!" exclaimed Hatteras so energetically, that instinctively each one obeyed, and the march was resumed forthwith.
The day wore away, but no further sign of the presence of suspected rivals was discovered, and they prepared to encamp for the night.
The tent was pitched in a ravine for shelter, as the sky was dark and threatening, and a violent north wind was blowing.
"I'm afraid we'll have a bad night," said Johnson.
