Next morning by eight o'clock all the remaining effects were on board, and the preparations for departure completed. But before starting the Doctor thought he would like to take a last look at the country and see if any further traces of the presence of strangers could be discovered, for the mysterious footmarks they had met with were never out of his thoughts. He climbed to the top of a height which commanded a view of the whole southern horizon, and took out his pocket telescope. But what was his astonishment, to find he could see nothing through it, not even neighbouring objects. He rubbed his eyes and looked again, but with no better result. Then he began to examine the telescope, the object glass was gone!
The object glass! This explained the whole mystery, foot-prints and all; and with a shout of surprise he hurried down the hill to impart his discovery to the wondering companions, who came running towards him, startled by his loud exclamation, and full of anxiety at his precipitate descent.
"Well, what is the matter now?" said Johnson.
The Doctor could hardly speak, he was so out of breath. At last he managed to gasp out-
"The tracks, footmarks, strangers."
"What?" said Hatteras, "strangers here?"
"No, no, the object glass; the object glass out of my telescope."

And he held out his spy-glass for them to look at.
"Ah! I see," said Altamont; "it is wanting."
