“Now there’s something to explain the bullet!” exclaimed Pencroft.

“A castaway!” replied Herbert.

“Wounded, perhaps!” said Neb.

“Or dead!” added the reporter.

All ran after the dog, among the tall pines on the border of the forest. Harding and his companions made ready their firearms, in case of an emergency.

They advanced some way into the wood, but to their great disappointment, they as yet saw no signs of any human being having passed that way. Shrubs and creepers were uninjured, and they had even to cut them away with the axe, as they had done in the deepest recesses of the forest. It was difficult to fancy that any human creature had ever passed there, but yet Top went backward and forward, not like a dog who searches at random, but like a dog being endowed with a mind, who is following up an idea.

In about seven or eight minutes Top stopped in a glade surrounded with tall trees. The settlers gazed around them, but saw nothing, neither under the bushes nor among the trees.

“What is the matter, Top?” said Cyrus Harding.

Top barked louder, bounding about at the foot of a gigantic pine. All at once Pencroft shouted,—“Ho, splendid! capital!”

“What is it?” asked Spilett.
