“Men in this place?” cried the reporter.

“We must avoid showing ourselves before knowing with whom we have to deal,” replied Cyrus Harding. “I trust that there are no natives on this island; I dread them more than anything else. Where is Top?”

“Top is on before.”

“And he doesn’t bark?”

“No.”

“That is strange. However, we must try to call him back.”

In a few moments, the engineer, Gideon Spilett, and Herbert had rejoined their two companions, and like them, they kept out of sight behind the heaps of basalt.

From thence they clearly saw smoke of a yellowish color rising in the air.

Top was recalled by a slight whistle from his master, and the latter, signing to his companions to wait for him, glided away among the rocks. The colonists, motionless, anxiously awaited the result of this exploration, when a shout from the engineer made them hasten forward. They soon joined him, and were at once struck with a disagreeable odor which impregnated the atmosphere.

The odor, easily recognized, was enough for the engineer to guess what the smoke was which at first, not without cause, had startled him.
