Top sprang forwards, then almost immediately disappeared.

“He will get there!” said the reporter.

“Yes, and he will come back, the faithful animal!”

“What o’clock is it?” asked Gideon Spilett.

“Ten.”

“In an hour he may be here. We will watch for his return.”

The gate of the corral was closed. The engineer and the reporter re-entered the house. Herbert was still in a sleep. Pencroft kept the compresses always wet. Spilett, seeing there was nothing he could do at that moment, busied himself in preparing some nourishment, while attentively watching that part of the enclosure against the hill, at which an attack might be expected.

The settlers awaited Top’s return with much anxiety. A little before eleven o’clock, Cyrus Harding and the reporter, rifle in hand, were behind the gate, ready to open it at the first bark of their dog.

They did not doubt that if Top had arrived safely at Granite House, Neb would have sent him back immediately.

They had both been there for about ten minutes, when a report was heard, followed by repeated barks.
