“I say, Edgar, though we are sent to bed, we are not bound to go to sleep,” exclaimed Rob. “I vote that you and I keep watch at the window, turn and turn about. I have got one of Paul’s pistols, and if any blacks come we will shoot them.”

“But they would have to come fearfully close to do that, and I don’t think I could fire at a man with a spear in his hand, grinning horribly at me out of the dark.”

It is easy to imagine the picture Edgar conjured up.

“That’s the very time I would shoot,” answered Rob; “if I did not, he might hurl the spear and stick it into me.”

“Keep quiet, you fellows,” growled out Hector, who was awakened by their talking, though he did not hear what they said. They were silent till they thought that he was again asleep.

“If you’re afraid I’m not,” said Rob. “I will take the first watch, and I will call you when it’s time for you to look out, and then you can rouse me up if you see anything, and I will be alongside you in a moment.”

Edgar having agreed to this, Rob sat himself down on a stool, with his head just above the window-sill, on which it soon dropped. He was, in reality, fast asleep, though all the time he thought that he was keeping a very bright lookout, and that he saw savages creeping up in the distance, but that he was waiting to give the alarm until they should get somewhat closer. At last he awoke with a most uncomfortable crick in his neck, and found, to his surprise, that the dawn had broken. Hector and Edgar were sleeping soundly, and believing that no blacks would venture near the house by daylight, he wisely crept into his bunk, where he lay until roused by the sound of the gong which summoned the family to prepare for breakfast.

The night had passed without any appearance of the blacks, and the captain, who had searched round the house in every direction, could find no traces of them. He began, indeed, to suspect that Rob must have been mistaken in supposing that he had seen a lurking native in the scrub. He and Mr Berrington, followed by Bruce, after breakfast made a long circuit through the scrub, and visiting the spot Rob described, the captain had reason to change his opinion, for he at length found traces of natives, and the remains of a fire, where they must have encamped that very night. This satisfied him that the precautions he had taken had not been useless, but, as far as he could judge, the blacks had retreated to the westward. The chief anxiety of the family was now about Harry and Mr Hayward, who had not yet returned. Late in the day, however, Rob and Edgar, who were patrolling round and round the house under the idea that they were keeping guard, saw Harry galloping up to them.

“Well, what news?” shouted Rob. “We have been expecting the blacks all day, but they have not come yet. Have you fallen in with them?”

“Yes, indeed we have!” answered Harry, “and had a desperate fight too. We killed some of them, and the rest ran off. Lieutenant Bertram, of the police, believes that they will still remain lurking in the neighbourhood, and has come on with some of his men to be ready to act
