"There is something in that," Mr. Atherton said. "The Hau-Haus have always proved themselves even more merciless towards the friendly natives than towards the whites; and these men, being unarmed, might, even with the best disposition in the world, be afraid to come to the house. At any rate, I am glad those fellows have made off. You see, they were in a position to shoot any of us if they got the chance, while we were scarce in a position to return the compliment." "Why not?" James Allen asked. "Because, although we could have now no doubt whatever as to their intentions, they have committed no actual assault. They tried their best to push their way into the house, and when Wilfrid opposed them one of them drew his club; but they might say this was only done to frighten him, and that they had no thought of using it. If they had fired a shot, we should of course be justified in killing them; but were we to begin the shooting, the whole tribe they belong to would take it up, and there would be a cry for vengeance; and even if nothing were done at once, we should be marked down to be wiped out at the first opportunity. "We shall learn in a day or two whether the matter was serious or not," Mr. Atherton went on. "If there is anything like a general defection of the natives in these parts yours will not have been the only place threatened, and we shall hear of attacks on other settlers. If we do not hear of such attacks we can safely put it down that these four fellows were mere haphazard passers, like tramps at home, who were tempted by the fact that the house contained only two persons. In that case we need feel no further anxiety; for as you would be able to recognize them if you met them anywhere, they would not be likely to come near this part of the district again. At any rate I will set off with the boy here and one of the dogs, and will follow up their tracks and see if they have gone well away. I have no doubt they have done so; still, it will be more comfortable to make certain of it." "By the way, Bob," Wilfrid said, "don't you take those two dogs out again. I don't think they would be any good for hunting cattle, and would be much more likely to frighten and hunt them away than to help you to drive them in. At any rate they were bought as guards, and are to remain about the house. Shall I go with you, Mr. Atherton?"
