"I will let them know we are here;" and Mr. Atherton made two steps forward to the mouth of the defile. Almost at the same instant he levelled his rifle and fired, and one of the Maoris threw up his arms and fell back, the rest throwing themselves down instantaneously among the bushes, whence a moment later two or three shots were fired. But Mr. Atherton had stepped back, and he and the settler, lying down on the ground, worked themselves forward until by raising their heads they could command a view of the slope up to the mouth of the ravine. For a time all was silent. Presently Wilfrid's rifle spoke out, and a yell testified to the fact that the quick aim he had taken at a dark figure stealing among the bushes had been true. It was followed quickly by a general discharge of their pieces by the natives. The bullets rattled thickly against the rock, and cut leaves from the bushes behind which Wilfrid was lying, but he had drawn himself back a foot or two the moment he fired, and the balls passed harmlessly over him. Not so the missive despatched by Mr. Atherton in the direction of a puff of smoke from a bush some forty yards away, for the figure behind it remained still and immovable while the fray went on. For upwards of an hour the exchange of shots continued, and then the assailants were joined by fifteen other natives, who had been attracted to the spot by the sound of firing. "I expect they will pluck up their courage to make a rush now, Wilfrid," Mr. Atherton said. "If it had not been for these new arrivals I think they would have soon drawn off, for we must have diminished their numbers very considerably. Don't fire again for a bit; we had best keep our rifles loaded so as to be ready for them when they pluck up courage to charge. When they do, be sure you keep your revolver as a reserve for the critical moment." Five minutes later a tremendous yell rose in the air. The natives leaped to their feet from behind the bushes, fired their guns at their hidden foes, and then, tomahawk in hand, rushed forward.
