"What is it, Wilfrid?" they exclaimed as they came up. "You fired the alarm-signal, did you not?" Both were breathless with the speed at which they had run. They had been engaged in felling when they heard the shot, and had thrown down their axes, run into the hut for their guns, and made for The Glade at the top of their speed. In a few words Wilfrid explained what had happened, and that there was every reason to believe that four hostile neighbours were lurking in the bush on the opposite side of the glade. The Allens at once volunteered to go up to the head of the clearing to warn the Grimstones. Returning to the point where they had left the forest, they made their way among the trees until they reached the upper end of the clearing; then they sat down and listened. In a few minutes they heard the sound of breaking twigs. "Here come the men," the elder Allen said; "the Maoris would come along noiselessly." Two or three minutes later the Grimstones came up at a run, accompanied by their two dogs. "This way," James Allen said. "What is it, sir?" Bob Grimstone gasped. "We were a long way in the woods when we thought we heard three shots. We were not quite sure about it, but we started back as fast as we could come. There is nothing wrong, I hope?" "Fortunately nothing has happened," James Allen replied; "but four strange Maoris came up to the house, and would certainly have murdered Mr. Wilfrid and his sister if they had not been prepared for them. Whether they are in the bush now or not I do not know; but we have come up to warn you not to go up the clearing, as, if they are there, they might pick you off as you did so. We must come down under shelter of the trees till we are opposite the house." In ten minutes they reached the house. Just as they did so Mr. Atherton appeared at the edge of the wood which they had just left. "Thank God you are all safe!" he said as he strolled up to the house. "Your three shots gave me a fright; but as I heard no more I was relieved, for the signal told that you had not been taken by surprise, and as there was no more firing it was clear they had drawn off." "But how did you get to that side of the clearing, Mr. Atherton?" "I followed the wood till within a few hundred yards of the clearing, as I made sure if there were hostile natives about they would be at the edge of the bush. Then I got down into the river and waded along the edge. The bank in front here was not high enough to hide me, though I stooped as much as I could; but I reckoned that all eyes would be fixed on the house, and it was not likely I should be noticed. And now, what is it all about? I am sure you would not have fired the signal unless there had been good cause for the alarm." Wilfrid related what had taken place. "Well done, Miss Marion!" Mr. Atherton said when he had finished. "It was lucky for your brother that you did not go with your father and mother this morning.
