The key with the broken stem did not fit. A new lock had been put on. Next Ned went to a mantel over a gas grate and lifted the cover from a little ivory box which stood there. At the very bottom of the box, under buttons, pins, needles, and odds and ends, he found a key. This one was whole, and it was an exact duplicate of the one with the broken stem.
Ned had been in San Francisco three days, and Jimmie was not far away. On bringing the aeroplane to the plateau on the day of his return to Missoula he had found Ernest Whipple, Jack, Pat, Liu, and a small party of rangers anxiously awaiting him. Also “several tough ones waitin’ for an introduction,” as Jimmie put it. It seems that the fake foresters had returned to the cave after the fire in the cañon had burned itself out and had at once discovered that the prisoner had vanished, also that Liu, the Chinese boy, had disappeared with him.
There had been a long search for the missing boys, as the outlaws knew very well that the escape meant the bringing of officers to the caves, but they had not been discovered until a short time before the arrival of the aeroplane.
When Ned reached the plateau—in fact, before he reached it—he heard the whistling of bullets aimed at the big bird. The outlaws were trying to cripple the aeroplane and so give the riders a tumble. The boys landed in safety, however, and joined the others.
Seeing the boys thus reinforced, the outlaws had withdrawn, and the rangers had conducted them to a pass which led over the divide. So it was that Ned had left them, making their way down toward the Valley of the Wild Animals, where a large number of rangers were encamped, and where Frank was to come for them with the aeroplane as soon as Ned landed at Missoula.
There were numerous shots fired at the aeroplane as it mounted into the sky again, but no harm was done.
“If they had been shootin’ at that cat last night,” Jimmie said, in derision, “they would ’a’ been eaten alive.”
“They are nervous,” Frank said, “and don’t dare come out of their hiding places so as to get a good sight at us. They are afraid of the rangers, and afraid that we’ll drop a bomb or something of that sort down on them.”
This explanation of the bad marksmanship, as well as the failure of the outlaws to rush the aeroplane, was accepted by the boys, who had anticipated a fight with the fellows. It was afterwards learned, too, that there were only half a dozen outlaws in the group, and that they had been sent back to guard the caves and not to fight rangers unless they were attacked.
Ned had been very busy since his return to the city, having made many inquiries concerning Albert Lemon and his servant, the Japanese attendant who had given the boy such a chilly reception on the night of the first visit.
