"If you were to spend as much time con-centrating as you do tearing about over the landscape, you would be more successful," declared Emma wisely, at which there was a laugh at Grace's expense. "I surely could not be more unsuccessful than I have been," replied Grace smilingly. The afternoon was passed in discussing their situation. While the girls were eager to be out trying to find Hippy, they believed that they were doing the wise thing in following the advice of their unknown friend, whose message had been tossed into their camp, so they remained in camp and waited. When night came and still no Hippy, the depression of the Overlanders increased and there was little conversation, each one appearing to be listening, Emma, with a faraway look in her eyes, now and then relapsing into deep thought. Emma was "con-centrating." The same arrangement for guarding the camp, as had been carried out the previous night, was again followed. This time, Grace took one side of the camp and Miss Briggs the other. Both hid in deep shadows, each with a rifle at her side and a revolver in its holster. Thus prepared they settled themselves for the night, all the other members of the party being in their tents and, supposedly, asleep. It was late when Grace and Elfreda were aroused by Washington talking, muttering in his sleep, then the nerves of the two girls leaped to attention as, out of the bushes on Miss Briggs' side of the camp, a twig snapped. It was accompanied by a sound that indicated the presence of a human being. "Who goes?" demanded Elfreda sharply. _Bang!_ Without giving the maker of the noise out there time to answer, she fired a shot from her revolver into the trees in that direction, but high enough to be certain that one underneath them would not be hit. Miss Briggs' shot brought instant results. "Hey there! Cut the gun!" howled Hippy Wingate. "It's Hippy!" breathed Grace, springing to her feet. "Don't shoot, Elfreda!" The two girls sprang up and waited. They were still cautious, but their companions, awakened by the shot, were not. Nora, Anne and Emma rushed out, demanding excitedly to know what the trouble was. At this juncture Hippy walked into the clearing. "Meet me with a pail of food! I'm starving!" he wailed. For the next few minutes there was excitement in the camp, Nora clinging to Hippy's neck laughing and crying, Emma standing a little aloof from them with a superior smile on her face, Anne, urging the wide-eyed Washington to start the fire and prepare coffee, and Grace seeking to quiet Nora so that they might hear Hippy's story. When the campfire blazed up and they saw his condition, Nora wept again. Hippy was hatless--his hat was out in the bushes where Grace, after finding it, had secreted it--his clothes were torn, he was hollow-eyed, and his head wore a lump that stood out prominently.
