"Hurrah! hurrah!" she shouted. "What did I tell you, Doris? There's something else behind here,--another cave, I guess. I'm going through. Are you going to follow?" Handing her candle to Doris, she scrambled through the narrow opening. And Doris, now determined to stick at nothing, set both candles on the ground, and pushed the struggling and resisting Genevieve in next. After that, she passed in the candles to Sally, who held them while she clambered in herself. And, once safely within, they stood and stared about them. "Why, Sally," suddenly breathed Doris, "this isn't a cave. It's a _cellar_! Don't you see all the household things lying around? Garden tools, and vegetables and--and all that? Where in the world can we be?" A great light suddenly dawned on her. "Sally Carter, what did I tell you? This cellar is Miss Camilla's. I know it. I'm _certain_ of it. There's no other house anywhere near Slipper Point. I _told_ you she knew about that cave!" Sally listened, open-mouthed. "It can't be," she faltered. "I'm sure we didn't come in that direction at all." "You can't tell how you're going--underground," retorted Doris. "Remember, the tunnel made a turn, too. Oh, Sally! Let's go back at once, before anything is discovered, and never, never let Miss Camilla or any one know what we've discovered. It's none of our business." Sally, now convinced, was about to assent, when Genevieve suddenly broke into a loud howl. "I won't go back! I won't go back--in that nas'y place!" she announced, at the top of her lungs. "Oh, stop her!" whispered Doris. "Do stop her, or Miss Camilla may hear!" Sally stifled her resisting sister by the simple process of placing her hand forcibly over her mouth,--but it was too late. A door opened at the top of a flight of steps, and Miss Camilla's astounded face appeared in the opening. "What is it? Who is it?" she called, obviously frightened to death herself at this unprecedented intrusion. Huddled in a corner, they all shrank back for a moment, then Doris stepped boldly forward. [Illustration: She led the others up the cellar steps] "It's only ourselves, Miss Camilla," she announced. "We have done a very dreadful thing, and we hadn't any right to do it. But, if you'll let us come upstairs, we'll explain it all, and beg your pardon, and promise never to speak of it or even think of it again." She led the others up the cellar steps, and into Miss Camilla's tiny, tidy kitchen. Here, still standing, she explained the whole situation to that lady, who was still too overcome with astonishment to utter a word. And she ended her explanation thus: "So you see, we didn't have the slightest idea we were going to end at this house. But, all the same, we sort of felt that this cave was a secret of yours and that we really hadn't any right to be interfering with it. But won't you please forgive us, this time, Miss Camilla? And we'll really try to forget that it ever existed."
