They found themselves on a rocky ledge, with another drop ahead of them. At the bottom of this drop stood the guide, Art, and the pink girl, in daylight. The place was really the bottom of a little cañon, concealed in the woods, and a small river (not much more than a brook) flowed along it. On their right, to the east, however, the river vanished completely out of sight, into a great piled up mass of boulders. The leaders waited till all the party had arrived at the bottom, and then the guide led the way directly in among these boulders, the girls and women screaming and laughing as they followed. It became damp and cold and dark immediately. They entered a sort of cave, made by two rocks meeting overhead, and dropped down several feet to what felt like a sandy beach, though they could, at first, see nothing. But they could hear the water running beside them. “Look out here,” said the guide, “or you’ll step into the water. Follow me.” Alice, however, didn’t follow him. She was a frisky girl, and she wanted to see all there was to see, so she stepped to the left, and suddenly screamed. Peanut grabbed her hand and pulled her back. “Sh,” she whispered. “Up to the knees! But Mamma’d make me go back if she knew!” “What’s the matter, Alice?” called her mother. “She stubbed her toe,” Peanut answered, quickly. “Oh, you nice little liar!” chuckled Alice. Peanut was beginning to like her! The strange, underground path grew stranger and stranger. Sometimes they came out into daylight, and saw the sky and the walls of the cañon far above them, sometimes they stood in caves fifteen feet high, sometimes they had to cross the stream on planks, sometimes go up or down ladders. Finally they came to a place where the way was completely blocked, save for a small hole, which didn’t look more than two feet across. Somebody had painted above it, “Fat Man’s Agony.” “Don’t worry me a bit,” said Peanut. “Quick, let’s get through, and watch Mamma come out,” cried Alice. Art and the pink girl had disappeared into the hole already, Art going first. Alice lay down on her stomach and began to wriggle through after them, Peanut following. The guide remained behind to help the rest. The passage was on an incline, leading upward, and it seemed very long. It was certainly very dark. But they emerged presently (the tunnel coming out four feet above the ground, so one had to do quite an acrobatic stunt to gain his feet, if he was coming head foremost), and found Art and the pink girl waiting for them at the mouth of a cave. Behind them they could hear the screams and laughter of the rest, and Mamma’s voice exclaiming, “I _never_ can get through there, I tell you!” Alice put her face to the hole and shouted back, “Come on, Mamma, we’ll pull you through if you stick!” Then she looked at her feet. “Gee, Grace,” she called to the pink girl, “I’m soaked up to my knees!”
