But when, at the end of that time, he put about, Ruth, who had scarcely spoken, straightened herself (she had been lying back indolently, with one hand behind her head), and watched the turning prow with regret. "_Must_ we go back so soon? Why?" "To look for sea-beans," answered Walter. "Are you aware, Mrs. Chase, of the awful significance of that New England phrase of condemnation, 'You don't know beans'? It will be said that _I_ don't know if I take you any farther. For the tide will soon turn, and the wind is already against us." But his tasks were not yet at an end; another idea soon took possession of his companion's imagination. "How wild Anastasia looks from here! I have never landed at this point. Can't we land now, just for a few moments? It would be such fun." "Won't it be more than fun, Mrs. Horace? A wild-goose--? Forgive the pun." On Anastasia there are ancient trails running north and south. Ruth, discovering one of these paths, followed it inland. "I wish we could meet something, I wish we could have an adventure!" she said. "There are bears over here; and there are alligators too at the pools. Perhaps this trail leads to a pool?" The surmise was correct; the path soon brought them within sight of a dark-looking pond, partly covered with lily leaves. Ruth, who was first (for the old Indian trail was so narrow that they could not walk side by side), turned back suddenly. "There really _is_ an alligator," she whispered. "He is half in and half out of the water. I am going to run round through the thicket, so as to have a nearer view of him." And hurrying with noiseless steps along the trail, she turned into the forest. He followed. "Don't be foolhardy," he urged. For she seemed to him so fearless that there was no telling what she might do. But when they reached the opposite side of the pool no alligator was visible, and Ruth, seating herself in the loop of a vine, which formed a natural swing, laughed her merriest. "You are an excellent actress," he said. "I really believed that you had seen the creature." "And if I had? They don't attack people; they are great cowards." "I have an admirable air of being more timid than she is!" he thought, annoyed. They returned towards the shore along a low ridge. On their way he saw something cross this ridge about thirty feet ahead of them--a slender dark line. He ran forward and looked down (for the ridge was four feet high).
