But Isabel's philosophy did not relieve Anne's fear. She called to Valeria, warningly, "You are very near the edge, Miss Morle; wouldn't it be safer to step back a little?" But Valeria would not. They were all noticing her at last. They should see how strong her nerves were, how firm her poise. The smokers below, too, were now observing her. She threw back her head, and hummed a little tune. If the edge did not crumble, she was, in truth, safe enough. To a person who is not dizzy, five inches of foot-hold is as safe as five yards. But--the edge did crumble. And suddenly. The group of women behind had the horror, of seeing her sway, stagger, slip down, frantically writhe on the verge half an instant, and then, with an awful scream, slide over out of sight, as her arm was wrenched from the little tree. Those below had seen it too. They sprang to their feet, and ran first forward, then round and up the hill behind. For she had not slipped far. The cliff jutted out slightly a short distance below the verge, and, by what seemed a miracle, the girl was held by this second edge. Eight inches beyond, the sheer precipice began, with the pile of broken stones sixty feet below. Anne was the first to discover this, reaching the verge as the girl sank out of sight; the others, shuddering, put their hands over their eyes and clung together. "She has not fallen far," cried Anne, with a quick and burning excitement. "Lie still, Valeria," she called down. "Close your eyes, and make yourself perfectly motionless; hardly breathe. We will save you yet." She took hold of the young tree to test its strength, at the same time speaking rapidly to the others. "By lying down, and clasping that tree trunk with one arm, and then stretching over, I can just reach her hand, I think, and seize it. Do you see? That is what I am going to try to do. I can not tell how strong this tree is; but--there is not a moment to lose. After I am down, and have her hand, do anything you think best to secure us. Either hold me yourselves or make ropes of your sacques and shawls. If help comes soon, we can save her." While still speaking, she threw herself down upon the edge, clasped one arm strongly round the tree trunk, and stretching down sideways, her head and shoulder over the verge, she succeeded in first touching, then clasping, the wrist of the girl below, who could not see her rescuer as she lay facing the precipice with closed eyes, helpless and inert. It was done, but only two girls' wrists as a link. The others had caught hold of Anne as strongly as they could. "No," said Isabel, taking command excitedly; "one of you hold her firmly, and the rest clasp arms and form a chain, all sitting down, to that large tree in the rear. If the strain comes, throw yourselves toward the large tree."
