"I can never, never thank you enough, Mr. Herschel," Monica murmured, as Leslie gently pushed her to a heather-covered mound, and, bidding her rest a bit, threw himself on the grass beside her. "Please say no more," he entreated earnestly, "it was a mere nothing; I have always been a climber. But I am afraid this afternoon’s mishap will cause you to have unpleasant recollections of Gullane Head." A happy little smile played about Monica’s lips. "No, indeed, I shall always be glad----" she began, earnestly; but before she could finish her sentence, Elsa, whose whole attention had been taken up by Olive, came to express her delight at the happy ending to what had seemed an almost unavoidable accident. "How is Olive? I must go to her," said Monica, rising, vexed with herself for having forgotten her friend, even for a moment. "She is feeling more herself now," replied Elsa, "but I don’t believe she can walk a step, her legs tremble so, she says. And I don’t know how we shall get back to Mrs. Drury," and Elsa looked troubled. "We’ll manage that," said Marcus, cheerfully. "Come on, Herschel, let’s make a bandy chair, as the youngsters call it, and carry her between us." Olive demurred feebly, but it was very palpable when she tried to stand that she was far too exhausted to walk, so without more ado the two young men bore her off, Monica and Elsa bringing up the rear. The former was glad to slip her arm in Elsa’s, for she felt surprisingly shaky, and as they walked along the heather-grown cliff path, Monica learned how it was that Elsa had procured help; a question she had been longing to ask. It was soon explained--Elsa, going in search of the belated trio, had met Marcus and his friend leisurely strolling along the cliff, but not near enough to the edge to see what was happening. Fearing she knew not what, but instinctively feeling that they were in danger of some kind, Elsa told her fears to the young fellows, who at once proceeded to help in the search. With long strides they made for the cliff-side, in order to scan the shore, and were horrified to see the perilous position the two girls were in, less than twenty-five feet below them. A fisherman’s little shanty, presumably used in connection with lobster catching, close at hand, was hastily ransacked, and a stout coil of rope produced with intense satisfaction; and while young Herschel fastened on the rope, Elsa had encouraged the girls with words of hope. "What _will_ Mrs. Drury be thinking?" queried Monica, as they neared the Gullane Caves, following closely in the wake of the young men, who were still carrying their burden. "Oh, dear, what a lot of anxiety I do give people!" "I don’t think you must blame yourself specially, Monica dear," said Elsa gently; "you all seem to have agreed to attempt the climb together."
