At last, panting and hot, she reached the sharp top, expecting to find Trevennack at his accustomed post on the very tallest pinnacle of the craggy little islet. But, to her immense surprise, her father wasn't there. His absence disquieted her. Cleer stood up on the fissured mass of orange-lichened rock that crowned the very summit, dispossessing the gulls who flapped round her as she mounted it; then, shading her eyes with her hand, she looked down in every direction to see if she could descry that missing figure in some nook of the crag. He was nowhere visible. "Father!" she cried aloud, at the top of her voice; "father! father! father!" But the only answer to her cry was the sound of the sea on the base, and the loud noise of the gulls, as they screamed and fluttered in angry surprise over their accustomed breeding-grounds. Alarmed and irresolute, Cleer sat down on the rock, and facing landwards for awhile, waved her handkerchief to and fro to attract, if possible, her father's attention. Then she scanned the opposite cliffs, beyond the gap or chasm that separated her from the mainland; but she could nowhere see him. He must have forgotten her and gone home to dinner alone, she fancied now, for it was nearly seven o'clock. Nothing remained but to climb down again and follow him. It was getting full late to be out by herself on the island. And tide was coming in, and the surf was getting strong--Atlantic swell from the gale at sea yesterday. Painfully and toilsomely she clambered down the steep path, making her foothold good, step by step, in the slippery crannies, rendered still more dangerous in places by the sticky spray and the brine that dashed over them from the seething channel. It was harder coming down, a good deal, than going up, and she was accustomed to her father's hand to guide her--to fit her light foot on the little ledges by the way, or to lift her down over the steepest bits with unfailing tenderness. So she found it rather difficult to descend by herself--both difficult and tedious. At last, however, after one or two nasty slips, and a false step or so on the way that ended in her grazing the tender skin on those white little fingers, Cleer reached the base of the crag, and stood face to face with the final problem of crossing the chasm that divided the islet from the opposite mainland. Then for the first time the truth was borne in upon her with a sudden rush that she couldn't get back--she was imprisoned on the island. She had crossed over at almost the last moment possible. The sea now quite covered two or three of her stepping-stones; fierce surf broke over the rest with each advancing billow, and rendered the task of jumping from one to the other impracticable even for a strong and sure-footed man, far more for a slight girl of Cleer's height and figure.
