“And after a voyage to India, too! How funny! I am not a bit afraid, and I have never been out of England in my life. Are you afraid of being drowned?” chimed in Mellicent, with an air of superiority which goaded Peggy past endurance.

“I was not thinking of myself. It is possible sometimes to be nervous for another,” she blurted out, and the next moment wished her tongue had been bitten off before she had uttered such a rash remark; for what could Rob think, or his companions either, but that the person for whom she was anxious was present among them? They had not heard Mrs Asplin’s words of entreaty, or seen the strained expression on her face as she murmured, “Remember, dear! Oh, be sure to remember!”

She turned and walked along the shore by herself, clasping her hands in a passion of longing and pity.

“I gave her my promise, and I’ll keep it, whatever they think. It will be my fault if anything goes wrong. I know, and they don’t!”

It was one o’clock before the island was reached, for the row out took a long time, despite the fact that the amateur oarsmen were all fairly proficient at their work. Even the professor pulled with a will, while to see haughty Hector in his shirt sleeves, with his hair matted on his forehead, was indeed a novel experience. Arthur was stroke, and Mellicent sat in front and coached him in his duty, to the amusement of the company and his own unspeakable delight, and Eunice dabbled her hand in the water, and sent little showers of spray tossing up into the air. Every now and then, when Arthur made a reply to Eunice more professedly deferential than usual, her eyes met his, and they smiled at each other—that smile of happy, mutual understanding which had grown common between them in the last few months. Peggy intercepted one of the glances, and felt at once rejoiced and sorrowful; rejoiced because it was good to see Arthur started on the way she would have him go, sorrowful because she realised, as many another had done before her, that his gain must also be her loss, and that just in proportion as Eunice became necessary to him her own importance must decrease.

When all was said and done, however, it was impossible to indulge in low spirits in the hours that followed. Oh, the delights of that island, the dear, shingly beach with its little pools full of a hundred briny treasures, the long trails of seaweeds, which were credited with the gift of foretelling weather as well as any barometer; the tiny crabs that burrowed among the stones; the sea anemones, the jelly-fish, so innocent to regard, so deadly to encounter. They were all there, with tiny little pink-lined shells, and pebbles of marvellous transparency which must surely, surely, be worth taking to a lapidary to examine! What cries of delight followed the landing, what hasty summoning of the whole party to witness some fresh discovery; what trippings on slippery stones, and splashing of fresh white dresses! Then, too, the long-checked pangs of hunger asserted themselves, and would no longer be restrained, and the men were hardly allowed time to fasten the boat, go imperiously were they hurried on shore with the precious freight of hampers.

Lunch was spread beneath the tree, and was no sooner finished than Mellicent inquired, “When’s tea?” a request which the hearers felt bound to deride, though in reality it found an echo in every heart. Astonishing as it may appear, a picnic lunch invariably seems to create a longing for the cup which cheers, and on this occasion the sea air had a sleepifying influence which increased that desire.

“I re–ally think we had better have it soon. I can hardly keep from y–awning all the time!” cried Mrs Bryce, suiting the action to the word, and such was the result of infection that two pairs of hands went up to as many mouths even as she spoke.

“Very well, then, say four o’clock. Can’t possibly have it before then,” said Arthur, struggling vainly to keep his jaws together. “Oh, this will never do. Come down to the rocks, all of you, and get a good blow to freshen you up. I never saw such a company of sleepers!”

Eunice and Mellicent followed obediently enough, while the lovers seated themselves in a quiet corner, and Rob lay down on the sand beside one of the little pools, to watch the movements of the crawling insects. His trained glance was quick to understand the purport of what would have seemed aimless fittings to and fro to an ordinary observer, and soon out came notebook and pencil, and he was hard at work chronicling a dozen interesting discoveries. Peggy lingered behind to offer her help to Mrs Bryce, but that good lady, being secretly anxious to indulge in forty winks, seconded Hector Darcy’s protest in so emphatic a manner that she had no loophole for delay. She strolled with him down to the shore, following Arthur and his companions, but not so closely that there was not a distance of several yards between the two big stones which had been selected as resting-places. So far as privacy of conversation was concerned, the yards might have been miles, for the waves dashed up with a continual murmur, and the breeze seemed to carry the sound of the voices far out to sea. Peggy clasped her hands on her knee, and gazed before her with dreamy eyes. Her little face looked very sweet and thoughtful, and Hector Darcy watched her beneath the brim of his hat, and built his own castle in the air, a castle which had grown dearer and more desirable ever since his return to England. The opportunity for which he had been waiting had come at last, and surely it was an omen for good that it had come by the side of that sea which had witnessed their meeting; which, if all went well, would witness their start together on the new life!
