"Nothing very new here," said Harry at last, as the waves that kept coming in made the boat rise and fall gently; "there's another better cave than this close by. Let's go there; or what do you say to stopping here and having a smoke till the tide has risen and shut us in?" "Is there any risk of that?" said Pradelle anxiously. "Oh, yes, plenty." Leslie glanced at Louise and thought that it would be very pleasant to play protector all through the darkness till the way was open and daylight shone again. He caught her eyes more than once and tried to read them as he wondered whether there was hope for him; but so surely as she found him gazing rather wistfully at her, she hurriedly continued the collecting, pointing out one of the beautiful objects they sought beneath the surface, and asking Pradelle to shift the boat a little farther along. "All my vanity and conceit," said Leslie to himself with a sigh; "and why should I worry myself about a woman? I have plenty to do without thinking of love and marriage. If I did, why not begin to dream about pleasant, straightforward Madelaine Van Heldre? There can be nothing more than a friendly feeling towards Master Harry here." "Now then, sit fast," cried the latter object of his thoughts; "and if we are capsized, girls, I'll look after you, Maddy. Pradelle here will swim out with Louie, and I shall leave you to bring out the boat, Leslie. You can swim, can't you?" "A little," said the young man drily. Pradelle looked rather more green, for the light within the cave was of a peculiar hue, and he began to think uneasily of bathing out of a machine at Margate, holding on to a rope, and also of the effort he once made to swim across a tepid bath in town. But he laughed heartily directly after as he realised that it was all banter on his friend's part, while, in spite of himself, he gave a sigh of relief as, riding out on the crest of a broken wave, they once more floated in the sunshine. Ten minutes' careful rowing among the rocks, which were now four or five feet beneath the water, now showing their weedy crests above, brought them to the mouth of another cave, only approachable from the sea, and sending the boat in here, the collection went on till it was deemed useless to take more specimens, when they passed out again, greatly to Pradelle's satisfaction. "How's time?" said Harry. "Half-past four? Plenty of time. High tea at six. What shall we do--sail right out and tack, or row along here in the smooth water among the rocks?" "Row slowly back," said Louise: and Pradelle took an oar. At the end of half a mile he ceased rowing. "Tired?" said Harry. "No; I have a blister on my hand; that's all." "Come and pull, Leslie," said Harry. "You'd better steer, Louie, and don't send us on to a rock."
