"I'm afraid we're neither of us as conscientious as you," said Muriel. "I used to prepare my Latin with it. I don't know how I could be so silly as to leave it lying about." "Perhaps it's as well you did," said Patty, gravely, "or it might never have been found out." "I'm dreadfully sorry now," said Muriel. "I wouldn't do it again. I'm so glad Miss Harper burnt it. It was most unfortunate it should be fixed upon you. I always told the girls you were innocent." "I don't think many of them believed it was mine." "A few did, or at any rate pretended they did. Well, I'll set it all straight when I get back to school. It'll be hateful to tell Miss Harper, but it's the one thing I can do to make up, and I will." Another half-hour had passed, and a slight breeze blowing from the sea began at length to disperse the fog, which, thinning a little, revealed the outline of the cliffs on the landward side. The sun had long ago set, but still showed such a bright glow on the western horizon, that it was light enough to see that the sandbank was almost clear, and the water flowing from it in broad channels. "I think we might leave our rock now," said Patty. "Perhaps if we wade we could reach the shore before it gets quite dark. Can you manage if I help you?" Muriel climbed painfully down, and taking Patty's arm, began to limp her way over the sands. "It's half-past ten," she said, "and our train was to leave at half-past six. All the others will have gone home ages ago. I don't know what we must do, even if we get to land." "Somebody's sure to be waiting for us," said Patty. "Why, I believe I can see a boat over there in the distance. Look! To your left, where the mist is blowing away." "It is!" exclaimed Muriel, in much excitement. "A fishing boat, with three men in it. Let us call as loudly as we can." The two girls joined in a wild "Halloo!" and to their great relief were at once answered by a shout in reply. The boat turned her course and made for the sandbank, and in a few minutes a bronzed old seaman had leaped over the gunwale and waded through the channel to their rescue. "Why, little misses, you've got yourselves in a fine fix!" he said, by way of greeting. "Here we've bin a-lookin' for you for a matter of four hours; just hangin' about in the fog, we was, and shoutin' every now and then on the off chance of your hearin' us. I ne'er thought we'd find you safe and sound, I didn't. Bin up the rock, you say? Ay, them rocks is never covered. If I'd only knowed you was there! We'd a' seen you long since, if it hadn't a' bin for the fog." He lifted Muriel in his arms, and, carrying her as easily as if she had been a baby, waded with her to the boat, returning afterwards for Patty. "You're nigh dead beat, both on you," he said, sympathetically. "It's give you a rare fright, I'll be bound, and us too! Your teacher's half crazed after you, poor thing! She'll be main glad to see you back, she will that!"
