"I think it is! I think it is _very_ pretty!" and the vicar could throw no further light on the subject than to say that he agreed with both. "It is useful then?" queried Peggy next; but this question fared no better than the first. "Not a bit," cried Mellicent. "It used to be, or, at least, _part_ of it did, but now it can do nothing at all but just--" "Be careful, dear! You will give them a clue. Oh yes, I think we can say it is useful. Its general characteristic is usefulness, and it will soon settle down again into its old ways." Peggy turned to Rob with a gesture of despair, and then started afresh on a different tack. "Is it an article in general use? Do you find one in every house?" "No, no!" "In our house?" Giggles from Mellicent, reproving glances from her father, a decided "No!" from Mrs Asplin. "In Rob's house?" "N-ot at present!" "Could you have more than one in any house at the same time?" Flutters of consternation and alarm--mysterious chuckles of laughter. "You _could_, but one at a time is enough for most people. Two or three would be rather embarrassing!" "Especially in a small house, because where should we sit in the evening? There would be no room for us!" said Mellicent meaningly, at which mysterious reply the listeners grew more mystified than ever. "It must be _very_ large!" they murmured thoughtfully. "What can it be? We shall never guess, so we might as well give it up at once and let you tell us. What _is_ the wretched thing?" "It's not wretched at all! It is very, very happy!

Peggy let her muscles slacken and leant back, limp and shapeless, against the cushions, while Rob, in his turn, gave a whistle of amazement. "An engaged couple! Oh, I say! Has that deep old Rex stolen a march on us behind our backs, and brought his _fiancee_?" "No, indeed! Nothing of the sort! Rex has no sweetheart except his old mother. I'd be delighted if he had--that's to say, if he could find a girl worthy of him, but I've never seen her yet. Guess again, dears! You are very hot, but it's not Rex." "Rosalind!" was Peggy's first thought; but no, it could not be Rosalind. That, of course, was impossible, while Oswald was already a married man, and Mellicent obviously out of the question. Who could it be? Peggy mentally summoned before her every member of the old merry party, and hazarded yet another suggestion. "Not Fraulein? Good old Fraulein, come back from Germany with a long- bearded professor in her train?" "Not Fraulein, no, but the professor might apply. Nearer home, child! You have not guessed every member of the family yet. You have not thought of--"
