"And we don't even know that the treasure is still there, because it may be buried in the garden," groaned Lindsay. The whole affair of the lost legacy was most aggravating and tantalizing. They seemed so continually on the point of unravelling the mystery, only to find themselves again defeated and baffled. Cicely was tempted to throw it up altogether in despair, but Lindsay had a native obstinacy of disposition that could not bear to be beaten. "I shall go on trying as long as we're at Haversleigh, on that I'm entirely resolved," she declared. "I don't mean to give up until we're actually on our way to the station on breaking-up day." "And that's only three weeks off now," said Cicely. The summer term at the Manor had proved so enjoyable that the girls were not nearly so enthusiastic as usual for the advent of the holidays. Most of them felt a keen regret at leaving the beautiful old place, and bewailed the fact that the alterations at Winterburn Lodge were reported to be progressing favourably, and that the drains there would be in perfect order long before they need return in September. "Couldn't we have school here always instead of in London?" they suggested hopefully to Miss Russell. "No," said the headmistress; "there are many considerations which would make it impossible. Mrs. Courtenay and Monica will want to live in their own home again, and Haversleigh is too inconvenient a place for a permanency. We have managed wonderfully well for a few months with only Mademoiselle, but we certainly miss Herr Hoffmann's and Monsieur Guizet's classes, to say nothing of drawing and dancing lessons. Visiting masters cannot arrange to come so far away from town. There are no proper educational advantages to be had in the depths of the country." "We shall be sorry when it comes to good-bye," declared the girls. "We must make the most of our remaining time here then," said Miss Russell, "and try to see all we can in the neighbourhood before we go." The mistress's birthday, falling on the following Wednesday, offered a propitious opportunity for an excursion such as she suggested. The girls were accustomed to celebrate the occasion with some little festivity, and were delighted when it was arranged that they should visit the town of Appleford, about ten miles away. "There is the Dripping Well to see, and a fine old church," said Miss Russell. "I am sure we shall be able to spend a very pleasant afternoon there. We must ask Monica to come with us." There was some doubt at first as to whether Monica would be able to accept the invitation. She had missed her French lesson one day, and arrived at school late on the next, looking pale and upset. Mrs. Courtenay had been very ill, so she explained. The doctor had been sent for, and had given an unfavourable report. Naturally extra care and attention were needful, and who could give these so well as her own daughter? On the day of the picnic Monica turned up with rather an anxious face.
