have missed it?"

"It may have been done just after Sir Giles died, and before she came to
the Manor."

"Where would they put it?"

"Possibly in the lantern room, inside some hiding-place they know of."

"Then, until we can find out the secret of the lantern room, it seems to
me we can't get any farther."

"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

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
