“A little home of my own in a shady quiet place with plenty of old trees, where I could work in peace. I have always fancied an old orchard. There might be a brook at one end——”

Molly smiled.

“He’s thinking of my orchard,” she thought.

“There must be hundreds of birds in my orchard,” went on the professor, “and the grass must always be thick and green, except perhaps when the drought comes and it can’t help itself——”

The six o’clock bell boomed out.

“Have an apple,” he said, taking two red apples from his pocket and giving one to each of the girls.

Then he opened the small oak door and stood politely aside while they passed out.
