The next day Miss Ketchum thanked her for them, and explained to her that she would have to set some of them at liberty again, since she had some of a good many of the varieties, and two of each were all that she could take care of; but Ruby was delighted to hear that Miss Ketchum had never had some of the specimens before, and that she was quite sure that they would make beautiful butterflies.

After this Ruby and Miss Ketchum were as good friends as Agnes had always been with her teacher, and Miss Ketchum found it a great help to have two little girls, instead of one, upon whom she could always rely for good behavior, and who could be trusted never to wilfully annoy her.

She had a great many treasures in her room that had been brought to her from China by a brother who had been a missionary there, and she was always glad to have Agnes and Ruby come and pay her a little visit, and look at whatever they wished. She knew they could be trusted to handle things carefully and not be meddlesome, and many a happy hour the two girls spent there. Miss Ketchum's room was a very large room, as it was the only one over the school-house, so she had plenty of space to keep all her curiosities and her pets.

There was a little cupboard that stood in a corner, just as if it had been built for that particular space, and in this corner closet Miss Ketchum kept a little tin of delicious seed-cakes, and some cups and saucers, and pretty little plates with butterflies, and mandarins, and pagodas, and Chinese beauties upon them; and very often when the girls came to see her she would open this cupboard and they would have a little treat, which seemed all the more delightful because the plates were so odd. There was an open fireplace in the room, and when the days were cold and there was a snapping, blazing wood-fire, they used to ask Miss Ketchum if they might not bring their chestnuts and roast them in the hot ashes.

Miss Ketchum knew a great many stories, too, and sometimes, on Saturday afternoon, when the children had plenty of time, and would surely not have to hurry away in the most interesting part of the story, she would lean back in her big rocking-chair, and with the little girls sitting on ottomans, one each side of her, she would tell them delightful stories about when she was a little girl and went to school. Ruby and Agnes were glad that they did not live then, when there was no whole holiday on Saturday, but they were very much interested in hearing all that Miss Ketchum had to tell them, and in comparing the things that she did when she went to school with what they did themselves.

Altogether Miss Ketchum was a very delightful friend to have, if, she was a little forgetful sometimes, and did like caterpillars; but Ruby and Agnes grew almost as fond of her pets as she was herself, as they learned how much there was of interest about them. They looked forward quite eagerly to the time when, instead of the ugly worm that had woven a chrysalis about himself and gone to sleep for the winter, there should burst forth a beautiful butterfly. It made them more careful not to hurt creeping things, and if they found a brown worm crawling about where he might be stepped upon, the girls would always pick him up carefully upon a stick or leaf and put him in a safe place where he might keep out of danger.

CHAPTER XX.

PERSIMMONS.

The September days passed away and the October days came and found Ruby both happy and good. She had not forgotten her home nor her dear mother and father, but she was learning to love her new home very dearly, and she had tried so hard to be good and give the teachers as little trouble as possible that they were all very fond of her. She found her lessons very pleasant, and as she loved study and was ambitious to always have perfect lessons she was very near the head in all her classes.
