Lily never liked to go to school, but she was ashamed to own it; so she went along with Sally, and was so amused with all she saw that she was glad she came. The brown loaf was hollow, and had no roof; and when she asked why they used a ruin, Sally told her to wait and see why they chose strong walls and plenty of room overhead. All round was a circle of very small biscuits like cushions, and on these the Bread-children sat. A square loaf in the middle was the teacher's desk, and on it lay an ear of wheat, with several bottles of yeast well corked up. The teacher was a pleasant, plump lady from Vienna, very wise, and so famous for her good bread that she was a Professor of Grainology. When all were seated, she began with the wheat ear, and told them all about it in such an interesting way that Lily felt as if she had never known anything about the bread she ate before. The experiments with the yeast were quite exciting,--for Fraulein Pretzel showed them how it would work till it blew the cork out, and go fizzing up to the sky if it was kept too long; how it would turn sour or flat, and spoil the bread if care was not taken to use it just at the right moment; and how too much would cause the loaf to rise till there was no substance to it. The children were very bright; for they were fed on the best kinds of oatmeal and Graham bread, with very little white bread or hot cakes to spoil their young stomachs. Hearty, happy boys and girls they were, and their yeasty souls were very lively in them; for they danced and sung, and seemed as bright and gay as if acidity, heaviness, and mould were quite unknown. Lily was very happy with them, and when school was done went home with Sally and ate the best bread and milk for dinner that she ever tasted. In the afternoon Johnny took her to the cornfield, and showed her how they kept the growing ears free from mildew and worms. Then she went to the bakehouse; and here she found her old friend Muffin hard at work making Parker House rolls, for he was such a good cook he was set to work at once on the lighter kinds of bread. "Well, isn't this better than Candy-land or Saccharissa?" he asked, as he rolled and folded his bits of dough with a dab of butter tucked inside. "Ever so much!" cried Lily. "I feel better already, and mean to learn all I can. Mamma will be so pleased if I can make good bread when I go home. She is rather old-fashioned, and likes me to be a nice housekeeper. I didn't think bread interesting then, but I do now; and Johnny's mother is going to teach me to make Indian cakes to-morrow." "Glad to hear it. Learn all you can, and tell other people how to make healthy bodies and happy souls by eating good plain food. Not like this, though these rolls are better than cake. I have to work my way up to the perfect loaf, you know; and then, oh, then, I'm a happy thing." "What happens then? Do you go on to some other wonderful place?" asked Lily, as Muffin paused with a smile on his face.
