"Thank you. Who is Muffin?" asked Lily, feeling as if she had seen both these little people before, and liked them. "He was Ginger Snap once, but he's a Muffin now. We begin in that way, and work up to the perfect loaf by degrees. My name is Johnny Cake, and she's Sally Lunn. You know us; so come on and have a race." Lily burst out laughing at the idea of playing with these old friends of hers; and all three ran away as fast as they could tear, down the hill, over a bridge, into the middle of the village, where they stopped, panting, and sat down on some very soft rolls to rest. "What do you all do _here_?" asked Lily, when she got her breath again. "We farm, we study, we bake, we brew, and are as merry as grigs all day long. It's school-time now, and we must go; will you come?" said Sally, jumping up as if she liked it. "Our schools are not like yours; we only study two things,--grain and yeast. I think you'll like it. We have yeast to-day, and the experiments are very jolly," added Johnny, trotting off to a tall brown tower of rye and Indian bread, where the school was kept. 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 Fraeulein 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 sang, and seemed as bright and gay as if acidity, heaviness, and mould were quite unknown.
