The third person in the trio was Lottie. She was a small thing and did not know what adversity meant, and was much bewildered by the alteration she saw in her young adopted mother. She had heard it rumored that strange things had happened to Sara, but she could not understand why she looked different—why she wore an old black frock and came into the schoolroom only to teach instead of to sit in her place of honor and learn lessons herself. There had been much whispering among the little ones when it had been discovered that Sara no longer lived in the rooms in which Emily had so long sat in state. Lottie's chief difficulty was that Sara said so little when one asked her questions. At seven mysteries must be made very clear if one is to understand them.
 
"Are you very poor now, Sara?" she had asked confidentially the first morning her friend took charge of the small French class. "Are you as poor as a beggar?" She thrust a fat hand into the slim one and opened round, tearful eyes. "I don't want you to be as poor as a beggar."
 
She looked as if she was going to cry. And Sara hurriedly consoled her.
 
"Beggars have nowhere to live," she said courageously. "I have a place to live in."
 
"Where do you live?" persisted Lottie. "The new girl sleeps in your room, and it isn't pretty any more."
 
"I live in another room," said Sara.
 
"Is it a nice one?" inquired Lottie. "I want to go and see it."
 
"You must not talk," said Sara. "Miss Minchin is looking at us. She will be angry with me for letting you whisper."
 
She had found out already that she was to be held accountable for everything which was objected to. If the children were not attentive, if they talked, if they were restless, it was she who would be reproved.
 
But Lottie was a determined little person. If Sara would not tell her where she lived, she would find out in some other way. She talked to her small companions and hung about the elder girls and listened when they were gossiping; and acting upon certain information they had unconsciously let drop, she started late one afternoon on a voyage of discovery, climbing stairs she had never known the existence of, until she reached the attic floor. There she found two doors near each other, and opening one, she saw her beloved Sara standing upon an old table and looking out of a window.
 
"Sara!" she cried, aghast. "Mamma Sara!" She was aghast because the attic was so bare and ugly and seemed so far away from all the world. Her short legs had seemed to have been mounting hundreds of stairs.
 
Sara turned round at the sound of her voice. It was her turn to be aghast. What would happen now? If Lottie began to cry and any one chanced to hear, they were both lost. She jumped down from her table and ran to the child.
 
"Don't cry and make a noise," she implored. "I shall be scolded if you do, and I have been scolded all day. It's—it's not such a bad room, Lottie."
 
"Isn't it?" gasped Lottie, and as she looked round it she bit her lip. She was a spoiled child yet, but she was fond enough of her adopted parent to make an effort to control herself for her sake. Then, somehow, it was quite possible that any place in which Sara lived might turn out to be nice. "Why isn't it, Sara?" she almost whispered.
 
Sara hugged her close and tried to laugh. There was a sort of comfort in the warmth of the plump, childish body. She had had a hard day and had been staring out of the windows with hot eyes.
 
"You can see all sorts of things you can't see downstairs," she said.
 
"What sort of things?" demanded Lottie, with that curiosity Sara could always awaken even in bigger girls.
 
"Chimneys—quite close to us—with smoke curling up in wreaths and clouds and going up into the sky—and sparrows hopping about and talking to each other just as if they were people—and other attic windows where heads may pop out any minute and you can wonder who they belong to. And it all feels as high up—as if it was another world."
 
"Oh, let me see it!" cried Lottie. "Lift me up!"
 
Sara lifted her up, and they stood on the old table together and leaned on the edge of the flat window in the roof, and looked out.
 
Anyone who has not done this does not know what a different world they saw. The slates spread out on either side of them and slanted down into the rain gutter-pipes. The sparrows, being at home there, twittered and hopped about quite without fear. Two of them perched on the chimney top nearest and quarrelled with each other fiercely until one pecked the other and drove him away. The garret window next to theirs was shut because the house next door was empty.
 
"I wish someone lived there," Sara said. "It is so close that if there was a little girl in the attic, we could talk to each other through the windows and climb over to see each other, if we were not afraid of falling."
 
The sky seemed so much nearer than when one saw it from the street, that Lottie was enchanted. From the attic window, among the chimney pots, the things which were happening in the world below seemed almost unreal. One scarcely believed in the existence of Miss Minchin and Miss Amelia and the schoolroom, and the roll of wheels in the square seemed a sound belonging to another existence.
 
"Oh, Sara!" cried Lottie, cuddling in her guarding arm. "I like this attic—I like it! It is nicer than downstairs!"
 
"Look at that sparrow," whispered Sara. "I wish I had some crumbs to throw to him."
 
"I have some!" came in a little shriek from Lottie. "I have part of a bun in my pocket; I bought it with my penny yesterday, and I saved a bit."
 
When they threw out a few crumbs the sparrow jumped and flew away to an adjacent chimney top. He was evidently not accustomed to intimates in attics, and unexpected crumbs startled him. But when Lottie remained quite still and Sara chirped very softly—almost as if she were a sparrow herself—he saw that the thing which had alarmed him represented hospitality, after all. He put his head on one side, and from his perch on the chimney looked down at the crumbs with twinkling eyes. Lottie could scarcely keep still.
 
"Will he come? Will he come?" she whispered.
 
"His eyes look as if he would," Sara whispered back. "He is thinking and thinking whether he dare. Yes, he will! Yes, he is coming!"
 
He flew down and hopped toward the crumbs, but stopped a few inches away from them, putting his head on one side again, as if reflecting on the chances that Sara and Lottie might turn out to be big cats and jump on him. At last his heart told him they were really nicer than they looked, and he hopped nearer and nearer, darted at the biggest crumb with a lightning peck, seized it, and carried it away to the other side of his chimney.
 
"Now he KNOWS", said Sara. "And he will come back for the others."
 
He did come back, and even brought a friend, and the friend went away and brought a relative, and among them they made a hearty meal over which they twittered and chattered and exclaimed, stopping every now and then to put their heads on one side and examine Lottie and Sara. Lottie was so delighted that she quite forgot her first shocked impression of the attic. In fact, when she was lifted down from the table and returned to earthly things, as it were, Sara was able to point out to her many beauties in the room which she herself would not have suspected the existence of.
 
"It is so little and so high above everything," she said, "that it is almost like a nest in a tree. The slanting ceiling is so funny. See, you can scarcely stand up at this end of the room; and when the morning begins to come I can lie in bed and look right up into the sky through that flat window in the roof. It is like a square patch of light. If the sun is going to shine, little pink clouds float about, and I feel as if I could touch them. And if it rains, the drops patter and patter as if they were saying something nice. Then if there are stars, you can lie and try to count how many go into the patch. It takes such a lot. And just look at that tiny, rusty grate in the corner. If it was polished and there was a fire in it, just think how nice it would be. You see, it's really a beautiful little room."
 
She was walking round the small place, holding Lottie's hand and making gestures which described all the beauties she was making herself see. She quite made Lottie see them, too. Lottie could always believe in the things Sara made pictures of.
 
"You see," she said, "there could be a thick, soft blue Indian rug on the floor; and in that corner there could be a soft little sofa, with cushions to curl up on; and just over it could be a shelf full of books so that one could reach them easily; and there could be a fur rug before the fire, and hangings on the wall to cover up the whitewash, and pictures. They would have to be little ones, but they could be beautiful; and there could be a lamp with a deep rose-colored shade; and a table in the middle, with things to have tea with; and a little fat copper kettle singing on the hob; and the bed could be quite different. It could be made soft and covered with a lovely silk coverlet. It could be beautiful. And perhaps we could coax the sparrows until we made such friends with them that they would come and peck at the window and ask to be let in."
 
"Oh, Sara!" cried Lottie. "I should like to live here!"
 
When Sara had persuaded her to go downstairs again, and, after setting her on her way, had come back to her attic, she stood in the middle of it and looked about her. The enchantment of her imaginings for Lottie had died away. The bed was hard and covered with its dingy quilt. The whitewashed wall showed its broken patches, the floor was cold and bare, the grate was broken and rusty, and the battered footstool, tilted sideways on its injured leg, the only seat in the room. She sat down on it for a few minutes and let her head drop in her hands. The mere fact that Lottie had come and gone away again made things seem a little worse—just as perhaps prisoners feel a little more desolate after visitors come and go, leaving them behind.
 
"It's a lonely place," she said. "Sometimes it's the loneliest place in the world."
 
She was sitting in this way when her............
