When one lives in a row of houses, it is interesting to think of the things which are being done and said on the other side of the wall of the very rooms one is living in.  Sara was fond of amusing herself by trying to imagine the things hidden by the wall which divided the Select Seminary from the Indian gentleman's house.  She knew that the schoolroom was next to the Indian gentleman's study, and she hoped that the wall was thick so that the noise made sometimes after lesson hours would not disturb him.

"I am growing quite fond of him," she said to Ermengarde; "I should not like him to be disturbed.  I have adopted him for a friend.  You can do that with people you never speak to at all.  You can just watch them, and think about them and be sorry for them, until they seem almost like relations.  I'm quite anxious sometimes when I see the doctor call twice a day."

"I have very few relations," said Ermengarde, reflectively, "and I'm very glad of it.  I don't like those I have.  My two aunts are always saying, `Dear me, Ermengarde!  You are very fat.  You shouldn't eat sweets,' and my uncle is always asking me things like, `When did Edward the Third ascend the throne?' and, `Who died of a surfeit of lampreys?'"

Sara laughed.

"People you never speak to can't ask you questions like that," she said; "and I'm sure the Indian gentleman wouldn't even if he was quite intimate with you.  I am fond of him."

She had become fond of the Large Family because they looked happy; but she had become fond of the Indian gentleman because he looked unhappy.  He had evidently not fully recovered from some very severe illness.  In the kitchen--where, of course, the servants, through some mysterious means, knew everything--there was much discussion of his case.  He was not an Indian gentleman really, but an Englishman who had lived in India.  He had met with great misfortunes which had for a time so imperilled his whole fortune that he had thought himself ruined and disgraced forever.  The shock had been so great that he had almost died of brain fever; and ever since he had been shattered in health, though his fortunes had changed and all his possessions had been restored to him.  His trouble and peril had been connected with mines.

"And mines with diamonds in 'em!" said the cook.  "No savin's of mine never goes into no mines--particular diamond ones"-- with a side glance at Sara.  "We all know somethin' of THEM>." "He felt as my papa felt," Sara thought.  "He was ill as my papa was; but he did not die."

So her heart was more drawn to him than before.  When she was sent out at night she used sometimes to feel quite glad, because there was always a chance that the curtains of the house next door might not yet be closed and she could look into the warm room and see her adopted friend.  When no one was about she used sometimes to stop, and, holding to the iron railings, wish him good night as if he could hear her.

"Perhaps you can FEEL if you can't hear," was her fancy.  "Perhaps kind thoughts reach people somehow, even through windows and doors and walls.  Perhaps you feel a little warm and comforted, and don't know why, when I am standing here in the cold and hoping you will get well and happy again.  I am so sorry for you," she would whisper in an intense little voice.  "I wish you had a `Little Missus' who could pet you as I used to pet papa when he had a headache.  I should like to be your `Little Missus' myself, poor dear!  Good night--good night.  God bless you!"

She would go away, feeling quite comforted and a little warmer herself.  Her sympathy was so strong that it seemed as if it MUST reach him somehow as he sat alone in his armchair by the fire, nearly always in a great dressing gown, and nearly always with his forehead resting in his hand as he gazed hopelessly into the fire.  He looked to Sara like a man who had a trouble on his mind still, not merely like one whose troubles lay all in the past.

"He always seems as if he were thinking of something that hurts him NOW>, she said to herself, "but he has got his money back and he will get over his brain fever in time, so he ought not to look like that.  I wonder if there is something else."

If there was something else--something even servants did not hear of-- she could not help believing that the father of the Large Family knew it--the gentleman she called Mr. Montmorency.  Mr. Montmorency went to see him often, and Mrs. Montmorency and all the little Montmorencys went, too, though less often.  He seemed particularly fond of the two elder little girls--the Janet and Nora who had been so alarmed when their small brother Donald had given Sara his sixpence.  He had, in fact, a very tender place in his heart for all children, and particularly for little girls.  Janet and Nora were as fond of him as he was of them, and looked forward with the greatest pleasure to the afternoons when they were allowed to cross the square and make their well-behaved little visits to him.  They were extremely decorous little visits because he was an invalid.

"He is a poor thing," said Janet, "and he says we cheer him up.  We try to cheer him up very quietly."

Janet was the head of the family, and kept the rest of it in order.  It was she who decided when it was discreet to ask the Indian gentleman to tell stories about India, and it was she who saw when he was tired and it was the time to steal quietly away and tell Ram Dass to go to him.  They were very fond of Ram Dass.  He could have told any number of stories if he had been able to speak anything but Hindustani.  The Indian gentleman's real name was Mr. Carrisford, and Janet told Mr. Carrisford about the encounter with the little-girl-who-was-not-a-beggar.  He was very much interested, and all the more so when he heard from Ram Dass of the adventure of the monkey on the roof.  Ram Dass made for him a very clear picture of the attic and its desolateness-- of the bare floor and broken plaster, the rusty, empty grate, and the hard, narrow bed.

"Carmichael," he said to the father of the Large Family, after he had heard this description, "I wonder how many of the attics in this square are like that one, and how many wretched little servant girls sleep on such beds, while I toss on my down pillows, loaded and harassed by wealth that is, most of it--not mine."

"My dear fellow," Mr. Carmichael answered cheerily, "the sooner you cease tormenting yourself the better it will be for you.  If you possessed all the wealth of all the Indies, you could not set right all the discomforts in the world, and if you began to refurnish all the attics in this square, there would still remain all the attics in all the other squares and streets to put in order.  And there you are!"

Mr. Carrisford sat and bit his nails as he looked into the glowing bed of coals in the grate.

"Do you suppose," he said slowly, after a pause--"do you think it is possible that the other child--the child I never cease thinking of, I believe--could be--could POSSIBLY be reduced to any such condition as the poor little soul next door?"

Mr. Carmichael looked at him uneasily.  He knew that the worst thing the man could do for himself, for his reason and his health, was to begin to think in the particular way of this particular subject.

"If the child at Madame Pascal's school in Paris was the one you are in search of," he answered soothingly, "she would seem to be in the hands of people who can afford to take care of her.  They adopted her because she had been the favorite companion o............
