"Now we mustn't laugh, girls, because it is a solemn moment," said Ellen Grant, though she did not succeed in looking very sober herself.

Betty was looking at Mary Grant's sin book, which had kept the record of two days, both with bad marks. If Mary had failed, what could impulsive Betty hope for? it was one of her worst temptations to make fun or to find petty faults in people. She did not know what her friends would think of her as time went on, but she meant to try very hard.

"Just think how lovely it will be if we learn never to say anything against any one! Perhaps we ought to make it a big club instead of a little one," but one of the girls said that people would laugh and would be watching them.

"Oughtn't we to ask Becky to belong?" It was difficult for Betty to ask this question, but she feared that her dear friend and neighbor's sharp eyes would detect the secret alliance, and Mary Beck was very hard to console when she was once roused into displeasure. Somehow Betty liked the idea of belonging to a club that Mary Beck did not know about. She was a little ashamed of this feeling, but there it was! The Grants and Lizzie refused to have Becky join, at any rate just now; and so Betty said no more. Perhaps it would be just as well at first, and she would be as careful as possible to gain good marks for her friend's sake as well as her own. Then the four members of the S. B. C. came back together into the village, and if the black cherry-tree heard their secret it never told. Whom should they meet as they turned the corner into the main street but Mary Beck herself, and Betty for one moment felt guilty of great disloyalty.

"We have been to walk a little way; I met the girls as I was going to the post-office, and we just went down the old road and sat under the cherry-tree," she hastened to explain, but Becky was in a most friendly mood and joined them with no suspicion of having been left out of any pleasure. Betty felt a secret joy in belonging to the club while Becky did not, and yet she was sorry all the time for Becky, who had a great pride in being at the front when anything important was going on. Becky liked to keep Betty Leicester to herself, and indeed the two girls were growing more and more fond of each other, though a touch of jealousy in one and a spirit of independence and freedom in the other sometimes blew clouds over their sunny spring sky. Mary Beck had a way of seeing how people treated her and rating them accordingly—a silly self-compassionate way of saying that one was good to her, and a surly suspicion of another who did not pay her an expected attention, and these traits offended Betty Leicester, who was not given to putting either herself or other people under a microscope. There was nothing morbid about Betty and no sentimentality in her way of looking at herself. Becky's sensitiveness and prejudice were sometimes very tiresome, but they made nobody half so miserable as they did Becky herself; the talk she had always heard at home was very narrowing; a good deal of fruitless talk about small neighborhood affairs went on continually and had nothing to do with the real interests of life. It was a house where there was very little to show for the time that was spent. Mary Beck and her mother let many chances for their own usefulness and pleasure slip by, while they said mournfully that everything would have been so different if Mary's father had lived. Betty Leicester was taught to do the things that ought to be done.

The Sin Book Club continued to be a profound secret, and was considered of great value. Some days passed without a second meeting of the members for reports, but they gave each other significant looks and tried very hard to gain the little crosses that were to mark a good day. Betty was in despair when evening after evening she had to put down a cipher, and it was a great humiliation to find how often she yielded to a temptation to say funny things about people. To be sure old Mrs. Max was an ugly old gossip, but Betty need not have confided this opinion to Serena and Letty as they happened to look out of the kitchen windows, to see Mrs. Max go by. Betty had succeeded in being blameless until past six o'clock that day, and it was the fifth day of trial; lost now, and black-marked like those that had gone before. She went back to the garden and sat down in the summer-house much dejected. The light that came through the grape and clematis leaves was dim and tinted with green; it was a little damp there too, and quite like a sorrowful little hermitage. It is very hard work trying to cure a fault. Betty did so like to make people laugh, and she was always seeing what funny things people looked like; and altogether life was much soberer if one could no longer say whatever came into one's head. She was sure that all funny personalities did not make people think the less of their fellows, but it seemed as if most, and the very funniest, did. Our friend dreaded the inspection of her sin book, but when the Grants and Lizzie French showed theirs too in solemn conclave there was only one good mark for the whole four. This was Ellen Grant's, who talked much less than either of the others and so may have found that silence cost less effort.

"Even if we never succeed it will make us more careful," Lizzie French said, trying to keep up good courage.

"I keep wishing that Mary Beck belonged;" urged Betty loyally, but the others were resolute and insisted, nobody could tell exactly why, that Becky would spoil it all.

Betty was valiant enough in case of open war, but she hated heartily—as who does not hate?—a chilling atmosphere of disapproval, in which no good-fellowship can flourish. Of course the club soon betrayed its common interest, and because Mary Beck was unobservant for the first week or two, Betty took little pains to conceal the fact that she and the Grants had a new interest in common. Then one day Becky did not come over, though the white handkerchief was displayed betimes; and when, as soon as possible, Betty hurried over to see what the matter was, Becky showed unmistakable signs of briefness and grumpiness of speech, and declared that she was busy at home, and evidently did not care for the news that an old Æolian harp had been discovered on a high upper shelf and carried to one of the dormer windows, where it was then wailing. The plaintive strains of it would have suited Becky's spirit and temper of mind excellently. It did not occur to Betty until she was going home, disappointed, that the club was beginning to make trouble; then her own good temper was spoiled for that day, and she was angry with Becky for thinking that she had no right to be intimate with anybody else. So serious a disagreement had never parted them before. Betty Leicester assured herself that Mary knew she was fond of her and liked to be with her best, and that ought to be enough. The Æolian harp was quite forgotten.

Later in the day Betty happened to look across the street as she was shutting the blinds in the upper hall, and saw Mary Beck come proudly down her short front walk with her best hat on and go stiffly away without a look across. The sight made her feel misunderstood and lonely; and one minute later she was just going to shout to Becky when she remembered that it was a far cry and would wake the aunts from their afternoon naps. Then she ran lightly down the wide staircase and all the way to the gate and called as loud as she could, "Mary! Mary!" but either Becky was too far away or would not turn her proud head. There were some other persons in the street, who looked with surprise and interest to see where such an eager shout came from, but Betty Leicester had turned toward the house again with a heartful of rage and sorrow. It seemed to be the sudden and unlooked-for end of the summer's pleasure. When Aunt Barbara waked she asked Betty, being somewhat surprised to find her in the house alone, to go to the other end of the village to do an errand.
