"It is evident," said the lady who had been conversing with her when she had acted in a like manner on the first day of her arrival, "that she possesses a highly sensitive organism, which suddenly gives way when subjected to a strain too severe;" and she remained Van Berg of her former manifestation of weakness. He accepted this view as the most natural explanation that could be given. Chapter XV. Contrasts. Genuine and genial were the words of sympathy that were expressed on every side for the young lady who had been transforming the dull day into one of exceptional jollity. A deputation of ladies called upon her, but from within her locked door she confirmed the impression that it was a nervous shock, and that a few hours of perfect quiet would restore her. And it would seem that she was right, for she came down to supper apparently as genial and smiling as ever. Beyond a slight pallor and a little fulness about her eyes, Van Berg could detect no trace of her sudden indisposition. The remainder of the day was passed more quietly by the guests of the Lake House, but the force of Miss Burton's example did not spend itself at once, and on the part of some there was developed quite a marked disposition to make kindly efforts to promote the enjoyment of others. The unwonted exhilaration with which she had inspired her fellow guests was something they could scarcely account for, and yet the means employed had been so simple and were so plainly within the reach of all, as to suggest that a genial manner and an unselfish regard for others were the only conditions required to enable each one to do something to brighten every cloudy day. After Miss Burton's departure, the young people had the dance to themselves, their elders resuming the avocations and soberer pleasures from which they had been swept by an impulse evoked from their half-forgotten youth. When Van Berg joined Miss Mayhew again, he found her mother and Stanton trying to explain how it all came about. "There is no use of multiplying words," concluded Stanton; "Miss Burton is gifted with a mind, and she uses it for the benefit of others instead of tasking it solely on her own account, which is the general rule." At this moment a letter was handed to Mrs. Mayhew, which she read with a slight frown and passed to her daughter. It was from Mr. Mayhew, and contained but a brief sentence to the effect that his absence would probably be a relief, and therefore he would not spend the coming Sabbath with them.
