David was sitting in Morton's study, looking through the six years' accumulation of letters and documents, saving some, destroying others, when he came upon a dusty snap-shot photograph. Hands and eyes were arrested; Morton sank from his mind. Four persons sat in a little sailboat; their faces were wrinkled in sun-smiles; about and beyond them was the broad white blaze of the Sound. The four were Miss Chambers and her mother, Morton and himself. The day of the photograph ran its course again, hour by hour, in David's mind, and slowly rose other pictures of his acquaintance with Helen Chambers: of their first meeting three years before at a dinner at St. Christopher's Mission; of later meetings at St. Christopher's, where she had a club and where he was a frequent visitor; of the summer passed at St. Christopher's two years before, during the early part of which he, in Morton's stead, had aided her in selecting furnishings for a summer house given by her father for the Mission children; of two weeks at the end of that summer which he and Morton had spent at Myrtle Hill, the Chambers's summer home on the Sound. Since then he had seen her at irregular intervals, and their friendship had deepened with each meeting. She had interested his mind as no other woman had ever done. She had been bred in the conventions of her class, the top strata of the American aristocracy of wealth; all her friends, save those she had gained at the Mission, belonged in this class; and her life had been lived within her class's boundaries. Given these known quantities, an average social algebraist would have quickly figured out the unknown future to be, a highly desirable marriage, gowning and hatting, tea-drinking, dining, driving, calling, Europe-going, and the similar activities by which women of her class reward God for their creation--and in time, the motherhood of a second generation of her kind. But there was her character, which by degrees had revealed itself fully to David: her sympathy, her love of truth, a lack of belief in her social superiority, an instinct to look very clearly, very squarely, at things, a courage unconscious that it was courage, that was merely the natural action of her direct spirit--all these dissolved in a most simple, charming personality. It was these qualities (a stronger reprint of her mother's), in one of her position, that made David think her future might possibly be other than that contained in the algebraist's solution--that made him regard her as a potential surprise to her world. And Helen Chambers had interested not only David's mind. In moments when his courage had been high and his fancy had run riotously free, he had dared dream wild dreams of her. But now, as he gazed at the photograph, he sighed. In place and fortune she was on the level of the highest; he was far below--still only a straggler, obscure, barely keeping alive.
