When Philip had left Millard in Second Avenue the evening before, the latter was puzzled. He had never seen Gouverneur so depressed and irritable. But when they had separated, Millard was relieved that he no longer had to force a conversation about things of no interest to himself, and that his thoughts were at length free to range where they would. He turned his footsteps towards his apartment, making a detour through Madison Square to lengthen the stroll. His interest in and affection for the family of his aunt was a fact so paradoxical to the rest of his life that it was in some sense his main secret. It was not a thing he should like to have explained to Philip Gouverneur, his bosom friend, for example. But that Phillida Callender was now in possession of the chief secret of his life gave him a sort of pleasure he had never known before. That she was in friendship with his aunt's family and a sharer in this off-color part of his existence made a sort of community of feeling between him and her. He turned the matter over in his mind, he went over in memory all parts of his encounter with her in his aunt's tenement, he dwelt upon the glow of surprise on her countenance, and in imagination he again took her hand in friendly greeting. He recalled every detail of the walk through Avenue C, in Tompkins Square, and then through the cross-streets. He made himself feel over again the pleasure he had felt in those rare moments when she turned her dark, earnest eyes toward him at some more than usually interesting moment in the conversation. This was the pleasant side of the reverie. For the rest, he was tormented with a certain feeling of unworthiness that had never troubled him so much before. The more he thought of the purposes, sweet, high, and disinterested, that moved her, the more was he pained at a sense of frivolity, or, at least, at a want of "worthwhileness" in his own aims. He was a communicant at St. Matthias's, and highly esteemed for his exemplary life and his liberality to the church. But the rector of St. Matthias's did not trouble himself, as Phillida did, about the lost sheep in the wilderness of the lettered avenues. His own flock, well washed and kempt, were much more agreeable subjects of contemplation.
