During these twenty years he had done as much work, in quantity, as his neighbors wanted; more than they would ever stop to look at, and more than his share. Merely in print, he thought altogether ridiculous the number of volumes he counted on the shelves of public libraries. He had no notion whether they served a useful purpose; he had worked in the dark; but so had most of his friends, even the artists, none of whom held any lofty opinion of their success in raising the standards of society, or felt profound respect for the methods or manners of their time, at home or abroad, but all of whom had tried, in a way, to hold the standard up. The effort had been, for the older generation, exhausting, as one could see in the Hunts; but the generation after 1870 made more figure, not in proportion to public wealth or in the census, but in their own self-assertion. A fair number of the men who were born in the thirties had won names--Phillips Brooks; Bret Harte; Henry James; H. H. Richardson; John La Farge; and the list might be made fairly long if it were worth while; but from their school had sprung others, like Augustus St. Gaudens, McKim, Stanford White, and scores born in the forties, who counted as force even in the mental inertia of sixty or eighty million people. Among all these Clarence King, John Hay, and Henry Adams had led modest existences, trying to fill in the social gaps of a class which, as yet, showed but thin ranks and little cohesion. The combination offered no very glittering prizes, but they pursued it for twenty years with as much patience and effort as though it led to fame or power, until, at last, Henry Adams thought his own duties sufficiently performed and his account with society settled. He had enjoyed his life amazingly, and would not have exchanged it for any other that came in his way; he was, or thought he was, perfectly satisfied with it; but for reasons that had nothing to do with education, he was tired; his nervous energy ran low; and, like a horse that wears out, he quitted the race-course, left the stable, and sought pastures as far as possible from the old. Education had ended in 1871; life was complete in 1890; the rest mattered so little!
