Henry James's health forced him to be a spectator of the war, in which his younger brothers fought. He went to Harvard in 1862 to study law, but was now beginning to feel a more and more irresistible call to take up letters as a profession, and the Harvard Law School left little or no direct impression upon him. He formed a close and valuable friendship with William Dean Howells, seven years his senior, and the pages of the _Atlantic Monthly_, of which Howells was then assistant editor, were open to him from 1865. He lived for the next four years in very poor health, and with no great encouragement from himself or others, always excepting Howells, at Cambridge, Massachusetts. Early in 1869 he ventured to return to Europe, where he spent fifteen months in elegant but fruitful vagabondage. There was much literary work done, most of which he carefully suppressed in later life. The reader will, however, discover, tucked away in the thirteenth volume of the Collected Edition, a single waif from this rejected epoch, the tale called _A Passionate Pilgrim_, written on his return to America in 1870. This visit to Europe absolutely determined his situation; his arrival in New York stimulated and tortured his nostalgia for the old world, and in May, 1872, he flew back here once more to the European enchantment. Here, practically, the biographical information respecting Henry James which has hitherto been given to the world ceases, for the fragment of _The Middle Years_, so far as can be gathered, contains few recollections which can be dated later than his thirtieth year. It was said of Marivaux that he cultivated no faculty but that _de ne vivre que pour voir et pour entendre_. In a similar spirit Henry James took up his dwelling in fashionable London lodgings in March, 1869. He had come from America with the settled design of making a profound study of English manners, and there were two aspects of the subject which stood out for him above all others. One of these was the rural beauty of ancient country places, the other was the magnitude--"the inconceivable immensity," as he put it--of London. He told his sister, "The place sits on you, broods on you, stamps on you with the feet of its myriad bipeds and quadrupeds." From his lodgings in Half Moon Street, quiet enough in themselves, he had the turmoil of the West End at his elbow, Piccadilly, Park Lane, St. James's Street, all within the range of a five minutes' stroll. He plunged into the vortex with incredible gusto, "knocking about in a quiet way and deeply enjoying my little adventures." This was his first mature experience of London, of which he remained until the end of his life perhaps the most infatuated student, the most "passionate pilgrim," that America has ever sent us.
