There is nothing in the book with which I amused myself more than the house-hunting of the Marches when they were placing themselves in New York; and if the contemporary reader should turn for instruction to the pages in which their experience is detailed I assure him that he may trust their fidelity and accuracy in the article of New York housing as it was early in the last decade of the last century: I mean, the housing of people of such moderate means as the Marches. In my zeal for truth I did not distinguish between reality and actuality in this or other matters--that is, one was as precious to me as the other. But the types here portrayed are as true as ever they were, though the world in which they were finding their habitat is wonderfully, almost incredibly different. Yet it is not wholly different, for a young literary pair now adventuring in New York might easily parallel the experience of the Marches with their own, if not for so little money; many phases of New York housing are better, but all are dearer. Other aspects of the material city have undergone a transformation much more wonderful. I find that in my book its population is once modestly spoken of as two millions, but now in twenty years it is twice as great, and the grandeur as well as grandiosity of its forms is doubly apparent. The transitional public that then moped about in mildly tinkling horse-cars is now hurried back and forth in clanging trolleys, in honking and whirring motors; the Elevated road which was the last word of speed is undermined by the Subway, shooting its swift shuttles through the subterranean woof of the city's haste. From these feet let the witness infer our whole massive Hercules, a bulk that sprawls and stretches beyond the rivers through the tunnels piercing their beds and that towers into the skies with innumerable tops--a Hercules blent of Briareus and Cerberus, but not so bad a monster as it seemed then to threaten becoming.
