* * * * * And so this task, too, has come to an end. Whatsoever a man soweth, that shall he also reap. I have aimed to tell the truth as I saw it. If this book shall have borne ever so feeble a hand in garnering a harvest of justice, it has served its purpose. While I was writing these lines I went down to the sea, where thousands from the city were enjoying their summer rest. The ocean slumbered under a cloudless sky. Gentle waves washed lazily over the white sand, where children fled before them with screams of laughter. Standing there and watching their play, I was told that during the fierce storms of winter it happened that this sea, now so calm, rose in rage and beat down, broke over the bluff, sweeping all before it. No barrier built by human hands had power to stay it then. The sea of a mighty population, held in galling fetters, heaves uneasily in the tenements. Once already our city, to which have come the duties and responsibilities of metropolitan greatness before it was able to fairly measure its task, has felt the swell of its resistless flood. If it rise once more, no human power may avail to check it. The gap between the classes in which it surges, unseen, unsuspected by the thoughtless, is widening day by day. No tardy enactment of law, no political expedient, can close it. Against all other dangers our system of government may offer defence and shelter; against this not. I know of but one bridge that will carry us over safe, a bridge founded upon justice and built of human hearts. I believe that the danger of such conditions as are fast growing up around us is greater for the very freedom which they mock. The words of the poet, with whose lines I prefaced this book, are truer to-day, have far deeper meaning to us, than when they were penned forty years ago: "--Think ye that building shall endure Which shelters the noble and crushes the poor?" APPENDIX. STATISTICS BEARING ON THE TENEMENT PROBLEM. Statistics of population were left out of the text in the hope that the results of this year's census would be available as a basis for calculation before the book went to press. They are now at hand, but their correctness is disputed. The statisticians of the Health Department claim that New York's population has been underestimated a hundred thousand at least, and they appear to have the best of the argument. A re-count is called for, and the printer will not wait. Such statistics as follow have been based on the Health Department estimates, except where the census source is given. The extent of the quarrel of official figures may be judged from this one fact, that the ordinarily conservative and careful calculations of the Sanitary Bureau make the death-rate of New York, in 1889, 25.19 for the thousand of a population of 1,575,073, while the census would make it 26.76 in a population of 1,482,273.
