 suffering, that the erection of a single good tenement has the power to change, gradually but surely, the character of a whole bad block. It sets up a standard to which the neighborhood must rise, if it cannot succeed in dragging it down to its own low level.

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.
