Time and education must solve that, like so many other problems which the slum has thrust upon us. They are the forces upon which, when we have gone as far as our present supply of steam will carry us, we must always fall back; and this we may do with confidence so long as we keep stirring, if it is only marking time, when that is all that can be done. It is in the retrospect that one sees how far we have come, after all, and from that gathers courage for the rest of the way. Thirty-two years have passed since I slept in a police station lodging house, a lonely lad, and was robbed, beaten, and thrown out for protesting; and when the vagrant cur that had joined its homelessness to mine, and had sat all night at the door waiting for me to come out,--it had been clubbed away the night before,--snarled and showed its teeth at the doorman, raging and impotent I saw it beaten to death on the step. I little dreamed then that the friendless beast, dead, should prove the undoing of the monstrous wrong done by the maintenance of these evil holes to every helpless man and woman who was without shelter in New York; but it did. It was after an inspection of the lodging rooms, when I stood with Theodore Roosevelt, then president of the police board, in the one where I had slept that night, and told him of it, that he swore they should go. And go they did, as did so many another abuse in those two years of honest purpose and effort. I hated them. It may not have been a very high motive to furnish power for municipal reform; but we had tried every other way, and none of them worked. Arbitration is good, but there are times when it becomes necessary to knock a man down and arbitrate sitting on him, and this was such a time. It was what we started out to do with the rear tenements, the worst of the slum barracks, and it would have been better had we kept on that track. I have always maintained that we made a false move when we stopped to discuss damages with the landlord, or to hear his side of it at all. His share in it was our grievance; it blocked the mortality records with its burden of human woe. The damage was all ours, the profit all his. If there are damages to collect, he should foot the bill, not we. Vested rights are to be protected, but, as I have said, no man has a right to be protected in killing his neighbor.
