And he didn't. He was buried in the Potter's Field the next week. For once I was too late. The story of the last of my barons remains untold until this hour.

And now that this chapter, somewhat against my planning, has become wholly the police reporter's, I shall have to bring up my cause celebre, though that came a long while after my getting into Mulberry Street. I shall not have so good an opportunity again. It was the occasion of the last of my many battles for the mastery; but, more than that, it illustrates very well that which I have been trying to describe as a reporter's public function. We had been for months in dread of a cholera scourge that summer, when, mousing about the Health Department one day, I picked up the weekly analysis of the Croton water and noticed that there had been for two weeks past "a trace of nitrites" in the water. I asked the department chemist what it was. He gave an evasive answer, and my curiosity was at once aroused. There must be no unknown or doubtful ingredient in the water supply of a city of two million souls. Like Caesar's wife, it must be above suspicion. Within an hour I had learned that the nitrites meant in fact that there had been at one time sewage contamination; consequently that we were face to face with a most grave problem. How had the water become polluted, and who guaranteed that it was not in that way even then, with the black death threatening to cross the ocean from Europe?

I sounded the warning in my paper, then the Evening Sun, counselled the people to boil the water pending further discoveries, then took my camera and went up in the watershed. I spent a week there, following to its source every stream that discharged into the Croton River and photographing my evidence wherever I found it. When I told my story in print, illustrated with the pictures, the town was astounded. The Board of Health sent inspectors to the watershed, who reported that things were worse a great deal than I had said. Populous towns sewered directly into our drinking-water. There was not even a pretence at decency. The people bathed and washed their dogs in the streams. The public town dumps were on their banks. The rival newspapers tried to belittle the evil because their reporters were beaten. Running water purifies itself, they said. So it does, if it runs far enough and long enough. I put that matter to the test. Taking the case of a town some sixty miles out of New York, one of the worst offenders, I ascertained from the engineer of the water-works how long it ordinarily took to bring water from the Sodom reservoir just beyond, down to the housekeepers' faucets in the city. Four days, I think it was. Then I went to the doctors and asked them how many days a vigorous cholera bacillus might live and multiply in running water. About seven, said they. My case was made. There was needed but a single case of the dreaded scourge in any one of a dozen towns or villages that were on the line of travel from the harbor in which a half score ships were under quarantine, to put the metropolis at the mercy of an inconceivable calamity.

There was in all this no attempt at sensation. It was simple fact, as any one could see for himself. The health inspectors' report clinched the matter. The newspapers editorially abandoned their reporters to ridicule and their fate. The city had to purchase a strip of land along the streams wide enough to guard against direct pollution. It cost millions of dollars, but it was the merest trifle to what a cholera epidemic would have meant to New York in loss of commercial prestige, let alone human lives. The contention over that end of it was transferred to Albany, where the politicians took a hand. What is there they do not exploit? Years after, meeting one of them who knew my share in it, he asked me, with a wink and a confidential shove, "how much I got out of it." When I told him "nothing," I knew that upon my own statement he took me for either a liar or a fool, the last being considerably the worse of the two alternatives.

In all of this battlesome account I have said nothing about the biggest fight of all. I had that with myself. In the years that had passed I had never forgotten the sergeant in the Church Street police station, and my dog. It is the kind of thing you do not get over. Way back in my mind there was the secret thought, the day I went up to Mulberry Street, that my time was coming at last. And now it had come. I had a recognized place at Headquarters, and place in the police world means power, more or less. The backing of the Tribune had given me influence. More I had conquered myself in my fights with the police. Enough for revenge! At the thought I flushed with anger. It has power yet to make my blood boil, the thought of that night in the station-house.

It was then my great temptation came. No doubt the sergeant was still there. If not, I could find him. I knew the day and hour when it happened. They were burned into my brain. I had only to turn to the department records to find out who made out the returns on that October morning while I was walking the weary length of the trestle-work bridge across Raritan Bay, to have him within reach. There were a hundred ways in which I could hound him then, out of place and pay, even as he had driven me forth from the last poor shelter and caused my only friend to be killed.

Speak not to me of the sweetness of revenge! Of all unhappy mortals the vengeful man must be the most wretched. I suffered more in the anticipation of mine than ever I had when smarting under the injury, grievous as the memory of it is to me even now. Day after day I went across the street to begin the search. For hours I lingered about the record clerk's room where they kept the old station-house blotters, unable to tear myself away. Once I even had the one from Church Street of October, 1870, in my hands; but I did not open it. Even as I held it I saw another and a better way. I would kill the abuse, not the man who was but the instrument and the victim of it. For never was parody upon Christian charity more corrupting to human mind and soul than the frightful abomination of the police lodging-house, sole provision made by the municipality for its homeless wanderers. Within a year I have seen the process in full operation in Chicago, have heard a sergeant in the Harrison Street Station there tell me, when my indignation found vent in angry words, that they "cared less for those men and women than for the cur dogs in the street." Exactly so! My sergeant was of the same stamp. Those dens, daily association with them, had stamped him. Then and there I resolved to wipe them out, bodily, if God gave me health and strength. And I put the book away quick and never saw it again. I do not know till this day who the sergeant was, and I am glad I do not. It is better so.

Of what I did to carry out my purpose, and how it was done, I must tell hereafter. It was the source and beginning of all the work which justifies the writing of these pages; and among all the things which I have been credited with doing since it is one of the few in which I really bore a strong hand. And yet it was not mine which finally wrought that great work, but a stronger and better than mine, Theodore Roosevelt's. Even while I was writing this account we together drove in the last nail in the coffin of the bad old days, by persuading the Charter Revision Commission to remove from the organic law of the city the clause giving to the police the care of vagrants, which was the cause of it all. It had remained over in the Charter of the Greater New York in spite of our protests. It was never the proper business of the police to dispense charity. They have their hands full with repressing crime. It is the mixing of the two that confuses standards and makes trouble without end for those who receive the "charity," and even more for those who dispense it. You cannot pervert the first and finest of human instincts without corrupting men: witness my sergeant in Church Street and his Chicago brother.
