The doctor looked fixedly at me for a full minute. Then he slowly telescoped his tall frame into an armchair, and sank down, a look of comic despair settling upon his face.

"O Lord!" he sighed heavily. "A strange man climbs through my parlor window to tell me, a bachelor, that my wife is locked up in the police station. What will happen next?"

And then we laughed together and made friends. The woman was just an ordinary lunatic.

I was late home from the office one evening the week my Christmas article was printed. My wife was waiting for me at the door, looking down the street. I saw that she had something on her mind, but the children were all right, she said; nothing was amiss. Supper over, she drew a chair to the fire and brought out a letter.

"I read it," she nodded. It was our way. The commonest business letter is to me a human document when she has read it. Besides, she knows so much more than I. Her heart can find a way where my head bucks blindly against stone walls.

The letter was from Jeanette Gilder, of the Critic, asking if I had thought of making my article into a book. If so, she knew a publisher. My chance had come. I was at last to have my say.

I should have thought I would have shouted and carried on. I didn't. We sat looking into the fire together, she and I. Neither of us spoke. Then we went up to the children. They slept sweetly in their cribs. I saw a tear in her eye as she bent over the baby's cradle, and caught her to me, questioning.

"Shall we lose you now?" she whispered, and hid her head on my shoulder. I do not know what jealous thought of authors being wedded to their work had come into her mind; or, rather, I do. I felt it, and in my heart, while I held her close, I registered a vow which I have kept. It was the last tear she shed for me. Our daughter pouts at her father now and then; says I am "fierce." But She comes with her sewing to sit where I write, and when she comes the sun shines.

Necessarily, for a while, my new work held me very close. "How the Other Half Lives" was written at night while the house slept, for I had my office work to attend to in the day. Then it was my habit to light the lamps in all the rooms of the lower story and roam through them with my pipe, for I do most of my writing on my feet. I began the book with the new year. In November it was published, and on the day it came out I joined the staff of the Evening Sun. I merely moved up one flight of stairs. Mulberry Street was not done with me yet, nor I with it.

I had had a falling out with the manager of the Associated Press Bureau,—the Tribune had retired from the copartnership some years before,—and during one brief summer ran an opposition shop of my own. I sold police news to all the papers, and they fell away from the Bureau with such hearty unanimity that the manager came around and offered to farm out the department to me entirely if I would join forces. But independence was ever sweet to me, and in this instance it proved profitable even. I made at least three times as much money as before, but I did it at such cost of energy and effort that I soon found it could not last, even with the phenomenal streak of good luck I had struck. It seemed as if I had only to reach out to turn up news. I hear people saying once in a while that there is no such thing as luck. They are wrong. There is; I know it. It runs in streaks, like accidents and fires. The thing is to get in the way of it and keep there till it comes along, then hitch on, and away you go. It is the old story of the early bird. I got up at five o'clock, three hours before any of my competitors, and sometimes they came down to the office to find my news hawked about the street in extras of their own papers.
