I felt now that I had done my fair share towards attaining a virtuous subsistence, and so I waited tranquilly, and without undue enthusiasm, to see the rest of the world do its part in the matter. Meanwhile I read up on all sorts of imaginable cases, stayed at home all through my office hours, and at intervals explored the strange section of the town which lay to the south of my office. I do not suppose there is anything like it elsewhere. It was then, and still is, a nest of endless grog-shops, brothels, slop-shops, and low lodging-houses. You may dine here for a penny off of soup made from the refuse meats of the rich, gathered at back gates by a horde of half-naked children, who all tell varieties of one woful tale. Here, too, you may be drunk at five cents, and lodge for three, with men, women, and children of all colors lying about you. It is this hideous mixture of black and white and yellow wretchedness which makes the place so peculiar. The blacks predominate, and have mostly that swollen, reddish, dark skin, the sign in this race of habitual drunkenness. Of course only the lowest whites are here,--rag-pickers, pawnbrokers, old-clothes-men, thieves, and the like. All of this, as it came before me, I viewed with mingled disgust and philosophy. I hated filth, but I understood that society has to stand on somebody, and I was only glad that I was not one of the undermost and worst-squeezed bricks. You will hardly believe me, but I had waited a month without having been called upon by a single patient. At last the policeman on the beat brought me a fancy man, with a dog bite. This patient recommended me to his brother, the keeper of a small pawnbroking shop, and by very slow degrees I began to get stray patients who were too poor to indulge in uptown doctors. I found the police very useful acquaintances; and, by a drink or a cigar now and then, I got most of the cases of cut heads and the like at the next station-house. These, however, were the aristocrats of my practice; the bulk of my patients were soap-fat-men, rag-pickers, oystermen, hose-house bummers, and worse, with other and nameless trades, men and women, white, black, or mulatto. How they got the levies and quarters with which I was reluctantly paid, I do not know; that indeed was none of my business. They expected to pay, and they came to me in preference to the dispensary doctor two or three squares away, who seemed to me to live in the lanes and alleys about us. Of course he received no pay except experience, since the dispensaries in the Quaker City, as a rule, do not give salaries to their doctors; and the vilest of the poor will prefer a pay doctor, if he can get one, to one of these disinterested gentlemen who are at everybody's call and beck. I am told that most young doctors do a large amount of poor practice, as it is called; but, for my own part, I think it better for both parties when the doctor insists upon some compensation being made to him.
