Habits of living must be corrected and a crusade against ignorance and vice begun by society. I don't think I would miss it very far when I say that one-third of the colored people in our cities live in just such dwellings as I have described here; while most of the white population live in well-built houses in the healthy portions of the cities. Is there any surprise that there should be so great a disproportion in the mortality of the races? Compare the statistics of all the large cities and you will find that under similar conditions, this same proportion in mortality exists in the Northern and foreign cities, where the food and dwelling of the poor have the same difference. But this same difference exists nowhere in the world as it does in the South. It is almost impossible for a colored man to rent a respectable house anywhere in the cities; but the dark, low, damp, confined, ill-ventilated cellars and alley houses are rented for as much as comfortable quarters ought to bring. I don't wonder that the mortality of the Negro is so great; but I do wonder that it is not greater. Any other race of people would have been exterminated in twenty years. The remedy for the high death-rate is the enactment, and enforcement of laws against allowing the people to sleep in basements, cellars, old stables, alley houses, in low malarial sections of the cities, and making the penalty against the landlords so great, that they will not rent such places for dwellings. Regulate the kind of tenement houses and the number of persons who shall sleep in one room, the kind of food and rules for its preparation; break up these late church meetings in poorly ventilated houses, and the problem will be solved. The infant mortality will be reduced one-half when our people learn that the care of a good conscientious physician is necessary, from generation to development, and through the entire stage of adolescence; not so much to cure, as to prevent disease. Our whole system of medicine is now turning upon prevention rather than cure. When the public is educated up to the point of paying physicians to prevent as well as cure diseases, then, there will be less sickness and fewer epidemics. Then sanitary science, under the strict observance of hygiene, will reach perfection; the rude, gross habits of living will be corrected; a system of perfect drainage and ventilation will be inaugurated; pure air and fresh water supply will be furnished to every public and private house; only pure, unadulterated foods will be on the markets; every hotel, private and boarding-house will furnish properly prepared diets, and universal cleanliness will be the law.
