Nevertheless, the present conditions of negro mortality are frightful. They appear to be due primarily to ignorance and neglect in the care of children, and secondly, to an increase of dangerous diseases. The frequent statement that consumption was almost unknown among Negroes in slavery times is abundantly disproved by Hoffmann; but the disease is undoubtedly gaining, for much the same reason that it ravages the Indians in Alaska, namely, that the people now live in close houses which become saturated with the virus of the disease. Syphilis is also fearfully prevalent, and the most alarming statements are made by physicians who have practice or hospital service among the Negroes; but the testimony as to the extent of the disease is conflicting, and there are other race elements in the United States which are depleted by venereal disease. The blacks also suffer from the use of liquor, though drunkards are little known among the cotton hands; but drugs, particularly cocaine and morphine, are widely used. In one country store a clerk has been known to make up a hundred and fifty packages of cocaine in a single night. Notwithstanding the undoubtedly high death-rate, the birth-rate is so much greater that at every census the negro race is shown to be still growing; as Murphy says: "Whenever the Negro has looked down the lane of annihilation he has always had the good sense to go around the other way." The census of 1870 was so defective that it must be thrown out of account, but the negro population, which was about 4,400,000 in 1860, and 6,600,000 in 1880, had grown to 8,800,000 in 1900. It is true that the rate of increase is falling off both absolutely and in proportion to the white race. In the South Central group of states, which includes most of the Lower South, the population increased about forty-eight per cent from 1860 to 1880 and only thirty-nine per cent in the next double decade; while the white population has in both periods increased at about sixty per cent, with a rising ratio. The urban Negro has a high death-rate, not only in the South but in Northern cities; in Boston and Indianapolis the birth-rate of the Negroes does not keep pace with the deaths, and they would disappear but for steady accessions from the South. The Southern blacks on the land are doing better and are growing steadily; neither statistics nor observations support the theory that the Negro is dying out in the South; and comparatively slight changes in resort to skilled physicians, in the spread of trained nurses, in infants' food, may check the child mortality. On the other hand, any increase in thrift and in saving habits will almost certainly affect the size of families and diminish the average birth-rate.
