The things as mentioned above do not modify the amount of the domestic slave trade as indicated by the statistical review in the text. If one should argue that the allowances we have made are not sufficient, we would ask him to take notice also that it is more than probable that most of the manumissions and escapes from slavery were in the border States, and to that extent lessens the amount of the apparent slave trade. It is impossible to be definite here, we can only approximate.] [Footnote 181: This about accords with Alexander, who said that by means of the internal trade about 4,000 or 5,000 arrived in the Southern States annually. Transatlantic Sketches, p. 230.] [Footnote 182: Between 1830 and 1840 the number of increase in South Carolina was only about 12,000, while during the previous decade it was about 57,000, if for no other reason showing her to be an exporting State.] [Footnote 183: Shaffner: The War in America, p. 256. (Ingraham): The Southwest, Vol. II., p. 237. It was rather hard to determine whether Missouri should be classed with selling or buying States. It is likely she did some of both as did some others. But practically all her increase after 1830 at least (aside from natural increase) seemed to be due to immigration from Kentucky and Virginia, though her increase was very large, we think she would rank as a selling State anyhow after 1830.] [Footnote 184: Census 1830 and 1840.] [Footnote 185: Chap. I., this volume.] [Footnote 186: Census 1840 and 1850.] [Footnote 187: Chap. I., this volume.] [Footnote 188: Census 1850 and 1860.] [Footnote 189: Chap. I., this volume.] CHAPTER IV WERE SOME STATES ENGAGED IN BREEDING AND RAISING NEGROES FOR SALE? As we now have a somewhat definite idea as to the amount of the domestic slave trade the next questions which naturally claim our attention are: Were some States consciously and purposely engaged in breeding and raising negroes for the Southern market, and also, what were the sources of supply for the trade? The former of these queries is, no doubt, the most controverted and difficult part of our subject. The testimony of travellers and common opinion generally seems to have been in the affirmative. A quotation or two will suffice to show the trend: The Duke of Saxe Weimar says, "Many owners of slaves in the States of Maryland and Virginia have ... nurseries for slaves whence the planters of Louisiana, Mississippi and other Southern States draw their supplies."[190]
