We believe, therefore, that the census of 1850, if truly taken, will exhibit a much larger annual unnatural decrease of the slave-population in the exporting States. This decrease, whatever it may really be, has not been owing to manumissions. It has not been caused by slaves running away. For the effects of both these causes, the surplus over 40,000 would be a liberal allowance. This unnatural decrease must, then, be caused by the slave-trade, and the migration of planters with their slaves. The fact is beyond all question, that every year forty thousand men, women, and children are torn from their homes and friends, and driven to the South and West. So truly did the Rev. Theodore Clapp speak (Sermon, p. 46), when he declared, "Slaves possess the inappreciable benefits which grow out of the endearing ties of friendship, kindred, sympathy, and the whole class of domestic affections. Parents and children, husbands and wives (it is true), are sometimes separated by being involved in those calamities which sweep away the possessions and prosperity of the master. But, take it all in all, they are as free and undisturbed in the enjoyment of their domestic relations, as the white inhabitants of the Northern States"! Forty thousand fathers, mothers, brothers, sisters, and children are every year carried from the places of their birth, like so many cattle, although the terrible fact is well known that at least one fourth of them must die in the process of acclimation![S] So very tender is man of man, when he holds his brother in slavery, and makes merchandise of his sister! So eager is the soul-driver to coin his brother's blood into dollars! So ready are those whom "God has appointed masters" to sacrifice the lives of one fourth of those committed to their charge, in order greatly to advance the market value of the survivors!
We have no data from which to infer the number of planters who go South with their slaves. But, allowing that five hundred thus remove, and that on an average they have ten slaves each (proper estimates we believe), we have left thirty-five thousand as the number of human beings who are every year sold to the speculators in human flesh!
Now, Mr. Barnes's "lot" of his fellow-creatures averaged in value over five hundred dollars apiece; and those were times when, from his account, the market was glutted, and the prices accordingly low. "Young and likely" negroes are more easily acclimated, and are better able to work, than others. Consequently, they are the ones most sought after by judicious traders. We should consider five hundred dollars for a young, healthy negro, warranted sound, as really a low price. But, if we suppose the slaves annually exported to be worth less than any of Mr. Barnes's lot,--considering them as worth only $450 apiece,--we have, as _the sums of money every year invested in the trade in slaves, the very moderate sum of fifteen millions seven hundred and fifty thousand dollars_! This is _exclusive_ of the cost of all the private jails, of transportation by sea and land, food, wages of drivers, &c.; which cannot but very largely increase this sum. This sum, $15,750,000, would, in less than three years, double the number of miles of railroad which were in operation in all the Southern States in 1846 (Parker's "Letter on Slavery," p. 52). It would, in only two years, more than double in length all the railroads which were then in operation in all the Slave States, except Maryland. It costs every year five millions more to carry on the domestic slave-trade than it does to fit out and victual all the whale-ships of the United States! ("American Almanac, 1843," p. 178.) Over one fifth of the entire value of the cotton, sugar, rice, and tobacco raised in the fifteen Slave States in 1839, and over one third of the value of articles manufactured in the South, was invested in slaves! Nearly twice as many slaves are carried South and West every year as there are men in all the Slave States engaged in the learned professions!--so terribly prominent is this trade in men and women! Who will venture to conceive, much less express, the deep degradation which must be caused by a trade of such fearful character and magnitude;--degradation not only to the immediate sufferers, but to all those who may be subjected to it?
