It would appear from all the evidence at hand that while Kentucky furnished many slaves for the southern market there was no general internal slave trade, as a commercial enterprise. There were in Louisville, however, a few heartless business men who took advantage of the decreasing value of slave labor in Kentucky and the rising prices of slaves in the far South. In this respect, Kentucky became a field of supply for the slave markets of the lower South.

Unfortunately there are no statistics available by which the number of slaves sent south can be computed. The most comprehensive anti-slavery publication on the internal slave trade was unable to decide with certainty what proportion of slaves for the southern market was furnished by each of the so-called breeding States. The author of Slavery and Internal Slave Trade in the United States estimated that 80,000 slaves were annually exported from seven States to the South. He gave no figures that were not his own estimates. He ranked the seven States, however, in the order of the number of slaves which he thought they furnished as follows: Virginia, Maryland, North Carolina, Kentucky, Tennessee, Missouri and Delaware.[274]

Martin estimates that Kentucky sent on the average about 5,000 slaves to the southern market.[275] Again this must be considered purely conjectural. It is reasonable to suppose that during the last two decades of the slavery era there were few slaves imported into Kentucky that were intended for the purely Kentucky market. What Negroes came into Kentucky were for the most part on their way to the more profitable southern trade. The average death rate among the slaves during this period was 1.9 per one hundred and the birth rate was 3.2, or an excess of births over deaths of 1.1 per hundred. This would make the annual natural increase among the slave population about 2,000 per year. Comparing this with the growth of the slave group from 1840 to 1850 we find that the increase of slaves was much more. But it was during the next decade that the slave trade reached its height and here we find that the slave population increased 14,502, whereas the natural increase during that period should have been 23,190. Hence the slaves failed to reach even their natural increase by a deficiency of 8,688. Taken literally that would mean that during the ten-year period that number of slaves were exported from Kentucky. But it is reasonable to suppose that many more than that were sent to the South. With the exception of the last decade, however, the slave population of Kentucky increased faster than the mere natural increase of the Negroes. The law would not permit of any importation of slaves intended for Kentucky, so the export of purely Kentucky slaves appears never to have been prominent except during the decade from 1850 to 1860.

The selling price of slaves naturally presents itself at this point. In Kentucky these records are very few because the tax books in practically all the counties of the State have been destroyed. We have no accurate statements extant before about the year 1855. The prices which we have obtained are quotations from the auction of slaves of estates to settle the interests of the heirs. On January court day, in 1855, there were sold in the settlement of estates in Bourbon, Fayette, Clark and Franklin Counties Negro men who brought $1,260, $1,175, $1,070, $1,378, $1,295, $1,015 and $1,505.[276] The county commissioner of Harrison auctioned the slaves of the deceased George Kirkpatrick with the following prices received:

The county commissioner at Henderson received the following prices for slaves in the settlement of several estates on January 28, 1858:[278]

This sale is most significant for the cases of "Delphy," 80 years old, and "Cupid," 85 years of age. It is difficult to account for such a sale in any discussion of the slave trade, but it does show the humanitarian side of Kentucky slavery. Negroes at such an age had no economic value even if they were given away, because the expense of their maintenance was more than the value of any possible labor they could perform.

At Georgetown in December of the same year we have this record:[279]
