These three types--Mrs. Stowe's Uncle Tom, and the Shelbys, his master and mistress--were the outgrowth of natural and historic conditions peculiar to Kentucky. "Perhaps," wrote Mrs. Stowe in her novel, "the mildest form of the system of slavery is to be seen in the State of Kentucky. The general prevalence of agricultural pursuits of a quiet and gradual nature, not requiring those periodic seasons of hurry and pressure that are called for in the business of more southern districts, makes the task of the negro a more healthful and reasonable one; while the master, content with a more gradual style of acquisition, had not those temptations to hard-heartedness which always overcome frail human nature, when the prospect of sudden and rapid gain is weighed in the balance with no heavier counterpoise than the interests of the helpless and unprotected." These words contain many truths. For it must not be forgotten, first of all, that the condition of the slave in Kentucky was measurably determined by certain physical laws which lay beyond the control of the most inhuman master. Consider the nature of the country--elevated, rolling, without miasmatic districts or fatal swamps; the soil in the main slave-holding portions of the State easily tilled, abundantly yielding; the climate temperate and invigorating. Consider the system of agriculture--not that of vast plantations, but of small farms, part of which regularly consisted of woodland and meadow that required little attention. Consider the further limitations to this system imposed by the range of the great Kentucky staples--it being in the nature of corn, wheat, hemp, and tobacco, not to yield profits sufficient to justify the employment of an immense predial force, nor to require seasons of forced and exhausting labor. It is evident that under such conditions slavery was not stamped with those sadder features which it wore beneath a devastating sun, amid unhealthy or sterile regions of country, and through the herding together of hundreds of slaves who had the outward but not the inward discipline of an army. True, one recalls here the often quoted words of Jefferson on the raising of tobacco--words nearly as often misapplied as quoted; for he was considering the condition of slaves who were unmercifully worked on exhausted lands by a certain proletarian type of master, who did not feed and clothe them. Only under such circumstances could the culture of this plant be described as "productive of infinite wretchedness," and those engaged in it as "in a continual state of exertion beyond the powers of nature to support." It was by reason of these physical facts that slavery in Kentucky assumed the phase which is to be distinguished as domestic; and it was this mode that had prevailed at the North and made emancipation easy.
