But it is urged that it is the interest of planters to treat their slaves well. This argument no doubt has some force; and it is the poor negro's only security. But it is likewise the interest of men to treat their cattle kindly; yet we see that passion and short-sighted avarice do overcome the strongest motives of interest. Cattle are beat unmercifully, sometimes unto death; they are ruined by being over-worked; weakened by want of sufficient food; and so forth. Besides, it is sometimes directly _for_ the interest of the planter to work his slaves beyond their strength. When there is a sudden rise in the prices of sugar, a certain amount of labor in a given time is of more consequence to the owner of a plantation than the price of several slaves; he can well _afford_ to waste a few lives. This is no idle hypothesis--such calculations are gravely and openly made by planters. Hence, it is the slave's prayer that sugars may be cheap. When the negro is old, or feeble from incurable disease, is it his master's _interest_ to feed him well, and clothe him comfortably? Certainly not: it then becomes desirable to get rid of the human brute as soon as convenient. It is a common remark, that it is not quite safe, in most cases, for even parents to be entirely dependant on the generosity of their children; and if human nature be such, what has the slave to expect, when he becomes a mere bill of expense? It is a common retort to say that New-Englanders who go to the South, soon learn to patronize the system they have considered so abominable, and often become proverbial for their severity. I have not the least doubt of the fact; for slavery contaminates all that comes within its influence. It would be very absurd to imagine that the inhabitants of one State are worse than the inhabitants of another, unless some peculiar circumstances, of universal influence, tend to make them so. Human nature is every where the same; but developed differently, by different incitements and temptations. It is the business of wise legislation to discover what influences are most productive of good, and the least conducive to evil. If we were educated at the South, we should no doubt vindicate slavery, and inherit as a birthright all the evils it engrafts upon the character. If they lived on our rocky soil, and under our inclement skies, their shrewdness would sometimes border upon knavery, and their frugality sometimes degenerate into parsimony. We both have our virtues and our faults, induced by the influences under which we live, and, of course, totally different in their character. _Our_ defects are bad enough; but they cannot, like slavery, affect the destiny and rights of millions.
