"How different is it with slave labor! The slave toils for another, and not for himself. Whether he does little or much, whether his work is well or ill performed, he has a subsistence, nothing less, nothing more; and why should he toil beyond necessity? He cannot accumulate any property for the decline of his years, or to leave to his children when he is departed. Nay, he cannot toil to better the present condition of his children. They belong to another, and not to him. He cannot supply his hut with comforts, or embellish it with the adornments of taste. He does not read. He does not journey for pleasure. Inducements to exertion, he has none. That he may adapt himself to his condition, and enjoy the present hour, he deadens those aspirations that must always be baffled in his case, and sinks down into ease and sensuality. His mind is unlighted and untutored; dark with ignorance. Among those who value him most, he is proverbially indolent, thievish, and neglectful of his master's interests. It is common for even the advocates of slavery to declare that one freeman is worth half a dozen slaves. With every cord to exertion thus sundered, the mind benighted, the man nearly lost in the animal, it requires no deep philosophy to see why labor cannot be near as productive as it would be were these conditions all reversed. Though ever so well directed by the superior skill, and urged forward by the strong arm of the master, slave labor is necessarily a blight to the soil--sterility follows in its steps, and not afar off.
