value and in numbers when well treated. The law of self-interest secures kind and humane treatment to Southern slaves. All the legislative ingenuity in the world will never enact so efficient a law in behalf of free laborers. During the decline of the Roman Empire, slavery became colonial or prædial. The slaves occupied the place of tenants or serfs, were "adscripti soli," and could only be sold with the farm. Many antiquarians consider the colonial slavery of the Romans as the true origin of the feudal system. This kind of slavery was universal in Europe till a few centuries since, and now prevails to a great extent. The serfs of Russia, Poland, Turkey, and Hungary, are happier and better provided for than the free laborers of Western Europe. They have homes, and lands to cultivate. They work but little, because their wants are few and simple. They are not over-worked and under-fed, as are the free laborers of Western Europe. Hence, they never rise in riots and insurrections, burn houses, commit strikes,--nor do they emigrate. This form of slavery, however, makes the master an idle absentee, depriving the slaves of his guardianship, his government, and his protection. By throwing large masses of the ignorant into exclusive association with each other, it promotes and increases ignorance, negligence and idleness. Men will not improve their condition who have no examples to emulate and no teachers to instruct. Were their farms conducted as ours of the South, the wealthy would have ample employment, and the slaves or serfs find in their masters examples, governors, teachers and protectors. The right to sell one's children, or one's self, into slavery has been very common, and is now practiced in China. The ancient Germans used to even stake their liberty at games of hazard. This would never have been done, nor would the laws have permitted it, if the situation of the slave had been greatly inferior to that of the free. But how shall we class wives, children, wards, apprentices, prisoners, soldiers and sailors? They are not free, because their personal liberty is controlled by the will of a superior; not by mere law. They are liable to confinement and punishment by their superiors, whose will stands in place of law as to them. They have no right of locomotion like that enjoyed by the free. They have no liberty secured by law;--they are not free. Are they, therefore, slaves?
