should be as great as possible, in order that their own proportion may be so. A slave, on the contrary, who can acquire nothing but his maintenance, consults his own ease, by making the land produce as little as possible over and above that maintenance. It is probable that it was partly upon account of this advantage, and partly upon account of the encroachments which the sovereigns, always jealous of the great lords, gradually encouraged their villains to make upon their authority, and which seem, at least, to have been such as rendered this species of servitude altogether inconvenient, that tenure in villanage gradually wore out through the greater part of Europe. The time and manner, however, in which so important a revolution was brought about, is one of the most obscure points in modern history. The church of Rome claims great merit in it; and it is certain, that so early as the twelfth century, Alexander III. published a bull for the general emancipation of slaves. It seems, however, to have been rather a pious exhortation, than a law to which exact obedience was required from the faithful. Slavery continued to take place almost universally for several centuries afterwards, till it was gradually abolished by the joint operation of the two interests above mentioned; that of the proprietor on the one hand, and that of the sovereign on the other. A villain, enfranchised, and at the same time allowed to continue in possession of the land, having no stock of his own, could cultivate it only by means of what the landlord advanced to him, and must therefore have been what the French call a metayer.
It could never, however, be the interest even of this last species of cultivators, to lay out, in the further improvement of the land, any part of the little stock which they might save from their own share of the produce; because the landlord, who laid out nothing, was to get one half of whatever it produced. The tithe, which is but a tenth of the produce, is found to be a very great hindrance to improvement. A tax, therefore, which amounted to one half, must have been an effectual bar to it. It might be the interest of a metayer to make the land produce as much as could be brought out of it by means of the stock furnished by the
