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 Métayer .
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 lord, 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 métayer to make the land produce as much as could be brought out of it by means of the stock furnished by the proprietor; but it could never be his interest to mix any part of his own with it. In France, where five parts out of six of the whole kingdom are said to be still occupied by this species of cultivators, the proprietors complain that their métayers take every opportunity of employing the masters cattle rather in carriage than in cultivation; because in the one case they get the whole profits to themselves, in the other they share them with their landlord. This species of tenants still subsists in some parts of Scotland. They are called steel-bow tenants. Those ancient English tenants, who are said by Chief Baron Gilbert and Doctor Blackstone to have been rather bailiffs of the landlord than farmers properly so called, were probably of the same kind.
