The amount of enclosure in the fifteenth, sixteenth, and the first half of the seventeenth centuries was, according to the latest research, much, and perhaps very naturally, exaggerated by contemporaries. Between 1455-1607 the enclosures in twenty-four counties are said to have amounted to some 500,000 acres, or 2.76 of their total area,[277] but the evidence for this is by no means conclusive. However, there seems no reason to doubt that the enclosure of this period was but a faint beginning of that great outburst of it that marked the agrarian revolution of the middle of the eighteenth century, and that it was mainly confined to the Midland counties, Mr. Johnson, in his recent Ford Lectures, has stated that the enclosure of the sixteenth and seventeenth centuries was not accompanied by very much direct eviction of freeholders or bona fide copyholders of inheritance; yet the small holder suffered in many ways, e.g. by the lord disproving the hereditary character of the copyhold, or by changing copyholds of inheritance into copyholds for lives or leases for lives or years. He and his successors could then refuse to renew at the termination of lives or years except on payment of a practically prohibitory fine. In short, though there was not much violation of legal right there was much injustice, and enclosure, though its effects were exaggerated at this period, certainly tended to displace the small landholder. It does not appear, however, that the moderate-sized proprietors were seriously affected. Many of the larger freeholders and copyholders on manors enclosed on their own account, and perhaps increased at the expense of the very large and the very small. Indeed, the decrease of small landowners was chiefly due to political and social causes. The old self-sufficing, agricultural economy of England, which we have seen beginning to break up in the fourteenth century, was becoming thoroughly disintegrated. The capitalist class was increasing; the successful merchant and lawyer were acquiring land and becoming squires; there was an intense land hunger. Simon Degge, wilting of Staffordshire in 1669, says that in the previous sixty years half the lands had changed owners, not so much as of old they were wont to do, by marriage, but by purchase; and he notices how many lawyers and tradesmen have supplanted the gentry.[278]
