Already, any harking back by the landlord upon older and stricter rules--any return, for instance, to the actual services instead of the money payments in lieu of them--produced resentment and insubordination amongst the villein tenants. Murmurs were already heard in the courts, and symptoms appear on the rolls in the year following the Black Death which clearly indicate the presence of smouldering embers very likely soon to burst into flame.[30] The rebellion under Wat Tyler was, in fact, not far ahead. But in this inquiry we are looking backwards into earlier times, in order to learn what English serfdom was when fully in force, rather than in the days when [p032] it was breaking up. In the meantime the practical knowledge gained from the Winslow manor rolls, how a community in serfdom fitted as it were into the open field system as into an outer shell, and still more the knowledge of what the virgate and half-virgate in villenage really were, drawn from actual examples, may prove a useful key in unlocking still further the riddle of earlier serfdom. III. THE HUNDRED ROLLS OF EDWARD I., EMBRACING FIVE MIDLAND COUNTIES. The facts thus learned from the Winslow Manor Rolls throw just that flash of light upon the otherwise dry details of the Hundred Rolls of Edward I. which is needful to make the picture they give in detail of the manors in parts of five midland counties vivid and clear. «Surveys of manors in five counties, A.D. 1279.» English economic history is rich in its materials; and of all the records of the economic condition of England, next to the Domesday Survey, the Hundred Rolls are the most important and remarkable. The second volume, in its 1,000 folio pages, contains _inter alia_ a true and clear description of every manor in a large district, embracing portions of Oxfordshire, Berkshire, Bedfordshire, Huntingdonshire, and Cambridgeshire, in about the year 1279; and as in most cases the name of every tenant is recorded, with the character of his holding and a description of his payments and services, the picture of each manor has almost the detail and accuracy of a photograph. Turning over its pages, the mass of detail may at first appear confused and bewildering, and in one sense it is so, because [p033] it relates to a system which, however simple when fully at work, becomes broken up and entangled whilst in process of disintegration. But the key to it once mastered, the original features of the system may still be recognised. Even the broken pieces fall into their proper places, and the general economic outlines of the several manors stand out sharply and clearly marked. «They are of the Winslow type.»
