the first field is said to contain 174 acres, the second 63, the third 109, the fourth 69 acres. Two-thirds of the whole are subjected to the usual modes of cultivation under a three-course system, and one-third remains for pasture. But out of this last third, 40 acres of the first field (of 174 acres) get inclosed and used for crop in one year, and 20 acres of the second in another.(9*) In this way the ordinary three-course alternation becomes somewhat more complicated, and it will be hardly too bold a guess to suppose that such extra-cultivation implied some manuring of such patches as were deprived of their usual rest once in three years. In contradiction to the customary arrangement which did not require any special manuring except that which was incident to the use of arable as pasture for the cattle after the harvest, we find plots set apart for more intense cultivation,(10*) and it is to be noticed that the reckoning in connexion with them does not start from the division according to three parts, but supposes a separate classification in two sections.
Another fact worth noticing in the Gloucester instance is the irregular distribution of acres in the 'fields,' and the division of the entire arable into four unequal parts. The husbandry is conducted on the three-course system, and still four fields are mentioned, and there is no simple relation between the number of acres which they respectively contain (174, 63, 109, 69). It seems obvious that the expression 'field' (campus) is used here not in the ordinary sense suggested by such records as spring-field, winter-field, and the like, but in reference to the topography of the district. The whole territory under cultivation was divided into a number of squares or furlongs which lay round the village in four large groups. The alternation of crops distributed the same area into three according to a mode not described by the Survey, and it looks proVable at first glance that each of the 'fields' (campi) contained elements of all three courses. The supposition becomes a certainty, if we reflect that it gives the only possible explanation of the way in which the twofold alternation of the 'inhoc' is made to fit with the threefold rotation of crops: every year some of the land in each campus had to remain in fallow, and could be inclosed or taken under 'inhoc.' Had the campus as a whole been reserved for one of the three courses, there would have been room for the 'inhoc'
only every three years.
I have gone into some details in connexion with this instance because it presents a deviation from ordinary rules, and even a deviation from the usual phraseology, and it is probable that the exceptional use of words depended on the exceptional process of farming. A new species of arable -- the manured plot under 'inhoc' -- came into use, and naturally disturbed the plain arrangement of the old-fashioned three courses; the lands had to be grouped anew into four sections which went under the accustomed designation of 'fields,' although they did not fit in with the 'three fields' of the old system. In most cases, however, our records use the word 'field' (campus) in that very sense of land under one of the 'courses,' which is out of the question in the case taken from the Gloucester Cartulary. The common use is especially clear when the documents want to describe the holding of a person, and mention the number of acres in each 'field.' The Abbot of Malmesbury, e.g., enfeoffs one Robert with a virgate formerly held 'in the fields' by A., twenty-one acres in one field and twenty-one in another.(11*) The charter does not contain any description of campi in the territorial sense, and it is evident that the expression 'in the fields' is meant to indicate a customary and well-known husbandry arrangement. The same meaning must be put on sentences like the following: -- R.A. holds a virgate consisting of forty-two acres in both fields.(12*) The question may be raised whether we have to look for 'both fields' in the winter and springfield of the three courses rotation, or in the arable and fallow of the two courses. In the first of these eventualities, the third reserved for pasture and rest would be left out of the reckoning; it would be treated as an appurtenance of the land that was in cultivation. Cases in which the portions in the several fields are unequal seem to point to the second sense.(13*) It was impossible to divide the whole territory under cultivation like a piece of paper: conformation of the soil had, of course, much to do with the shape of the furlongs and their distribution, and the courses of the husbandry could not impress themselves on it without some inequalities and stray remnants. It may happen for this reason that a man holds sixteen acres in one field and fourteen in the other. There is almost always, however, a certain correspondence between the number of acres in each field;instances of very great disparity are rare, and suppose some local and special reasons which we cannot trace. Such disparities seem to point, however, to a rotation according to two courses, because the fallow of the three courses could have been left out of the reckoning only if all the parts in the fields were equal.(14*) I think that a careful inspection of the surveys from this point of view may lead to the conclusion that the two courses rotation was very extensively spread in England in the thirteenth century.
