44 THE MANOR becomes clear that immediately in front of us is a large arable field. Unlike a modern farm it seems to have no boundaries—at least there are no hedges, dividing one part from another, and nothing to prevent us from walking across its length and out into the grazing lands beyond. A closer examination, however, will show us that this great field is, nevertheless, divided up into a number of compartments or large divisions. These go by many names—furlongs, shots, dells—and each of these compartments is again subdivided into a certain number of strips (or selions), each divided from the other by raised balks of unploughed land. The strips run parallel, one to the other, the whole length of the furlong or shot, and are generally found to contain half an acre or one acre of land. At right angles to them run the "headlands" —unploughed portions which give access to the strips in that furlong, and also to the other parts of the great field. As we shall see, the peasant did not hold all his strips in one convenient block, but had them allocated to him in various parts of this, and of the other great fields of the manor. This was a principle of great antiquity: it is of the essence of these peasant holdings that they shall each be of comparatively small size and scattered over the whole of the common fields. The very term, "the common fields*', reminds us that much medieval farming was a co-operative affair. But we are by no means as dear as we should like to be as to how far this was so in actual practice. The generally accepted theory envisages the peasants carrying out all the principal occupations of agriculture in common. Reasons will be given later for thinking that there was more individual enterprise than has been imagined, but we may begin by admitting that the fields were cultivated according to a plan which had the sanction of time immemorial, or of general village consent, and that everyone had to fall in with this. Indi- vidual cultivation of any particular crop was almost impossible and had to be reserved for the little " closes " round the home, or for the "assart" land newly brought into cultivation by the peasant, and which lay outside the "common fields" and was generally on the outskirts of the manor. In the common fields, however, when oats were sowed by one they were, perforce, sown by all. The most considerable operation, of course, was ploughing, and how far this was a communal affair it is hard to teU. Clearly,
