REASONS FOR IMMOBILITY 305 the soil?" Many things, no doubt; but one was of overwhelming, importance: a sense of fair play and an ability to compromise. We have seen that changing conditions were forcing men to view things in a new light: little by little even the most grasping lords were relinquishing some of their immemorial rights. Here and there up and down the countryside, week-works were dying out as the lord and his serfs found their interests marching side by side in exchanging a service rent for one of money. Again, we have seen the constant challenge of the towns: privileged, compara- tively safe, seemingly luxurious—they were throughout these centuries a magnet which attracted a percentage of those peasants living around them—how large a percentage we cannot tell. But there they were; and, as we have seen, the lord with average foresight knew he must deal with them. Once let the opinion gain ground that the manorial conditions were unfairly exacting, and flight became a subject of discussion within the village ale-house, and in the moments of rest in the fields and at the plough. The Abbot of Burton may have won the applause of lawyers when he told his serfs that they had nothing of their own save their bellies (nihil praefer ventrem), but he was a foolish fellow nevertheless.1 Again, the story of Bury St Edmunds shows clearly enough what difficulties landlords created for themselves by a resolute refusal to see how the times were changing.2 In general, however, lord and peasant found it mutually convenient to compromise—the well-known phrase of the customals "and he shall serve ad voluntatem domini et secundum consuetudinem manerii" shows how custom had taken its place in manorial life, and that "the will of the lord" had been softened by the passage of time, so that it had now to be interpreted by the custom of the manor.3 The majority of peasants were kept on the manor by a reluctance to leave home, and a general belief that their lot was not unduly hard but approximated to that of their neigh- bours.4 1 Wm.

Herts, iv, 186, where it says that flight was rare in the thirteenth century, for as commutation increased there was less necessity to bind tenants to the soil.
