these three classes and their officials (bailiffs, seneschals, reeves, &c.) were the free tenants, who did no regular work for the manor, but could not leave or part with their land. Their services were requisitioned at certain periods like harvest-time, when there came a demand for more than the ordinary number of hands. This sort of labour was known as boon-work. It is clear at once that, theoretically at least, there was no room in such a community for the modern landless labourer. Where all the workers were paid by their tenancy of land, where, in other words, fixity and stability of possession were the very basis of social life, the fluidity of labour was impossible. Men could not wander from place to place offering to employers the hire of their toil. Yet we feel sure that, in actual fact, wherever the population increased, there must have grown up in the process of time a number of persons who could find neither work nor maintenance on their father's property. Younger sons, or more remote descendants, must gradually have found that there was no scope for them, unless, like an artisan class, they worked for wages. Exactly at what date began the rise of this agricultural and industrial class of fee labourers we cannot very clearly tell. But in England--and probably the same holds good elsewhere--between 1200 and 1350 there are traces of its great development. There is evidence, which each year becomes more ample and more definite, that during that period there was an increasingly large number of people pressing on the means of subsistence. Though the land itself might be capable of supporting a far greater number of inhabitants, the part under cultivation could only just have been enough to keep the actually existing population from the margin of destitution. The statutes in English law which protest against a wholesale occupation of the common-land by individuals were not directed merely against the practices of a landlord class, for the makers of the law were themselves landlords. It is far more likely that this invasion of village rights was due to the action of these "landless men," who could not otherwise be accommodated. The superfluous population was endeavouring to find for itself local maintenance.
