A second group of free tenements consists of plots which did not belong either to the demesne or to the regular holdings in the fields, but lay by the side of these holdings and were parcelled out in varying quantity and under various conditions. We may begin by noticing the growth of leases. There is no doubt that the lease-system was growing in the thirteenth century, and that it is not adequately reflected in our documents. An indirect proof of this is given by the fact, that legal practice was labouring to discover means of protection for possession based on temporary agreement. The writ 'Quare ejecit infra terminum' invented by William Raleigh between 1236 and 1240 protected the possession of the 'tenant for term of years' who formerly had been regarded as having no more than a personal right enforceable by an action of covenant[724]. Manorial extents are sparing in their notices of leases because their object is to picture the distribution of ownership, and temporary agreements are beyond their range. But it is not uncommon to find a man holding a small piece of land for his life at a substantial rent. In this case his tenure is reckoned freehold, but still he holds under what we should now call a lease for life; the rent is a substantial return for the land that he has hired. That English law should regard these tenants under leases for life as freeholders, should, that is, throw them into one great class with tenants who have heritable rights, who do but military service or nominal service, who are in fact if not in name the owners of the land, is very remarkable; hirers are mingled with owners, because according to the great generalisation of English feudalism every owner is after all but a hirer. Still we can mark off for economic purposes a class of tenants whom we may call 'life-leaseholders,' and we can see also a smaller class of leaseholders who hold for terms of years[725]. They often seem to owe their existence to the action of the manorial bailiffs or the farmers to whom the demesne has been let. We are told that such and such a person has 'entered' the tenement by the leave of such and such a farmer or bailiff, or that the tenement does not belong to the occupier by hereditary right, but by the bailiff's precept[726]. Remarks of that kind seem to mean that these rent-paying plots, liberated from servile duties, were especially liable to the interference of manorial officers. Limits of time are rarely mentioned, and leases for life seem to be the general rule[727]. The tenure is only in the course of formation, and by no means clearly defined. One does not even see, for instance, how the question of implements and stock was settled--whether they were provided by the landlord or by the tenant. [Forlands.]
