the degradation of the free farmers; and that they prove the richer classes of the Roman Empire to have become aware of the increased value which landed property obtains when the cultivator had an interest in the produce of the land. We know that their servitude was predial; that it wanted many of the characteristics of absolute slavery, and that they acquitted their service to the landlord in rendering to him a fixed portion of the annual crop. We know further that they survived all the mutations of society in the ancient and modern worlds. Though included in the lower courses of the feudal structure, they continued in many countries to render to the landlord precisely the same dues which they had paid to the Roman _dominus_, and from a particular class among them, the _coloni medietarii_ who reserved half the produce for the owner, are descended the _metayer_ tenantry, who still conduct the cultivation of the soil in almost all the South of Europe. On the other hand, the Emphyteusis, if we may so interpret the allusions to it in the _Corpus Juris_, became a favourite and beneficial modification of property; and it may be conjectured that wherever free farmers existed, it was this tenure which regulated their interest in the land. The Praetor, as has been said, treated the Emphyteuta as a true proprietor. When ejected, he was allowed to reinstate himself by a Real Action, the distinctive badge of proprietory right, and he was protected from disturbance by the author of his lease so long as the _canon_, or quit-rent, was punctually paid. But at the same time it must not be supposed that the ownership of the author of the lease was either extinct or dormant. It was kept alive by a power of re-entry on nonpayment of the rent, a right of pre-emption in case of sale, and a certain control over the mode of cultivation. We have, therefore, in the Emphyteusis a striking example of the double ownership which characterised feudal property, and one, moreover, which is much simpler and much more easily imitated than the juxtaposition of legal and equitable rights. The history of the Roman tenure does not end, however, at this point. We have clear evidence that between the great fortresses which, disposed along the line of the Rhine and Danube, long secured the frontier of the Empire against its barbarian neighbours, there extended a succession of strips of land, the _agri limitrophi_, which were occupied by veteran soldiers of the Roman army on the terms of an Emphyteusis. There was a double ownership. The Roman State was landlord of the soil, but the soldiers cultivated it without disturbance so long as they held themselves ready to be called out for military service whenever the state of the border should require it. In fact, a sort of garrison-duty, under a system closely resembling that of the military colonies on the Austro-Turkish border, had taken the place of the quit-rent which was the service of the ordinary Emphyteuta. It seems
