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 impossible to doubt that this was the precedent copied by the barbarian monarchs who founded feudalism. It had been within their view for some hundred years, and many of the veterans who guarded the border were, it is to be remembered, themselves of barbarian extraction, who probably spoke the Germanic tongues. Not only does the proximity of so easily followed a model explain whence the Frankish and Lombard Sovereigns got the idea of securing the military service of their followers
