relation to the royal thanes and the tenantry on demesne lands, as the baron by military service did to the knights and tenantry of his barony. Thus, for instance, the great sheriffdom of Perth was made up, probably, of all the thanages and demesne lands withdrawn from the superintendence of the various earls, of whose ancient Mormaordoms the greater portion is now included in the modern county. In Gowrie there was an earldom and a regality, both remaining under the jurisdiction of the sheriff of Scone, as long as they were both retained in the king’s hands; though, had the earldom been granted away, the authority of the Vicecomes would have been limited to the regality. In Fife alone the Earl continued in the thirteenth century to exercise the prerogatives of a royal Maor; and when Alexander the Second, in accordance with the original gift of David, issued his writs for assigning one-eighth of the profits and fines of Fife and Fortrev to Dunfermlyn, one writ was directed to the sheriff of Fife, the other to Earl Malcolm and his bailies, directing him to make over to the abbey “the eighth, which _ye levied with us_ in the county.”[284] The sheriffdom, however, was introduced by degrees; and in Scottish Argyle, and in Cantyre and Cowal, the duties which devolved in _Moravia_ on the Vicecomes of Inverness were still performed by the Earls of Atholl and Menteith, or the Abbot of Glendochart. David still addressed his mandate in behalf of the abbey of Dunfermlyn to “the earl and proprietary of Caithness and the Orkneys;” and when, in the subsequent reign, Malcolm issued a mandate of the same description to the Earl of Ross, it was similarly addressed to “Earl Malcolm and his thanes.” Four centuries elapsed before there was more than one sheriffdom in ancient _Moravia_--a sure sign of the weakness of the royal authority in early times in the distant north, when the earl, if so inclined, was probably a more efficient delegate to carry out the king’s decrees than the royal Vicecomes of Inverness. Even in Fife the Sheriff is not traceable before the days of William, David always addressing, “the bishop, earl, and proprietary of Fife,” and directing “my judge of that province” to assist at the court of the Abbot of Dunfermlyn; in the same manner as it was incumbent on the sheriff, or his substitute, to be present at a later period on similar occasions.[285] Gradually, however, in all the settled portions of Scotland, the Vicecomes assumed the prerogative of the royal Maor; amongst other duties, settling the rents of the demesne lands, much as his type, the English Sheriff, assessed the _ferms_ levied upon the royal Hundreds or Wapentakes included in his shire. In both countries the sheriffdom occasionally became hereditary, until a statute of Edward the Third fixed a year as the limit of the English Sheriff’s tenure of office. Permanency, and a certain degree of greater dignity, seem still to have attached to the Vicecomes in Scotland,
