A similar burden under different names emerges in Galloway, when in a charter by David II. to Sir John Heris, knight of the barony of Terreglis, in Dumfriesshire, in which it is declared ‘free of _Sorryn_ and _Fachalos_ unless officers come through it with a robber or with the head of a robber; and if they, the king’s officers, can pass beyond the barony before sunsetting, they shall have nothing for their expenses, and if they cannot pass beyond the barony before sunsetting they shall have hospitality for that night (_hospicium ad hospitandum_),’ etc. _Sorren_ was a tax imposed in Ireland upon the possession of land for the clothing, feeding, and supporting the galloglasses and kernes. It was originally a night’s meal upon land passed through, and _Fachalos_ was probably the Irish _Fechtfele_, which is explained as ‘the first night’s entertainment we receive at each other’s house.’[294] [Sidenote: Expedition and hosting.] The _Feacht_ and _Sluaged_ (_expeditio et exercitus_) consisted of a general obligation, originally upon the members of the tribe, and afterwards upon the possessors and occupiers of what had been tribe territory, to follow their superiors and chiefs as well as the _Ardri_ or sovereign in his expeditions and wars. They are usually termed expedition and hosting, and in Scotland the burden was apportioned upon the davach of land. It is probably this burden that is referred to in the Book of Deer, where we are told that the ‘_Mormaer_ and _Toisech_ immolated all the offerings to God and to devotion, and to Saint Columcille and to Peter the Apostle, free from all the burdens, for a portion of four davachs of what would come on the chief tribe residences generally and on the chief churches.’ These obligations seem to have constituted what is called in charters Scottish service (_servitium Scoticanum_), and were of two kinds, internal and external, the one representing the _Feacht_ or expedition, and the other the _Sluaged_ or hosting. We find them distinguished in a charter by Waldevus de Stratheihan to the church of St. Andrews of the lands of Blaregeroge, which are granted ‘free from all exaction and service, internal and external’ (_sine omne exactione et servitio intrinseco et forinseco_);[295] and their connection with the Davach appears very clearly from three Charters, one by Alexander II. to the abbey of Scone of the lands of Magna et Parva Blar, which contains in the reddendo the clause, ‘rendering the external service only which pertains to five davachs of land, that pertaining to the sixth davach being remitted.’[296] In another by the Earl of Stratherne to Willelmus de Moravia, the lands are granted free of ‘every service except the external Scottish service of our lord the king;’[297] and in a third charter by Alexander the Second to the abbey of Arbroath of the lands of Tarvays, consisting of four davachs and a half davach and quarter davach, they are granted ‘rendering the external service in the army
