Later on, the authorities saw well to recognise what had become a regular practice. Rob Roy’s nephew, Glengyle, who appears to have borne a more respectable character than the uncle, entered into formal contracts to recover stolen cattle, or make good the loss, at the rate of five per cent on the rent of a holding; and in the end he was employed and subsidised by Government as Captain of a Watch, the makeshift police of the border line. More distinguished chiefs were not ashamed to carry on the same business. Scott asserts that one of the last to practise it was Macdonald of Barrisdale--a hero rubbed rather threadbare by Mr. A. Lang--who adorned his claymore with a Virgilian inscription-- Hae tibi erunt artes--pacisque imponere morem, Parcere subjectis, et debellare superbos. Rob Roy’s blackmailing had to be carried on more or less _sub rosa_, but may have been quite as efficient for the protection of those who made terms with him. Such a Highland Robin Hood would have no difficulty in keeping about him a gang of followers like the Dougal cratur and his own sturdy brood. His proceedings in a case of robbery within his jurisdiction are described by Scott from the mouth of an old man in the Lennox, who, scores of years afterwards, told him the tale of this exciting experience. As a herd-lad of fifteen, he had been working with his father on an estate from which some dozen head of cattle were carried off one autumn [Illustration: STIRLING CASTLE] night. Rob Roy was called in, and came with seven or eight men armed as instruments of his function. Having gravely inquired into the symptoms, he soon diagnosed the cause, and set about the remedy with professional promptness, only requiring that two herds should accompany him to identify the cattle and to drive them back when recovered, a duty not to be expected of gentlemen like those who figured in his tail. If Scott’s stories be skimmed nowadays, his notes and introductions are apt to be skipped; so I make bold to borrow freely from one who has so much to lend.
