The policy of that great family had latterly been rather to attach this wild tribe by kindness than to follow the mode of violence which had been hitherto ineffectually resorted to.

Leases at a low rent were granted to many of the MacGregors, who had heretofore held possessions in the Duke's Highland property merely by occupancy; and Glengyle (or Black-knee), who continued to act as collector of black-mail, managed his police, as a commander of the Highland watch arrayed at the charge of Government.

He is said to have strictly abstained from the open and lawless depredations which his kinsman had practised.
It was probably after this state of temporary quiet had been obtained, that Rob Roy began to think of the concerns of his future state.

He had been bred, and long professed himself, a Protestant; but in his later years he embraced the Roman Catholic faith,--perhaps on Mrs.Cole's principle, that it was a comfortable religion for one of his calling.

He is said to have alleged as the cause of his conversion, a desire to gratify the noble family of Perth, who were then strict Catholics.
Having, as he observed, assumed the name of the Duke of Argyle, his first protector, he could pay no compliment worth the Earl of Perth's acceptance save complying with his mode of religion.
