Note 30 — Chapter I

‘By retiring to his own castle, a mutinous baron could defy the power of his sovereign, it being almost impracticable to lead an army through a barren country, to places of difficult access to a single man.’ History of Scotland, book i. p. 59, in Robertson's Works, edit. London, 1831. Notwithstanding the immense materials which have been brought to light since the time of Robertson, his History of Scotland is still valuable; because he possessed a grasp of mind which enabled him to embrace general views, that escape ordinary compilers, however industrious they may be.
