There was some originality in the man's habits of thinking and expressing himself, his turn for legendary lore strangely contrasting with a portion of the knowing shrewdness belonging to his actual occupation, which made his conversation amuse the way well enough.
Add to this, Donald knew all his peculiar duties in the country which he traversed so frequently.

He could tell, to a day, when they would "be killing" lamb at Tyndrum or Glenuilt; so that the stranger would have some chance of being fed like a Christian; and knew to a mile the last village where it was possible to procure a wheaten loaf for the guidance of those who were little familiar with the Land of Cakes.

He was acquainted with the road every mile, and could tell to an inch which side of a Highland bridge was passable, which decidedly dangerous.

[This is, or was at least, a necessary accomplishment.

In one of the most beautiful districts of the Highlands was, not many years since, a bridge bearing this startling caution, "Keep to the right side, the left being dangerous."] In short, Donald MacLeish was not only our faithful attendant and steady servant, but our humble and obliging friend; and though I have known the half-classical cicerone of Italy, the talkative French valet-de-place, and even the muleteer of Spain, who piques himself on being a maize-eater, and whose honour is not to be questioned without danger, I do not think I have ever had so sensible and intelligent a guide.
Our motions were of course under Donald's direction; and it frequently happened, when the weather was serene, that we preferred halting to rest his horses even where there was no established stage, and taking our refreshment under a crag, from which leaped a waterfall, or beside the verge of a fountain, enamelled with verdant turf and wild-flowers.
Donald had an eye for such spots, and though he had, I dare say, never read Gil Blas or Don Quixote, yet he chose such halting-places as Le Sage or Cervantes would have described.
