"One of our earliest expeditions was to visit the wild scenery of the mountainous tract above Moffat, including the cascade of the 'Gray Mare's Tail,' and the dark tarn called 'Loch Skene.' In our ascent to the lake, we got completely bewildered in the thick fog which generally envelopes the rugged features of that lonely region; and, as we were groping through the maze of bogs, the ground gave way, and down went horse and horsemen pell-mell into a slough of peaty mud and black water, out of which, entangled as we were with our plaids and floundering nags, it was no easy matter to get extricated. Indeed, unless we had prudently left our gallant steeds at a farm-house below, and borrowed hill ponies for the occasion, the result might have been worse than laughable. As it was, we rose like the spirits of the bog, covered _cap-à-pie_ with slime, to free themselves from which, our wily ponies took to rolling about on the heather, and we had nothing for it but following their example. At length, as we approached the gloomy loch, a huge eagle heaved himself from the margin and rose right over us, screaming his scorn of the intruders; and altogether it would be impossible to picture any thing more desolately savage than the scene which opened, as if raised by enchantment on purpose to gratify the poet's eye; thick folds of fog rolling incessantly over the face of the inky waters, but rent asunder now in one direction, and then in another--so as to afford us a glimpse of some projecting rock or naked point of land, or island, bearing a few scraggy stumps of pine--and then closing again in universal darkness upon the cheerless waste. Much of the scenery of Old Mortality was drawn from that day's ride. "It was also in the course of this excursion that we encountered that amusing personage introduced into Guy Mannering as 'Tod Gabbie,' though the appellation by which he was known in the neighborhood was 'Tod Willie.' He was one of these itinerants who gain a subsistence among the moorland farmers by relieving them of foxes, pole-cats, and the like depredators--a half-witted, stuttering, and most original creature." The subjoined extract will serve to show the great humility with which Scott bore his literary honors, at a time when he was beleaguered by the importunities of fashionable admirers. His bearing, says Mr. Lockhart, when first exposed to such influences, was exactly what it was to the end. The Border Minstrel is writing from London, whither he had proceeded upon business connected with an important prospective situation as Clerk of the Edinburgh Sessions, a lucrative and desirable station:
