But still the man of science cannot complain of inactivity or want of practice. If he does not find patients at his door, he seeks them through a wide circle. Like the ghostly lover of Burger's Leonora, he mounts at midnight and traverses in darkness, paths which, to those less accustomed to them, seem formidable in daylight, through straits where the slightest aberration would plunge him into a morass, or throw him over a precipice, on to cabins which his horse might ride over without knowing they lay in his way, unless he happened to fall through the roofs. When he arrives at such a stately termination of his journey, where his services are required, either to bring a wretch into the world, or prevent one from leaving it, the scene of misery is often such, that, far from touching the hard-saved shillings which are gratefully offered to him, he bestows his medicines as well as his attendance--for charity. I have heard the celebrated traveller Mungo Park, who had experienced both courses of life, rather give the preference to travelling as a discoverer in Africa, than to wandering by night and day the wilds of his native land in the capacity of a country medical practitioner. He mentioned having once upon a time rode forty miles, sat up all night, and successfully assisted a woman under influence of the primitive curse, for which his sole remuneration was a roasted potato and a draught of buttermilk. But his was not the heart which grudged the labour that relieved human misery. In short, there is no creature in Scotland that works harder and is more poorly requited than the country doctor, unless perhaps it may be his horse. Yet the horse is, and indeed must be, hardy, active, and indefatigable, in spite of a rough coat and indifferent condition; and so you will often find in his master, under an unpromising and blunt exterior, professional skill and enthusiasm, intelligence, humanity, courage, and science.
