The Highlanders in particular are masters of this difficult trade of driving, which seems to suit them as well as the trade of war. It affords exercise for all their habits of patient endurance and active exertion. They are required to know perfectly the drove-roads, which lie over the wildest tracts of the country, and to avoid as much as possible the highways, which distress the feet of the bullocks, and the turnpikes, which annoy the spirit of the drover; whereas on the broad green or grey track, which leads across the pathless moor, the herd not only move at ease and without taxation, but, if they mind their business, may pick up a mouthful of food by the way. At night, the drovers usually sleep along with their cattle, let the weather be what it will; and many of these hardy men do not once rest under a roof during a journey on foot from Lochaber to Lincolnshire. They are paid very highly, for the trust reposed is of the last importance, as it depends on their prudence, vigilance, and honesty whether the cattle reach the final market in good order, and afford a profit to the grazier. But, as they maintain themselves at their own expense, they are especially economical in that particular. At the period we speak of, a Highland drover was victualled for his long and toilsome journey with a few handfuls of oatmeal and two or three onions, renewed from time to time, and a ram's horn filled with whisky, which he used regularly, but sparingly, every night and morning. His dirk, or skene-dhu (i.e. black knife), so worn as to be concealed beneath the arm, or by the folds of the plaid, was his only weapon, excepting the cudgel with which he directed the movements of the cattle. A Highlander was never so happy as on these occasions. There was a variety in the whole journey which exercised the Celt's natural curiosity and love of motion; there were the constant change of place and scene, the petty adventures incidental to the traffic, and the intercourse with the various farmers, graziers, and traders, intermingled with occasional merry-makings, not the less acceptable to Donald that they were void of expense; and there was the consciousness of superior skill: for the Highlander, a child amongst flocks, is a prince amongst herds, and his natural habits induce him to disdain the shepherd's slothful life, so that he feels himself nowhere more at home than when following a gallant drove of his country cattle in the character of their guardian.
