the ravages of the cattle which were allowed to roam about the hills, and the depredations of hostile clans. As we have just said, there were no inclosures in the Highlands previous to 1745, nor were there for very many years after that. While the crops were standing in the ground, and liable to be destroyed by the cattle, the latter were kept, for a few weeks in summer and autumn, upon the hills; but after the crops were gathered in, they were allowed to roam unheeded through the whole of a district or parish, thus affording facilities for the cattle-raids that formed so important an item in the means of obtaining a livelihood among the ancient Highlanders. As a rule, the only crops attempted to be raised were oats and barley, and sometimes a little flax; green crops were almost totally unknown or despised, till many years after 1745; even potatoes do not seem to have been at all common till after 1750, although latterly they became the staple food of the Highlanders. Rotation of crops, or indeed any approach to scientific agriculture, was totally unknown. The ground was divided into infield and outfield. The infield was constantly cropped, either with oats or bear; one ridge being oats, the other bear alternately. There was no other crop except a ridge of flax where the ground was thought proper for it. The outfield was ploughed three years for oats, and then pastured for six years with horses, black cattle, and sheep. In order to dung it, folds of sod were made for the cattle, and what were called flakes or rails of wood, removable at pleasure, for folding the sheep. A farmer who rented 60, 80, or 100 acres, was sometimes under the necessity of buying meal for his family in the summer season.[12] [Illustration: 1.
