In some cases, the farms thus vacated were let to other tacksmen or large tenants, but in most instances, the new system was introduced of letting the land directly to what were formerly the sub-tenants, those who had held the land immediately from the ousted tacksmen. A number of these sub-tenants would take a large farm among them, sub-dividing it as they chose, and each becoming liable for his proportion of the rent. The farms thus let were generally cultivated on the run-rig system already referred to, the pasture being common to all the tenants alike. That certain advantages followed these changes there is no doubt. Every account we have of the Highlands during the earlier part of the 18th century, agrees in the fact that the Highlands were over-peopled and over-stocked, that it was impossible for the land to yield sufficient to support the men and beasts who lived upon it. Hence, this drafting off of a considerable portion of the population gave that which remained breathing-room; fewer people were left to support, and it is to be supposed that the condition of these would be improved. Moreover, they would probably have their farms at a cheaper rent than under the old system, when the demands of both tacksmen and laird had to be satisfied, the former, of course, having let the land at a much higher rate than that at which they held it from their superior. Now, it was possible enough for the laird to get a higher rent than before, and at the same time the people might have their farms at a lower rent than they had previously given to the tacksmen. There would also be fewer oppressive services demanded of these small tenants than under the old system, for now they had only the laird to satisfy, whereas previously they had both him and the tacksman. There would still, of course, be services required by the laird from these tenants, still would part of the rent be paid in kind, still would they be thirled to particular mills, and have to submit to many similar exactions, of the oppressiveness of which, however, it was long before they became conscious; but, on the whole, the condition of those districts from which emigrations took place must to some extent have been the better for the consequent thinning of the population. Still no alteration appears to have taken place in the mode of farming, the nature of tenures, mode of paying rent, houses, clothes, food of the people. In some parts of the Highlands and islands, no alteration whatever appears to have been made on the old system; the tacksmen were allowed to remain undisturbed, and the people lived and held land as formerly. But even in those districts from which emigrations were largely made, little or no improvement seems to have been the consequence, if we may trust the reports of those who saw how things stood with their own eyes. Pennant, Johnson, Buchanan,[58] Newte,[59] the Old Statistical Account, all agree that but little improvement was noticeable over the greater part of the
