Notwithstanding the large emigration which has been going on, the population of the Highlands at the census of 1861 was at least 70,000 greater than it was in the time of Dr Walker.[74] The emigration, especially from the west, does not seem to have been large enough, for periodically, up even to the present day, a rueful call for help to save from famine comes from that quarter. “This very year (1863) the cry of destitution in Skye has been loud as ever, and yet from no part of the Highlands has there been a more extensive emigration. From the very earliest period in the history of emigration down to this date, Skye has been largely drawn upon, and yet the body of the people in Skye were never more wretched than at this moment.”[75] Dr Walker himself states that, in spite of an emigration of about 6000 between the years 1771 and 1794 from the Hebrides and Western Highlands, the population had increased by about 40,000 during the forty years subsequent to 1750.[76] Yet though he knew of the wretched condition of the country from an over-crowded population, practical man as he was, he gives way to the vague and unjustifiable fears expressed above. It is no doubt sad to see the people of a country, and these possessing many high qualities, compelled to leave it in order to get room to breathe; but to tirade against emigration as Dr Walker and others do in the face of such woful facts as are known concerning the condition of the Highlands is mere selfish and wicked sentimentalism. Another fact, stated by the same author, and which might have taught him better doctrines in connection with some of the border parishes, is worth introducing here. The population of seventeen parishes in Dumbartonshire, Perthshire, and Argyllshire, bordering on the low country, decreased in population between 1755 and 1795, from 30,525 to 26,748, _i.e._, by 3,787; these parishes having been during that time to a great extent laid out in cattle and sheep. Now, according to the _Old Statistical Account_ (about 1795), these very parishes were on the whole among the most prosperous in the Highlands, those in which improvements were taking place most rapidly, and in which the condition of the people was growing more and more comfortable. It appears to us clear that the population of the Highlands did require a very considerable thinning; that depopulation to a certain extent was, and in some places still is, a necessary condition to improvement.
