From the middle of last century to the beginning of this, emigration went on except when war made it impossible. The dangerous qualities of the highlanders made them very valuable in the three great wars that prevented them from leaving the country with their families. It may be that this very military consideration induced the English Government to connive at the clearances at first; and interference at any later stage was very difficult. As it is, in the end even the Sutherland evictions[[420]] seem simply to have shifted the population and not removed it. In spite of emigration Sutherland had as many inhabitants at the last census of 1881, as at the first in 1801, namely, above 23,000. Fishing, an industry new to a great part of the highlands, made this phenomenon possible. Fishing villages have grown at the expense of inland farms. But this is not the whole truth. Till the time when free trade began to distend Glasgow and other great towns of Scotland, the highland counties taken altogether had actually increased in population, as compared with what they were in 1801. The subsequent fall is due not to any great clearances or emigrations, but to another cause that had been acting though not conspicuously for some time before. This was migration to the industrial centres of the lowlands. In the days of the Tudors there were complaints in England of the decay of towns, because a strong government had at last made the protection of walled towns superfluous, and industry had spread itself in peace, where it was wanted. But two centuries later there was decay not of the towns but of the country districts, because industry was taking forms that made concentration necessary. At first, both in England and Scotland, there was a real diminution in the rural population; there had been for the time a real diminution of the work to be done in the country, and a transference of it to the towns. The hand-loom weaver had been supplanted by the power-loom. The little villages, where the workman lived idyllically, half in his farm and half in his workshop, now either sent their whole families to the towns, thus stopping their contributions to the parish registers in the country and swelling those of the town, or, still keeping the parents, sent three-fourths of the children there, thus making the country registers a very untrustworthy reflection of the real state of the population in the country districts. That country villages in every part of Scotland, but especially near the large cities, are “breeding grounds” of this latter description[[421]] is perfectly well known; and the same is true, in a less degree, of England. This is one reason why even the purely rural districts of Scotland have greatly increased in apparent population since 1801, and most of them are increasing still; the readiness of the Scotch to emigrate has caused the large families quite as much as the large families the emigration. Another reason is, that even in the country districts there is now more work to be done and it is done better. Orthodox economists may count this an example of the self-healing effects of an economical change that causes much suffering at first. It is fair to say that this eventual cure is neither more nor less complete than the cure of the analogous hardships of the newly-introduced factory system, and the temporary inconveniences of sudden free trade. What keen commercial ambition can do it has done, and its success is at least sufficiently complete to justify us in saying of Scotland to-day what Malthus said of it eighty years ago: it was most over-populated when it had fewest inhabitants. Modern improvements, however short of perfection, have at least both in England and in Scotland absolutely put an end to periodical famines. Even the scarcities of 1799 and 1800, though they caused great distress in both countries, were not famines in either of them; and, since the repeal of the Corn Laws in 1846, even such general distress as was caused in Scotland by the potato blight cannot occur again. That distress itself was as nothing compared with the terrible dearths from which Scotland used to suffer five or six times a century, and which England experienced as late as the seventeenth.[[422]] The dismal picture[[423]] which Malthus draws of the condition of the Scottish peasantry reminds us that it is not much more than a century since Scotland took her first steps in civilization and turned her energies from war to commerce. Her population at the ’45 was about one and a quarter millions, in 1801 about one and a half; but in 1861 more than three, and in 1881 three and three-quarters. Population therefore has more than doubled within the century. But even now there are only a hundred and twenty-one inhabitants to the square mile, as compared with four hundred and forty-five in England. The wealth of the country has increased immensely faster than the population; it has multiplied fivefold since the middle of this century, and tenfold since the beginning of it.[[424]]

The history of population in Ireland would have furnished Malthus with still more striking illustrations of his principles, if his life had lasted a few years longer. He contents himself (till the 6th edition of the Essay[[425]]) with a single paragraph: “The details of the population of Ireland are but little known. I shall only observe, therefore, that the extended use of potatoes has allowed of a very rapid increase of it during the last century. But the cheapness of this nourishing root, and the small piece of ground which, under this kind of cultivation, will in average years produce the food for a family, joined to the ignorance and depressed state[[426]] of the people, which have prompted them to follow their inclinations with no other prospect than an immediate bare subsistence, have encouraged marriage to such a degree, that the population is pushed much beyond the industry and present resources of the country; and the consequence naturally is, that the lower classes of people are in the most impoverished[[427]] and miserable state. The checks to the population are of course chiefly of the positive kind, and arise from the diseases occasioned by squalid poverty, by damp and wretched cabins, by bad and insufficient clothing,[[428]] and occasional want. To these positive checks have of late years been added the vice and misery of intestine commotion, of civil war, and of martial law.”[[429]]

In his review of Newenham’s Statistical and Historical Enquiry into the Population of Ireland in 1808,[[430]] and in his evidence before the Emigration Committee in 1827, Malthus uses even stronger language. We may quote from the latter document as the less known of the two. In 1817 he had spent a college vacation in visiting Westmeath and the lakes of Killarney,[[431]] and was able to speak from personal knowledge of the country. He was asked:—

Qu. 3306. “With reference to Ireland, what is your opinion as to the habits of the people, as tending to promote a rapid increase of population?”—“Their habits are very unfavourable in regard to their own condition, because they are inclined to be satisfied with the very lowest degree of comfort, and to marry with little other prospect than that of being able to get potatoes for themselves and their children.”[[432]]

3307. “What are the circumstances which contribute to introduce such habits in a country?”—“The degraded condition of the people, oppression, and ignorance.”

3311. “You have mentioned that oppression contributes to produce those habits to which you have alluded; in what way do you imagine in Ireland there is oppression?”—“I think that the government of Ireland has, upon the whole, been very unfavourable to habits of that kind; it has tended to degrade the general mass of the people, and consequently to prevent them from looking forward and acquiring habits of prudence.”

3312. “Is it your opinion that the minds of the people may be so influenced by the circumstances under which they live, in regard to civil society, that it may contribute very much to counteract that particular habit which leads to the rapid increase of population?”—“I think so.”

3313. “What circumstances in your opinion contribute to produce a taste for comfort and cleanliness among a people?”—“Civil and political liberty and education.”[[433]]

Then the subject of one acre holdings is introduced, and Malthus is asked:—

3317. “What effect would any change of the moral or religious state of the government of that country produce upon persons occupying such possessions?”—“It could not produce any immediate effect if that system were continued; with that system of occupancy there must always be an excessive redundancy of people, because, from the nature of tolerably good land, it will always produce more than can be employed upon it, and the consequence must be that there will be a great number of people not employed.”
