The agrarian problem has caused more trouble in Ireland than any other, and statesmen have long recognised that on its definite settlement depends the hope of permanent peace and progress over the greater part of the country. It is not, and never has been, the real cause of rural depopulation, for, as we have seen, the increase of the rural population was most rapid at the time when agrarian conditions were at their very worst, whilst on the other hand emigration continues almost unchecked in counties where the question has been virtually settled. And in 1881 the late Mr. J.H. Tuke discovered by an analysis of the census returns that the only "townlands" in which the rural population was actually increasing were those scattered along the western seaboard of Ireland, where the tenure and the conditions of existence seemed most hopeless. But, as the Devon Commission announced in 1845, it was an essentially defective system of land tenure that lay at the root of the perennial discontent with which Ireland was troubled, and things went from bad to worse until the Party organised for the defence of the Union and the social betterment of Ireland took up the task of settling the question by the transfer on fair terms of the ownership of the soil from the large landowners to the tenants. The system of land tenure in England has been the growth of custom gradually hardening into law; in Ireland the traditional custom was suddenly abolished, and English law substituted in its place. The English law was no doubt a better law, and one more fitted to a progressive community; but in Ireland it violently upset the traditional law of the country, and, consequently, was met with sullen and unremitting hostility. By Irish law, the tribe was owner; the tribesmen were joint proprietors, and the forfeiture of the chief did not involve the forfeiture of the land occupied by the tribesmen. By English law, however, these latter, such of them as were not expelled or exiled, suddenly found themselves transformed from joint-owners into tenants at will. Further, the difficulty of dealing direct with tenants, experienced by landlords who were in very many cases absentees, led to the abominable "middleman" system by which the owner leased great stretches of land to some one who undertook to "manage" it for him, and who in turn sub-let it in smaller patches at rack-rents to those who, to get back their money, had to sub-let again at still higher rents. The result was, as an official report in the eighteenth century states: "It is well known that over the most part of the country, the lands are sub-let six deep, so that those who actually labour it are squeezed to the very utmost." And Lord Chesterfield, when Viceroy, complained of the oppression of the people by "deputies of deputies of deputies." The eighteenth-century policy of checking or suppressing the industrial enterprises of the English colony aggravated the evil until, as Lord
