faults, which are the invariable products of arbitrary control over human beings, but there the physiological gulf between the dominant and subject race was too broad and deep to permit of substantial deterioration in the former. In Ireland the ethnological difference was small; the artificial cleavage and deterioration great in inverse proportion. For the greater part of a century, in every part of Ireland, tenancies of land, whether held by Catholic or Protestant, by lease or at will, were alike in certain fundamental characteristics. The tenant had neither security of tenure nor right to the value of the improvements which were invariably made by his own capital and labour. Even a leaseholder, when his lease expired, had no prescriptive claim to renewal, but must take his chance at a rent-auction with strangers, the farm going to the highest bidder. If he lost, he was homeless and penniless, while the fruits of his labour and capital passed into other hands. The miserable Catholic cottier was, of course, in a similar case, though relatively his hardship was less, since his condition, being the lowest possible in all circumstances, could scarcely be worse. Obviously, in a case where the landlord was neither the capitalist nor the protector and friend of the tenant, the possession of those elementary rights, security of tenure and compensation for improvements, was the condition precedent to the growth of a sound agrarian system. Their denial was incompatible with social order. Yet they were denied, and for one hundred and eighty years an intermittent struggle to obtain them by violence and criminal conspiracy degraded and retarded Ireland.
