The important influence which has been exercised by this root over the destinies of the human race, arises from the fact that it yields an unusually abundant produce as compared with the extent of ground cultivated, and with the labour, capital, and skill bestowed upon its cultivation. The same land, which when laid down to corn, will maintain a given number of persons, will support three times that number when used for raising potatoes. “A family in the West of Ireland, once located on from one to three or four acres of land, was provided for; a cabin could be raised in a few days without the expense of a sixpence; the potatoes, at the cost of a very little labour, supplied them with a sufficiency of food, with which, from habit, they were perfectly content; and a pig, or with some, a cow, or donkey, or pony, and occasional labour at a very low rate of wages, gave them what was necessary to pay a rent, and for such clothing and other articles as were absolutely necessary, and which, with a great proportion, were on the lowest scale of human existence. The foundation of the whole, however, was the possession of the bit of land; it was the one, and the only one thing absolutely necessary; the rent consequently was high, and generally well paid, being the first demand on all money received, in order to secure that essential tenure; and only what remained became applicable to other objects. Although of the lowest grade, it was an easy mode of subsistence, and led to the encouragement of early marriages, large families, and a rapidly-increasing population, and at the same time afforded the proprietor very good return of profit for his land[3].”
