The famine of 1741 did not deter farmers from the culture of the potato; on the contrary, it increased rapidly after that period, and we now find it, for the first time, recognised as a rotation crop. They preferred to turn their attention to improve its quality and productiveness, and to take measures for its protection from frost, rather than to abandon its culture. And, indeed, it was as much a matter of necessity as choice that they did so. The potato, on a given area, supplied about four times as much food as any other crop; and, from the limited breadth of land then available for tillage, the population would be in continual danger of falling short of food, unless the potato were cultivated to a large extent. The agricultural literature of the country from 1741 until the arrival of the celebrated traveller, Arthur Young, in Ireland, consisted chiefly of fierce attacks upon graziers--of a continual demand for the breaking up of grass lands into tillage--of plans for the establishment of public granaries to sustain the people in years of bad harvests, and of the results of experiments undertaken to improve the culture of the potato. The writers on these subjects also frequently denounced the rich for the wretchedness and misery to which they allowed the labouring poor to be reduced. The author of a pamphlet, which went through several editions, thus attacks them, in the edition of 1755:--"The want of trade and industry causes such inequality in the distribution of their (the people's) property, that while a few of the richer sort can wantonly pamper appetites of every kind, and indulge with the affluence of so many monarchs, the poor, alas! who make at least ninety-nine of every hundred among them, are under the necessity of going clad after the fashion of the old Irish, whose manners and customs they retain to this day, and of feeding on potatoes, the most generally embraced advantage of the inhabitants, which the great Sir Walter Raleigh left behind him."[30] This writer's remarks apply chiefly to Cork, Waterford, Kerry, and Limerick. He proceeds: "The feeding of cattle on large dairies of several hundred acres together, may be managed by the inhabitants of one or two cabins, whose wretched subsistence, for the most part, depends upon an acre or two of potatoes and a little skimmed milk."[31] Many think that the yield per acre of potatoes has greatly increased with time in Ireland. This opinion, although true, is not true to the extent generally supposed; for, when Arthur Young travelled in this country, and even before it, the yield, as far as recorded, seems nearly equal to the quantity produced at present, except in some peculiar cases. A well-known agriculturist, John Wynne Baker, writing in 1765, says, in a note to his "Agriculture Epitomized," that he had in the past year (1764) of apple potatoes (not a prolific kind) in the proportion of more than one hundred and nine barrels an acre.
