From an economic and industrial stand-point the condition of Catholics, in relation to land, was the chief cause of the wretchedness of the country. The agricultural laborers were in the lowest social state in Europe, scarcely excepting the Russian serfs. Employment was precarious and rarely secured a higher average wages than sixpence to eightpence a day, or scarcely a dollar a week. From Connaught a large number went to England for some weeks at the hay, corn, and potato harvests, where they earned what paid the rent of the cabin and the potato-plot; while many of the cotters and small farmers were little better in position. A few facts from the census of 1841 and 1851 will suffice to illustrate the large number and the terrible fate of these classes, as indicated by the grades of house accommodation before and after the famine:

Fourth (cabin) class625,35642.5284,22923.5
Total1,472,739100.01,204,319100.0

Here we see that, seemingly in ten but really in five years, no less than 341,127 fourth-class houses—mud, sod, or stone, thatched cabins with only a single apartment—were swept away, inhabited by that number of families, which included about 1,800,000 persons; while the table of population above given shows that in these years the estimated decrease was 1,780,588—a striking concurrence between both. Another proof as regards the class swept away is found in the following table of agricultural holdings, grouped by extent, in 1841 and 1851:

Total691,202608,066

Excluding the very large number of holdings under an acre not ascertained in 1841, we find the disappearance in that decade, or rather in half of it, of 222,353 tenements between one and five acres, which represents a diminished population of 1,200,000 persons. The decrease of 60,945, in the tenements from five to fifteen acres, representing about 320,000 people, is portion of this same subject. If we now turn to another head of evidence we find that the population was thinned from the least educated classes. The census of 1841 returned fifty-three per cent. of the whole population, aged five years and upwards, as illiterate, being unable to read or write, while the return for 1851 showed a decrease to forty-seven per cent.; and turning to the great decrease in the percentage of the Irish-speaking population between 1841 and 1851, we find similar results. Lastly, the creed census demands attention.

The first taken in Ireland was that by the Royal Commission of Public Instruction in 1834, when, of a population of 7,954,100, it was found there were 6,436,000, or 80.9 per cent., Catholics; while the followers of the intruded Anglican Church, established for three centuries, numbered only 853,160, or 10.7 per cent. The adherents of the Scotch Presbyterian Church, endowed by the state, though not established, 643,058, or 8.1 per cent.; and all other Protestant dissenters mustered only 21,822 or 0.3 per cent. Between 1834 and 1845, when the potato blight first appeared, the population had increased from 7,954,100 to 8,295,061, during which period of eleven years there are ample evidences to prove that the Catholic element underwent a larger increase than the Protestant, so that we may fairly assume the whole population in 1845 to have been thus composed:

PER CENT.
Catholics6,760,47581.5
Protestants1,534,58618.5
——————
Total8,295,061100.

These millions of Catholics, emancipated only sixteen years, were the descendants of the natives who for over six centuries had battled against English domination; whose estates and lands had been wrested from them and given to soldiers and adventurers from England and Scotland—“the scum of both nations”; whose ancient church had been despoiled of her property; to whom education was denied and the profession of their faith made penal; whose manufacturing industries were suppressed by English laws; who were excluded from all offices, civil and military, and from all social rank and distinction, and denied not alone a seat in Parliament for 137 years, 1692 to 1829, but from 1727 to 1793, a period of 66 years, the right to vote.

Such is a broad outline of the main facts concerning the population of Ireland in 1845, as to quantity and quality. We must, however, supplement these by a few particulars.

From one-third to one-half the rental of the kingdom went to absentee and alien landlords, who spent it in England or on the Continent. The imperial taxes borne by Ireland were in excess of her capacity and in violation of the articles of the Act of Union. All the state departments had their headquarters in London, while Ireland had slender share either in the appropriating or the enjoyment of those taxes. The local taxation, through grand jury and other cess, was enormous, but levied and appropriated by the country gentry, all predominantly Protestant. The county officers, the grand jury, the jail, the lunatic asylum, infirmary, and poor-law union boards were almost exclusively Protestant. The corporations, reformed by statute in 1840, were still Protestant. One or two Catholic judges had reached the bench, as O’Loghlen, and many Catholics were pressing to the front at the bar and in medicine, while in all the professions, in trade, and in commerce Catholic influence was beginning to be felt. Catholics had, it is true, only trifling share in the administration of the government and the laws. They had little representation in the magistracy or on the grand juries; while jury-packing was the normal condition of the administration of justice. The Orange system, stimulated by the triumph of Catholic emancipation, was rampant and aggressive at the prospect of social equality.
