But it must be further observed, that it is not merely in the matter of religious instruction that the Nonconformists have become almost exclusively the leaders of the Welsh people. As respects literature and science, and all important social and political movements, it is the same. The literature of Wales, and not its religious literature merely, is almost wholly Nonconformist. There are about thirty periodicals, quarterly, monthly, and weekly, at present published in the Welsh language. Of these all but three are owned and edited by Dissenters. There are nine commentaries on the whole Bible, and nine besides on the New Testament alone, some original and some translated from English, and only two of these were done by Churchmen, and even they were Dissenters when they began their work. There are eight Biblical and Theological Dictionaries, and as many bodies of divinity or systems of theology, and no Churchman, we believe, has had a hand in the production of any one of them. There is a History of the World, a History of Great Britain, a History of Christianity, a History of the Church, a History of the Welsh Nation, a History of Religion in Wales, all by Dissenters, besides elaborate denominational Histories of the Calvinistic Methodists, the Independents, the Baptists, &c. Indeed, all the ecclesiastical histories in the language are Nonconformist, and all the general histories except the History of Wales by the Rev. Thomas Price, and a small work called the 'Mirror of the Principal Ages.' There is a valuable work illustrated by many excellent maps and diagrams, entitled 'The History of Heaven and Earth,' treating of geography and astronomy, by the Rev. J. T. Jones, of Aberdare, formerly a Nonconformist minister. There is another large geographical dictionary in course of publication by a dissenting minister. There are two copious Biographical Dictionaries edited and principally written by Dissenters. There is now, and has been for several years, in course of publication an Encyclopædia in the Welsh language (Encyclopædia Cambrensis), dealing as such works do with the entire circle of human knowledge. It was described by the late Archdeacon Williams, who had seen the earlier volumes, as 'a work of great promise, as sound in doctrine as it is unsectarian in principle.' It is studiously free from denominational taint, and was intended to be a great national undertaking, the contributors being indiscriminately selected from the ablest writers of all denominations, the combined learning and talent of Wales being thus engaged in its preparation. The enterprising publisher at the outset addressed a letter to all those among his countrymen of whatever church or creed who had distinguished themselves in any way by their literary acquirements and productions, inviting their co-operation. We have now before us a list of the contributors amounting to ninety names, and out of these ninety, there are certainly not more than nine churchmen.
