A small grain of fact will suffice at times for the crystallisation of vague and visionary fancies into a well-credited tradition. Before the printing-press came into play, with its perpetuation of definite records, and prosaic sifting of evidence, this was no uncommon occurrence; but even in recent times fancy may be seen transmuted into accepted fact. When exploring the great earthworks of the Ohio valley, in 1874, I found myself on one occasion in a large Welsh settlement, a few miles from Newark, where a generation of native-born Americans still perpetuate the language of their Cymric forefathers, and conduct their religious services in the Welsh tongue. My attention was first called to this by the farmer, who had invited me to an early dinner after a morning’s digging in a mound on “The Evan’s Farm,” preceding our repast with a long Welsh grace. From him I learned that the district had been settled in 1802 by a Welsh colony; and that in two churches in neighbouring valleys—one Calvinistic Congregational and another Methodist,—the entire services are still conducted in their mother tongue. Such a perpetuation of the language and traditions of the race, in a quiet rural district, only required time and the confusion of dates and genealogies by younger generations, to have engrafted the story of Prince Madoc on the substantial basis of a genuine Welsh settlement. Southey’s epic was published in 1805, within three years after this Welsh immigration to the Ohio valley. The subject of the poem naturally gave it a special attraction for American readers; and it was speedily reprinted in the United States, doubtless with the same indifference to the author’s claim of copyright as long continued to characterise the ideas of literary ethics beyond the Atlantic. But the idea of a Welsh Columbus of the twelfth century was by no means received with universal favour there. Southey quoted at a long-subsequent date a critical pamphleteer who denounced the author of _Madoc_ as having “meditated a most serious injury against the reputation of the New World by attributing its discovery and colonisation to a vagabond Welsh prince; this being a most insidious attempt against the honour of America, and the reputation of Columbus!”
