On nearly every recurrence of an inscription in any linear form of alphabetic character brought to light in the western hemisphere, the first idea has been to suggest a Phœnician origin; and this is, no doubt, implied in the statement of its runic decipherer, in the _Proceedings of the American Philosophical Society_, that “the glyphs have been at various times copied and sent abroad to men of learning who have made more or less attempts at deciphering them, more than one savant seeing traces of Semitic origin.” But latterly with the reported discovery of any linear inscription on the eastern seaboard, the temptation has been to refer it to the Northmen of the eleventh century. To this accordingly the allusions of both of my Nova-Scotian correspondents pointed. But the characters of the Scandinavian futhork are sufficiently definite to satisfy any one familiar with Scottish and Manx runic inscriptions, or with Professor George Stephens’ ample illustrations of them as they are found in the native home of the Northmen, that it is vain to look to either for a key to the graven legend on the Yarmouth rock. The presence of the Northmen, not only in Iceland and Greenland, but as transient visitors on some portion of the North American mainland, now rests on satisfactory historical evidence. In Greenland they left indisputable literate records of their colonisation of the region to which they gave the inapt name it still retains. The runic inscriptions brought to Copenhagen in 1831 not only determine the sites of settlements effected by the companions and successors of Eric, but they serve to show the kind of evidence to be looked for, alike to the north and the south of the St. Lawrence, if any traces yet survive of their having attempted to colonise the old Markland and Vinland, whether the latter is recovered in Nova Scotia or New England. Their genuine memorials are not less definite than those left by the Romans in Gaul or Britain; and corresponding traces of them in the assumed Vinland, and elsewhere in the United States, have been perseveringly, but vainly, sought for. One unmistakably definite Scandinavian inscription, that of the “Huidœrk,” professedly found on the river Potomac, does not lay claim to serious criticism. It was affirmed to have been discovered in 1867 graven on a rock on the banks of the Potomac; but to any student familiar with the genuine examples figured in the _Antiquitates Americanæ_, it will be readily recognised as a clever hoax, fabricated by the correspondent of the _Washington Union_ out of genuine Greenland inscriptions. It reads thus: =hir huilir syasy fagrharrdr avstfirthingr iki a kildi systr thorg samfethra halfthritgr gleda gvd sal henar=. To this are added certain symbols, suggested it may be presumed by the Kingiktorsoak inscription, from which the translator professes to derive the date A.D. 1051.
