The words CLAUSUM OPACISSIMA SILVA are decisive. The phrase AB OCEANO MILIARIBUS DISTANS SEX, too, is taken from an earlier passage of the same author, quoted above, which passage may likewise have supplied the identical phrases OCEANO UNDIQUE CINCTUS, and the SPATIUM DUCENTORUM CUBITORUM, which are hardly applicable to St. Michael’s Mount. The “two churches _still_ existing in Mont St. Michel,” had to be left out, for there was no trace of them in St. Michael’s Mount. But the monks who lived in them were retained, and to give a little more life, the wild beasts were added. Even the expression of _antistes_ instead of _episcopus_ occurs in the original, where we read, “Hæc loci facies erat ante sancti Michaelis apparitionem hoc anno factam religiosissimo Autberto Abrincatensi episcopo, admonentis se velle ut sibi in ejus montis vertice ecclesia sub ipsius patrocinio erigeretur. Hærenti ANTISTITI tertio idem intimatum,” etc. Thus vanishes the testimony of William of Worcester, so often quoted by Cornish antiquarians, as to the dense forest by which St. Michael’s Mount in Cornwall was once surrounded, and all the evidence that remains to substantiate the former presence of trees on and around the Cornish Mount is reduced to the name “the Hoar rock in the wood,” given by William, and the Cornish names of _Cara clowse in Cowse_ or _Cara Cowz in Clowze_, given by Carew. How much or how little dependence can be placed on old Cornish names of places and their supposed meaning has been shown before in the case of Marazion. Carew certainly did not understand Cornish, nor did the people with whom he had intercourse; and there is no doubt that he wrote down the Cornish names as best he could, and without any attempt at deciphering their meaning. He was told that “Cara clowse in Cowse” meant the “Hoar rock in the Wood,” and he had no reason to doubt it. Even a very small knowledge of Cornish would have enabled Carew or anybody else at his time to find out that _cowz_ might be meant for the Cornish word for wood, and that _careg_ was rock. _Clowse_ too might easily be taken in the sense of gray, as gray in Cornish was _glos_. Then why should we hesitate to accept _Cara clowse in cowse_ as the ancient Cornish name of the Mount, and why object to Mr. Pengelly’s argument that it must have been given at a time when the Mount was surrounded by a very dense forest, and that _a fortiori_ at that distant period Cornish must have been the spoken language of Cornwall?
