It may be observed, that I have always used the words Log-ing Rock,
for the celebrated stone at Trereen Dinas. Much learned research seems
to have been idly expended on the supposed name, “Logan Rock.” To log,
is a verb in general use throughout Cornwall, for vibrating or rolling
like a drunken man; and _an_ is frequently heard in provincial
pronunciation for _ing_, characteristic of the modern present
participle. The Loging Rock is therefore strictly descriptive of its
peculiar motion.
