This parish no where reaches so far as the granite hills. Its eastern
part is composed of rocks which pass into the porphyritic series
of St. Breward; the western part rests on the same kind of rocks as
those of the adjoining parish of St. Teath.
[13] No such name appears in the index to Domesday Book; nor should
we expect it. On the contrary, this place is probably the Tewardevi of
the Domesday survey. _Edit._
