giving an increase of about 40¾ per cent. in 30 years.
The parish feast, like that of St. Columb Major, is on the Sunday nearest to the 17th of November.
GEOLOGY, BY DR. BOASE.
On the eastern side adjoining to the Downs, the rocks are quartzose, but the greater part of this parish is composed of slates belonging to the calcareous series, which extend to the sea shore. At Tremper Bridge, and in the islands lying at the entrances of St. Columb Porth, beds of black limestone occur, associated with talc, schist, and blue slates.
The most interesting feature, however, of this parish
is the testaceous sandstone at New Quay, and on the shores of Fistral Bay. The land adjacent to the sea at those places is covered with sand, which above high-water mark is lapidified, as is also a bed of pebbles on which the sand sometimes rests. For the particulars of this phenomenon the first and the fourth volumes of the Cornwall Geological Transactions may be consulted.
CONSTANTINE.
HALS.
Is situate in the hundred of Kerrier, and hath upon the north, part of Stithians; west, Gwendron; south, Hayleford channel and Mawnan; east, Mabe and Budock. It is also commonly Cus-ten-ton, i. e. wood-stone town, a place heretofore notable for woods and stones, and I take it an unpleasant strag of moor-stones and rocks are still visible upon a great part of the lands here. Perhaps it is the Crostedeton mentioned in the Domesday Roll. Otherwise it was taxed under Trewardevi or Penwarne. The name Constantine is derived from the Latin Constantia.
