The Geology of this parish has nothing peculiar or characteristic. Dr. Boase remarks that the eastern part is a continuation of the barren downs which extend nearly to Lostwithiel, and that the southern, which is the fertile part, belongs to the calcarious series of the schistose group, but that the rocks are too much concealed under the alluvial soil to allow of their nature being very evidently manifest.

For these 433 grains of diamond, the Regent Duke of Orleans is stated to have given 135,000l. or two thousand eight hundred and eighty-nine pounds troy of standard gold, or nearly one ton one hundred and a quarter avoirdupoise; above thirty-eight thousand four hundred times its own weight, or seven thousand five hundred and eighty times its bulk.
