Dr. Boase observes on the geology of this parish, that it has the same
geological structure as the contiguous parishes of Creed and Cornelly.
On the parish of Cornelly Dr. Boase states that the prevailing rock is
a fissile blue slate; that it probably contains beds of massive
lamellar rocks; and that all belong to the calcareous series.

P.S. It should have been noticed that the late Mr. Tremayne greatly
improved the house built at Heligon by Serjeant Tremayne; that his son
has carried the improvements still further, and rendered the whole
place one of the finest in Cornwall.
