This great increase of Population is owing to Perran having become a mining parish, and to the cultivation of an extensive piece of waste ground by individuals, constructing houses on portions of land not exceeding one or two acres, granted on leases for their lives. A spot on this formerly open ground, was called Chapel an Crouse, the chapel and cross; but no record nor trace remains of any such an establishment. Near the same place a bowling green existed about fifty years ago, which is said to have been frequented fifty years prior to that period, by all the gentlemen of the neighbourhood.
Present Rector, the Rev. W. M. Johnson, presented in 1815 by Sir J. Trevelyan.
