In a dingle called Chapel-comb, was an ancient chapel known by the name of Porth Chapel, the ruins of which were taken down about the year 1780. Near this spot is St. Agnes’ well, of which many miraculous stories are told; the water is of an excellent quality, and much esteemed. Hals speaks of an ancient free chapel in the manor of Mythian, which had been made a dwelling house. There are remains of an ancient chapel at Mola. Nicholas Kent, of Mingoose, by his will bearing date 1688, gave for the term of 499 years a dwelling house, divided into four tenements and a garden, for poor widows of this parish, and charged his lands of Mingoose and Tereardrene with the repairs of the house; but it does not appear that it was endowed. One of the schools, founded by the trustees of the fund left for charitable uses by the Rev. St. John Elliot, who died in 1760, is at St. Agnes; the endowment is £5 per annum. There is a Sunday school at St. Agnes, supported by subscription, and numerously attended. THE EDITOR. For various particulars respecting the Tonkin family see the edition of Carew by Lord Dunstanville, vol. I. 1811, 4to. pp. 353-357, with monumental inscriptions in St. Agnes church. The arms of Tonkin are noticed in a copy of the last Heraldic Survey, communicated to the Editor by Mr. Gregor of Trewanthenick, although a pedigree is alone recorded in the original. Sable, an eagle displayed Or, armed and langued Gules, a crescent for difference. Crest, an eagle’s head erased Or. See the exemplification of them by Robert Cooke, Clarenceux Roy d’Armes, temp. Reg. Eliza. The reason of the arms being then omitted was this: Mr. Tonkin of Trevannence, the chief representative of their family, was more than eighty years of age in 1620, a bed-lier, and had been blind for many years, so that he was not able to appear himself; and, the chief business of the Heralds at their Visitations being to put money into their own pockets, they never registered any arms without their fees. The ancient motto used by this family is said to have been: Kenz ol tra, Tonkein! ouna Deu, Mahteror yn. (Before all things, Tonkin! fear God, the King also.) St. Agnes contains 6,657 statute acres.

GEOLOGY, BY DR. BOASE. This parish is one of the great mining districts of Cornwall, abounding in tin and copper ores, but more particularly in the former. It differs, however, from all the other districts, in being remote from the great central masses of granite. This peculiarity has often attracted the notice of several observers, and has long been considered as a strange anomaly by geologists.
