PHILLACK, a parish in the hundred of PENWITH, county of CORNWALL, 7 miles (N.E. by N.) from Marazion, containing 2529 inhabitants. The living is a rec- tory, with that of Gwithian annexed, in the archdeaconry of Cornwall, and diocese of Exeter, rated in the king's books at £45. 10. 10., and in the patronage of the Rev. William Hockin. The church is dedicated to St. Felix. This parish includes the port of Hayle, also several villages, the principal of which, Hayle Copper House, carries on a considerable trade in coal, timber, iron, and limestone, imported from Wales; and earthenware, groceries, &c., from Bristol: the chief exports are copper- ore, in considerable quantities, from the western mines. Extensive improvements have been recently made in the harbour by canals, flood-gates, wharfs, Sac.; and a grand causeway, one thousand and forty feet in length, across an arm of the sea, was finished in 1826, at the expense of £7200; a weekly market has been established, and a market-house erected. Here is the largest and most complete iron-foundry and factory in Cornwall, where apparatus for steam-engines of the greatest dimensions are made. The smelting and refining of copper were formerly carried on to a great extent, but within these last few years the works have ceased, owing to the great expense, and the arsenic smoke having been found destructive to the health of the workmen, and to vegetation in general. There is a smelting-house for tin at Argarrack. The great wheal Alfred, which formerly produced one thousand tons of copper-ore per month, and several other mines, are within this parish, though none are at present in operation. The north side of the parish is overwhelmed with sand, blown up from the coast of St. Ive's bay. There was once a castle at Hayle Bar Riviere, and another at Castle Hayle, of which the moat still remains.
