"Phillack, in addition to the copper works at Hoyle, pos-
sesses also a tin smelting house at a village called indiffer-
ently Angarrack or Vellarvrane. It is said to be the first
smelting house established by Becher and the other Ger-
mans for smelting tin ores in reverberatory furnaces by
means of coal. During the life of Mr. William Tremaine
the late managing partner, this place was decorated with the
finest garden in the West of Cornwall. "
