'Cornwall is a different country. Travellers can sense the change as they journey out beyond the Tamar Bridge into a landscape of wooded valleys and granite outcrops.
And to Treloar, south east Cornwall was a very different country from his homelands on the north west coast.
This was an alien terrain, a land of wooded valleys, fingers of water probing inland from the sea; the rivers Looe, Fowey, Helford and the Fal, daddy of them all. It was a sheltered, confined, shaded and enclosed land.
He was a man of the high windswept moorland, exposed, exhilarating endless horizons, fingers of land poking out into the sea; Cape Cornwall, Gurnard’s Head, Zennor Head. He was a foreigner here. He felt unsettled.
