Hedging & Walling Stone... Blue/Grey and Rustic mixed stone as it comes from the quarry and suitable for roadside, garden and farm hedges. — Delabole Slate, "Landscape and Paving"Coming right uop to date,

A Cornish Slate Wall on the Road from Tintagel to Boscastle, Cornwall. "The Devonian rocks of Cornwall comprise slates and limestones as well as red sandstones," explains Arthur Salmon (2). Looking back to 1900, he could say, "In quarries the duchy employs 5672 persons, and during 1900.... raised 38,485 tons of slate, chiefly at Delabole. These figures show that Cornish quarrying is prosperous, whatever may be said of its minings" (20). One result of this work is the preponderance of attractive dry walls, as shown above, on a herringbone pattern. This one was along a stretch of the B-road between Boscastle and Tintagel.

The Delabole works is still selling slate suitable for such walls. Its history goes back centuries: "Delabole Slate has been used as a building material for some 800 years, and has been quarried continuously since the early 17th century, when Carew in his survey of Cornwall wrote 'in substance thin, in colour fair, in lasting long and generally carrieth good regard.'" What is more, unlike the tin and copper mining industries, it continues to thrive, with "an average of 120 tonnes of slate block" still being quarried each day (Delabole Slate, "History").
