Below Lanteglos is the manor of Helston, and Domesday records "that there were forty brewers on the royal manor of Henliston." This is the only mention in the great survey of brewers as an item of population, and forty seems a good many for one place. Did they brew all the beer in the county; and was it Henliston ale that so appalled Andrew Borde when he thought to visit Cornwall, that he turned back saying: "it looked as if pigges had wrasteled in it"?
Camelford is not far from either of the sources of the Camel, and the upper moorland reaches of the twin streams abound in charming spots where the water frets among boulders and swirls in sunshine and shadow among ferns and wild flowering shrubs. The sisters do not join forces till they reach Kea Bridge, over ten miles from their source, but as soon as depth allows of their existence sweet small trout are plentiful.
Between Camelford and Tintagel are the now silent quarries of North Delabole (or Dennyball). The road winds between great walls and under archways of slate which look as if a touch would send the whole erection sliding and rushing down upon the wayfarer. But the slates were set up by cunning fingers and have withstood the gales of this coast for a score of years. Very different is their mournful creeper-grown desolation from the arid activity of Delabole. The approach to the high grey windy street is marked by deep ferny lanes. Here are thirty acres of quarry and rubble heap, a hideous excavation. In 1602 the quarry, already old, was 900 ft. long, in 1882 it had grown to 1300 ft., and it is growing still. The best slate is called bottom stone and lies at a depth of from 25 to 40 fathoms, for the quarry is now over 400 ft. deep. Beautiful crystals the so-called Cornish diamonds, are found in these workings, truly the only beautiful things in a most dreary place.
When the church at little sleepy St. Teath was restored in 1877, two massive Norman responds at the east end of the north aisle were discovered. There is also some good roof timber and a little ancient glass. The pulpit bears the arms of the Carminows and their motto: "Cala Rag Whetlow"--a straw for a tell-tale. It was John of Gaunt, "time-honoured Lancaster," that Prince who, though never a king, was the ancestor of so many, who upon true evidence found Carminow of Cornwall "to be descended of a lineage armed 'Azure a bend Or' since the time of King Arthur;" and indeed the Carminows were certainly here at the Conquest. They are now extinct, the last of the family, a devoted Royalist, dying in 1646.
