One such, very perfect, is on the river Erme, above Piles Wood, on Dartmoor. Into this it is quite possible to crawl and take refuge from a shower. It is completely watertight, but it is not easy to find, as it is overgrown with dense masses of heather. Another is close to the farmhouse of Fernaker, between Brown Willy and Rough Tor, and it has been spared because the farmer thought it might serve his purpose as a pig-sty or a butter-house.

On this basis the house has been built and roofed in the usual manner by five courses of overlapping stones. The highest peak of Brown Willy is occupied by a huge cairn that has never been explored, owing to the expense and labour of working into it. It probably covers some old Cornish king. Immediately below it, some forty feet, are two beehive huts, in very fair condition, one eight feet in diameter, with a second, much smaller, only four feet six inches in diameter, close to it, opposite the door, with an entrance so small that it probably served as a store -chamber.
