The roof was thus gathered in about a smoke-hole, which was itself finally closed with a wide, thin granite slab, and thus the whole roof and sides were buried in turf, so that the structure resembled a huge ant-hill. Most of this encasing flesh and skin has gone, and the bone beneath is exposed. Nevertheless; it does remain in some cases, and has been the means of preserving these curious structures. 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. This Fernaker hut is rudely quadrangular, and one side is formed by a great block of granite rising out of the ground five feet and nine feet long. 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. One huge slab of granite, some twelve feet long and six feet wide, forms half the roof of the larger hut; the remainder has fallen in.
