"When they had success in hunting, it was their custom in the forenoon to send their huntsman, with what they had killed, to a proper place, where there was plenty of wood and water; there they kindled great fires, into which, their way was, to throw a number of stones, where they continued till they were red hot; then they applied themselves to dig two great pits in the earth, into one of which, upon the bottom, they were wont to lay some of these hot stones as a pavement, upon them they would place the raw flesh, bound up hard in green sedge or bulrushes; over these bundles was fixed another layer of hot stones, then a quantity of flesh, and this method was observed till the pit was full. In this manner their flesh was sodden or stewed till it was fit to eat, and then they uncovered it; and, when the hole was emptied, they began their meal."[7] [Illustration: FLINT SCRAPERS. (Actual size.)] Some of the huts are very large, and in these no traces of fires and no cooking-holes have been found. Adjoining them, however, are smaller huts that are so full of charcoal and peat ash and fragments of pottery that no doubt can be entertained that these were the kitchens, and the large huts were summer habitations. [Illustration: COOKING-POT.] Occasionally a small hut has been found with a large hole in the centre crammed with ashes and round stones, the hole out of all proportion to the size of the hut if considered as a habitation. No reasonable doubt can be entertained that these were bath huts. The Lapps still employ the sweating-houses. They pour water over hot stones, and the steam makes them perspire profusely, whereupon they shampoo themselves or rub each other down with birch twigs. Indeed, men wearing skin dresses are obliged to go through some such a process to keep their pores in healthy action. It is very probable that the long tracklines that extend over hill and vale on Dartmoor indicate tribal boundaries, limits beyond which the cattle of one clan might not feed. Some of these lines, certainly of the age of the Neolithic men of the hut circles, may be traced for miles. There is one that starts apparently from the Plym at Trowlesworthy Warren, where are clusters of huts and inclosures. It follows the contour of the hills to Pen Beacon, where it curves around a collection of huts and strikes for the source of the Yealm by two pounds containing huts. That it went further is probable, but recent inclosures have led to its destruction. We cannot be sure of the age of these tracklines unless associated with habitations, as some very similar have been erected in recent times as reeves delimiting mining rights.
