The larger huts had their roofs supported by a central pole, and the socket-hole in which it stood has been found in some of them. In many huts also a flat, smooth stone bedded in the floor has been noticed, presumedly employed as a block on which to chop wood or fashion bone implements. It is remarkable that one specimen only of a spindle-whorl has been discovered. No metal objects have so far been found in the Dartmoor hut circles. Implements of flint, sandstone, and granite abound; they are mostly scrapers, borers, knives, and rubbing or smoothing tools; a few arrow-heads have turned up, but these are mostly outside the huts, probably shot away in hunting. The examination of the graves discloses the same kind of pottery, but with better finish and more elaborate ornamentation. Implements of stone and some bronze objects were yielded by the graves, and the evidence of the exploration of the Dartmoor remains has thus far connected them with the period of culture known as the late Neolithic and Early Bronze Age, which means that the folk were still using stone for their tools and weapons, but were just beginning to employ bronze, an alloy of copper and tin. It is not surprising that bronze has not hitherto been found in the dwellings; it was far too valuable to be left about in such a manner as to be lost, and no surprise need be expressed that it has been discovered in sepulchral monuments appertaining to the same people, for nothing was too good as an offering for the use of the dead in the happy hunting-grounds above. [Illustration: BROADUN POUNDS] That at least some of these huts belonged to "medicine men" is probable, from the finding in them of large, clear quartz crystals, such as are employed by several savage races as mediums for conjuring spirits. Some of the hut circles are enclosed within "pounds." Many examples exist. The most noteworthy is Grimspound. The circumference of the wall measures 1500 feet, and it includes within it twenty-four hut circles. The wall is double, with small openings as doors into the space between, two of which are perfect; but for what purpose the interspace between the walls was left is most uncertain. It can hardly have been filled in with earth or rubble, as no traces of such filling remain. The entrance to the pound is in a very perfect condition. There is a hut circle outside the enclosing wall, just as in the prehistoric forts of Ireland. A curious passage may be quoted from the gloss to the Law of Adamnan, which shows how women were treated among the early races.
