Relics of the Bronze Age are far more abundant, and they form, indeed, the chief archaeological feature of Devonshire. Dartmoor in particular, chiefly perhaps because its great upland wilderness has never been broken up by the plough, is dotted all over with remains of primitive Bronze Age dwellings, sometimes standing alone, sometimes grouped in villages and surrounded by a wall, and also with many stone circles, tumuli, kistvaens, menhirs, and rows of upright stones. It is, moreover, intersected by a network of ancient trackways, linking settlement to settlement. [Illustration: Palstave of the Bronze Age (_In Exeter Museum_)] The best example of an early Bronze Age village is Grimspound, eight miles north-east of Princetown. It consists of twenty-four round huts made of stone slabs set on end and standing about three feet above ground, scattered over a space of about four acres, surrounded by a nearly circular double wall, from nine to fourteen feet thick, and about five feet high, built of blocks of granite, some of which are tons in weight. Half the huts contain fire-hearths, which have been much used; and a good many have raised stone benches, from eight inches to a foot high. Except that the roofs, which were no doubt made of poles and thatch, have disappeared, these primitive dwellings, of which there are hundreds on Dartmoor, are probably much in the same condition as when they were inhabited, perhaps 2000 years ago. It has been suggested that Grimspound, like many ancient camps or hill-forts, was a place of refuge in times of danger, rather than a permanently occupied fortress. [Illustration: Fernworthy Circle, near Chagford] The objects found in these and similar dwellings consist of flint implements, pottery--some of it decorated--spindle-whorls, and cooking-stones such as are still in use among the Eskimo. So far, no fragment of metal of any kind has been discovered, from which it might, perhaps, have been inferred that the huts were the work of a race unacquainted with the use of metal. But the pottery so closely resembles that found in the burial-mounds of the Bronze Age that archaeologists are satisfied that the dwellings belong to that period.
