They were probably erected in com- memoration of the dead and are always associated with cairns and interments.

Very curious are the clusters of communal huts at Chysauster, Bosporthennis, etc. They probably belong to the Iron Age, whereas the hut circles scattered over a hill side, or within a pound, pertained to the early Bronze Age. Arrow heads, lance heads and scrapers have been found in tolerable abundance on the Bodmin moors, on Cam Brea, at St Agnes, etc., and celts (axe heads) of greenstone and diorite have occurred, but not with great frequency. At Harlyn Bay has been found a cemetery of the Iron Age, all the bodies in slate cists, crouching. In the cairns and kistvaens (stone coffins) on the other hand the bodies have been burnt. Numerous urns of the well- determined Bronze Age type have been recovered from cairns. The camps of stone and earth in Cornwall are very numerous. They all or nearly all date back to the
