12 implements and those discarded on account of some fault. The implements at this incomplete stage were distributed (by barter or sale ?) and probably finished by the purchaser. The dead were buried in a mound of earth called a Tumulus or Barrow, or under a heap of stones known as a Cairn. Some- times these are of great size, oval or circular in shape and contain an inner chamber built of slabs of stone, with a tunnel communicating with the entrance. In this chamber the dead were laid, often in a crouched position, which is supposed to be the posture in which the people slept and died. In some cases the body was burnt and the ashes were placed in urns of coarse pottery. Generally speaking the characteristic barrow of this age is oval or long, as distinct from the smaller circular barrow of the Bronze age, and it is noticeable that the skulls found in the former are of the shape known as the long type, while those of the latter are round. The forms of these barrows are supposed to have been derived from those of the habitations of their builders. Some northern races still live in huts, closely resembling the long barrow, made of earth piled over a subterranean chamber—a device to secure warmth. In the Camps of this period are found clusters of circular pits or depressions, which were roofed with constructions of " wattle and daub." These camps or settlements were defended by ditches and ramparts, which were strengthened with a pallisade. The best record of the conditions of life in Neolithic times is furnished by the Lake Dwellings, some of which date from this period, although most of them belong to the succeeding age of Bronze. These dwellings were constructed on piles driven into the lake-mud, or in the shallower lakes and streams on a bed of faggots, earth and stones, secured by stakes and built up just above the water level, making a platform or '• fascine " on which the huts were erected ; a narrow causeway serving to communicate with the shore. These sites are found most commonly in Switzerland, but they also occur over a great part of Europe. In Ireland and Scotland they are known as Cran- noges ; some have also occurred in England. Owing to the peculiar preserving properties of the peaty lake-mud, in which he objects are imbedded, much evidence has been found relating to the people of the newer Stone-age. Remains have been dis-
