LAKE-HABITATIONS OF THE BRONZE AGE. 157 



Another skull shown to me by Professor Desor, and found 

 ut Auvernier, completes the number mentioned by Dr. Keller. 

 All these settlements, however, appear to have belonged to 

 the Bronze age, nor has it yet been possible certainly to 

 refer many of the ancient tumuli found in Switzerland to the 

 earlier period. 



Passing now to the Lake-habitations belonging to the 

 Bronze age, we find that they are less generally distributed 

 than those of the earlier period. They have as yet been 

 found only on the Lakes of Geneva, Luissel, Neufchatel, 

 Morat, Bienne, and Sempach ; none in eastern Switzerland. 

 It has been supposed from this that the age of Stone 

 lasted longer in the east than in the west, and that flint 

 and serpentine were in use on Lake Constance long after 

 bronze had replaced them on the western lakes. We can, 

 however, hardly suppose that the inhabitants of Inkwyl and 

 Moosseedorf in Berne, who imported flint from France, can 

 have been ignorant of the neighbouring civilisation on the 

 Lake of Bienne. Perhaps, however, settlements of the 

 Bronze age may yet be found on the Lake of Constance ; 

 but as the question now stands, Pileworks of the Metallic 

 period are peculiar to western and central Switzerland. The 

 constructions of the latter period are more solidly built, but 

 do not otherwise appear to have differed materially from 

 those of the Stone age. They are often, however, situated 

 farther from the land and in deeper water, partly no doubt 

 on account of the greater facility of working timber, but 

 partly also, perhaps, because more protection was needed as 

 the means of attack were improved. The principal imple- 

 ments of bronze are swords, daggers, axes, spear-heads, 

 knives, fish-hooks, sickles, pins, rings and bracelets. The 

 number of these articles which have been discovered is 

 already very great, the collection of Col. Schwab alone con- 

 taining no less than 4346 objects of metal. They are classi-
