The character of the water and marsh plants shows that, at 
least at Robenhausen, the lake-dwellings were not erected over 
the deep and clear water of the lake, but on muddy shallows 
overgrown with vegetation. 
See Plate Ixxxviii, Case K 4, for figures of seeds of other 
water and marsh plants found in the pfhalbauten.

The lake-dwellings were probably inhabited during the whole 
year, as the undigested remains of food appear to prove. The 
cherry-stones indicate June ; the seeds of raspberries and black- 
berries the middle and end of summer ; the sloes and the seeds 
of the dog-rose the latter part of autumn ; and the hazel nuts 
and beech nuts refer to the autumn and winter. The presence 
of remains of the swan, a bird which only appears in the Swiss 
lake district during very cold winters, in the months of Decem- 
ber and January, proves that the lake-dwellings were not 
abandoned even in the most severe winter weather.

In this Case flint implemxents and worked flints are 
exhibited. The flint used by the lake-dwellers was pro- 
bably obtained by barter. This is quite in accordance with 
what is known to be the practice of modern savages. In
