An Anthropogeographical Study of the Origin of the Eskimo Culture. 151 
of mammal-remains do there occur, in addition, the bones of the larger whale- 
species, such as Balena mysticetus, Balænoplera velifera and sibbaldii, the Cali- 
fornian Grey Whale (Rhachianectes glaucus), and the Cachalot or Sperm Whale. 
It is evident from this succession of layers, that the kayak must have existed 
during the whole of the hunting period, and that it must have appeared rather 
suddenly on the scene. And only one possible explanation is in accordance 
with this view, viz., that the kayak has been borrowed from the Eskimo. 
Another point of interest is apparent from the succession of the layers 
viz., that the hunting of the large species of whales with baidare and lances 
with slate blades, — which is also known from Kadiak, but which has not ex- 
tended further north than Aliaska, — is a method of hunting of rather late occur- 
rence. This conclusion is justifiable, as both the bones of the animals hunted 
and the hunting weapons, the whaling lances with slate blades, occur late in 
the succession of layers. Other interesting observations may be made on DALL’s 
investigations, but I shall refrain from further comment, as the sole task we 
have set ourselves here has been to elucidate the fact that the Aleuts are 
members of an originally independent tribe which adopted the implements 
and hunting methods of the Subarctic Eskimo.
