PRIMITIVE ART 15 
a series of diamonds represents isolated lakes, and lakes con- 
nected by streams. Near these lakes are shown ducks flying 
towards the water. Designs half pictographic and half geo- 
metrical may also be seen on the baskets in Case O 9, in which 
the figures of birds, men and dogs may be recognized. A 
striking interpretation is given for two baskets in Case O 11. 
The peculiar rectangular forms which face each other are each 
interpreted as a head. In one of these, the short lines on the back 
represent the hair, while the two pairs in each opening represent 
teeth. In the other one these attachments have entirely dis- 
appeared, but the form is still interpreted as that of two heads 
facing each other.
