FIRST FLOOR 45 
The material in Alcove 14 is so arranged as to bring out as 
strongly as possible the contrast between the culture of the 
coast and that of the interior. The cases contain eX- The Plateau

with painted geometrical designs and with pictographic repre- 
sentations. Here we also find specimens illustrating the use of 
the horse. The clothing exhibited in Alcove 15 shows the close 
affiliations of this culture with that of the Plains Indians. The 
garments are made of skin decorated with feathers, painted and 
embroidered. The similarity of culture with the eastern Indians 
is still greater among the Plateau tribes near the Columbia River 
(Alcove 16). Here we notice painted hide bags, embroidered 
blankets and bead-work quite similar to that of the eastern 
Indians. The tribes of this district also excel in basketry 
similar in type to that of the interior of British Columbia. 
The contrast between the occupations and the dress of the 
coast tribes and those of the interior is brought out in three 
groups in the middle of the hall. 
The desk cases along the center of the hall contain archzo- 
logical collections. The southern cases exhibit material from 
the plateau region, while the northern cases contain = archeo- 
material from the coast region. It seems that, on the logical 
whole, the culture of the prehistoric tribes has been Material. 
the same as that of the present tribes. 
Most of the material in this hall was obtained by the Jesup 
North Pacific Expedition. 
From the north end of Hall No. 108 one passes through the 
North Corridor (No. 109) into the Lecture Hall (main floor), 
This is the center of great activity during the fall, Pektnce 
winter and spring months. Regular courses of lec- Hall. 
tures are given on Thursday evenings by members of the scien- 
tific staff to Members of the Museum, on Saturday mornings to 
the teachers in the public schools (in co-operation with the State 
Department of Public Instruction), on Tuesday and Saturday 
evenings to the general public (in co-operation with the City 
Board of Education), and on other occasions as need arises.
