46 FIRST FLOOR 
The hall is too feet square and can seat an audience of 1,500 
people. It is provided with two screens, each 25 feet square, and 
the illustrations for the lectures are projected by means of two 
double electric stereopticons. 
Leaving Hall No. 108 at the south end we pass to the West 
Corridor (No. 103). Here, extending upward through three 
stories of the building, is a Haida totem-pole, 52 feet tall, from 
Queen Charlotte Island. 
Continuing toward the west, North American Hall (Hall No. 
102) is entered next. The collections in the south side of this 
North hall represent in sequence the cultures of the Indians 
American of the Plains, of the Eastern Woodlands and of part 
Hall. of the Southwest. The visitor is recommended to 
begin here in continuation of the studies which he has made in 
the North Wing (No. 108). 
The collections from the Plains Indians have largely been 
made from the point of view of illustrating their decorative art 
The Plains and their ceremonials. The first case on the south side 
Indians. (Case 17) contains material from the Blackfoot. This 
is followed by collections from the Cheyenne (Case 18), Arapaho 
(Cases 18-21), Gros Ventre (Cases 21, 22), Sioux (Cases 23-26), 
Shoshone (Cases 27-28), and Ute (Case 29),—all representatives 
of the Plains culture. 
These tribes originally subsisted on the buffalo, and conse- 
quently most of their utensils pertain to the preparation of skins 
and to the manufacture of implements of bone (Case 19). The 
present ceremonials of the Plains tribes are much modified by 
the teachings of recent Indian prophets, which have taken the 
form of the so-called “‘Ghost dance,”’ the paraphernalia of which 
are exhibited in Cases 19 and 20. Bags containing certain sacred 
objects are much used. Such a sacred bag is in a case in the 
center of the hall. Among many tribes there exist societies 
grouped according to ages, which perform ceremonial dances, 
each with separate paraphernalia; the objects pertaining to four 
such dances are shown in the wall-case, south side of hall.
