in the work or ceremony. 
It would require a very 
long time to secure a record 
of the various industries 
of a tribe if these were all 
taken as they are actually 
performed as a matter of 
yearly routine. In practice, 
it is necessary to have these 
duties undertaken for the 
special purpose of photo- 
graphing them. When this 
is done, however, it is usu- 
ally possible to allow the 
subjects to assume their 
own poses and _ positions 
even if the result is less 
attractive in arrangement. 
The photographer needs

relation to the source of the 
light. To take the entire 
action of a piece of work 
lasting for several hours, 
such as the preparation of 
the pitch and its application 
to a water basket, involves 
too great an expense and 
more film than can be uti- 
lized. In such cases it is 
necessary to have the cam- 
era constantly in position, 
and to operate it only when 
movements of significance 
occur. It is seldom neces- 
sary to change its position 
for simple industrial acts. 
During a field trip to the 
San Carlos Apache this

Films were made of such 
industries as basket-mak- 
ing, the boiling and applica-
