The motive in this region is so strong that it has been convey- 

 ed to Oklahoma by the central Algonkian tribes who have moved 

 there, and it is now to be seen in the art of the Osage (Plate 

 XVIII,) Kansa, and other southern Plains tribes. No in- 

 formation is, however, available from the collectors regard- 

 ing possible interpretation or symbolism. 



Summary. 



The accompanying map (Fig. 25) shows some general 

 conclusions on the distribution of the prevailing types of designs. 

 The tribal designations, however, only give general locations, 

 not by any means the tribal boundaries. 



As a start in the study of the distribution of art motives 

 of the northern, eastern, and central tribes, I present the following 

 arrangement, giving the art characteristics in the whole general 

 region where the double-curve is found. This scheme is only a 

 suggestion, as, up to this point, the observations bearing upon all 

 except the strictly northeastern divisions are based upon museum 

 collections. Consequently the interpretations, except that pre- 

 sented under group I, may later have to undergo considerable 

 alteration.
