THE BALTIMORE ORIOLE 



317 



ture is composed very largely of long, spring-like horse-hairs, 

 so tightly woven together that even when" the end of a hair 

 waves freely in the air, it is impossible to pull it out. Here 



BALTIMORE ORIOLE AND NEST, 



is genuine weaving, done with hair and fibrous fragments of 

 soft, weathered bark. Let it be remembered at this point 

 that not even the higher apes know how to weave a nest or a 

 roof.
