The necessity for independence requires Eskimo populations 

 to utilize their adaptability inwinter. Even the limited human physi- 

 ological adaptation is important in the natural economy of arctic life, 

 and it is interesting to see how this adaptation is used by the Eskimo 

 children for enjoyment of their environment. If it were considered 

 worthwhile we could doubtless dispense with some of the expensive 

 protection from cold that complicates living and restricts our ex- 

 perience. Whether or not physiological adaptation to cold is economi- 

 cal, I hope that some people will continue to practice ways leading to 

 adaptation so that by their reactions we can gain insight into the in- 

 teresting physiological components that appear in human adaptation 

 to cold.
