A CENTURY OF GEOGRAPHY IN THE UNITED 

 STATES* 



Men and women occupied with the small 

 and special details of a large and complex 

 work are not well situated for understand- 

 ing the scope of the large work to which 

 they contribute. The shop girl in Water- 

 bury who spends her days and years in 

 cutting threads on tiny screws may have 

 very limited knowledge and erroneous 

 opinions about the watch industry. The 

 trained arithmetician who spends his 

 months and years in adjusting triangu- 

 lation or verifying computation does 

 not thereby acquire valuable opinions as 

 to the scope and conduct of a great na- 

 tional survey. In our day many, if not all, 

 branches of human knowledge and activity 

 are widening. As they widen they are spe- 

 cialized. The student of nature, the practi- 

 tioner of medicine or law, the artisan, each is 

 prone to contract the size of his field of ac- 

 tivity and to study more profoundly some 

 small part of the large subject. Even the 

 farms grow smaller and are better cultivated 

 than formerly. Such subdivision of the field 

 of study and activity into special and smaller 

 fields has for a century at least progressed 

 steadily, and the world has gained thereby. 

 Many have become profoundly learned or 

 highly skilled in some small subject. You
