 along urging that the avocation chosen should be one 

 which will supply opportunity for permanent occupancy 

 and ever-growing interest in the event of your being 

 some day able to give it your exclusive attention. 

 That is another reason why the games and recreations 

 mentioned a few paragraphs back are not in themselves

It should not be overlooked, however, that the adoption 

 of an out-door recreation such as walking, riding, auto-

 zoology, ornithology, or geology, that will round it out 

 to full proportions. But in such a case the original 

 sport will presently come to take an altogether subor- 

 dinate place in your interests, as your enthusiasm for 

 the investigation of a new bird-note or an unknown 

 blossom or a mysterious ledge of rocks becomes more 

 and more ardent. And these Nature-studies, I may 

 add, have this further advantage, that they furnish 

 the best possible introduction to the study of Nature's 

 highest product, man himself. Zoology may prove 

 the highway to anthropology and sociology; and no 

 fields are more open than these to the investigations of 

 earnest and logical students; none stand more in need 

 of workers who have had such biological training as 

 Nature-studies would give you. 



It may be, however, that your inherent tastes are such 

 that no line of scientific investigation at all appeals to
