For the social and moral welfare of the hu- 

 man race it is necessary that our environ- 

 ment provide means for the satisfaction of 

 the fundamental instincts of man, and in the 

 opinion of many the desire to come into con- 

 tact with Nature and to understand the phe- 

 nomena and facts of Nature about us cannot 

 with safety be neglected in the instruction of 

 the young. Professor Moseley's Trees, Stars, 

 and Birds covers three fields of Nature that 

 have a perennial interest for the human mind 

 and brings to the help of teachers who lack 

 special training in outdoor science the wide 

 knowledge and teaching experience of the 

 author. Since the motto of the World Book 

 Company is " the application of the world's 

 knowledge to the world's needs," editor and 

 publisher have pleasure in offering to the 

 schools a text that promises to be useful in 

 helping to satisfy a need that has its origin 

 deep within the nature of man
