FRIENDSHIP OF NATURE

 ating the hues of both cultivated and wild flowers, echoing 

 the songs of birds, and illustrated with exquisite pen pictures 

 of bits of garden, field, and woodland scenery. The author 

 is an intimate of nature. She relishes its beauties with the 

 keenest delight and describes them with a musical flow of 

 language that carries us along from a 'May Day' to a 'Win- 

 ter Mood' in a thoroughly sustained effort." Richmond

INTERPRETATION OF NATURE 



By C. Lloyd Morgan. Cloth, 16mo, $.65 net 

 Mr. Morgan here contrasts the two ways of interpreting 

 nature, the one which explains the world in terms of pur- 

 pose analogous to the purposes of man, and the other which 

 works inward from external mechanism to the human brain. 

 He shows that these two interpretations are really supple- 

 ments of each other.
