THE ECONOMIC STATUS OF INSECTS AS A CLASS. 569 



of this dominant type is one of the most interesting fields of study open 

 to the biologist to-day. It would seem as if, in man's efforts to make 

 the face of the earth his own, all the complicated elements of life were 

 arrayed against him, and the great and ultimate result of the labor of 

 the biologist in his study of the relations of the different forms of life 

 and the laws which govern their development will be to bring about 

 the absolute control of all other life by man. Thus it is not only the 

 economic worker who looks for immediate results of a practical kind 

 from his labor — the scientific agriculturist, the horticulturist, the eco- 

 nomic zoologist, the medical bacteriologist — who should command the 

 respect of even the practical-minded man, but the biologist in whatever 

 field, however restricted it may be, whether he is working toward the 

 understanding of broad principles and general laws, or whether in 

 some narrow corner of research he is accumulating material which will 

 help ultimately to lead to wider understandings — all are working help- 

 fully and practically toward the perfect well-being of the human race.
