THE FOETECOMING SITUATION IN AGBI- 

 CULTUBAL WOEK'^ 



The American Association for the Ad- 

 vancement of Science represents the recog- 

 nized and organized sciences. One by one 

 new groups have been added to it, as those 

 groups have won public recognition and 

 have demonstrated tliat they are interested 

 broadly in the enlargement of human 

 knowledge. Half the letters of the alpha- 

 bet are required to designate these groups 

 represented in organized sections, indi- 

 cating the breadth and vitality of our scien- 

 tific inquiry. The last of these sections is 

 agriculture — not the occupation agricul- 

 ture, but the assembly of scientific re- 

 search that deals with the problems of the 

 occupation and of the living resulting from 

 the occupation. We begin the Avork of this 

 section to-day. It means much, I think, 

 for this work that it has now been recog- 

 nized as worthy to occupy a place on the 

 programs with the older and the better 

 standardized groups. I hope that we shall 

 be worthy of the fellowship; and I trvist 

 that the Association itself will gain some- 

 thing by what we and our successors may 

 bring to it in the future. 



There is no field of scientific research 

 that belongs exclusively to agriculture and 

 not to other groups. The peculiarity of 

 the research in this field lies in its associa- 

 tion for the purpose of improving a great 

 industry and of making a particular con- 

 tribution thereby to the national life. The
