THE FUTURE OF AGRICULTURAL 



SCIENCE IN THE AMERICAN 



ASSOCIATION FOR THE 



ADVANCEMENT OF 



SCIENCEi 



It is certainly within the recollection of 

 the youngest member of Section O that the 

 attachment of the designation Agricultural 

 at once remoTed the matter under discussion 

 from the scientific field. Agricultural botany, 

 agricultural physics, agricultural chemistry, 

 and the other agrieulturals were simply the 

 reflections of the glories of the pure sciences 

 into the dark, unfathomed caves of everyday 

 living. lifo real botanist would study the 

 corn plant. No real chemist would waste his 

 time on its chemical composition. The phys- 

 ics of the soil was certainly beneath the phys- 

 icist. Such lights in the darkness as Darwin, 

 Liebig and Pasteur (whose great work was 

 done with domesticated plants and animals, 

 soils and industries agricultural in the broad 

 sense) failed to sensitize the blind spots in 

 the minds of the pure scientists of yesterday. 

 To-day this situation no longer exists, not so- 

 much because of any change in the sciences 

 themselves, but more because of the sensiti- 

 zation of the blind spots in the minds of those 

 who devote themselves to scientific study. 



This change has come about largely as the 

 result of the work of the agricultural experi- 

 ment stations. It is true that in the begin- 

 ning much was done by workers in the sta- 

 tions in the name of science that was not 

 scientific, but that has always been true, even 

 more in the history of so-called pure science 

 than in this period of the beginning of agri- 

 cultural science. It is generally true to-day. 

 In the beginnings of agricultural science,
