now the Earhart Plant Research Laboratory is reviving this interest. This is 

 also the ideal place to study development of the plant in relation to its 

 environment, or experimental Ecology. Men like Clements, Hall, Hiesey, 

 Olmsted, and Weaver have been active in this field. 



Many names of important plant physiologists have not been mentioned, 

 either because they moved in so many different fields or because their signifi- 

 cance lay especially in teaching. Let me mention, however, Barnes, True, 

 Lloyd, Gustafson, Fuller, Robbins, Loomis, and Loehwing. 



Thus, in the short span of 50 years, plant physiology has grown in the 

 United States from a small beginning, when it received most of its inspiration 

 from Europe, to a fully autonomous science, strongly supported because of its 

 significance as a basic science for so many of the applied botanical fields. 

 Being myself from the West Coast, I probably have overstressed the im- 

 portance of contributions from there, but even an impartial evaluation will 

 show that a remarkably high percentage of superior contributions come from 

 there. 



For the future let us look forward to a further period of steady growth of 

 plant physiology, for the sake of gaining a better understanding of the world 

 around us, and to help the applied botanical disciplines in making plants serve 

 us better. To this end we should cooperate to the fullest extent with each 

 other and with our colleagues in the applied fields and obtain further coopera- 

 tion from the sciences which are basic to ours. But perhaps even more than 

 doing more and better research, we should pay much attention to the teaching 

 of plant physiology so that we will see our ranks swelled with eager young 

 colleagues, not only fully trained, but also full of enthusiasm and imagina- 

 tion. To this end our individual efforts are not enough; strong botanical so- 

 cieties are needed for coordination of our efforts.
