ADDBESS OF THE PRESIDENT OF THE 



ASSOCIATION OF AMERICAN AGSI- 



CULTUBAL COLLEGES AND 



EXPERIMENT STATIONS'^ 



Two great things have occupied the center 

 of attraction and thought in the affairs of this 

 association and the institutions embraced in 

 its membership during the past year. These 

 are the Smith-Lever Extension Act and the 

 changes in the relations of the agricultural 

 colleges with the United States Department of 

 Agriculture. The discussion of administra- 

 tive questions involved in the new develop- 

 ments along both of these lines will consume 

 a large share of the time of this convention. 

 It is my purpose at the present hour to con- 

 sider briefly some of the broader relations of 

 these matters to the future development of the 

 land-grant colleges and the Department of 

 Agriculture. 



The Extension Act has rounded out the 

 Eederal legislation providing for the endow- 

 ment along agricultural lines of the institu- 

 tions whose establishment was made possible 

 by the land-grant act of 1862, not so much by 

 liberal grants of money for extension work as 

 by recognition of such work as a legitimate 

 and necessary function of these colleges which 

 ought to be performed throughout the nation. 

 The chief importance of the new policy of 

 the Department of Agriculture in its relations 

 with these colleges is the recognition that this 

 national institution, founded also in 1862 pri- 

 marily for research and instruction in agri- 

 culture, is really a part of our national system 

 of agricultural education, represented in the 

 states by the land-grant colleges, and that 

 therefore it should work not alongside of them 

 but in close interlocking alliance with them. 



The enlargement of the functions of both 

 the colleges and the department due to the 



1 Eead at the convention at Waabington, D. C, 

 November 11, 1914.
