THE BESULT OF THE LAST TWENTY 



YEARS OF AGRICULTURAL 



RESEARCHi 



I PROPOSE to follow the example of my 

 predecessor of last year, in that the remarks 

 I wish to make to-day have to deal with the 

 history of agriculture. Unlike Mr. Middle- 

 ton, however, whose suiwey of the subject 

 went back almost to prehistoric times, I 

 propose to confine myself to the last quar- 

 ter of a century — a period which covers 

 what I may perhaps be permitted to call 

 the revival of agricultural science. 



Twenty-five years ago institutions con- 

 cerned with the teaching of agriculture or 

 the investigation of agricultural problems 

 were few and far between. I do not pro- 

 pose to waste time in giving an exhaustive 

 list, nor would such a list help me in 

 developing the argument I wish to lay be- 

 fore the section. It will serve my purpose 

 to mention that organized instruction in 

 agriculture and the allied sciences was al- 

 ready at that date being given at the Uni- 

 versity of Edinburgh and at the Royal 

 Agricultural College, whilst, in addition, 

 one or more old endowments at other uni- 

 versities provided courses of lectures from 

 time to time on subjects related to rural 

 economy. Agricultural research had been 

 in progress for fifty years at the Rotham- 

 sted Experimental Station, where the work 

 of Lawes and Gilbert had settled for aU 

 time the fundamental principles of crop 

 production. Investigations of a more prac- 

 tical naturfe had also been commenced by
