tion, and a Biological Farm would form an ideal biological center. 

 Each would help and be helped by the other two. 



Cooperation. There should undoubtedly be several biological 

 farms in the country. The larger universities might well have 

 their own farms, and thus very extensive and effective coopera- 

 tive work be carried on. 



Use to Science. The farm would enable us to approach all the 

 fundamental problems of life from the two sides of observation 

 and experiment on living organisms. It would furnish material 

 for study with precise records, and make it possible to keep up 

 continuity in the experimental study of heredity and variation. 



Practical Utility. The utility of such work is seen when we 

 reflect on the practical results already realized in the multiplica- 

 tion and improvement of domestic species of animals and plants 

 through cross-breeding, hybridisation and selection. We have 

 very meager and uncertain knowledge of the laws of heredity 

 and variation laws which underlie all progress of the race.
