management of the dairy, but he learns the underlying principles 

 of operations and processes as well. 



It is not intended to make us men of science, but rather to 

 give a training to enable us to make use of the results obtained 

 by scientific men. 



Tlie physical properties of the soil and their bearing upon its 

 fertility is a subject which in recent years has received much 

 attention from scientific investigators. The knowledge gained 

 from agricultural physics is responsible for the striking results 

 which can be produced by skilful tillage and drainage even 

 without the aid of fertilizers. 



Our scientific knowledge of the structure and physiology of 

 plants is of like recent development. By selection and cross- 

 breeding the present high qualities and productiveness of our 

 staple crops may be directly traced. The improvement of sugar 

 cane, sugar beets, cotton, wheat, fruits, vegetables and flowers 

 are good illustrations. 



In this connection the eminent horticulturist, Luther Bur- 

 bank, should be mentioned. He has given us an inkling of 

 the vast possibilities of plant breeding, which can hardly be esti- 

 mated. The same holds true in animal breeding, the principles 

 of which are but being understood and utilized. 



In the incessant fight which the farmer has to wage against 

 insect pests, and plant diseases, he calls to his aid the sciences 

 of entomology and pathology. Were it not for these branches 

 of science it is doubtful whether today one thriving acre of sugar 

 cane could be found in these islands. It would be interesting 

 to cite examples of work done along these lines. But I com- 

 mend you to visit the several splendidly equipped experiment 

 stations maintained in Honolulu for Hawaii's agriculture. 



Likewise have physiology and sanitation been an inestimable 

 value to the complex art of stock feeding, care and general man- 

 agement. Harnessed to scientific breeding, these sciences more 

 than any other factor, are to be given credit for the wonderful 

 and economic milk yield, prime live stock and the general health- 

 fulness of large herds of farm animals. 



Thanks to veterinary science, tuberculosis is being stamped 

 from our herds, and other dreaded contagious diseases are un- 

 der control. 



Much concern in recent years has been occasioned by the 

 wanton destruction of our great forests. But scientific forestry
