AcKNOWLiEDGMENT. 



In conclusion I wish to acknowledge the hearty and loyal 

 co-operation accorded me by the different members of the 

 Experiment Station staff. I believe that the time which is 

 usually lost through change in any administrative organization 

 will be somewhat decreased through the services thus freely 

 given. Particularly I wish to express my appreciation of the 

 co-operation given me by Dr. William P. Brooks, formerly 

 director of the Station and now consulting agriculturist; Prof. 

 F. W. Morse, formerly acting director; and Dr. J. B. Lindsey, 

 vice-director of the Station. All of these men have spared no 

 pains in placing at my disposal all information needed in prose- 

 cuting, the work.
