108 Experiment Station Report. 



The practical management of these operations was, from 

 the beginning to the present time, under the personal super- 

 vision of Prof. Maynard. 



The application of phosphoric acid and of muriate of pot- 

 ash was repeated the succeeding spring. The new growth 

 of branches and leaves showed a decided improvement both 

 in vigor and color. 



The trees have been cut back for several years, and they 

 have since repeatedly produced healthy fruit.
