Temperature Observation Work. — A large amount of data 

 has accumulated from this work, and is now being tabulated 

 and studied as to its relation to peach and apple growing. 



Several new lines of work are under consideration in the 

 hope that they may be undertaken in the near future. These 

 center around the general question of soil management and 

 fertilization of apples, peaches and bush fruits. Means of pro- 

 moting the bud hardiness of peach should have some consider- 

 ation, and we could well undertake some further work in 

 pruning.
