126 HORTICULTURE BY IRRIGATION. 



spring. We then have to wait for young trees and sprouts to come for- 

 ward, and this, too, is one reason for the long intervals between crops 

 from this class of trees. 



From the knowledge of these facts, it will not be difficult to under- 

 stand why it is that there is a difference in the resisting power of the 

 bloom of trees in flower at the same time, and all subjected to the same 

 degree of frost. Yet and here is a point likely to be overlooked, and 

 which complicates the matter trees in the same orchard, all in the same 

 stage of forwardness as to blooming, may not be subject to the same degree 

 of cold at the same time. After these spring frosts, it is curious to note 

 single trees, or one side of a tree, or the upper or the lower branches, or 

 even a single branch, having a full crop, while elsewhere there is but 

 little fruit. I am sorry not to be able to give you more exact information, 

 but I believe that all I really know about the matter is given above. 



Yours truly, 



T. H. HOSKINS.
