Care of Fruit Trees. 623 



Assuming that 35 trees would bear, in five' years from the time 

 they were 13 years of age, 25 bushels of apples per [tiee or five 

 bushels to the tree per year, and assuming that the composition of 

 the apples were as given below, the results reached are :

Phosphoric acid 4.25 14. 128 



Potash 80.95 49. 5 85 



Total value $23 05 



Assuming that in the next five years, the trees would bear 10 

 bushels per year, or 50 bushels per tree in all, and that the leaves 

 had increased in the same ratio as the apples, the following results 

 are reached for the second five years :

Total value $46 10 



Assuming that the trees have reached fair maturity at twenty- 

 three years from setting, and that they produce on an average 15 

 bushels of apples per tree per year for the next ten years, and that 

 the leaves have increased correspondingly, the following results, 

 are reached for the third period of ten years :
