860 Report oF THE HorticulrtuRAL DEPARTMENT OF THE 
A study of the foregoing table suggests the following state- 
ments: 
(1) Weight.—The fruit constitutes the largest weight of the 
products taken from the tree. The total weight of dry matter 
removed is on an average 45.25 pounds for each tree, distributed 
as follows: in the fruit pulp 17 pounds or about 38 per ct. of 
the whole; in the peach stones, about 6.5 pounds or 14.5 per 
ct. of the whole; in the leaves, about 16 pounds or 35.5 per ct. 
of the whole; in the new wood, about 5.5 pounds or 12 per ct. 
The peach stones form about 6 per ct. of the fruit. 
(2) Nitrogen.—The leaves contain the largest amount of nitro- 
gen. The average amount of nitrogen removed from the tree by 
the products is about 0.6 pound, of which there is present in the 
fruit pulp 0.12 pound or 19.8 per ct. of the whole nitrogen; in 
the peach stones, about 0.03 pound or 4 per ct. of the whole 
nitrogen; in the leaves 0,42 pound or 67.7 per ct.; and in the new 
wood, about 0.06 pound or 9 per ct. of the whole nitrogen 
removed. 
(3) Phosphoric acid.—The average amount of phosphoric acid 
contained in the products removed from the tree is 0.15 pound, of 
which 0.06 or 42 per ct. is found in the fruit pulp; .008 pound 
or 5 per ct. in the peach stones; 0.07 pound or 44 per ct. in the 
leaves; and .001 or 9 per ct. in the new wood. 
(4) Potash.—The average amount of potash in the products of 
each tree is 0.6 pound, distributed as follows: In the fruit pulp, 
0.29 pound or 49 per ct.; in the peach stones, .007 pound or 1 
per ct.; in the leaves, 0.27 pound or 45 per ct.; and in the new 
wood, 0.08 pound or 5 per ct. 
(5) LIime.—The total amount of lime in the products taken 
from each tree averages 0.95 pound, 83 per ct. of which is con- 
tained in the Jeaves and 15 per ct. in the wood. 
(6) Magnesia.—The average amount of magnesia in the pro- 
ducts removed from each tree is about 0.38 pound, 81 per ct. of 
which is present in the leaves, 9 per ct. in the fruit pulp and 8 
per ct. in the new wood. 
(7) Relative proportions of constituents.—Taking the total 
quantities of constituents given in Table II as an average, we have 
the following approximate relative proportions of: the different 
constituents, based on 1 pound of nitrogen for comparison:
