DOSAGE SCHEDULE, 
65 
could be used at that time of the year without injury to the young 
fruit, the writer prepared a schedule based upon this data. 
According to this schedule, trees n feel in circumference 1>\ i's 
feet over the top, from ground to ground, receive I ounce of cyanid 
for each 100 cubic feel of inclosed space. This proport ion is increased 
on smaller trees, \\ bile on trees w hich are larger it is decreased to offset 
the proportionately smaller leakage (pp. 43 14,47 18). [n preparing 
the schedule the writer began with a tree ll Feel in circumference by 
28 feel over the top. The cubic contents of this tree were determined

Fig. 28.— Dosage schedule No. 1. (Original. ) 
and a dosage calculated which would £ive it 1 ounce to each 100 
cubic feet. Trees of other dimensions, both larger and smaller, were 
then considered and their contents determined. In working out the 
dosage for these trees not only were the cubic contents taken into 
consideration, bul also the rate of leakage as compared with that of 
the tree 41 by 28 feet. Trees which were smaller than this first tree 
would have a greater proportionate leakage rate, while the larger 
ones would have less, lu securing the dosage for various tree-. 
those smaller than -1 1 1>\ 28 feel were given sufficient cyanid in 
excess of 1 ounce per 100 cubic feet to offset the increased leakage,
