The dash (—) placed before the difference in price indicates that 
a lower grade sold for more than the next higher grade. This oc- 
curred several times among the grades of oranges, but not among 
those of grapefruit. The only explanation that can be offered for 
this irregularity is that the lower grades had the sizes desired by 
the trade at the particular time of the sale. 
Table 7 shows the differences in price for the grades of 400 805 
boxes of oranges and 126,193 boxes of grapefruit when these are 
divided into three instead of five grades.

If the difference in price received for the first and third grades be 
added and the sum be divided by the number of months, an average 
difference of 30 cents in price received for the oranges and 72 cents 
for the grapefruit is obtained. In a miscellaneous lot of 5,427 boxes 
of fruit, the first grade averaged 48.8 cents more than did the second 
grade, and the second averaged 8.3 cents more than did the third 
grade. 
Opportunity is seldom presented for comparing the price of 
sprayed and unsprayed fruit from the same grove. Through the 
cooperation of Mr. J. A. Stevens, of De Land, this was done with 
two carloads of grapefruit shipped in 1914 from sprayed and un- 
sprayed trees, that were picked and packed on the same day and 
sold in the same market. The sprayed fruit sold for $1.94 per box; 
the unsprayed fruit for $1.69. These respective prices are disap- 
pointing. It had been anticipated that there would be at least a 
difference of 75 cents instead of 25 cents in favor of the sprayed 
fruit. The net profits due to spraying, however, were sufficient to 
pay one-fourth of the freight charges. Although the difference is 
slight, it is more than four times what it cost to spray the trees. The 
prices of the respective grades of the fruit could not be obtained. 
In a grove about 1 mile distant from the grove previously men- 
tioned 516 and 300 boxes of grapefruit, respectively, were picked from
