the statement that they are about one size 
smaller. In figuring up 42 cars of or¬ 
anges for the season 1913-1914, it was 
found that the percentage of difference of 
russet and bright fruit in the same car 
ranged from 4 to 16 per cent. Several 
instances are known where fruit was as 
much as 25 per cent. Unfortunately the 
figures obtained from commercial packs 
are not reliable since the grading is not 
done solely on russets and brights. Every 
orange that is misshapen or that has other 
blemishes, regardless of what they may be, 
are usually placed in the third grade. 
Since it is a fact that there is less than 
10 per cent of first grade fruit shipped 
from this State, something should be done 
to raise the grade. Since the prices for 
bright and first grade fruit are usually 
better than for other grades of fruit, it 
makes it more necessary that the citrus 
growers should do something to reap the 
best prices for their product. If it is con¬ 
sidered that first grade fruit is about one 
size larger than other grades and also that 
there is a strong probability that bright 
fruit has better shipping qualities than 
russet fruit, it is imperative that all rea¬ 
sonable methods should be applied to 
make the industry reap the greatest finan¬ 
cial rewards. 
In order to give specific and concrete 
cases to show what can be done the rec¬ 
ords of several groves which have been 
sprayed are here given. 
Grove A: This grove in 1913-14 had 
no blues. It was not sprayed at all dur¬ 
ing that year. This year he expended at 
the rate of 9 cents a box which, by the 
way, is the most expensive spraying I 
have ever known. As a result his pine¬ 
apple oranges graded 60 per cent blue, 35 
per cent red, and 5 per cent yellow. The 
grapefruit graded 30 per cent blue, 67 per 
cent red, and 3 per cent yellow. 
Grove B: This consists of 65 acres of 
grapefruit, the trees of which have a bear¬ 
ing capacity of about 8 boxes. In 1914 10 
cars graded 2 7-10 per cent first, 15 3-4 
per cent seconds, 50 1-2 per cent thirds, 
and 31 1-2 per cent fourth. This grove 
was sprayed under the direction of this 
office in 1915 and the methods will be 
considered in another paper on this pro¬ 
gram. This year, out of a total of 13 cars, 
there was 41 2-10 per cent first, 50 1-10 
per cent second, 8 per cent third and Jr 10 
of 1 per cent fourth. On trees located in 
the middle of the grove left unsprayed 
throughout the year a car graded no firsts, 
3 1-3 per cent seconds, 90 2-3 per cent 
third and 6 per cent plain. To produce 
this difference it cost about 6 cents a box. 
Grove C: This grove was sprayed by 
this office. No records for the grades for 
last year are available. This year it was 
sprayed on the 30th and 31st of July with 
a combination of 1 per cent of oil and 
soda-sulphur solution (regular formula) 
1-50. This fruit was purchased by one 
of the dealers in Orlando, for which he 
paid the highest price for any -fruit that 
had come to his packing house during the 
entire year, and this packer said that this 
was the finest fruit he had packed this 
season. It graded about 95 per cent 
bright. If this spraying had been done 
about three weeks sooner much better re¬ 
sults would have followed. 
It is also well known that spraying will 
increase the yield from year to year, and
