During the past year a house has been 
constructed for the superintendent at a 
total cost of $3,739.23, and a well has 
been drilled, a water tank erected and a 
small pumping outfit installed, at a cost 
of $761.81. The cleared land has been 
improved in condition and 773 additional 
trees planted out in connection with the 
experiments hereinafter mentioned. 
A substantial quarantine cage 30x48 
feet, 10 feet high, has been constructed 
on the property by the State Plant Board. 
In this cage will be planted citrus trees 
which it is found advisable to bring in 
from outside the State and here they will 
be grown for at least one year while being 
kept under observation to determine their 
freedom from diseases and insects. 
No specific appropriation for the sup¬ 
port of the Citrus Station was made by 
the last Legislature, but the appropriation 
bill specified that the Citrus Experiment 
Station should be taken care of out of the 
appropriation made for the main station at 
Gainesville. Out of the latter appropria¬ 
tion the Board of Control set aside $5,- 
690.00 for the fiscal year beginning July 
1, 1921, and this constitutes the total re¬ 
sources of the Citrus Station at present, 
with the exception of $364.65 (gross) re¬ 
ceived this year from the sale of fruit. 
EXPERIMENTS 
We are doing as much experimental 
work at the Citrus Station as the amount 
153 
of cleared land and the available funds 
will permit. 
Dr. R. W. Ruprecht, physiological 
chemist of the Gainesville Station, is car¬ 
rying on a study of the physiological 
causes of dieback, using the young 10-acre 
grove for his field experiments. In the 
bearing grove he is also carrying on fer¬ 
tilizer experiments to determine the rela¬ 
tive effects of high and low percentages 
of potash; also a comparison between am¬ 
monia derived from nitrate of lime and 
ammonia derived from nitrate of soda. 
Other fertilizer experiments, involving the 
use of phosphoric acid, are being carried 
on in commercial groves near at hand. 
A modest experiment in comparing 
rough lemon, sour orange and grapefruit 
stocks has also been started. In this ex¬ 
periment nine varieties of grapefruit and 
three varieties of orange, each on rough 
lemon, sour orange and grapefruit stocks, 
have been planted. The effect of the stock 
on these varieties, under these particular 
soil conditions, will be noted and the varie¬ 
ties in this planting will also be useful as a 
source of material for instructional and 
experimental purposes. This experiment 
is not as comprehensive as it should be and 
we should perhaps explain that it would 
probably not have been started at all were 
it not for the fact that we had most of 
these trees at Gainesville, where they had 
been used in scab-control experiments un¬ 
der nursery conditions, and we did not 
wish to waste them.
