demonstrating specimens of citrus can¬ 
ker supplied him by Director Rolfs, teach¬ 
ing growers to recognize the disease and 
distributing much information about cit¬ 
rus canker and its control. 
The Board of County Commissioners 
of Osceola also paid the expenses of the 
county agent, Mr. Evans, to visit the same 
territory. On Mr. Evans' return he called 
the growers together and aroused their 
interest and then began on inspection 
work in groves where nursery stock had 
been purchased from infected territory, 
inspecting practically all young citrus 
trees in the countv that had come from 
j 
quarantined nurseries. 
Legally, it is not possible to apply the 
funds of the Demonstration Work to cit¬ 
rus canker, consequently no money could 
be directly used for that purpose, but be¬ 
cause of the urgency of the situation, it 
was deemed advisable to recommend that 
the agents spend as much time as could be 
spared on this kind of work, owing to the 
peculiar circumstances. 
This constitutes the most important 
work conducted in citrus from the stand¬ 
point of the Demonstration agents to date, 
although much time is taken up by other 
agents who look to the Experiment Sta¬ 
tion workers for help when necessary. 
The work of the demonstration agent 
is to make practical demonstrations of the 
beneficial practices and principles that 
have passed through the experimental 
state and not to undertake new experi¬ 
ments or assume the management or di¬ 
rection of groves, farms, or truck crops. 
It is difficult, however, to undertake work 
of this character without going slightly 
out of the particular sphere for which it 
was intended. 
For instance, the demonstration agents 
of Florida this year have inoculated up¬ 
ward of 25,000 hogs. A much smaller 
number would have been sufficient to 
demonstrate the use of serum, but as these 
agents are directed to assist the farmer 
in every legitimate way, it seemed ad¬ 
visable to do this work on such big scales, 
thereby conducting a thorough campaign 
against hog cholera. Hereafter, the duty 
of the demonstration will be stressed on 
this point and the agent will not be re¬ 
quired to spend as much time as this has 
taken in the past year because of other 
pressing duties close at hand. 
CO-OPERATIVE SPRAYING DEMONSTRATIONS 
We propose to conduct practical dem¬ 
onstrations in spraying for the systematic 
control of whiteffies, scale, rust mites and 
such pests as may interfere with the thrift 
of trees or injure the fruit for market. 
The plan for carrying out demonstrations 
is to enter into definite co-operative ar¬ 
rangements with such growers as will 
carry out the different spraying opera¬ 
tions at the proper time and with the 
proper solutions on a par or all their 
groves, as they see fit, for the purpose of 
controlling or holding in check such pests 
as may be present. These demonstrations 
are to be arranged, so far as possible, by 
the county agent, who will receive direct 
help and personal attention from the Flor¬ 
ida Experiment Station through the spe¬ 
cial department working on such insects 
and diseases. As far as practical, such 
demonstrations shall be located near pub¬ 
lic roads, where they will be readily ac-
