On November 11, 1918, the writer was granted a four months 

 leave, to study the influence of temperature and humidity 

 on the development of the citrus canker organism and the 

 disease caused by it, in the botanical laboratories and green 

 houses of the University of Illinois. 



(2) Some of the Local Experiment Fund has been used to 

 maintain the field laboratory at Loxley, Alabama. Besides a 

 study of citrus canker, observations have been made on the 

 plant diseases peculiar to South Alabama and the farmer 

 advised in preventive and control measures. 



No definite projects have been started but the work under the 

 Local Experiment Fund this past year has been confined to 

 observations of a number of troublesome plant diseases, some 

 of which are new or little known in Alabama. 



Respectfully submitted, 



GEORGE L. PELTIER, 



Plant Pathologist.
