LOUISIANA. 115 



The following changes in the staff took place: J. G. Lee, sr., resigned 

 as assistant director of the North Louisiana Experiment Station at 

 Calhoun, and J. B. Garrett, formerly assistant entomologist of the 

 stations, was appointed to the vacancy. K. E. Graham, W. D. Reid, 

 and S. W. Plauche were appointed assistants in chemistry, G. Tie- 

 bout, assistant in horticulture, and E. M. Percy, assistant in mechan- 

 ical engineering in connection with work on sugar-house machinery. 

 1>. F. Hochenedel resigned as assistant chemist to engage in com- 

 mercial work. Since the close of the fiscal year, P. A. Yoder resigned 

 as research chemist and AV. Newell as entomologist, the latter to 

 accept a similar position at the Texas Station. A new greenhouse 

 (PI. V, fig. 2), costing about $6,000, was constructed at the State Sta- 

 tion at Baton Rouge, and a residence for the farm nuinager, at an 

 expense of about $1,500, was built at the Calhoun Station. 



A substation for rice culture was established at Crowley and work 

 was begun during the spring of 1909. This station is conducted in 

 cooperation with this Department. Local parties gave 60 acres of 

 land for the use of the station and subscribed $8,500 for buildings. 

 The legislature authorized its establishment by an act passed July 1, 

 1908, but no appropriation for the purpose was made at that time. 

 F. C. Quereau was called from the University of Tennessee to the 

 position of assistant director in charge of this station. 



The research work carried on with the Adams fund included, 

 among other lines, investigations on a number of plant diseases. 

 Some work was done on rice smut and rice blast, and material for 

 study was secured. The wilt disease of pepper was given a good 

 deal of attention and the life history of the soft rot of cotton was 

 studied. Work on cotton wilt included breeding for resistance, 

 better lint, and earlier and more dwarfed types. EHorts were also 

 put forth to determine why alfalfa is difficult to grow at the station. 

 Limincf was tried and 42 varieties obtained from this Deiiartment 

 were put under test to ascertain their resistance to the unfavorable 

 conditions. 



Observations made on cerebro-spinal meningitis in horses were 

 summarized and published as a preliminary report. Work on anthrax 

 was concentrated on the production of superiuuuunized animals for 

 the purpose of obtaining serum that can be used in hastening the 

 development of immunity from the disease. 



Progress was made in the study of the nonsugars of sugar cane, 

 and new methods considered thoroughly accurate were worked out 

 for determining the amount of certain organic acids in the cane. 

 More relial)le methods than those previously in use were also devised 

 for detei-mining formaldehyde in sugar products. The results se- 

 cured pointed to the possibility of formaldehyde being a normal con- 

 stituent of cane juice, and it was observed that at the temperature 

 of evaporation of the juice formaUlehyde is formed.
