The changes on the staff at the Louisiana stations during the year 

 inchided the appointments of H. Morris to succeed T. C. Paulsen as 

 animal pathologist, and of S. G. Chiquelin as assistant director of the 

 sugar station to succeed H, P. Agee, who resigned to become assistant 

 director of the Hawaiian Sugar Planters' Station. R. G. Tillery, 

 assistant chemist, left the station to go into commercial work, and 

 W. E. Cross was elected to the jDosition of research chemist in charge 

 of Adams fund work. G. Tiebout was given charge of a truck farm 

 for the college of agriculture, affording facilities for some experi- 

 mental work. In this connection an irrigation plant with a 12-horse- 

 power gasoline engine and a pumping capacity of 300 to 1:00 gallons 

 per minute has been installed. 



At the station at Baton Rouge the facilities for work in the depart- 

 ment of plant pathology Avere enlarged and considerable new equip- 

 ment was acquired. The dairy was also enlarged and a concrete silo 

 10 feet in diameter and 40 feet high was constructed. The State 

 appropriations for the year ended June 30, 1911, were $17,000 for 

 ihe sugar, State, and North Louisiana stations and $7,500 for the 

 rice station at Crowley. 



Although some interruption was caused by changes on the staff, 

 the work of the stations made good progress during the year. Under 

 the Adams fund, work on the cottonseed-meal project was continued 

 with pigs, guinea pigs, and rabbits fed with differently treated meal 

 and seed to determine the effect of the different treatments on the 

 toxicity of the products. Salts of phosphoric acid were also used in 

 the feeding experiments, and studies were made of the possible con- 

 nection of fungi such as the boll rots Avith the degi'ee of toxicity. The 

 work on the anthrax project was largely' confined to studying the role 

 of certain birds and insects in the spread of the disease. Cerebro- 

 spinal meningitis was studied by testing the effects of feeding the 

 common molds to horses, rabbits, and guinea pigs. Owing to lack of 

 material, work on the " foot evil " of the horse was held in abeyance. 



In plant pathology the bean-anthracnose project was continued by 

 a further study of the means of prevention, and considerable time 

 was devoted to the further study of cotton wilt and the cotton-boll
