and other repairs made, at an expense of approximately $3,000. 

 The buildings were also repaired and re-enforced but additional 

 repairs are yet necessary to put everything in prime condition. 

 The sugar house has been used several times during the year 

 by inventors for experiments and demonstrations with ma- 

 chinery designed to improve sugar house operations. The ex- 

 periments conducted in the sugar house during the grinding 

 season have been largely directed toward methods of clarifica- 

 tion, which matter will be referred to again under the heading 

 chemical work of the Station. 



Go-operative work. 



The United States Department of Agriculture offered to 

 carry on investigations on insects injurious to sugar cane, in 

 co-operation with the Louisiana Station and we have made ar- 

 rangements with the Bureau of Entomology by which we are 

 to furnish office and laboratory space in one of the buildings 

 at Audubon Park for their representatives to carry on these 

 investigations, and most of the entomological investigations that 

 we had under way that affect sugar interests have been turned 

 over to the federal bureau. Mr. D. L. Van Dine had charge 

 of this work during the greater portion of the year and was 

 assisted by Mr. T. C. Barber. Toward the close of the year 

 Mr. Van Dine was elected entomologist of the Experiment Sta- 

 tion of Porto Rico, and Mr. T. C. Barber has been placed in 

 charge of the work, and Mr. A. Cushman has been assigned as 

 assistant to Mr. Barber. They have been carrying on experi- 

 ments with the sugar cane beetle, the mealy bug and cane borer. 

 It is hoped that the results there will be a material addition 

 to our knoweldge of measures to control these pests. 



CHEMICAL DEPARTMENT. 



The chemical department has given primary attention to 

 research work as provided under the Adams Act of the national 

 government, along the lines outlined to and approved by the 

 National Department of Agriculture. These investigations em- 

 brace a study of the constituents of sugar cane under various 

 field conditions and a study of the composition of the sugar 

 house products. During a portion of the year we had only one 

 2iian on this work, Mr. W. G. Taggart, Dr. Yoder having re-
