INDIANA. 137 



Investigations on eradication of weeds and on treatment of grain 

 smuts in elevators were continued. Of six different chemicals used, 

 common salt was found most convenient and effective for the eradica- 

 tion of Canada thistle. It is further found that, under certain con- 

 ditions, white top in timothy nieadows may be controlled by the use 

 of chemical sprays, and that red sorrel and broad plantain are very 

 greatly affected by sodium arsenite as a spray. Tests were made at 

 the station and near Terre Haute of strains of the Stone tomato for 

 canning purposes. Methods of spraying for canteloup rust were 

 tested and a comparison was made of a single spray versus three 

 sprays of arsenate of lead. 



The horticultural department made plantings of catalpa and locusts 

 for fence posts at the station and in different parts of the State. 

 With funds provided by the State, 16 acres of land were purchased 

 for this department, fenced, and partly set in fruit trees as an ex- 

 perimental orchard. An extensive experiment to test sod mulch as 

 compared with clean culture was laid out. The search for valuable 

 native seedling pecans has resulted in the finding of several more 

 valuable varieties. A large amount of demonstration work in orchard 

 improvement and management was carried on in different parts of 

 the State. 



The cooperative work of the station in testing varieties, methods 

 of culture, and fertilizing is very extensive, over 1,000 farmers tak- 

 ing part in such work. The station gave particular attention during 

 the year to the study of unproductive soils and the methods of im- 

 proving them in about fifty different places in the State. Coopera- 

 tion was also carried on with this department in seed examination 

 and the study of grain insects. The extension work, which is now 

 organized on a separate basis, included district farmers' short courses, 

 fair exhibits, agricultural meetings and exhibits, horticultural dem- 

 onstration meetings, and work in connection with an educational 

 train, rural school of agriculture, and young people's contests. An 

 educational train was run in the interests of the dairy industry and 

 2,558 persons heard the lectures given in this connection.
