Louisiana — Circular No. 13. 



Tjnited States Department of Agriculture. The results obtained 

 in these experiments were most gratifying, and they thoroughly 

 demonstrated the efficiency of the cultural methods when prop- 

 erly applied. Copies of these two circulars are before you.* 



EXHIBITS AT STATE AND PARISH FAIRS. 



At the State Fair at Shreveport, held November 17 to 28, 

 1906, the Commission installed an exhibit illustrating the princi- 

 pal injurious insects of the State and the measures to be used 

 in preventing damage by them or in controlling them. The 

 exhibit occupied 800 squafe feet of floor space and consisted of 

 about 50 large photographs, glass cases of insects, spray pumps, 

 cotton plants taken from our experimental fields in the boll weevil 

 infested section, etc. A model of a small farm, illustrating the 

 pasture rotation method of eradicating the cattle tick, attracted 

 much attention, as did also the exhibit of live ticks engaged in 

 €gg-laying. Bulletins and other literature, contributed both 

 by the Commission and the United States Department of Agri- 

 culture, were distributed to all farmers who desired them. Regis- 

 ters were kept in the exhibit space, where the visiting farmers 

 and fruit growers registered, their names afterwards being 

 placed on the permanent mailing list of the Commission. A table 

 devoted to implements used in modern methods of bee-keeping 

 also attracted much attention. 



Besides the exhibit at the State Fair, somewhat less pre- 

 tentious exhibits were displayed by the Commission at the Parish 

 Fairs of Avoyelles, Webster and Bienville Parishes. One or 

 more assistant entomologists were in charge of these exhibits, 

 explaining methods used in fighting various insects, answering 

 questions, distributing literature, etc. 



It is certain that the good accomplished by these exhibits 

 in educating the farmers in the control of their worst enemies 

 far more than repays the State for the slight expense involved, 

 and I urge that similar exhibits be made this year at as many of 

 the parish fairs as possible. 



♦Circulars 10 and 11 will be sent free to any farmer requestintr them, upon applica 

 tion being nilade to Wilmon Newell, Secretary, Baton Rouge, La.
