18 EXPERIMENT STATION. [Jan. 



port calls attention to the fact that earlier experiments here 

 showed the lime and sulfur treatment to be the most effective. 

 Later investigation confirms these early results. The report 

 deals briefly with a number of the proprietary mixtures rec- 

 ommended for the destruction of the San Jose scale, but states 

 that none of them has been found equal to the lime and sulfur 

 mixture. The report makes mention of the work on cran- 

 berry insects and the investigation as to the newly imported 

 oriental moth, both of which have been previously referred to. 

 It concludes with brief reference to some of the more destruc- 

 tive insects of the year. 



The report of the veterinarian briefly discusses the nature 

 of the work which his dejiartment has been called upon to do. 

 It will be remembered that this division has been organized 

 only since July. 



The report of the horticulturist makes brief meijtion of the 

 different lines of experimental work in progress, and reports 

 in detail the results of experiments iu mushroom growing. 

 These indicate pure-culture spawn to be much superior to the 

 ordinary commercial spawn, and that there is a wide differ- 

 ence in the characteristics of different varieties as regards 

 productiveness and quality. The results indicate that the 

 possibilities of profit in mushroom culture are by no means 

 as great as is often represented.
