Substantial progress. 

 An investigation of the factors affecting the distribution, adhesion, economy of appli- 

 cation and insecticidal efficiency of arsenical insecticides with particular reference 

 to arsenate of lead in its various forms. 



In a general way results so far show that there is apparently a considerable 



shedding of fruit on spraj'-ed trees due to arsenical effect and not to any insect 



injury. Further work will be done along this line and it is believed that it will 



develop something of material value for the consideration of orchard sprayers
