gallons. Applied to one-half the old 

 trees. Young trees omitted. 



These applications were all made very 

 thoroughly with a power spray outfit. 

 The objects of the experiments were: 

 First, to determine the relative efficiency 

 of iron sulphide, copper sulphide and the 

 lime-sulphur solution as a control for 



the mildew; second, to determine the 

 amount of control of the mildew that 

 could be obtained by application made 

 at the same time as those for the codling 

 moth; third, to determine if barium car- 

 bonate could be substituted for arsenate 

 of lead as a control for the codling moth; 

 fourth, to determine what control might
