This lot was boiled very rapidly for about 30 minutes, at the end 

 of which time it was a dark green. There had been a shower and 

 the trees were somewhat damp at the time of application. There 

 was quite a little rain during the following night and while the 

 wash was very apparent on the trees the next day, it showed a 

 little washing from the rain. April 15 the application appeared 

 to be fairly even and showed slight signs of washing. July 13 

 there was comparatively little breeding and the same was true 

 September 26. 



Formula 7 



This wash, composed of 20 pounds of lime and 15 pounds of a 

 specially fine grade of sulfur, known as the amorphous form to 50 

 gallons of water, was prepared by first slaking the lime and allow- 

 ing it to cool, then thinning it to something like whitewash and 

 adding the sulfur. There was some difficulty in mixing in the 

 latter because it lumped rather badly. The preparation was forced 

 through a screen on adding the requisite amount of water before 

 spraying. It was applied to a few appletrees on the south side 

 of the apple orchard of Mr McCoun at Oyster Bay. April 15 it 

 had washed badly except where there was an abundance of scale 

 which aided in keeping it in place. July 1 1 there was a large 

 amount of breeding and it was plainly evident that this preparation 

 was of comparatively slight value. 



Formula 8 



This wash, composed of 25 pounds of lime and 20 pounds of 

 the extra fine amorphous sulfur to 50 gallons of water was prepared 

 in the same way as formula 6, and applied April 1 to a few apple- 

 trees on the south side of Mr McCoun's orchard at Oyster Bay. 

 The results were practically the same as those recorded for formula 

 7. These two experiments indicate plainly that comparatively little 

 dependence can be placed upon the beneficial action of elemental 

 sulfur alone. A certain portion of it at least must be brought into 

 combination with the lime in order to obtain satisfactory results. 



Formula 9 



This wash, composed of 40 pounds of a high grade carefully 

 hydrated magnesian lime known as limoid and 10 gallons (20%) 

 kerosene to 38^2 gallons of water, was prepared as follows : The 

 kerosene was added to the limoid and stirred into a smooth paste. 

 There was a slight excess of kerosene and an additional pound of
