The currants were included in the spraying given the entire plantation, 

 after the fall of the leaves in the autumn of 1892. 



A spray with Bordeaux mixture was given them on April 1-3, 1898. They 

 received a second spray on April 18, using 4 lbs. copper sulphate, 3 lbs. 

 lime, and 2 oz. Paris green, in 82 gals, water. 



Rain having intervened, a reapplication of the same was given on 

 April 24 to 25. 



On May 8-9 another spray was given, using 3 lbs. copper sulphate, 1^ 

 lbs. lime, and 2 oz. Paris green, in 32 gals, water. 



The currant worm having put in an appearance, a spray of 2 oz. potas- 

 sium sulphide (liver of sulphur), and one oz. Paris green, in ten gals, 

 water, was applied on June 2. 



This was repeated on June 21, using 3 oz. potassium sulphide instead of 

 two. Rain having intervened, the same was reapplied June 24. 



This preparation was again applied on July 6, omitting the Paris green; 

 and yet again for the last time, on July 22. 



These sprayings have, apparently, had the effect not only to hold the 

 currant worm in subjection, but also to prevent the attacks of the fungus, 

 which has so generally ruined the foliage early in August, since, under 

 this treatment (which was also applied to the gooseberry), there has been 

 no loss of the foliage of either, down to the time of this writing (Oct. 1), 

 while the plants generally have made satisfactory growth. 



It may also be stated, as a possible result of these repeated sprayings, 

 that few indications are visible of the attacks of the twig borer; the infer- 

 ence being, either that the liver of sulphur is repulsive to the moth or, 

 otherwise, that the Paris green may have proved fatal to the larvae when 

 making their first meal upon the recently sprayed twigs.
