After using the sulphuric acid solution, a small 

 amount of pure water should be pumped through the 

 sprayer. If this precaution is not neglected no injury is 

 caused to the metal by the acid. 



The acid solution should be mixed in a wooden 

 vessel. 



A solution of potassium sulphide or liver of sulphur 

 half an ounce dissolved in a gallon of water, is also a 

 good fungicide. If a tablespoon full of liquid glue is 

 mixed with each gallon of the solution it adheres much 

 longer to the foliage. If the whites of two eggs are used 

 instead of the glue, the adhesiveness is still greater. If 

 the foliage is not very tender two ounces of the sulphide 

 may be dissolved in three gallons of water. 



Potassium sulphide acts in the same manner on the 



fungus as flowers of sulphur does when dredged over the 



oliage, but its action is quicker, and if the spraying is 



udiciously carried out the foliage is more uniformly 



covered. 



It may be mentioned that the potassium sulphide 

 solution discolours paint. 



Mr. Mawley informs me that out of the many 

 remedies he has tried, a preparation called " Mo-Effic " 

 has proved to be the most successful in combating 

 mildew. 



ROSE RUST (Phragmiduim subcorticatum). 



During certain seasons this pest proves very 

 troublesome, and is partial to hardy hybrid varieties, but 

 no variety has proved to be immune. It is abundant on
