DISEASES. 



WE must commence with the most tiresome, if 

 not the most fatal, of rose maladies, the white 

 mildew, which, alas ! our favourite autumnal 

 roses too often show in autumn, is most difficult 

 to arrest: it does not kill roses, but it destroys 

 the beauty of the leaves and weakens the tree. 

 Flowers of sulphur sprinkled on the leaves 

 and shoots in the evening when they are moist 

 with dew, and washed off with the syringe 

 the following morning about eight o'clock, will 

 arrest it sometimes. If the weather be hot and 

 the sulphur be suffered to remain on the leaves 

 all the day following, mischief often occurs and 

 the leaves burn* If the weather be cloudy, it 

 may remain on the leaves for twenty-four hours ; 

 in all cases syringe the leaves and shoots abun- 

 dantly with pure water to wash it off. 



The Rev. W. Radclyffe recommends ' 2 oz. of blue 

 vitriol' dissolved in hot water, and then mixed 

 with four gallons of cold soft water ; the leaves 

 sprinkled with it night and morning. 



In some soils, a species of red fungus attaches 

 itself to the bark in bright orange-red blotches.
