 favourable to the growth of all fungi.' — Cottage Gardener's

Mildew is generated in vineries through a close, damp, 

 chilly atmosphere, combined with an insufficient circulation 

 of air and heat, caused by the temperature being kept too 

 low. The practice of growing a variety of plants in the 

 house with the vines is another and invariable cause of 

 mildew. The plants require continual watering, and a 

 somewhat close atmosphere and low temperature, which 

 is altogether unsuited to the vine. The two cannot be 

 grown together. Mildew often makes its appearance in 

 summer-time, when there happens to be a continuance ot 

 cold, wet weather. At such times it is almost certain to 

 appear, unless a brisk heat, with a dry atmosphere and a 

 free circulation of air, is kept up. I have been able to 

 prevent this disease from making havoc amongst my vines 

 without having recourse to the use of sulphur on the foli- 

 age, stems, and fruit. Where this is resorted to, it necessi- 

 tates the grapes being rinsed in water before they can be 

 sent to table; as a matter of course, the bloom will be 

 injured. To prevent the bloom from being destroyed, 

 therefore, I advise that when mildew makes its appearance, 

 sulphur should be applied to the pipes or flues, as recom- 

 mended in the case of red spider. The same treatment of 

 course will answer for both pests, although the one is an 



insect and the other a fungus. It may be observed that, as
