 Magazines " a suggestion was made (to which I have not

 in moderate quantity, would prove a sure preventive. I 

 know of no case where this has been tried. The sulphur 

 would prove valuable as a fertilizer; and possibly a very

 yard. So far as the sulphuric acid, which the vine im- 

 bibes, tends to promote vigor, and prevent the enfeebled 

 condition and viscid secretion of the leaves, it should be 

 applied like ashes, to give constitution and tone, which 

 will enable the vine itself to resist the disease. With this 

 design in view, it is well to make trial of sulphur as a 

 dressing; but, when we 'have the direct "intent to kill," 

 we must make more direct application. 



In forcing - houses or graperies that have hot -water 

 pipes or flues, it is a very simple and effectual plan to dust 

 the flower of sulphur upon the pipes or flue. The fumes 

 of sulphur pervade every part of the house ; and, in such 

 an atmosphere, the fungus cannot live. Care must be
