*¢ In this hasty communication I shall only further mention 
what has been stated to be an effectual remedy in the English 
_graperies, when applied in time, namely, flowers of sulphur, 
either by themselves, or mixed with lime-water. The pounded 
mineral has been scattered over all parts of the vines, both in 
a dry state, and in a state of suspension in water. In the 
former case, it is blown through a machine called a sulphura- 
tor, something in the way of a common bellows; and in the 
latter, it is washed on with the ordinary garden syringe. All the 
best practical observers state that in either way it kills the fun- 
gus, and arrests the disease. The same remedy has long been 
understood and applied by horticulturists to destroy the mil- 
dew on peach trees, as it does, and the disease stops, which fact 
goes a considerable way in proving the fungus to be the cause, 
and not the consequence.”
