may be arrested on particular spots where the sulphur is 
applied, but it will not suffice for the Ozdium, for we have 
seen it push through a thick coating atter the ¢ pplication 
had been repeated fur several days together and we weuld 
more forcibly repeat that the fumes emanatirg from sul- 
phur exposed to a high temperature, are the only ra.ical 
cure that we have yet discovered. 
There are several other sorts of fungi which are seen at 
times in the grapery, but which are not any further de- 
structive than by extending a mouldiness to the ripe fruit, 
or decaying leaves or branches, which may be prevented 
by circulating a free current of air through the house, or 
if that be not practicable, as sometimes happens with late 
crops or the Retarding House, by lighting a slow fire, and 
lifting the top ventilators. This will dry up the muisture, 
and be beneficial to the vines, by assisting them to ripen 
better. These last mentioned fungi may be considered as 
epiphytical, for they feed upon a tendency to decay in the 
y upon which they vegetate ; while the first and dan- 
gerous kinds are strictly parasites, which germinate and 
progress upon the living substance, and destroy the or 
ganization of all parts in their co

The difference being, that when a bunch of grapes is said
