bug. For the latter, sprinkle lime on and around 
the plants. It may also have some effect upon 
the cutworm, although it is ordinarily necessary 
to poison this plague with a mixture of bran, 
Paris green, and molasses, or some other liquid to 
make a pasty mass. 
The diseases of vines are practically all of 
fungous origin, although the parasites work in 
different ways. Occasionally the attack of a 
fungous disease resembles the work of an insect, 
but upon close observation the true nature of 
the disease can usually be discovered according 
to the class to which it belongs. Of these classes 
there are four that the grower of vines may 
encounter. 
Rust usually starts as little whitish-yellow 
spots on the leaves, which, if not taken in hand 
at once, grow larger and darker. Eventually 
the plant succumbs to the effect produced by the 
growing fungus making its way through and 
feeding upon the tissues beneath where the 
spots appear. The leaves that are first affected 
by this disease should be cut off, and the plant 
sprayed at the first opportunity. Bordeaux 
mixture is the great fungicide and probably the
