DESCRIBING GRAPES )7 



characteristics of any variety, considered from 

 the point of view of the grape grower. In 

 some sections, more especially in California 

 and in Europe, the insect known as the phyl- 

 loxera is a perennial menace to the grape- 

 growing industry, and in such localities one 

 of the most critical qualities which a vine can 

 have is immunity from the ravages of this 

 insect. Different species, and even different 

 varieties of the same species, differ greatly in 

 this respect, and these degrees of immunity 

 or susceptibility are particularly worthy of 

 note. 



The foliage should be described as to vigor 

 and abundance. The individual leaves should 

 be described with respect to size, form, thick- 

 ness, and surface. The surface is often downy 

 or tomentose in various degrees, especially on 

 the lower sides of the leaves. Unfortunately 

 the description blank for grapes shown in the 

 engraving does not give a special caption to 

 the foliage nor to the leaf. It also omits any 

 printed suggestion of general notes. In these 

 respects it is seriously inadequate.
