CLASSIFICATION OF PEARS. 
It is a matter of considerable importance to discover a classification of this fruit, which 
shall furnish constant and distinctive marks. The most superficial observer will not fail 
in recognizing differences between many varieties ; there are others, however, where the 
resemblances are so close that the practical eye fails to discover those differences which 
relieve from doubt and uncertainty. Characters in natural history have degrees of value. 
Color, in some instances, is of the greatest importance ; in others, of no consequence at 
all ; in others still, it is of more or less value, being itself graduated in this respect by its 
constancy. In apples, whose colors are variegated, there seems to be a greater constancy 
than in pears. It perhaps arises from a greater variety in the colors of apples, and in their 
remarkable brightness and depth ; but in pears colorings are mellowed off in a softness which 
is rarely seen in apples. It is difficult to express in terms, the real tint which constitutes 
the main differences in two or more allied varieties. Color, therefore, in pears, though 
important, is less useful as a distinctive mark, than in apples. 
Another important character is obtained by a comparison of the proportion of parts. 
Form is another character which retains sufficient constancy to be employed as a cha¬ 
racteristic. From the foregoing considerations, and others which might be stated were it 
necessary, I propose to make a new classification of varieties of pears, otherwise it will be 
impossible to describe them so as to enable one to recognize them. The season of ripening, 
as it proves a useful fact, will be employed in forming the first division ; at the same time 
it is evident (hat in natural history it is not a basis of any importance. As we find this fruit 
ripening in summer, autumn, and winter, w T e have the three divisions, Summer, Autumn, 
and Winter pears. The disadvantage of this division is, that we have many betweens, 
which it is difficult to locate. Still there are so many advantages in retaining this primary 
division, that I would by no means reject it.
