THE CLASSIFICATION OF PEARS 173 



2. Colored fruit; such as is marked distinctly 



with red in the sun. 



3. Russeted fruit; such as is distinctly marked 



more or less with russet. 



Following this outline, we may readily ana- 

 lyze any number of varieties into thirty-six 

 groups, and these groups may be further sub- 

 divided by characters of calyx, basin, etc., into 

 many smaller sections if one's convenience 

 seems to be served thereby.

 on a few varieties, as follows : 



I. Round or oblate, 

 (rt) Summer. 

 (^) Autumn. 



1. Green or yellow. 



2. Red. 



3. Russet Merriam.
