 therefore, be left to mature before digging. All early 

 varieties have a more or less marked tendency to

The Late varieties are those which do not come to 

 maturity until autumn ; the later kinds often continue 

 to grow until cut down by frost. 



Division by Shape. 



Another division is that of shape, the sections being 



Round. 



Kidney. 



Oval.

Kidney potatoes include many popular varieties. 

 One of their worst features is their aptitude to second

 kidney shape and become hour-glass shaped ; the
