ing the various crops. Most people do not realize that 
the thirty or forty common vegetables which anyone 
could name in a few minutes were brought here from 
all parts of the earth, and that we can only succeed in 
growing them here by furnishing them with relatively 
the same conditions under which they originated and 
developed. Naturally, coming from many widely dif- 
ferent climates, each crop has its special temperature 
and moisture requirements. We recognize this ten- 
dency by growing them during a time of the year best 
suited to their needs, and by planting them in moist 
or dry locations according to their preferences. Hap- 
pily, the thirty or forty different vegetables divide 
themselves into groups according to the temperature 
and moisture requirements, so that instead of it being 
a problem of remembering thirty or forty different 
cultural methods, we may reduce the number to a very 
few by dividing the vegetables into groups. 
All vegetables may be divided into two general 
groups: ‘‘cold-season’’ and ‘‘warm-season’’ groups. 
The cold-season crops are those which originated in 
temperate climates, and the warm-season crops are 
those which originated in the tropical and subtropical 
regions. 
Planting table. The following table takes into 
account the seasonal requirements of various garden 
crops and also indicates the varieties that should be 
planted at different times. There are other varieties 
which no doubt could well be added to this list, but 
those named can be depended upon in general to give 
satisfactory account of themselvés. By selecting the 
varieties named and planting them as nearly as pos- 
sible at the times mentioned, taking into consideration 
the latitude of the place in which they are grown, the
