The complex set of conditions comprehended within the term 
climate does not enable us to assign relationship between the amount 
of crop and any one factor; hence sums of temperature required for 
the development of any given crop cannot have uniformity under 
varied conditions as regarding moisture and probably sunlight. For 
the purpose of illustrating this point, some Philadelphia Extra Early 
Peas have been planted at intervals during the season, with the fol- 
lowing result: 
No. 
Planted. 
Vegetated. 
First bloom. 
First edible. 
First ripe.
