184549.] AMERICAN PLANT IN INDIAN SEASONS. 



1. VeraCruz, 1 9 - 1 2 north latitude, which is one of the 

 native districts of the American plant. 



2. Mobile in Alabama, 3012 north latitude. 



3. Natchez in Mississippi, 31 '32 north latitude. 



4. Madras, 13 -4 north latitude.

Rising temperature in America, but diminishing 108 

 temperature in India during the growing season. 



From the foregoing table it will be seen that in America the 

 seed is sown at a comparatively low temperature, which 

 gradually rises as the plant advances to maturity ; whilst in 

 India it is sown at a comparatively high temperature, which 

 gradually falls as the plant matures. In Mississippi, the 

 seed is sown in April at a temperature of 70, which gra- 

 dually rises from month to month until July, when it nearly 

 reaches 82, and the Cotton is nearly ripe. In August the 

 pickings are approaching their maximum, and then the tem- 

 perature is as high as it is in India during the picking sea- 

 son of March. In India on the contrary, the American plant 

 has to contend with a diminishing temperature instead of a 

 rising one during the growing season. Here the seed is 

 sown in October at a temperature of 82, which gradually 

 diminishes as the plant approaches to maturity, and when the 

 Cotton is most in need of heat and light. Thus at the 

 outset of life, the young plant is stimulated by strong 

 light and high temperature, neither of which is sustain- 

 ed through the growing season ; and in January, when:
