CONNECTICUT HAVANA TOBACCO. 



On the theory that a change of environment causes variation, Cuban tobacco grown from 

 seed in Connecticut should show wide diversity. A carefully controlled test, however, 

 convinces Mr. Hayes that the supposed variation does not appear, except as it 

 may be the outcome of the mechanical and germinal mixture of characters. When the 

 seeds from a single Cuban plant were sown in Connecticut, the row cultures had a very 

 uniform growth, and the number of leaves was comparatively constant. (Figure 17.)
