TOBACCO

the shade-grown Cuban tobacco is also sold as high-priced 

 cigar wrappers. Cuban tobacco grown without shade 

 is chiefly employed for cigar fillers ; that is, for the body 

 of cigars. In the United States it is grown chiefly in 

 Connecticut and near the Gulf Coast. 



The dark, heavy tobaccos of southern Virginia and of 

 Tennessee, — for example, the varieties Blue Pryor and 

 Orinoco, — belong chiefly to the ^ 



chewing or plug and to the export 

 types. The greater part of the 

 bright tobacco of North Carolina 

 and of the light-colored tobaccos 

 of Virginia and Maryland are 

 employed for smoking. 



The .White Burley, grown in 

 Kentucky, is chiefly used for 

 chewing tobacco, but also for 

 smoking. 



516. Saving seed, and tobacco 

 breeding. ^ The large, conspicu- 

 ous flowers (Fig. 214) of tobacco 

 are borne in clusters. The 

 flowers are either self-pollinated 

 or cross-polhnated. Experiments 

 have demonstrated that by in- 

 closing the flower buds under 

 paper bags so as to prevent cross- 

 polhnation, the plants from seed 

 thus produced are more uniform, productive, and vigorous 

 than when cross-pollination is permitted. Any variety 

 of tobacco can be improved by careful selection of the
