TOBACCO

the shade-gro^Mi Cuban tobacco is also sold as high-priced 

 cigar wrappers. Cuban tobacco grown without shade 

 is chieflj^ emploj-ed for cigar fillers ; that is, for the body 

 of cigars. In the United States it is grown chieflj- in 

 Connecticut and near the Gulf Coast. 



The dark, heavy tol^accos of southern '^'irginia and of 

 Temiessee, — for example, the varieties Blue Pryor and 

 Orinoco, — belong chiefly to the 

 chewing or plug and to the export 

 tjT^es. The gTeater part of the 

 bright tobacco of North Carolina 

 and of the light-colored tobaccos 

 of Virginia and jMaryland are 

 emploj'ed for smoking. 



The ^ATiite Burlej^, 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-pollinated. Experiments 

 have demonstrated that by in- 

 closing the flower buds under 

 paper bags so as to prevent cross- 

 pollination, 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
