The leaf raised in Connecticut, Pennsylvania, Ohio, Wisconsin, Florida, Massachusetts, and New York State, is generally used for the cigar trade (see the chapters on cigars). Ohio and Florida (Cuban seed) leaf mostly used as cigar fillers; Connecticut and Florida (Sumatran seed), Pennsylvania and New York leaf mostly as wrapper leaf, the inferior leaves being used as fillers. Wisconsin leaf is used principally as cigar binder leaf. The total amount of cigar tobacco raised is roughly about one-fifth of the entire tobacco crop. The southern states produce the bulk of the export dark, heavy leaf. West Kentucky and Tennessee particularly, as well as Virginia, the Carolinas and Maryland, export considerable quantities. This tobacco is fire-cured. For the domestic trade, however, (pipe-smoking, chewing and cigarettes) the tobacco grown in these states is flue-cured, the principal product being of a bright yellow color, characteristic of this region. This "yellow tobacco belt" extends from the coast across to the North Carolina Mountains, through Tennessee and South Carolina, Southern Virginia, Southern Ohio, a few parts of Kentucky, some of Eastern Missouri and Arkansas. The best soils are those which are of a light sandy or sandy clay nature and they need not be deep or rich. In this region the very finest pipe-smoking tobaccos are raised. Whilst the U. S. has not been able to produce a cigar wrapper tobacco equal in quality to the Cuban or Sumatran, in pipe-smoking and cigarette tobaccos she stands without a rival. There are about 100 different varieties of tobacco grown in the U. S., many of these being approximately the same and are synonymous. Subvarieties are easily obtained by crossing. Cross-fertilization easily takes place where different strains are produced in the same locality. On this account when it is desired to keep a variety pure, care must be exerted to see that seed is collected from pure strains. On the other hand, the ease of producing new varieties gives opportunity to the various State Agricultural Experimental Stations to try out new strains for desirable qualities. The enumeration of the differences between the various varieties would be tiresome for the reader, yet it will be well for the user of tobacco to know some of these varieties, their characteristics and other particulars concerning them. These are given here: LEADING VARIETIES OF AMERICAN TOBACCOS BURLEY. The variety known as _White Burley_ has a long broad leaf, whitish in appearance when growing. The points of the leaf hang down towards the ground when growing, often even touching the ground. The leaf is thin in texture, has a mild flavor, low nicotine content and good absorbing qualities. It is one of the most popular tobaccos in the U. S. and is used for pipe-smoking and chewing tobaccos and cigarettes. It cures to a bright yellow brown color.
