and smoking tobaccos, cigarettes, and for export purposes. This 

 variety is adapted to sandy soils, underlaid by a red or yellow clay 

 subsoil. The deeper the sand the brighter the tobacco produced, and 

 the nearer the surface the subsoil comes the more inclined the to- 

 bacco is to darken in color. The leaves are light and spongy, of 

 rather thick texture, set close together on the stem, with an erect 

 habit of growth, but drooping at the ends, the tops often touching 

 the ground. This variety is a modified type of the native Maryland 

 and Virginia tobaccos. Grown in North Carolina, Maryland, Vir- 

 ginia, and South Carolina. 



Maryland Smoking, Used for manufacturing and export pur- 

 poses. Adapted to clay loam and sandy soil. The leaves are thick 

 and coarse in texture, but are light and chaffy when cured. They 

 have a semi-erect habit of growth, drooping at the tips, varying in 

 length from 20 to 36 inches and in width from 10 to 26 inches. The 

 plants bear from 10 to 18 leaves and reach an average height of 

 about 4 feet. This variety was discovered in Maryland when the first 

 settlers explored that region. It is mostly exported to France, Ger- 

 many, and Holland. Grown in Maryland, Virginia, and Pennsyl- 

 vania. From the Maryland tobacco manjr of the important native 

 varieties have been developed by growing in different tobacco-grow- 

 ing sections and by continued selection of seed for a particular type 

 of tobacco. 



PLUG TOBACCOS. 



White Burley. Used for plug fillers and wrappers for smoking 

 and for the manufacture of cigarettes. Adapted to well-drained, 

 deep red, clay loam soil. In Kentucky such soils are fairly rich in 

 lime and produce good crops of corn, wheat, hemp, and grass, but 

 they deteriorate rapidly unless the fertility is maintained by the use 

 of fertilizers and proper methods of cultivation. The leaves are long 

 and broad and have a white appearance in the field. They have a 

 horizontal habit of growth, the tips hanging down and often touch- 

 ing the ground. They vary in length from 28 to 36 inches and in 

 width from 16 to 24 inches. The plants bear from 10 to 18 leaves 

 and reach an average height of about 4 feet in the field. This vari- 

 ety is a selection from the original Burley, the peculiar white, trans- 

 lucent appearance of the original parent plant having attracted the 

 attention of the growers. Seed saved from this plant produced a 

 large number of plants the following season, and in time a large 

 and important industry was developed from this beginning. The 

 Red Burley and dark tobaccos of southern and western Kentucky 

 and Tennessee are heavy tobaccos, nearly related to the White Bur- 

 ley, but on account of their peculiar characteristics are largely ex- 

 ported. Grown in Kentucky, southern Ohio, Tennessee, and to a 

 limited extent in North Carolina, and Virginia. 



Orinoco and Yellow Mammoth. Used for plug wrappers and 

 fillers and are stemmed for export trade. Adapted to rich, well- 

 drained soils, doing especially well on alluvial soils underlaid with 

 red clay subsoil. The Orinoco variety has short, broad leaves, while 

 the Yellow Mammoth has large leaves, both varieties having a rapid
