stituents on which depend the burning qualities, 

 the strength and the color. 



The physical qualities of the plant, structure 

 and form, thickness of veins, size, shape and dis- 

 tribution of leaves, are derived from the seed. 



Finally, on the method of cultivation (includ- 

 ing the curing process) depends in part the 

 final color, flavor and aroma ; the type and 

 trade value; that is to say, on successful cul- 

 ture and harvesting and treatment at the right 

 time and in the best way, must depend the 

 grower's hopes of the final value of his crop. 

 The quantity of nicotine, essential oils, etc., on 

 which flavor and strength depend, is regulated 

 to the greatest extent by the time of cutting. 



The nature of the soil is a very important 

 matter in the culture of tobacco, for the color 

 of the cured tobacco leaf depends almost entire- 

 ly on the soil. The light colored leaf is grown 

 on light colored soil and the darker leaf is 

 grown on heavy, dark soil. The best type of soil 

 for the raising of tobacco intended for the cigar 

 trade is a warm, deep, sandy loam which rests 

 on permeable well-drained subsoil. The very 

 light colored yellow tobacco cannot be raised 

 except on light colored, porous soils; and so 

 susceptible is this matter of the coloring of the 

 leaf that it has been noted that the darkening 

 of the soil by a liberal allowance of stable man-
