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

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

on permeable well-drained subsoil. The very

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
