No. 4.] TOBACCO GROWING. 19 



variety of seed, no special fertilizer or method of growing 

 will give a light-colon >d leaf on a loam or clay soil. 



On the other hand, very dark colors cannot be produced 

 on light, sandy land, except, perhaps, by using animal fer- 

 tilizers, rich in nitrogen, and in quantity large enough to 

 spoil the texture, burn or taste of the leaf. 



Our best tobacco soils are too light for staple farm crops, 

 but heavily manured, make excellent garden-truck farms for 

 quick-growing spring vegetables. They rarely have over 

 five per cent of clay in them. 



On the other hand, the main crop of Pennsylvania tobacco 

 is grown on limestone soil, which may contain thirty per 

 cent or more of clay. Hence the Pennsylvania wrapper is, 

 on (he average, much darker than the Connecticut valley 

 wrapper. But if the fashion changes, so that dark wrap- 

 pers become popular again, our lightest tobacco lands must 

 be abandoned and the heavier "meadow" land taken up. 



The following table, taken from Professor Whitney's 

 Bulletin No. 11, on the tobacco soils of the United Stales, 

 page 18, gives averages of mechanical analyses of various 

 types of soils on which wrappers, tillers and binders are 

 grown : —
