TOBACCO CULTURE. 9 



Wisconsin, yet both produce good cigar leaf. The time of 

 harvesting and manner of curing have much to do with fix- 

 ing special types or grades of tobaccos, and even more im- 

 portant is the intelligent cultivation of the plant, and its 

 proper fertilization. 



Bearing in mind that growing crops are perhaps as 

 much dependent on the physical condition as upon chemi 

 cal composition of the soils in which they grow, the texture 

 of the soil may be accepted as possessing great influence on 

 the quality of the tobacco produced thereon. Prof. Whit- 

 ney's investigations showed that soils producing tobaccos 

 of similar type, closely resemble each other in the propor- 

 tions of the different classes of soil particles. Thus it may 

 be well to compare the proportions of sand, silt and clay in 

 the tobacco soils of the two typical "wrapper" States, and 

 in two typical "filler" States. New York and Massachu- 

 setts, and Pennsylvania and Ohio furnish the desired local- 

 ities.

The close resemblance between the physical properties 

 in each of these two groups is apparent. The great dissim- 

 ilarity between the properties of the two groups is equally 

 plain. These facts partly explain the similarity of grade 

 and character between tobaccos of New York and the Con-
