STUDIES IN INDIAN TOBACCOS. 



influence, the width of the leaf is not dependent on the length. 

 The Indian types of tobacco, with their great diversity of leaf 

 shape, illustrate this point well. In countries with a high level of 

 agriculture, economic considerations have eliminated all varieties 

 except those possessing a certain type of leaf, a broad leaf with a 

 large surface. In India, on the other hand, where the conditions

 desired for certain purposes, the cultivation of forms with very 

 narrow leaves has persisted. Type 9 (Plates I and XVIII) is a 

 very good example of a long narrow leaf and in Types 16 and 

 35 we have two leaves similar in length (average length, 42.9 

 cm. and 46.6 cm. respectively) with a very great difference in the
