namely : Nicotiaiia Suaveoleiis, which is a native of Aus- 

 tralia, and is known as "Native Tobacco," and Nicotiana 

 Fragrans, a native of New Caledonia. 



The best known species are as follows : 



(1.) Nicotiana Tabacum, of which there are two varie- 

 ties, viz; Macrophylla (Maryland tobacco) and Angusti- 

 folia (Virginia tobacco). Each of these two varieties is 

 divided into several sub-varieties. 



The Macrophylla is the variety which affords the famous- 

 Cuban and Manilla tobaccos; it has a tine leaf which is> 

 soft and thin, and is much valued in the trade for the tine- 

 qualities of the leaf for binders and wrapi)ers in making 

 cigars. 



Angustifolia is the most commonly cultivated variety itt 

 the United States. 



(2.) Nicotiana Riistica, best known as Hungarian to- 

 bacco, is largely grown in Europe and Asia. There are- 

 also two varieties, a large leaved and a small leaved kind^ 

 both of which yield tobacco of good quality. 



(3.) Nicotiana Persica, a type produced by clim.atic in- 

 tiuences, but long thought to be a distinct type. 



(4.) Nicotiana Crispa. This species is much grown ii> 

 Syria and on the Mediterranean coast. 



(5.) Nicotiana Repanda, a Mexican variety. It has- 

 small leaves, used for imparting the peculiar aroma to 

 Mexican cigars and cigarettes. 



The remaining species, notably Nicotiana, glauca, glii- 

 tinosa, longiHora, nana and sanguinea, are of no commer- 

 cial importance, being of interest only to the botanist and 

 horticulturist. 



III. Climatic Conditions. 



Of the many conditions which affect the quality of to- 

 bacco, the most important is climate ; other conditions may 

 be, in a measure, modified, but very little can be done with 

 regard to climate. The most rational mode of overcoming
