" The species most generally cultivated is N. Tabacum. The seeds 

 of N. repa'nda, Bot. Mag., t. 2484, were given to Mr. G. Don, as that 

 of the species from which the small Havannah Cigars are manufactur- 

 ed ; but smokers find little difference in flavour between these and the 

 larger kind. IV. multivalvis, Bot. Reg. t. 105, is cultivated by the In- 

 dians who inhabit the banks of the Columbia, while those of the rocky 

 mountains and of the banks of the Missouri, prepare their tobacco 

 fromiV. quadrivalvis, Bot. Mag. t. 1778, and N. nana, Bot. Reg. t. 883, 

 which are allied to the former. N. rustica is chiefly cultivated in 

 Western Africa (Mr. G. Don), as well as in Egypt, according to Mr. 

 J. Bennet, from specimens brought by Mr. Wilkinson. Mr. D. Don in- 

 forms me that it also affords the tobacco of Salonica (the ancient Thes- 

 saloniea); probably also that ofLatakkia (Laodicea), which is so much 

 esteemed. It is also cultivated in the north of Germany, Russia, and 

 Sweden; according to Mr. Loudon, with N. tabacum, near Utrecht 

 and Guelders ; and a variety of it in Ireland. From Parkinson we 

 learn, that it was the kind preferred by Sir W. Raleigh. 



In taking a view of the climate suited to the cultivation of any of 

 these species, nothing so much excites astonishment as to find a plant, 

 which with rice, sugar, cocoa, coffee, and cotton, attains great perfection 

 in tropical regions, also successfully cultivated in the northern cli- 

 mates of Sweden and Scotland. This is owing to its being a plant re- 

 quiring only a few months to bring it to perfection, and therefore find- 

 ing the summer temperature of many countries suffice for its cultivati- 

 on ; but it is still remarkable to find tobacco cultivated with equal 

 success in Cumana and in Maryland. 



" The cultivation of tobacco in North America for foreign commerce,- 

 is chiefly carried on in Virginia and Maryland, or almost from 35° to 

 40° of northern latitude. The climate of America, as we have seen 

 when treating of the cultivation of tea, p. 113, is like that of China,, 

 subject to great vicissitudes between winter and summer, but the lat- 

 ter only being that with which we have any concern in the cultivation 

 of an annual plant, it is sufficient to mention, that according to the il- 

 lustrious Humboldt, the mean temperature of Williamsbourg in N. 

 lat. 38° 8' is 58°, and of Philadelphia in N. lat. 39° 56' is 54° and the 

 mean temperature of summer in the latter, 73° 94/ The other places 

 which are celebrated for their tobacco, are Havannah, lat. 23° 10', mean 

 temperature of year, 78°. 08 ; of summer, 83°. 3 : Vera Cruz, lat. 19o.1T 

 M. T. 78°. 08 ; and Cum ana, lat. 10o. 27' M. T.81°. 86; S. T. 83°. 7. 

 But as these much exceed the summer temperature of northern places 

 where it is grown, as of Stockholm, 61°. 88; Dublin,*59°. 54; Edin- 

 burgh, 58° 28 ; it will be necessary to inquire, whether there are any 

 peculiarities of climate in the places where tobacco is actually grown.. 

 But here we shall meet with considerable difficulties in as ceo: taming.
