613. HEMP, ( Cannalis Sativa,) is a well known plant cul 

 tivated, like the last, for the sake of its fibre, employed in the 

 making of ropes, and coarse fabrics. It is probably a native of 

 India, .but it is now extensively cultivated in Russia, as well as 

 in the United States, in Germany, and in other parts of Europe, 

 in Arabia, Africa, (fee. It is of the same family as the Hop and 

 Nettle, the fibres of both of which genera have been used for 

 the same purpose. According to Prof. Gray, Hemp has become 

 naturalized as a wild plant in this country. 



The Indian Hemp (C. Indica,) (which is the same species (Pereira,) 

 as the above,) is well known as affording a resinous exudation, which 

 is used in various forms, to produce a species of intoxication, among a 

 large portion of the human race. In hot climates, the fibre degenerates 

 in quality, while the narcotic ingredients increase in quantity and in ap 

 parent strength. &quot; This is another of the many interesting facts now- 

 known, which show the influence of climate in modifying the chemical 

 changes that take place in the interior of plants, and the nature and pro 

 portions of the several substances which are produced by these changes.&quot; 

 (Johnston in Blackwood s Magazine, Vol. xxxvii. No. 5, p. 617.) This 

 plant is employed to produce a naicotic effect by probably not less than 

 two or three hundred millions of the human race in Asia, Africa, and 

 South America. 



614. In the United States, the growing of Hemp is chiefly 

 confined to Kentucky and Missouri ; ten other States producing 

 trifling quantities only. In 1850 this plant was not cultivated 

 in Michigan. It is supposed to be decreasing in the annual 

 product.
