Gingos " Liambe " ; the Portuguese name is " Canhamo." This com- 

 modity, which is for the most part if not wholly composed of the cut- 

 up leaves of hemp, is eagerly sought for in the markets by the natives 

 at Loanda and in all the interior of Angola for narcotic smoking ; 

 indulgence in it constitutes one of the most pernicious of their vices, 

 especially with the slaves, who when addicted to Riamba smoking 

 become nearly useless to their owners. The plant is cultivated in all 

 the interior districts of Angola, but always in situations more or less 

 retired or lonely, in order to withdraw the plantations from the notice 

 and greed of passengers. Htemorrhage of the nose is the very frequent 

 consequence of this smoking intoxicant ; the natives in the interior of 

 Huilla are accustomed to cure it with the powdered panicles of 

 " Encotahote '' (Cf/mhojwgo}/ schanianthiis Spr. var. sttjptkus Rendle ; 

 Welw. herb. n. 7526, Coll. Carp. 1093 aud 1091), an application of 

 which nearly always has the desired effect. 



For an account of the constituents of hemp resin, see a paper by 

 T. H. Easterfield and T. B. Wood in Proc. Cambr. Phil. Soc. ix. 3, 

 pp. 144-8 (1896) ; and on its pharmacological action, by C. R. 

 Marshall, I.e., pp. 149-50. 



The dried herb is packed for sale in cylindrical sausage-shaped 

 parcels, 2 to 3 ft. long and about 4 in, thick. The fruits of the 

 Adansonia, called "Mucua," are used by the negroes for smoking the 

 Riamba ; see ante, p. 80.
