 importance, and tin- rhubarb told in the bazars of the plain* is ordinarily affirmed 

 to be of an inferior grade to the Chinese drug, and till morn to that imported 

 t>. .in London. Considerable quantities are, however, annually conveyed to the 

 plum* from the Kangra district of the Pan jab. An inquiry in 1894 revealed the 

 fact that the exports from that valley came to about 1,000 maunds a year. 

 Further, it was stated to be largely used in the fabrication of certain external 

 applications (Pre*. Add. Med. Congress, Cole., 7). It is remarked in the Phar- 



nceia of India that were the Himalayan rhubarb cultivated with duo care,

 be obtained. [Cf. Paulus Algineta (Adams, transl. and Comment.),

The BARK is exported from Mergui to Rangoon, and a considerable trade is 

 also done in it from the Perak coast. It yields a DYE and TAN. Samples of 

 bark of K. nmrmnata were sent to the Imperial Institute in 1899 (Imp. 

 Inst. Tech. Repts., 1903, 186-90), and wore found to vary greatly in yield of 

 tannin, one sample giving over 27 per cent., while another gave only 4 per cent. 

 An extract, prepared presumably from the former sample, contained 76 per cent, 

 tannin. In the Report of Forest Administration in Burma (1904-5, 19), mention 

 is made of the establishment of a tannin factory in accordance with a system 

 recommended by Dunstan. So far the extract thus prepared sold at lees than 

 it cost. For dyeing cotton, an extract was declared superior to that of other 

 mangroves, but much inferior to the best qualities of cutch. The fruit is said 

 to be sweet and edible, and a light wine is made from the juice. From the aerial 

 roots, salt is occasionally extracted. The wood is reported to be good but rarely 

 made use of. [Cf. Ind. For., 1897, xxiii., 413; Hooper, in Agri. Ledg., 1902,

 eastward to Afghanistan ; often extensively cultivated. Inzenga (Ann. di 

 Agri. Sic., etc., Palermo, 1852) wrote an interesting paper on the cut- 

 tion of this plant (translated into English by Sir H. Yule, in Edinb. Bot. Soc. 

 Trans., 1867-8, ix., 341-55). 



The leaves contain a colouring matter, and together with the twigs are largely T 

 used in Europe for TANNING. They are also imported into India, usually from 

 Sicily, for use in the large European tanneries. Morocco leather in tanned with 

 this material, and it is usually held to be one of the best tans for leathers intended 

 for use in bookbinding. In the Kew Bulletin (1895, 293-6) an account of the 

 manufacture of and trade in Sicilian sumach is given. The leaves ripen about
