During the last few years large quantities of this oil 

 have been exported from Hankow to European and 

 American ports, by far the greater quantity going to 

 America. Of ^54,501 piculs (the picul=133ilbs. avoir.) 

 shipped from Hankow during the year 1905, 49,514 piculs 

 i;vere absorbed by America. So far as can be gathered 

 the applications of Wood Oil in the West are for the 

 manufacture of linoleum, as a substitute for linseed in 

 •other industries, and it is also believed to form the basis of a 

 varnish to compete with that produced from Copal. The 

 oil has poisonous properties, and the refuse cake is 

 employed as manure in China. 



Note also fruits of Aleurites cordata^ R. Br., from 

 Hong Kong. The seeds yield an oil similar to that of the 

 last mentioned. 



No. 440. Candle-Nut or Country Walnut Oil, 

 from the seeds of Aleurites triloba^ Forst., a handsome 

 tree widely distributed in tropical countries. The seeds, 

 strung upon a stick, are burnt as candles in the Sandwich 

 Islands. When pressed they yield a large proportion 

 of pure palatable oil. 



No. 441. Croton Oil, expressed from the seeds of 

 Groton Tigliuw, L., a shrub of India and the Indian 

 islands, a powerful purgative ; employed externally as a 

 rubefacient. 



No. 442. Sweet Bark, or Cascarilla Bark 

 (Croton Eluteria^ Benn.). It is a native of the Bahamas, 

 is aromatic, bitter, and tonic, and was at one time used as 

 a substitute for Cinchona. On account of its agreeable 

 musky odour when burned it is used as an ingredient in 

 fumigating pastilles. It is sometimes inserted in cigars to 

 give a pleasant odour when smoked.

 {Croton niveus, Jacq.), "a shrub, native of Venezuela.
