Cinnamon Oil, Ceylon. — We take the following notes from an English paper 1 ) 

 on the cinnamon industry of Ceylon which does not contain much novel information, 

 but is supplementary to former statements on the subject 2 ). 



Ceylon cinnamon is known to be superior in fine quality to all other kinds. This 

 quality is due to the circumstance that the cinnamon tree finds just in Ceylon favourable 

 conditions for its growth (a suitable temperature, in the mean 85° F = 29.5° C, and 

 ample moisture). The trees attain in Ceylon a high age and not rarely a height of 

 40 ft. The shoots (as a rule 4 to 7) are cut every two years. They are dried by exposure 

 to the air (sweating process) before the bark is peeled from the trunk. When the bark 

 has turned soft after a while, the external layer of cork is peeled off. This portion, 

 as well as the inner and thicker parts of the bark, are brought into the trade as a 

 second-class article in the form of chips; the chips serve chiefly for the distillation 

 of the essential oils 3 ). In drying the pieces, about 3 ft. long, assume the shape 

 of rolls or quills which are pushed into one another, and these "pipes" are shipped 

 in bundles. 



By far the largest portion of the cinnamon goes to the Romanic countries, Spain, 

 Mexico, Central and South America, not so much to the United States of North America. 



The cinnamon oil coming from Annam had, according to Roure-Bertrand Fils 4 ), the 

 following constants: — diBo 1.051; « D — 0°8'; n D27 o 1.6090; acid v. 2.8; soluble in 1 vol. 

 and more of 70 per cent, alcohol ; aldehyde contents 95 per cent. The oil, which had 

 the amber yellow colour of cinnamon oil from Ceylon 5 ), had a sharper and less refined 

 odour than this oil and a sharp burning taste. 



As regards oils from Cinnamomum Mercacloi. Vid., and from C. zeylanicum from 

 the Philippines, cf. page 85 of this Report. 



Citronella Oil. — Within the last years the following weights of citronella oil 

 have been exported from Ceylon via Colombo and Galle 6 ).
