Commercial and scientific notes on essential oils. 15 



Clove Oil. — The difficulties which the authorities place generally in the way of 

 the imports of spices, the justification of which is a debatable question, having been 

 overcome by measures which the industry took on its own account, this important 

 oil is again being manufactured on a large scale. Clove stems are also being imported 

 again in considerable quantities. Of the latter, large bulks have accummulated in 

 Zanzibar and have for the present not found any satisfactory sale. The prices for 

 cloves and clove stems have much been lowered of late, and the large stocks available 

 in all the chief markets justify the expectation of further price reduction. We spoke 

 in our last report of the rumoured erection of clove oil factories on the islands of 

 Zanzibar and Pemba. So far there have been no confirmations of these news. 



Coriander Oil. — The cultivation of coriander occupied in the year 1917 in Morocco 

 an area of 2590 hectares, principally in the Shauya. In localities, where conditions 

 were considered favourable and good results were obtained, an extension of the 

 plantations is being contemplated. The cwt. of coriander was in 1919 paid 115 fr., 

 against 25 fr. before the war 1 ). 



Cumin Oil. — Among the aromatic plants of Morocco the Roman caraway, the 

 cultivation of which covers an area of 5400 ha., claims the first place. The fruit are 

 a favourite spice of the oriental nations. In Marrakesh the cwt of cumin cost in 1919 

 110 fr. The exports of cumin fruit amounted in 1916 to 1100 tons 2 ). 



Oil from Cymbopogon javanensis. — The inaugural dissertation by ). ). Hofmann 

 on the essential oil of a species of Cymbopogon, which we mentioned on page 20 of 

 our Report of 1919, has been reproduced in the Pharm. Weekblad 56 (1919), 1279 3 ).
