OIL FROM CITRUS PEEL. 



The essential oils of the orange tribe were dealt with in an article 

 in the Bulletin for September, 1895. 



The object of this note is to publish information received from Mr. 

 J. Ch Sawer, author of " Odorographia," on the ecuelle-a-piquer, the 

 instrument used for obtaining the oil from the peel. He says : — 



" The ecuelle-a-piquer (used in the South of France and North of 

 Italy) is a saucer- shaped vessel about 8 to 10 inches in diameter, 

 usually made of copper, tinned irside, and covered inside with short 

 spikes about J to J inch long. In the bottom of the saucer is a hole 

 about \ inch diemeter leading to a tube about 4 or 5 inches long, closed 

 at t\ e lower end. This tube consitutes the hardle of the tool, also 

 the receiver of the oil running into it from the saucer above. 



" There are larger machines used for obtaining the oil from a 

 number of fruits at a time, with spikes in the lid, which is revolved by 

 machinery. 



" I believe thebest makers of all utensils used in the perfume industry 

 are in France and I would suggest that you apply to Mr. Deroy fils 

 aine, 73 Rue du Theatre, Paris, stating whether you wish a machine 

 to extract the oil on a large scale or only experimentally. If he can- 

 not supply you doubtless he can name someone else." 



THRIPS ON COCOA. 



Samples of Cocoa pods have been sent to Hope Gardens for some 

 time back shewing discolouration, and although only the outer skin 

 was aflrcted, planters were naturally and rightly anxious to ascertain 

 its nature, > nd the possibility of its eventually becoming a pest, and 

 interfering with the cr< p. 



The discolouration of the skin caused at first, some trouble with the 

 pickers, as they said the could not tell when the pods were ripe. 

 However that difficulty was soon overcome by scratching the skin 

 with the finger-nail, for, if the flesh had changed from a greenish to 

 a yel'owish appearance, the pod was ripe. 



The discolouration is due to attacks by a minute, but exceedingly 

 active insect, called " thrips." These insects are not more than one- 

 tenth of an inch long. Their bodies are slender, and the adults have 

 narrow wings, fringed with hairs and lying flat along the back. They 

 puncture the softer parts of plants, and seem to poison the cell*
