Sudan Gum. 



I have the honour to inform you that the attention of the 

 Central Economic Board has been drawn to the Article xix. 

 " Persian Gum " in Kew Bulletin No. 4 of 1906, in which it is 

 stated that Persian gum is substituted for Gum Arabic at Assouan 

 and is fraudulently exported as gum from the Sudan. I am 

 directed to request that you would kindly have a contradiction of 

 this statement published as enquiries show that no such practice 

 exists and that the above mentioned paragraph is based on a 

 misapprehension of the true facts of the case. If the statement 

 is allowed to pass without comment it is calculated to depreciate 

 the value of Sudan gum. 



. Pl jbably Professor Sickenberger, who is quoted as the authority 

 in this instance, has been misinformed of an incident which 

 occurred some fifteen years ago. At that time the Sudan had not 

 been reconquered. Consequently supplies of gum were small and 

 fetched very high prices. At about that date a Cairo merchant 

 purchased in Assouan a large consignment of what he believed to 



Wn£wP m *i • + W f in faCt Persian % um which had Probably 

 LT produced into Assouan in the manner mentioned by Pro- 

 fessor Sickenberger. The matter formed the subject of le-al 

 proceedings n Cairo in which the person who sup, led me with 

 this information acted as expert witness.
