(v) The Mangrove Forests of the Basse in Coast of 

 Burma. 



The mangrove forests of the Bassein District are found 

 between the mouth of the Laumgyi River and that of the 

 Kyonkadun, and also in the Mwedon and Pokweyo 

 forests. The other areas in which mangrove forests are 

 found in this locality are the Kyagon, Ngyputaw, Einme, 

 Sinma, and Bassein Ranges. 



From the forests lying between the Laumgyi and 

 Kyondakun Rivers about 5,000 mangrove trees are 

 extracted annually. These trees are stripped of their 

 bark, which is taken to Rangoon via the ports of Pyapon 

 and Begale, where the Irrawaddy Flotilla Co/s boats 

 call. The cost of extraction of the bark to the above 

 ports is estimated to be Rs. 12-8-0 per ton. The man- 

 grove forests of the other above-named forests are not 

 worked at present, as there is no demand for the bark. 



4. THE VALUE OF MANGROVE BARKS FOR THE PREPARA- 

 TION OF TAN EXTRACTS. 



This note lias not been prepared with the object of deal- 

 ing with the value of the various species of mangrove 

 bark for tanning purposes, but to demonstrate, the possi- 

 bilities of utilizing mangrove bark, and furnishing infor- 

 mation as to cost of extraction, quantities available, 

 suitable localities, labour, and local conditions. It will 

 therefore be sufficient to mention some of the more 

 important reports which have been published in the past, 

 and which demonstrate the value of mangrove barks for 

 tanning purposes. 



Many reports have been written on the analysis of man- 

 grove bark and mangrove extracts; all of these it would 

 be impossible to mention without dealing with the subject 

 in detail. Amongst the most important publications and 

 correspondence on the subject are : () A report by Dr. 

 Hooper on certain tannin extracts prepared in the 

 Pyinmana Forest Division, Upper Burma, 1898. (iiy
