HISTORICAL SUMMARY. 29 



Chapter II.— THE OCCURRENCE OF PETROLEUM IN 

 THE DISTRICTS OF PROME AND THAYETMYO. 



Although not quite falling within the scope of this memoir, it will 

 be useful, for the sake of completeness, to mention the occurrences of 

 petroleum in the above districts. I paid a flying visit to Padouk-bin 

 and Banbyin early in the rainy season of 1892, but partly on account 

 of the rains, partly on account of the dense jungle, I was not able to 

 see much for myself, and, as my time was limited, I could not examine 

 the geological features of these localities as well as of others. I follow, 

 therefore, chiefly Mr. Theobald's description, 1 adding remarks or 

 observations of my own. 



1. — Geographical position. 

 Mr. Theobald mentions the following localities :— 



1. Yenandoung, 12 miles south-west of Myanoung, Lat. i8°9', Long. 95 12/ 



2. Padouk-bin, Lat. ic^i', Long, 95°ii', about seven miles west by north from 



Thayetmyo, 



3. Banbyin, Lat. I9°2i' Long. 95°io'. about 11 miles west-north-west of 



Thayetmyo. 



4. Toungboji, about ii£ miles west from Prome Pagoda, about Lat. i8°2o', 



Long. 95V. 



As already noticed by Mr. Theobald, all these localities are situated 

 on the western bank of the Irawadi river, and he mentions no 

 occurrences of petroleum within the area of the Pegu Yoma, that is 

 to say, on the eastern side of the Irawadi. 



2. — Geological features. 



Mr. Theobald states that all the localities are situated among the 

 nummulitic rocks or the still newer tertiaries. I am unable to verify 

 this statement with regard to the 1st and 4th locality, but as regards 

 Padouk-bin and Banbyin, I can say, from personal experience, that 

 the series there developed must be considered to belong to the Pegu 

 division. Mr. Theobald states that at Padouk-bin the rocks are " soft, 

 earthy bluish sandstones and shales of the newer tertiaries." From 

 this we may conclude that he does not consider them as eocene.
