PLIOCENE BEDS. 69 



tell me that oil has been seen at different times in places which 



they pointed out to me ; these are near the faults, and although 



I had excavations made I could not find any indication of it.

 the hills, and the chances of finding oil by bor- 

 ing between Ayadaw and Gwegyo are not hopeless. 



Around the northern part of the hills the pliocene beds are 



exposed overlying the miocene rocks. These

are of the usual type like those described before, 



and from one of the conglomerates near the base I obtained a tooth 



of Sus sp. 



To the recent beds I will allude in the next section. 



IV. The intermediate country. — The country between the main 

 ranges of hills may be divided into two portions,

 one of pliocene and alluvial country.

 beds * These areas, where the pliocene beds are 



exposed, are like those in the Yenangyaung hills, rugged 

 and barren and so much cut into by innumerable stream beds 

 as to be very difficult to traverse; almost the only vegeta- 

 tion on them is the low thorny acacia-trees (Acacia ferrug- 

 ined) and the bare ground is covered with loose pieces of the 

 hard concretions. Of the nature of the beds there is nothing 

 more to say as they are exactly like those described before, 

 (ii) The flat or rolling country is quite different in character, 

 being largely cultivated and having on it innu- 

 merable toddy palms. This country is covered 

 by a deposit of recent alluvial beds, which is 

 often of great extent, and the thickness of
