54 GRIMES : MYINGYAN, MAGWE AND PAKOKKU DISTRICTS. 



from the sand, and when stones lying on the surface are turned over 

 a film of oil and water is seen on their under side. The Burmans 

 call this hill the Yenan Daung (earth-oil hill). Besides this place 

 there are other exposures of the first oil sand, with indications of oil, 

 but at a lower level, in other stream beds, both nortlrand south, 

 the most southerly being in the Magyi Chaung in block 2 of the 

 Yenangyat oil-field, where the oil sand is just under the stream 

 sands. The arguments, which I have used in the case of the 

 Singu oil-field, apply here with, if anything, greater force, and it 

 is most probable that this will be found to be a new and profitable 

 oil-field also. Of its extent it is impossible to speak accurately at 

 present, as there are no detailed maps north of the demarcated blocks 

 of the Yenangyat oil-field, but I may say that the exploitable area 

 will most probably extend from the north part of block B (Yenangyat 

 oil-field) to about six miles north of the mapped blocks. This is 

 only a rough estimate, and possibly the limits may have been taken 

 too far to the south or too little to the north, but it is impossible to 

 say accurately until we have larger and more detailed maps, where- 

 with to geologically examine the country here. 



When working a few miles north of Yenangyat one of the villa- 

 gers brought me two small pieces of amber, which 

 he said he had obtained from the Kyun Chaung. 

 I went with him to this place, which is in block 5 of the Yenangyat 

 oil-field, and the beds which he pointed out to me as having contain- 

 ed this amber were thin bands of yellow sandstones in the shales of 

 Yenangyaung age. These bands were full of fragments of partially 

 fossilized wood, partly converted into coal or replaced by oxide of 

 iron, and of strings of coal. I could not myself find any amber, but I 

 observed several holes, where the Burmans had been digging for it. 

 The villager said that when found it is always in small round balls, and 

 so it may possibly have been derived from beds of the Prome stage, 

 in which it is known to occur.
