cuttings extending for several miles, show that 

 of these bands in a very great thickness of 



One such cutting on the railway occurs a 



little to the west of 

 Jfcale band at Let- Letkaung vilIag6j at thg 



foot of the final ascent to 

 Maymyo (Loc. 26, 4), where some slightly 

 carbonaceous shales are interbedded with the 

 limestones, dipping N. E. at an angle of 17 

 degrees, and contain specimens of a small 

 Lincjula and other fossils, none of which, 

 however, are specifically determinable. Another 

 band of shale was found in a cutting about 

 three miles east of Kyaukme station (Loc. 31, 

 E 2), greatly contorted and in places vertical, 

 portions of which were found to contain the 

 shells of a minute Estlieria, somewhat 

 resembling E. mangiliensis Rupert Jones, from 

 the Panchet beds of the Indian Gondwanas, 

 according to Mr. Ccwper Reed, as well as 

 some very fragmentary plant remains (Fig. 6). 

 Portions of this band also are carbonaceous , 

 and it is indeed not unusual to find strings and 

 pockets of coaly matter 

 among the Plateau Lime- 

 stones. One of these occurrences, which looked 

 rather promising, w a s found close to Manhpwi 

 (M:in-hpa) station (G 1), between Hsipaw and 

 Lashio, and was carefully examined in 1904 

 by Mr. Datta, who traced the coaly layer for 

 some distance, but was unable to find any 

 seam of value as fuel. In fact, the sample 

 analysed in the Geological Survey Laboratory 

 was found to contain more ash than carbon.
