 the Records of the Government of India, to which I have not 

 had access. 



A slight reference to the subject is also made by the same gen-

 the Court of Ava, by Captain Yule of the Bengal Engineers. 



Mr. Oldham describes the hills near this station as " throughout 

 composed of sandstones and shaly beds." In another part of 

 the same report he gives a resume of the Geology of the river 

 valley, and writes that, " from the first appearance of the rocks 

 above the Delta of the river up to Kyouklaloung, not far from the
