462 APPENDIX. 



which is described to me as larger than the Sadiya Brahmaputra, but inferior to the great 

 united stream of the Lohit. 



If it were incumbent on me to mention every statement with which M. Klaproth 

 has thought to strengthen his arguments, I should have to quote P. Gaubil's (mere) opi- 

 nion, that M. D'anville was right in placing Ava on the great Yarou Ssanpou — (he 

 does not say a word about its entering Yunnan) — and the evidence of the maps published 

 during the reign of Khian-long, on which it is written in Manchou* characters, 

 opposite to where the Dzangho-tchou or Yarou Dzang-bou-tchon leaves Thibet, that 

 this river passes through the country of Lokabadja (or H'Lokba), and enters Yunnan ; 

 but, as I have proved satisfactorily, I hope, that so important an error has been com- 

 mitted on this point, surely that whole mass of evidence will no longer be thought trust- 

 worthy. 



However, in justice to M. Klaproth, I must draw attention to the large eastern 

 branch of the Irawadi, called in my map by its Singfo name, Shumai khaf — I ask, had 

 M. Klaproth been aware of the existence of this considerable river, should we ever 

 have heard of the Pin-lang-kiang in Yunnan ? or seen the petty Banmo rivulet magnified 

 into a mighty stream ? I think not ; and those who inspect my map will agree with me. 

 With regard to the origin of the Shumai kha, I have no positive statements to offer ; 

 the Singfos are generally of opinion that it is something larger than the western branch, 

 though not materially, and it seems not at all improbable that it is the river mentioned by 

 the old man who was captive amongst the Lamas, as rising in the snowy mountains of 

 the Khana Debas country, and flowing to the south near where he saw the source' of the 

 eastern branch of the Dihong turning to the N. W.% 



If the opinion of Mandchous and Chinese be deserving of confidence, is not that of 

 the Thibetians resident upon the Sanpo equally so I 



* These maps have led M. Klaproth into an error, acknowledged by himself— for he corrects it in his second 

 map. It is written similarly in Mandchou, opposite the " Moun-tchou," that it unites with the Yaron Dzangbo in 

 Lokabadja. M. Klaproth now considers it to be our Dihong.
