GENERAL NOTES 
GEOGRAPHY AND TRAVELS.! 
Asta.— The Sanpo and the Trawadi.—The chief paper inthe May 
issue of the Proc. Roy. Geog. Society is upon the disputed question 
of the sources of the Irawadi. As no one has yet followed the 
Sanpo from Thibet downwards, it is still unproved whether it 
enters the Irawadi or the Brahmaputra. Mr. Robert Gordon 
opposes the commonly received idea by advocating the Irawadi 
view. He bases his belief upon the following points : 
(1) The Salween, which flows to the east of the Irawadi, has 
been proved to rise north of latitude 30°, and thus the country 
_which was formerly supposed to supply the Irawadi is now known 
to be the watershed of the Salween 
(2) The Irawadi at Bhamo, the ‘point where it first became 
known to western geographers, is still one of the largest rivers in 
the world, containing probably two-thirds of its volume in the 
delta. The average discharge at the delta is about 521,794 mil- 
lions of cubic yards, very nearly four-fifths of that of the Missis- 
ippi. But three-fourths of this vast discharge come down in the 
months of July, August and September. August has twenty-two , 
per cent of the entire discharge, February and March only one 
a and a half per cent. At Bhamo Mr. Gordon calculates the ordi- 
_nary high-water capacity at B80; 000 cubic feet per second. 
(3) Chinese geographical annals, extending over twelve hun- 
-dred years, and corroborated by the direct statements of French 
_ missionaries and others, give direct evidence that the Sanpo is 
-~ -the Irawadi, and maps, names of rivers, etc., gime indirect evi- 
| to the same effect. - 
adit Gordon quotes Count Sushen as follows : “ Almost all 
the who could furnish information about this country 
akeen answer to my question, ‘Where does this river come 
om? ‘From Lassa.’ According- to Chinese and Tibetan
