134 A Survey of TAR 
this way, there can be any practicable or useful pass.'to’ the Tartarian 
districts, or doubtless the people would have found it, out, and used : it, 
as they do that up the course of the Jdhnavfé:) While I give:itvas ‘my 
opinion, that, under any circumstances, the crossing of the ridge must be 
difficult, ‘I would by no means wish to be understood to assert, ‘that 
I think it impessible, under more favorable’ circumstances, and ina 
year when less: snow has fallen than in the presents; but i seriously 
declare, that situated as we were, it was not possible for us to go further | 
than we did, and that it was with great difficulty we got back. 
Ir is ‘now to be considered, if the supplies of water, produced as 
above. described, are sufficient to form a stream of 27 feet wide, and AS 
inches (mean depth) at the debouche.—It has been stated, that at 
Gangotvi, the breadth of the river on the 20th May, was 43 feet, and its 
depth 18 inches.—The distance thence to the debouche was 22,629 
paces, which I reckon about 11 British miles. In that space, it received 
some supplies, as mentioned in the notes, but they were not abundant.— 
Thus the quantity of water is diminished nearly one halfs but itis to be 
remembered, that on our:return to Gangotré, on the 2d June, the bulk 
of the river was considered as being doubled, it being 2 feet deep, and 
aiso much wider, so that on the 3ist May, we may suppose it to have 
been 21 inches deep, and perhaps 48 feet wide at Gangoirf. It is with 
this mean size, that the cémparison. of the difference of its bulk at 
Gangotri, and the debouche, must be made3 the proportion thus 1s, 
that the bedy er quantity of water would be at Gangotri almost treble 
to that at the deboucke ; but allowing it to be only double, in. this Il 
miles, it will be evident, that in 5 or 6 miles further, there can be little
