536 Note on the Construction of the Map of the [Nov. 



tween Tirthapuri and Kyunlung, but this at least, I have proved to be 

 quite wrong, no part of the lake extending so far west, and the river in 

 question being properly the Darma Yankti, rising in the Byans Hima- 

 laya. In order to make this part of Hearsay's (?) map unite with my 

 own, I have been obliged to bend down the portion of his route next 

 east of Tirthapuri 2 or 3 miles to the southward, so as to enter the 

 Gangri valley south of Kailas and Darchin, and the rivers crossed by 

 this route have been similarly adjusted to meet the Lajandak Sutlej. 

 In other respects Hearsay's map, as also Moorcroft's narrative, agrees 

 very well with the information I have received from the Bhotias, and I 

 have been able to identify many points of the route of those travellers 

 with the Bhotias' descriptions. In the hilly ground between the Sutlej 

 and Gartokh, I have merely had to insert the names of a few streams, 

 encamping-places, &c. in Gugi, i. e. the valley of the Sutlej ; I have 

 added some villages and hamlets and corrected the names of others pre- 

 viously mapped, together probably all that exist (and more than are at 

 present inhabited) from Mangnang eastward, many villages in Gangri 

 were ruined by the plunder of the invading Sikhs in 1841, and have 

 since been deserted. I could not get so much information about the 

 country west of Mangnang, and the mapping of that part is compara- 

 tively defective, but I have obtained a material correction for the course 

 of the Sutlej there, and the position of Tholing, hitherto wrong on all 

 maps. 



All the routes in Gnari, with the several encamping-places on them, 

 are the result of most minute inquiries, where not personally explored. 

 The road from Laptel via Shelshel to Dungpu, and thence back to 

 J war by Chirchoon, I explored myself in June last, 1846, without sur- 

 veying instrument however, and the present draft of it is subject to the 

 possible correction suggested for the positions of Laptel and Balch, (viz. 

 a mile or two more westward.) For the routes on information, I am 

 indebted chiefly to the Jwari Bhotias (particularly to the family of the 

 Patwari of Milam) who so far surpass the others in intelligence that I 

 learned more from them about the lakes and Pruang than from the 

 Byansis, whose constant resort is to those places, and these parts of my 

 map are perhaps as correct as they could be made without personal 

 exploration.
