1848.] Routes from Darjeeling to Thibet. 495 



Yangpoong. — Leave the Rungbee to the left and aseend to this place, 

 where there is a customs chokey of Sikim. Salt is brought into Sikim 

 by this route from Thibet, but the trade is liable to interruption from 

 the Nepalese, who stop its passage in the portion of their territory 

 through which the road runs beyond Choolongkook. 



Gomothang. — Ascend the Pekionglah ; cross the ridge and descend to 

 this stage, which is on a small stream of the same name. 



Chodomdong. — Cross the Gomothang stream and ascend along it to 

 this place. There is a lake here which is the source of the Gomothang ; 

 it runs easterly and falls into the Ratong below the junction of the 

 Choorong with that stream. 



Choolangkeok in Nepal. — Ascend to the crest of Domdouglah, cross 

 it and descend to this ground. The Domdonglah ridge forms the pre- 

 sent boundary between Nepal and Sikim, and is a continuation of Kung- 

 lanamoo. There is a small stream at this sta°;e ; it is a feeder of the 

 Tambur Koosi. 



Yamgatcha. — Ascend and cross the Giroonglah, whence descend to 

 this stage, where you fall into the Jongri road. 



No. 3. 



Route via Lachen and the Latong Pass. 



From Choongtam, at the confluence of the Lachen and Lachoong 

 rivers to 



Dema. — All the way along the Lachenchoo, direction north-west. 



Latong, on the plain of Thibet. — About 5 cos from Dema ascend to 

 the ridge of Latong, cross it, and without any descent you are on the 

 Table-land of Thibet. On either side of the pass there is a high peak. 

 You can go round by the bed of the Lachen, but the pass is the better 

 route. Taloong is on the Lachenchoo, which rises to the eastward 

 from a lake near Cholamoo.* The Lachen cuts off Kunchin from the 

 range to the eastward. 



Geeroo. — Over the level land in a north by west direction, and here 

 you join the road from the Dankia pass. There is a fifth route to Thi- 

 bet east of Kunchinjinga and west of this Lachen one, of which I have 

 no particulars. It strikes oif at Garrhf on the Teesta, whence the
