OVER THE ARKA-TAGII FROM KAPA.

On 27th August we continued towards the east-south-east along the northern shore of the lake. The little mountain-chain on that side consists of hard, green, finely crystalline schist, dipping 27° towards the N. 1o° E. Its gravelly scree juts out a long way into the lake, which appeared to be shallow. The gravelly ground alongside the lake was hard. This lake is fed by several small brooks and watercourses, some with deltas, others without. In some places small dunes of coarse sand had formed, a phenomenon rather rare, so far as our experience goes, in Tibet. At its eastern extremity, where it is very narrow, the lake is entered by a stream with muddy red water; and its delta consists of red mud. The lake generally is

of a pure blue-green colour, but its eastern bay is befouled by the red stream. Here again the rock was a red, greatly weathered sandstone. Crystallized gypsum occured in this place, as so often elsewhere in these regions, as a filling of dykes. After that we travelled along the latitudinal valley, which rises gently towards the east and is drained by a stream that, after picking up several tributaries especially from the south-east, enters lake No. II. At Camp XIII (alt. 4898 m.) we found some grass, the first we had seen all day. Of the Arka-tagh and of the range on the south, the continuation of the Koko-schili, we did not see much, as they were for the most part masked by foothills and subsidiary offshoots. The southern range possessed far less snow than the Arka-tagh. The southern versant of the latter, which is composed of a chaos of crests and ramifications of the main range, is
