August 1." W e crossed the Wa Hu Pass, the altitude of which i s 16400 

 feet. We saw a great range of snow mountains to the west, but the great 

 mountains to the east were hidden behind nearby mountains. 



We made a long day's journey, reaching Tang Gu, a village with a few 

 houses which is at the highest point of human habitation, altitude 15600 feet. 

 Houses are not found in Tibet, generally about 15500 feet. Above that are 

 merely tents of nomads. 



We secured two small mammals, nos. 481-482. One seems to be rare . On 

 the south side of the Wa-Hu Pass, for over ten miles, we went through virgin 

 forests of great trees, fir, spruce, etc., of great size. They had a great deal 

 of moss hanging from their limbs.

 I have not eaten any vegetables for days. Today I ate two raw potatoes rather 

 than wait until they were cooked. 



The people in this village are mostly Tibetans, but there are a few 

 Chinese, mostly men.

 without them there is no such thing as a successful collecting expedition. Our 

 guide led us by the wrong road, and we had to return, after an hour of travel, to 

 the place we started from. W e got another guide, and went oh. There are two 

 very small villages quite close together at Gien Long Shien, with a total of about 

 twenty-five houses of all kinds. The villages are over J a mile apart. In the 

 main village there are about a dozen houses. Most of these also figure as shops. 

 Some sell almost nothing but potatoes, or something of the kind. We found only 

 two boxes of matches in the place, and the price asked was about ten times the 

 real value of the matches. We did not purchase them. We purchased some potatoes,
