I went hunting twice, and Wang, the carpenter, climbed a high mountain 

 near by. This is a poor place to collect, so we will move towards Tatsienlu. 

 I never saw woods so devoid of birds, etc., as these are now. 



Ho, the skinner, was sick, but managed to do his work up-to-date . I 

 helped him some. 



It is a very hard problem how to keep this expedition in provisions. 

 Our Ohinese collectors must have Mce, and this increases the cost of their food. 

 We are in territory much of the time where vegetables will not grow, and not even 

 wheat or barley. Food must be brought a long way. Butter and milk may generally 

 be procured, but not always. Sometimes a sheep may be bought and eaten. 



Aug. 6. Secured mammals 491-2, and about ten birds. 



We crossed the Wa-Hu pass on the way back towards Tatsienlu. We secured 

 some good flies, and a few moths and butterflies. The full moon is out, so night- 

 moth catching does not yield results. 



From the top of the pass we got a fine view of a snow mountain range di- 

 rectly westward. Some high peaks are bare, but others are covered with snow. 

 We saw some glaciers. There is one glacier that is an immense snow drift, the 

 enow drifting over mountains that are to the west of the drift. The drift must 

 have a tremendous depth . 



The far-spread story that the high-waters of the Yangtse and its tribu- 

 taries in the summer are due to the melting snows of Tibet is a myth. There is 

 very little snow, comparatively, in Tibet to melt. Very little snow falls in 

 Tibet in the winter-time, and its melting does not cause floods. During the 

 summer, on hot sunshiny days, the streams are at their lowest. On cold, rainy 

 days or just after heavy showers, the streams are at their highest. Most of the 

 flood-waters of the Yangtse and its tributaries in the summer are due to heavy 

 rainfall east of Tibet, in Szechuan, and in other parts of China. This paragraph 

 is the result of years of observation arid inquiry.
