 pp. 516, 517. 



Shows from personal observation that the so-called volcanic district 

 of Bisch Balig does not contain true solfataras or other evidence of 

 volcanic action. The observed phenomena are due to combustion of 

 coal-beds of Jurassic age. Bai-schan has not been visited by any 

 European, and may be, as reported, volcanic; but analogy suggests 

 that it is not. F. W. E.

The distribution of the water-courses over the Kashghar and Yarkand 

 country is accounted for. The slope consists of a series of alluvial fans 

 on a large scale, with a gentle inclination, over which the mountain- 

 streams flow in radial directions. E. D.
