SINO-MONGOLIAN FRONTIER 



Neither of these towns is of much import- 

 ance. 



Ning-wu Fu is a poor looking city of no great 

 importance. Its walls, temples and gate towers 

 are in a sad state of disrepair. It is situated on 

 the Hui Ho, a tributary of the San-kan Ho, near 

 the source of the Fen Ho. The inner loop of the 

 Great Wall passes from east to west about five 

 miles to the north, and its towers may be seen 

 from the city wall. 



On a hill behind the city lie two very large 

 tower-forts, long abandoned and allowed to crumble 

 and decay. 



The business quarter of the city is small and 

 unimportant, showing how poor the inhabitants 

 are. There is no special produce or manufacture, 

 and but for the fact that the surrounding dis- 

 tricts are governed from this city, it would doubt- 

 less cease to exist as such. 



At Tung-tsai near Ning-wu Fu we collected a 

 good series of molerats (Myospalax fontanus)^ 

 chipmunks (Eutamias asiaticus intercessor) and 

 pikas {Ochotona hedfordi). Of these the molerat, 

 which was first identified as Myospalax fontanieri 

 was new to science, while the chipmunk proving 

 to be an intermediate form between the Chihli 

 species {E. a. senescens) and that from the Ordos 

 {E. a. ordinalis) was described as a new sub-species.

 tona sorella) and the allactaga (Allactaga mongolica)
