SINO-MONGOLIAN FRONTIER 
warded with a good collection of small mammals, 
including about ten different species, namely, 
the hare (Lepus tolaz), the pika (Ochotona dauurica), 
the allactaga (Allactaga mongolica), the gerbil 
(Meriones unguiculatus), the susik (Citellus mon- 
golicus umbratus), the striped hamster (Cricetulus 
griseus obscurus), Campbell’s hamster (Phodopus 
campbelli), two voles (Microtus angustus and 
Microtus warringtoni) and the common mouse (Mus 
wagnert mongolium). 
Mr. Larson very kindly placed his ponies at 
our disposal, our own being rather worn out with 
the long journey, and he arranged for several 
very successful antelope hunts, so that we secured 
eight good skins for our collection. Altogether 
we shot eleven antelopes. 
The method adopted by our Mongol guides in 
hunting these antelopes gave us excellent sport 
and required good horsemanship, a quick eye and 
rapid and accurate shooting. Following is a 
typical example of a day’s hunting in these parts. 
Starting early in the morning we rode westward 
for a mile or so till we reached Mr. Larson’s herd 
of ponies, where we changed our mounts. For a 
few minutes there was a scene of confusion as the 
herders chased the chosen ponies, but at last they 
were caught and saddled, and away we rode 
toward some low, rocky hills. How those ponies 
flew! regardless of holes, rocks, tufts of “ nigger 
head”? or swamps! They took everything in
