50 POPULAR OFFICIAL GUIDE. 
The Wild Swine of the world are here represented by three 
noteworthy species: 
The Red River-Hog, (Potamochacrus pencillatus), of West 
Africa, is about the only handsome species of swine that 
Nature has produced. In form it is compact and well-turned, 
its long pencil-tipped ears are of pleasing pattern, and its 
hair is a rich auburn color, and the temper of our specimen 
is everything that could be desired. Beside it is shown 
“‘Clarence,’’ the East African Wart-Hog, (Phacochaecrus 
aethiopicus), who is equally interesting, but in a different 
way. This species is very weird in form. The Collared 
Peccary, (Tagassu angulatum), beside it is more like the wild 
swine of Europe and Japan, and is not nearly so dangerous 
as general reputation demands. 
The Kangaroos.—Seldom is there found in Nature a group 
of large-animal species whose members are so monotonously 
similar in general appearance as are the Kangaroos and 
Wallabies, of Australia. The great majority are either gray 
or gray-brown, and the only striking variation is found in 
the big Red Kangaroo, (Macropus rufus). 
THE WHITE MOUNTAIN GOAT, No. 48. 
Fortunate indeed is the zoological park or garden which 
can exhibit even one living specimen of the White Moun- 
tain Goat. It is a very difficult matter to take an animal 
from a rarified dry atmosphere, at an elevation of 8,000 
feet, and induce it to live at sea level, in a dense and humid 
atmosphere, on food to which it is by nature wholly un- 
accustomed. 
We have been successful in establishing here, on a breed- 
ing basis this rare and difficult animal, (Oreamnos mon- 
tanus). One kid was born in 1908 and another in 1910, and 
both have thriven, the former now being so large as to look 
like an adult specimen. 
For some subtle reason which we can not explain, these 
animals—like the chamois and mouflon quartered in small 
pens near the Small-Mammal House—do not thrive in any 
of the large, rock-bound corrals of Mountain Sheep Hill. 
They are kept in a rock-paved corral near the Pheasant 
Aviary and the Crotona Entrance, and to their use has been 
devoted a rustic barn, which they shelter in or climb over, 
according to the weather, To see them walking nonchalant-
