hunter must not only keep out of sight and out of hearing, 

 but must also avoid detection by a third sense, that of 

 smell. If he attempts to approach this game from the 

 windward side, they are almost sure to detect him and to 

 escape, often without his being aware of their presence, 

 unless he afterward discovers their tracks. 



The moose is an awkward-looking animal, with its long 

 hump nose. The antlers are spread out into a flattened 

 " blade " near the tips. The moose lives in marshy for- 

 ests. There is a considerable number in northern Maine, 

 Nova Scotia, Alaska, and in British Columbia. A few 

 remain in Idaho, in the northwestern part of Montana, and 

 in the region of Yellowstone Park. The moose and deer 

 feed almost entirely on twigs and leaves, that is, they 

 "browse," while elk feed to a considerable extent on grass, 

 like our domesticated cattle. 



The Camel. The camel has but two toes, with large, 

 soft pads. The hump is a storehouse of fat. They can 

 go without water longer than most animals, but this is no 

 more than might be expected of an animal accustomed 

 to living in a desert country. 



The Giraffe. The giraffe is remarkable for the extreme 

 length of its neck. Nevertheless, it has but seven cervical 

 vertebrae, the same number that we have, the increase 

 being due to the lengthening of the individual vertebrae. 



The Elephants. The elephants are essentially ungu- 

 lates, having five toes, each incased in its own hoof ; but 

 on account of the peculiar development of the nose into a 

 trunk, or proboscis, most authors place them in a separate 

 order. The excessively long snout is flexible, very muscu- 

 lar, and serves as a hand in conveying food to the mouth. 

 This arrangement seems especially desirable for an animal
