The savannahs and marshes of the ancient continent are frequented by birds of great stature: Cursores, Raptores, and Palmipeds. The colossus of the feathered world, the _Ostrich_, which has been aptly surnamed the Camel-Bird (_Struthio camelus_), inhabits the arid plains of the African interior, and frequently penetrates into the Sahara. The male is of a glossy black, with white on the wings and tail; the female wears an uniformly dusky livery. It is the loose flexible plumes of the male which are so prized for a lady's toilette, and which figure in the crest of the prince of Wales. The female's feathers are of inferior value, and improperly designated in commerce, "vulture-feathers." The Ostrich lives with his fellows in flocks of some number. He feeds voraciously on grass, grain, young twigs, and will swallow pieces of wood, leather, metal, or any hard substance. In his apparent want of taste he is probably guided by instinct, for these objects are probably useful in promoting the work of digestion. Some travellers have represented him as a stupid animal; but this is an error, for he displays both vigilance and shrewdness in avoiding the attacks of his enemies. The chase of this bird is exceedingly laborious, for though he does not fly he skims the ground, and his wings impel him forward with a velocity which distances the swiftest horse. But neither his speed nor his strength avails against the stratagems of man. The Arab horsemen surround the flock in a circle, which they gradually contract as they advance, until the poor birds are confined in a very narrow area, and dashing madly against one another, fall exhausted with fatigue. They are then slain by a few blows from a stick. The female lays from ten to twelve eggs in a hole in the sand; she broods over them during the night, occasionally leaving them in the hottest part of the day. In procuring the eggs, which weigh about three pounds each, and are reputed a great delicacy, the natives are very careful not to touch any with their hands, as the parent birds would be sure to discover it on their return, and not only discontinue laying any more in the same place, but trample to pieces all those which have not been removed. A long stick is accordingly made use of to push them from the nest. Another gigantic bird, whose wings are but partially developed, and whose legs are long and robust, the _galeated_ or _helmeted Cassowary_ (_Casuarius_), is a native of Java and the adjacent islands of the Indian Archipelago. His head is surmounted by a sort of osseous crest or horny helmet. In size he is much inferior to the ostrich, not exceeding five feet when erect; but he is robustly built, and of exceeding strength. His plumage is very poorly supplied with feathers, so as to resemble at a little distance, it is said, a coat of coarse or hanging hair. He is a swift runner, like the ostrich; is equally voracious, and not more dainty in his food. [Illustration: OSTRICHES (_Struthio camelus_).]
