The geographical range of the Quagga does not appear to extend to the northward of the river Vaal. The animal was formerly extremely common within the colony, but vanishing before the strides of civilization, is now to be found there in very limited numbers, and on the borders only. Beyond, on those sultry plains which are completely taken possession of by wild beasts, and may with strict propriety be termed the domains of savage nature, it occurs in interminable herds. Moving slowly across the profile of the ocean-like horizon, uttering a shrill barking neigh, of which its name forms a correct limitation, long files of Quaggas continually remind the early traveler of a rival caravan on its march. Bands of many hundreds are thus frequently seen during their migration from the dreary and desolate plains of some portion of the interior which has formed their secluded abode, seeking for more luxuriant pastures where, during the summer months, various herbs and grasses thrive. THE DAUW. The Dauw seems to take a middle place between the Zebra and the Quagga. It resembles the former in its shape and proportions, and the latter in the color of its coat. This quadruped is a native of the Cape of Good Hope, and doubtless of many of the mountainous districts of Southern Africa. It lives in arid and desert localities, in droves, and is shy, and difficult to tame. QUADRUPEDS THAT CHEW THE CUD. THIS order of animals is known as the Ruminantia, or the Ruminant Order, because all these animals possess the strange power of ruminating, or of bringing back into their mouth (in order to re-chew it), the food that they have once swallowed. This power is owing to a complicated structure of their stomach, which is divided into several compartments, and which have been considered, though with some exaggeration, as so many distinct stomachs. The first and largest of these divisions is the paunch, which occupies a large portion of the abdomen. The food is here accumulated after being roughly crushed by the first chewing. After the paunch comes the bonnet or cap stomach. In this cap the food is gradually moulded into small pellets, which ascend again into the mouth, by means of a natural movement, and not a convulsive or irregular one as in other animals; these pellets then undergo a thorough chewing and mixing with the saliva. Such is “chewing the cud.” When the food, thus transformed into a soft and nearly fluid paste descends again into the stomach, it goes straight into a third intestine and from this it at length passes into the digesting stomach or rennet-bag.
