gated larynx, and thus breathing and milk injection can go on

The kangaroo browses on the herbage and bushes of more or 
less open country, and when feeding, commonly applies its 
front limbs to the ground. It readily, however, raises itself on 
its hind limbs and strong tail (as on a tripod) when any sound, 
sight, or smell alarms its natural timidity (PI. CXXVIII. 
%. i). 
Mr. Gould tells us that the natives (where it is found) some- 
times hunt these animals by forming a great circle around 
them, gradually converging upon them, and so frightening 
them by yells that they become an easy prey to their clubs. 
As to its civilized hunters, the same author tells us that 
kangaroos are hunted by dogs which run entirely by sight, and 
partake of the nature of the greyhound and deerhound, and, 
from their great strength and fleetness, are so well adapted for 
the duties to which they are trained, that the escape of the 
kangaroo, when it occurs, is owing to peculiar and favourable 
circumstances ; as, for example, the oppressive heat of the day, 
or the nature of the ground ; the former incapacitating the 
dogs for a severe chase, and the hard ridges, which the kan- 
garoo invariably endeavours to gain, giving him great advan- 
tage over his pursuers. On such ground the females in 
particular will frequently outstrip the fleetest greyhound ; while, 
on the contrary, heavy old males, on soft ground, are easily 
taken. Many of these fine kangaroo-dogs are kept at the stock 
stations of the interior, for the sole purpose of running the 
kangaroo and the emu, the latter being killed solely for the 
supply of oil which it yields, and the former for mere sport or 
for food for the dogs. Although I have killed the largest 
males with a single dog, it is not generally advisable to attempt 
this, as they possess great power, and frequently rip up the 
dogs, and sometimes even cut them to the heart with a single 
stroke of the hind leg. Three or four dogs are more generally 
laid on ; one of superior fleetness to 46 pull ” the kangaroo, 
while the others rush in upon it and kill it. It sometimes 
adopts a singular mode of defending itself, by clasping its 
short, powerful fore limbs around its antagonist, then hopping 
away with it to the nearest water-hole, and there keeping it 
beneath the water until drowned. 
The kangaroo is said to be able to clear even more than 
fifteen feet at one bound. 
Rapidity of locomotion is especially necessary for a large 
animal inhabiting a country subject to such severe and widely- 
extending droughts as is Australia. The herbivorous animals 
which people the plains of Southern Africa — the antelopes — are 
also capable of very rapid locomotion. In the antelopes, how-
