browse, and will feed at any time of the day, although they resort sometimes to the

are not disturbed, especially in some of the native states, nilgai are absurdly tame, 
but in districts where they are much molested they become extremely shy and 
wary. It must not, therefore, be supposed that they can always be easily shot, but 
they afford such a poor trophy that they are not much sought after. When they 
can be found sufficiently far from thick cover they may be speared, and they then 
show capital sport, as they will probably lead a well-mounted horseman a chase of 
several miles. On hard ground I doubt if a cow nilgai could be speared by a 
solitary hunter; the bull, being much heavier, is more easily ridden down.” They
