The spirited view herewith presented, representing the "Fall of the
Giraffe" before the rifle of a sportsman, we take from the Illustrated
London News. Hunting the giraffe has long been a favorite sport among
the more adventurous of British sportsmen, its natural range being all
the wooded parts of eastern, central, and southern Africa, though of late
years it has been greatly thinned out before the settlements advancing
from the Cape of Good Hope.
[Illustration: THE FALL OF THE GIRAFFE.]
The characteristics of this singular animal are in some particulars those
of the camel, the ox, and the antelope. Its eyes are beautiful, extremely
large, and so placed that the animal can see much of what is passing on
all sides, and even behind it, so that it is approached with the greatest

difficulty. The animal when full grown attains sometimes a height of
fifteen to seventeen feet. It feeds on the leaves and twigs of trees
principally, its immense length of legs and height at the withers
rendering it difficult for the animal to graze on an even surface. It is not
easily overtaken except by a swift horse, but when surprised or run
down it can defend itself with considerable vigor by kicking, thus, it is
said, often tiring out and beating off the lion. It was formerly almost
universally believed that the fore legs were longer than the hinder ones,
but in fact the hind legs are the longer by about one inch, the error
having been caused by the great development and height of the withers,
to give a proper base to the long neck and towering head. The color
varies a good deal, the head being generally a reddish brown, and the
neck, back, and sides marked with tessellated, rust colored spots with
narrow white divisions. Many specimens have been brought to this
country, the animal being extremely docile in confinement, feeding
from the hand, and being very friendly to those who are kind to it.
