There is no more delightful study than Natural History in its practical form, where the wild beasts and their ways are actually presented to the observer in their native lands, and he can examine their habits in their daily haunts, and watch their characters in their wild state instead of the cramped limits of zoological collections. At the same time we must confess that the animals of a menagerie afford admirable opportunities for photography, and are most instructive for a rudimentary preparation before we venture upon the distant jungles where they are to be found in their undisturbed seclusion. It is commonly supposed that wild animals that have never been attacked by fire-arms are not afraid of man, and that deer, antelopes, and various species which are extremely timid may be easily approached by human beings, as the creatures have no fear of molestation. My experience does not support this theory. Nearly all animals have some natural enemy, which keeps them on the alert, and renders them suspicious of all strange objects and sounds that would denote the approach of danger. The beasts of prey are the terror of the weaker species, which cannot even assuage their thirst in the hottest season without halting upon the margin of the stream and scrutinising the country right and left before they dare stoop their heads to drink. Even then the herd will not drink together, but a portion will act as watchers, to give notice of an enemy should it be discerned while their comrades slake their thirst. It is a curious and inexplicable fact that certain animals and varieties of birds exhibit a peculiar shyness of human beings, although they are exposed to the same conditions as others which are more bold. We see that in every portion of the world the curlew is difficult to approach, although it is rarely or never pursued by the natives of the neighbourhood; thus we find the same species of bird exhibiting a special character whether it has been exposed to attack, or if unmolested in wild swamps where the hand of man has never been raised against it.
