When suffering with extreme hunger, he will attack man, but this he will do only in very rare cases. As he lives entirely upon dead animals, he is more of a thief and glutton than a robber and murderer. He depends mostly upon flight and darkness for his protection, and rarely ventures a direct attack. With all his unlikable habits he is truly valuable as an agent of public salubrity, and an important officer of the desert "commission of highways."

These public scavengers, while especially fond of carcasses and putrid flesh, are not averse to a little fresh meat occasionally. The jackal is truly the follower or purveyor for the lion, and oftentimes they work together. Jackals will gather in large numbers near a lion's den and howl and scream until the lions come forth to disperse them. As soon as a lion appears they stop their noise, but when he is out of sight, they immediately begin again. This is done because game is near, and the wise jackals wish the lion to kill the game. When this is done, and the lions have eaten all except the bones, the jackals have their small feast of scraps.

These weird night prowlers have ways all their own, as any one who has spent a night in a tropical desert can attest. Imagine yourself on the Syrian plains between Bagdad and Damascus; a small white tent, and a starry sky: the silence is appalling, and you are just about to have your first sleep in the desert. Away, away from the distance comes a mournful, ghostly cry. Suddenly it ceases and like myriads of echoes it is repeated in hideous intensity—a babel of cries weird beyond description—so fierce and screeching as to be almost blood-curdling. It seems to come from all directions and distance out of measure! Vibrating over the sands and through the rocks, filling the immense void, crying out as it were for the sphinx, a veritable de profundis of the wastes. The vultures, who hold the fort during the day have given way to the night shift, the jackals. These come from all directions; from the caves in the earth, from among the rocks, from here, there, and from everywhere to take up their hygienic services where it has been left off by the day scavengers.

If you were near an oasis in the desert at the close of day, you would suddenly hear from the hot, barren sands a deep and peculiar sound. It swells and grows as an approaching wind, growing louder and louder as it comes nearer. Suddenly by the light of the camp fire, you see myriads of horrid green eyes, like ghost torches in a graveyard, and hear gnashing teeth, greedy in anticipation of the garbage you have thrown away.

These hyena hordes are frightfully ugly, but rarely dangerous to man. They visit every oasis settlement in immense numbers, howling, yelping, and fighting for any bit of offal they may find. Not a particle of garbage remains. At the first sign of dawn, they disappear like rats from a burning building, and seek their caves to digest their ignoble banquets.

No human street-cleaner could ever excel their work. No matter how large the garbage pile, no matter how many dead dogs, cats, and donkeys in a village street, no matter how unspeakable the offal, it all vanishes as completely as though it had been burned. Not a piece of bone, not a single chicken feather remains. The natives have no fear of the hyena; a small child armed with a stick can put to flight a dozen of them. They are the lowest of cowards, and will flee from their own shadows.

THE MONGOOSE IS A SCAVENGER OF THE WORST TYPE, FEEDING ON RATS AND MICE AND SNAKES, AND EVEN POULTRY.
