An old, fat zebra stallion, round-barreled and half-asleep, snorted suddenly, and stared with surprise at the sight of a black-backed jackal galloping as fast as circumstances would permit him, with the wide-mouthed head of a python in his jaws, and the remaining long, painted body trailing out behind.  The snake was not going with any pleasure, and his wriggling tail was feeling for a hold every inch of the way, and if he could have got one—­oh, jackal!  But he could not, for the jackal kept on going, and the snake’s after-length kept on trailing out straight, like a loose rope behind a boat, through the perishing glare and the heat-flurry that seemed to be making the whole world jump up and down, as it does when you look at it over the top of a locomotive-funnel.

Snakes take a long time to die, or to seem dead, even with a double set of glistening sharp teeth scrunching as hard as their owner knows how into their neck.  At last, however, after a final series of efforts to get, and keep, in the shape of a letter S, the python’s tail gradually ceased to feel for a hold, and the writhing strain in the jackal’s jaws relaxed.  Still, our Mesomelas was taking no chances, and he galloped home with his capture before he stopped, as proud and happy an old dog, rascally jackal as ever cracked a bone on a fine day.

He was a little puffed, and more than a little puffed up, and it may have been that he did not keep his eyes all round his head, as a jackal should always do.  Anyway, there, in the gathering shadows of night, came a waiting, watching shadow, that was presently joined by another, and the two—­their eyes glinted once in a nasty metallic fashion—­stood head to head, watching him.

By the time Mrs. Mesomelas had hobbled out to view the “kill” for herself, and snarl her appreciation—­truly, it was a strange way of showing it—­with thin, wicked ears laid back, and more than wicked fangs bared, the waiting, watching shadows had crept forward a little, on their bellies, head up, and—­Mrs. Mesomelas, with the quick suspicion of motherhood awake in her, saw them.

The snarl that she whipped out fetched the jackal round upon himself as if stung.  Then he saw, and understood, and rage flamed into his intelligent, dog’s eyes.  It was the side-striped jackals, Mr. and Mrs., plotting to loot his “kill.”

It was the black-back who attacked.  Perhaps he knew that one secret of defense is swift and unexpected offense.  Anyway, he attacked, sailing in with his dancy, chopping, in-and-out skirmishing methods; and Mrs. Mesomelas, on three legs and with the bill for the other to be settled, helped him.

It was very difficult, in the tropic dust, to follow what exactly happened next.  For the next few minutes black-back was here, there, and everywhere, leaping and dodging in and out like a lambent flame.  The human eye could scarcely follow him, but the human ear could hear plainly the nasty, dog-like snarling and the snap of teeth.
