odd sight it was. There was not only the misty swarm of the insects to gaze upon. The air above them was filled with birds – strange birds and of many kinds. On slow, silent wing soared the brown “oricou,” the largest of Africa’s vultures; and along with him the yellow “chasse fiente,” the vulture of Kolbé. There swept the bearded “lamvanger,” on broad extended wings. There shrieked the great “Caffre eagle,” and side by side with him the short-tailed and singular “bateleur.” There, too, were hawks of different sizes and colours, and kites cutting through the air, and crows and ravens, and many species of insectivora. But far more numerous than all the rest could be seen the little springhaan-vogel, a speckled bird of nearly the size and form of a swallow. Myriads of these darkened the air above – hundreds of them continually shooting down among the insects, and soaring up again, each with a victim in its beak. “Locust-vultures” are these creatures named, though not vultures in kind. They feed exclusively on these insects, and are never seen where the locusts are not. They follow them through all their migrations, building their nests, and rearing their young, in the midst of their prey!
It was, indeed, a curious sight to look upon, that swarm of winged insects, and their numerous and varied enemies; and all stood gazing upon it with feelings of wonder. Still the living cloud approached no nearer, and the hopes of Von Bloom continued to rise.
The swarm kept extending to the south – in fact, it now stretched along the whole western horizon; and all noticed that it was gradually getting lower down – that is, its top edge was sinking in the heavens. Were the locusts passing off to the west? No.
“Da am goin’ roost for da nacht – now we’ll get ’em in bagfull,” said Swartboy, with a pleased look; for Swartboy was a regular locust-eater, as fond of them as either eagle or kite, – ay, as the “springhaan-vogel” itself.
It was as Swartboy had stated. The swarm was actually settling down on the plain.
“Can’t fly without sun,” continued the Bushman. “Too cold now. Dey go dead till da mornin.”
And so it was. The sun had set. The cool breeze weakened the wings of the insect travellers, and they were compelled to make halt for the night upon the trees, bushes, and grass.
In a few minutes the dark mist that had hid the blue rim of the sky, was seen no more; but the distant plain looked as if a fire had swept over it. It was thickly covered with the bodies of the insects, that gave it a blackened appearance, as far as the eye could reach.
The attendant birds, perceiving the approach of night, screamed for awhile, and then scattered away through the heavens. Some perched upon the rocks, while others went to roost among the low thickets of mimosa; and now for a short interval both earth and air were silent.
Von Bloom now bethought him of his cattle. Their forms were seen afar off in the midst of the locust-covered plain.
“Let ’em feed um little while, baas,” suggested Swartboy.
“On what?” inquired his master. “Don’t you see the grass is covered!”
“On de springhaan demself, baas,” replied the Bushman; “good for fatten big ox – better dan grass – ya, better dan mealies.”
But it was too late to leave the cattle longer out upon the plain. The lions would soon be abroad – the sooner because of the locusts, for the king of the beasts does not disdain to fill his royal stomach with these insects – when he can find them.
Von Bloom saw the necessity of bringing his cattle at once to their kraal.
A third horse was saddled, which the field-cornet himself mounted, and rode off, followed by Hendrik and Swartboy.
On approaching the locusts they beheld a singular sight. The ground was covered with these reddish-brown creatures, in some spots to the depth of several inches. What bushes there were were clustered with them, – all over the leaves and branches, as if swarms of bees had settled upon them. Not a leaf or blade of grass that was not covered with their bodies!
They moved not, but remained silent, as if torpid or asleep. The cold of the evening had deprived them of the power of flight.
What was strangest of all to the eyes of Von Bloom and Hendrik, was the conduct of their own horses and cattle. These were some distance out in the midst of the sleeping host; but instead of being alarmed at their odd situation, they were greedily gathering up the insects in mouthfuls, and crunching them as though they had been corn!
It was with some difficulty that they could be driven off; but the roar of a lion, that was just then heard over the plain, and the repeated application of Swartboy’s jambok, rendered them more tractable, and at length they suffered themselves to be driven home, and lodged within their kraals.
Swartboy had provided himself with a bag, which he carried back full of locusts.
It was observed that in collecting the insects into the bag, he acted with some caution, handling them very gingerly, as if he was afraid of them. It was not them he feared, but snakes, which upon such occasions are very plenteous, and very much to be dreaded – as the Bushman from experience well knew.
Chapter Four.
A talk about Locusts
It was a night of anxiety in the kraal of the field-cornet. Should the wind veer round to the west, to a certainty the locusts would cover his land in the morning, and the result would be the total destruction of his crops. Perhaps worse than that. Perhaps the whole vegetation around – for fifty miles or more – might be destroyed; and then how would his cattle be fed? It would be no easy matter even to save their lives. They might perish before he could drive them to any other pasturage!
Such a thing was by no means uncommon or improbable. In the history of the Cape colony many a boor had lost his flocks in this very way. No wonder there was anxiety that night in the kraal of the field-cornet.
At intervals Von Bloom went out to ascertain whether there was any change in the wind. Up to a late hour he could perceive none. A gentle breeze still blew from the north – from the great Kalihari desert – whence, no doubt, the locusts had come. The moon was bright, and her light gleamed over the host of insects that darkly covered the plain. The roar of the lion could be heard mingling with the shrill scream of the jackal and the maniac laugh of the hyena. All these beasts, and many more, were enjoying a plenteous repast.
Perceiving no change in the wind, Von Bloom became less uneasy, and they all conversed freely about the locusts. Swartboy took a leading part in this conversation, as he was better acquainted with the subject than any of them. It was far from being the first flight of locusts Swartboy had seen, and many a bushel of them had he eaten. It was natural to suppose, therefore, that he knew a good deal about them.
He knew not whence they came. That was a point about which Swartboy had never troubled himself. The learned Hans offered an explanation of their origin.
“They come from the desert,” said he. “The eggs from which they are produced, are deposited in the sands or dust; where they lie until rain falls, and causes the herbage to spring up. Then the locusts are hatched, and in their first stage are supported upon this herbage. When it becomes exhausted, they are compelled to go in search of food. Hence these ‘migrations,’ as they are called.”
This explanation seemed clear enough.
“Now I have heard,” said Hendrik, “of farmers kindling fires around their crops to keep off the locusts. I can’t see how fires would keep them off – not even if
