The joyous countenances of all once more wore a sad expression, and it was no longer with curiosity that they gazed upon the distant cloud, that so suddenly had clouded their joy.
Von Bloom had good cause for dread. Should the swarm come on, and settle upon his fields, farewell to his prospects of a harvest. They would strip the verdure from his whole farm in a twinkling. They would leave neither seed, nor leaf, nor stalk behind them.
All stood watching the flight with painful emotions. The swarm was still a full half-mile distant. They appeared to be coming no nearer,—good!
A ray of hope entered the mind of the field-cornet. He took off his broad felt hat, and held it up to the full stretch of his arm. The wind was blowing from the north, and the swarm was directly to the west of the kraal. The cloud of locusts had approached from the north, as they almost invariably do in the southern parts of Africa.
“Yes,” said Hendrik, who having been in their midst could tell what way they were drifting, “they came down upon us from a northerly direction. When we headed our horses homewards, we soon galloped out from them, and they did not appear to fly after us; I am sure they were passing southwards.”
Von Bloom entertained hopes that as none appeared due north of the kraal, the swarm might pass on without extending to the borders of his farm. He knew that they usually followed the direction of the wind. Unless the wind changed they would not swerve from their course.
He continued to observe them anxiously. He saw that the selvedge of the cloud came no nearer. His hopes rose. His countenance grew brighter. The children noticed this and were glad, but said nothing. All stood silently watching.
An 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.
