Far to the south-west the herd of springbuck was now clearly visible. Most of them were quietly grazing in the mild sunshine. Now and then a few detached themselves from the main body and, one behind the other, bounded away for a few hundred yards on a course curved like the blade of a scimitar—“pronking” with the sheer joy of unspoilt life. After such an excursion they would rejoin the others and go on feeding. And I had come to... But if I had let Jekyll climb to my crupper Andries would have got no shooting. The herd was a small one; it did not number more than about six hundred. It was curious that these bucks had not joined in the general migration eastward towards where the lightning had flashed its message of rain a few nights previously.
The springbucks had not seen us as yet, for we were still about two miles distant from them. The eyes of these animals seem to be specialised to a definite range as the ear is tuned to a certain gamut of sound. I will endeavour to explain what is meant by this. They do not seem to notice anything at a greater distance than about fifteen hundred yards. Conversely, should you be lying in ambush and the bucks come to within fifty yards of you, they would evince far less alarm if you shewed yourself than on seeing you at a distance of from two to three hundred yards.
This can easily be accounted for. The springbuck has always spent its life in an environment of menace, but as conditions change the nature of the menace changes with them. Formerly the danger-zone for these creatures was that from which the lion, the leopard or the wild dog could spring; it was only surprise at close quarters that the springbuck had to guard against. Given a few seconds’ notice of the approach of an enemy, this creature’s unsurpassed fleetness enabled it to laugh at danger. This laughter is still expressed in the manner in which a small herd of springbuck will circle round and round a pursuing dog that is not especially swift—as porpoises sometimes circle around a moving ship.
We know from accounts left by the very old hunters that in early days, when the killing range of a bullet was little more than a hundred yards, springbuck would graze with apparent unconcern until approached to within about that distance. But with the disappearance of the larger carnivora before firearms, and the increase in the range of the rifle, a wider danger-zone has been created, while the danger of an enemy at close quarters has practically disappeared. The width of the danger-zone has gone on increasing with the longer range of the rifle.
Wild animals are quick to learn and to unlearn—which is not quite the same as to forget. Thus the springbuck has ceased to dread the springing enemy, the creature of teeth and claws that used to lie in ambush; in fact he never contemplates the contingency of any enemy at close quarters, and on the rare occasions when he meets one, the experience appears to fill him with surprise rather than alarm.
The distance between us and the herd had decreased to a little over two thousand yards, so I detached Hendrick and instructed him to alter his course to the left and endeavour to edge round the still unsuspecting animals. The object was to stampede the herd so that it would pass me on my right and head towards where Andries lay in ambush. Bucephalus and Hendrick loomed immense and black against the background of yellow shocks, but they were apparently unobserved by the game, for the latter still grazed and “pronked” about as though they had the whole desert to themselves,—as though no entangling web were being drawn about them.
Hendrick had reached the limit of his arc; then the springbuck marked him and evidently realised that there was danger. Apprehension touched them; a quiver ran through the herd; they lifted their heads and gazed; they moved to and fro. So far it was not fear that they felt; for they knew their own fleetness and had trust in it. Then, suddenly, terror seemed to strike them like a blast, for as dead leaves are caught by a wind-eddy and whirled in a spiral, these imponderable-seeming, ethereal desert creatures swerved over an area resembling in form the sweep of a fan, and then streamed forth like a handful of white rose-petals before a gale.
Why is it, I wonder, that during the forenoon springbuck in the desert appear to be white? For this is literally the case; these animals seemed to be as white as snow, as imponderable as thistledown. The fawn-tint of their necks and flanks, the broad, brown patches on their sides, the black, lyre-formed horns,—all were drowned in the milky foam of the dorsal manes. These were expanded laterally to their fullest extent; each long silvery hair stood erect and quivering.
The creatures’ heads were depressed almost to the level of their feet. With backs deeply arched they bounded over the face of the desert like so many alabaster discs—mingling, separating and re-combining in a tracery of flying arabesques. They had adopted the attitude and movement usual to their kind in moments of sudden terror or delight. Surely their flight was the highest expression of grace revealed by animated nature in motion. It was a soundless melody; a symphony for the eye.
The torrent was streaming to my right, straight for Andries. Hendrick thundered behind,—a black Centaur-monstrosity. How terrible he must have appeared to the fugitives. I wished Hendrick then would trend to his right, for if the springbuck had swerved towards Kanxas and caught sight of the wagon, they would have doubled on their tracks and made for the depths of the desert. My object was to hold them on the course they were following for as long as possible. Ha! they must have sighted the wagon, for they wheeled to their right and attempted to escape past me, about three thousand yards on my side of where Andries lay waiting for his shot. The terror of death was upon them; their manes were down—hidden in the constricted dorsal tract. The eye could hardly follow the movement of their limbs; distance died beneath the lightning of their feet.
