He galloped, but still the limping creature managed, not only to keep a start, but even to increase its lead. In a while it squatted, as if it had reached the end of its tether, and Guy thought now surely it was his. It was not so, however. As he approached within four hundred yards the great bird rose and pursued its way, stumbling, staggering occasionally, as if it would fall on its head, and flapping its wings, plainly in great distress. It was very annoying that, notwithstanding its apparent sickness, the bird could yet manage as it did to keep going. Mile after mile went by, and still the ostrich stumbled along, just beyond reasonable shooting distance. Once again, having gained a fresh lead, in response to a long spurt on the part of Guy, it sat down again; and once more Guy was most provokingly baulked of what he now looked upon as his legitimate booty--those magnificent plumes that waved and dangled so annoyingly, just beyond reach of his trusty Martini. The lad had now become downright angry. That bird should be his, if he had to ride till evening; and so, about five hundred yards still separating them, the hunted and the hunter moved swiftly across the plain for another mile. Three o’clock went by--four o’clock--surely the bird would soon give in! But now it was running quite differently. There was no trace of the falterings and stumblings that he had so long noticed. The cock was apparently quite recovered, and running as strongly and as straight as had its mate. Then suddenly there flashed upon Guy’s mind what had happened. The creature had been playing the fool with him all this time. It had simulated lameness and sickness, just as will a plover or a partridge, merely to decoy him away from its nest, which he had by a lucky chance ridden by and discovered. Guy smiled grimly to himself as the cleverness of the whole ruse was borne in upon him. Nevertheless, he was wild with vexation; and setting his teeth, he said to himself very softly that he would make it hot for the shamming bird yet. And, indeed, he did so. He was now full twenty miles from camp; hills and kopjes rose not very far in front of him--hills which, now ruddy brown and plain to see, looked four hours ago blue in the distance. His pony was a good one, and in first-rate condition. It was not by any means at the end of its resources, and Guy called upon it for one more long and sustained effort. Two more miles were past. Then Guy, to his joy, discovered that the ostrich was really coming back to him. The long and persistent chase under the hot sun had at last told upon it. He had certainly gained one hundred and fifty yards in the last hour.
