The ostrich has decidedly the best of it, for Plata, though he struggles gamely, does not like the uphill work, and at every stride loses ground. There is another fire on the hill above, but it lies too much to the left to attract the bird’s attention, who has evidently a safe line of escape in view in that direction. On, on we press; on, on flies the ostrich; bravely and gamely struggles in its wake poor Plata. “Can he stay?” I cry to Gregorio, who smiles and nods his head. He is right, the dog can stay, for hardly have the words left my lips when, with a tremendous effort, he puts on a spurt, and races up alongside the ostrich. Once more the bird points for the plain; he is beginning to falter, but he is great and strong, and is not beaten yet. It will take all Plata’s time and cunning to pull that magnificent bird to the ground, and it will be a long fierce struggle ere the gallant creature yields up his life. Unconscious of anything but the exciting chase before me, I am suddenly disagreeably reminded that there _is_ such a thing as caution, and necessity to look where you are going to, for, putting his foot in an unusually deep tuca-tuca hole, my little horse comes with a crash upon his head, and turns completely over on his back, burying me beneath him in a hopeless muddle. Fortunately, beyond a shaking, I am unhurt, and remounting, endeavor to rejoin the now somewhat distant chase. The ostrich, Gregorio, and the dog have reached the plain, and as I gallop quickly down the hill I can see that the bird has begun doubling. This is a sure sign of fatigue, and shows that the ostrich’s strength is beginning to fail him. Nevertheless it is a matter of no small difficulty for one dog to secure his prey, even at this juncture, as he can not turn and twist about as rapidly as the ostrich. At each double the bird shoots far ahead of his pursuer, and gains a considerable advantage. Away across the plain the two animals fly, whilst I and Gregorio press eagerly in their wake. The excitement grows every moment more intense, and I watch the close struggle going on with the keenest interest. Suddenly the stride of the bird grows slower, his doubles become more frequent, showers of feathers fly in every direction as Plata seizes him by the tail, which comes away in his mouth. In another moment the dog has him by the throat, and for a few minutes nothing can be distinguished but a gray struggling heap. Then Gregorio dashes forward and throws himself off his horse, breaks the bird’s neck, and when I arrive upon the scene the struggle is over. The run had lasted for twenty-five minutes.
