The words somewhat relieved my fears, and throwing myself from the ox, I knelt down by his side. My first care was to pour some water down his throat, then to bathe his temples; to treat him, indeed, as I had Natty under similar circumstances. I cannot express my thankfulness when I saw him at length open his eyes. He gazed at me with a look of surprise, but he was still too weak to speak. He pointed to his lips, and I gave him more water. It was necessary to get him at once into the shade, for, exposed to the hot sun, it was scarcely possible that he could regain his strength. Mango accordingly lifted him up on the ox's back, and I supporting him in my arms, he urged the animal on towards a wood we saw in the distance. Leo was still too weak to speak, but he recognised me, and a grateful look lighted up his eyes as he gazed at my face. As I thought he might understand me, I briefly narrated some of my adventures in search of him, of course not telling him my anxiety about his sisters and brothers. How thankful I felt that I had come in time to save him, for it was evident that he would not have survived many hours lying out on the exposed plain. I was now doubtful whether we should proceed on in the same course we had been steering, or turn away to the west in search of Kabomba, where, I felt sure, he would be well taken care of. I should have to go there at all events for Natty, even if we could gain certain tidings that our friends were further south. Presently Leo's lips moved, and I heard him whispering, "On! on as before! You will find them, I am sure!" This decided me. Still, I resolved to rest at the nearest wood we could reach. I was thankful when at length we arrived at one--a little oasis in the desert. What was still more satisfactory, within it appeared a small pool, a bright stream rushing out of the bank on its side. We had tethered the ox. While Mango sat by Leo's side bathing his temples and wetting his lips, I was busily employed in collecting wood for our hut. Suddenly the sound of animals rushing across the plain reached my ears. I looked up, and saw a troop of giraffes galloping at full speed, and, closely following them, two horsemen. On they dashed! Shouting at the top of my voice, I called again and again. I rushed to the ox, in the vain hope of overtaking them. Even at that distance I fancied I recognised Stanley, though his companion's figure I did not know. Just as I was about to mount, there came tearing after them, as if in pursuit, a large herd of buffaloes, among which appeared several huge rhinoceroses. It seemed as if they were in pursuit of the horsemen. Another herd of buffaloes came out of the wood opposite, and stopping, gazed a few moments before joining the chase. The whole passed by like creatures in a dream. I saw at once that it would be impossible to catch up the horsemen; besides which, I should have run a great chance of being gored
