My next attempt to bag a rhino took place some months later, on the banks of the Sabaki, and was scarcely more successful. I had come down from Tsavo in the afternoon, accompanied by Mahina, and finding a likely tree, within a few yards of the river and with fresh footprints under it, I at once decided to take up my position for the night in its branches. Mahina preferred to sit where he could take a comfortable nap, and wedged himself in a fork of the tree some little way below me, but still some eight or ten feet from the ground. It was a calm and perfect night, such as can be seen only in the tropics; everything looked mysteriously beautiful in the glorious moonlight, and stood out like a picture looked at through a stereoscope. From my perch among the branches I watched first a water-buck come to drink in the river; then a bush-buck; later, a tiny paa emerged from the bushes and paused at every step with one graceful forefoot poised in the air--thoroughly on the alert and looking round carefully and nervously for any trace of a possible enemy. At length it reached the brink of the river in safety, and stooped to drink. Just then I saw a jackal come up on its trail and begin carefully to stalk it, not even rustling a fallen leaf in its stealthy advance on the poor little antelope. All of a sudden, however, the jackal stopped dead for a second, and then made off out of sight as fast as ever he could go. I looked round to discover the cause of this hurried exit, and to my surprise saw a large and very beautiful leopard crouching down and moving noiselessly in the direction of our tree. At first I thought it must be stalking some animal on the ground below us, but I soon realised that it was Mahina that the brute was intent on. Whether, if left to himself, the leopard would actually have made a spring at my sleeping gun-bearer, I do not know; but I had no intention of letting him have a chance of even attempting this, so I cautiously raised my rifle and levelled it at him. Absolutely noiseless as I was in doing this, he noticed it--possibly a glint of moonlight on the barrel caught his eye--and immediately disappeared into the bush before I could get in a shot. I at once woke Mahina and made him come up to more secure quarters beside me.
