Although the construction of this ostrich excited much amusement amongst the men, and although I noticed a good deal of grinning and chuckling amongst them as I went out, they were very greatly astonished at the result. From the camp I could see two _G. Grantii_ standing out in the open about a mile off. Within half a mile of them and on my left there was a slight rise in the ground, which I took advantage of, and thus got within about 600 yards of them before donning the ostrich. Directly I appeared over the top of the rise the gazelles saw me, but I soon allayed their suspicions by pretending to feed and pick about. I then went on, stopping every now and again ‘to feed,’ and without the least trouble walked up to within 90 yards of them, and got both with a right and left shot To show how successful the imitation was, I passed two wart-hogs within 60 yards on my right and a couple of greater bustards (_Otis kori_) within 40 yards on my left, and none of them showed the slightest signs of fear until after I had gone by them, when the wind exposed the deception. The next day I approached a large herd of some thirty-five _G. Grantii_, got within 40 yards, and killed the best buck, a magnificent beast, in spite of three or four does which stood within 25 yards of me. After the shot, instead of revealing myself, I picked up the neck of the ostrich, which I had been obliged to drop in order to take the shot, and rushed after the retreating herd. When they stopped after going about 600 yards, the feigned alarm of the ostrich was apparently so real that they allowed me to run straight up to within 60 yards of them. However, I was so pumped from the run, and tired by the first long walk up to the herd in a cramped and stooping position, trying to assimilate my height to that of an ostrich’s body, that I was very unsteady, and a shot at the next best buck missed him clean, and away went the herd.
