The Mission by Frederick Marryat

There was no alarm during the night, and the next morning they yoked the oxen and changed their course to the northward. The whole of the cattle had been led down to the river to drink, and allowed two hours to feed before they started; for they were about to pass through a sterile country of more than sixty miles, where they did not expect to find either pasturage or water. They had not left the river more than three miles behind them, when the landscape changed its appearance. As far as the eye could scan the horizon, all vestiges of trees had disappeared, and now the ground was covered with low stunted bushes and large stones. Here and there were to be seen small groups of animals, the most common of which were the quaggas. As our travelers were in the advance, they started six or seven ostriches which had been sitting, and a ball from the Major's rifle brought one to the ground, the others running off at a velocity that the fastest horse could scarcely have surpassed.

"That was a good shot, Major," said Alexander.
