“That bushman is a serviceable little fellow,” observed Mr Vincent. “I have often seen both the tubers and the melons, but I have never found them before in this part of the desert. The latter seldom last long after the rains, as not only do the natives of the desert collect them, but elephants, and rhinoceroses, and even lions and hyenas, come from a distance to devour them. It was probably in consequence of the arid character of the surrounding desert that the patch to which the bushman took you has escaped a visit from them.”

Martin begged that he might be allowed to reward his guide, who seemed well satisfied with an axe and several other useful articles, as well as some beads which he received.

“You should have waited till they can be of no further use before giving them presents,” observed his father. “Depend upon it, they will be off before long; and it Masiko, as I suspect, has lost his way, we shall be in no small difficulty.”

Martin hoped that their new friends would prove faithful, though as the waggon moved on during the afternoon they said something which made him suspect that their wanderings did not extend much further to the north. They, however, accompanied the caravan to the end of the day’s journey; but when morning broke they were nowhere to be seen, they had gone off, as the old woman had before, without being observed by the watch, who had probably been slumbering at the time.

Here a whole day was spent, that both men and beasts might obtain that rest they so much required.

Again the caravan was on the move. Masiko urged that they should push on as rapidly as possible, for he could not say when they might next reach water. But a small supply remained in their skin bottles.

The horses and cattle were again suffering greatly. First one of the oxen in the team fell, then another, and another; and though their places were supplied by the spare animals, the waggon continued to move on at an unusually slow pace.

The last drop of water in the skins was exhausted, and even some of the men accustomed to desert travelling declared they could go no further.

The sun was striking down on their heads with intense force. The men’s lips were parched, their eyes bloodshot. The animals moved on with open mouths, lowing piteously in their sufferings. The trader began to fear that the whole party would knock up. In that case, his only hope of saving his own life and that of his son would be to abandon them with his waggon and goods, and to gallop forward, on the chance of finding water.

They had ridden some distance ahead of the caravan, when Martin, who was a short way in front of his father, shouted out, “Water! water!” pointing as he spoke to a beautiful lake in the distance, its waters, curled by the breeze, shining with intense lustre in the bright sun. On the further shore trees were seen reflected clearly on the surface, while among them appeared a number of elephants cooling themselves by throwing water over their bodies.
