He looked graver than usual, and not without reason. The heat was very great, and we had a wide extent of country before us, the soil consisting of light-coloured soft sand, which appeared incapable of producing any green thing for the support of animals. Pass it, however, we must, as it extended right across our path to the south, far away to the east, from the very coast of the Atlantic. Notwithstanding this, our party were in good spirits, from feeling that we were now making steady progress towards home. "We have encountered so many dangers, and escaped them, that we should not mistrust the willingness of the kind hand of Providence to protect us to the end of our journey," observed Kate. Her calm confidence gave us all courage, and we resolved not to allow any anticipation of evil to oppress us. Kate had never relaxed in her resolution to instruct Bella under all difficulties, and the greater part of the day they sat in the waggon with their books before them, or their work in their hands, labouring away as diligently as they would have done in their home in the colony. Leo and Natty were far more idle, though they occasionally took their seats near the young ladies, and either read to them, or listened to their reading. The Bible was their chief book, and happily its stores are inexhaustible. The other works they had read over and over again, till they declared that they could no longer look at them with patience. The heat was so great, that we were compelled to camp during the middle of the day, finding that we could make more progress by travelling early in the morning and again in the evening. We had travelled on since daylight, when a group of trees, which are found here and there even on the desert, gladdened our eyes. We unyoked our weary oxen beneath them, and sought such shelter as their branches would afford; but not a drop or sign of water was to be seen round them. It seemed surprising how they could exist in that arid spot. Fires were lighted to cook the remnant of our provisions, though they also had fallen very short. We were seated at our meal, when Stanley started up, exclaiming, "We must have some of those fellows! Who will come with me?" He pointed eastward--the quarter whence the wind blew--and there I saw, moving slowly over the plain, and cropping the scanty herbage as they went, a large herd of antelopes. "I will," I said, "if I can have a horse." "You shall have mine," said Senhor Silva. "I must go with you!" exclaimed Donald Fraser, gulping down the largest part of the contents of an ostrich egg.
