The third, and at last successful, effort to reach Sebituane was made in April, 1851. Livingstone was again accompanied by his family, and by Mr. Oswell. He left Kolobeng with the intention not to return, at least not immediately, but to settle with his family in such a spot as might be found advantageous, in the hilly region, of whose existence he was assured. They found the desert drier than ever, no rain having fallen throughout an immense extent of territory. To the kindness of Mr. Oswell the party was indebted for most valuable assistance in procuring water, wells having been dug or cleared by his people beforehand at various places, and at one place at the hazard of Mr. Oswell's life, under an attack from an infuriated lioness. In his private Journal, and in his letters to home, Livingstone again and again acknowledges with deepest gratitude the numberless acts of kindness done by Mr. Oswell to him and his family, and often adds the prayer that God would reward him, and of His grace give him the highest of all blessings. "Though I cannot repay, I may record with gratitude his kindness, so that, if spared to look upon these, my private memoranda, in future years, proper emotions may ascend to Him who inclined his heart to show so much friendship." The party followed the old route, around the bed of the Zouga, then crossed a piece of the driest desert they had ever seen, with not an insect or a bird to break the stillness. On the third day a bird chirped in a bush, when the dog began to bark! Shobo, their guide, a Bushman, lost his way, and for four days they were absolutely without water. In his _Missionary Travels_, Livingstone records quietly, as was his wont his terrible anxiety about his children. "The supply of water in the wagons had been wasted by one of our servants, and by the afternoon only a small portion remained for the children. This was a bitterly anxious night; and next morning, the less there was of water, the more thirsty the little rogues became. The idea of their perishing before our eyes was terrible; it would almost have been a relief to me to have been reproached with being the entire cause of the catastrophe, but not one syllable of upbraiding was uttered by their mother, though the tearful eye told the agony within. In the afternoon of the fifth day, to our inexpressible relief, some of the men returned with a supply of that fluid of which we had never before felt the true value." "No one," he remarks in his Journal, "knows the value of water till be is deprived of it. We never need any spirits to qualify it, or prevent an immense draught of it from doing us harm. I have drunk water swarming with insects, thick with mud, putrid from other mixtures, and no stinted draughts of it either, yet never felt any inconvenience from it."
