Christmas time is about the hottest season of the year in South Africa, unless heavy rains happen to be falling, and at the time of which I am writing the heat was simply terrific. The country around us was an absolutely dead level in all directions, everywhere clothed with a sparse covering of low thorny bushes, whose little grey-green leaves and hard black twigs, over which little hook-shaped thorns are profusely scattered, afforded but little protection from the cruel sun. Early in the day the sand became so hot that it was quite impossible to keep the palm of one's hand upon it for more than a few seconds at a time, nor was it possible to hold one's hand on any piece of iron exposed to the sun's rays. The sand itself was so deep and soft, that our heavy bullock waggons sank in it to a depth of several inches, over the felloes of the wheels, in fact; and as our long caravan moved slowly and painfully forwards, both bullocks and waggons were almost hidden from sight in a thick cloud of fine dust which rose from the trampled ground into the still hot air. When the sun set the relief was immense, but still the heat thrown up from the scorched sand was very great, and it was only for one short hour between dawn and sunrise that the temperature became pleasantly cool.

It was about four o'clock on the afternoon of December 23 that we finally left Tlakani, after having carefully filled our water-casks and given all the bullocks and horses a good drink. At sundown we outspanned, made a hasty meal of dried eland meat roasted on the ashes, washed down with a cup of tea, and then inspanned again. All that night we trekked on with only two short intervals of rest, and when day broke on, the morning of December 24, our oxen had done ten hours' actual pulling through the heavy sand and covered some fifteen miles since leaving Tlakani. All this day we travelled slowly onwards through the frightful heat, giving the bullocks an hour's rest after every two hours' pull. The terrific heat of the cruel pitiless sun told upon the straining oxen very rapidly, for it must be remembered that nothing but steady hard pulling by every member of each span, all pulling in unison, could move the heavy waggons through the deep sand, and nothing made of flesh and blood could work very long in such a temperature without drinking.

Towards the close of the long day it became a pitiful sight to look at the poor oxen, as they toiled slowly and painfully along, with lowered heads and tongues hanging from their gasping mouths. The hot air they breathed was full of fiery dust, which rose in clouds from their feet and hung suspended in the breathless atmosphere long after the last waggon had passed. This hot dust no doubt very much aggravated the terrible thirst from which our bullocks were now suffering, and kept them continually gasping and coughing.

At last the dreadful sun turned blood-red as it neared the western horizon, and then soon sank from view behind the interminable landscape of stunted thorn bushes. When outspanned during the day, the bullocks had made no attempt to feed, but had only stood about in clusters amongst the shadeless thorn scrub; I was in hopes, however, that they would graze a little at sunset, albeit the grass was scorched and scant. But they were too parched to do so; and so, hungry, weary, and terribly thirsty, the poor brutes were once more yoked to the heavy waggons just as the short twilight of the early tropic night was giving place to a bright moonlight, for it wanted but a couple of days to full moon. The whole of this second night we travelled slowly southwards, with short intervals of rest.

I kept awake once more throughout the night, in order to time the periods of travel and the intervals of rest. As we were four Europeans, we might have kept awake turn and turn about, and turned in for a sleep in one of the waggons when not on duty; but when travelling through the desert I am always too anxious to be able to sleep, whilst making a push from one water to another, and always make a point of timing the treks myself, and keeping the waggon-drivers and leaders up to the mark; for these latter naturally get worn out during such journeys, and often are so tired that when a halt is called, they just throw themselves down where they stand and lie there like logs till it is time to move on again.

During the night we passed the deep limestone well and shallow pan of Inkowani, both of which were perfectly dry, and presently Christmas Day 1879 dawned upon us, and the cruel sun was soon once more shining over the desolate wilderness around us. By this time it had become evident that our bullocks could not possibly pull the heavy waggons much farther. One or other of them was constantly lying down, and had to be mercilessly beaten or its tail twisted or bitten before it could be induced to get up again and struggle on a little farther. Although the waggons of our Bamangwato friends were much less heavily laden than ours, their bullocks were much inferior, and on the whole in quite as sorry a plight.

About ten o'clock it became impossible to get the waggons along at all, and we had to give up the idea of reaching the pools of Mahakabi, from which we were only about six miles distant, with them, as we had hoped to have done. We therefore outspanned, and prepared to drive all our cattle and horses to the water, let them have a good drink and feed there, and return to fetch the waggons in the afternoon. Collison was not very well, so he and Sell remained with the waggons, whilst Miller and I—both of us mounted—and all our coloured boys, with the exception of the waggon-drivers, accompanied Tinkarn and his people to Mahakabi, taking all our cattle, horses, and dogs with us. Tinkarn, I think, only left a couple of boys to look after the five waggons belonging to his people. I let him start first with all his people and their troop of cattle, Miller and I following with our own herd, driven by our own boys, about a quarter of an hour or twenty minutes later. I rode my own favourite shooting horse "Bob," and led Collison's best nag "Big Bles," his after-rider, a Mangwato boy, named Dick, being mounted on his second horse. I had had a cup of coffee when we outspanned just before daylight, but had eaten nothing since the previous evening, and had not even tied a piece of "biltong" on my saddle, when leaving the waggons with the oxen, as I had hoped to get back again before sundown, and was besides too full of anxiety to think much about food just then.

Although the bullocks were unable to drag our heavy waggons any farther through the deep sand, they stepped out briskly enough along the road when unencumbered, and evidently knew that they were being taken to water. We were just approaching the first of the two pools of Mahakabi, and could see the cattle of our Mangwato friends standing round about it, when I saw Tinkarn coming riding back to meet me. "Metsi utin?" ("Is there water?"), I asked. "Metsi haio" ("There is no water"), he answered; almost immediately adding, "But we shall find water; I have two Bushmen here who will show us water." From the appearance of the grass, it was evident that a heavy shower of rain must have fallen over this part of the country about a month before our arrival, and Tinkarn told me that there must then have been a good supply of water in the Mahakabi vleys, which, however, had been very rapidly sucked up by the intense heat which had lately prevailed. When the Mangwatos' troop of cattle first reached the nearest and biggest vley, there was still a little water in it, but the thirsty beasts just rushed into the shallow pool, and of course soon trampled it into mud. Two Bushmen, however, had been found at the water, who, of course, knew Tinkarn and feared him, as one of Khama's most influential headmen, and these savages reported that heavy rain had fallen farther to the east during the last moon, and thought that a certain vley they knew of would probably still have some water in it. If there should prove to be no water there, said they, they would guide us to the place where the road from Shoshong to Pandamatenka crossed the Luali river.

It was now past midday, and the heat intense. Our horses, as well as the oxen, had been nearly forty-eight hours without drinking, but as they had done no work during that time, they were not suffering like the latter animals. However, I did not like to go away with the cattle, and perhaps have to take them right through to Luali, without letting Collison know what had happened, so I sent Miller back to the waggons, telling him to give the horse he was riding a few pannikins of water as soon as he got there, as our two largest casks had, I knew, been scarcely touched. Should the vley spoken of by the Bushmen prove to contain a good supply of water, I told Miller I would rest the oxen there until after midday on the 26th, and drive them back to the waggons, after they had had a good drink, on the afternoon of that day, in time to start for Klabala the same evening. Should I not turn up by that time, however, I told him not to expect me for at least another twenty-four hours, as he would then know I had had to go on to Luali.
