On we tramped silently as shades through the night and in the heavy sand. The karoo bushes caught our shins and retarded us, and the sand got into our veldtschoons and Good's shooting-boots, so that every few miles we had to stop and empty them; but still the night was fairly cool, though the atmosphere was thick and heavy, giving a sort of creamy feel to the air, and we made fair progress. It was very still and lonely there in the desert, oppressively so indeed. Good felt this, and once began to whistle the "Girl I left behind me," but the notes sounded lugubrious in that vast place, and he gave it up. Shortly afterwards a little incident occurred which, though it made us jump at the time, gave rise to a laugh. Good, as the holder of the compass, which, being a sailor, of course he thoroughly understood, was leading, and we were toiling along in single file behind him, when suddenly we heard the sound of an exclamation, and he vanished. Next second there arose all round us a most extraordinary hubbub, snorts, groans, wild sounds of rushing feet. In the faint light,-too; we could descry dim, galloping forms half hidden by wreaths of sand. The natives threw down their loads and prepared to bolt, but, remembering that there was nowhere to bolt to, cast themselves upon the ground and howled out that it was the devil. As for Sir Henry and myself, we stood amazed; nor was our amazement lessened when we perceived the form of Good careering off in the direction of the mountains, apparently mounted on the back of a horse and halloing like mad. In another second he threw up his arms, and we heard him come to the earth with a thud. Then I saw what had happened: we had stumbled right on to a herd of sleeping quagga, on to the back of one of which Good had actually fallen, and the brute had naturally enough got up and made off with him. Singing out to the others that it was all right, I ran towards Good, much afraid lest he should be hurt, but to my great relief found him sitting in the sand, his eye-glass still fixed firmly in his eye, rather shaken and very much startled, but not in any way injured.

After this we travelled on without any further misadventure till after one o'clock, when we called a halt, and having drunk a little water, not much, for water was precious, and rested for half an hour, started on again.

On, on we went till at last the east began to blush like the cheek of a girl. Then there came faint rays of primrose light that changed presently to golden bars, through which the dawn glided out across the desert. The stars grew pale and paler still till at last they vanished; the golden moon waxed wan, and her mountain ridges stood out clear against her sickly face like the bones on the face of a dying man; then came spear upon spear of glorious light flashing far away across the boundless wilderness, piercing and firing the veils of mist till the desert was draped in a tremulous golden glow, and it was day.

Still we did not halt, though by this time we should have been glad. enough to do so, for We knew that when once the sun was fully up it would be almost impossible for us to travel in it. At length, about six o'clock, we spied a little pile of rocks rising out of the plain, and to this we dragged ourselves. As luck would have it, here we found an overhanging slab of rock carpeted beneath with smooth sand, which afforded a most grateful shelter from the heat. Underneath this we crept, and having drank some water each and eaten a bit of biltong, we lay down and were soon sound asleep.

It was three o'clock in the afternoon before we woke, to find our three bearers preparing to return. They had already had enough of the desert, and no number of knives would have tempted them to come a step farther. So we had a hearty drink, and, having emptied our water-bottles, filled them up again from the gourds they had brought with them, and then watched them depart on their twenty miles' tramp home.

At half-past four we also started on. It was lonely and desolate work, for, with the exception of a few ostriches, there was not a single living creature to be seen on all the vast expanse of sandy plain. It was evidently too dry for game, and, with the exception of a deadly looking cobra or two, we saw no reptiles. One insect, however, was abundant, and that was the common or house fly. There they came, "not as single spies, but in battalions," as I think the Old Testament says somewhere. He is an extraordinary animal, is the house fly. Go where you will you find him, and so it must always have been. I have seen him enclosed in amber which must, I was told, have been half a million years old, looking exactly like his descendant of today, and I have little doubt that when the last man lies dying on the earth he will be buzzing round--if that event should happen to occur in summer--watching for an opportunity to settle on his nose.

At sunset we halted, waiting for the moon to rise. At ten she came up beautiful and serene as ever, and, with one halt about two o'clock in the morning, we trudged wearily on through the night, till at last the welcome sun put a period to our labors. We drank a little and flung ourselves down, thoroughly tired out, on the sand, and were soon all asleep. There was no need to set a watch, for we had nothing to fear from anybody or anything in that vast, untenanted plain. Our only enemies were heat, thirst, and flies, but far rather would I have faced any danger from man or beast than that awful trinity. This time we were not so lucky as to find a sheltering rock to guard us from the glare of the sun, with the result that about seven o'clock we woke up experiencing the exact sensations one would attribute to a beefsteak on a gridiron. We were literally being baked through and through. The burning sun seemed to be sucking our very blood out of us. We sat up. and gasped.

"Phew!" said I, grabbing at the halo of flies which buzzed cheerfully round my head. The heat did not affect them.

"My word," said Sir Henry.

"It _i_ is _i_ hot!" said Good.

It was hot, indeed, and there was not a bit of shelter to be had. Look where we would there was no rock or tree; nothing but an unending glare, rendered dazzling by the hot air which danced over the surface of the desert as it does over a red-hot stove.

"What is to be done?" asked Sir Henry; "we can't stand this for long." We looked at each other blankly.

"I have it," said Good; "we must dig a hole and get into it, and cover ourselves with the karoo bushes."

It did not seem a very promising suggestion, but at least it was better than nothing, so we set to work, and, with the trowel we had brought with us and our hands, succeeded in about an hour in delving out a patch of ground about ten feet long by twelve wide to the depth of two feet. Then we cut a quantity of low scrub with our hunting knives, and, creeping into the hole, pulled it over us all, with the exception of Ventvo"gel, on whom, being a Hottentot, the sun had no particular effect. This gave us some slight shelter from the burning rays of the sun, but the heat in that amateur grave can be better imagined than described. The Black Hole of Calcutta must have been a fool to it; indeed, to this moment; I do not know how we lived through the day. There we lay panting, and every now and again moistening our lips from our scanty supply of water. Had we followed our inclinations we should have finished off all we had in the first two hours, but we had to exercise the most rigid care, for if our water failed us we knew that we must quickly perish miserably.

But everything has an end, if only you live long enough to see it, and somehow that miserable day wore on towards evening. About three o'clock in the afternoon we determined that we could stand it no longer. It would be better to die walking than to be slowly killed by heat and thirst in that dreadful hole. So, taking each of. us a little drink from our fast diminishing supply of water now heated to about the same temperature as a man's blood, we staggered on.

We had now covered some fifty miles of desert. If my reader will refer to the rough copy and translation of old Da Silvestra's map he will see that the desert is marked as being forty leagues across, and the "pan bad water" is set down as being about in the middle of it. Now, forty leagues is one hundred and twenty miles; consequently, we ought at the most to be. within twelve or fifteen miles of the water, if any should really exist.

Through the. afternoon we crept slowly and painfully along, scarcely doing more than a mile and a half an hour. At sunset we again rested, waiting for the moon, and, after drinking a little, managed to get some sleep.

Before we lay down Umbopa pointed out to us a slight and indistinct hillock on the flat surface of the desert about eight miles away. At the distance it looked like an ant-hill, and as I was dropping off to sleep I fell to wondering what it could be.

With the moon we started on again, feeling dreadfully exhausted, and suffering tortures from thirst and prickly heat. Nobody who has not felt it can know what we went through. We no longer walked, we staggered, now and again falling from exhaustion, and being obliged to call a halt every hour or so. We had scarcely energy left in us to speak. Up to now Good had chatted and joked, for he was a merry fellow; but now he had not a joke left in him.

At last, about two o'clock, utterly worn out in body and mind, we came to the foot of this queer hill, or sand koppie, which did at first sight resemble a gigantic ant-heap about a hundred feet high, and covering at the base nearly a morgen (two acres) of ground.

Here we halted, and, driven by our desperate thirst, sucked down our last drops of water. We had but half a pint a head, and we could each have drank a gallon.

Then we lay down. Just as I was dropping off to sleep I heard Umbopa remark to himself in Zulu,

"If we cannot find water we shall all be dead before the moon rises morrow."

I shuddered, hot as it was. The near prospect of such an awful death is not pleasant, but even the thought of it could not keep me from sleeping.
