“And now,” said Sir Henry, “trek!”

So we started.

We had nothing to guide ourselves by except the distant mountains and old Jose da Silvestre’s chart, which, considering that it was drawn by a dying and half-distraught man on a fragment of linen three centuries ago, was not a very satisfactory sort of thing with work with.  Still, our sole hope of success depended upon it, such as it was.  If we failed in finding that pool of bad water which the old Dom marked as being situated in the middle of the desert, about sixty miles from our starting-point, and as far from the mountains, in all probability we must perish miserably of thirst.  But to my mind the chances of our finding it in that great sea of sand and karoo scrub seemed almost infinitesimal.  Even supposing that da Silvestra had marked the pool correctly, what was there to prevent its having been dried up by the sun generations ago, or trampled in by game, or filled with the drifting sand?

On we tramped silently as shades through the night and in the heavy sand.  The karoo bushes caught our feet and retarded us, and the sand worked into our veldtschoons and Good’s shooting-boots, so that every few miles we had to stop and empty them; but still the night kept 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 silent 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 startled us at the time, gave rise to a laugh.  Good was leading, as the holder of the compass, which, being a sailor, of course he understood thoroughly, 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 around us a most extraordinary hubbub, snorts, groans, and 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 run to, they cast themselves upon the ground and howled out that it was ghosts.  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 halloaing wildly.  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 upon a herd of sleeping quagga, on to the back of one of which Good actually had fallen, and the brute naturally enough got up and made off with him.  Calling 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 I found him sitting in the sand, his eye-glass still fixed firmly in his eye, rather shaken and very much frightened, but not in any way injured.
