Furious with rage, we turned and retraced our way towards the road. We had come nearly thirty miles westward instead of turning, as we ought to have done, to the east, and had wasted a day and a half—it was intolerable! If we had met the Strongs at this time there would have been a battle; we were blood-hot, and should not have spared them. They had tricked us, and had, in all probability, unearthed the treasure by this time, and departed with it. I could not trust myself to speak as we rode swiftly back, in grim silence, upon our own tracks. Jack said nothing either.
That night, as we lay by our fire, it suddenly occurred to me to look at my revolver. It, after all, had been in my small black bag as well as the map. Probably they had tampered with it; for, otherwise, why should my weapon have missed fire and Jack's not? They had soused my cartridges—that much was pretty certain; but perhaps they had done the revolver some injury besides.
I examined it carefully. The lock worked all right; the drum revolved perfectly. I looked down the barrel; looked straight down it at the firelight, and saw nothing.
"Well?" said Jack.
I handed him the revolver. Jack looked down the barrel as I had; then he took a thin stick and poked at it.
"The demons!" he said; "they've choked it with lead or something. Curse them! it would have burst in your hand if you had fired it! We'll pay them out for this, Peter, if we have to chase them half round the world for it!"
Thirty miles back to the waggon road, twenty miles farther northwards, and then at last we were at the spot where, according to the original map, we should have turned off at the village called Ngami. Our bogus map gave no name to the village, which showed, as Jack said, the fiendish cunning of the Strongs; for if they had called it Ngami, we should have gone on until we had reached a village of that name, and from it we should have plainly seen, as we now saw, the conical hill on our right. As it was, we had gone sixty miles out of our way, and might have gone six hundred, or, indeed, never have struck the right road at all, but for my happy idea on board ship to take a copy of the map in case of accidents.
It was dusk when we arrived, riding with exceeding caution, within a mile or so of the conical hill. Here we dismounted by Jack's orders; for he, by the most natural process in the world—namely, the simple slipping into his proper place, as nature intends that people like Jack should do—had assumed the leadership of our party of two. It was quite right and proper that he should lead, for Jack had twice the resource and the readiness that I had been furnished withal; his wits were quicker workers than mine, and his judgment far more acute and correct. Jack decreed, then, that we should dismount and wait, and listen. If they had not yet found the treasure, he said, they would, of course, still be upon the ground; and if there, they would certainly light a fire when darkness fell.
"Then will come our chance!" added Jack.
"Of doing what?" I asked. "You don't think of shooting them asleep, Jack, surely!"
