Russell paused and helped himself to a fresh cigarette.

"Mind you, I am not taking credit to myself for any philanthropy," he went on. "I admit those people were very good to me, but I wanted to get back to civilization nevertheless. And I am afraid I was thinking more about those jewels than anything else. If I could succeed in reaching the coast with them, why, then, my fortune was made. All these thoughts passed swiftly through my mind as I crouched behind the friendly shelter, watching Flower and his companions. There were two Europeans besides himself, and some half-a-dozen natives who stood at a distance waiting for orders. It puzzled me to know what they were doing up there, and it was some little time before I could make out. But gradually the thing began to appear plainer, for one of the Europeans came along with something in his hand which I made out to be an electric battery. This man silently paced along the whole length of the dam, then he proceeded to make pencil notes in a pocket-book. Flower seemed to be watching him carefully, as if waiting for a verdict.

"'No great difficulty,' said the man with the pocket-book by and by. 'On the whole the thing appears feasible. It only means removing a stone or two and applying a big charge of dynamite and the thing is done. I don't think we need take the trouble to keep our men here. The less people we have about us the better. We can easily find some excuse for sending them to the coast. It is by far the most expeditious plan, to say nothing of its absolute safety.'

"'And those places down there?' Flower asked.

"The man with the battery shrugged his shoulders.

"'What does it matter?' he asked. 'It will only make the game exciting afterwards—the finest game of hide-and-seek you ever had in your life. You leave it to me and I'll fix it all right. And the sooner it comes off the better.'"

Russell made another pause.

"I daresay you will think me stupid," he said, "but for the moment I could not make out what those fellows were doing. I knew there was mischief on foot. I knew that Samuel Flower would never come all that way for nothing. But, for the life of me, I couldn't see what they were driving at. I stayed there thinking the matter over long after Flower and his companions had gone, but the more I pondered the more muddled I grew. Still, I decided to go down presently and see how the chief was progressing. It only wanted a glance in the moonlight to see what had happened. The poor fellow was dead. He had told me the sober truth. He had fallen by a poisoned arrow shot by one of those miscreants who had guided Flower and his companions to that out-of-the-way corner of the world.

"But there was nothing for it but to wait for the morning. I went back to my own quarters sorrowfully enough, feeling that I had lost what little power I possessed, for since the chief was dead my reputation for surgery would vanish to nothing. I might alarm the natives in the morning and try to show them what was in store for them if they had not much faith in my diplomacy. I lay on my bed full of fears and none the less alarmed because I did not know in which quarter to look for the danger. I suppose I must have dozed off into a sort of sleep, when I was alarmed by a tremendous crash and boom overhead as if a mighty thunderstorm were in progress, and a moment later I heard the torrents of rain roaring down the flinty streets. Even then I did not connect this with the peril to come, though it was impossible to sleep for the noise of the rushing waters, and I sat up in bed. Presently I could see the yellow flood creeping into my room and almost before I knew where it was it was knee-deep on the floor.

"And then it flashed across me what had happened. The truth came too late. I saw once more in my mind's eye the man jotting down his calculations in a pocket-book. It came back to me with vivid force what he had said about the dynamite, and I knew. They had removed some of the heavy coping-stones from the top of the dam, then with the aid of their battery they had fired a mine of dynamite, and in the twinkling of an eye the dam was no more. The huge wall had been removed as if by a gigantic knife, and the great lake overhead was rushing on to the destruction of the city. In a few minutes every man, woman and child would perish, and the gigantic buildings be torn apart like so many packs of cards.
