“Granted,” he said. “I sometimes say ‘dim’ myself, if I may quote Sir W. S. Gilbert. Go on.”

“When I went aboard the Rajah, neither the captain nor any of the officers offered opposition to my resuming command of the loading. The stuff was on the wharf, and in less than three days it was all aboard, well stowed away. During this time I had seen nothing to rouse my suspicion that anything underhand was to be attempted. I had informed the captain that you were now the charterer of the steamer, and he received the intelligence with apparent indifference, saying something to the effect that it mattered nothing to him who his owners were so long as his money was safe. The last material taken aboard was a large quantity of canvas for making tents, and lucky for me it was that I placed this at the foot of the ladder up from the hold. The workers had all gone on deck, and I was taking a final look around, wondering whether anything had been forgotten. I then mounted the ladder, and was amazed to see old Schwartzbrod standing there, talking to a tall, dark man who was, I afterwards learned, the leader of the expedition. This man, without a word, planted his foot against my breast, and heaved me backward down into the hold. Immediately afterwards I was battened down, and in darkness. By the running about on the deck above me, I realized that the steamer was getting ready to cast off, and within an hour I heard the engines and screw at work.

“It was night, and we were thrashing seaward through the Channel when the covering of the hatchway was lifted, and the man who had imprisoned me came down the ladder alone, with a lantern in his hand, which struck me as rather brave in the circumstances, but then he was armed, and I was not, so after all I had little chance against him. He placed the lantern on the bales of canvas upon which I had fallen, and began, with seeming courtesy, by begging pardon for what he had done. Throughout he spoke very quietly, and impressed me as a determined and capable person. He said that if I gave him my word that I should speak to no one aboard, or attempt to hail any passing craft, should such come near us, he would allow me on deck, and would send me ashore when the pilot left the ship.

“‘And if I refuse to give my word?’ I asked. “’ In that case,’ he replied, ‘I shall supply you with food and water, and will carry you to the end of our voyage.’

“‘And where is that?’ I asked.

“‘I don’t know,’ he said. ‘I have nothing to do with the navigation of the ship. I believe we are making for some port in South America, but I couldn’t say for certain.’

“I realized that I could do nothing while in the hold, and although I knew perfectly well they were making for the West African coast, and not for South America, I would be equally helpless once I reached there. Besides, it was of vital importance that I should telegraph to you and my father. In fact, I was amazed that, having taken the risk of placing me in confinement as they had done, they should allow me to get on shore so soon, but I suppose the crafty old Schwartzbrod knew that if I remained missing long, there would be an outcry in the newspapers, so he reckoned it was safer to risk my being put ashore, as he estimated we could not possibly fit out another steamer and start in pursuit under a week at the very least, and with that start they could have the channel of the river blocked, a fort or two erected, and so bid us defiance when we did arrive.”

“But if they blocked the river,” interrupted his lordship, “they would shut themselves in, as well as shut us out.”

“Not necessarily,” continued the engineer. “I have reason to believe that before I reached Southampton, a number of floating mines were stowed away in the front part of the ship. These mines could be planted in the mouth of the river, and a chart kept, which, in the possession of the captain, would enable him to thread the channel in safety, while a navigator without this protection and guide would run a thousand chances of finding his ship blown up.”

“Why,” said his lordship with admiration, “our seven syndicaters are brave as the buccaneers of ancient times. They are certainly running considerable risk of penal servitude for life?”
