"Yes, I do. I mean that the next time the land slips our little tube will be twisted up like a piece of string, or crushed like an eggshell. That always was a rocky bit of land. I thought in going that far north, though, that we had missed the main line of activity; I mean the disturbances that had once wiped out a whole nation, if your scientists are correct." "Then you mean that it is only a matter of time?" "Yes, and I have been informed by one expert that the old volcanic activity is not dead either." "So that is what has stolen away your laugh?" "Well I am one of the engineers--and they won't suspend the service." "Fate has played an ugly trick on you, Dutch, and through your own dreams too. However, you have made me decide to go by the Tube." He took his pipe out of his mouth and stared at me. "Sooner or later the Tube will be through, and I have never been across. Nothing risked--a dull life. Mine has been altogether too dull. I am now most certainly going by the Tube." A bit of the old fire lit up his eyes. "Same old Bob," he grunted as I rose, and then he grasped my hand with a grin. "Good luck, my boy, on your journey, and may old Vulcan be out on a vacation when you pass his door." Thus we said good-by. I did not know then that I would never see him again--that he also took the train that night in order to make one last plea to the International Committee, and so laid down his life with the passengers for whom he had pleaded. It was with many conflicting thoughts, however, that I hurried to the great Terminus that fatal night, where after being ticketed, photographed and tabulated by an efficient army of clerks, I found myself in due time, being ushered to my car of the train. * * * * * For the benefit of those who have never ridden upon the famous "Flier," I could describe the cars no better than to say that coming upon them by night as I did, they looked like a gigantic, shiny worm, of strange shape, through whose tiny port-holes of heavy glass in the sides, glowed its luminous vitals. I was pompously shown to the front car, which very much resembled a tremendous cartridge--as did all of the other segments of this great glow-worm. Having dismissed the porter with a tip and the suspicion that my having the front car was the work of my friend, who was willing to give me my money's worth of thrill, and that the porter was aware of this, I stowed away my bags and started to get ready for bed. I had no sooner taken off my coat than the door was opened and an old fellow with a mass of silver hair peered in at me. "I beg your pardon, sir, but I understand you have engaged this car alone?" "Yes." "I can get no other accommodations tonight. You have an extra berth here and I must get to Paris tomorrow. I will pay you well--" I smiled. "Take it. I was beginning to feel lonesome, anyway."
