Proceeding farther along the edge of the lake we came to a metallic boat. This my guide picked up as easily as though it were of paper, for be it remembered that gravitation had slackened its hold here. Placing it upon the water, he stepped into it, and as directed I seated myself near the stern, my face to the bow, my back to the shore. The guide, directly in front of me, gently and very slowly moved a small lever that rested on a projection before him, and I gazed intently upon him as we sat together in silence. At last I became impatient, and asked him if we would not soon begin our journey. "We have been on our way since we have been seated," he answered. I gazed behind with incredulity: the shore had disappeared, and the diverging wake of the ripples showed that we were rapidly skimming the water. "This is marvelous," I said; "incomprehensible, for without sail or oar, wind or steam, we are fleeing over a lake that has no current." "True, but not marvelous. Motion of matter is a result of disturbance of energy connected therewith. Is it not scientifically demonstrated, at least in theory, that if the motion of the spirit that causes the magnetic needle to assume its familiar position were really arrested in the substance of the needle, either the metal would fuse and vaporize or (if the forces did not appear in some other form such as heat, electricity, magnetism, or other force) the needle would be hurled onward with great speed?" CHAPTER XXVI. MOTION FROM INHERENT ENERGY.--"LEAD ME DEEPER INTO THIS EXPANDING STUDY." "I partly comprehend that such would be the case," I said. "If a series of knife blades on pivot ends be set in a frame, and turned edgewise to a rapid current of water, the swiftly moving stream flows through this sieve of metallic edges about as easily as if there were no obstructions. Slowly turn the blades so as to present their oblique sides to the current, and an immediate pressure is apparent upon the frame that holds them; turn the blades so as to shut up the space, and they will be torn from their sockets, or the entire frame will be shattered into pieces." "I understand; go on."
