"But we are not floating," said Brice; "we are stationary. Is the lightness of your Fleotite counteracted by the weight of the men and machines?" Fraser shook his head. "Not entirely," he said. "But first look through this little window. Then I will explain." * * * * * Eagerly we pressed forward. Our danger was almost forgotten in our interest. This was amazing--stupendous! Together, shoulder to shoulder, we gazed through the aperture. We were suspended in space! Above us shone the blue-black Arabian night, and beneath us--far, far beneath--lay the sands of the desert looking rosy and warm in that same dull red glare of light that, to a fainter degree, gave us the effect of afterglow. But we were not floating; we were anchored as securely as a ship riding in a calm harbor. We turned back to Fraser, amazed, awed, bursting with questions. Madman he might be, but he had wrought a miracle. "I will explain," he said and his eyes gleamed with pride. "Of course you know of my tremendous discoveries connected with the power of light. At any rate, five years ago, the scientific world on earth thought they were tremendous. In reality that was nothing to my amazing strides in the past three years. There is nothing that cannot be done with light! Nothing!" For the first time Fraser's eyes became alive. They were illumined. His whole body seemed to radiate light and fire and genius. We listened, fascinated. "Take, for instance," he continued eagerly, "that ray with which I drew you and your plane to me. That ray is the pure power of magnetism. At full strength it will draw anything to it instantly. Fortunately the power can be regulated: I can switch a lever in my laboratory and draw things to me, via the ray, at any speed I wish--one hundred, two hundred, a thousand miles an hour." * * * * * "How far can you throw the ray?" asked Foulet, and I knew he was thinking of that glider that rose from the roof-tops of Constantinople. Fraser also knew he was thinking of that. "I did not draw the glider," he said quietly. "The airplane I sent did that. My airplanes carry batteries of this ray. In the beginning I found gliders to be more practical for my purposes than airplanes. For one thing they were silent. My only problem was that of getting them off the ground. Once they were in the air I could manage everything. It was this problem that inspired this discovery and perfection of the ray. But, you asked how far I can throw the ray? This main lamp, that I operate myself from here, is effective at two hundred miles. At one hundred miles it enjoys its full power." "And you can draw anything to you," asked Brice, "within the radius of the magnetic ray?"
