perfected. You've been invaluable, dear boy, invaluable!" His voice faded. "Professor!" I screamed futilely, but by then we were too far apart to make ourselves heard and, even as I wasted my breath, a gust of wind caught me and sent me soaring into the air, spinning like a top. But, just before I entered a cloud, I saw the Professor standing far below, his feet planted wide apart, his head thrown back while he watched my progress. I fancied that, as I disappeared into the mist, he waved a solemn good-by and drank my health. You can't imagine the torture I went through as I sailed through the air. During those first few moments, I had felt light, carefree, buoyant. But, in these higher altitudes, I was buffeted by strong winds, pelted by rain in enormous quantities and subjected to sudden drops that had me gasping. How I managed to survive, I can't understand. Surely, I would have died if I had floated completely out of the atmosphere but, luckily, the belt's power to lift me leveled off at about 10,000 feet. For days, I drifted at that altitude, blown willy-nilly by the contrary winds, starved and bitterly cold. Several times, I tried to steer myself—but to no avail. I was powerless to control my flight. My sense of direction left me and I had no idea where I was. Sometimes, I would look down through a rift in the clouds and see farmland, or perhaps cities. Once I glimpsed the sea—and shut my eyes. It was not until the sixth day of my flight that I noticed a change. I was sinking. Slowly but steadily, I was losing altitude. I was at a loss to explain this phenomenon at first, but then I remembered that the Professor had said the belt was powered by batteries. Obviously, the batteries were weakening. A few hours later, I landed gently, only a few blocks from where I had started my unwilling flight. During those six frightful days, I must have been blown around in circles. Weak, starved, shaken, sick, I was taken to a hospital, from which I have just been released. Needless to say, I immediately tried to locate Professor Burdinghaugh, but have been unable to find a trace of him. You might say he has disappeared into thin air. You must be wondering, of course, what this singular adventure has to do with my not writing you earlier. However, I feel certain you understand now that writing was impossible under the circumstances. All the ink in my fountain pen leaked out when I reached the altitude of 10,000 feet—I have the kind of
