Danger! - Sir Arthur Conan Doyle (urban books to read .TXT) 📗

In my anxiety to get clear, I cocked her nose up until the automatic alarm-bell rang, and I actually began to slide backwards. My sopped and dripping wings had made me heavier than I thought, but presently I was in lighter cloud, and soon had cleared the first layer. There was a second--opal-coloured and fleecy--at a great height above my head, a white unbroken ceiling above, and a dark unbroken floor below, with the monoplane labouring upwards upon a vast spiral between them. It is deadly lonely in these cloud-spaces. Once a great flight of some small water-birds went past me, flying very fast to the westwards. The quick whirr of their wings and their musical cry were cheery to my ear. I fancy that they were teal, but I am a wretched zoologist. Now that we humans have become birds we must really learn to know our brethren by sight.

"The wind down beneath me whirled and swayed the broad cloud-plain. Once a great eddy formed in it, a whirlpool of vapour, and through it, as down a funnel, I caught sight of the distant world. A large white biplane was passing at a vast depth beneath me. I fancy it was the morning mail service betwixt Bristol and London. Then the drift swirled inwards again and the great solitude was unbroken.

"Just after ten I touched the lower edge of the upper cloud-stratum. It consisted of fine diaphanous vapour drifting swiftly from the westward. The wind had been steadily rising all this time and it was now blowing a sharp breeze--twenty-eight an hour by my gauge. Already it was very cold, though my altimeter only marked nine thousand. The engines were working beautifully, and we went droning steadily upwards. The cloud- bank was thicker than I had expected, but at last it thinned out into a golden mist before me, and then in an instant I had shot out from it, and there was an unclouded sky and a brilliant sun above my head--all blue and gold above, all shining silver below, one vast glimmering plain as far as my eyes could reach. It was a quarter past ten o'clock, and the barograph needle pointed to twelve thousand eight hundred. Up I went and up, my ears concentrated upon the deep purring of my motor, my eyes busy always with the watch, the revolution indicator, the petrol lever, and the oil pump. No wonder aviators are said to be a fearless race. With so many things to think of there is no time to trouble about oneself. About this time I noted how unreliable is the compass when above a certain height from earth. At fifteen thousand feet mine was pointing east and a point south. The sun and the wind gave me my true bearings.

"I had hoped to reach an eternal stillness in these high altitudes, but with every thousand feet of ascent the gale grew stronger. My machine groaned and trembled in every joint and rivet as she faced it, and swept away like a sheet of paper when I banked her on the turn, skimming down wind at a greater pace, perhaps, than ever mortal man has moved. Yet I had always to turn again and tack up in the wind's eye, for it was not merely a height record that I was after. By all my calculations it was above little Wiltshire that my air-jungle lay, and all my labour might be lost if I struck the outer layers at some farther point.

"When I reached the nineteen-thousand-foot level, which was about midday, the wind was so severe that I looked with some anxiety to the stays of my wings, expecting momentarily to see them snap or slacken. I even cast loose the parachute behind me, and fastened its hook into the ring of my leathern belt, so as to be ready for the worst. Now was the time when a bit of scamped work by the mechanic is paid for by the life of the aeronaut. But she held together bravely. Every cord and strut was humming and vibrating like so many harp-strings, but it was glorious to see how, for all the beating and the buffeting, she was still the conqueror of Nature and the mistress of the sky. There is surely something divine in man himself that he should rise so superior to the limitations which Creation seemed to impose--rise, too, by such unselfish, heroic devotion as this air-conquest has shown. Talk of human degeneration! When has such a story as this been written in the annals of our race?

"These were the thoughts in my head as I climbed that monstrous inclined plane with the wind sometimes beating in my face and sometimes whistling behind my ears, while the cloud-land beneath me fell away to such a distance that the folds and hummocks of silver had all smoothed out into one flat, shining plain. But suddenly I had a horrible and unprecedented experience. I have known before what it is to be in what our neighbours have called a _tourbillon_, but never on such a scale as this. That huge, sweeping river of wind of which I have spoken had, as it appears, whirlpools within it which were as monstrous as itself. Without a moment's warning I was dragged suddenly into the heart of one. I spun round for a minute or two with such velocity that I almost lost my senses, and then fell suddenly, left wing foremost, down the vacuum funnel in the centre. I dropped like a stone, and lost nearly a thousand feet. It was only my belt that kept me in my seat, and the shock and breathlessness left me hanging half-insensible over the side of the fuselage. But I am always capable of a supreme effort--it is my one great merit as an aviator. I was conscious that the descent was slower. The whirlpool was a cone rather than a funnel, and I had come to the apex. With a terrific wrench, throwing my weight all to one side, I levelled my planes and brought her head away from the wind. In an instant I had shot out of the eddies and was skimming down the sky. Then, shaken but victorious, I turned her nose up and began once more my steady grind on the upward spiral. I took a large sweep to avoid the danger- spot of the whirlpool, and soon I was safely above it. Just after one o'clock I was twenty-one thousand feet above the sea-level. To my great joy I had topped the gale, and with every hundred feet of ascent the air grew stiller. On the other hand, it was very cold, and I was conscious of that peculiar nausea which goes with rarefaction of the air. For the first time I unscrewed the mouth of my oxygen bag and took an occasional whiff of the glorious gas. I could feel it running like a cordial through my veins, and I was exhilarated almost to the point of drunkenness. I shouted and sang as I soared upwards into the cold, still outer world.

"It is very clear to me that the insensibility which came upon Glaisher, and in a lesser degree upon Coxwell, when, in 1862, they ascended in a balloon to the height of thirty thousand feet, was due to the extreme speed with which a perpendicular ascent is made. Doing it at an easy gradient and accustoming oneself to the lessened barometric pressure by slow degrees, there are no such dreadful symptoms. At the same great height I found that even without my oxygen inhaler I could breathe without undue distress. It was bitterly cold, however, and my thermometer was at zero Fahrenheit. At one-thirty I was nearly seven miles above the surface of the earth, and still ascending steadily. I found, however, that the rarefied air was giving markedly less support to my planes, and that my angle of ascent had to be considerably lowered in consequence. It was already clear that even with my light weight and strong engine-power there was a point in front of me where I should be held. To make matters worse, one of my sparking-plugs was in trouble again and there was intermittent missfiring in the engine. My heart was heavy with the fear of failure.

"It was about that time that I had a most extraordinary experience. Something whizzed past me in a trail of smoke and exploded with a loud, hissing sound, sending forth a cloud of steam. For the instant I could not imagine what had happened. Then I remembered that the earth is for ever being bombarded by meteor stones, and would be hardly inhabitable were they not in nearly every case turned to vapour in the outer layers of the atmosphere. Here is a new danger for the high-altitude man, for two others passed me when I was nearing the forty-thousand-foot mark. I cannot doubt that at the edge of the earth's envelope the risk would be a very real one.

"My barograph needle marked forty-one thousand three hundred when I became aware that I could go no farther. Physically, the strain was not as yet greater than I could bear, but my machine had reached its limit. The attenuated air gave no firm support to the wings, and the least tilt developed into side-slip, while she seemed sluggish on her controls. Possibly, had the engine been at its best, another thousand feet might have been within our capacity, but it was still missfiring, and two out of the ten cylinders appeared to be out of action. If I had not already reached the zone for which I was searching then I should never see it upon this journey. But was it not possible that I had attained it? Soaring in circles like a monstrous hawk upon the forty-thousand-foot level I let the monoplane guide herself, and with my Mannheim glass I made a careful observation of my surroundings. The heavens were perfectly clear; there was no indication of those dangers which I had imagined.

"I have said that I was soaring in circles. It struck me suddenly that I would do well to take a wider sweep and open up a new air-tract. If the hunter entered an earth-jungle he would drive through it if he wished to find his game. My reasoning had led me to believe that the air-jungle which I had imagined lay somewhere over Wiltshire. This should be to the south and west of me. I took my bearings from the sun, for the compass was hopeless and no trace of earth was to be seen--nothing but the distant silver cloud-plain. However, I got my direction as best I might and kept her head straight to the mark. I reckoned that my petrol supply would not last for more than another hour or so, but I could afford to use it to the last drop, since a single magnificent vol-plane could at any time take me to the earth.

"Suddenly I was aware of something new. The air in front of me had lost its crystal clearness. It was full of long, ragged wisps of something which I can only compare to very fine cigarette-smoke. It hung about in wreaths and coils, turning and twisting slowly in the sunlight. As the monoplane shot through it, I was aware of a faint
