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 misfiring 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 misfiring, 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 airtract. 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 taste of oil upon my lips, and there was a greasy scum upon the woodwork of the machine. Some infinitely fine organic matter appeared to be suspended in the atmosphere. There was no life there. It was inchoate and diffuse, extending for many square acres and then fringing off into the void. No, it was not life. But might it not be the remains of life? Above all, might it not be the food of life, of monstrous life, even as the humble grease of the ocean is the food for the mighty whale? The thought was in my mind when my eyes looked upwards and I saw the most wonderful vision that ever man has seen. Can I hope to convey it to you even as I saw it myself last Thursday?
'Conceive a jelly-fish such as sails in our summer seas, bell- shaped and of enormous size–far larger, I should judge, than the dome of St. Paul's. It was of a light pink colour veined with a delicate green, but the whole huge fabric so tenuous that it was but a fairy outline against the dark blue sky. It pulsated with a delicate and regular rhythm. From it there depended two long, drooping, green tentacles, which swayed slowly backwards and forwards. This gorgeous vision passed gently with noiseless dignity over my head, as light and fragile as a soap- bubble, and drifted upon its stately way.
'I had half-turned my monoplane, that I might look after this beautiful creature, when, in a moment, I found myself amidst a perfect fleet of them, of all sizes, but none so large as the first. Some were quite small, but the majority about as big as an average balloon, and with much the same curvature at the top. There was in them a delicacy of texture and colouring which reminded me of the finest Venetian glass. Pale shades of pink and green were the prevailing tints, but all had a lovely iridescence where the sun shimmered through their dainty forms. Some hundreds of them drifted past me, a wonderful fairy squadron of strange unknown argosies of the sky– creatures whose forms and substance were so attuned to these pure heights that one could not conceive anything so delicate within actual sight or sound of earth.
'But soon my attention was drawn to a new phenomenon–the serpents of the outer air. These were long, thin, fantastic coils of vapour-like material, which turned and twisted with great speed, flying round and round at such a pace that the eyes could hardly follow them. Some of these ghost-like creatures were twenty or thirty feet long, but it was difficult to tell their girth, for their outline was so hazy that it seemed to fade away into the air around them. These air-snakes were of a very light grey or smoke colour, with some darker lines within, which gave the impression of a definite organism. One of them whisked past my very face, and I was conscious of a cold, clammy contact, but their composition was so unsubstantial that I could not connect them with any thought of physical danger, any more than the beautiful bell-like creatures which had preceded them. There was no more solidity in their frames than in the floating spume from a broken wave.
'But a more terrible experience was in store for me. Floating downwards from a great height there came a purplish patch of vapour, small as I saw it first, but rapidly enlarging as it approached me, until it appeared to be hundreds of square feet in size. Though fashioned of some transparent, jelly-like substance, it was none the less of much more definite outline and solid consistence than anything which I had seen before. There were more traces, too, of a physical organization, especially two vast, shadowy, circular plates upon either side, which may have been eyes, and a perfectly solid white projection between them which was as curved and cruel as the beak of a vulture.
'The whole aspect of this monster was formidable and threatening, and it kept changing its colour from a very light mauve to a dark, angry purple so thick that it cast a shadow as it drifted between my monoplane and the sun. On the upper curve of its huge body there were three great projections which I can only describe as enormous bubbles, and I was convinced as I looked at them that they were charged with some extremely light gas which served to buoy up the misshapen and semi-solid mass in the rarefied air. The creature moved swiftly along, keeping pace easily with the monoplane, and for twenty miles or more it formed my horrible escort, hovering over me like a bird of prey which is waiting to pounce. Its method of progression–done so swiftly that it was not easy to follow–
