And it was not long that we had to wait. Only three days after my date of completion my notice arrived.
   It was an ordinary invitation card such as one uses for 'at homes,' and it ran thus:
   PROFESSOR G. E. CHALLENGER,
   F.R.S. MD., D.Sc., etc.
   (late President Zoological Institute and holder of so many honorary degrees and appointments that they overtax the capacity of this card) requests the attendance of
   MR. JONES (no lady)
   at 11.30 a.m. of Tuesday, June 21st, to witness a remarkable triumph of mind over matter
   at
   HENGIST DOWN, SUSSEX.
   Special train Victoria 10.5. Passengers pay their own fares. Lunch after the experiment or not – according to circumstances. Station, Storrington.
   R.S.V.P. (and at once with name in block letters), 14 (Bis), Enmore Gardens, S.W.
   I found that Malone had just received a similar missive over which he was chuckling.
   'It is mere swank sending it to us,' said he. 'We have to be there whatever happens, as the hangman said to the murderer. But I tell you this has set all London buzzing. The old man is where he likes to be, with a pin-point limelight right on his hairy old head.'
   And so at last the great day came. Personally I thought it well to go down the night before so as to be sure that everything was in order. Our borer was fixed in position, the weight was adjusted, the electric contacts could be easily switched on, and I was satisfied that my own part in this strange experiment would be carried out without a hitch. The electric controls were operated at a point some five hundred yards from the mouth of the shaft, to minimize any personal danger. When on the fateful morning, an ideal English summer day, I came to the surface with my mind assured, I climbed half-way up the slope of the Down in order to have a general view of the proceedings.
   All the world seemed to be coming to Hengist Down. As far as we could see the roads were dotted with people. Motor-cars came bumping and swaying down the lanes, and discharged their passengers at the gate of the compound. This was in most cases the end of their progress. A powerful band of janitors waited at the entrance, and no promises or bribes, but only the production of the coveted buff tickets, could get them any farther. They dispersed therefore and joined the vast crowd which was already assembling on the side of the hill and covering the ridge with a dense mass of spectators. The place was like Epsom Downs on the Derby Day. Inside the compound certain areas had been wired-off, and the various privileged people were conducted to the particular pen to which they had been allotted. There was one for peers, one for members of the House of Commons, and one for the heads of learned societies and the men of fame in the scientific world, including Le Pellier of the Sorbonne and Dr. Driesinger of the Berlin Academy. A special reserved enclosure with sandbags and a corrugated iron roof was set aside for three members of the Royal Family.
   At a quarter past eleven a succession of chars-a-bancs brought up specially-invited guests from the station and I went down into the compound to assist at the reception. Professor Challenger stood by the select enclosure, resplendent in frock-coat, white waistcoat, and burnished top-hat, his expression a blend of overpowering and almost offensive benevolence, mixed with most portentous self-importance. 'Clearly a typical victim of the Jehovah complex,' as one of his critics described him. He assisted in conducting and occasionally in propelling his guests into their proper places, and then, having gathered the elite of the company around him, he took his station upon the top of a convenient hillock and looked around him with the air of the chairman who expects some welcoming applause. As none was forthcoming, he plunged at once into his subject, his voice booming to the farthest extremities of the enclosure.
   'Gentlemen,' he roared, 'upon this occasion I have no need to include the ladies. If I have not invited them to be present with us this morning it is not, I can assure you, for want of appreciation, for I may say' – with elephantine humour and mock modesty – 'that the relations between us upon both sides have always been excellent, and indeed intimate. The real reason is that some small element of danger is involved in our experiment, though it is not sufficient to justify the discomposure which I see upon many of your faces. It will interest the members of the Press to know that I have reserved very special seats for them upon the spoil banks which immediately overlook the scene of the operation. They have shown an interest which is sometimes indistinguishable from impertinence in my affairs, so that on this occasion at least they cannot complain that I have been remiss in studying their convenience. If nothing happens, which is always possible, I have at least done my best for them. If, on the other hand, something does happen, they will be in an excellent position to experience and record it, should they ultimately feel equal to the task.
   'It is, as you will readily understand, impossible for a man of science to explain to what I may describe, without undue disrespect, as the common herd, the various reasons for his conclusions or his actions. I hear some unmannerly interruptions, and I will ask the gentleman with the horn spectacles to cease waving his umbrella. (A voice: "Your description of your guests, sir, is most offensive.") Possibly it is my phrase, "the common herd," which has ruffled the gentleman. Let us say, then, that my listeners are a most uncommon herd. We will not quibble over phrases. I was about to say, before I was interrupted by this unseemly remark, that the whole matter is very fully and lucidly discussed in my forthcoming volume upon the earth, which I may describe with all due modesty as one of the epoch-making books of the world's history. (General interruption and cries of "Get down to the facts!" "What are we here for?" "Is this a practical joke?") I was about to make the matter clear, and if I have any further interruption I shall be compelled to take means to preserve decency and order, the lack of which is so painfully obvious. The position is, then, that I have sunk a shaft through the crust of the earth and that I am about to try the effect of a vigorous stimulation of its sensory cortex, a delicate operation which will be carried out by my subordinates, Mr. Peerless Jones, a self-styled expert in Artesian borings, and Mr. Edward Malone, who represents myself upon this occasion. The exposed and sensitive substance will be pricked, and how it will react is a matter for conjecture. If you will now kindly take your seats these two gentlemen will descend into the pit and make the final adjustments. I will then press the electric button upon this table and the experiment will be complete.'
   An audience after one of Challenger's harangues usually felt as if, like the earth, its protective epidermis had been pierced and its nerves laid bare. This assembly was no exception, and there was a dull murmur of criticism and resentment as they returned to their places. Challenger sat alone on the top of the mound, a small table beside him, his black mane and beard vibrating with excitement, a most portentous figure. Neither Malone nor I could admire the scene, however, for we hurried off upon our extraordinary errand. Twenty minutes later we were at the bottom of the shaft, and had pulled the tarpaulin from the exposed surface.
   It was an amazing sight which lay before us. By some strange cosmic telepathy the old planet seemed to know that an unheard-of liberty was about to be attempted. The exposed surface was like a boiling pot. Great grey bubbles rose and burst with a crackling report. The air-spaces and vacuoles below the skin separated and coalesced in an agitated activity. The transverse ripples were stronger and faster in their rhythm than before. A dark purple fluid appeared to pulse in the tortuous anastomoses of channels which lay under the surface. The throb of life was in it all. A heavy smell made the air hardly fit for human lungs.
   My gaze was fixed upon this strange spectacle when Malone at my elbow gave a sudden gasp of alarm. 'My God, Jones!' he cried. 'Look there!'
   I gave one glance, and the next instant I released the electric connection and I sprang into the lift. 'Come on!' I cried. 'It may be a race for life!'
   What we had seen was indeed alarming. The whole lower shaft, it would seem, had shared in the increased activity which we had observed below, and the walls were throbbing and pulsing in sympathy. This movement had reacted upon the holes in which the beams rested, and it was clear that a very little further retraction – a matter of inches – the beams would fall. If they did so then the sharp end of my rod would, of course, penetrate the earth quite independently of the electric release. Before that happened it was vital that Malone and I should be out of the shaft. To be eight miles down in the earth with the chance any instant of some extraordinary convulsion taking place was a terrible prospect. We fled wildly for the surface.
   Shall either of us ever forget that nightmare journey? The lifts whizzed and buzzed and yet the minutes seemed to be hours. As we reached each stage we sprang out, jumped into the next lift, touched the release and flew onwards. Through the steel latticed roof we could see far away the little circle of light which marked the mouth of the shaft. Now it grew wider and wider, until it came full circle and our glad eyes rested upon the brickwork of the opening. Up we shot, and up – and then at last in a glad moment of joy and thankfulness we sprang out of our prison and had our feet upon the green sward once more. But it was touch and go. We had not gone thirty paces from the shaft when far down in the depths my iron dart shot into the nerve ganglion of old Mother Earth and the great moment had arrived.
   What was it happened? Neither Malone nor I was in a position to say, for both of us were swept off our feet as by a cyclone and swirled along the grass, revolving round and round like two curling stones upon an ice rink. At the same time our ears were assailed by the most horrible yell that ever yet was heard. Who is there of all the hundreds who have attempted it who has ever yet described adequately that terrible cry? It was a howl in which pain, anger, menace, and the outraged majesty of Nature all blended into one hideous shriek. For a full minute it lasted, a thousand sirens in one, paralysing all the great multitude with its fierce insistence, and floating away through the still summer air until it went echoing along the whole South Coast and even reached our French neighbours across the Channel. No sound in history has ever equalled the cry of the injured Earth.
   Dazed and deafened, Malone and I were aware of the shock and of the sound, but it is from the narrative of others that we learned the other details of that extraordinary scene.
   The first emergence from the bowels of the earth consisted of the lift cages. The other machinery being against the walls escaped the blast, but the solid floors of the cages took the full force of the upward current. When several separate pellets are placed in a blow-pipe they still shoot forth in their order and separately from each other. So the fourteen lift cages appeared one after the other in the air, each soaring after the other, and describing a glorious parabola which landed one of them in the sea near Worthing pier, and a second one in a field not far from Chichester. Spectators have averred that of all the strange sights that they had ever seen nothing could exceed that of the fourteen lift cages sailing serenely through the blue heavens.
   Then came the geyser. It was an enormous spout of vile treacly substance of the consistence of tar, which shot up into the air to a height which has been computed at two thousand feet. An inquisitive aeroplane, which had been hovering over the scene, was picked off as by an Archie and made a forced landing, man and machine buried in filth. This horrible stuff, which had a most penetrating and nauseous odour, may have represented the life blood of the planet, or it may be, as Professor Driesinger and the Berlin School maintain, that it is a protective secretion, analogous to that of the skunk, which Nature has provided in order to defend Mother Earth from intrusive Challengers. If that were so the prime offender, seated on his throne upon the hillock, escaped untarnished, while the unfortunate Press were so soaked and saturated, being in the direct line of fire, that none of them was capable of entering decent society for many weeks. This gush of putridity was blown southwards by the breeze, and descended upon the unhappy crowd who had waited so long and so patiently upon the crest of the Downs to see what would happen. There were no casualties. No home was left desolate, but many were made odoriferous, and still carry within their walls some souvenir of that great occasion.
   And then came the closing of the pit. As Nature slowly closes a wound from below upwards, so does the Earth with extreme rapidity mend any rent which is made in its vital substance. There was a prolonged high-pitched crash as the sides of the shaft came together, the sound, reverberating from the depths and then rising higher and higher until with a deafening bang the brick circle at the orifice flattened out and clashed together, while a tremor like a small earthquake shook down the spoil banks and piled a pyramid fifty feet high of debris and broken iron over the spot where the hole had been. Professor Challenger's experiment was not only finished, it was buried from human sight for ever. If it were not for the obelisk which has now been erected by the Royal Society it is doubtful if our descendants would ever know the exact site of that remarkable occurrence.
   And then came the grand finale. For a long period after these successive phenomena there was a hush and a tense stillness as folk reassembled their wits and tried to realize exactly what had occurred and how it had come about. And then suddenly the mighty achievement, the huge sweep of the conception, the genius and wonder of the execution, broke upon their minds. With one impulse they turned upon Challenger. From every part of the field there came the cries of admiration, and from his hillock he could look down upon the lake of upturned faces broken only by the rise and fall of the waving handkerchiefs. As I look back I see him best as I saw him then. He rose from his chair, his eyes half closed, a smile of conscious merit upon his face, his left hand upon his hip, his right buried in the breast of his frock-coat. Surely that picture will be fixed for ever, for I heard the cameras clicking round me like crickets in a field. The June sun shone golden upon him as he turned gravely bowing to each quarter of the compass. Challenger the super scientist, Challenger the arch-pioneer, Challenger the first man of all men whom Mother Earth had been compelled to recognize.
   Only a word by way of epilogue. It is of course well known that the effect of the experiment was a world-wide one. It is true that nowhere did the injured planet emit such a howl as at the actual point of penetration, but she showed that she was indeed one entity by her conduct elsewhere. Through every vent and every volcano she voiced her indignation. Hecla bellowed until the Icelanders feared a cataclysm. Vesuvius blew its head off. Etna spewed up a quantity of lava, and a suit of half-a-million lira damages has been decided against Challenger in the Italian Courts for the destruction of vineyards. Even in Mexico and in the belt of Central America there were signs of intense Plutonic indignation, and the howls of Stromboli filled the whole Eastern Mediterranean. It has been the common ambition of mankind to set the whole world talking. To set the whole world screaming was the privilege of Challenger alone.
