A moment later I heard a noise like ten dog-fights rolled into one, and rushing out I found my friend rolling on the ground with his arms round the workman who was helping to stack my artesian tubing. He was endeavouring to tear something from him to which the other was most desperately clinging. But Malone was too strong for him, tore the object out of his grasp, and danced upon it until it was shattered to pieces. Only then did I recognize that it was a photographic camera. My grimy-faced artisan rose ruefully from the floor.

'Confound you, Ted Malone!' said he. 'That was a new ten-guinea machine.'

'Can't help it, Roy. I saw you take the snap, and there was only one thing to do.'

'How the devil did you get mixed up with my outfit?' I asked, with righteous indignation.

The rascal winked and grinned. 'There are always and means,' said he. 'But don't blame your foreman. He thought it was just a rag. I swapped clothes with his assistant, and in I came.'

'And out you go,' said Malone. 'No use arguing, Roy. If Challenger were here he would set the dogs on you. I've been in a hole myself so I won't be hard, but I am watch-dog here, and I can bite as well as bark. Come on! Out you march!'

So our enterprising visitor was marched by two grinning workmen out of the compound. So now the public will at last understand the genesis of that wonderful four-column article headed 'Mad Dream of a Scientist' with the subtitle. 'A Bee-line to Australia,' which appeared in The Adviser some days later and brought Challenger to the verge of apoplexy, and the editor of The Adviser to the most disagreeable and dangerous interview of his lifetime. The article was a highly coloured and exaggerated account of the adventure of Roy Perkins, 'our experienced war correspondent' and it contained such purple passages as 'this hirsute bully of Enmore Gardens,' 'a compound guarded by barbed wire, plug-uglies, and bloodhounds,' and finally, 'I was dragged from the edge of the Anglo-Australian tunnel by two ruffians, the more savage being a jack-of-all trades whom I had previously known by sight as a hanger-on of the journalistic profession, while the other, a sinister figure in a strange tropical garb, was posing as an Artesian engineer, though his appearance was more reminiscent of Whitechapel.' Having ticked us off in this way, the rascal had an elaborate description of rails at the pit mouth, and of a zigzag excavation by which funicular trains were to burrow into the earth. The only practical inconvenience arising from the article was that it notably increased that line of loafers who sat upon the South Downs waiting for something to happen. The day came when it did happen and when they wished themselves elsewhere.

My foreman with his faked assistant had littered the place with all my apparatus, my bellbox, my crowsfoot, the V-drills, the rods, and the weight, but Malone insisted that we disregard all that and descend ourselves to the lowest level. To this end we entered the cage, which was of latticed steel, and in the company of the chief engineer we shot down into the bowels of the earth. There were a series of automatic lifts, each with its own operating station hollowed out in the side of the excavation. They operated with great speed, and the experience was more like a vertical railway journey than the deliberate fall which we associate with the British lift.

Since the cage was latticed and brightly illuminated, we had a clear view of the strata which we passed. I was conscious of each of them as we flashed past. There were the sallow lower chalk, the coffee-coloured Hastings beds, the lighter Ashburnham beds, the dark carboniferous clays, and then, gleaming in the electric light, band after band of jet-black, sparkling coal alternating with the rings of clay. Here and there brickwork had been inserted, but as a rule the shaft was self-supported, and one could but marvel at the immense labour and mechanical skill which it represented. Beneath the coal-beds I was conscious of jumbled strata of a concrete-like appearance, and then we shot down into the primitive granite, where the quartz crystals gleamed and twinkled as if the dark walls were sown with the dust of diamonds. Down we went and ever down – lower now than ever mortals had ever before penetrated. The archaic rocks varied wonderfully in colour, and I can never forget one broad belt of rose-coloured felspar, which shone with an unearthly beauty before our powerful lamps. Stage after stage, and lift after lift, the air getting ever closer and hotter until even the light tussore garments were intolerable and the sweat was pouring down into those rubber-soled slippers.
