Part 1 (2/2)

My uncle had predicted correctly, for by the time I again came home on my vacation, the newly elected Pacifist Council had reduced the aerial activities to mere watchful patroling over the land of the enemy. Then came the report of an attempt to launch an airplane from the roof of Berlin. The people, in dire panic lest Ray generators were being carried out by German aircraft, had clamoured for the recall of the Pacifist Council, and the bombardment of Berlin was resumed.

During the lull of the bombing activities my uncle, who stood high with the Pacifist Administration, had obtained permission to fly over Europe, and I, most fortunate of boys, accompanied him. The plane in which we travelled bore the emblem of the World Patrol. On a cloudless day we sailed over the pock-marked desert that had once been Germany and came within field-gla.s.s range of Berlin itself. On the wasted, bomb-torn land lay the great grey disc--the city of mystery. Three hundred metres high they said it stood, but so vast was its extent that it seemed as flat and thin as a pancake on a griddle.

”More people live in that ma.s.s of concrete,” said my uncle, ”than in the whole of America west of the Rocky Mountains.” His statement, I have since learned, fell short of half the truth, but then it seemed appalling. I fancied the city a giant anthill, and searched with my gla.s.s as if I expected to see the ants swarming out. But no sign of life was visible upon the monotonous surface of the sand-blanketed roof, and high above the range of naked vision hung the hawk-like watchers of the World Patrol.

The lure of unravelled secrets, the ambition for discovery and exploration stirred my boyish veins. Yes, I would know more of the strange race, the unknown life that surged beneath that grey blanket of mystery. But how? For over a century millions of men had felt that same longing to know. Aviators, landing by accident or intent within the lines, had either returned with nothing to report, or they had not returned. Daring journalists, with baskets of carrier pigeons, had on foggy nights dropped by parachute to the roof of the city; but neither they nor the birds had brought back a single word of what lay beneath the armed and armoured roof.

My own resolution was but a boy's dream and I returned to Chicago to take up my chemical studies.

CHAPTER II

I EXPLORE THE POTASH MINES OF STa.s.sFURT AND FIND A DIARY IN A DEAD MAN'S POCKET

~1~

When I was twenty-four years old, my uncle was killed in a laboratory explosion. He had been a scientist of renown and a chemical inventor who had devoted his life to the unravelling of the secrets of the synthetic foods of Germany. For some years I had been his trusted a.s.sistant. In our Chicago laboratory were carefully preserved food samples that had been taken from the captured submarines in years gone by; and what to me was even more fascinating, a collection of German books of like origin, which I had read with avidity. With the exception of those relating to submarine navigation, I found them stupidly childish and decided that they had been prepared to hide the truth and not reveal it.

My uncle had bequeathed me both his work and his fortune, but despairing of my ability worthily to continue his own brilliant researches on synthetic food, I turned my attention to the potash problem, in which I had long been interested. My reading of early chemical works had given me a particular interest in the reclamation of the abandoned potash mines of Sta.s.sfurt. These mines, as any student of chemical history will know, were one of the richest properties of the old German state in the days before the endless war began and Germany became isolated from the rest of the world. The mines were captured by the World in the year 2020, and were profitably operated for a couple of decades. Meanwhile the German lines were forced many miles to the rear before the impregnable barrier of the Ray had halted the progress of the World Armies.

A few years after the coming of the Ray defences, occurred what history records as ”The Tragedy of the Mines.” Six thousand workmen went down into the potash mines of Sta.s.sfurt one morning and never came up again.

The miners' families in the neighbouring villages died like weevils in fumigated grain. The region became a valley of pestilence and death, and all life withered for miles around. Numerous governmental projects were launched for the recovery of the potash mines but all failed, and for one hundred and eleven years no man had penetrated those accursed shafts.

Knowing these facts, I wasted no time in soliciting government aid for my project, but was content to secure a permit to attempt the recovery with private funds, with which my uncle's fortune supplied me in abundance.

In April, 2151, I set up my laboratory on the edge of the area of death.

I had never accepted the orthodox view as to the composition of the gas that issued from the Sta.s.sfurt mines. In a few months I was gratified to find my doubts confirmed. A short time after this I made a more unexpected and astonis.h.i.+ng discovery. I found that this complex and hitherto misunderstood gas could, under the influence of certain high-frequency electrical discharges, be made to combine with explosive violence with the nitrogen of the atmosphere, leaving only a harmless residue. We wired the surrounding region for the electrical discharge and, with a vast explosion of weird purple flame, cleared the whole area of the century-old curse. Our laboratory was destroyed by the explosion.

It was rebuilt nearer the mine shafts from which the gas still slowly issued. Again we set up our electrical machinery and dropped our cables into the shafts, this time clearing the air of the mines.

A hasty exploration revealed the fact that but a single shaft had remained intact. A third time we prepared our electrical machinery. We let down a cable and succeeded in getting but a faint reaction at the bottom of the shaft. After several repeated clearings we risked descent.

Upon arrival at the bottom we were surprised to find it free from water, save for a trickling stream. The second thing we discovered was a pile of huddled skeletons of the workmen who had perished over a century previous. But our third and most important discovery was a boring from which the poisonous gas was slowly issuing. It took but a few hours to provide an apparatus to fire this gas as fast as it issued, and the potash mines of Sta.s.sfurt were regained for the world.

My a.s.sociates were for beginning mining operations at once, but I had been granted a twenty years' franchise on the output of these mines, and I was in no such haste. The boring from which this poisonous vapour issued was clearly man-made; moreover I alone knew the formula of that gas and had convinced myself once for all as to its man-made origin. I sent for microphones and with their aid speedily detected the sound of machinery in other workings beneath.

It is easy now to see that I erred in risking my own life as I did without the precaution of confiding the secret of my discovery to others. But those were days of feverish excitement. Impulsively I decided to make the first attack on the Germans as a private enterprise and then call for military aid. I had my own equipment of poisonous bombs and my sapping and mining experts determined that the German workings were but eighty metres beneath us. Hastily, among the crumbling skeletons, we set up our electrical boring machinery and began sinking a one-metre shaft towards the nearest sound.

After twenty hours of boring, the drill head suddenly came off and rattled down into a cavern. We saw a light and heard guttural shouting below and the cracking of a gun as a few bullets spattered against the roof of our chamber. We heaved down our gas bombs and covered over our shaft. Within a few hours the light below went out and our microphones failed to detect any sound from the rocks beneath us. It was then perhaps that I should have called for military aid, but the uncanny silence of the lower workings proved too much for my eager curiosity. We waited two days and still there was no evidence of life below. I knew there had been ample time for the gas from our bombs to have been dissipated, as it was decomposed by contact with moisture. A light was lowered, but this brought forth no response.

I now called for a volunteer to descend the shaft. None was forthcoming from among my men, and against their protest I insisted on being lowered into the shaft. When I was a few metres from the bottom the cable parted and I fell and lay stunned on the floor below.
