Spawn of the Comet Part 5

Before many days, however, Overton, with the rest of the world, was turning anxiously to Professor Wentworth, watching his every move, awaiting his every word. For before many days terrible reports started coming in, not only from the Arizona desert but from the a.s.sembly grounds of the Fire Ants everywhere.

Those deadly termites were on the move! They were spreading from their central citadels in ominous, expanding circles--circles that engulfed villages, towns and cities in a swift, relentless ring of annihilation that was fairly stupefying.

In North America, the cities of Phoenix, Tucson and Prescott, with all that lay between, were already gone, their frantic populaces fleeing to the four points of the compa.s.s before that fateful orange tide. In South America, Rosario and Cordoba were within the flaming ring and Buenos Aires was threatened. In Europe, Moscow and its vast tributary plain had fallen before the invaders. In Asia, a veritable inland empire was theirs, reaching from Urga to the Khingan Mountains. In Africa, Southern Algeria and French Sudan, with their innumerable small villages and oases, were overrun. In Australia, Coolgardie had succ.u.mbed and Perth was in a panic.

But fearful though the destruction was on the continents, it was the islands of the world that suffered most. First the smallest, those picturesque green gems of the South Seas, crisped and perished. Then came reports of the doom of the Hawaiian group, the Philippines, the East and West Indies, New Zealand, Tasmania and a score of others, their populations peris.h.i.+ng by the thousands, as s.h.i.+pping proved unavailable to transport them to safety.

By far the most tragic fate, however, was that suffered by the British Isles. What happened there stunned the world, and brought realization to humanity that unless some miracle intervened, it was but a mirror of the doom that awaited all. For England, Ireland and Scotland were habitable no more. London, Dublin, Glasgow--all their proud cities, all their peaceful hamlets, centuries old, were flaming ruins.

Out of a population, of some sixty millions, it was estimated that at least eight millions must have perished. The rest, by prodigious feats of transportation, managed to reach the mainland, where they spread as refugees throughout an apprehensive, demoralized Europe.

As for the armies and navies of the world, they were powerless before this fiendish invader. Hammered with high explosives, drenched with chemicals, sprayed with machine-gun ballets, the fiery termites surged on unchecked, in ever-widening circles of death.

Lead and steel pa.s.sed through them harmlessly. Gas wafted off them like air. Despite the frantic efforts of scientists and military men, nothing could be devised to stem that all-devouring orange tide.

It was quite obvious by now, even to the most conservative minds, that the end of human life on earth was not far off. It could only be a few more weeks before the last stronghold fell. Daily, hourly, those deadly Fire Ants were everywhere expanding their fields of operations.

Presently all humanity would be driven to the seacoasts, there to perish by fire or water, as they chose.

There were some optimists, of course, who believed that the miracle would happen--that Professor Wentworth or some other scientist would devise some means of repelling the invader before it was too late.

Young Jim Carter of _The York Press_ was not among them, however, though he would have gambled it would be Professor Wentworth if anyone. For what hope was there that any mere man could figure out a weapon that would be effective against such a deadly, such a superhuman foe?

Very little, it seemed, and he grew less and less sanguine, as he continued his frenzied, sleepless work of reporting the unending catastrophes for his paper.

He often thought bitterly of that ten thousand dollars. A lot of good that would do him now!

As for Joan, she faced her fate with fort.i.tude--fort.i.tude and a supreme faith that her father would succeed in a.n.a.lyzing that sinister orange vapor and find the weapon the world waited for.

But agonizing days pa.s.sed and he did not find it.

Then at last, on the night of August 14th, when Los Angeles and San Francisco were smoldering infernos, along with Reno, Denver, Omaha, El Paso and a score of other great American cities; when Buenos Aires and Santiago were gone, Berlin and Peking and Cairo; when Australia was all one fiery h.e.l.l--then it was that Professor Wentworth summoned Jim Carter to Hartford.

Hoping against hope, he hurried over.

Once again, Joan ushered him into the house. She was very pale and did not speak.

At her side stood her father. It was he who spoke.

"Good evening, Jim. You have come promptly."

His voice was strained, his face grave. He had aged greatly in the past few weeks.

"Well I'll admit I clipped along. You've--found something?"

Professor Wentworth smiled wanly.

"Suppose you step into my study and see what I have found."

He led the way toward the little makes.h.i.+ft laboratory that for many days and nights had been the scene of his efforts.

It was littered with strange devices now, strangest of all perhaps a huge gla.s.s tube like a cannon, mounted on some sort of swivel base.

Ignoring this for the moment, he turned to a smaller tube set upright on a table at the far end of the room. In it, glowed a sinister orange lump that made the whole tube fluorescent.

"Behold one of your monsters in captivity!" said the professor, again with a wan smile. "In miniature, of course. What I have done is to condense some of that vapor into a solid."

The process, he explained, was similar to that employed by Madame Curie in obtaining metallic radium--electrolyzing a radium chloride solution with mercury as a cathode, then driving off the mercury by heat in a current of hydrogen--only he had used the new element instead of radium.

"Incidentally, I have learned that this new element is far more radioactive than radium and possesses many curious properties. Among them, it decomposes violently in water--particularly salt water--producing harmless hydrogen and chloride compounds. So we have nothing to fear from those seeds that fell in our oceans, lakes and rivers."

"Well, that's something, anyway," said Jim. "But have you found any way to combat the ones that have already hatched?"

"Before I answer that question," Professor Wentworth replied, "I shall let you witness a little demonstration."

He advanced to the cannon-like device at the other end of the room, swung it on its swivel till it was pointing directly at that fluorescent orange tube on the table.

"Watch closely!" he said, throwing a switch.

There was a sudden, whining hum in the air and the nib of the big tube glowed a soft, velvety green. Jim gazed at the scene with rapt attention.

"Don't look at that one!" whispered Joan. "Look at the other!"

Jim did so, and saw that its fluorescence was waning.

A moment more the professor held the current on, while the tube grew white. Then he threw off the switch.

"Now let us have a look at our captive," he said, striding over.

They followed, and one glance told Jim what had happened. That sinister lump of orange metal had vanished.

But where was it? That was what he wanted to know.

"A natural question, but not one easy to answer," was Professor Wentworth's reply. "I shall tell you what I have done; then you may judge for yourself."

The cannon-like device which had accompanied the seeming miracle was an adaptation of the cathode tube, whose rays are identical with the beta rays of the atom and consist of a stream of negatively charged particles moving at the velocity of light--186,000 miles a second.

These rays, in theory, have the power to combine with the positively charged alpha rays of the atom and drag them from their electrons, causing them to discharge their full quanta of energy at once, in the form of complete disintegration--and it was this theory the professor had acted on.

"But, good Lord--that's splitting the atom!" exclaimed Jim. "You don't mean to say you've done that?"

"I apparently have," was the grave admission. "But do not let it seem such a miracle. Bear in mind, as I have pointed out before, that nature has accomplished this alchemy many times. All radio-active elements are evidences of it. The feat consists merely in altering the valence of the atom, changing its electric charge, in other words.
