demands to the rest.
The ever-hungry body screamed for more food, faster!
Now that it had reached a fairly efficient size, it was fully awake. It puzzled over the energy-impressions around it, locating the source of the new food massed in one spot.
Effortlessly it pushed itself into the air, flew a little way and dropped on the food. Its super-efficient cells eagerly gulped the rich radioactive substances. But it did not ignore the lesser potentials of metal and clumps of carbohydrates.
'The damned fools,' General O'Donnell said. 'Why did they have to panic? You'd think they'd never been trained.' He paced the ground outside his tent, now in a new location three miles back.
The leech had grown to two miles in diameter. Three farming communities had been evacuated.
Micheals, standing beside the general, was still stupefied by the memory. The leech had accepted the massed power of the weapons for a while, and then its entire bulk had lifted in the air. The Sun had been blotted out as it flew leisurely over North Hill, and dropped. There should have been time for evacuation, but the frightened soldiers had been blind with fear.
Sixty-seven men were lost in Operation Leech, and General O'Donnell asked permission to use atomic bombs. Washington sent a group of scientists to investigate the situation.
'Haven't those experts decided yet?' O'Donnell asked, halting angrily in front of the tent. 'They've been talking long enough.'
'It's a hard decision,' Micheals said. Since he wasn't an official member of the investigating team, he had given his information and left. 'The physicists consider it a biological matter, and the biologists seem to think the chemists should have the answer. No one's an expert on this, because it's never happened before. We just don't have the data.'
'It's a military problem,' O'Donnell said harshly. 'I'm not interested in what the thing is—I want to know what can destroy it. They'd better give me permission to use the bomb.'
Micheals had made his own calculations on that. It was impossible to say for sure, but taking a flying guess at the leech's mass-energy absorption rate, figuring in its size and apparent capacity for growth, an atomic bomb
He estimated three days as the limit of usefulness. The leech was growing at a geometric rate. It could cover the United States in a few months.
'For a week I've been asking permission to use the bomb,' O'Donnell grumbled. 'And I'll get it, but not until after those jackasses end their damned talking.' He stopped pacing and turned to Micheals. 'I am going to destroy the leech. I am going to smash it, if that's the last thing I do. It's more than a matter of security now. It's personal pride.'
That attitude might make great generals, Micheals thought, but it wasn't the way to consider this problem. It was anthropomorphic of O'Donnell to see the leech as an enemy. Even the identification, 'leech,' was a humanizing factor. O'Donnell was dealing with it as he would any physical obstacle, as though the leech were the simple equivalent of a large army.
But the leech was not human, not even of this planet, perhaps. It should be dealt with in its own terms.
'Here come the bright boys now,' O'Donnell said.
From a nearby tent a group of weary men emerged, led by Allenson, a government biologist.
'Well,' the general asked, 'have you figured out what it is?'
'Just a minute, I'll hack off a sample,' Allenson said, glaring through red-rimmed eyes.
'Have you figured out some
'Oh, that wasn't too difficult,' Moriarty, an atomic physicist, said wryly. 'Wrap it in a perfect vacuum. That'll do the trick. Or blow it off the Earth with anti-gravity.'
'But failing that,' Allenson said, 'we suggest you use your atomic bombs, and use them fast.'
'Is that the opinion of your entire group?' O'Donnell asked, his eyes glittering.
'Yes.'
The general hurried away. Micheals joined the scientists.
'He should have called us in at the very first,' Allenson complained. 'There's no time to consider anything but force now.'
'Have you come to any conclusions about the nature of the leech?' Micheals asked.
'Only general ones,' Moriarty said, 'and they're about the same as yours. The leech is probably extraterrestrial in origin. It seems to have been in a spore-stage until it landed on Earth.' He paused to light a pipe. 'Incidentally, we should be damned glad it didn't drop in an ocean. We'd have had the Earth eaten out from under us before we knew what we were looking for.'
They walked in silence for a few minutes.
'As you mentioned, it's a perfect converter—it can transform mass into energy, and any energy into mass.' Moriarty grinned. 'Naturally that's impossible and I have figures to prove it.'
'I'm going to get a drink,' Allenson said. 'Anyone coming?'
'Best idea of the week,' Micheals said. 'I wonder how long it'll take O'Donnell to get permission to use the bomb.'
'If I know politics,' Moriarty said, 'too long.'
The findings of the government scientists were checked by other government scientists. That took a few days. Then Washington wanted to know if there wasn't some alternative to exploding an atomic bomb in the middle of New York State. It took a little time to convince them of the necessity. After that, people had to be evacuated, which took more time.
Then orders were made out, and five atomic bombs were checked out of a cache. A patrol rocket was assigned, given orders, and put under General O'Donnell's command. This took a day more.
Finally, the stubby scout rocket was winging its way over New York. From the air, the grayish-black spot was easy to find. Like a festered wound, it stretched between Lake Placid and Elizabethtown, covering Keene and Keene Valley, and lapping at the edges of Jay.
The first bomb was released.
It had been a long wait after the first rich food. The greater radiation of day was followed by the lesser energy of night many times, as the leech ate away the earth beneath it, absorbed the air around it, and grew. Then one day—
An amazing burst of energy!
Everything was food for the leech, but there was always the possibility of choking. The energy poured over it, drenched it, battered it, and the leech grew frantically, trying to contain the titanic dose. Still small, it quickly reached its overload limit. The strained cells, filled to satiation, were given more and more food. The strangling body built new cells at lightning speed. And—
It held. The energy was controlled, stimulating further growth. More cells took over the load, sucking in the food.
The next doses were wonderfully palatable, easily handled. The leech overflowed its bounds, growing, eating, and growing.
That was a taste of real food! The leech was as near ecstasy as it had ever been. It waited hopefully for more, but no more came.
It went back to feeding on the Earth. The energy, used to produce more cells, was soon dissipated. Soon it was hungry again.
It would always be hungry.
O'Donnell retreated with his demoralized men. They camped ten miles from the leech's southern edge, in the evacuated town of Schroon Lake. The leech was over sixty miles in diameter now and still growing fast. It lay sprawled over the Adirondack Mountains, completely blanketing everything from Saranac Lake to Port Henry, with one edge of it over Westport, in Lake Champlain.
Everyone within two hundred miles of the leech was evacuated.
General O'Donnell was given permission to use hydrogen bombs, contingent on the approval of his scientists.
'What have the bright boys decided?' O'Donnell wanted to know.
He and Micheals were in the living room of an evacuated Schroon Lake house. O'Donnell had made it his new
