Grizzly bears, before the white man came, were so scornful of man that they could be considered the dominant species in North America. They'd been known to raid a camp of Indians to carry away a man for food. Indian spears and arrows were simply ineffective against them. When Stonewall Jackson was a lieutenant in the United States Army, stationed in the West to protect the white settlers, he and a detachment of mounted troopers were attacked without provocation by a grizzly who was wholly contemptuous of them. The then Lieutenant Jackson rode a horse which was blind in one eye, and he maneuvered to get the bear on the horse's blind side so he could charge it. With his cavalry sabre he split the grizzly's skull down to its chin. It was the only time in history that a grizzly bear was ever killed by a man with a sword. But no grizzly nowadays would attack a man unless cornered. Even cubs with no possible experience of humankind are terrified by the scent of men.
All that was true enough. In addition, preparations for the Park included much activity by the Wild Life Control unit, which persuaded bears to congregate in one area by putting out food for them, and took various other measures for deer and other animals. It had seeded trout streams with fingerlings and the lake itself with baby big-mouthed bass. The huge trailer truck of Wild Life Control was familiar enough. Lockley had seen it headed up to the lake the day before the landing. Now he found himself wondering sardonically to what degree the Wild Life Control men determined where mountain lions should hunt.
He'd slept in the open innumerable times without thinking of mountain lions. With Jill to look after, though, he worried. But he was horribly weary, and he knew somehow that in the back of his mind there was something unpleasant that was trying to move into his conscious thoughts. It was a sort of hunch. Wearily and half asleep, he tried to put his mind on it. He failed.
He awoke suddenly. There were rustlings among the trees. Something moved slowly and intermittently toward him. It could be anything, even a creature from Boulder Lake. He heard other sounds. Another creature. The first drew near, not moving in a straight line. The second creature followed it, drawing closer to the first.
Lockley's scalp crawled. Creatures from space might have some of the highly-developed senses which men had lost while growing civilized—full keenness of scent, for example.
Such a creature might be able to find Lockley and Jill in the darkness after trailing them for miles. And so primitive a talent, in a creature farther advanced than men, was somehow more horrifying than anything else Lockley had thought of about them. He gripped his club desperately, wholly aware that a star creature should be able to paralyze him with the terror beam....
There were whistling, squealing noises. They were very much like the squeaks his captors had directed at each other and at him when he was blindfolded and being led downhill to imprisonment in the compost pit shell. Very much like, but not identical. Nevertheless, Lockley's hair seemed to stand up on end and he raised his club in desperation.
The whistling squeals grew shriller. Then there was an indescribable sound and one of the two creatures rushed frantically away. It traveled in great leaps through the blackness under the trees.
And then there was a sudden whiff of a long-familiar odor, smelled a hundred times before. It was the reek of a skunk, stalked by a carnivore and defending itself as skunks do. But a skunk was nothing like a terror beam. Its effluvium offended only one sense, affected only one set of sensation nerves. The terror beam....
Lockley opened his mouth to laugh, but did not. The thing at the back of his mind had come forward. He was appalled.
Jill said shakily, "What's the matter? What's happened? That smell—"
"It's only a skunk," said Lockley evenly. "He just told me some very bad news. I know how the terror beam works now. And there's not a thing that can be done about it. Not a thing. It can't be!"
He raged suddenly, there in the darkness, because he saw the utter hopelessness of combatting the creatures who'd taken over Boulder Lake. There was nothing to keep them from taking over the whole earth, no matter what sort of monsters or not-monsters they might be.
CHAPTER 6
It was nine o'clock at night when Lockley killed the porcupine, and ten by the time Jill had gone back to sleep huddled between the projecting roots of a giant tree. Shortly after midnight Lockley had been awakened when a skunk defeated a hungry predator within a hundred yards of their bivouac. But some time in between, there was another happening of much greater importance elsewhere.
Something came out of Boulder Lake National Park. All humans had supposedly fled from it. It was abandoned to the creatures of the thing from the sky. But something came out of it.
Nobody saw the thing, of course. Nobody could approach it, which was the point immediately demonstrated. No human being could endure being within seven miles of whatever it was. It was evidently a vehicle of some sort, however, because it swung terror beams before it, and terror beams on either side, and when it was clear of the Park it played terror beams behind it, too. Men who suffered the lightest touch of those sweeping beams of terror and anguish moved frantically to avoid having the experience again. So when something moved out of the Park and sent wavering terror beams before it, men moved to one side or the other and gave it room.
On a large-scale map in the military area command post, its progress could be watched as it was reported. The reports described a development of unbearable beam strength which showed up as a bulge in the cordon's roughly circular line. That bulge, which was the cordon itself moving back, moved outward and became a half-circle some miles across. It continued to move outward, and on the map it appeared like a pseudopod extruded by an enormous amoeba. It was the area of effectiveness of a weapon previously unknown on earth—the area where humans could not stay.
Deliberately, the unseen moving thing severed itself from the similar and larger weapon field which was its birthplace and its home. It moved with great deliberation toward the small town of Maplewood, twenty miles from the border of the Park.
Jeeps and motorcycles scurried ahead of it, just out of reach of its beams. They made sure that houses and farms and all inhabited places were emptied of people before the moving terror beams could engulf them. They went into the town of Maplewood itself and frantically made sure that nothing alive remained in it. They went on to clear the countryside beyond.
The unseen thing from the Park moved onward. High overhead there was a dull muttering like faraway thunder, but it was planes with filled bomb racks circling above the starlit land. There were men in those planes who ached to dive down and destroy this separated fraction of an invasion. But there were firm orders from the Pentagon. So long as the invaders killed nobody, they were not to be attacked. There was reason for the order in the desire of the government to be on friendly terms with a race which could travel between the stars. But there was an even more urgent reason. The aliens had not yet begun to murder, but it was suspected that they had a horrifying power to kill. So it was firmly commanded that no bomb or missile or bullet was to be used unless the invaders invited hostilities by killing humans. Their captives—the crew of a helicopter—might be freed if aliens and men achieved friendship. So for now—no provocation!
The thing which nobody saw moved comfortably over the ground between the park and Maplewood. In the center of the weapon field there was a something which generated the terror beam and probably carried passengers. Whatever it was, it moved onward and into Maplewood and for seven miles in every direction troops watched for it to move out again. Artillerymen had guns ready to fire upon it if they ever got firing coordinates and permission to go into action. Planes were ready to drop bombs if they ever got leave to do so. And a few miles away there were rockets ready to prove their accuracy and devastating capacity if only given a launching command. But nothing happened. Not even a flare was permitted to be dropped by the planes far up in the sky. A flare might be taken for hostility.
