"Only with a gun."

"We can't waste ammo on that."

"No." Rod thought about it, then went to a pile of bamboo poles, cut for building. He selected a stout one a head shorter than himself, sat down and began to bind Lady Macbeth to it with rawhide, forming a crude pike spear.

Caroline came over and squatted down. "What are you doing?"

"Making a joe-killer."

She watched him. "I'm going to make me one," she said suddenly and jumped up.

By daylight the animals were in full flight downstream as if chased by forest fire. As the creek had shrunk with the dry season a miniature beach, from a meter to a couple of meters wide, had been exposed below the bank on which the town had grown. The thorn kraal had been extended to cover the gap, but the excited animals crushed through this weak point and now streamed along the water past the camp.

After a futile effort no attempt was made to turn them back. They were pouring into the valley; they had to go somewhere, and the route between water and bank made a safety valve. It kept them from shoving the barricade aside by sheer mass. The smallest animals came through it anyhow, kept going, paid no attention to humans.

Rod stayed at the barricade, ate breakfast standing up. He had killed six joes since dawn while Caroline's score was still higher. Others were making knives into spears and joining them. The dopy joes were not coming through in great numbers; most of them continued to chase buck along the lower route past camp. Those who did seep through were speared; meeting them with a knife gave away too much advantage.

Cowper and Kennedy, inspecting defenses, stopped by Rod; they looked worried. "Rod," said Grant "how long is this going to last?"

"How should I know? When we run out of animals. It looks like- get him, Shorty! It looks as if the joes were driving the others, but I don't think they are. I think they've all gone crazy."

"But what would cause that?" demanded Kennedy. "Don't ask me. But I think I know where all those bones on that beach came from. But don't ask why. Why does a chicken cross the road? Why do lemmings do what they do? What makes a plague of locusts? Behind you! Jump!"

Kennedy jumped, Rod finished off a joe, and they went on talking. "Better detail somebody to chuck these into the water, Bill, before they stink. Look, Grant, we're okay now, but I know what I would do."

"What? Move to your caves? Rod, you were right-but it's too late."

"No, no! That's spilt milk; forget it. The thing that scares me are these mean little devils. They are no longer dopy; they are fast as can be and nasty... and they can slide through the fence. We can handle them now-but how about when it gets dark? We've got to have a solid line of fire inside the fence and along the bank. Fire is one thing they can't go through... I hope."

"That'll take a lot of wood." Grant looked through the barricade and frowned.

"You bet it will. But it will get us through the night. See here, give me the ax and six men with spears. I'll lead the party."

Kennedy shook his head. "It's my job."

"No, Bill," Cowper said firmly. "I'll lead it. You stay here and take care of the town."

Before the day was over Cowper took two parties out and Bill and Rod led one each. They tried to pick lulls in the spate of animals but Bill's party was caught on the bluff above, where it had been cutting wood and throwing it down past the cave. They were treed for two hours. The little valley had been cleaned out of dead wood months since; it was necessary to go into the forest above to find wood that would burn.

Cliff Pawley, hunter-in-chief, led a fifth party in the late afternoon, immediately broke the handle of the little ax. They returned with what they could gather with knives. While they were away one of the giant buck they called buffalo stampeded off the bluff, fell into camp, broke its neck. Four dopy joes were clinging to it. They were easy to kill as they would not let go.

Jimmy and Rod were on pike duty at the barricade. Jimmy glanced back at where a couple of girls were disposing of the carcasses. "Rod," he said thoughtfully, we got it wrong. Those are stobor... the real stobor."

"Huh?"

"The big babies we've been calling that aren't 'stobor.' These things are what the Deacon warned us against."

"Well... I don't care what you call them as long as they're dead. On your toes, boy; here they come again."

Cowper ordered fires laid just before dark and was studying how to arrange one stretch so as not to endanger the flume when the matter was settled; the structure quivered and water ceased to flow. Upstream something had crashed into it and broken the flimsy pipe line.

The town had long since abandoned waterskins. Now they were caught with only a few liters in a pot used by the cooks, but it was a hardship rather than a danger; the urgent need was to get a ring of fire around' them. There had already been half a dozen casualties- no deaths but bites and slashings, almost all from the little carnivores contemptuously known as dopy joes. The community's pool of antiseptics, depleted by months of use and utterly irreplaceable, had sunk so low that Bob Baxter used it only on major wounds.

When fuel had been stretched ready to burn in a long arc inside the barricade and down the bank to where it curved back under the cave, the results of a hard day's work looked small; the stockpile was not much greater than the amount already spread out. Bill Kennedy looked at it. "It won't last the night, Grant."

"It's got to, Bill. Light it."

"If we pulled back from the fence and the bank, then cut over to the bluff- what do you think?"

Cowper tried to figure what might be saved by the change. "It's not much shorter. Uh, don't light the downstream end unless they start curving back in on us. But let's move; it's getting dark." He hurried to the cooking fire, got a brand and started setting the chain of fire. Kennedy helped and soon the townsite was surrounded on the exposed sides by blaze. Cowper chucked his torch into the fire and said, "Bill, better split the men into two watches and get the women up into the cave- they can crowd in somehow."

"You'll have trouble getting thirty-odd women in there, Grant."

"They can sit up all night. But send them up. Yes, and the wounded men, too."

"Can do." Kennedy started passing the word. Caroline came storming up, spear in hand

"Grant, what's this nonsense about the girls having to go up to the cave? If you think you're going to cut me out of the fun you had better think again!"

Cowper looked at her wearily. "Carol, I haven't time to monkey. Shut your face and do as you are told."

Caroline opened her mouth, closed it, and did as she was told. Bob Baxter claimed Cowper's attention; Rod noticed that he looked very upset. "Grant? You ordered all the women up to the cave?"

"Yes."

"I'm sorry but Carmen can't."

"You'll have to carry her. She is the one I had most on my mind when I decided on the move.

"But-" Baxter stopped and urged Grant away from the others. He spoke insistently but quietly. Grant shook his head.

"It's not safe, Grant," Baxter went on, raising his voice. "I don't dare risk it. The interval is nineteen minutes now.

"Well... all right. Leave a couple of women with her. Use Caroline, will you? That'll keep her out of my hair."

"Okay." Baxter hurried away.

Kennedy took the first watch with a dozen men spread out along the fire line; Rod was on the second watch commanded by Cliff Pawley. He went to the Baxter house to find out how Carmen was doing, was told to beat it by Agnes. He then went to the bachelors' shed and tried to sleep.

He was awakened by yells, in time to see one of the leonine monsters at least five meters long go bounding through the camp and disappear downstream. It had jumped the barrier, the stakes behind it, and the fire behind that, all in one leap.
