“It’s as sharp as a microtome,” he said. “We used one in our lab-remember-for slicing tissue.”

Peter ran the diamond sharpener over the machete, whisking it along the edge. The sharpener was obviously to keep the edge in top condition. “The edge is very fine, so it probably gets dull quickly. But we can sharpen the machete as needed.” The machetes would be useful in cutting a path through vegetation.

Karen King swung a machete around her head. “Nice balance,” she said. “Decent weapon.”

Rick Hutter had stepped backward with alarm as Karen whirled the machete. “You could cut somebody’s head off,” he said to her.

She smirked at him. “I know what I’m doing. You stick to berries and blow-darts.”

“Quit pushing me!” Rick burst out. “What’s your problem?”

Peter Jansen stepped in. Despite their promises to work as a team, it was easier said than done. “Please-Rick-Karen-we’d all appreciate it if you didn’t argue. It’s dangerous for everybody.”

Jenny Linn slapped Rick on the shoulder and said to him, “Karen’s just showing her fear.”

This didn’t sit well with Karen, but she didn’t say anything more. Jenny was right. Karen knew full well that the machetes wouldn’t stop some predators-such as birds, for example. She had been needling Rick because she was afraid. She had revealed her fear to the others, and it embarrassed her. She climbed up the ladder and opened the hatch, and went outdoors to get herself calm. Under the tent, she began investigating the chests that were stored there. She found packets of food in one chest, and many vials and scientific samples in another, probably samples that a team had left behind. She discovered a steel rod, hidden under a tarp. The rod was longer than she was tall. It had a point at one end, while the other end had been enlarged and flattened. For a moment she couldn’t figure out what this enormous metal thing was. Then the scale of the object clicked in her mind, and she knew. She climbed down the ladder and informed the others of what she’d found. “It’s a pin!” she said.

It wasn’t clear what the pin was doing in the tent. Possibly it had been used to pin something to the ground. In any case, the pin was made of steel. It could be shaped into a weapon. “We could use the diamond sharpeners to hone the pin, make it really sharp,” Karen said. “We could put a notch in the tip-that would make a barbed point. A killing point. A barb that would grab in the prey and wouldn’t come loose. A harpoon.”

They had to work on the pin inside the tent, for it was too long to be brought down the ladder. Using the diamond sharpeners, they fell to work cutting and shaping the steel. First they sawed off the flattened head of the pin, which shortened it and gave it better balance, so that a person could hold it and throw it. They took turns filing the point into a notch, to create a barb; the diamond sharpeners worked quickly on the steel. After the work had been done, Peter picked up the harpoon and hefted it. It was a steel pole-massive, gleaming, balanced-yet he handled it as if it weighed almost nothing. In the micro-world, a piece of steel that size was just about heavy enough to do some damage to an insect if you threw it hard and it was sharp enough.

Danny Minot refused to help in any of the preparations. He sat on a bed in the bunker with his arms crossed and knees drawn up, and watched. Peter Jansen felt sorry for him, and went over to him, and said quietly, “Please come with us. You’re not safe here.”

“You said I was the weakest person,” Danny replied.

“We need your help, Danny.”

“For assisted suicide,” he said bitterly, and refused to budge.

Rick Hutter had set about making blow-darts. He went a few paces outside the tent, carrying the machete for protection against ants, and cut several grass stems. Back inside the bunker, he sliced a stem lengthwise, and began stripping out the harder strands of woody material. The grass seemed as tough as bamboo. He shaped the splinters into a couple of dozen darts. The darts still needed to be hardened. He went over to the stove and switched on a coil. He carefully heated and hardened the point of a dart by holding it over the hot coil. When he was finished, he tore open a mattress and pulled out some stuffing.

He needed to fasten a “puff” of soft material to the tail of the blow-dart, so that the dart could be propelled through the tube by a person’s breath. In order to attach this tail-puff to the shaft he needed thread. “Amar-is there any more of that spider silk?”

Amar shook his head. “It got used up saving Peter from the snake.”

No problem. Rick rooted around and found a coil of rope. He cut a short length of the rope, then picked it apart into strands with his fingers. This produced a pile of very strong threads. He held a piece of fluff from the mattress against the end of the dart and wound a thread around it, lashing the tail-puff in place. Now he had a real honest-to-goodness blow-dart-hardened tip, tail-puff, the dart ready to be armed with poison.

Even so, no scientist would assume the dart worked. He would have to test the dart. One of the grass stems, full-length, made a blow tube. Rick fitted the dart into the blow tube, took aim at the wooden frame of a bunk, and blew. The dart zinged across the room, hit the bunk…and bounced off.

“Shit,” he muttered. The dart couldn’t penetrate wood. That meant it would never get through an insect’s exoskeleton, either.

“Fail,” Karen remarked.

“The dart needs a metal tip,” Rick said.

Where to find the metal?

Tableware. Stainless steel tableware. Rick took a steel fork from the kitchen area and bent back one of the fork’s tines. He cut off the tine using the edge of a diamond sharpener, then honed the tine into an exceedingly sharp point. He lashed the steel point to a grass dart, and fired the dart at the bunk. This time, the dart embedded itself in the wood of the bunk with a satisfying thwock, and stayed there, trembling. “Now that will drive into a beetle,” Rick said. One by one, he cut the tines off all the forks in the bunker, until he had created a supply of more than two dozen darts and several blow tubes. He placed the darts in a plastic box he’d found in the lab, to keep them dry and protected from damage.

Rick still had to make curare, but in order to do that he needed to collect more ingredients. Like a fine sauce, a good curare contained a variety of ingredients cooked together, a chemistry of horrors. All he had for an ingredient, at the moment, was the chinaberry, which he’d stored upstairs in the tent. Nobody wanted a toxic chinaberry to be kept inside the bunker. It might give off fumes; it might make them sick. For the same reason, he could not boil curare on the stove. He did not have the ingredients for curare, anyway, and even if he did, everybody could get poisoned if he tried to make curare inside the bunker. The fumes would probably kill them.

He would have to boil curare outdoors over an open fire.

They also turned up a pair of binoculars and two more headlamps, and packed them into the duffels. Amar Singh dug up a roll of duct tape. “We can’t possibly survive in a super-jungle without duct tape,” Amar joked.

Rick Hutter opened a chest and shouted, “A gold mine!” And he pulled out a laboratory apron, rubber gloves, and safety goggles. “This is just what I need for making curare. Excellent, excellent!” He stuffed the things in a duffel bag. He’d have to cook the curare in a vessel of some kind. In the bunker’s tiny kitchen facility, at the bottom of a shelf near the floor, he found a large aluminum pot. He lashed the pot to his duffel pack and then put the pack on his back, testing its weight. He was surprised. The pack, though enormous, felt very light. “I’m as strong as an ant,” Rick said.

Jenny Linn rooted through a supply box and discovered a military compass. The compass, battered and worn, was the type used by American soldiers ever since the Korean War. It could be used to keep them going in a straight line. But none of them could find a GPS unit anywhere at the station.
