The Spider Goats of Sundown Farm

The goat was named Henrietta, and she did not look like she contained anything strange at all.

"She looks like a goat," Maya said.

"She is a goat," said Soren. He was reading the laminated card zip-tied to the fence. "Mostly."

"Mostly?"

"That's what it says. It says ninety nine point something percent goat."

Maya leaned on the rail. "And the other point something?"

Soren turned the card over, but the back was blank. The woman who owned the farm, Dr. Okafor, had told them she would explain at milking time and then had walked off to fix a water pump and not come back for two hours. She was the kind of person who answered a question with see for yourself, which Maya liked and Soren found mildly unfair.

They filled the feed troughs. They forked out the old straw. Henrietta watched them with her sideways rectangle eyes and chewed.

"Spider," Maya said suddenly.

"What?"

"The point something. I bet it's spider."

Soren put down the fork. "You're guessing."

"There's a poster in the barn. Big orange spider. I saw it when we came in."

They went and looked. The poster was old and curling at the corners. A golden orb weaver sat in the middle of its web, and under it someone had written, by hand, in fading marker: she makes a thread thinner than this sentence and you cannot break it with your hands.

"Okay," Soren said slowly. "But a spider is a spider and a goat is a goat. You can't just put one inside the other."

"Why not?"

"Because." He stopped. He was honest about the moment a because ran out. "I don't actually know why not."

Dr. Okafor came in then, wiping her hands on a rag, and she had heard the last part.

"You can," she said. "You put in the instructions. Not the spider. Just one instruction out of the spider's whole book."

"The instruction for the thread," Maya said.

"The instruction for the protein the thread is made of." Dr. Okafor pulled up a stool by Henrietta and showed them how to milk, two fingers and a thumb, squeeze from the top. "A spider builds silk out of a protein. There's a stretch of code that tells a cell how to make that protein. We copied that stretch. We put it where Henrietta's body would read it when she makes milk."

The milk came out into the steel pail. It looked like milk. White. Ordinary.

Maya stared at it. "It's in there."

"It's in there."

"You can't see it."

"You can't see it," Dr. Okafor agreed. "It's dissolved. Smaller than anything your eye is built for. You'd need to pull it out and dry it and spin it before it becomes anything you could hold."

Soren was quiet, and then he asked the question he needed before he could believe the rest. "How do you spin milk into thread?"

"Carefully," Dr. Okafor said, and laughed, and went to answer the phone, which had started ringing in the house, and once again did not come back.

The two of them sat with the pail.

"Stronger than steel," Maya said. "That's what the other card said. By weight. A thread of it the same weight as a steel wire, the silk one holds more."

"From milk," Soren said.

"From milk."

He dipped his finger in and rubbed it against his thumb. Just milk. Warm. Slightly sweet smelling. Nothing in it that announced itself.

"Here's what gets me," Maya said. She had her thinking voice on, short and flat. "The spider isn't doing anything magic. It eats bugs. It makes a protein. The instruction is just a long word spelled in chemicals."

"A recipe."

"A recipe you can copy out and hand to something completely different. And the goat just. Reads it. The goat doesn't know it's a spider recipe. The goat can't read. It just runs the instruction."

Soren looked at Henrietta, who burped.

"So the recipe works in anything," he said. "That's the part. It's not a goat recipe or a spider recipe. It's just a recipe, and the spider and the goat are both. machines that follow it."

"Same machines," Maya said.

They both looked at the poster spider, then at the goat, then at their own hands.

"Same machines," Soren said again, and his voice had gone careful, "The spider and the goat and the. us. We all read the same kind of code. That's why you can move a line of it from one to the other. It would be like." He searched. "Like if every animal on earth ran on the same language and nobody ever told us."

"Nobody told us because nobody had to," Maya said. "It was always like that. The spider was always a sentence you could read out loud somewhere else."

Soren took out his notebook. He drew a spider on the left and a goat on the right and a single line running between them, and along the line he wrote four letters, over and over, in the order Dr. Okafor had not given them but that he knew was real, the four letters everything is spelled in.

Maya watched the pail. "There's a thread in there," she said. "Not spun yet. But it's already a thread. It's just waiting to be pulled out long."

"It's a thread that was a spider's idea," Soren said.

"It's a thread that was a spider's idea, coming out of a goat, that we could hold up and not break with our hands." Maya stood up. She was looking at the barn now, at the straw and the troughs and the other goats, all of them ninety nine point something, every one of them carrying one borrowed sentence and not knowing it. "Soren. If you can move that line. you can move any line."

Neither of them said the next part, which was about how many lines there were, and in how many living things, and that all of them might be movable.

Henrietta turned her head and looked straight at Maya with her strange rectangle eye.

The milk in the pail caught the barn light and went on looking exactly like milk.
