Estevez flinched from the day sky. And Estevez admit to his fear? Retreat from it? Not if he had to go back in and throw up, after his glance at the weather. Allergies, Estevez said.
And it was funny, but it wasn’t, since Estevez couldn’t leave this world. Steroids weren’t the long-term answer, and they hadn’t had an immune response problem in a hundred years and more on-station. Gene-patching wasn’t an option for their little earth-sciences/chemistry lab down on the planet, they couldn’t send specimens Upstairs, they hadn’t anybody trained to run the equipment if they could get it down here, they weren’t a hundred percent sure a gene-patch was what they ought to try under exotic circumstances, anyway, and, meanwhile, Archive had come up with an older, simpler idea: find the substance. Try desensitization.
Fine, Estevez said, sleepless with steroids, stuck with needles, patched with tape, experimented on by botanists and zoologists. He’d try anything. Meanwhile Estevez stayed under filtration and stayed comfortable and maintained his sense of humor—except it was scary to react to something after two months down here. The medics thought it should take longer. They weren’t sure. There’d never been a hundred-fifty-year-old genetically isolated, radiation-stressed human population exposed to an alien world. Not in their records.
Wonderful, said Estevez.
Meanwhile all of them who went out on Survey, laying down their little grids of tape and counting grass species, took careful specimens of anything new, bushes, grasses, seeding and sporing plants and fungi and the like. The medics waved a part of that sample past Estevez‘ nose and taped other samples to his skin. They hung simple adhesive strips in the wind, and counted what impacted them, and analyzed snips of the filters, figuring at first that whatever Estevez was reacting to had to be airborne. But they were working on a new theory now, and analyzed samples of soil and dead grasses, looking for molds.
So they added the soil punch to the regular test, and extended the grid of samples beyond the sterilized ground. Ian took a soil sample every hundred meters, a punch of a plastic tube down past the root-line, and left his blue plastic tube inserts in a row down the hillside, to pick up on the way back. The old hands down here could walk briskly. He ambled, stopped often, lungs aching, on the long easterly climb uphill, into the rising sun.
He’d spotted different color on the east hill yesterday. It looked like a blooming plant, and if it did bloom, in the economy of nature, one could guess it did that to put forth genetic material for sexual combination to produce seed, as the grasses did, a likely and advantageous system according to their own Earthly prejudice.
That indicated, then, that it was shedding something into the air, and if it was shedding something, one might well argue it was pollen. The committee was still arguing the matter—quasi-pollen or quasi-spores from quasi-flowers, but ask Estevez if he cared. The reproduction of the broadleaf grasses might need debate, and possibly a new nomenclature, but those looked to him like flowers of the sort they grew in the herbarium from Earth seed, red-violet, specifically, different than anything they had yet seen in the landscape.
And sweet-smelling, deliciously sweet, once he’d climbed far enough up the hill to catch the scent, and to take his whole-plant sample.
Stowing that, with best hopes for Estevez, he drew his square, pegging one-meter lines on a plastic grid, took up his handheld recorder, and began counting ordinary grasses—there was a type, Lawton argued, that, with 136 grains per ear on average, showed evidence of artificial selection, probably had drifted from cultivated fields, and that that might let them, at safe distance, gather information on the edibility for humans of what the natives cultivated.
Which would tell them—
A siren blasted out abruptly, down among the base buildings. Ian froze, sitting as he was, looked downhill and looked about him, thinking some surveyor across the valley must have misjudged his position and triggered the perimeter alarm.
Grass near him whispered out of time with the breeze.
Startled, he spun on one knee and found himself staring at a pair of brown, dusty boots, and the hem of a brown, knee-length, many-buttoned coat, and the tall perspective of an ebon-skinned giant.
