The Green Brain

THE MILLION-IN-ONE MAN
The extermination engineers had erected barriers between the Red and the Green zones. In the Green, the men had done their work well—no useless insects survived. But they still had to clear the way in the Red zone, to destroy insect life there—a lower form of life which was presenting a threat to mankind.
The Indian waited at the barrier to be let into the Green zone; he simulated the servility which would identify him as a primitive from the deep Brazilian interior—from the Red zone.
At the barrier he was almost overcome with the repellants sprayed at him. But the brilliant facets of his eyes, the tiny scales of his skin were not detected. The weave of furry separate cells did not become unraveled.
The million-in-one man penetrated the uninfested Green.
