The infants were unloaded.
"Now turn them so that they can see the flowers and books." [...]
The Director rubbed his hands. "Excellent!" he said. "It might almost have been done on purpose."

They were predestined to emigrate to the tropics, to be miner and acetate silk spinners and steel workers. Later on their minds would be made to endorse the judgment of their bodies. "We condition them to thrive on heat," concluded Mr. Foster. "Our colleagues upstairs will teach them to love it."
