"Excuse me, miss," he said doubtfully, "but are you the librarian?"
"My God," exclaimed the girl, "don't tell me you want a book!"
"Why, yes," he replied, uncertainty in his voice. "Isn't this the library?"
"It's the library, yes. But I've been in this vault for a month now, and you're the first person who's asked for a book. I'd rather be back at the factory."
"You used to work in a factory?"
The girl nodded. "Where they make the paralysis ray insulators."
"The green suits?" he ejaculated.
"Yes. They're green. Why?"
"No reason," he replied cautiously. "Do you have any volumes on botany, horticulture, plant growth, anything at all related to that subject?"
Her gray eyes opened wide. "How long have you been here?"
