"And there's the Flat. It lies level with the ground, and not much higher. It can wrap you like a blanket."
"I could see, but he couldn't, as around from behind the corner of the desrick flowed something. It lay out on the ground like a broad, black, short-furred carpet rug. But it moved, humping and then flattening out, the way a measuring worm moves. It moved pretty fast, right toward Mr. Yandro from behind and to one side."
"The crawling carpet brushed its edge against his foot. He looked down at it, and his eyes stuck out all of a sudden, like two door knobs. He knew what it was, and named it at the top of his voice. 'The Flat!' Humping against him, it tried to wrap around his foot and leg."
