June nudged Max, and Max shrugged indifferently. It wasn't anything a man would pay attention to, perhaps. But June watched Pat for a moment more, then glanced uneasily back to Max. He was eating and listening to Pat's answers and did not feel her gaze. For some reason Max looked almost shrunken to her. He was shorter than she had realized; she had forgotten that he was only the same height as herself. She was dimly aware of the clear lilting chatter of female voices increasing at Pat's end of the table.

"That guy's a menace," Max said, and laughed to himself, cutting another slice of hydroponic mushroom steak. "What's eating you?" he added, glancing aside at her when he noticed her sudden stillness.

"Nothing," she said hastily, but she did not turn back to watching Pat Mead. She felt disloyal. Pat was only a superb animal. Max was the man she loved. Or—was he?

"Go ahead and eat it. It just wouldn't digest. You'd stay hungry."

"Why?" Len was aggrieved.

"Chemical differences in the basic protoplasm of Minos. Different amino linkages, left-handed instead of right-handed molecules in the carbohydrates, things like that. Nothing will be digestible here until you are adapted chemically by a little test-tube evolution. Till then you'd starve to death on a full stomach."

Pat's side of the table had been loaded with the dishes from two trays, but it was almost clear now and the dishes were stacked neatly to one
