A third hand went up. A slender hand that was instantly recognized as that of Dr. Edith Ward.

"I wish to clarify a point," she said. "Mr. Barden's logic is impeccable, but it is based upon one false premise."

Barden looked at the woman carefully. No one could call her beautiful, but there was a womanly charm about her that was in sharp contrast to the cold facts she held in her brain. She looked about thirty years old, which included the mental adjustment necessary to compare her with a younger woman. That she was the head of the Solar Space Laboratory was in itself a statement of her ability as a physicist.

"I believe that my own belief is as firm as Miss Ward's," retorted Barden.

"You will find that your premise may be valid, but the end-result is not profitable," she said flatly.

"You've experimented?" scoffed Barden.

"I don't have to," she said. "I know!"

"Perhaps by feminine intuition?" snapped Tom scathingly.
