"You're right, Bella," agreed Harper incisively. "I'll go and find out for myself. Immediately!" Scooping up his hat, he left at his usual lope. "Well!" remarked his sister. "All I can say is that they'd better turn that happy-gas on extra strong for Harp's trip out!" * * * * * The trip out did Harper a world of good. Under the influence of the soporific gas that permeated the rocket, he really relaxed for the first time in years, sinking with the other passengers into a hazy lethargy with little sense of passing time and almost no memory of the interval. It seemed hardly more than a handful of hours until they were strapping themselves into deceleration hammocks for the landing. And then Harper was waking with lassitude still heavy in his veins. He struggled out of the hammock, made his way to the airlock, and found himself whisked by pneumatic tube directly into the lobby of the Emerald Star Hotel. Appreciatively he gazed around at the half-acre of moss-gray carpeting, green-tinted by the light sifting through the walls of Martian copper-glass, and at the vistas of beautiful domed gardens framed by a dozen arches. But most of all, the robots won his delighted approval. He could see at once that they had been developed to an amazingly high state of perfection. How, he wondered again, had this been done without his knowledge? Was Scrib right? Was he slipping? Gnawing at the doubt, he watched the robots moving efficiently about, pushing patients in wheelchairs, carrying trays, guiding newcomers, performing janitorial duties tirelessly, promptly, and best of all, silently. Harper was enthralled. He'd staff his offices with them. Hang the expense! There'd be no more of that obnoxious personal friction and proneness to error that was always deviling the most carefully trained office staffs! He'd investigate and find out the exact potentialities of these robots while here, and then go home and introduce them into the field of business. He'd show them whether he was slipping! Briskly he went over to the desk. He was immediately confronted with a sample of that human obstinacy that was slowly driving him mad. Machines, he sighed to himself. Wonderful silent machines! For a woman was arguing stridently with the desk clerk who, poor man, was a high strung fellow human instead of a robot. Harper watched him shrinking and turning pale lavender in the stress of the argument. "A nurse!" shouted the woman. "I want a nurse! A real woman! For what you charge, you should be able to give me a television star if I want one! I won't have another of those damnable robots in my room, do you hear?"
