At first she--he had early come to think of the being as feminine--had seemed timid, fearful lest her intrusions into his mind prove a nuisance. It took some time for him to assure her that she was always welcome. With time, too, his impression of her grew stronger and more concrete. He found that he was able to visualize her, as he might visualize something remembered, or conceived of in imagination--a lovely young girl, slender and clothed in something loose and filmy, with flowers in her honey-colored hair, and clear blue eyes, a pert, cheerful face, a wide, smiling mouth and an impudently up-tilted nose. He realized that this image was merely a sort of allegorical representation, his own private object-abstraction from a reality which his senses could never picture as it existed. It was about this time that he had begun to call her Dearest. She had given him no name, and seemed quite satisfied with that one. "I've been thinking," she said, "I ought to have a name for you, too. Do you mind if I call you Popsy?" "Huh?" He had been really startled at that. If he needed any further proof of Dearest's independent existence, that was it. Never, in the uttermost depths of his subconscious, would he have been likely to label himself Popsy. "Know what they used to call me in the Army?" he asked. "Slaughterhouse Hampton. They claimed I needed a truckload of sawdust to follow me around and cover up the blood." He chuckled. "Nobody but you would think of calling me Popsy." There was a price, he found, that he must pay for Dearest's companionship--the price of eternal vigilance. He found that he was acquiring the habit of opening doors and then needlessly standing aside to allow her to precede him. And, although she insisted that he need not speak aloud to her, that she could understand any thought which he directed to her, he could not help actually pronouncing the words, if only in a faint whisper. He was glad that he had learned, before the end of his plebe year at West Point, to speak without moving his lips. Besides himself and the kitten, Smokeball, there was one other at "Greyrock" who was aware, if only faintly, of Dearest's presence. That was old Sergeant Williamson, the Colonel's Negro servant, a retired first sergeant from the regiment he had last commanded. With increasing frequency, he would notice the old Negro pause in his work, as though trying to identify something too subtle for his senses, and then shake his head in bewilderment.
