"They say for a little extra you can get an exact resemblance. Maybe I'd better have one fixed up like you to take back with me," Big Tom added teasingly. Then as Helen's face clouded over, "Oh, hon, you know I was only kidding. Let's get out of here; this place gives me the collywobbles. Besides, I've got to pick up my watch." But his mother's face was still unhappy and Tommy glowered sullenly at his father's back all the way to the watch-shop. It was a small shop, with an inconspicuous sign down in one corner of the window that said only, "KRUMBEIN--watches," and was probably the most famous shop of its kind in the world. Every spaceman landing on Terra left his watch to be checked by the dusty, little old man who was the genius of the place. Tommy ranged wide-eyed about the clock and chronometer crammed interior. He stopped fascinated before the last case. In it was a watch ... but, _what_ a watch! Besides the regulation Terran dial, it had a second smaller dial that registered the corresponding time on Mars. Tommy's whole heart went out to it in an ecstasy of longing. He thought wistfully that if you could know what time it was there, you could imagine what everyone was doing and it wouldn't seem so far away. Haltingly, he tried to explain. "Look, Mom," he said breathlessly. "It's almost five o'clock at home. Douwie will be coming up to the barn to be fed. Gosh, do you suppose old Pete will remember about her?" His mother smiled at him reassuringly. "Of course he will, silly. Don't forget he was the one who caught and tamed her for you." Tommy gulped as he thought of Douwie. Scarcely as tall as himself; the big, rounded, mouselike ears, and the flat, cloven pads that could carry her so swiftly over the sandy Martian flatlands. One of the last dwindling herds of native Martian douwies, burden-carriers of a vanished race, she had been Tommy's particular pride and joy for the last three years. Behind him, Tommy heard his mother murmur under her breath, "Tom ... the watch; _could_ we?" And his Dad regretfully, "It's a pretty expensive toy for a youngster, Helen. And even a _rabbara_ raiser's bank account has limits." "Of course, dear; it was silly of me." Helen smiled a little ruefully. "And if Mr. Krumbein has your watch ready, we _must_ go. Bee and some of her friends are coming over, and it's only a few hours 'till you ... leave." Big Tom squeezed her elbow gently, understandingly, as she blinked back quick tears. Trailing after them, Tommy saw the little by-play and his heart ached. The guilt-complex building up in him grew and deepened. He knew he had only to say, "Look, I don't mind staying. Aunt Bee and I will get along swell," and everything would be all right again. Then the terror of this new and complex world--as it would be without a familiar face--swept over him and kept him silent.
