"No, you won't do anything like that." Luck's voice had a disturbing note of absolute finality. Bill looked at him sidelong. "A fellow can't work forever without sleep. My head's splitting right now. I can hardly see--" "Yes, you can see well enough to do your work--and do it right! Get that?" Bill grunted. Evidently he got it, for he said no more about his head, or about sleep. He did glance frequently out of the tail of his eye at Luck's absorbed face with his jaw set at a determined angle and his great mop of iron-gray hair looking like a heavy field of grain after a thunderstorm, standing out as it did in every direction. Now and then Luck pushed it back impatiently with the flat of his palm, but he showed no other sign of being conscious of anything at all save the picture; though he could have told you offhand just how many times Bill turned his eyes upon him. At noon they were not through, and to Bill the attempt to finish that day seemed hopeless, not to say insane. But by four o'clock they were done with the cutting and joining, and had their film carefully packed and in the mountain wagon, and were ready to drive through the slushy mud which was the aftermath of the blizzard to the little house in Albuquerque which the boys had turned into a crude but efficient laboratory. There Luck continued to be merciless in his driving energy. He canvassed the moving-picture theaters of the town and borrowed reels on which to wind his film when it was once ready for winding. He went back to the little house and set every one within it to work and kept them at it. He printed his positive, dissolved his aniline dye, which was to be firelight effect, in the bathtub,--and I should like to know what the landlord thought when next he viewed that tub! He made an orange bath for sunrise effects in one of the stationary tubs, and his light blue for night tints in the other. He buzzed around in that little house like a disturbed blue-bottle fly that cannot find an open window. He had his sleeves rolled to his shoulders and his hair more tousled than ever; he had blue circles under his eyes and dabs of dye distributed here and there on his face and his arms; he had in his eyes the glitter of a man who means to be obeyed instantly and implicitly, whatever his command may be,--and if you want to know, he was obeyed in just that manner.
