It was hard to change places in the sealed cabin of the cat, but they were successful, and Ross took the wheel gingerly. Following Kurt's directions, he started ahead, his eyes focused on the light rather than the white expanse before him. And after a few minutes of strain he caught the hang of it. As Kurt had promised, it was very simple. After watching him for a while, his instructor gave a grunt of satisfaction and settled down for a nap. Once the first excitement of driving the cat wore off, the operation tended to become monotonous. Ross caught himself yawning, but he kept at his post with dogged stubbornness. This had been Kurt's game all the way through--so far--and he was certainly not going to resign his first chance to show that he could be of use also. If there had only been some break in the eternal snow, some passing light or goal to be seen ahead, it would not have been so bad. Finally, every now and then, Ross had to jiggle off course just enough so that the warning blink of light would alert him and keep him from falling asleep. He was unaware that Kurt had awakened during one of those maneuvers until the other spoke. "Your own private alarm clock, Murdock? Okay, I do not quarrel with anyone who uses his head. But you had better get some shut-eye, or we will not keep rolling." Ross was too tired to protest. They changed places, and he curled up as best he could on his small share of seat. Only now that he was free to sleep, he realized he no longer wanted to. Kurt must have thought Ross had fallen asleep, for after perhaps two miles of steady grinding along, he moved cautiously behind the wheel. Ross saw by the trace of light from the instrument panel that his companion was digging into the breast of his parka to bring out a small object which he held against the wheel of the cat with one hand, while with the other he tapped out an irregular rhythm. To Ross the action made no sense. But he did not miss the other's sigh of relief as he restored his treasure to hiding once more, as if some difficult task was now behind him. Shortly afterward the cat ground to a stop, and Ross sat up, rubbing his eyes. "What's the matter? Engine trouble?" Kurt had folded his arms across the wheel. "No. It is just that we are to wait here----" "Wait? For what? Kelgarries to come along and pick us up?" Kurt laughed. "The major? How I wish that he _would_ arrive presently. What a surprise he would receive! Not two little mice to be put back into their cages, but the tiger cat, all claws and fangs!" Ross sat up straighter. This now had the bad smell of a frame, a frame with himself planted right in the middle. He figured out the possibilities and came up with an answer which would smear Ross Murdock all over any map. If Kurt were waiting to meet friends out here, they could only be of one brand.
