His second problem was sleep. He could not stay awake all the time, and yet that was really what the situation required. Here, too, he was forced to make certain concessions. As with eating, Quinn felt that he could make do with less than he was accustomed to. Instead of the six to eight hours of sleep he was used to getting, he decided to limit himself to three or four. Adjusting to this was difficult, but far more difficult was the problem of how to distribute these hours so as to maintain maximum vigilance. Clearly, he could not sleep for three or four hours in a row. The risks were simply too great. Theoretically, the most efficient use of the time would be to sleep for thirty seconds every five or six minutes. That would reduce his chances of missing something almost to nil. But he realized that this was physically impossible. On the other hand, using this impossibility as a kind of model, he tried to train himself into taking a series of short naps, alternating between sleeping and waking as often as he could. It was a long struggle, demanding discipline and concentration, for the longer the experiment went on, the more exhausted he became. In the beginning, he tried for sequences of forty-five minutes each, then gradually reduced them to thirty minutes. Towards the end, he had begun to manage the fifteen-minute nap, with a fair amount of success. He was helped in his efforts by a nearby church, whose bells rang every fifteen minutes-one stroke on the quarter-hour, two strokes on the half-hour, three strokes on the three-quarter-hour, and four strokes on the hour, followed by the appropriate number of strokes for the hour itself Quinn lived by the rhythm of that clock, and eventually he had trouble distinguishing it from his own pulse. Starting at midnight, he would begin his routine, closing his eyes and failing asleep before the clock had struck twelve. Fifteen minutes later he would wake,, at the half-hour double stroke fall asleep, and at the three-quarter-hour triple stroke wake once more. At three-thirty he would go off for his food, return by four o'clock, and then go to sleep again. His dreams during this period were few. When they did occur, they were strange: brief visions of the immediate-his hands, his shoes, the brick wall beside him. Nor was there ever a moment when he was not dead tired.
His third problem was shelter, but this was more easily solved than the other two. Fortunately, the weather remained warm, and as late spring moved into summer, there was little rain. Every now and then there was a shower, and once or twice a downpour with thunder and lightning, but all in all it was not bad, and Quinn never stopped giving thanks for his luck. At the back of the alley there was a large metal bin for garbage, and whenever it rained at night Quinn would climb into it for protection. Inside, the smell was overpowering, and it would permeate his clothes for days on end, but Quinn preferred it to getting wet, for he did not want to run the risk of catching cold or falling ill. Happily, the lid had been bent out of shape and did not fit tightly over the bin. In one comer there was a gap of six or eight inches that formed a kind of air hole for Quinn to breathe through-sticking his nose out into the night. By standing on his knees on top of the garbage and leaning his body against one wall of the bin, he found that he was not altogether uncomfortable.
On clear nights he would sleep under the bin, positioning his head in such a way that the moment he opened his eyes he could see the front door of the Stillmans' building. As for emptying his bladder, he usually did this in the far comer of the alley, behind the bin and with his back to the street. His bowels were another matter, and for this he would climb into the bin to ensure privacy. There were also a number of plastic garbage cans beside the bin, and from one of these Quinn was usually able to find a sufficiently clean newspaper to wipe himself, although once, in an emergency, he was forced to use a page from the red notebook. As for washing and shaving, these were two of the things that Quinn learned to live without.
How he managed to keep himself hidden during this period is a mystery. But it seems that no one discovered him or called his presence to the attention of the authorities. No doubt he learned early on the schedule of the garbage collectors and made sure to be out of the alley when they came. Likewise the building superintendent, who deposited the trash each evening in the bin and the cans. Remarkable as it seems, no one ever noticed Quinn. It was as though he had melted into the walls of the city.
The problems of housekeeping and material life occupied a certain portion of each day. For the most part, however, Quinn had time on his hands. Because he did not want anyone to see him, he had to avoid other people as systematically as he could. He could not look at them, he could not talk to them, he could not think about them. Quinn had always thought of himself as a man who liked to be alone. For the past five years, in fact, he had actively sought it. But it was only now, as his life continued in the alley, that he began to understand the true nature of solitude. He had nothing to fall back on anymore but himself. And of all the things he discovered during the days he was there, this was the one he did not doubt: that he was falling. What he did not understand, however, was this: in that he was falling, how could he be expected to catch himself as well? Was it possible to be at the top and the bottom at the same time? It did not seem to make sense.
He spent many hours looking up at the sky. From his position at the back of the alley, wedged in between the bin and the wall, there were few other things to see, and as the days passed he began to take pleasure in the world overhead. He saw that, above all, the sky was never still. Even on cloudless days, when the blue seemed to be everywhere, there were constant little shifts, gradual disturbances as the sky thinned out and grew thick, the sudden whitenesses of planes, birds, and flying papers. Clouds complicated the picture, and Quinn spent many afternoons studying them, trying to learn their ways, seeing if he could not predict what would happen to them. He became familiar with the cirrus, the cumulus, the stratus, the nimbus, and all their various combinations, watching for each one in its turn, and seeing how the sky would change under its influence. Clouds, too, introduced the matter of color, and there was a wide range to contend with, spanning from black to white, with an infinity of grays between. These all had to be investigated, measured, and deciphered. On top of this, there were the pastels that formed whenever the sun and the clouds interacted at certain times of day. The spectrum of variables was immense, the result depending on the temperatures of the different atmosphere levels, the types of clouds present in the sky, and where the sun happened to be at that particular moment. From all this came the reds and pinks that Quinn liked so much, the purples and vermilions, the oranges and lavenders, the golds and feathery persimmons. Nothing lasted for long. The colors would soon disperse, merging with others and moving on or fading as the night appeared. Almost always there was a wind to hasten these events. From where he sat in the alley, Quinn could rarely feel it, but by watching its effect on the clouds, he could gauge its intensity and the nature of the air it carried. One by one, all weathers passed over his head, from sunshine to storms, from, gloom to radiance. There were the dawns and dusks to observe, the midday transformations, the early evenings, the nights. Even in its blackness, the sky did not rest. Clouds drifted through the dark, the moon was forever in a different form, the wind continued to blow. Sometimes a star even settled into Quinn's patch of sky, and as he looked up he would wonder if it was still there, or if it had not burned out long ago.
