A long time ago, when humans still lived in cities, on a cold morning near the end of a long, cruel winter, in magnificent Central Park in the middle of magnificent New York City, a young squirrel named Patch was awakened very early by the growls of his empty stomach. A squirrel's home is called a drey. Patch's drey was very comfortable. He lived high up an old oak tree, in a hollowed-out stump of a big branch that had long ago been cut off by humans. The entrance was only just big enough for Patch to squeeze in and out, but the drey itself was spacious, for a squirrel. Patch had lined his drey with dry leaves, grasses and bits of newspaper. It was warm and dry, and on that cold morning he would have liked nothing better than to stay home all day and sleep. But he was so hungry. Hunger filled him like water fills a glass. The cherry and maple trees had not yet started to bud; flowers had not yet begun to grow; the juicy grubs and bugs of spring had not yet emerged; and it had been two days since Patch had found a nut. Imagine how hungry you would feel if you went two whole days without eating, and you may have some idea how Patch felt that morning. Patch poked his head out of the drey into the cold air and shivered as he looked around. Clumps of white, crumbly ice still clung to the ground. Gusts of cold wind shook and rustled the trees' bare branches. The pale and distant sun seemed drained of heat. Patch took a moment to satisfy himself that there were no dangers nearby, no hawk circling above or unleashed dog below. Then he emerged from his drey and began to look for acorns. But what marvels, what miracles, what mysteries are hidden inside those simple words!
