“I used to sit in class and listen to the terms come floating down the room like paper airplanes.”

“The doctor listens in with a stethoscope and hears sounds of a warpath Indian drum. ”

“Speaking of libraries: A big open-stack academic or public library is no small pleasure to work in. You're, say, trying to do a piece on something in Nevada, and you go down to C Floor, deep in the earth, and out to what a miner would call a remote working face. You find 10995.497S just where the card catalog and the online computer thought it would be, but that is only the initial nick. The book you knew about has led you to others you did not know about. To the ceiling the shelves are loaded with books about Nevada. You pull them down, one at a time, and sit on the floor and look them over until you are sitting on a pile five feet high, at which point you are late home for dinner and you get up and walk away. It's an incomparable boon to research, all that; but it is also a reason why there are almost no large open-stack libraries left in the world.”

“A quarter-horse jockey learns to think of a twenty-second race as if it were occurring across twenty minutes--in distinct parts, spaced in his consciousness. Each nuance of the ride comes to him as he builds his race. If you can do the opposite with deep time, living in it and thinking in it until the large numbers settle into place, you can sense how swiftly the initial earth packed itself together, how swiftly continents have assembled and come apart, how far and rapidly continents travel, how quickly mountains rise and how quickly they disintegrate and disappear.”

“If you free yourself from the conventional reaction to a quantity like a million years, you free yourself a bit from the boundaries of human time. And then in a way you do not live at all, but in another way you live forever.”

“Now, at Suiattle Pass, Brower was still talking about butterflies. He said he had raised them from time to time and had often watched them emerge from the chrysalis--first a crack in the case, then a feeler, and in an hour a butterfly. He said he had felt that he wanted to help, to speed them through the long and awkward procedure; and he had once tried. The butterflies came out with extended abdomens, and their wings were balled together like miniature clenched fists. Nothing happened. They sat there until they died. 'I have never gotten over that,' he said. 'That kind of information is all over in the country, but it's not in town.”

“If by some fiat I had to restrict all this writing to one sentence, this is the one I would choose: The summit of Mt. Everest is marine limestone. ”
