“We fly, but we have not 'conquered' the air. Nature presides in all her dignity, permitting us the study and the use of such of her forces as we may understand. It is when we presume to intimacy, having been granted only tolerance, that the harsh stick fall across our impudent knuckles and we rub the pain, staring upward, startled by our ignorance.”

“It was ... disconcerting to examine your charts before a proposed flight only to find that in many cases the bulk of the terrain over which you had to fly was bluntly marked: 'UNSURVEYED.'It was as if the mapmakers had said, 'We are aware that between this spot and that one, there are several hundred thousands of acres, but until you make a forced landing there, we won't know whether it is mud, desert, or jungle -- and the chances are we won't know then!”

“…it was even more disconcerting to examine your charts before a proposed flight only to find that in many cases the bulk of the terrain over which you had to fly was bluntly marked: ‘UNSURVEYED.’ It was as if the mapmakers had said, ‘We are aware that between this spot and that one, there are several hundred thousands of acres, but until you make a forced landing there, we won’t know whether it is mud, desert, or jungle – and the chances are we won’t know then!”

“Elephant, beyond the fact that their size and conformation are aesthetically more suited to the treading of this earth than our angular informity, have an average intelligence comparable to our own. Of course they are less agile and physically less adaptable than ourselves -- nature having developed their bodies in one direction and their brains in another, while human beings, on the other hand, drew from Mr. Darwin's lottery of evolution both the winning ticket and the stub to match it. This, I suppose, is why we are so wonderful and can make movies and electric razors and wireless sets -- and guns with which to shoot the elephant, the hare, clay pigeons, and each other.”

“Like night, the desert is boundless, comfortless and infinite. Like night, it intrigues the mind and leads it to futility. When you have flown halfway across a desert, you experience the desperation of a sleepless man waiting for dawn which only comes when the importance of it's coming is lost. You fly forever, weary with an invariable scene, and when you are at last released from its monotony, you remember nothing of it because there was nothing there.”

“There are all kinds of silences and each of them means a different thing. There is the silence that comes with morning in a forest, and this is different from the silence of a sleeping city. There is silence after a rainstorm, and before a rainstorm, and these are not the same. There is the silence of emptiness, the silence of fear, the silence of doubt. There is a certain silence that can emanate from a lifeless object as from a chair lately used, or from a piano with old dust upon its keys, or from anything that has answered to the need of a man, for pleasure or for work. This kind of silence can speak. Its voice may be melancholy, but it is not always so; for the chair may have been left by a laughing child or the last notes of the piano may have been raucous and gay. Whatever the mood or the circumstance, the essence of its quality may linger in the silence that follows. It is a soundless echo.”

“I suppose if there were a part of the world in which mastodon still lived, somebody would design a new gun, and men, in their eternal impudence, would hunt mastodon as they now hunt elephant. Impudence seems to be the word. At least David and Goliath were of the same species, but, to an elephant, a man can only be a midge with a deathly sting.”
