“The world, we are told, was made especially for man — a presumption not supported by all the facts.”

“One learns that the world, though made, is yet being made; that this is still the morning of creation; that mountains long conceived are now being born, channels traced for coming rivers, basins hollowed for lakes...”

“C. albus...I think the very loveliest of all the lily family,- a spotless soul, plant saint, that every one must love and so be made better. It puts the wildest mountaineer on his good behavior. With this plant the whole world would seem rich though non other existed.”

“When we tug at a single thing in nature, we find it attached to the rest of the world.”

“All the world was before me and every day was a holiday, so it did not seem important to which one of the world's wildernesses I first should wander.”

“Who wouldn't be a mountaineer! Up here all the world's prizes seem nothing”

“We all travel the Milky Way together, trees and men.”
