“This is the law of the Yukon , that only the strong shall thrive; that surely the weak shall perish, and only the fit survive.”

“I love not man the less, but Nature more”

“Spring is nature's way of saying, 'Let's party!”

“I wandered lonely as a cloud.”

“The more clearly we can focus our attention on the wonders and realities of the universe about us, the less taste we shall have for destruction.”
