“One day's exposure to mountains is better than a cartload of books.”

“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.”

“It was the afternoon of the day and the afternoon of his life, and his course was now westward down all the mountains into the sunset. [speaking about Ralph Waldo Emerson]”

“I am losing precious days. I am degenerating into a machine for making money. I am learning nothing in this trivial world of men. I must break away and get out into the mountains to learn the news”

“Going to the mountains is going home.”

“The mountains are calling and I must go.”

“Few places in this world are more dangerous than home. Fear not, therefore, to try the mountain passes. They will kill care, save you from deadly apathy, set you free, and call forth every faculty into vigorous, enthusiastic action.”
