in Thoreau’s Journal:

Suddenly I see a broad reach of blue beneath, with its curves and headlands, liberating me from the more terrene earth. What a difference it makes whether I spend my four hours nooning between the hills by yonder roadside, or on the brink of this fair river, within a quarter of a mile of that! Here the earth is fluid to my thought, the sky is reflected from beneath, and around yonder cape is the highway to other continents. This current allies me with the world.
