“
How hard to realize that every camp of men or beast has this glorious starry firmament for a roof! … In such places standing alone on the mountain-top it is easy to realize that whatever special nests we make — leaves and moss like the marmots and birds, or tents, or piled stone — we all dwell in a house of one room — the world with the firmament for its roof — and are sailing the celestial spaces without leaving any track.
