G. K. Chesterton,
Alarms and Discursions
“ The old naval phrase, that the seas are England's bulwarks, is not a frigid and artificial metaphor; it came into the head of some genuine sea-dog, when he was genuinely looking at the sea. For the edge of the sea is like the edge of a sword; it is sharp, military, and decisive; it really looks like a bolt or bar, and not like a mere expansion. It hangs in heaven, grey, or green, or blue, changing in colour, but changeless in form, behind all the slippery contours of the land and all the savage softness of the forests, like the scales of God held even. ”
