Looking up at the clouds, I tried to have an Idea of them, but the only Idea that occurred to me was of the clouds of the previous day — “upside down mossbed” — which I hadn’t thought to call them then. All cirrus clouds in blue skies evoke plains, beaches, deserts above, I then thought. (Though not necessarily “upside down” because “you seem to see them from within an airplane.”)
Had read Apollinaire the previous night. Description of the flares overhead, which I recall because I am looking overhead, but I can’t recall the French word for “flares” presently. I can’t even recall the French word for “above.”
