A long wall follows the fence. A wall without opening, without doors, without windows, a well which stops 200 yards further on, against a house. I have passed out of range of the lamp-post; I enter the black hole. Seeing the shadow at my feet lose itself in the darkness, I have the impression of plunging into icy water. Before me, at the very end, through the layers of black, I can make out a pinkish pallor: it is the Avenue Galvani. I turn back; behind the gaslamp, very far, there is a hint of light: that is the station with the four cafes. Behind me, in front of me, are people drinking and playing cards in pubs. Here there is nothing but blackness. Intermittently, the wind carries a solitary, faraway ringing to my ears. Familiar sounds, the rumble of motor cars, shouts, and the barking of dogs which hardly venture from the lighted streets, they stay within the warmth. But the ringing pierces the shadows and comes thus far: it is harder, less human than the other noises.
I stop to listen. I am cold, my ears hurt; they must be all red. But I no longer feel myself; I am won over by the purity surrounding me; nothing is alive, the wind whistles, the straight lines flee into the night. The Boulevard Noir does not have the indecent look of bourgeois streets, offering their regrets to the passers-by. No one has bothered to adorn it: it is simply the reverse-side. [...] The Boulevard Noir is inhuman. Like a mineral. Like a triangle.
