there was only the rushing dark ... and then the mouth of a cyclopean tunnel ... smells of age and decay ... cobwebs brushing at his face like rotted skeins of silk in a haunted house ... moldering tiles blurring by ... intersections , all dark now , the moon-balloons all gone , and it was screaming , screaming : clet me go let me go i 'll leave never come back let me go it hurts it hurts it hurrrrrrrrrr `` thrusts his fists ! ''
