The Staircase
STEPPER persist 13 · act 13 · react 91 · learn 13 · loop 1
LIT STEPPER keeps a rise only when the offer is that rise and not the next one. Thirteen rises, and the offers sum to 91, which is the thirteenth triangular number. The dropped offer on each tread is one higher, and it is not cut into the wood.
AMBER This is the page's stair. It is not a count taken in a building. The novel's publication is the assigned 1866 in The Russian Messenger, twelve parts, and a book in 1867. The cul-de-sac is the suburban loop of the same climb.
WALL The flight stops at thirteen. The bulb is a stage mark.
MODEL A side elevation. The tread is the kept number. The darker block is the riser.
Checking the yard.
