Bell-Vaulters of the Two-Rung Carillon-Well — an age when a river-city's tower-guild builds a single bell-loft whose one great climbing ladder-of-ropes does not rise to the bells overhead but folds the climb back into its own fall: the identical knotted rung she is hauling herself UP toward the swinging bronze bells above is, in the same hemp in the same instant, already lowering her DOWN toward the ringers' floor she just left, so the highest bell is the lowest board and the loft has no top and no bottom, only the seam where up-rope is down-rope, and the Bell-Vaulters have learned that the carillon-well cannot be held onto — it must be crossed in one committed swinging haul at the fold where the rung above is the rung below, one hand catching the loft-beam and that same reach catching the ringers' rail, hung mid-air between two floors of the same tower before the carillon-well decides which floor her weight will drop her onto
