The Iron Filter-Beds

Every surface is furred with a pale crust where the water has left its salts behind. The space opens out into a great open hall, roughly 6 by 8 paces. You cannot see all of it from any one place; a corner keeps part of it back. A stubby arch joins it to its neighbour, barely longer than it is tall. The silt in the nearest bed has been cut into neat blocks with a spade and stacked to dry, and never carried away.

Depth 53.
