Tide Ledger of Borrowed Rooms

Salinity: 28.4 PSU — anemone foot clasp spans 3.1 cm against an oyster roof.

Shells catalogued: 14 occupied, 5 vacant; one crab rehearses a hinge at 0.2 mm per hour.

Estuary bank: sediment deposits layered like index cards; polychaetes refile the margins.

Instrument notes: no interpretation offered — devices tape the repairs with salt and thread.
