At the table

The company is bound into the green-coal chain. Its London rooms negotiate charters, subscriptions and insurance; its Sarrum chapter decides how those decisions are to be made to work below ground. Provincial Director Walter Hume is named in connection with these Sarrum boards. Ordinary matters of the ground pass through Kersey's contracts desk, and the Black Caps guard its green-coal stores. What salvage it takes it will not say, and no one in the March knows what becomes of the metal: of all the district's trade, this is the one part kept secret from the district itself.
