1. Story
2. The material on which the whole transition turns, and the reason it happened where it did. Britain had worked coal since the Middle Ages — the Tyne shipped sea-coal to London for domestic hearths long before any engine existed — but coal was a heating fuel with two hard limits: its sulphur spoiled iron smelted with it, and the deeper seams flooded faster than horse gins could lift the water. Both limits fell in the eighteenth century, coke smelting removing the first and the pumping engine the second, and once they did, coal stopped being a fuel among others and became the substrate of a different kind of economy. Its decisive property is not that it burns but that it is a stock rather than a flow: a ton of coal represents solar energy accumulated over geological time, so consuming it takes nothing from this year's harvest. British output rose by something like an order of magnitude across the eighteenth century and by roughly another across the nineteenth. The geography of the coalfields — the north-east, south Wales, the Midlands, Lancashire, Yorkshire, central Scotland — is very nearly the geography of nineteenth-century industrial Britain.

20. Named as the canonical source for the output and trade series referred to qualitatively in this pack. V55 verification basis: NOT consulted. No numeric series from Mitchell is quoted here for that reason; every output statement in this pack is deliberately an order of magnitude rather than a figure, and a curator with access should replace those statements with dated numbers.
21. Supports the organic-economy framing: that a photosynthesis-based economy faces a land-area ceiling on all energy and material uses simultaneously, and that coal is an escape from it because it draws on a stock rather than a flow. V55 verification basis: NOT consulted in this session; the acreage-equivalent figures Wrigley gives are therefore deliberately not quoted anywhere in this pack.
