Rapport sur les mines de houille de l'Angleterre ...
A French mining report on English coal mines, written by Théophile Guibal with A. Boty and G. Glépin and published by Emm. Hoyois in 1844, presented to French engineers and mine administrators as a survey of British collieries. The pictures include a plan of underground workings with dense hatched galleries, a drawn winding or pumping machine with a large drum, a colliery engraving with headgear and a tall chimney beside a rail track, and a regional geological map of northern England with coloured strata and town names, giving a designer clear diagrams of industrial layout and sober cartographic colour.
