Försök til handledning uti svenska markscheideriet
A Swedish mining-surveying manual published in Stockholm in 1802 by L. Horneman, written as an introduction to surveying practice for mine work. Its plates are numbered engraved figures of instruments and mine workings, and the two shown are technical diagrams of surveying tools and of furnace and shaft layouts. A designer could take from them the precise, labelled line-drawing style of early technical plates, with figure numbers and grid-like scale bars.
