A Treatise on Mine-surveying ... With ... diagrams
A technical textbook on mine-surveying written by Bennett Hooper Brough and published by Charles Griffin & Co. in London in 1894 for mining students, engineers and practising surveyors. The plates are fine-line engraved diagrams: instrument rods and plumb lines in oblique projection, dashed construction lines with lettered points, angle arcs, and ruled scale grids that yield clean geometric line art and numbered measuring rules.
