A Treatise on Mine-surveying ... With ... diagrams
A technical textbook on mine-surveying by Bennett Hooper Brough, issued by Charles Griffin & Co. in 1896 for mining students, engineers and colliery surveyors. The 79 figures are fine line diagrams: graduated rules, dials and protractors drawn in engraved hatching, crossed sight-lines with lettered points, dashed construction lines and ruled coordinate grids, offering ready-made geometric notation, scale markings and instrument outlines.
