A mining handbook by John Budge, published by G. M. Newton in 1858, giving trigonometrical tables for underground dialling and surveying plus instructions on assaying silver, copper, lead and tin, written for working miners and mine agents. The plates are bare line diagrams: right-angled triangles, dotted lode lines and lettered vertices, useful as spare geometric marks, surveying motifs and diagram scaffolding.
