Getting Gold. A practical treatise for prospectors, miners and students ... With illustrations
A practical handbook on gold prospecting and small-scale mining written by J. C. F. Johnson and published by Charles Griffin in London in 1897 for working prospectors, miners and students. The plates are numbered line diagrams: side elevations of sluices, cradles and rocker frames drawn in plain outline, plus geological cross-sections where slate and sandstone beds are distinguished by hatching and labelled in capitals, useful as simple technical schematics and hatch-texture samples.
