Plotting equipment

Plotting equipment

Geologists were expected to plot up their observations at night or on wet days. Max Gage took this photograph of equipment he used: notebook, protractor sheet on tracing paper, parallel ruler, slide rule for calculations, scale and 4H pencil. After a traverse was plotted and adjusted on tracing paper, it was pricked through on to the Whatman’s field sheet, and geological features were marked in coloured inks.
