The Witwatersrand Goldfields Banket and Mining Practice
A technical manual on the Witwatersrand banket deposits and their working, written by Samuel John Truscott and published by Macmillan in London in 1898 for mining engineers and surveyors. The plates are hard-line engineered diagrams — paired plans and sections of shafts, ore bins and loading stations, reef profiles with hatched rock bands, dip and fault angles marked in degrees — offering designers scale bars, small-capital labels with leader lines, and flat geometric underground layouts.
