"The superintendent of mines should possess knowledge of the science dealing with copper and other minerals; he should have experience in the art of distillation and condensation of mercury and of testing gems. Aided by experts in mineralogy and provided with mining labourers and necessary instruments he shall examine mines which, on account of their containing mineral excrement, crucibles, charcoal and ashes, may appear to have been once exploited, or which may be newly discovered on plains or mountain slopes possessing mineral ores, the richness of which can be ascertained by weight, depth of colour, piercing smell and taste."
