Excerpt from Principles of Metal Mining

The art of mining must, to a large extent, be learnt at the mine, either underground or at the surface. The diligent student, however, will obtain much aid from external sources, and it is the object of this little work to convey some elementary knowledge of the principles and facts of mining in a form suitable for the instruction of young miners starting in life - to teach them what to observe - and how to interpret their observations.

The young student should endeavour to add to his own limited experience the larger experiences of many men in many countries - by reading as well as by conversation with his travelled comrades. He should also accustom himself to make written notes of the peculiarities of all mineral deposits with which he may become acquainted, and of the cost and comparative efficiency of all tools, machinery, and materials which may come under his notice.
