Riassunto

Excerpt from The Practical Miner's Guide: A Treatise on Mine Engineering; Comprising a Set of Trigonometrical Tables, Adapted to All Purpose of Oblique or Diagonal, Vertical, Horizontal, and Traverse Dialling, With Their Application to the Dial Exercise of Shafts, Adits, Drifts, Lodes, Slides

IT is an acknowledged fact, that dialling, in all its varieties, is the most difficult and momentous part of the duty of practical mine agents. To assist them in that important operation, is the chief de sign in giving publicity to these Tables.

Notwithstanding the great improvements which of late years have been made in the art of dialling, the most intelligent miners universally admit, that the practice is still very imperfect; nay, so far are they from any determinate and general system, that two persons can scarcely be found who precisely adopt the same method; consequently, some plain scheme, founded on pure mathematical principles, is a great mining desideratum.
