3. The above diagram shows the traverse of the boundaries of a mining claim. Compute and tabulate the co-ordinates of the stations (on the form provided), treating station (I) as zero or origin. The total distances on the meridian and perpendicular of all the other stations are to be given also with reference to station (I), so as to show the error of the traverse. Tho distances are given in links. 4. Describe the methods of transferring the true bearing from the surface to the underground workings of a mine when there is one shaft, and when there are two shafts, giving diagrams.

Discuss the question of increase of temperature with depth, and its cause or causes. State how this factor affects the problem of mining at great depths. 10. State what you know about the gases that may invade the workings of metalliferous mines from the enclosing rocks. In particular, state what is the origin or mode of formation of such gases. 11. Give a rule for the recovery of a lode lost by faulting. State clearly the condition necessary for this rule to apply. 12. Describe, with diagrams the various types of faults known to you
