"As an introduction to this thesis, it would probably be well to give the laws of the State of Illinois relative to mine maps. These laws come under "An Act to revise the laws in relation to the coal mines and subjects relating thereto, and providing for the health and safety of persons employed therein. Approved June 6, 1911, inforce July 1, 1911. leaf 1911, page 388." Section 7 reads as follows: (a) The operator of every coal mine in the State shall make, or cause to be made, an accurate map or plan of such mine, drawn to a scale not smaller than 200 feet to the inch"--Introduction, page 1.
