The en-gineers who made this detailed study were S. 0. Andros, 0.M. Young, J. J. Eutledge and R. Y. Williams. Based uponthis field examination and a great volume of subsequent corre-spondence with mining men in the State a detailed report ofmining practice in each district has been published. Completedetails of the organization of the staff and of the methodsof collecting data can be found in Bulletin 1, A PreliminaryReport on Organization and Method. The averages in the tables in this bulletin based upon the97 mines examined compared with similar averages for allthe mines of the State as given in the Coal Reports of theState Mining Board show that the 97 mines examined arereally typical of the mines of the State and that conclusionsbased upon the data gathered at the chosen mines apply tothe State as a whole.
