HALL, Com'r of Labor, Jefferson City, Mo.: SIR-I have the honor here with to submit to you the fifth annual report of this Department, for the year ending June 30, 1891. In presenting this report, it affords me much pleasure to be able to state that we have passed another year in comparative peace between miners and mine operators, only a few local strikes having occurred, and those adjusted without violence. Considering the mildness of the winter, the coal trade during the past year has been remarkably good, this report showing an increased production of 83 per cent over the previous year. The lead and zinc industry has been exceedingly active-the output having surpassed any previous year in the State's history, while the iron product shows a decrease as compared with the report of 1890. The report affords special information as to the general character and location of each mine, method of mining, production and mineral output, statistical tables showing number of employes, record of accidents, opening of new mines and closing of exhausted mines, and such other information as will, I hope, be of interest to the mining industry of the State. Very respectfully, C. C. WOODSON, State Mine Inspector. |
