VII of the Illinois Coal Mining Investigations, as shown in fig. 1, includes all mines operating in coal bed 6 west of the Duquoin anticline and north as far as an east-west line about 6 miles south of Springfield.

Fayette county at present does not contribute to the production of the district. Table 1 gives general data for district VII by counties. A detailed description of the districts into which the State has been divided and the method of collecting the data upon which this bulletin is based is contained in Bulletin 1, A I're liminary Report on Organization and Method. The coal output of the district for the year ended June 30, 1912, was short tons, per cent of the total production of the State. This output came from 196 mines, 150 shipping and 46 local, employing men and operating on an average of 158 days in the year. The number of employees was per cent of all employed in coal mining in the State. The use of undercutting machines made possible the production of per cent of the State's coal output by per cent of the employees.

During the year ended June 30. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
