The operator or superintendent of every mine shall furnish the

mine inspectors of the district in which said mine is located with a

correct copy, on tracing muslin or sunprint, of the map or plan of

said mine hereinbefore provided for, and the inspector of the

district shall at the end of each year, or twice a year, if he

requires it, return said map or plan to the proper person at any

particular mine, whose duty it shall be to place or cause to be

placed, on said map or plan all extensions and worked out or

abandoned parts of the mine during the preceding six (6) or twelve

(12) months, as the case may be, and forward the same to the

district mine inspector within thirty (30) days from the time of

receiving it. When any mine is worked out or abandoned, the

operator or superintendent shall furnish the mine inspector, within

thirty (30) days, with a correct plan of said mine on tracing muslin

or cloth, which plan shall clearly show all the worked out or

abandoned territory, together with all property and boundary lines,

elevations, and other things required by this article. The copies

of the maps or plans of the several coal and other mines in each

district, as hereinbefore required to be furnished to the mine

inspector, shall remain in the care of the inspector of the district

in which the said mines are situated, as strictly official records,

to be transferred by him to his successor in office.
