MINE INSPECTION IN ALASKA.

The provisions of the act for the protection of the lives of miners in the Territories (approved Mar. 3, 1891, 26 Stat., 1104, and amended July 1, 1902, 32 Stat., 631) were extended to Alaska in connection with the appropriations for the work of the Bureau of Mines, under the following clauses of the sundry civil acts of 1911 and 1912:

For salaries of two mine inspectors authorized by the act approved March third, eighteen hundred and ninety-one, for the protection of the lives of miners in the Territories, at two thousand dollars per annum each, four thousand dollars; and said inspectors are hereby authorized to inspect coal and other mines in the District of Alaska, to which district the provisions of said act are hereby extended and made applicable.

For salaries of two mine inspectors, authorized by the act approved March third, eighteen hundred and ninety-one, for the protection of the lives of miners in the Territories, five thousand dollars; and said inspectors are hereby authorized to inspect coal and other mines in the District of Alaska, to which District the provisions of said act, except so much as requires six months' residence in a Territory prior to appointment, are hereby extended and made applicable.
