parts of such veins or ledges. And nothing in this section shall au- 

 thorize the locator or possessor of a vein or lode which extends in its 

 downward course beyond the vertical lines of his claim to enter upon 

 the surface of a claim owned or possessed by another. 



Owners of tunnel sites. 



Sec. 2323. Where a tunnel is run for the development of a vein or 

 lode, or for the discovery of mines, the owners of such tunnel shall 

 have the right of possession of all veins or lodes within three thousand 

 feet from the face of such tunnel on the line thereof, not previously 

 known to exist, discovered in such tunnel, to the same extent as if 

 discovered from the surface ; and locations on the line of such tunnel 

 of veins or lodes not appearing on the surface, made by other parties 

 after the commencement of the tunnel, and while the same is being 

 prosecuted with reasonable diligence, shall be invalid, but failure 

 to prosecute the work on the tunnel for six months shall be con- 

 sidered as an abandonment of the right to all undiscovered veins 

 on the line of such tunnel. 



Regulations of miners; assessment work, etc. 



Sec. 2324. The miners of each mining district may make regula- 

 tions not in conflict with the laws of the United States, or with the 

 laws of the State or Territory in which the district is situated, gov- 

 erning the location, manner of recording, amount of work necessary 

 to hold possession of a mining claim, subject to the following require- 

 ments: The location must be distinctly marked on the ground so 

 that its boundaries can be readily traced. All records of mining 

 claims hereafter made shall contain the name or names of the lo- 

 cators, the date of the location, and such a description of the claim 

 or claims located by reference to some natural object or permanent 

 monument as will identify the claim. On each claim located after 

 the tenth day of May, eighteen hundred and seventy-two, and until 

 a patent has been issued therefor, not less than one hundred dollars' 

 worth of labor shall be performed or improvements made during 

 each year. On all claims located prior to the tenth day of May, 

 eighteen hundred and seventy-two, ten dollars' worth of labor shall 

 be performed or improvements made by the tenth day of June, 

 eighteen hundred and seventy-four, and each year thereafter, for 

 each one hundred feet in length along the vein until a patent has been 

 issued therefor; but where such claims are held in common, such ex- 

 penditure may be made upon any one claim; and upon a failure to 

 comply with these conditions the claim or mine upon which such 

 failure occurred shall be open to relocation in the same manner as if 

 no location of the same had ever been made, provided that the orig- 

 inal locators, their heirs, assigns, or legal representatives, have not 

 resumed work upon the claim after failure and before such location. 

 Upon the failure of any one of several co-owners to contribute his 

 proportion of the expenditures required hereby, the co-owners who 

 have performed the labor or made the improvements may, at the ex- 

 piration of the year, give such delinquent co-owner personal notice 

 in writing or notice by publication in the newspaper published near-

 expiration of ninety days after such notice in writing or by publica-
