ten dollars shall be expended annually in labor or improvements on each claim 

 of one hundred J^eet on the course of the vein or lode until a patent shall have 

 been issued therefor; but where a number of such claims are held in common 

 upon the same vein or lode, the aggregate expenditure that would be necessary 

 to hold all the claims, at the rate oi ten dollars per hundred feet, may be made 

 upon any one claim; a failure to comply with this requirement in any one year 

 subjecting the claim upon which such failure occurred to relocation by other 

 parties, the same as if no previous location thereof had ever been made, unless 

 the claimants under the original location shall have resumed work thereon after 

 such failure and before such relocation. The first annual expenditure upon 

 claims oi this class should have been performed subsequent to May lo, 1872, 

 and prior to January 1, 1875. From and after January 1, 1875, the required 

 amount must be expended annually until patent issues. By decision of the 

 honorable Secretary of the Interior, dated March 4, 1879, such annual expendi- 

 tures are not required subsequent to entry, the date of issuing the patent certifi- 

 cate being the date contemplated by statute. 



6. Upon the failure of any one of several co-owners of a vein, lode, or ledge, 

 which has not been entered, to contribute his proportion of the expenditures 

 necessary to hold the claim or claims so held in ownership in common, the co- 

 owners, who have performed the labor or made the improvements as required 

 by said Revised Statutes, may, at the expiration of the year, give such delin- 

 quent co-owner personal notice in writing, or notice by publication in the news- 

 paper published nearest the claim for at least once a week for ninety days; and 

 if upon the expiration of ninety days after such notice in writing, or upon the 

 expiration of one hundred and eighty days after the first newspaper publication 

 of notice, the delinquent co-owner shall have failed to contribute his proportion 

 to meet such expenditures or improvements, his interest in the claim by law 

 passes to his co-owners who have made the expenditures or improvements as 

 aforesaid. Where a claimant alleges ownership of a forfeited interest under the 

 foregoing provision, the sworn statement of the publisher as to the facts of pub- 

 lication, giving dates and a printed copy of the notice published, should be fur- 

 nished, and the claimant must swear that the delinquent co-owner failed to 

 contribute his proper proportion within the period fixed by the statute. 



PATENTS FOR VEINS OR LODES HERETOFORE ISSUED. 



7. Rights under patents for veins or lodes heretofore granted under previous 

 legislation of Congress are enlarged by the Revised Statutes so as to invest the 

 patentee, his heirs or assigns, with title to all veins, lodes, or ledges throughout 

 their entire depth, the top or apex of which lies within the end and side bound- 

 ary lines of his claim on the surface, as patented, extended downward vertically^
