ten dollai s shall be expended annually in labor or improvements on each claim 
of one hundred feet 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 of 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 of this class should have been performed subsequent to May 10, 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, suc ^ 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.
