The disordered condition of Arizona consequent on the Civil War and the continued hostilities of the Apaches, so impeded mining enterprises, compelling the abandonment of valuable mines and preventing full compliance with the conditions of the preceding acts, from no lack of diligence or skill on the part of miners, that some legislation seemed to be necessary to protect them from the injustice which a strict enforcement of the law would necessitate. The following acts were accordingly passed and approved on the dates specified. An act approved March 1st, 1873, amends Section 5 of the Act of 1872, above referred to, so as to read as follows: “That the time for the annual expenditure on claims located prior to the passage of said act, shall be extended to the 10th day of June, 1874.” An act approved June 6th, 1874, made a further extension to January 1st, 1875. An act approved February 11th 1875, so amends Section 2324, Revised Statutes, as to provide that where “a person or company has or may run a tunnel for the purpose of developing a lode or lodes owned by said person or company, the money so expended on said tunnel shall be taken and considered as expended on said lode or lodes, whether located prior to or since the passage of said act; and such person or company shall not be required to perform work on the surface of said lode or lodes in order to hold the same, as required by said act.” Recording Location. Within a reasonable time, after the location shall have been marked on the ground, notice thereof, accurately describing the claim in manner aforesaid, should be filed for record with the proper recorder of the district, who will thereupon issue the usual certificate of location. The district regulations or customs are followed in this regard. Within ninety days after location, a location certificate must be filed in the office of the Recorder, in the county in which the lode is situated, which should be in the following form: TERRITORY OF ARIZONA, } ss.
