“ It is in this effect of the patent as a record of the government that its security and protection chiefly lie. If parties asserting interests in lands acquired since the acquisition of the country could deny and controvert this record, and compel the patentee, in every suit for his land, to establish the validity of his claim, his right to its confirmation, and the correctness of the action of the tribunals and officers of the United States in the location of the same, the patent would fail to be, as it was intended it should be, an instrument of quiet and security to its possessor. ”

“ The intruder, resting solely upon his possession, might insist that the original claim was invalid, or was not properly located, and, therefore, he could not be disturbed by the patentee. No construction which will lead to such results can be given to the fifteenth section. The term 'third persons,' as there used, does not embrace all persons other than the United States and the claimants, but only those who hold superior titles, such as will enable them to resist successfully any action of the government in disposing of the property. ”

“ They show 'a claim by virtue of a right or title derived from the Spanish or Mexican government,' which is all that is required by the act of 1851. That act does not define the character of the right or title, or prescribe the kind of evidence by which it shall be established. It is sufficient that the right or title is derived from the Spanish or Mexican government, and it may in some instances rest in the general law of the land, as is the case usually with the title of municipal bodies, under the Spanish and Mexican systems, to their common lands. ”
