The examination will be held in the office of the State Director who made the request, but it is not limited to residents of that State and anyone whose application has been accepted may take the examination at his own expense. Upon successful completion of the examination, the applicant will furnish the names of three references who are familiar with his character, integrity and capability as a surveyor. The examination is prepared by the Washington Office and mailed in a sealed envelope bearing the applicant’s name to the State office. The completed examination is returned to the Washington Office in a sealed envelope for each applicant for grading. Duties of the Mineral Surveyor =3–10= The duties of the mineral surveyor begin with an order for survey and cease with the approval of that survey. This precludes using data acquired by former surveys and by reason of having made the location or amended location survey, unless such data is verified by field work and examination after the survey order is issued. The surveyor should not act as agent for the claimant in the signing of location or amended location certificates, although he may post such notices for the claimant. _The mineral surveyor is prohibited from taking any part in the patent application;_ however, he may assist the attorney or agent or the claimant himself in interpreting his field notes, including the area statement. A mineral surveyor exceeds his duties if he prepares the notices of application for patent (24 L.D. 193). =3–11= The survey must be made in person by the mineral surveyor. This does not mean that every physical act of survey must be performed by him, but it must be performed under his direct supervision in the field. The mineral surveyor is prohibited from delegating such supervision to employees. In other words, the mineral surveyor cannot send a field party out to do the work under his authority without being on the ground himself. There is no objection to having more than one survey crew perform the field work as long as the mineral surveyor can give each crew adequate supervision. The same rule applies to office work in connection with the survey. There is nothing that prohibits a mineral surveyor from being a part of an engineering and/or surveying firm, but he should be a principal of that firm. If he works as an employee of such a firm, he is compromising his appointment, for as a mineral surveyor he is an employee of the Bureau of Land Management. He cannot be an employee of the claimant, nor can he employ the claimant, his attorney or parties in interest as assistants in making surveys of mineral claims (43 C.F.R. 3861.3–2). =3–12= The survey must be an actual survey on the ground. This precludes the calculation of ties and other lines through prior surveys. (See 6 L.D. 718 which disallowed a section corner tie calculated from another survey and required an amended survey to run the section tie on the ground.)
