The Secretary of the Interior or such officer as he may designate shall engage a sufficient number of skillful surveyors as his deputies, to whom he is authorized to administer the necessary oaths upon their appointments. He shall have authority to frame regulations for their direction, not inconsistent with law or the instructions of the Bureau of Land Management, and to remove them for negligence or misconduct in office.
Second. He shall cause to be surveyed, measured, and marked, without delay, all base and meridian lines through such points and perpetuated by such monuments, and such other correction parallels and meridians as may be prescribed by law or by instructions from the Bureau of Land Management, in respect to the public lands to which the Indian title has been or may be extinguished.
Fourth. He shall transmit to the officer, as the Secretary of the Interior may designate, of the respective land offices general and particular plats of all lands surveyed by him for each land district; and he shall forward copies of such plats to such officer as the Secretary may designate.
Fifth. He shall, so far as is compatible with the desk duties of his office, occasionally inspect the surveying operations while in progress in the field, sufficiently to satisfy himself of the fidelity of the execution of the work according to contract, and the actual and necessary expenses incurred by him while so engaged shall be allowed; and where it is incompatible with his other duties for the Secretary of the Interior or such officer as he may designate to devote the time necessary to make a personal inspection of the work in progress, then he is authorized to depute a confidential agent to make such examination; and the actual and necessary expenses of such person shall be allowed and paid for that service, and $5 a day during the examination in the field; but such examination shall not be protracted beyond thirty days; and in no case longer than is actually necessary; and when the Secretary or such officer, or any person employed in his office at a regular salary, is engaged in such special service, he shall receive only his necessary expenses in addition to his regular salary.
