There may be selected by the road commissioners, subject to the confirmation of the board of supervisors, a competent road superintendent, whose compensation shall be fixed by the board of supervisors, who shall hold his office for one year unless sooner removed, and who shall give a good and sufficient bond for the faithful performance of his duties. Such superintendent shall work under the direction of the road commissioners and may require any or all directions given him by the commissioners to be in writing. He shall give his whole time to the working of the roads in the district except when the commissioners, on account of weather or other conditions, may direct him otherwise. All labor employed on the roads in the district shall be employed by the superintendent and shall be under his control and direction, but the wages paid or agreed to be paid such labor shall be subject to revision and correction by the road commissioners. The superintendent shall file each month with the road commissioners a payroll showing the name of each laborer, the number of days each worked, and the amount due him. When this payroll shall have been approved by the commissioners and transmitted to the board of supervisors and approved by them, warrants on the road fund of the district shall be issued in accordance therewith.
