1. In this mandamus proceeding against Wheat Williams, as sole Commissioner of Roads and Revenues of DeKalb County, to require him to record on his minutes two contracts which purport to lease certain county property to the plaintiff for a fixed period of time and for a specified amount as annual rent, and where the alleged contracts were in proper form and prima facie valid, no further inquiry as to their validity can be made in the mandamus proceeding; but all other questions respecting their validity must be determined in another action unaffected by the judgment in this case.

2. When, as in this case, a sole commissioner of roads and revenues makes a contract for and on behalf of the county, it is his duty to record it on his minutes promptly, and when he fails to do so, mandamus will lie to1 compel him or his successor in office to perform such official duty, unless the applicant for such relief has with respect thereto been guilty of gross laches or has permitted an unreasonable period of time to elapse before applying to the proper court therefor.

4. While, under Code § 64-106, mandamus will not be granted when it is manifest that the writ would, for any cause, be nugatory or fruitless, and while this court will and does take judicial notice of the fact that the defendant Williams is not now the Commissioner of Roads and Revenues of DeKalb County, the judgment excepted to will, for the reasons stated above, be reversed in order that the applicant for the writ may not be estopped thereby.
