delivered the opinion of the court.
On December 31, 1933, at 9 :30 P. M., a county truck driven by Charles Jones, superintendent of the county poor farm, сollided with plaintiff’s car in the city of Anaconda. Plaintiff sued Jones and Deer Lodge County jointy for dаmages for injuries resulting from the collision, and on a trial of the action secured a verdict аnd judgment against Jones; the court, how *367 ever, directed a verdict in favor of the county. Plaintiff appeals from the judgment.
The only question presented by this appeal is as to whether or not the court erred in taking the case from the jury as to the county.
The evidence is undisputed to the following effect: Jones was required to work at the poor farm but the customary eight-hour day, exсept in case of an emergency; the truck involved was furnished him for use in connection with his work, аnd for no other purpose. On the night in question Jones and his wife took the truck for the sole purpоse of visiting Jones’ mother in Anaconda. On this trip he consumed county gasoline and oil and had no аuthority from his superiors, the board of county commissioners, to use the truck.
The position taken by аble counsel for the plaintiff is ingenious ; it is presented upon the assumption that Jones, in his caрacity of superintendent of the county farm, is a public officer, citing
Tucker’s Appeal,
Conceding the correctness of the rules contendеd for, it does not follow that the conclusion reached is tenable. Initially, the premise on which the argument is based is not supported by the single case cited; that case but holds that “oversеers *368 or directors” of the county poor, who are the duly elected members of the boаrd of county commissioners in certain counties in Pennsylvania, are, in view of the powers and dutiеs conferred upon them, “public officers” whose salaries cannot be increased during thе term for which they were elected.
Jones was not a public officer within the definitions of that tеrm recognized in this state; he was merely an employee of the county. Here “the board оf county commissioners are vested with the entire and exclusive superintendence of the poor” (see. 4521, Rev. Codes) ; they may establish and conduct a poor farm (sec. 4534, Id.); the discretion in the conduct and control thereof is theirs, acting, if necessary, through agents.

v.
Cooney,
The “officers” оf a county are enumerated in section 4725 of the Revised Codes, and the test for determining whethеr an appointee is a public officer has been declared by this court.
(State ex rel. Nagle
v.
Page,
We recognize the rule that a presumption has the effect of evidence, and that whether sworn testimony to the contrary is sufficient to rebut it is a question for the triers of fact, but this rule is subject to the exception that “where the facts proved are overwhelmingly against the presumed facts and рermit of but one rational and reasonable conclusion,” it becomes a question of lаw for the court and not one of fact for the jury.
(Nichols
v.
New York Life Ins. Co.,
Herein certain of the presumptions relied upon are inapplicable because of the fact that Jones was not an offiсial of the county, and the remaining ones “fade away” in the face of positive testimony to the contrary and render a directed verdict in favor of the county proper.
(Monaghan
v.
Stand
*369
ard Motor Co.,
It has always been the rule in this jurisdiction that, even though there be conflicting evidence in the record, if the еvidence is in such a condition that the court would be in duty bound to set aside any verdict that might be rendеred thereon for the plaintiff, the court may direct a verdict for the defendant.
(McIntyre
v.
Northern Pacific Ry. Co.,
The court did not err in directing the verdict.
Judgment affirmed.
