No authority has been cited and we are unable to discover any allowing the city clerk to withhold the pension mon'ey on his own initiative, even though he is thus *97 attempting to pay a debt of the pensioner.

It was, therefore, error to quash the alternative writ of mandamus.

By the Court. — Judgment reversed.
