2 Mildred Martin, administratrix of the estate of R.G. Martin, deceased, sued the City of Altus, to recover damages resulting from the death of R.G. Martin, her husband, alleging failure of defendant to furnish deceased, its employee, a reasonably safe place to work and that on the 20th day of January, 1947, Martin injured his left arm as a result of such negligence, from which injury he died on October 28, 1947. Defendant denied generally such allegations, set up defenses of contributory negligence, assumption of risk and unavoidable accident, and also pleaded that the city in the operation of its sewage booster plant, where the deceased was injured, was exercising a governmental function. Trial was had to a jury; the trial court denied defendants motion for directed verdict; the jury returned a verdict in favor of plaintiff. Defendant appeals.
