4. Street railroads, § 131*—when evidence shows due care on part of occupant of automobile hilled in collision with street car. In an action against an interurban railroad company to recover for the death of a passenger in an automobile struck by one of defendant’s cars, evidence held sufficient to warrant the finding that plaintiff’s intestate exercised due care while riding in the automobile at the invitation of the owner and driver thereof, where he was from the country, probably unfamiliar with the streets and location, and the owner and driver was a resident of the vicinity and had long experience as a driver and acquaintance with his surroundings, and there was nothing in the situation to prompt a prudent, sensible man to interfere with the operation of the car by its owner or attempt to control him in crossing intersecting streets or in other places of more or less danger.

The exclusion by the court of defendant’s offer, in the presence of the jury, to show that the motorman of defendant’s car, who failed to appear as a witness for defendant upon defendant’s subpoena and fees tendered, said when he refused to attend that his mother was dead and was to be buried that afternoon, was not prejudicial error.
