WATSONTOWN -- A passerby reported a fire in a house along Musser Road in Delaware Township Saturday night, according to fire officials.

The 9:15 p.m. fire burned itself out by the time firefighters arrived on the scene, Doug Funk, deputy fire chief for the Warrior Run Area Fire Department, said.

He said the house was filled with smoke when firefighters arrived, and fans were used to ventilate the structure. About 40 firefighters from Warrior Run, Montgomery, Muncy Creek Township, Hughesville and Milton responded to the blaze.
