The members of the fire company as well as many others started pouring water on the flames at 1:30 a.m. but by 2:30 a.m. the buildings were almost entirely consumed. The efforts to put out the fire were hampered by a brisk northwest wind that blew sparks toward homes and started many small fires.
Damage from that fire was about $10,200. One of the buildings destroyed by the fire was the home of the Lake Park News. The paper, however, only missed one issue due to the blaze.
