An early Tuesday fire destroyed a portion of the former Carroll Sales building in Mason City at 600 Fourth St. S.W. Fire departments from Mason City, Rockwell, Manly and Clear Lake responded to the call. "I got a call about 1:40 (a.m.), when I got here all I could do was stand and watch," said Latham. Carroll Sales opened in 1936 and was a wholesale feed distributor to elevators, feed stores and co-ops and also had a booming warehousing business. Mason City businessman Tim Latham recently purchased the now vacant property which is at 600 Fourth St. S.W., next to Latham's Furniture/Mattress Outlet.
