Slabs are the cut off round sides of the log as well as bits and pieces that can't be sold as lumber. These are used as fuel for the mill and sometimes as fuel for the locomotives. The Argent Lumber Company had many slab cars, but they were just for one purpose. The Hebard Cypress Company would have had a car that could haul slabs back to the woods from the mill, but could haul something back from the woods as well. A gondola is a good car for that purpose. Needless to say this car is freelanced.
