Query: Since it's highly flammable, what do people often use little pieces of longleaf pine tree stumps for?
Context: Structures built of fat lighter are almost impervious to rot and termites; however they are very flammable. Stumps of old longleaf pines are often dug, split into small pieces and sold as kindling for fires. Stumps thus dug may actually remain a century or more since being cut.
