Short Log
A Short Log is half a Log. You saw one Log into 2 Short Logs on the Sawhorse, or dig out a tree stump with the shovel for 1 to 3 of them (stumps need Farming mastery 2 or, for the largest, 5). Unlike a Log, it fits in your backpack.
Short Logs are what the Chopping Spot works with: one Short Log becomes 10 Firewood or 10 Wood wedges. Firewood is the only fuel for the furnace, the kiln and the Distillation Cube, and Wood wedges are needed to split stone, so every furnace batch and every Piece of stone goes back to Short Logs.
