Logs

Logs are the base form of wood in the Lumber Tycoon 2. Upon chopping a tree, you will be able to carry this around the map (Usually to a Sawmill or to the wood dropoff at the Wood-R-Us )After putting it in a sawmill, the value increases 10 times (data from my VPS experiments shown on the Wood page) in planks. Logs have an outer bark layer and the core. The bark is usually darker colored than the core, and the core is always the color of it's planks.
