Lumber is one of the most important materials in Imperialism and Imperialism 2.

Produced in a great power's lumber mill from timber (or in a village after suitable development of your industry), lumber is essential, along with equal amounts of steel, for
expanding buildings and for building transport capacity (freight cars).
Some (particularly early) ships need lumber in their construction.
Any lumber not required for the above processes can be turned into furniture in the furniture factory. That is essential for population expansion, but is good also for selling to minor nations.
