Synopsis by Mark Deming
This short educational film, produced by the United States Department of Agriculture, offers a look at just how many products are made from wood, and stresses the consequential importance of forest cultivation. The film is best remembered today for a cameo appearance by Stan Laurel and Oliver Hardy, in which the comic team show off a number of wood-based items; it was the first and only time Stan and Ollie appeared in a full-color film. Pete Smith, who was best known for his short comedies for MGM, serves as narrator.
