This is the full length video (27 mins). The new part starts at about 6:20 and follows through to cutting the lumber and shipping it out. "This film survives as a record of the long log business. Highly detailed scenes, filmed year-round, are uniquely enhanced by the original script, written to be read with the silent footage in the 1930's. The soundtrack is brought to life by Tim Sample, narrator and renowned Maine humorist, in the role of the filmmaker, Alfred Ames." From Stump to Ship: A 1930 Logging Film
My great-grandfather and his brother were "timber cruisers" circa 1875. They were the middle-men between the owners of big tracts of trees and those who needed them. Most of the "cruising" they did was for the railroads in Virginia. A railroad would plan to build a big wooden trestle and they would locate the trees and broker the deal between the land owner and the railroad. At that point they were done; someone else would get the business of cutting down the trees and getting them to the mill.
