Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A yarder is piece of logging equipment which uses a system of cables to pull or fly logs from the stump to the landing. It generally consists of an engine, drums, and spar, but has a range of configurations and variations such as the Swing yarder. The early yarders were steam powered. They traveled on railroads, known as "dummylines" and the felled trees were dragged or "skidded" to the railroad where they were later loaded onto rail cars. Popular brands were: Willamette, Skagit, Washington, Tyee, or Lidgerwood and Clyde built by Clyde Ironworks in Duluth, Minnesota. Although these machines appear to be large and cumbersome, they were true workhorses of their day. The Clyde was capable of retrieving logs from four different points at the same time. Each cable, or lead, was approximately 1000 feet in length. Once the logs were attached and a clearance signal was sent for retrieval, they could be skidded at a speed of 1000 feet per minute (1MPH = 88 fpm = 26.8 meter per minute) this is around 10 mph. Working conditions around these machines were very dangerous.
