Spar Tree: A tree topped and limbed for use in high-lead logging with a donkey.In this b/w picture the rigger has just topped the tree in preparation for setting up the rigging. The top of the tree is falling away to the ground some 60 feet below.
The "Show" was the logging operation where the logs were taken for milling and / or loading onto trucks. Over the years the method of getting the logs to the show evolved from oxen to "donkeys" (see our Getting them out story). Notice the extent of the rigging in the model of the "high lead show" (built by Moe Fossum of Mission).
Rigging: The assortment of swivels and hooks that fasten between the mainline and haulback line to which the chokers are attached.
Rigging Crew: All the workers out in the woods involved with yarding the logs to the landing.
Mainline: The line used to yard logs. It has a larger diameter than a haul-back line.

Mobile Spar Tree: Used the same way as a stationary spar tree. It is mounted on tracks and is able to move from one logging show to another, thus saving the time needed to rig a stationary set up.32
This is a 'bug' (switch) used by the whistlepunk to sound the whistle.1940
Mission, British Columbia

Whistlepunk's Bug: In the days of the "donkey", the whistlepunk was the signalman who relayed messages to go ahead or stop, to the donkey engineer, from the "hooker". In the early years, the whistlepunk would have had a long tightly strung line and used a system of pulls, jerks and whistles to serve as signals.As steam power gave way to electricity, the line was replaced by a long electrical wire - much like an extension cord. The whistlepunk's bug with two electrical conductor prongs was attatched to the end of the cord. When the prongs were squeezed together, the closed circuit could transmit a signal. The pattern of signals caused by squeezing and releasing the bug then replaced the system of jerks on the line.
