The mast is held in place by guy ropes from "the top. Leading to the right may be 



seen the rope to which is attached a team of horses. The base of the 



derrick is in the form cf sled runners, so that the whole may 



be drawn along the stack by attaching a team.

are not necessary. Stakes driven into the ground around the 



base hold the derrick in place.
