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 of sled runners, so that the whole may 



be drawn along the stack by attaching a team 



A Derrick Stacker 



with six-tined Jackson or California fork. The derrick is substantial, and guy 

 ropes are not necessary. Stakes driven into the ground around 

 the base hold the derrick in place
