It is needless to saythat the saving involved by being able to move this line rather thanrebuild at the new location was an item of considerable importance. The above illustration shows the derrick in position to pull a poleout of the ground, the top of the pole being temporarily side-guyed. In Fig. 4 the pole is shown after having been pulled out of theground and placed on top of the embankment. The derrick is readyto shift and slide the pole back to the new hole. Two men and thechauffeur pulled and completed the moving of this pole with its loadof six arms of wires in twenty-five Fig. 5—Derrick Operating Under Difficult Conditions As a further example of the usefulness of the derrick in pole work,Fig. 5 shows a job where the pole derrick was operated under ratherunusual conditions to erect a pole at the side of the road where thepole hole was dug under water and the pole erected in barrels. It USE OF LABOR-SAVING APPARATUS would be difficult to pike a pole into such a hole because there isnothing against which to rest the butt while raising it. Another important function of the derrick is that in connectionwith the resetting of poles or the removal of abandoned poles when itis necessary to remove the butts. The slow and laborious process ofpulling the pole out of the ground with a jack or other equipmentis practically eliminated as the derrick, properly handled, is capableof doing the greater part of this work in much less time, more economic-ally and with greater safety to the men. In addition, it might be pointed out t
