with a pole raising derrick makes possible the digging of the hole and 

 the erecting of the pole with but one setting of the truck. 



With the boring machine from 30 to 80 poles per day can be set in 

 their holes by a force of three men. This, of course, does not include 

 straightening the poles and backfilling the holes. To do this amount 

 of work with manual labor only would ordinarily require from 15 to 50 

 men. It is of particular interest to note that the more difficult the 

 digging, exclusive of rock, of course, the greater the saving by using

the machine. It might be mentioned that one of the most important 

 features of the boring machine is its ability to bore holes through 

 frost thus enabling a more uniform apportionment of pole work over 

 the entire year. This feature is also of particular value in connection 

 with the restoration of service subsequent to sleet storm breaks in 

 winter at which time hand digging is in many cases a practical 

 impossibility. 



Fig. 8 illustrates the ability of this 4-wheel drive outfit to negotiate 

 difficult ground conditions. In this instance one rear wheel has 

 dropped into a hole while traveling over a plowed field covered with 

 snow. It required only a few minutes to lift the wheel by moving 

 the turn table so that the auger was just behind the buried wheel, 

 then raising that corner of the truck by forcing down the auger with
