SPECIFICATIONS AND PRICES 



For commerical purposes, poles are classified by 5-ft. lengths, top 

 diameters, and sometimes by the diameter at a specified point, usually 

 6 ft. from the butt as in chestnut. The minimum length is generally 

 regarded as 20 ft. and from the poles run in 5-ft. lengths up to 75 ft. 

 or more for special purposes. Practically two- thirds of our poles are 

 from 20 to 30 ft. in length as these are the sizes most in demand. Only 

 about one-fifth are from 30 to 40 ft. in length, one-twentieth from 40 to 

 50 ft. and only i to 2 per cent exceed 50 ft. in length. 



The telegraph and telephone companies purchase about 75 per cent of 

 all the poles used. A good share of the remainder are purchased by the 

 electric railroad and the electric light and power companies. The steam 

 railroads purchase only about 6 per cent of all the poles. 



Specifications are prepared by the pole associations or by the tele- 

 phone, telegraph and other companies to classify the poles according 

 to dimensions, shape, freedom from defects and appearance.

 in the ground (6 ft.) not being taken into account in arriving at sweep, tightly stretch 

 a tape line on the side of the pole where the sweep is greatest, from a point 6 ft. from
