6 FILLING AND TAMPING 



In setting a pole it should he " trued " and held in position with pike-poles until 

 firm, the dirt being filled in evenly around it and thoroughly tamped as the filling 

 progresses (Fig. 13). The coarse soil or gravel should be put in last. The filling ean 

 be done by one man, and the tamping by two men. After the pole is set and the hole 

 filled, about 6 in. of earth should be closely packed around the pole above the ground. 

 Poles set in solid rock should have rock fragments firmly wedged in around them.

Section 56 Bracing and Guying 



The use of braces and guys is obviated in many cases by a proper amount of rake, 

 but either bracing or guying will be necessary in the following cases : 



(1) On any pole oil a curve or at a corner where the pull exceeds 30 ft. 



(2) On poles at each side of a crossing over roads and railway rights of way. 



(3) On the two end poles of spans between 300 and 500 ft. 



(4) On the poles at either end of spans above 500 ft. 



(5) On very steep slopes. Anchor guys may preferably be used in these cases, 

 or a head guy from the to-p of one pole (below the lowest bracket) to the base of the 

 pole next above it. 



(6) On alternate poles in exposed positions. 



(7) On poles in swamps or on loose ground (where necessary.) 



(8) On poles on both ends of high-tension transmission line crossings. 



(9) On the first and last poles of a line. 



1 'BRACES 



Braces (Fig. 14) should be at least 8 in. in diameter at the butt end, cut slanting 

 at the top to fit close to the pole but the pole itself should not be cut. They should
