The poles are of chest-nut, having tops 8 ins. in diameter and are spaced approxi-mately 110 ft. apart, with the face of the pole at top of rail10 ft. from the center line of the track. The poles were distributed by train and after beingframed, graded and armed on the ground were erected inplace by the use of a steam derrick mounted on a flat illustrated. This method of setting poles proved quite asatisfactory one and on a line where the work would not be of brackets, a novel and very economical device was consisted in an arm having a wire head guy on one.
