LOGGING 
The maintenance of a pole road is low. The chief items aside 
from the occasional replacement of a pole, are the removal of 
splinters from the rails, usually with a spade, and greasing the 
rails with skid grease. One man can maintain 2 miles of track 
on half time. 
The cars are built with a heavy framework of sawed timbers 
mounted on four wheels, each of which is about 42 inches in

diameter with a slightly concave face, a 4-inch flange on the inner 
side and a 2-inch flange on the outer. Each wheel turns on a 
2-inch fixed axle provided with a side play of 6 inches so that the 
wheels can adjust themselves to the inequalities of the rail and 
the uneven gauge. 
The bunks are 10 feet long and from 10 to 12 feet apart. A 
reach which passes through the body of the car and projects 2^ 
feet beyond the bunks serves as a point of attachment for the 
draft power. 
Cars of this character drawn by two horses will carry 1400 
board feet per load. A team will haul loaded cars from, 8 to 10 
miles daily.
