The Conductors. The question of copper or aluminum, to be usedfor conductors was given full consideration, the de-cision being in favor of the latter. One of the objec-tions urged against aluminum was that the metalbeing soft the conductors would have to be handledvery carefully as they would be liable to be seriouslydamaged if they should be pulled over rough prove or disprove this claim a length of about1000 ft. of cable of approximately the size which wouldhave to be used was secured. On the right of wayof the Medical Lake Railway a place was found wherenumerous jagged rocks and rough boulders stoodabove the surface of the ground; a team of horseshitched to one end of the cable pulled it back andforth twice over this ground withou
