Paul North was wondering about the "square tower" visible in the background in the second photo.  All transmission lines that I have seen rotate the phases every so often, and use a different style pole or tower to do this.  This was very important when next to telegraph and phone lines that were sharing the same real estate. For one thing it kept induced hum low on the phone lines. I have often wondered why they need to rotate or transpose the wires when there is no other lines near them. Art I
