Found anywhere else, the section of wire in the lower part of the photo wouldnt be worth much speculation. But it was found along the route of an early cross country telegraph line that used Leffert''s Hooks. The thin diameter of the copper wire wouldnt have held together on any great spans. The earliest telegraph lines were wired with copper but as it would fail due to stretching and contracting with heat and cold (to say nothing of wind and icing) iron wire soon replaced the copper.
