Got these off a guy who found them on Hunker Creek (7 KM South of Dawson City, Yukon). They were near a power plant that supplied power to the massive dredges that scoured the creek beds for gold in the early part of the 1900's. I'm assuming they were part of a communication network, since they are 108, Dominion - 9's (090) in a light sage green. Note how thick the pins are and the galvanized wire. Not horribly exciting glass, but a neat bite of history.
