There is a blue lantern kind of thing in my back yard. It has been there for several years and I can only guess at how it got there. I can only guess at what it is; hence I call it a lantern thing. It looks like a blue glass cylinder with large brass fittings on either end. It may be a humming bird feeder or some such. I have never looked at it closely and have no idea if it contains anything. I may have even stepped over it without picking it up to look at it more closely.
