A few years ago I bought a small box containing ‘magic lantern‘ slides, small glass plates with photographs on them, at an antique store in Minnesota. They’re essentially for use in the slide-projector of the late 19th century and early 20th century, a way to share photos with an audience. Five plates are in […]
Once we’ve gotten past the dip compasses, the next two pages are the most important (at least according to this catalog) books for any prospector to have.
