There is a curious grave at Evergreen Cemetery in the West River neighborhood of New Haven, Vermont, the United States. It’s a small grassy mound with a large slab of concrete placed at the top. This concrete block has a small fourteen inch square glass window facing towards the sky. The glass window is hazy and has beads of water hanging on the underside from condensation, and you can’t see much inside. But back in 1893, you could have peered inside and straight into the decomposing face of Timothy Clark Smith.
