One night, walking in the countryside near Prijedor in Bosnia, I found a solitary glow-worm, with its amber-green light, under some grasses. I picked it up and carried it on my finger where it glowed like an electric opal on a ring. When I approached the house the other lights competed too strongly, and it put its own out.
In the bedroom I placed it on some leaves on top of the chest of drawers. When I put the light out, the glow-worm glowed again. At the back of the dressing table was a mirror which faced the window. If I lay on my side I saw a star reflected in the mirror and the glow-worm beneath on the chest of drawers. The only difference between them was that the light of the glow-worm was slightly greener, more glacial, further away.
