X Marks The Snail

Three years ago, on a quiet, wet April morning, there was a
profunderance of snails in the "yard" area behind where I work. They
always turned up in droves when the ground was damp. I don't know what
came upon us, but we decided to mark a few of the snails on their
shells, using (non-toxic) "Tipp-Ex" with x's, y's and z's, in a
science-experimenty fashion.

Today, the day after a drizzley bank holiday, an old friend turned up,
making his way back to the flowerbed from the drying yard.
