speaking of globular formations in pond water, in a small pond fed by a
very silty stream I noticed a cluster of silt-covered lumps, each about
the size of a grape, the whole cluster about the size of a cantaloupe,
anchored at one end to the mud, waving freely and gently at the other. I
didn't like to commit any invasive investigation, does anyone know what
this is? Someone's home? Someone's family?
