many species of mollusks might inhabit Liberty Island---or, perhaps, Central
Park, or Golden Gate Park. In some of our semi-wild areas bird counts are
done on a regular basis by groups devoting a Sunday to the task. Has a group
ever done the same for mollusks? Might be a nice task for some club getting
bored with their usual programs.

I heartily agree, with the reminder that the group collect nothing but
photographs and drawings, no specimens. Small, heavily trafficked parks
cannot withstand the love of collectors.
