IRFD, 2012, e-mailed report.



Frederick W. Schueler, of the Bishops Mills Natural History Centre, sent in his report via an e-mail attachment. In the e-mail, he says,
*nothing worthwhile under the rocks, unfortunately, but lots on the shore, which was mostly sand. See the attached report. Maybe I should have gone someplace else.
And here's his report.
