On November 26th Mr. W. D, Graddon and I searched
together, and despite frost and heavy rain on the previous
day found twenty species. The route was from High Beach
to the "Wake Arms," onwards nearly to Ambresbury Banks,
then to the Theydon Road between Oak Hill and Jacks Hill,
and back to the "Wake Arms." The hunt occupied five hours.
A damp hollow near High Beach, with fallen willow trees and
decaying leaves among brambles, yielded ten species, and
another fallen willow lying partly in a bog near Jacks Hill
