bog here was grown up with white cedars (Chamaecyparis thy- 
oides). Another drive through miles of pine forest, here trees 
thirty feet or more in height, brought the group to a station for 
the climbing fern (Lygodium palmatum). In a meadow that had 
been mowed earlier in the season the fern was growing abun-

Further on in the woods the plants climbed to a height of two 
or three feet among the bushes. Another drive, and the party 
hunted for the Massachusetts fern (Aspidium simulatum) in a 
boggy place. With it was found the Virginia chain fern ( Wood- 
wardia virginica). In another place the two species of Wood- 
wardia (virginica and areolata) were found, growing together 
near a brook. The Virginia chain fern—as pointed out by Dr. 
Wherry—often becomes a troublesome weed in the cranberry 
bogs, almost the only fern of our region to become troublesome 
in any way.
