Frullania eboracensis is common throughout the range, and 
has the usual habitat of trees and rocks. Along the North 
Shore Range it is common on the cliff walls. Along the Cop¬ 
per Range it is found only on trees. 
F. Brittoniae is rare. It was collected at Solon Springs on 
a living hut fallen tree growing about 20 feet from the ground, 
and on a fallen dead birch above Indian Spring at Lake Neba- 
gamon, Douglas Co. Wis.; also at Gordon, Wis. in a dense cedar 
swamp on living trees. Near Carlton, Minn, at Thompson on 
the St. Louis River an immense concrete dam has diverted the 
water through a canal to the lower levels. The season of 1910 
was usually dry and when the place was visited in September 
and October practically all the water was thus diverted. For 
the first time perhaps the river channel was dry, and one could 
walk dry shod down the west gorge over burnished boulders, 
and collect along the water and spray lines of the river wall. It 
was here that F. inflata was found, covering the perpen¬ 
dicular wall of the shady side of the gorge with patches four and 
six inches across, now dry and dusty with silt. It will undoubt¬ 
edly disappear from the higher surfaces and become rare in a 
few years. Growing within a few feet, on the higher shaded 
rocks where collected F. inflata , F. Asagrayana ■, F. eboracensis, 
and F. OaJcesiana growing on rock. This is the first record ob¬ 
served of such habitat for F. Oakesiana. As the ledges where
