The plump capsules of F. flavicans are much less differentiated from those 
of F. hygrometrica than those that are shrunken, but even in the plumpest stage 
the mouth is noticeably less oblique and in the shrunken stage the differences 
in the obliquity of the mouth and outline of the capsules are very striking. I 
suspect, however, that the differences are not always so apparent as in the speci- 
mens photographed, which were considered fairly typical. 
I tried to soak out some capsules of F. hygrometrica to show the difference 
in the same specimens when wet and dry, but the setae began to twist as soon 
as the specimens were put on the stage to be photographed and twisted so rapidly 
that the result was only a blur. I have frequently had the same trouble with 
fresh mosses where the time of exposure was from three to five minutes and the 
specimens separated from each other and the substratum. 
Aside from getting suitable specimens the problem of getting good moss 
photographs resolves itself largely into the two problems of lighting and depth 
of focus. Next number is planned to contain a discussion of these problems, 
and in the advertising columns will be given a list of species of which prime 
fruiting specimens are needed for photographing.

Round Mountain Lake is situated in the western part of Maine, in the 
township of Alder Stream, Franklin County, about 20 miles from the Canadian 
border, and adjoining the Megantic Club’s preserves. The lake itself lies at 
2300 ft. alt., with a row of five Round Mountains, averaging 3000 ft., on the 
west. The highest peak in the vicinity is Snow’s Mt., 3986 ft., about 5 miles 
distant, but this was not visited by the writer. The lake is about half a mile 
long, and perhaps a quarter of a mile wide, rather shallow, spring-fed, and con- 
tains one beaver and some fair trout. At the outlet is a beaver dam with a 
small pond below it, and about this is a young bog where the Sphagnum is just 
beginning to gain a foothold. 
The only peculiarly peat-bog hepatics were the two early arrivals Mylia 
anomala and Cephaloziella elachista; this latter, in fact, is not dependent upon
