As most readers are aware, Cumberland can claim the doubtful 
privilege of possessing the wettest spot in the British Islands. And in 
the combination within a small geographical area, of elevation, mildness, 
and, as regards the western portion of the county, atmospheric humidity, 
we have conditions essential to the occurrence of a rich and interesting 
moss-flora. 
Elevation alone, however, when it is represented by bleak moorland 
is not necessarily a favourable condition. Of this we have our share in 
Cumberland, but there is also a large area of highly elevated rock which 
affords habitats for arctic, or semi-arctic, species of mosses. 
It may be well to remark here that the British moss-flora is con- 
nected for the most part with that of Scandinavia ; and in the mountains
