 climatal i'ariationi<, it would be natural to expect that the 

 mountain would reveal extensive botanical affinities in this 

 and other departments. Here, to the common observer, 

 the variety would appear to be infinite, but the drilled eye 

 of the naturalist soon classifies and catalogues them all. 



Of the Order Musci, William S. Sullivant and his co- 

 laljorers in this department, have reported three hundred 

 and ninety-four indigenous species, of which two hundred 

 and fifty-five are common to Europe. 



No introduced Euroi)ean species are recorded. Some 

 cursory observations of the mosses of the Alleghany give
