FLORA OF THE MOUNTAIN. 255 



surfaces of different kinds of rock, at the same time stretch- 

 ing up through a considerable calorical scale, or height of 

 climatal variations, 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- 

 laborers in this department, have reported three hundred 

 and ninety-four indigenous species, of which two hundred 

 and fifty-five are common to Europe.
