The ferns are the most showy, and generally attractive of 

 the cryptogams. Many of them are tall feather-shaped 

 plants, their broad spreading fronds, the ornamental and im- 

 perial plumage of the earth, producing the perpetual impres- 

 sion of beauty. Some of them are humble and lowly plants, 

 but possessed of exceeding delicacy and grace. The more 

 imposing species frequently occupy extensive spaces of the 

 mountain heath, forming brakes, or matted continuities, 

 which cover the surface sometimes to the entire exclusion

 spreading pinnse, or leaflets, looking to the south, or facing 

 the sun, and held in file by the strong attraction of his rays. 

 Some of the species are shy and retiring in their habits, and 

 are rarely seen ; others are found almost as common as grass, 

 occupying large spaces, growing in the woods and swamps, 

 while others invest the rocks and cliffs, festooning their edges 

 and surfaces with rare and picturesque fringes and wreaths.

The ferns seem to be attracted to mountains, and, from
