28 THE OAK. 



upon the window-panes in mid-winter ! The mosses 

 of the living oak are of precisely the same kind. 

 In their tender and elegant sympathies they make 

 no distinction between the overthrown tree and 

 the tree that stands in its pride. One of their 

 most exquisite specialities is that, like ivy and the 

 faithful wallflower, they are companions alike of 

 life and death, oftentimes adorning the one with

 are nearly five hundred trees of the wavy-leaved

 most cases the green covering is from ten to twelve
