Trees, Shrubs and Vines 
bitter cold, then coaxed back by tropic heat, the shift- 
ing forests tell a tale of more remarkable migrations than 
ever were accomplished by bird or beast. The stupen-

by these buried trunks, only make the more mysterious 
the ultimate destiny of this globe, if commensurate with 
the infinite pains and ingenuity, and ages long of fire 
and ice, consumed in preparation.
