458 COAL MINE IN BOHEMIA. 
A similar abundance of distinctly preserved 
vegetable remains, occurs throughout the other 
Coal fields of Great Britain. But the finest

the contrast of the coal-black colour of these 
vegetables, with the light ground work of the 
rock to which they are attached. The spectator

into the forests of another world ; he beholds

which began and terminated in times of which 
these relics are the infallible Historians. 
Such are the grand natural Herbaria wherein
