Hew successions of change and of activity. Set 
free from their long imprisonment, they return

of our existing forests ; and having for a while 
I’esumed their place in the living vegetable king-

to the use and benefit of man. And when 
decay or fire shall once more consign them to the

perpetual ministration, in the economy of the
