Bark inte Liverpool for the three years ending 3lst July, 1894, 
have been as follows :— 
Some teria 281 Bales.

has been described by Prof. Oliver as Eucommia ulmoides. The 
bark is the only part used, and is inuch esteemed by the aoe

which was committed to writing probably as early as the first 
century : our era
