dried, 48 lb. 80z. It is employed for all the different purposes to which that 
of P, A‘ria is applicable, and is considered rather preferable as fuel, and for 
charcoal, The fruit is brought to market both in England and France ; and, 
when in a state of incipient decay, it eats somewhat like that of a medlar. 
As an ornamental tree, its large green buds strongly recommend it in the 
winter time, as its fine large-lobed leaves do in the summer, and its large and 
numerous clusters of rich brown fruit do in autumn. It will grow in a soil 
not poorer, but more tenacious and moist, than what is suitable for P. A'ria ; 
and it requires a sheltered situation. It seems more liable to the attacks of 
insects than that species, and does not thrive so well in the neighbourhood of 
London. It is propagated exactly in the same manner as P. A‘ria. There 
being no varieties, it does not require to be continued by grafting.
