DECIDUOUS ORNAMENTAL TREES.

those rugged mountains are invested.” We have seen the 
Mountain ash here, displaying itself in great beauty, mingled 
with a group of hemlocks, from among the deep green foli- 
age of which, the coral berries of the former seemed to shoot 
out ; their colour heightened by the dark back ground of 
evergreen boughs. 
The American Mountain ash, (Pyrus Americana) is a 
native of the mountains along the banks of the Hudson, and 
other cold and elevated situations in the north of the United 
States : on the Catskill we have seen some handsome speci- 
mens near the Mountain House ; but generally it does not 
grow in so comely a shape, or form so handsome a tree 
as the foreign sort. In the general appearance of the leaves 
and blossoms, however, it so nearly resembles the European, 
as to be thought merely a variety by some botanists. The 
chief difference between them appears to be in the colour of 
the fruit, which on our native tree, is copper coloured or 
dull purplish red. It may probably assume a handsome 
shape when cultivated. 
The Sorb or Service tree, ( Pyrus JSorbus ,) is an interest- 
ing species of Pyrus, a native of Europe, which is sometimes 
seen in our gardens, and deserves a place for its handsome 
foliage, and its clusters of fruit ; which somewhat resemble 
those of the Mountain ash, and are often eaten when in a 
state of incipient decay. The leaves are coarser than those 
of the Mountain ash, and the tree is larger, often attaining 
the height of 50 or 60 feet in its native soil. 
The White Beam, (Pyrus Aria,) is another foreign species, 
also bearing bunches of handsome scarlet berries, and clus- 
ters of white flowers. The leaves, however, are not pinna- 
ted, but simply serrated on the margin. It grows 30 feet
