and greatly aids the picturesque effect when mixed with other 
trees, or in the shrubbery. It is propagated by engrafting on the 
common Beech, and may be obtained at the nurseries around 
Philadelphia. A fine specimen exists at Landreth’s. 
Fraxinus, Ash. — The F. americana , and F. excelsior , the 
European, are large forest trees, well adapted for shade and 
ornament. The F. excelsior -pendula, or weeping ash, is a 
curious tree; its branches incline downwards, and with training 
may be made to form a living summer-house, or other fanciful 
structure. 
Gymnocladus canadensis, Kentucky Coffee Tree , is of pecu- 
liar aspect; having but few secondary branches, the limbs show 
conspicuously, when the foliage has fallen ; and produce a good 
effect. 
Lireodendron tulipifera, Tulip Tree. — This is one of the 
many grand productions of the American forest; no less admired 
for its clear polished foliage, than its showy tulip-like flowers. 
It were needless to say one word in its praise, so generally is it 
known and admired. For street planting it perhaps grows too 
large, unless where there is great breadth of foot-path, or the 
buildings recede from the line of the street. In such situations 
there can be nothing better: around massy public buildings, its 
effect would be imposing. 
Maclura aurantiaca, Osage Orange. — An indigenuous 
tree, first discovered by Hunter and Dunbar, on the banks of the 
Little Missouri; and named by Nuttall, in honour of our towns- 
man, the late Wm. Maclure, Esq., “a philosopher whose devo- 
tion to Natural History, and particularly to the geology of North 
America, has scarcely been exceeded by Ramond or Saussure, in 
Europe.” There are several fruit-bearing trees around Phila- 
delphia, reared by the late Mr. McMahon from seed, procured 
by Lewis and Clark when on their expedition. It is dioecious, 
having the male and female flowers on different plants. A large 
solitary tree, at the Landreth nurseries, produced for several suc- 
cessive years, some bushels of fruit, which prematurely fell, after 
attaining the size of an orange. The expedient was adopted of 
tying it on the branches with staminiferous flowers, obtained from 
a distant tree; the result was entirely successful, and many 
thousands of young plants have been reared from seed thus per- 
fected. The experiment has been repeated again and again, as 
we have been assured, and with invariably the same effect. 
The foliage of the Maclura is of a deep green, highly polished, 
and from abounding in acrid juice, is seldom attacked by insects. 
The young plants are armed with formidable spines, and from 
the experiments made, seem admirably suited for hedges: much 
more so than the thorn. A hedge of it at Mr. Maupay’s, but a
