August 24th.—Visited the beautiful cemetery of Laurel. Hill about 
four miles N.W. of the city on the banks of the Schuylkill, one of the 
lions of Philadelphia, and much resorted to in the summer seaso 
uring which stages (omnibuses) run at short intervals through the in 
to carry passengers thither. Though not very extensive, the grounds 
are laid out with taste in walks and shrubbery overlooking the river, 
towards which it slopes precipitously on that side. A common shrub 
used to ornament gardens and grounds in this and other parts of 
America, is the Burning Bush (Zuonymus atropurpureus) which has 
acquired its name from the profuse display in autumn, of its large 
crimson capsules and the scarlet arils of the seed lighting up as it were 
the broad deep green foliage. It is the American representative of Æ. 
latifolius, as E. Americanus is of E. verrucosus of Europe, but is a still 
larger and handsomer species than the first of these spindle-trees. The 
second (F. Americanus) is often seen in cultivation with our British Æ. 
Europens, which thrives extremely well. 
Walked from Laurel Hill to Mount Peace, the delightful residence 
of my kind friend R. Ralston, Esq., whose house was freely open to me 
by a general invitation from its hospitable and liberal owner, so long as 
I continued at sierra In the a? siaod VP were several 
noble Tulip trees left st he planted timber, the only now 
existing denizens of the long dines destroyed rimæyal forest which 
the axe has spared. Considering the value of the “Yellow Poplar” 
to the coach-builder and joiner, the escape of these forest veterans, so 
near a great city, from the saw-mill, is a matter both of wonder and 
congratulation. The largest Tupelo, Sour, or Black-Gum tree (Nyssa 
sylvatica) Y had yet seen, grew on this spot; a beautiful species of a 
genus as yet hardly known in British aboriculture, though deserving 
of attention for its wood, which is highly prized by the wheelwright 
for naves on account of the extreme difficulty with which it splits. 
The boles of many of the large trees at Mount Peace were clasped in 
the manner of our Ivy, by the Poison Oak (Rhus radicans), which
