THE NEWER EVERGREEN ORNAMENTAL TREES.

The only variety which approaches hardihood in this part of the 
country is the A. imbricata, (Chili pine), which when planted in 
sand and gravel on well drained soil, and in a shady wood, succeeds 
quite well — that is to say, we have specimens which withstood 
the severe winters of 1855-6-7, with no other protection than 
a few hemlock boughs, and came out perfectly bright and 
green in the spring, even with their leaders uninjured for the 
past three years. Both sun and wet are fatal to it, and in 
situations where there are no side-hills sloping to the north, it 
should be planted on the north of buildings, on little mounds, 
with at least the lower foot in the holes filled with stones for 
drainage. Mr. Saunders informs us that there are some fine 
healthy trees near Baltimore, w r ith upright shoots. At Wash- 
ington, a specimen planted, in 1852, by Mr. Downing, in the 
public grounds has succeeded admirably, though a little injured 
by the winter of 1856. It does not stand at Newport, and at 
Flushing, and in New Jersey succeeds only when sheltered ; 
so also at Cincinnati. In Augusta it is eminently successful. 
The other varieties, A. Bidwili , A. Brasiliensis , A. Cunning- 
hamii, and A. excelsa (the beautiful Norfolk Island pine), are 
too tender for any but our extreme Southern States, though all 
thriving, except excelsa, in the open ground at Augusta, Ga. ; but 
for purposes of ornament to cultivated grounds in summer we 
know nothing more distinguished than these different varieties 
grown in tubs and protected in winter in a common green-house. 
Biota. 
The Chinese or Eastern arbor vitas, so called to distinguish 
it from Thvja, the American or Western arbor vitae. 
B. orientalis, (Chinese arbor vitae), which was but compara- 
tively new, when this book was first published, has not proved 
quite as hardy or as available as was at first hoped ; all our 
reports, from different parts of the country, speak of it in most 
cases as not quite hardy, at any rate doing better in protected 
situations. Even in New Jersey it is sometimes killed to the 
ground in severe winters. Our best returns are from Washing- 
ton, where it is reported as very commonly planted and per- 
fectly successful. At Woodlawn, N. J. (Mr. Field’s), there is a
