THE NEWER EVEEGEEEN OENAMENTAL TEEES. 489 



The only variety which approaches hardihood in this part of the 

 country is the A. imhricafa, (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, with 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. Cwnning- 

 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 difierent varieties 

 grown in tubs and protected in winter in a common green-house. 



Biota. 



The Chinese or Eastern arbor vitse, so called to distinguish 

 it from Thvja, the American or "Western arbor vitse. 



B. orienlalis, (Chinese arbor vitse), 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. A.t Woodlawn, N. J. (Mr Field's), there is a
