wood Nursery, is also an excellent collection, containing 

 many species of the newer kinds. 



At Princeton, N. J., in the excellent collection of R. S. 

 Field, Esq., may be found some of the largest and best 

 specimens of the rarer Conifers to be seen in the North- 

 ern States. The planting of these grounds was commenc- 

 ed some twenty years ago, and the oldest specimens of 

 Norway Spruce, White Pine, etc., have already attained 

 the height of fifty feet. The greater portion of these hav- 

 ing been planted along the northern boundary of the 

 premises, now present an impassable barrier to the cold 

 winds of winter, and to this may be attributed the success 

 with many of the half-hardy plants in this collection. 

 The proprietor shows a well-deserved partiality for the 

 Norway Spruce, White Pine, European Silver Fir, White 

 Spruce, and American Arbor Yitse, and justly deprecates 

 the doubtful merits of the Balsam Fir. 



Among the rarer trees to be found here is the Cedar of 

 Lebanon, (Cedrus JLibani,) the largest of which is now 

 about forty feet in height, and has been fruiting for several 

 years. This interesting specimen is frequently injured 

 slightly by the winter, but not sufficiently so to impede 

 its growth. 



We take pleasure in recording the success of the Prince- 

 ton specimens of Plnus excelsa, for notwithstanding it 

 seems unwilling to thrive in many localities, its success 

 is almost certain here, in spite of an occasional injury to 

 the leading shoots. The finest plant is now twenty feet 

 high, and beautifully proportioned. Other Pines are not 

 so satisfactory, although receiving as much care and at- 

 tention. Most of the rarer kinds from the Rocky Moun- 

 tains and westward are to be found in the collection. The 

 Long-leaved, or Southern Yellow Pine (P. Australis) is 

 here, apparently at home, and preserves its elegant bright 

 green color ; one plant is fifteen feet high. Pinus Cembra
