P plars in general, when young, are very ornamental, and 

 many of them form fine trees wnen they have attained to a 

 large size. There appears to be a great prejudice against 

 some species of the Poplar, but, as a tree of rapid growth, 

 and calculated to promptly form an ornament, it is not sur- 

 pa^ed. With regard to the Athenian Poplar, I have to re- 

 mark, that the one which is usually sold by that name in this 

 country is incorrect. 



Juniper, or Junifierus. Under this head, I will confine 

 my remarks to the species of Juniper commonly planted for 

 ornament, and to the Savin. The Red Cedar, so common in 

 our country, and which belongs to the same genus, it is un- 

 necessary to describe ; and most of the other species of Ju- 

 niperus, esteemed as ornamental trees, will not support the 

 wint* rs of this latitude. Many ot them are, however, well 

 calculated for the S( uthern states, and on that account have 

 been introduced by the autlor, and descriptions of them will 

 form part of a more enlarged publication hereafter 



Junifierus suecica, or Sivtdiah Junifier. I consider the 

 one commonly cultivated tor ornament to be of this species. 

 It is a very hardy shrub, and will grow in almost any soil. 

 It is most admired when trained in a conical form, which is 

 done by tying up the straggling branches compactly in au- 

 tumn ; and if this course is regularly pursued, the shrub 

 will retain the form thus given to it. They may also be 

 clipped to any shape, to suit the fancy of the owner. Trained 

 in the foregoing manner, I have seen them form a regular 

 and beautiful cone to the height of from 16 to 18 feet ; and, 

 through all its minor stages, it is very ornamental, from its 

 perpetual verdure and unique appearance. The leaves 

 are narrow and sharp pointed, and grow by threes on the 

 branches ; the flowers are small, of a yellow colour, and 

 make no figure ; they are succeeded by blueish beif ies$
