our southern cities, it has become so completely acclimated 

 as to appear almost indigenous ; but in the vicinity of New- 

 York and Philadelphia they are not numerous: here and 

 there, however, a fine tree may be found from 10 to 15 feet 

 in height and a large one in the garden of the author pro- 

 duces its curious flowers, and matures its seeds regularly. 

 The foliage of this tree is of a most delicate and beautiful de- 

 scription, being numerously pinnated, and of a very pleasant 

 green. They are not sensible to the touch, but like others 

 of this class close at night, putting on the appearance of 

 rest and sleep. My advice to persons who wish to possess 

 this fine Acacia is, to protect the plants in latitudes north of 

 the Potowmac until they are four or six feet in height, by 

 means of a covering of wood or straw, and raising the earth 

 next the surface j after attaining this size, they will seldom 

 be injured by cold, unless to the north of New York. 



Weefiing Birch^ or Betuta fiendula.- This tree has been 

 often described for its fine effect in Scottish Highland 

 scenery, where, with the Larch, the Roan, and the Labur- 

 num, it serves to gladden and beautify the mountain cliffs. 

 The aspect of this species when young greatly assimilates 

 to that of our Common White or Poplar Leaved Birch, 

 both in respect to foliage and to the whiteness of its bark, 

 and it then maintains an upright growth for it is not until it 

 Jias attained to some size that its young shoots begin to droop, 

 and gradually assume a weeping appearance. It is after 

 they have arrived at this state that they are particularly or- 

 namental. A tree, now standing on the author's grounds, 

 is about 35 feet in height, but they surpass this in their na- 

 tive regions. It is no way difficult as to culture, and after 

 once planted, will need little attention. With regard to soil, 

 it will succeed in almost any, but like all other trees, its 

 growth will be advanced or retarded according to the good- 

 ness thereof, 



Purslane 7V<?<?, or Atrifilex halimus. This shrub grows 

 to the height of five or six feet, forming by its spreading 

 branches a broad head ; the young shoots are covered with 

 a white smooth bark, that of the older ones is of a light grey 

 colour ; the leaves are soft, white, silvery, and look well at 

 all times, even in winter, as it retains its foliage at that sea- 

 son, and forms a fine contrast to the generality of evergreens. 

 It is often injured in severe winters in this latitude, but a few 

 degrees further south it will be free of such danger.
