272 TIIE NURSERY. [March. 



the seeds are ripe. All the kinds take freely by grafting on one 

 another. 



The Tilia amerieana, or American lime or Linden tree, together 

 with every other species of the same genus, is easily propagated by 

 layers, or by sowing the seeds in October or November, or in March, 

 if preserved in dry sand till that time. Sow the seeds on an even 

 surface, clap them in with the back of a spade, and cover them a 

 little better than half an inch deep. 



The JVyssa integrifolia, or upland tupelo-tree, or sour-gum, is 

 propagated by seed, suckers, layers, or cuttings; if by seed sow 

 them immediately when ripe, covering them an inch deep; some of 

 them will come up the spring following, but many not till the second 

 year. The better way would be to prepare them as directed for 

 haws, and in the ensuing March examine them; if you then find 

 many showing symptoms of vegetation, sow them; if not, let them 

 remain till that time twelve months. 



Deciduous Cypress, White Cedar, and Arbor Vitx. 



The Cuprcssiis disticha, bald or deciduous cypress, grows to an 

 enormous large size, the foliage of which is uncommonly beautiful 

 during the summer months. It is propagated by sowing the seed in 

 March, in beds of good mellow earth, covering them half an inch 

 deep; they must be kept very free from weeds, and when two years 

 old transplant them from the seed-beds into nursery rows. 



The Cupressus tkyoides, or white cedar, is propagated by sowing 

 the seeds, which are very thin and flat when taken out of the cones, 

 in boxes of light earth, taken from swampy ground, and covered 

 about the eighth of an inch, or a little more, with loose rich mould 

 sifted evenly over them; they must have frequent sprinklings of 

 Avater, and when up, and the heat increases, the boxes must be 

 removed into the shade. You must keep them very free from weeds, 

 as many of the seeds will not grow till the second year. "NY hen 

 they are two years old transplant them into nursery rows, in moist 

 light swampy ground. 



The Thuya occidentalism or American arbor-vitas, is propagated 

 by layers and cuttings, or by sowing the seed as directed for the 

 white cedar, with this difference, that it will not be necessary to 

 procure swampy earth for it, as it thrives best in upland. 



The Thuya oricntalis, or Chinese arbor-vitas, maybe propagated 

 in like manner as the occidentalis. 



All the above kinds, if raised by seeds, will require some pro- 

 tection during the two first years, from very rigorous frosts. 



Pities and Firs. 



The pines and firs, though ranked under the same genus, (Pinus,) 

 may be easily distinguished from one another, as the leaves of 

 the former come out by two, three, or more, from the same sheath, 

 and those of the latter singly. In the cedar of Lebanon and 

 larch, they arise in bunches from the same bud, spreading out 

 every way.
