SECT. XIX. LISTS OF TREES, &C. 333 



Bay, the common plain sort is rather tender, and 

 requires a situation sheltered from bleak winds ; but 

 the variegated and double flowered sorts are ten- 

 derer still ; and as they rarely succeed well abroad, 

 they are commonly considered as green-house 

 plants. 



Cedar, the Bermudian, is tender whilst young, and 

 should have a favourable situation afterwards. 



Fir, there is a variety of each species, denominated 

 from the number of leaves, and the shape and colour 

 of the cones. The balm of gikad, and hemlock, 

 sorts, are the lowest growers. To et the .seed from 

 the cones, lay them before a good tire, so as not to 

 scorch them; and if they come not out well, after 

 heating this way, bore a hole up the middle, and 

 drive something of iron in to split them. 



Oak, the evergreen sorts are excellent limber, and 

 very ornamental in pleasure grounds : See page 27. 

 The red excrescences upon the kermes oak, are oc- 

 casioned by insects making insertions in the bark for 

 depositing their eggs, which causing an extravasation 

 of sap, it there condenses, and forms the little gra- 

 nulous substances, used for scarlet dying. 



Pine, there are several other sorts of less estima- 

 tion. The Ifaymouth and torch pines are the 

 loftiest, and the Carolina swamp the lowest growers. 

 To get out the seed, observe what is said above, as 

 the pine cones are harder to open than the firs. 



Pyracantha requires some support of stakes, pales, 

 or wall, though it may be trained as a standard bush, 

 or form an hedge impregnable. It is very pretty 

 when in full fruit ; but it so often misses bein| so, 

 through bad pruning, that it is got much out of re- 

 pute: See page 179. Tt does best in a dry poor 

 soil, and an eastern aspect. Young cuttings, in 

 June, will strike, being potted in good earth, and set 

 in the shade till autumn, and then plunged in the
