ranging from New England to Virginia, and generally found on 

 light, friable, and sandy soils. In such it grows to 70 or 80 feet 

 in height. This is the well-known " Pitch Pine " of commerce. 

 Is quite hardy here, and gi'OAvs at about the same rate as the Scots 

 pine ; hence, is worthy of being more freely planted. Its resinous 

 shoots and small clusters of cones make it very ornamental and 

 attractive. 



P. Sahiniana (Sabine's, or the Nut Pine). — Introduced in 

 1832. Habitat, California, where it grows to a moderate height. 

 It is veiy hardy, but its wood is not in much repute. It has very 

 lai'ge cones, and the leaves are from 11 to 14 inches long. As an 

 ornamental tree, the rambling habit of its growth and the long- 

 twisted leaves give it a very picturesque appearance. 



P. Strohus (the Weymouth Pine). — Introduced in 1705. A 

 native of Canada and the Eastern United States, and a good 

 timber tree, often reaching 100 to 150 feet in height. Here it 

 is perfectly hardy, and grows very well on dry porous soil, but is 

 more useful as an ornamental than a timber tree. 



P. Tceda (the Loblolly Pine). — Introduced in 1713. Habitat, 

 Florida, Virginia, Carolina, etc. This is the Virginian " White 

 Pine " of commerce, and a valuable forest tree in its native 

 country. From this tree the resin is extracted by making in- 

 cisions in the bark, fx'om which it flows freely. Frankincense is 

 said to be produced from the resin, and to be composed of two 

 kinds of resin, mixed with oil of tui'pentine. 



Among less valuable timber ti'ees, but most of which are useful 

 ornamentally, are the following Pines : — P. A2nilcensis, P. 

 Ayacahuite,P. Balfouriana, P. cembroides, P.Devoniana,P. excelsa, 

 P. Jlexilis, P. Gerardiana, P. haleioensis, P. inops, P. koraiensis, 

 P. leiophylla, P. longifolia, P. Massoniana, P. montana, P. muri- 

 cata, P. oocarpa, P. parviflora, P. patula, P. pinea, P. pungens, 

 P. resinosa, P. Russelliana, P. serotina, P. Teocote, P. Torreyana, 

 and P. tuherculata. Some are natives of Mexico and Central 

 America, while others are from India, China, Japan, and other 

 tropical or semi-tropical countries, and consequently less hardy 

 than those from temperate latitudes. The chief characteristics of 

 some are their form of growth, of others in the size and arrangement 

 of their cones, and, in several instances, in the variegated colour 

 or peculiar arrangement of their leaves. In the sunny south of 

 England and Ireland, and mild south-west coast of Scotland, the 

 planter should add most, if not all, of them to his collection, but
