Pinus inops, Solander. 



Eastern North- America. The Jersey-Pine. A tree, content with 

 harren soil, attaining a height of 40 feet, available for fixing drift- 

 sand on coasts. Easily disseminated. Remarkably rich in resin, 

 hence to be classed with pines most desirable for sanitary planta- 

 tions. Wood reddish -yellow. P. Virginiana (Miller) is by far the 

 eldest name. 



Pinus insignis, Douglas.* (P. radiata, D. Don.) 



California. A splendid dark-green pine, fully to 100 feet high, 

 with a straight stem, occasionally 8 feet in diameter. It is the 

 quickest-growing of all pines, a seedling one year old being strong 

 enough for final transplantation ; it has been noticed to grow fully 

 5 feet annually in light soil near Melbourne. Mr. J. Dickinson 

 found it to attain a height of 70 feet, with a stem-girth of 5 feet, 

 in 13 years at Port Phillip. The variety radiata, with branches 

 arising only towards the summit and therefore supplying long clear 

 trunks, has grown near Ballarat in some instances in ordinary soil up 

 to 100 feet in 25 years [Lowe andLaidlaw]. Although Cupressus 

 macrocarpa grows nearly as fast, that tree is not so indifferent to soil 

 as P. insignis, which will brave even stagnant humidity in stiff soil. 

 Preferable in mild climes for street-planting to trees with annually 

 deciduous leaves, as the small yearly fall of foliage does not choke 

 gutters and drains, nor becomes so offensive in moist decay ; thus 

 even of sanitary effect. Most extensively distributed through the 

 colony of Victoria and also some other parts of Australia since 1859 

 by the author of this work, not so much as a timber-tree, "but to 

 impart quickly and uninterruptedly a magnificent verdure to towns and 

 landscapes, and to afford early shelter. Needs shelter against gales. 

 According to the Hon. Winter-Irving it will endure exceptional 

 exposure to 118 F. in the shade. Even more apt to catch fire than 

 most pines. In the United Kingdom it suffers greatly from the attacks 

 of the Pine-Beetle, Hylurgus piniperda [Lawson]. The wood is of 

 inferior technic value ; but this tree can be utilised for obtaining tar 

 and pitch. It bears exposure to the sea at the very edge of the coast. 



- Produces fruit-cones only at somewhat advanced age. Mr. J. Kruse, 

 on the author's suggestion, subjected the foliage to distillation, 

 obtaining oil in 0-01 quantity of 0'845 specific gravity, of 293 F. 

 boiling point, and of a pleasant penetrating odor, reminding of 

 Geneva-gin. Prof. Don having named and described this tree under 

 two names simultaneously, the later name, given by Douglas, may 

 remain adopted, although not the oldest. 



Pinus Jeffrey! , Murray. 



California. A pine, to 150 feet in height; stem-diameter to 4 

 feet. Hardy at Christiania, Norway. Recommended particularly 

 for rearing on slopes of higher mountains, as it suffers from any 

 drought. The wood serves in the trade as coarse lumber. The
