pine. The rate of growth in Britain is, except in very favourable situations, 

 slower than that of most European pines. Nevertheless, in the climate of 

 London, it will attain the height of 12 or 13 feet in 10 years from the seed 

 When planted singly, like most other pines, it forms a branchy head ; but, 

 when drawn up among other trees of the same species, it has as clear a 

 trunk in Britain as in America. The wood is more employed in America 

 than that of any other pine, serving exclusively for the masts of the numerous 

 vessels constructed in the northern and middle states. The soil and situation 

 ought to be favourable, otherwise the tree will not thrive. Seeds are procured 

 ill abundance ; and the plants, when sown in spring, come up the first year, 

 and may be treated in the nursery like those of the Scotch pine.

 Height 150ft. to 200 ft. 

 rarely 215 ft. Intro- 

 duced in 1827. It has 

 not yet flowered in Eng- 

 land. Native of the 

 north-west coast of 

 North America, where 

 it was discovered by 

 Mr. Douglas ; and in- 

 troduced into England 

 in 1827. 



The species to which 

 this pine is most nearly 

 allied, Douglas observes, 

 is undoubtedly P. Stro-

 ever, it is extremely 

 different in station, habit, ,, Jlr />.<,-.) Lambert
