76 WOODY PLANTS OF MASSACHUSETTS. 
There are several pines, natives of Europe, which might be 
introduced with advantage into this country. The most valu- 
able of these 1s the Scotch pine, (Pinus sylvestris,) or Scotch 
fir, as it is usually called, the only one of the genus which 
grows naturally in the British Islands. It also grows through- 
out the north of Europe, and 1t is from this pme, that the masts 
and other most valuable timber of Norway and the shores of 
the Baltic are obtamed. The English ship-builders esteem the 
wood as superior to that of any of the American pines. This 
tree grows with as great freedom and luxuriance here as any 
of our native trees. Several stocks are to be seen at the Botanic 
Garden in Cambridge, where they have kept pace with the white 
pine, the pitch pine, and the hemlock. The Scotch fir has a 
striking resemblance to the pitch pme. Itis a more beautiful 
tree, and differs m having its leaves, like those of the Norway 
pine, in twos. 
Another is the cluster pine, (P. pinaster,) a native of the 
south of Europe, much cultivated in England as an ornamental 
tree. It is a variety of this tree which has been employed so 
successfully in France to cover and fix and turn to advantage 
the tracts of moving and barren sands on the coast. 
Several pines, natives of the western coast of this continent, 
would probably be propagated without difficulty and be found 
of value for their wood. Such are the heavy pme (P. ponde- 
rosa), from the Northwest Coast, remarkable for the great 
weight of its wood; Sabme’s pine (P. Sabiniana), from the 
mountains of California; and particularly the gigantic pine 
(P. Lambertiana), from the northwest country, in latitude 43°. 
This is nearly allied to the white pine.
