and much esteemed for building, especially for water- 
works. There are three main varieties of this pine, 
viz.: P. L. Poiretiana, in Italy; P. L. Austriaca, in 
Austria; P. L. Pallassiana, on the borders of the 
Black Sea. The tree grows best in calcareous soil, 
but also in poor, sandy soil, where, however, the tim- 
ber is not solarge norso good. It yields all the pro- 
ducts of P. Silvestris, but in greater quantities, being 
perhaps the most resinous of all pines. 
Pinus Mertensiana, Bong. — California Hemlock 
Spruce. North-west America. The wood is white 
and very soft, but is often used for building. The 
tree is from one hundred to one hundred and fifty 
feet high, by a stem diameter of four to six feet. 
Pinus mitis, Michx.—Yellow Pine of North Amer- 
ica. In dry sandy soil, attaining a height of sixty 
feet. Wood durable, fine-grained, moderately resin- 
ous, valuable for flooring. 
Pinus monophylla, Torr. and Frem.—Stone or Nut 
Pine of California, on the Sierra Nevada and Cascade 
Mountains, six thousand five hundred feet. The 
seeds are edible, of an almond-like taste, and con- 
sumed in quantity by the natives. Height of tree 
only thirty-five feet; thickness of stem eight to ten 
inches. 
Pinus montana, Du Roi. (P. Pumilio Henke.)— 
On the Alps and Carpathians up to the highest points, 
covering large tracts, and thriving on the poorest soil. 
The tree, which grows about twenty-five feet high, 
in favorable localities fifty, yields much oil of turpen- 
tine. ‘The wood is used for carving and for firewood. 
Only available to advantage for our highlands. 
Pinus Montezumez, Lamb. (P. Devoniana, Lindl.)
