Common on the North-West coast and in the Rocky Mountains, also 

 in Hudson's Bay ; grows even to a large tree in the 54 at an elevation of 

 7800 feet above the level of the sea.

Near the Boat Encampment of the Columbia River in 52 17' 19" ; 

 more plentiful on the aqueous flats of Cedar River in 48 23' 00". Sparingly 

 seen and of diminutive growth in the 46 on the North-West coast.

Plentiful on low swampy ground about Hudson's Bay, Lake Winnipeg, 

 and Lesser Slave Lake, and on low aqueous flats of the Rocky Mountains, 

 on the low marshy islands of the Columbia River above Tongue Point, 

 and not uncommon in similar situations along the coast to Nootka Sound.

Abundant on the woody parts of the North-West coast, fully larger 

 than any found on the Atlantic side of the Continent from the 43 to 

 the 49 ; not in the interior nor in the valleys of the Rocky Mountains.

Flowers in May ? 



Leaves solitary, flat, linear, entire, stiff, blunt, with a minute concavity 

 at the apex, ascending, somewhat two-ranked, so densely imbricated that 

 the lower side of the branch is completely hid, very glaucous, seven- 

 eighths of an inch long. Flower unknown. Cone solitary, cylindrical, erect, 

 six to eight inches long, one and a quarter in diameter, dark brown. 

 Scales round. Bractea scarcely exceeding the scale, oblong, obtuse. 



The present tree, among the many highly interesting species by which 

 it is surrounded in its native woods, in point of elegance justly claims 

 the pre-eminence. The trees are straight, one hundred and seventy 

 feet high, two to six feet in diameter with a white smooth polished bark. 

 An open-growing tree, sparingly clad with wide-spreading horizontal 

 branches placed in regular whorls round the tree, the distance between 

 the whorls diminishing towards the top. The cones are always on 

 the highest branches, near the top like P. Picea 5 and P. bakameaf 



The wood is soft, white and very light, containing but little rosin. 

 An inhabitant only of the mountains, seldom if ever seen to arrive at 

 any considerable size lower down on the hills than 5000 feet above the 

 level of the sea in the 46 and 48 N. Lat. 



Common on a chain of mountains that run nearly parallel with the
