Menzie’s spruce, like that of Douglas, was long since collected by the English botanists who 
visited the Columbia, and is already introduced into cultivation in Europe. 
It grows most abundantly and attains the largest size on the coast near the mouth of the 
Columbia, forming there the greater part of the forest. 
It never attains dimensions so gigantic as those of A. Doicglasii, hut forms a tall and very 
strict tree, of which the foliage is more rigid than that of any other American abies. The 
leaves are so rigid and acute as sometimes to prick the skin like needles. The cones, where I 
have seen them, never exhibit the appearance presented in Xuttall’s figure, hut are much more 
slender, and with eroded bracts, as represented in the figure.

The western arbor vitae is undoubtedly the finest species of the genus. It resembles somewhat 
the species so common about the great lakes, T. occidentalism but is not only a much larger and 
finer tree but the foliage is handsomer. 
It grows in the greatest abundance in most parts of Oregon ; within the range of my obser¬ 
vation, much more abundantly and attaining the largest size near the coast; though said by 
Nuttall to grow in perfection on the Upper Columbia. The finest trees I saw of it are in the 
vicinity of Port Orford. It there constitutes an important part of the forest, and attains a size 
scarcely inferior to that of the sugar pine or Douglas’ spruce. 
The foliage, from the regularity of the divisions of the minor branches, and from the accuracy
