p. 112. On the banks of the river Noatak [Bedford Pirn), and on those of the Buckland. 
The northernmost tree on the north-western coast of America, forming forests on the banks of the 
river Noatfik, being nearly seven degrees further north than the limits of the woods extend on the oaatcm 
shores of the continent. Some of the trees measured bj Lieut. Bedford Pirn, R.N,, were from twenty to fifty 
feet high, and from four to five feet in circmnferenee. Sections of them are preserved in the Museum 
of the Eoyal Botanic Gardens, Kew. The specimens in the Herbarium differ somewhat in aspect from 
tliose grown in more genial climates, and two botanists of eminence expressed the opinion that my spe- 
cimens did not belong to Pimis alba, but to some allied, perhaps new, species. With due reverence for 
an opinion coming from ciuch quarters, I stQl feel convinced that the Spruce of Western EskimAUX-laml 
is the true P. alha of Aiton, and that the strange aspect is merely owing to physical influence, which in 
this case, as in many others, stamps upon the species the true arctic character. The only species to which 
P. alha seems to be allied is P. SUchejms, Bong. (Endl. Synop. Conif p. 123), but the scales o{ the cone 
of that plant are always toothed, while those of P. alba are entire.
