This species of Spruce Fir is nearly related to the pre- 
ceding, it is, as yet, a very scarce tree in the gar- 
dens.

unfit for making spruce beer.

V. V. The Jersey Pine, Pitch or Scrub Pine, is of 
middle size, straggling growth, and full of resin. Its 
branches are tougher than any other pine I know, and 
might be used for several useful purposes if its wood 
was not so apt to an early decay. A. B, Lambert, Es({. 
in his n)agnificent Monograph on this interesting 
and useful genus, made similar observations, which 
the younger Michaux in his Arbres forestiers, p. 60, has 
taken up as a point of criticism. On this subject 
Mr. Lambert favoured me w'ith his observations re- 
specting this and some other remarks made by Mr. 
Michaux, which [ think proper here to in.sert ; it is 
in the following words : “ The criticisms made by 
Mr. Michaux on my ^ Description of the genus Pinus’ 
are so inaccurate, that I did not think them worth my 
notice before, nor should I now, were it not to pre- 
vent Mr. Pursh from being misled by them, though I 
believe he is already well aware of their fallacy ; I shall 
therefore beg of him to insert a few observations 
on the different subjects to which they respectively 
belong, if they meet with his approbation and con- 
inops^
