Dear sir
I was gladdened on my return from my last
expedition for this season, with the receipt of your kind letter of the 20th.
I am happy to kind that my plants reached you, + that some,
as the Empetrum were acceptable. The specimens which I then sent were
broken from my own, as I had no duplicates, but I have collected
abundant specimens this summer in Plymouth, + can now send you
a good sized plant + the ripe fruit, which last you mention as desirable.
The Plymouth pl. [plant] I now find to have "trunks prostrate, wtih assurgent
branches" as you descr. the N. Jersey pl. [plant] when I thought it "erect", I had 
not seen it growing, + drew my opinion from the habit of what I now
find to be only the branches. The pl flowers they say in Plymouth exceedingly
early. This must also be the case with our E. nigrum, which I could 
not find in fl. [flower] even in June of this year. The ripe fruit of this last I have
twice gathered in Aug. on the White Mts. + found it full as agreable (to
me at least, because less insipid) as that of Rubus Chamaemorus or Vaccinium
uliginosum. If I do not mistake L. enumerates among its effects when eaten
in considerable quantity - "tremulentiam" [?] - a curious virtue, but I 
did not test it. And this reminds me to speak of the fruit of Laiserpa hispidula
of your Fl. Amer. I have repeatedly gathered + eaten it. It is a white berry
of about the oblong shape of the fruit of Vacc. uliginosum + thinly sprinkled with
