herbaria of the eastern states, and many are mentioned by Dr. Young
in his report. Dr. M. L. Fernald has summarized the known results
of the expedition as follows. "Though they brought back the first
representative collection of Katahdin plants, they apparently got
none of the rarer species and the data upon their labels are unfor-
tunately incomplete."'
  The second step towards the execution of the survey was taken
September 28, when Dr. Young reached Castine and employed "Mr.
Bridges" to assist him for several days.
  Dr. Young had a wide circle of correspondents among the leading
botanists of the period, among them Prof. William H. Harvey, the
eminent Irish algologist. Prof. Harvey had encouraged him to dredge
on the Maine coast for algae, believing from the rocky indented nature
of the shores with their deep reaches, that it would prove one of the
most fruitful regions on our Atlantic coast for these plants.
  Aided by Mr. Bridges, he spent most of the time at Castine in
dredging in water of varied depths. October 5 he embarked on the
Revenue Cutter "Veto," Lieut. S. C. Foss commander, for a short
cruise among the islands of East Penobscot and Jericho Bays. On
the date mentioned they harbored in the lee of Big Deer Island, where
Aaron again used the dredge. From this berth they sailed to Burnt
Coat, now called Swan's Island, where they harbored one night. The
dredge was used here, both in the harbor and in deeper water outside.
  From Burnt Coat they sailed to Isle Au Haut Thoroughfare October
7, and Dr. Young, Lieut. Foss and the Pilot, Mr. Eaton, landed on
Isle Au Haut and ascended "the mountain"; Aaron noticed alders,
"low alder, (alnus crispa) not over two or three feet high, apparently
distinct from the two species common in our low lands;" "Oakesia"
[= Corema] "Conradii, Kalmia latifolia"2 and a few common plants.
  Returning that night to the Northwest Harbor of Great Deer Island,
on the following morning they visited the serpentine quarry on the
island, then giving promise of commercial importance. Aaron learned
that on frequent occasion fires had raged, destroying the yellow birch
woods on the island, formerly a valuable source of fuel to the settlers.

  SMr. N. T. Kidder, authority on the flora of Isle Au Haut, informs the writer,
that this plant is not now known to occur on the island and raises the pertinent ques-
tion of a possible mistake in Identification of the species. Dr. Young seems to have
been acquainted with the three species of Kalmia found in the State, having described
them all in the Flora of Bangor in 1843. Considering the violent admiration given
this showy plant both for floral and evergreen decorations, wherever it occurs in
isolated colonies, it seems possible that a small colony existing in 1847 may have been
extirpated.
