Technical and Bibliographic Notes/Notas techniques et bibliographiques

The Institute has attempted to obtain the best
original copy available for filming. Features of this
copy which may be bibliographically unique,
which may alter any of the images in the
reproduction, or which may significantly change
the usual method of filming, are checked below.

The copy filmed here has been reproduced thanks
to the generosity of:

Nationai Library of Canada

The images appearing here are the best quality
possible considering the condition and legibility
of the original copy and in Iteeping with the
filming contract specifications.

L'exemplaire film6 fut reproduit grdce d la
gdnirositi de:

Bibliothdque nationale du Canada

Les images suivantes ont 6t6 reproduites avec le
plus grand soln, compte tenu de la condition et
de la nettetd de I'exemplaire film6, et en
conformity avec les conditions du contrat de
filmage.

IS

Original copies in printed paper covers are filmed
beginning with the front cover and ending on
the last page with a printed or illustrated impres-
sion, or the back cover when appropriate. All
other original copies are filmed beginning on the
first page with a printed or illustrated impres-
sion, and ending on the last page with a printed
or illustrated impression.

The last recorded frame on each microfiche
shall contain the symbol -^ (meaning "CON-
TINUED"), or the symbol y (meaning "END"),
whichever applies.

Les exemplaires originaux dont la couverture en
papier est imprim^e sont filmds en commenpant
par le premier plat et en terminant soit par la
dernidre page qui comporte une empreinte
d'impression ou d'illustration, soit par le second
plat, selon le cas. Tous les autres exemplaires
originaux sont film^s en commen9ant par la
premidre page qui comporte une empreinte
d'impression ou d'illustration et en terminant par
la dernidre page qui comporte une telle
empreinte.

Un des symboles suivants apparaitra sur la
dernidre image de cheque microfiche, selon le
cas: le symbols — ^> signifie "A SUIVRE", le
symbole V signifie "FIN".

Maps, plates, charts, etc., may be filmed at
different reduction ratios. Those too large to be
entirely included in one exposure are filmed
beginning in the upper left hand corner, left to
right and top to bottom, as many frames as
required. The following diagrams illustrate the
method:

Les cartes, planches, tableaux, etc.. peuvent dtre
film6s A des taux de reduction diff6rents.
Lorsque le document est trop grand pour dtre
reproduit en un seul cliche, il est filmd d partir
de Tangle supdrieur gauche, de gauche d droite,
et de haut en bas, en prenant le nombre
d'images n^cessaire. Les diagrammes suivants
iliustrent la mdthode.

Thans. Roy. Soc. Canada.

VI, — On Cretaceous Plants from Port McNeill, Vancotiver Island.

By Siu W. Dawson, F.R.8 and Dn. G. M. Dawson, F.G.S.

(Read May 25, 1888.)

I. — Note on the Geot,o(}y. {G. M. Dnwson.)

Tho fossil iilants referred to in the followinc: note W( re obtained at Port MeNeill. on
the north-east coast of Vancouver Island, in 188 '». The precise locality is situated on the
north shore of Tort McNeill, bearing N. 65 E. (Mag.) from the Eel Reef The beds her(>
lie at an angle of about ten degrees, or not far from horizontal ; and the ])lants are louiul
in shales or shaly sandstones about live feet above a snuill seam of coal from one to two

inches thick.

The Cretaceous rocks of the northern part of Vancouver Island appear to belong to a
basin or deposition-area distin<-t from that of the Comox and Nauaimo districts to the
south, and mor*' closely connected with that of the Queen Charlotte Islands to th.- north.
The best general stntion of the rocks in question, so far observed, is that in Quatsino
Sound, where there seem to be represented the three liigher members of the Cretaceous
section of the Queen Charlotte Islands, as it exists in the vicinity of Skid.'gati^ Inlet.
The cretaceous rocks which extend along the north-east coast of Vancouver Island, from
Port McNeill to Beaver Harbour, may in part n-present the lowest or coal-bearing portion
of the Quatsino section. A few fossil plants obtained at Beaver Ilarb. ur are Middle Cre-
taceous, and possibly referabli> to a horizon near that of the lowest beds at Quatsino. The
Port McNeill beds are, so far as stratigraphical evidence exists, probably much later
than th.'se ; but their stratigraphical position has not been fully d.'termined, aiul as no
fossils but plants have been found in them, these constitute the best evidence as to th.-ir
prciis.' age at present available. (See Part B, Annual Report Geological Survey of
Canada, 1886.)

n.— Notice of the Plants. (Sir Wm. Dairsm.)

Th«> plants from Port. McNeill are almost entirely dicotyledonous leaves, with a few
fruits. Large slabs have been procured, s.nne with very perfec -.ecimens of these leaves.
There are no ferns or cycads in the collection, and conifers are rare. The latter are lim-
ited to fragments of a SequoUi of the type of S. Langsdorjfii, bram-hlets of Torreia, appar-
ently the species T. densifolm of a fornu-r paper,' and two species of Salisburia, or Giugko.
One of these Gingkos is a beautiful little form, with leaves resembling those ot the modern
