PREFACE.

THE territory covered by this Catalogue of Plants
comprises the Island of Mount Desert and the ad-
joining islands, the more important of which are the
Cranberry Isles, Bartlett Island, Thompson Island, and the
Porcupine Islands. The Duck Islands, lying some miles
seaward southerly from the Cranberry Isles, are also in-
cluded for convenience, although having no close con-
nection geographically with the rest of the territory.
Politically it comprises the towns of Eden, Mount Desert,
Tremont, Cranberry Isles, a small part of Trenton, and a
part of Long Island Plantation, in which the Duck Isl-
ands are included. All of this territory, with the ex-
ception of the Duck Islands, is shown on the map that
has been prepared to accompany this Catalogue.

In 1880 the Champlain Society, an association of college
students formed for the purpose of field work and study
in various branches of natural science, established its
camp on the shores of Somes Sound at Wasgatt Cove,
Mount Desert Island. This Catalogue of Plants repre-
sents the final results of work begun by its botanical
department, while the introductory article on the Ge-
ology of Mount Desert represents the work of its geo-
logical department. Two years later one of the authors,
John H. Redfield, began independent investigation of

8 PREFACE.

the Island flora. In 1888 the Champlain Society allowed
its botanical work to pass into the hands of the other
author, Edward L. Rand, who, however, had been con-
nected with the work from its beginning. Soon after-
wards the authors consolidated the results of all the
botanical work on the Island, so far as they were able,
and henceforth carried on the work together, with such
assistance as could be procured from other botanists.
Although more or less incomplete, and somewhat hastily
prepared, this Catalogue is now presented, at the request
of many interested in the subject, as a preliminary con-
tribution to a Flora of Mount Desert Island. This is
done with the hope that it may serve as a means of excit-
ing interest in the undertaking, and thus make possible
a more complete catalogue in the near future.

So far as the study of its flora is concerned. Mount De-
sert has no history. We are told by the early explorers
that wild roses and beach peas were abundant, and that
is all. No botanists native to the Island — if any there
were or are — have given us information as to its plants.
All such information has come from such botanists as have
chanced to go there from a distance, usually during the
summer months only. Even of these the known list is
not long, and only few antedate the beginning of syste-
matic work in 1880. It has, furthermore, been extremely
difficult to discover the names of these botanists, and to
consult their notes and collections, although the authors
have endeavored in many ways to accomplish this. The
result naturally has been far from satisfactory. In spite
of all these discouragements, however, the work on the
Flora has been carried on with perseverance. It is now
hoped that from the very fact of the publication of pres-
ent results help may be obtained for the future that other-

PREFACE. 9

wise would have been locked up in the herbaria and
note-books of unknown workers in the same territory.

Specimens of every plant in this list, with very few
exceptions, will be found preserved in the Mount Desert
Herbarium, at present kept in Cambridge, Mass. These
exceptions, most of which are either Algae or Lichens,
are denoted by an asterisk prefixed to the name of the
species. For specimens of plants thus marked, as well as
for other plants from collectors now unrepresented, we
shall be most grateful. ^ The Philadelphia Academy of
Natural Sciences, furthermore, has an almost complete
duplicate set of the Phanerogams and Pteridophyta ; and
Dr. Carl Warnstorf of Neuruppin, Germany, has a dupli-
cate set of the Sphagna. Duplicates from the Herbarium
have also been distributed among various public and pri-
vate herbaria of the country.

Much care has been taken to make the Catalogue reli-
able. Yery few plants have been admitted to the list
except on the authority of an undoubted specimen, and in
every case of exception only on a positive affirmation by a
specialist or other botanist of high repute as to the
authenticity and identity of the lost specimen. More-
over, we have had the kind assistance of many of the
leading botanists of the country in the determination of
specimens in difficult families and genera, and in cases
of doubtful determination, as well as in the criticism and
correction of our manuscript. Prof. L. H. Bailey has
given his help in Carex and Rubus ; Mr. M. S. Bebb, in
Salix; Prof. William Trelease, in Rumex and Epilobium;
Dr. Thomas C. Porter, in Solidago, Aster, and Mentha;

^ Any correspondence relating to the Flora may be addressed to Edward
L. Rand, 740 Exchange Building, Boston, Mass., or to John H. Redfield, 216

who have done so much to add to the value and accuracy
of this Catalogue, to the various collectors whose names
appear therein, and to President Charles W. Eliot of
Harvard University, through whose interest and kindness
the publication of our work has been made possible, we
extend our sincere thanks.

Acknowledging, as we have at the outset, the incom-
pleteness of this Catalogue in many of its divisions, we
issue it at the present time to assist those interested in
the plants of the Island to the acquirement of a better
knowledge of its flora. With this end in view, therefore,
it has seemed well to include, for the benefit of specialists,
even manifestly incomplete lists of some of the Crypto-
gams. The list of Vascular Cryptogams (Pteridophyta),
the Ferns and their allies, is fairly complete ; the lists of
Mosses and Liverworts are well advancing towards com-
pletion, and the same is true of the lists of Lichens and of
the marine Algae. Very little work, however, has been
done thus far in the collection and determination of the

PREFACE. 11

fresh-water Algae and the Fungi, and it has seemed better
for the present to omit the latter altogether from this
Catalogue. It is hoped that in the near future more
attention may be given to increasing in a marked degree
our knowledge of this part of the Island flora.

July 1st, 1894.

GENERAL OUTLINE OF THE PLAN OF THE
CATALOGUE OF PLANTS.

I. The names of plants supposed to be indigenous to North
America are printed in heavy broad-face type. " Indigenous "
is but a relative term, and can hardly be employed with any
accuracy, even in its commonly accepted sense, in connection
with the flora of a comparatively small territory, without a
very definite knowledge of the facts of local plant introduction
and distribution. A list of Mount Desert plants pretending
to show the plants "indigenous" to the Island would contain
mere guesswork in many cases, and would only lead to much
confusion. It has therefore been thought better to draw the
distinction between plants indigenous to the continent and
those evidently foreign to it, and to add such notes as may
seem of value relating to the introduction within our territorial
limits, on the one hand, of North American species, and, on the
other, of species from other continents.

II. The names of plants believed to be introduced into
North America are printed in small capitals. It is to be
understood that in nearly every case such plants have been,
so far as known, indirectly introduced through other parts
of this continent into Mount Desert Island. There is very
little of that evidence of direct introduction of any of these
plants which is so common about seaports where there is
direct communication with foreign countries. This class of
plants includes both those that are fully naturalized and those
which as yet are only adventive or well established garden
escapes. For reasons already given, it will be seen that there
are no ballast plants to be catalogued.

14 PLAN OF THE CATALOGUE.

III. Synonyms are printed in Italics.

IV. The principle underlying the arrangement and nomen-
clature of the Catalogue is a very simple one, more practical
than theoretical. It is this : to follow in these respects some
manual or other work of high authority, regardless of any
fancy or preference of the authors. It seems hardly necessary
to state to any one of practical experience, that the office of a
local Flora, or of any similar work designed fully as much for
the public generally as for scientists, is not to serve as a nomen-
clator, or to present an opportunity for the author to display his
fads to his own satisfaction and the confusion of the reader,
but rather to be a help and an aid to a better knowledge
of the plants of any given region. Unless descriptions are
added, so that such a catalogue is in reality a manual in itself,
reference must be made to some well known work or handbook.
Such being the case, the authors have felt obliged to adopt
some such standard as a guide and basis for the arrangement
and nomenclature of the Catalogue,^ giving only such synonyms
as in their judgment may serve some useful purpose of identifi-
cation or of information, and making such corrections only as
do not interfere with the system of the guide adopted.

In nomenclature and arrangement, the sixth (revised) edition
of Graj'^'s Manual by Watson and Coulter is followed for the
Phanerogams (Flowering Plants) ; for the Pteridophyta (Vascu-
lar Cryptogams), and for the Hepaticae. Dr. Carl Warnstorf's
articles on the North American Sphagna, in Vol. XV. (1890)
of the Botanical Gazette, are mainly followed for Sphagnum;
while Lesquereux and James's "Mosses of North America" is
followed for the remainder of the Mosses. Tuckerman's works
are followed as far as possible for the Lichens, and Farlow's
"Marine Algae of New England," with some marked changes

1 As, however, the subject of botanical nomenclature has been given
undue prominence of late by some of our American botanists among others,
it has seemed better to the authors to discuss this subject at more length in
the Introduction. Had this not been done, it might be asked why the
rules of the so called Rochester and Madison Codes were not followed
as a standard, — an intentional omission for which there is more than ample
justification.

PLAN OF THE CATALOGUE. 15

in classification, arrangement, and nomenclature, for the marine
Algae. ^ In every case where descriptions of genera or species
found at Mount Desert do not appear for any reason in these
works, the authors have tried to give them in the Catalogue,
hoping thereby to render unnecessary any reference to works or
articles not readily accessible. It is believed that our plan has
been adopted throughout with some slight exceptions, most of
which need no explanation.

V. It has, however, been thought well to adopt throughout
the Catalogue the parenthetical citation of the original au-
thor of the specific or varietal name, a method already long
adopted by cryptogamic botanists. Thus Coptis trifolia, the
common Goldthread, was described in 1753 by Linnaeus under
the name of Hellehorus trifollus. In 1798, Salisbury consid-
ered that the plant showed well marked generic differences, and
assigned it to a new genus, Cojitis. Our plant therefore bears
the binomial, Cojitis trifolia (L.), Salisb. It must be borne in
mind, however, that the author cited in parentheses is cited
only for the specific or the varietal name in the binominal, as
the case may be, and is connected with that alone, and not with
the binominal itself. To the binominal, the name of the
author not cited in parentheses alone applies. If these dis- C/
tinctions be remembered, many of the objections that have

been so forcibly urged against this method of citation seem to
lose their weight.

VI. The term <'form" — forma — has been used for the
sake of convenience to indicate slight physiological or struc-
tural variations seeming of hardly enough importance to mark
a good variety, much less a species, and yet worthy of some
notice, perhaps of future study. Allowance once rightly made
for variation in nature, it becomes a very complex and difficult
matter to decide what is a species, what a variety, what a
form, what a variation. Without discussion of the subject, it
may be said that it has seemed best to recognize as forms sub-
stantially the same variations that are indicated by Dr. N. L.

1 Siee introductory note to the list of Algas for a fuller statement of the
plan adopted.

16 PLAN OF THE CATALOGUE.

Britton in his article '*0n the Naming of 'Forms' in the
New Jersey Catalogue." ^ It is not thought well, however, to
attach the name of any author to these so called forms, as the
line between a form and a mere variation is generally too
shadowy to call for the exercise of any judgment worthy of
recognition in the decision that one variation or another should
be dignified by the term forma. Forms should bear names for
the sake of convenience, and if properly named; that name
should be preserved to avoid confusion, if the form proves after
investigation to be a well defined variety. In such a case, how-
ever, to cite the author of the name in parentheses seems to
savor more of affectation than of common sense or utility, and
if so, why mention the author of a form at all? A line must
be drawn somewhere to check the increasing tendency to self-
glorification that can at present be so easily gratified on the
part of the amateur as well as of the professional botanist. In
this Catalogue, therefore, as has been stated, no authors are
cited for the names of mere forms. Should, however, any one
desire to know them, a goodly number may be found in Dr.
Britton's article just referred to.

VII. The usual terms common, uncommon, freq^ient, infre-
quent, occasional, rare, etc., are used to denote the relative
occurrence of the different plants. It must be remembered,
however, that these terms apply only to a plant in its proper
habitat. Because a seashore plant is "common," no one should
expect to find it on the mountains ! Where few stations are
given for any plant, it does not necessarily follow that it does
not occur elsewhere. New stations are likely to be reported
at any time for nearly all such plants. It merely indicates,
therefore, that thus far collectors have not been successful
in detecting any very general distribution of the plant in
question.

VIII. An asterisk prefixed to names of plants indicates that
a specimen of the plant in question is not to be found in the
Mount Desert Herbarium at the present time, although the
occurrence of the plant within the territorial limits is un-
doubted.

PLAN OF THE CATALOGUE. 17

IX. The abbreviations xised for names of authors will be
found in Gray's Manual, Gray's Structural Botany, or in Brit-
ton's Catalogue of New Jersey Plants. Other abbreviations
either require no explanation, or may be found in any manual
or text-book. The abbreviation " R. & E., " as may be readily
supposed, refers to the authors of this Catalogue.

X. The geographical nomenclature follows that of the map
of Mount Desert Island published in June, 1893, to accompany
this work. Its nomenclature is based on certain universal and
well recognized laws of nomenclature, among the chief of which
are the regard for priority, for firmly established custom, for
good taste, and for avoidance of unnecessary confusion. The
rules adopted by the U. S, Board on Geographic Names have
been followed as far as possible as to form, in order to secure
conformity with the Coast Survey Charts and other govern-
ment publications. Of the changes caused by these rules, the
only one that is likely to be commonly noticed is the avoid-
ance of the possessive whenever this can be done without de-
stroying the euphony of the name or changing the descriptive
application. In applying this rule, therefore, the possessive s
has been retained only where it appeared to be necessary for
euphony or to avoid misunderstanding, usually where the name
is a Christian name, and sometimes where for special reasons or
on account of peculiar usage it seemed impracticable to do
otherwise. In all cases, however, where the possessive s is
retained, the possessive apostrophe has been dropped, since the
word should no longer be considered as possessive in sense, but
as a word in itself.

INTKODUCTION.

I. Mount Desert and its Flora.

MOUNT DESERT ISLAND, called by the Indians
Pemetic, lies about one hundred and ten miles
east of Portland, on the coast of Maine, and less than half
that distance from Rockland on the western shore of
Penobscot Bay. Its coast is washed by the Atlantic Ocean
on the south, by Blue Hill Bay and its tributaries on the
west, and by Frenchman Bay and its tributaries on the east
and north. On the northwest Mt. Desert Narrows, a shallow
strait connecting the waters of these two bays, is crossed
by means of two bridges, connecting Thompson Island with
the mainland on the north, and with Mt. Desert Island
on the south. The area of the Island may be estimated
at about one hundred square miles; its greatest length
being about fifteen miles, from Hadley Point in Eden on
the north to Bass Harbor Head in Tremont on the south ;
its greatest breadth, about twelve miles, from Great
Head in Eden on the east to The Cape in Tremont on
the west. The coast line, especially of the southern and
western shores, is extremely irregular. Up the centre of
the Island for fully half its length from north to south,
through the mountain range, passes the fiord of Somes
Sound (or " The River "), a deep arm of the sea, dividing
the Island into two almost equal sections. Across the

20 INTRODUCTION.

centre from Western Mt. on the west to Newport Mt. on
the east stretches the granitic range of mountains that
has given Mt. Desert its name, rising almost from the
sea to heights varying from about three hundred to over
fifteen hundred feet. Towards the north the ground slopes
to the farming lands of Eden and the great meadow of
the Northeast Creek, and towards the southwest to the
meadows of Marsh Creek, to Great Heath and the boggy
wilderness below the Hio. Between the peaks of the
granitic range lie deep valleys, filled either by an arm of
the sea, as Somes Sound, or by a lake or pond of more or
less magnitude. These are mountain ponds for the
most part, many of them of great depth, with rocky
shores broken by stretches of sand or gravel beaches.
None of the streams are of much size, and the regularity
even of their natural flow has been greatly diminished by
the wanton destruction of the woods about their water
sheds. 1

All of these facts, however, are much better explained
by the map itself, and by the article on the geology of
the Island by Professor Davis, kindly contributed by
him for this very purpose. It is better, therefore, in this
place to make no more than the most general statements
in regard to the topography. Neither is it well to attempt
any detailed description of the flora in its relations to
these physical and geological characteristics, for as yet
the evidence seems too fragmentary and disconnected to
prove facts of much value. A few brief statements of a
very general nature, illustrated by a few examples, may
however be of interest to the botanist.

One of the most marked characteristics of the Isl-
and flora is its not only strongly northern, but arctic

INTRODUCTION. 21

character.^ On its coast, enveloped in cold fogs and
washed by waters chilled by the arctic cur/rent, it is
no wonder that arctic plants like Montia fontana and
Stellaria humifusa should find a congenial home. More-
over, this character of the flora is shown by the fact that,
with one exception, Lycopodium Selago, the mountain
plants descend to the sea level. Neither on the one hand
is the altitude of the mountain summits sufiicient to
develop an alpine flora, nor on the other hand is the
warmth and general character of the lowlands sufficient
to bring many of the plants of the middle temperate region
thus far up the coast of Maine. The flora, then, may be
said to be essentially Canadian, having close relations
with the very similar flora of New Brunswick. It also
shows, apart from its maritime character, many points of
resemblance to the general flora of the White Mountain
region. It is in its special problems, however, that
plant distribution becomes of great interest at Mt. Desert,
and it may be well, therefore, to consider a few cases by
way of illustration.

The return of vegetable life after the glacial period
must have taken place along somewhat more contracted
lines than are shown to-day. Mt. Desert was then, as
now, isolated from the mainland, but was without doubt
in a state of greater submergence. It is therefore natural
that there should exist in abundance on the mainland
many plants that are not found at all on the Island, or
are found there only very rarely. The water on the
north of the Island is not of great extent or dej^th at
present, yet it appears that some plants, especially those
with seeds not easily transported by ordinary means, have

22 INTRODUCTION.

always found difficulty in crossing it from the mainland.
This difficulty has had its effect in decreasing the Island
flora.

Again, in the development of their flora the Cranberry
Isles have shown some peculiarities. These islands, once
doubtless a part of Mt. Desert, and through it connected
with the mainland, were later submerged, and then ele-
vated again to develop their flora independently of Mt.
Desert, except so far as the flora of the smaller area
came from that of the greater, then doubtless more
advanced in the renewal of its vegetation, owing to
its greater altitude and consequent earlier elevation.
That there was some independent development is well
shown by the fact that between the Cranberry Isles and
the adjacent portion of Mt. Desert about the Sea Wall
there exist some remarkable differences in the flora, as
well as some strong points of union. Under almost pre-
cisely the same conditions, we find Corema near the Sea
"Wall, but not on the Cranberry Isles; we find Montia,
Stellaria humifusa, and Ruhus Ohamcemorus on the Cran-
berry Isles, but not on Mt. Desert ; we find Symplocarpus
foetidus and Hippuris vulgaris on the Cranberry Isles and
also on Mt. Desert, but at the Sea Wall alone. Such
evidence as this may point to the introduction of certain
plants on Mt. Desert by way of the Cranberry Isles, while
on the other hand doubtless most of the plants of the
Cranberry Isles came from Mt, Desert.

It is certainly far from improbable that the more
northern plants came to the Cranberry Isles by sea, either
from the north in later times, or from the south when
these islands first appeared above the sea at the conclusion
of the glacial period. If from the north, there would be
little opportunity for colonization on the rocky eastern and

INTRODUCTION. 23

southeastern coasts of Mt. Desert, — an opportunity, how-
ever, which would readily be presented on the low shores,
and in the coast marshes and lagoons of the Cranberry
Isles. Yet it would seem improbable that all these plants
reached the Cranberry Isles only. Montia has been found
also on the Duck Islands, and might likewise, and as
readily, be carried by ocean currents farther on, at least to
the westward adjoining shores of Mt. Desert. There in
the southwestern part of the Island similar conditions
existed for the colonization of these plants as on the Cran-
berry Isles, yet in fact they do not appear, so far as known.
If, on the other hand, they came from the south, remain-
ing behind in the progress of plant life northward after
the glacial period, and finding here favorable surroundings
for their existence, all the more we should expect to find
these plants also in the southwestern projection of Mt.
Desert Island. Here the land would be reached earlier
in the northward march, and would be found to present
the same conditions of soil and of general physical char-
acter as the Cranberry Isles. As, however, none of these
peculiar plants except Symploearpus and Hippuris appear
even on this part of Mt. Desert, the evidence at present
seems in favor of a later migration from the north, rather
than of the much earlier introduction from the south.
The whole subject is one of great interest, and will repay
careful study.

Another interesting feature of the Mt. Desert flora is
shown by the comparatively small representation of in-
troduced foreign plants, especially of weeds of cultivated
ground. Excluding garden escapes and a few plants
naturalized by intentional introduction, we find that the
number of weeds is very small in comparison with that
of similar areas in New England. The reason is a very

24 INTRODUCTION.

simple one, — the slight development of the Island for
agricultural purposes, — an explanation that is fully sus-
tained by the facts.

In earlier times very little attention was paid to farm-
ing, doubtless because the physical character of the Island
is not of a nature favoring agriculture except under
limited or somewhat expensive conditions. The surface
is mostly mountainous or rocky, the soil is usually thin
and poor, and has often disappeared as a covering, — a
result of reckless wood cutting and of the consequent
forest fires. Taken as a whole, the north of the Island
contains the best farming land ; the south, for the most
part, is too near the dominant granitic range to furnish
deep soil or level ground save under exceptional condi-
tions. Moreover, under these unfavorable conditions
there was nothing to encourage farming as a means of
support, for there was no market for garden products.
It is not strange, therefore, that fishing, lumbering, ship-
building, and other pursuits, were the more profitable
employments of the early settlers. All agricultural
operations were conducted on a very limited scale, and
for the most part involved nothing more than the cultiva-
tion of small vegetable patches for home purposes. These
patches were seldom well cared for, and were rarely culti-
vated in the same spot for more than a year at a time.
Of late years, however, it has been found profitable by
many landowners to raise vegetables to supply the sum-
mer demand at Bar Harbor and the other summer resorts
of the Island. Consequently there has been more sys-
tematic cultivation of the ground both for agricultural
and for horticultural purposes.

In the earlier days of the settlement of the Island,
therefore, we should expect to find few of those weeds that

INTRODUCTION. 25

constantly need the aid of man to secure and maintain a
foothold. Such is the case. The weeds of those days
were obliged to adapt themselves to the most hostile
conditions. If they could not do this, they lingered on
year by year wherever they could maintain a foothold,
and then almost disappeared from the flora of the Island.
Consequently these weeds were largely of native origin,
and not many in number.

But within a few years a new state of things has arisen.
Not only have the old weeds been gaining a stronger and
stronger foothold, but additions to the list are reported
every year, chiefly at Bar Harbor or in its neighborhood,
whence they spread to other parts of the Island. Only a
few years ago such common weeds as Portulaca oleracea,
Amarantus retroflexus and A. albus, Medicago lupulina,
Lepidium Virginicum.^ Mollugo verticillata, and Plantago
lanceolata were either unknown or so rare that it was diffi-
cult even to secure specimens of them. They are now
becoming more and more common, and appearing slowl}'
but surely throughout Mt. Desert. Some of these obtain
their foothold through cultivation of the soil, and all seem
to come, as many people do, because it is the fashion,
taking advantage of the increased means of introduction
afforded by the importation of foreign seed, of foreign
soil with other plants, of hay, and of the various other
methods by which weeds travel about from place to place.

This explanation, it is hoped, will show why so many
of the common weeds find no place in this Catalogue. It
also shows that at any time such additions to the flora
are likely to be reported by any botanist who happens to
examine the waste and cultivated grounds and the way-
sides of the constantly growing villages and settlements.
Of these newcomers it will be well to ascertain and note
carefully the date of introduction.

26 INTRODUCTION.

It is interesting also to notice what does not appear, as
well as what does appear in this Catalogue. It was once
said, indeed, that the flora of Mt. Desert was more
remarkable for what it did not include than for what it
did, — a statement that our present knowledge of the
flora hardly seems to justify Yet there are many impor-
tant gaps in the Catalogue that it is hard to account for in
any satisfactory manner. Its can only be said tha,t for
some reason or other these missing plants do not occur on
this part of the coast, or, in cases where they do occur on
the adjacent mainland, that they never were able to cross
the water to Mt. Desert Island. It is certain that the
latitude is not the cause, for these plants are found much
farther north. Doubtless the cold east winds and the sea
fogs may have driven back many plants trying to effect a
lodgment here ; but in that case there should be a marked
difference between the flora of the exposed southern and
eastern coasts, and that of the northwestern, central, and
northern parts of the Island. A study of the Catalogue
will show that there is some such difference, but not so
marked, we think, that it can be relied on as evidence to
any very great extent. It proves, however, that no one
can be well acquainted with the flora until he has studied
carefully the plants of the country lying north of the main
granitic belt, as well as those of the better known and
more frequented parts of the Island. .r

It may be interesting to mention some cases of these
missing plants. The Pulse Family, Leguminosce, will fur-
nish a striking instance. The Catalogue shows that the
Island flora contains only eighteen species, representing
eight genera, obviously a very insufficient representation
when we consider that shown by many points farther north
with otherwise much the same flora. Of these species, ten

INTRODUCTION. 27

are naturalized on this continent from Europe; two are
introduced from other parts of North America ; two more,
as appears from circumstantial evidence, may also have
been so introduced; leaving only four species that are
indigenous in the common sense. This would seem to
prove that at Mt. Desert there was some obstacle besides
climate which leguminous plants found it difficult to
surmount. That it is not some hostile condition at the
present time appears from the fact that when northern
species of this family are introduced on the Island they
flourish as well there as elsewhere.

Further instances are the genera Asclepias and Gen-
tiana, and many others, — of which no representative
whatever is found, — and a number of species belonging
to different genera, which are found northward on the
mainland, but not on Mt. Desert. It may be that some
day many of these missing plants will reach the Island,
but at present their absence seems as unmistakable as
it is unaccountable.

For its disappointments, however, the flora makes am-
ple compensation. For so limited and circumscribed an
area our territory possesses many plants interesting to
any lover of our New England flora, and has contributed
some forms that are of interest to the general botanist as
well. Even its most common flowers take new and unex-
pected deepness of color from the cool sea air, and are a
constant delight both to botanist and mere flower-lover.
Our work has been a labor of love, the fruit of happy days,
and the source of pleasant memories. If this Catalogue
proves a help to those for whom it is intended, and en-
ables them to share the pleasure we have gained on this
wonderful island of Mt. Desert, we shall be more than
satisfied.

28 INTRODUCTION.

11. The Map of Mount Desert Island.

Some years ago it became very evident that there was
to be great difficulty in properly indicating stations for
the various Island plants needing such limitation. While
it was necessary in some cases to make the station some-
what indefinite in description in order to guard against
extermination on the one hand by the flower-puller and
the plant-digger, and on the other by the over-zealous
botanist, yet it was necessary in all cases to give a name
to the station that should be both accurate and well
known as a matter of geographical nomenclature. To
some it may seem that this involved merely a reference
to any map of the Island to ascertain the necessary
information, but this was a solution of only a portion of
the difficulty. In the first place the two maps most
readily consulted, the Land Map of Colby and Stuart and
the Coast Survey Map, pay very little attention to the
names of the points of minor interest on the Island. As
such points are often of the greatest botanical interest,
and must be referred to, it was clear that the present
maps would not be of much assistance in these cases. In
the second place, the geographical nomenclature employed
on the Coast Survey Map, and followed in some degree
on the Land Map, is often, we regret to say, absolu+^sly
erroneous. In many a case, indeed, there is no explana-
tion whatever to account for the blunders, except that the
officers in charge of the work must have coined names for
their own use, regardless or in ignorance of the fact that
there might be names already attached to the places in
question. In other cases, by some curious mistake, names
have been carelessly transposed and interchanged. The

INTRODUCTION. 29

natural result of all these errors was to establish two
sets of names, one known to those acquainted only with
the maps, the other to those who either lived on the
Island, or knew the Island independently of map knowl-
edge. Furthermore, the matter of nomenclature was
much complicated by the insufferable tendency of sum-
mer visitors to give new names, often showing the worst
possible taste, to any natural feature that might happen
to attract their attention. Such names deserve preser-
vation only in rare cases, and should not be tolerated
for a moment unless by lapse of time or by custom the
new name has fairly superseded the old for all practical
purposes.

To remedy these evils, and to secure a standard for
citation in our Catalogue, it was decided to make as thor-
ough an investigation of the geographical nomenclature
of the Island as possible, to adopt a system of correct
nomenclature, and finally to prepare a map that should
set forth the results of our work. For over three years
this investigation was carried on, until, in June, 1893, the
map was published. If we may judge by what we have
heard ourselves, or by what has been reported to us by
others, very little fault is found with the nomenclature
adopted. It is to be borne in mind that where the nomen-
clature of our map differs from that of the Coast Survey
it is to be explained on one of two grounds: either
because the Coast Survey attached a name to the wrong
locality, or because it coined a name or substituted one
of no authority to replace a name well known and in
common use upon the Island. A very striking instance
of the error last mentioned is found in the unauthorized
use of Turtle Lake for Bubble Pond, or for the oldest
name of all, now obsolete. Southeast Pond.

30 INTRODUCTION.

The preparation of this map made necessary much cor-
respondence and much careful investigation of ancient
maps, plans, and records. Such an undertaking could
never have been brought to a successful conclusion had
it not been for the kindly interest shown and the invalu-
able assistance given by natives of the Island who knew
and loved it well. Among these helpers, many of whom we
regret to say we hardly know by name, but whose assistance,
by whatever means it reached us, we value highly, we wish
to give our especial thanks to the Rev. Oliver H. Fernald ;
to Mr. Eben M. Hamor, of Eden ; to Messrs. T. S. Somes,
George A. Somes, Thomas Bartlett, and A. C. Savage, of
Mt. Desert; to Messrs. W. W. A. Heath and C. M. Hol-
den, of Tremont; and to Mr. P. C. Stover, of Cranberry
Isles ; all of whom by inquiry, by personal investigation,
and by advice and criticism have done so much to give
the map its accuracy and merit. To Mr. Fernald, born
and brought up on the Island, and still retaining in his
residence in another part of the State his love for his
native place and his interest in its affairs, we owe the in-
spiration of this undertaking, and to his encouragement
and assistance its final accomplishment.

By the kind permission of Prof. Thomas C. Mendenhall,
Superintendent of the United States Coast Survey, we
have used the Coast Survey Map for the important physical
features, making here and there a few corrections, and
supplying a few omissions. We wish here to express
our appreciation of his courtesy, which has enabled us
to give a much better map to the public. New roads,
the town boundaries, and additional wood roads and paths
have been added, the different post-offices indicated, and
such points of interest named as it seemed would make
a map not only suitable for our purpose, but of value

INTRODUCTION. 31

to any one interested in the Island. The general rules
followed in regard to nomenclature have already been
explained in the Preface.^

It could not have been expected that our map would be
either complete or entirely free from error. Since its
publication, therefore, effort has been made to discover
omissions and mistakes, in the hope that some time in the
future we can make any corrections that may be found
necessary. "We wish at present to call attention to the
following list of the more important errors and omis-
sions thus far discovered.

(1) The town boundary between Mt. Desert and Tremont
in the territory lying between Somes Sound and Great
Pond should begin on the eastern shore of Great Pond at
the point shown on the map, and should run in a straight
line in a southeasterly direction to a point on the shore
of Valley Cove nearly opposite the word "Eagle" on the
map. This shows the true boundary some distance to the
north of the boundary shown on the map.

(2) At the Quarries on the western shore of Somes
Sound a post-office should be added, " Halls Quarry P. 0. "

(3) The name Western Hio, north of Bass Harbor, it
seems, should be applied to the southern end of Norwood
Ridge. Where the name now stands on the map. Burnt
Mt. should be substituted.

(4) Black Point on Great Cranberry Isle may have to be
changed to Flaggs Point.

(5) The small brook at Bar Harbor, flowing into the

1 It may be interesting to note the use of the word " heath " on the Island.
It is used to denote a large unwooded bog or swamp, usually a sphagnum
bog, very wet, and exceedingly difficult to cross. Many of these heaths
contain small ponds or spring holes, and in the wetter parts are floating bogs
more or less dangerous and treacherous to any one venturing upon them.

32 INTRODUCTION.

cove opposite the southwestern end of Bar Island, is
known as Eddys Brook.

(6) The point next northwest of Cape Levi is known as
Parker Point.

(7) The brook rising east of Town Hill, and flowing
into the South Branch of Northeast Creek is known as
Aunt Betsys Brook.

(8) The brook flowing westward into Clark Cove is
known as Meadow Brook.

(9) The marsh by the Salt Pond on Thomas Bay is
known as Jones Marsh.

(10) Denning Walk at the Quarries on the western
shore of Somes Sound lies farther to the eastward, between
the road and the shore, and the position of the name
should be changed accordingly.

(11) The course of Sunken Heath Brook is shown incor-
rectly between Sunken Heath and the road. It should flow
directly south from the Heath to the road, not as shown
on the map. The remainder of its course, however, is
correctly shown.

(12) The name Saul Cliff, on the shore south of Bar
Harbor, should be Sols Cliff.

We should be very glad to receive from any one other
information that will serve to make the map more perfect
and useful to those interested in the Island.

III. Nomenclature op the Catalogue.

As was stated in the Preface, it seems well to the
authors to state more at length the reasons why they
think it advisable to follow as a standard for this cata-
logue the nomenclature of the sixth edition of Gray's
Manual (so far as it covers the ground), rather than that

INTRODUCTION. 33

of the so called Rochester and Madison Codes, adopted
in 1892 and 1898 by the Botanical Club of the American
Association for the Advancement of Science.

At the outset it should again be stated that we believe
the nomenclature and arrangement of a local Flora should
follow that of some well known or authoritative work or
system. If, on the one hand, the system followed is not
well known, the catalogue will not be of much use to many
for whom it was intended ; if, on the other hand, the sys-
tem does not emanate from some respected authority, it is
folly to attempt to force it on any intelligent person.
The main question for an author or compiler to consider
clearly seems to be, What standard can be followed that
will be most intelligible and most useful to those for
whom it is intended, — to the plant lover of slight botan-
ical knowledge, as well as to the professional botanist of
thorough training? In making the decision the author
need not necessarily follow his own personal inclinations,
— in fact it is not right or expedient for him to do so if
clearness and usefulness must be sacrificed thereby, — his
duty is to help, not to hinder his public, and to yield his
personal preference for the good of others. If he wishes
to express his personal opinions and convictions he can
do this at pleasure through many appropriate channels;
he may speak thus whenever he will. The public cares
very little for the personal convictions and peculiar the-
ories of its servants if unintelligible and practically
useless. It does demand, however, that the servant
should do his duty, and serve the good of the master, not
any private or selfish purpose of his own. It is hard to
see how the contrary can be maintained.

It being granted, therefore, that we must not necessarily
set out our own personal opinions, but must make our

34 INTRODUCTION.

catalogue useful and intelligible, in duty to all who con-
sult it, we had to consider what well recognized standard
we could follow. The choice appeared to lie between
Gray's Manual, mainly the work of our greatest botanist,
and the principles now embodied in their strictest form in
the Rochester Code and extended in the Madison Code.
The chief of these principles one of us had studied for
years, and the other had put to practical use, as a test of
their real value. Moreover, we both felt that the priority
of the specific name should on sound analogies be main-
tained, in opposition to the well known rule of Dr. Gray
that the first specific name in the right genus should
prevail. Nevertheless, as a result of our deliberation we
have decided that a local Flora at this time without ques-
tion must follow Gray's Manual, whether or not its authors
agree entirely with the nomenclature of that work; that
to follow strictly the system dictated by the Rochester
Code is utterly impracticable and unwise, for it is neither
consistent in theory nor sound in practice. This conclu-
sion has been reached after long judicial consideration of
the arguments for and against the system of the Rochester
Code, whether practical or theoretical in nature, and with
an earnest desire to approve any really beneficial altera-
tions in the commonly accepted system of botanical nomen-
clature. We regret, therefore, that the Code, as a whole,
must be condemned for the evil that is in it, and that the
good it contains cannot be utilized in its present form.
As it stands, it seems the work of botanists whose vision
is bounded by the book-shelves of the library and by the
herbarium walls rather than of botanists possessing that
added knowledge and grasp of affairs that is so indis-
pensable to a correct solution of difficulties in such a
practical matter as that of botanical nomenclature.

INTRODUCTION. 35

The mental attitude of the supporters of the Rochester
Code seems at first somewhat difficult to explain. If we
abandon for a theory of our own well known and estab-
lished principles sanctioned by the greatest authorities
and the soundest analogies, we must justify our action.
We have not yet seen any such justification of this Code.
It seems that the explanation must lie in the fact that its
supporters cannot appreciate that they have a case to
prove, and that the burden of proof rests on them alone.
If they act in contravention of fundamental principles
and of the authority and consensus of the greatest bota-
nists, they must prove to the satisfaction of an intelligent
man that they are acting rightly. Even granting that
the Code is proved of utility, the rule still applies to every
change they seek to make. In fact, however, they assume
the contrary, and are open to the gravest criticism for
constantly leaning in favor of change, and of blindly
following what is apparently their guiding principle, —
Quieta movere. Where doubt exists, the old and accepted
name or identification should be preferred in every case
to the new and unproved. We know no reason why
botanists should be exempt from following such funda-
mental rules. If the Code permits the contrary practice,
as its advocates take for granted, it cannot be followed.

Thus it appears to be most necessary for these botanists
to prove that their system secures advantages that the old
system does not possess. If, on the one hand, they claim
that it is more sound in theory, it may be said that prac-
tical relief, not theoretical relief, is needed. Moreover,
their theory is inconsistent within itself, being founded
partly on absolute dedication of a name to the public,
and partly on the absolute inability of the public to do
what it will with its own. Thus we are not only told that

36 INTRODUCTION.

an author cannot change a name once published, because it
has passed from his control ; but we are also no less gravely
told that a name once published can never be changed by
the public either by usage or in any other manner, — an
inconsistency that it is hard to explain in any reasonable
manner. If, on the other hand, they claim that in practice
strict adherence to priority does away with the uncertain-
ties of individual judgment, and secures absolute certainty
in nomenclature for past, present, and future, this assertion
may be fairly denied, at least so far as the past is con-
cerned. Any one who has followed the many differences
in judgment, and the disagreements as to actual priority,
ean easily realize that it is a matter requiring much
acute and long continued investigation to fix absolutely
the historical priority and identity of names. This fact
should have deterred many botanists from rushing into
print with their new-old names, like children eager to
display a new toy, only to discover later that they had
been too hasty, and had merely added to the ever increas-
ing host of synonyms. Furthermore, how can it be known
that this system will be permanent ? Its advocates claim
that they not only can violate other theories, and coin
artificial rules to secure any desired result, but can as
readily disregard and reject many principles of a funda-
mental nature that are well recognized by practical men
of affairs, whether scientists or laymen, and have been so
recognized and approved by the greatest botanists. If
these can be set aside by any one with a theory of his own,
what security have we that the Rochester Code, with all
its inconsistencies and objectionable features, will not be
set aside in a year or two in favor of some radically
different theory ? This is a very serious matter. Through
short-sightedness the fatal error has been made of disre-

INTRODUCTION. 37

garding the permanent and actual for the transient and
theoretical. If, therefore, we approve sucli a course of
action, we in reality cut the solid ground from beneath
our feet. Our view of this matter is fully confirmed by
the dissatisfaction of many of our botanists, and their
freely expressed intention to use the Rochester Code only
until they find something better. Indeed, even one of the
leaders among the faithful of late refuses to follow the
Code in regard to the starting point for genera.

Of course the greatest fault to be found with the Code
arises from the wanton exercise of ex post facto legislation
to accomplish the ends of its advocates. Were the ques-
tion of botanical nomenclature in the main a matter of
interest to scientists only, as until very recently orni-
thological nomenclature has been, this legislation would
do no great harm if generally assented to; but to employ
it in a science like that of botany, where generic and
specific names have become, as it were, subjects of prop-
erty rights, is unwarranted and short-sighted in the
extreme. One result has been, that if we follow the Code
we may have a botanical name and a horticultural name
for the same plant, both correct, but one to be used at
one time, one at another, — a somewhat humiliating state
of affairs when it is borne in mind what efforts have been
made to make horticulturists use the generally accepted
botanical names. The worst of the whole matter is that
the horticulturists are dealing sensibly with facts as
they find them, while the botanists are striving with
theories to annihilate facts. It is hard enough, as any-
body of experience knows, to make a horticulturist adopt
a change in nomenclature made necessary for scientific
reasons ; but how impossible it would be to force upon him
a change made merely to carry out a theory or a system

38 INTRODUCTION.

of questionable expediency ! What can be gained by inten-
sifying this distinction between botanical and horticultural
nomenclature, especially now that the horticulturists have
refused to follow the Rochester Code on the practical
ground that it does not recognize the well established
principles of property rights, custom, usage, and the salu-
tary maxim, Quieta non 7novere ?

Any system of nomenclature, especially one creating
confusion by asserting new and unusual theories, should
come before the public as a result of mature, impartial,
long considered adjudication. While we are perfectly
willing to consider the Rochester Code as the expression
of the personal opinion and preference of its advocates,
we find ourselves unable to admit that it has any other
authority to sustain it. It is true that it was fathered
by the vote of the Botanical Section of the A. A. A. S. at
the Rochester Meeting in 1892, but the published record
of the proceedings shows clearly that the committee
appointed could not have given the subject proper con-
sideration and adjudication. In fact, apparently less
than one day was sufficient for this committee to pass
on a subject of so much practical importance, and then
in a manner that involved the rejection of fundamental
principles confirmed and supported for years by the
authority of the greatest botanists. Further comment is
unnecessary.

It has, moreover, been asked, with some pertinence,
What authority had the Rochester Meeting to bind Amer-
ican botanists by any such code of nomenclature as a
majority of the members present might see fit to adopt ?
It is perfectly clear that its sole authority lay in the
united dictation of the various botanists present. We
confess we find it somewhat amusing, — after all the

INTRODUCTION. 39

protest against one-man authority, no matter how great
that man might be, and after all the laudation of the democ-
racy of the botanists, — that the real democracy, in which
every botanist has a vote, should now be dictated to by a
comparatively few botanists of various degrees of repute.
History testifies that power and dictation are fully as
sweet to thirty tyrants as to one! The matter practi-
cally wears this aspect in our opinion, since we have been
unable to find more than passive approval of the Code
outside of a comparatively small circle of botanists, and in
many cases have found active disapproval or a decided
disclaimer of any sympathy with the Code where we
hardly expected it. We sincerely hope that botanists
in other countries will not be deceived into thinking that
this school of nomenclature includes the American bota-
nists, for it includes only a part, even if it is the part that
makes most of the noise !

Another evil produced by the adoption of this Code is
the great prominence given to the botanical name-monger,
a term which we use for convenience to denote those
botanists who devote much of their time to changing
about names of plants for no scientific reason, but merely
to fit them to a code. To the binomial thus manufactured
they add their names, and stand apparently on a par with
botanists whose names attached as authors stand for true
scientific achievement. The addition in parentheses of
the name of the original author of the specific name does
not help the matter much in such cases, for it does not
explain the binomial. There are, moreover, no indica-
tions at present that there is likely to be such a consensus
of agreement in the names of plants as might enable us
to omit the name of the author altogether. Thanks to
the provincial-mindedness of the so-called reformers, we

40 INTRODUCTION.

are farther from this agreement than we were ten years
ago. All this is a natural result of the unjustifiable
attempt to apply rules too strictly in many respects to
the past, over which no botanist can expect to legislate
if he knows anything of conditions outside of his her-
barium walls. If the supporters of the Rochester Code
think they have a right to upset important results of
nomenclature evolution for nearly a century and a half
merely to help out their theories, they must be veritable
Rip Van Winkles, just awakened from a comfortable
nap of years.

We sincerely regret that so many of our younger bota-
nists have been led astray by this ignis fatuus of theory,
and so blinded to the clear fixed lights of sound judgment
and of practice. No code of botanical nomenclature can
hope to accomplish good results that does not meet the
needs of the time; this the Rochester Code does not do.
We cannot afford to begin over again, or submit to tempo-
rary confusion for the sake of any theory, or for the sake
of a future peace that may never come.

In our consideration of this matter we have pointed out
a few reasons why we could not follow the Rochester
Code. It would be easy to be more specific, and give
others, did we feel that it were incumbent on us to do so.
We see no reason, however, why objections should be set
out by any one dissatisfied with the Code, when the sup-
porters have thus far been unable to prove that it has any
right to exist beyond their own will. Let them attempt
to prove their case, and their argument will be impar-
tially heard by all interested in this matter of botanical
nomenclature. At present they are in default.

In conclusion, we wish to add a few words in explana-
tion of the arrangement adopted in this catalogue. The

INTRODUCTION. 41

arrangement of Engler and Prantl's " Natiirlichen Pflan-
zenfamilien," adopted as a standard at the Madison Meet-
ing of the Botanical Section of the A. A. A. S., seems to us
not sufficiently well known, accessible, and understood in
this country to make it advisable to adopt it at present in
a local Flora, or in a mere list of plants. It has been
adopted in Algse alone in this Catalogue. As our decision
in regard to the standard of nomenclature obliged us to
follow Gray's Manual, it seemed well to us to follow its
arrangement also, so far as its scope allowed, and beyond
that to follow the manuals and other works already
mentioned in the Preface.

AN OUTLINE

OF THE

GEOLOGY OF MOUNT DESERT.

By WILLIAM MORRIS DAVIS.

'T^HE mountain range of Mount Desert includes the
■*• highest of a number of mountainous hills that rise
over the rolling lowland of southern Maine. The lowland
has been slightly inclined to the south, so that a part of
its original area is depressed under the sea, to make the
platform of the Gulf of Maine ; while its northern exten-
sion slowly ascends inland until it deserves the name of
a plateau in the northern part of the State. The tilted
lowland is roughened by the excavation of numerous
valleys ; and since these were formed the coastal region
has been slightly lowered, carrying the sliore line farther
inland than before, changing many a valley into a long
arm of the sea, and isolating many a hill top as an out-
lying island. Associated with this later change of level,
and during a time of colder climate, there was an invasion
of the region from the north by a sheet of ice, such as
that which still maintains possession of Greenland, The"
slow but rough-shod march of this cold conqueror stripped
the loose soil from the land, wore down the sharper
ledges of the hills, deepened many of the valleys, and
dragged along the rubbish thus gained farther and farther
southward. When the invader was driven away by the
return of a milder climate, the rubbish or "drift" was
irregularly disposed over the uneven lowlands, thereby

44 AN OUTLINE OF THE

greatly embarrassing the flow of the streams that again
took possession of the comitrj, frequently turning them
aside from their former courses, and often holding them
back to form lakes.

The rolling lowland over which the mountainous hills
rise is not, like the coastal lowlands of our southern
States, a former sea-bottom recently emerged, and still
for the most part as smooth as it was when under water.
The lowland is low, not because the country was never
built up to a greater height, but in spite of having been
long ago strongly uplifted in disorderly form. The low-
land is low because the whole region has been worn down
from its high estate by long continued denudation. It
lias slowly wasted away under the ceaseless attack of the
atmosphere. Its relief is now generally of moderate meas-
ure because, before the lowland was tilted into its present
southward inclination, it had been worn down nearly to the
level of the sea of that time, and only the more resistant
rock structures then still withstood denudation success-
fully enough to hold up their heads as residual moun-
tains and hills. There is every reason to believe that even
the residual mountains were once more lofty than they
are now ; that the whole region was once deformed and
upheaved into a rugged highland ; but these ancient fea-
tures have been subdued and almost lost in the denudation
of advancing old age. The existing mountains must there-
fore be i-egarded not so much as points of excessive upheaval,
but as points where the wasting of the land has been
retarded. The mountain range of Mount Desert is one
of the most stubborn survivors ot the ancient highland.
The beauty of the Island as seen from the sea, unpar-
alleled along our whole Atlantic coast, is owing to its
persistent retention of a good share of the height which
this whole region once had, but which its surroundings
have lost.

GEOLOGY OF MOUNT DESERT. 45

Although the granitic rocks of the Mount Desert range,
and of other mountains in southern Maine, are now cold
and quiet in their old age, they were once hot and ener-
getic, pressing their way upward as a vast molten mass
towards, and perliaps to what was then the surface of the
ancient land. Their upheaval and outburst may have
contributed largely to the altitude of the former surface ;
but of this we know little. Other intrusions of melted
rocks occurred on large or small scales, and on dates
earlier and later than that of the mountain granite ; but
their heat has all long since died out. The great denuda-
tion by which the present lowland has been carved in
the ancient highlands is later than the latest of the
igneous outbursts ; and the glaciation by which the finish-
ing touches have been given to the country is a thing of
yesterday.

When a brief summary of geological history is thus
presented, the reader, if he is not versed in the interpre-
tation of evidence presented in the language of the rocks,
is likely to regard the whole subject as something of a
mystery. He may even imagine that the facts and argu-
ments to which the geologist appeals are obscure and
abstruse. This is not the case. Common eyes and com-
mon sense may perceive all the essential points in the
evidence leading to the conclusions just stated. If the
reader will walk patiently over the island, look closely,
and think clearly, the whole argument may be appre-
hended ; and when his attention is taken less by the con-
clusions to which the evidence leads than by the evidence
which leads to the conclusions, the mystery vanishes ;
the essential simplicity of logical scientific investigation
takes its place, and the face of nature gains a frank and
sincere expression that it has to him never worn before.
Let xis use the foregoing paragraphs in the nature of a
table of contents, and now turn more particularly to see

46 AN OUTLINE OF THE

the facts by which the geological history of Mount Desert
may be interpreted.

Seldom are geological facts more plainly presented.
Seldom have pleasanter days been spent than those
recalled while writing out this sketch. We have coasted
in good company and under good pilotage along the rocky
shore, landing for our geological discoveries even as old
Champlain may have landed for his geography, and return-
ing to our vessel at night. We have clambered up pathless
glens to rugged summits ; and if we carried rations for
only half a day, we felt nevertheless the spirit of explorers
in unknown lands, and our adventures were recounted
around camp-fires in the evening. Our vacations are
shorter now than then, and while recalling them in this
writing we must leave to others the pleasures on sea and
shore once our own.

The Granite Belt.

The granitic mass of Green Mountain, and of its domi-
nant fellows east and west, and of a belt of adjacent
lowland across the Island about parallel to the range,
serves as a natural beginning in our study, and from the
date of the origin of the granite we may go backwards
and forwards in time until the whole sequence of events
discoverable within our borders is determined. The rocks
of the mountain belt, wherever examined on summits or
flanks, have a remarkably uniform crystalline texture,
consisting of an intimate mixture of quartz, feldspar, and
hornblende, to which the name of hornblendic granite is
given. The constituent minerals may be easily recognized
by the unaided eye : the quartz being translucent and
glassy, with uneven surface ; the feldspar, gray or pink,
with even cleavage surfaces ; the hornblende, black, and
in smaller particles than the other minerals. The massive
structure of this rock, in so strong a contrast to the bedded

GEOLOGY OP MOUNT DESERT. 47

arrangement of stratified or water-deposited rocks, indi-
cates that its materials were not brought here in fine
particles and in succession, and laid down in beds one after ^J
another ; but that the whole mass took its place essentially
at once, and that its structure was gained by a single
process, in operation practically at one time in all its parts.
Slow crystallization by cooling from fusion is the most
plausible explanation of such a result ; and this is borne
out by an examination of the structure of modern lavas,
which solidify after flowing in molten streams from visible
vents ; and by analogy with the crystallization of mineral
substances artificially melted and allowed to cool. The
granite is therefore regarded as an igneous rock ; a rock
which has been at one time molten from heat.

The granite occupies a belt across the Island, enclosed
on the north and south by rocks of other kinds. Isolated
areas of granite are found eastward from Bass Harbor
Head, and at some other points. Descend the mountain
slopes to the lower ground, and although much of the
surface is covered with drift, the observer will sooner or
later meet with rocks of quite different appearance. At
first, these are seen as isolated angular fragments of
various kinds and sizes included in the granite ; the frag-
ments then become more frequent, as in the wonderful
display at Hunters Beach Head ; further on, the granite
is found penetrating long, relatively narrow crevices in
the other rocks, as on Sutton Island ; and at last the
granite ceases entirely, and the surface is occupied, when-
ever its rocky floor can be seen, only by rocks like those
first seen as fragments enclosed in the granite. Near the
margin of its area, the granite is finer textured than
further within its mass. This indicates that, when it
cooled from fusion, the margin cooled faster than the
interior ; for it is the habit of rocks when crystallizing
from a melted state to develop only smaller crystals and

48 AN OUTLINE OF THE

finer texture near their boundaries, where they are chilled
and solidified quickly ; while larger crystals and coarser
texture are produced within the mass, where the cooling
is more gradual. Even a broken bar of pig iron illus-
trates a variation from fine to coarse texture in passing
from its surface to its interior.

The fine texture of the margin of the granite, the inclu-
sion of numerous angular fragments of the country rocks
along the borders of the granite belt, and the penetration
of the country rocks by narrowing granitic arms, or dikes,
demonstrate that the granite is a later comer than the
other rocks, and that it moved from some former position
to its present position while molten, breaking its way into
the solid, rocky crust in its escape from some excessive
pressures that forced it to move ; until at last, when the
impelling pressures were satisfied, it came to a halt, and
slowly froze into a rigid mass, holding close in its grasp
thousands of fragments gathered from the enclosing walls.
The only imaginable source of supply for such a mass of
molten rock is in the earth's interior; and although no one
can well account for the forces by which the granite was
squeezed outward from its former position, no one can
justly doubt the reality of its out-thrust. The granitic belt
is indeed nothing more than a great irregular ragged dike,
pushed upward through the ancient rocky crust of the
earth. Many such intrusive masses are known elsewhere
in New England, and in other parts of the world. The
Blue Hills near Boston are largely composed of intrusive
rocks, amid surroundings much like those of the Mount
Desert range ; the rocky dome of Cape Ann is of similar
nature.

The granitic outburst is the greatest event in the history
of Mount Desert. It is of colossal magnitude. The energy
of its intrusion cannot be conceived. Not that the intru-
sion was suddenly accomplished, but that it was effected

GEOLOGY OF MOUNT DESERT. 49

against enormous resistances, and that it involved the
movement of gigantic masses. The granitic belt is at least
twelve miles long and seven wide. No one can give any
measure of the former greater height to which it ascended ;
and certainly he would be a daring geologist who would set
a limit to the unsounded depths from which it rose. The
uprising may have required many historic ages ; it may
have been relatively rapid ; but that it was progressive, and
not instantaneous, is easily seen by a closer examination of
the minor events recorded along its margins.

Much of the lowland is covered by glacial drift and by
postglacial marine clays ; but along the seashore the rocks
are swept clean, and their surface is continuously visible.
The bare ledges and cliffs of Hunters Beach Head, as well
as of many other similar points on the southern coast,
afford wonderfully clear illustrations of the processes of the
granitic intrusion. Here we may follow the granite wedg-
ing its way into narrowing cracks among the older rocks.
Great fragments of older rocks of various kinds are caught
off in the granite and mixed together in confusion. Some-
times a block is found to be divided by granite-filled fis-
sures, and yet its several parts may still lie so close to one
another that they can be matched with certainty ; thus
proving that after the block was broken from the wall of
the vast fissure it was further fractured, and the minor
cracks thus opened were filled by the mobile granite. This
may be seen on the eastern side of the Narrows of Somes
Sound, and along the shore ledges to Smallidge Point south
of Wasgatt Cove. The granite rock, now so rigid, then so
liquid, or at least then yielding so perfectly under the
pressures that were exerted on it, entered into the nar-
rowest little crevices, following them down to hair-like
fineness. Nowhere in the world may the traveller find
better, illustrations of the manifold processes of deep-seated

intrusions than are here exhibited on the wave-swept ledges

4

50 AN OUTLINE OF THE

of the southern coast, eastward from Somes Sound. They
are fully equal to the wonderful display of successive in-
trusions of igneous rocks along the Massachusetts coast
in Swampscott, Marblehead, and Beverly.

When the observer first examines the varied features of
this rocky coast, his attention will be limited to the surface
of the rocks as now exposed. But the structural problem
of the Island is not simply a problem of surfaces in two
dimensions. It is a problem of solids in three dimensions ;
and the third dimension of heiglit or depth must be inferred
from what can be seen on the length and breadth of the
surface. It will be plain, when we come to consider the
denudation which the island has suffered, that the present
surface has no particular relation to the whole mass of
ancient country rocks and intrusive granite with which we
are now concerned. The present surface merely marks
the stage of denudation reached at this hour of geological
time ; the surface at earlier hours intersected the mass at
a greater altitude ; in later hours the intersection will be
carried lower down into the mass. The present surface
may therefore be taken, not as belonging only to the present
time, but as a fair sample of what would be exhibited on
any nearly horizontal section across the mass, not very far
above or below what is now seen.

We must therefore conceive of the great granite dike
not only as limited by horizontal marginal lines, but as
enclosed by ragged walls ; and this structure must be men-
tally restored upward into what is now the open air, as well
as deeply downward into the solid earth. The original
walls undoubtedly termiuated in both directions ; but no
one shall say how far they extended at the time when
the granite had just made its way upwards from the deep
interior of the earth and frozen stiff in its new position.
The greater part of the intrusion is pure unmixed granite ;
but far up and down the walls there must have been a con-

GEOLOGY OF MOUNT DESERT. 51

fusion of included fragments broken from the country rock,
and a great branch-work of lateral granitic dikes penetrat-
ing the sides of the vast fissure. We shall later return to
consider the denudation of the ancient mass into its pres-
ent form ; but before that several facts of even more ancient
date than the granite intrusion must be examined.

The Pre-Granitic Rocks.

Even the casual observer can hardly fail to detect a
marked variety in the nature of the rock fragments
included in the granite along the southern and western
coast. Every one of these rocks is older than the granite.
Many of them are distinctly unlike in composition and tex-
ture, and probably also in age. Some are therefore older
than the granite by longer ages than the others. Their
sequence must be deciphered as far as possible.*

The most manifest varieties of these older rocks may bo
briefly described. On the western and northwestern coast,
and on some of the adjacent islands, as Bartlett and Hard-
wood Islands, there is an area of wrinkled greenish schists,
in somewhat disorderly attitude, associated with quartzitic
layers. Their southernmost occurrence is at Dix Point,
and northernmost at Thomas Island. The schists trend
northwest, north, and northeast, dipping to the eastward,
or towards the granite, at various angles. Their thickness
is estimated as two thousand feet at least. These schists
are cut by the granite at several points, and hence belong
in the pre -granitic series ; but as they are not found in con-
tact with the other marginal rocks, it is only on account of
their gnarled and ancient appearance that they are placed
at the foundation of the history of the Island. They seem

* A number of statements in this section, and in the section on the
glacial invasion, are taken from an essay by Prof. N. S. Shaler, on the Ge-
ology of the Island of Mount Desert, in the Eighth Annual Report of the
Director of the U. S. Geological Survey, Washington, 1889.

52 AN OUTLINE OF THE

to have been originally stratified sedimentar}^ deposits ; but
their texture has become crystalline by long continued
change, and hence they are to be regarded as extremely
ancient. It is probable that a search on the neighboring
mainland will enable us to define more precisely the rela-
tive age of the schists by means of their contact with the
other old rocks ; and when this is done, we may expect to
find proof, not only that the schists are the oldest of the
series, but that after the deposition of their sediments they
were buried deeply enough for metamorphism into their
present crystalline structure, and then greatly denuded
before any other rocks were formed in this region. They
will then be seen to be older than the other rocks by a
great interval of time. The rocks of Schooner Head and
of a limited stretch of the eastern coast may perhaps be
classed with the greenish schists of Bartlett Island ; but
their age is not well determined.

On the southern and northeastern sides of the Island,
and on some of the adjacent smaller islands, as Bar Island,
the Porcupines, and Sutton Island, there are many ex-
posures of a series of bedded rocks, partly slates, partly
sandstones and flagstones. These are manifestly sedi-
mentary deposits in ancient seas. They are of firm
texture as a rule, although some of the layers are weak
enough to undermine the overlying beds and form dis-
tinct ledges, as near Bar Harbor landing. Sometimes
there are fine pebbly layers, with grains of white quartz,
as on the shore near Northeast Harbor. The greater
part of this series is well indurated ; but otherwise it has
suffered little structural change since its deposition. In-
deed, if any fossils had originally existed in the beds, they
should be still observable, but none have yet been found.
The strata generally dip away from the granitic belt ; and
on the Cranberry Isles their inclination is nearly vertical.
The granite cuts them in various places, and frequently

GEOLOGY OF MOUNT DESERT. 53

includes their fragments along the southern coast ; hence,
like the greenish schists, they belong to the pre-granitic
series, hut at present it is only by inference that they are
regarded as younger than the schists, as already explained.
There may well be a considerable diversity of age among
these bedded rocks, yet to be discovered.

The northern shore by the Ovens, the southwestern
extension of the Island, and several of the smaller islands
to the southeast, contain many exposures of old volcanic
rocks, known as felsites. They are of crystalline texture,
but much finer than the granite of the central belt, and
are often arranged, like modern lavas, in sheets or flows
parallel with the beds of the adjacent stratified sedimen-
tary rocks. They frequently possess a porphyritic structure ;
that is, small crystals of feldspar are disseminated through
the mass. Again, they have a banded structure, due to
flowing while molten ; and they are often broken or brec-
ciated, as if eruptive movement had continued after a part
of the mass had become solid. This structure is exhibited
on the eastern shore of Bass Harbor. Associated with the
denser masses are large fragmental and ash-like deposits,
as if formed by explosive eruptions from some neighboring
vent not now identifiable. Occasionally, dikes of felsite
are found cutting through the rocks of the bedded series.
Like the bedded rocks, they are cut by the granites, as
may be well seen east of Bass Harbor. Considering all
these features, it may be concluded that the felsites mark
a time of volcanic activity contemporaneous with a part of
the period during which the sedimentary series was formed.
The sandy or muddy sea bottom of that era must have
received, from time to time, flows of lava and showers
of ashes ; volcanic cones may have been built somewhere
in the neighborhood, although not a trace of tliem now
remains. While in process of accumulation, the bedded
rocks and the lava flows must have lain almost horizontal ;

54 AN OUTLINE OF THE

but they are now steeply tilted to the south and deeply
worn away, so that the present surface in the Cranberry
Isles reveals what would have been originally almost a
vertical cross-section of the mass. Minute study may
discover interesting details of this chapter of the Island's
history ; but the record is fragmentary by reason of the
denudation that has swept much of the structure away,
and the submergence which has sunk a good part of the
remainder beneath the sea; and the remnant standing
above the present sea level is blurred over by the sheet of
glacial drift. Yet it is by putting together such imperfect
records as this that much of the geological history of the
world has been made out. A close study of the ancient
volcanic area in the southern part of Mount Desert would
doubtless well repay any one who can undertake it.

Along the southern coast, east of Somes Sound, and at
various points on the western coast near Bai'tlett Island
Narrows, there is a dark-colored crystalline igneous rock,
known as diorite. It consists chiefly of hornblende and
a triclinic feldspar : the fine parallel lines on the cleavage
faces of the feldspar resulting from the twinning of crys-
tals can be easily seen with a hand lens, thus distinguishing
the triclinic feldspar of the diorite from the orthoclase
feldspar of the granite. The diorite is shown to be an
igneous rock by its structure, and by its intrusive relations
with other rocks, here and elsewhere. It cuts the lower
members of the stratified rocks near Northeast Harbor,
and it is frequently cut by or included in the granite ;
hence its age is intermediate between the ages of these
two ; but its relations to the volcanic felsites are not
yet surely determined. The felsites were contemporary
superficial extrusions upon certain members of the bedded
rocks, while the diorite presents only the features of a
deep intrusion, as if thrust in among the bedded rocks
after th^j had accumulated in much greater mass than

GEOLOGY OF MOUNT DESERT. 55

they possessed when the felsites overflowed. It is there-
fore probable that the diorite is younger than the felsite.
At certain points in Northwest Cove, on the western coast,
the diorite is of two liinds ; the finer textured masses
being cut by those of coarser texture, and thus indicating
two periods of intrusion of this rock.

This general survey of the older rocks may now be
summarized. The metamorphic schists seem to be the
most ancient, and it is probable that a long unrecorded
time elapsed after their deposition before the next series
was formed. Then comes a variety of unaltered sedimen-
tary rocks, to whose accumulation a long time must have
been devoted, and whose history was diversified by much
volcanic action. Tiie geological date of these rocks can-
not be affirmed ; but, judging by analogy with similar rocks
along the New England coast, it was probably Cambrian,
a very ancient time division of geological history. How
long the conditions of deposition prevailed, and how great
a thickness of deposits was formed before their subsequent
destruction began, no one can now learn ; but we shall see
reason to believe that the existing amount of bedded rocks
is probably only a small share of what once existed in this
region. At some part of the time, when the accumulation
of the bedded series had reached a considerable volume
above the present surface, the intrusions of diorite took
place within the mass ; and again, at a still later time,
came the great granitic intrusion ; thus leading us to
the undated epoch with which this account of the rocks
began.

The Post-Granitic Rocks.

The only indurated rocks now recognized as of later
date than the granite are the trap dikes, by which all the
other rocks of the Island are traversed at one place or

56 AN OUTLINE OF THE

another. These dikes are commonly from two to ten feet
wide, standing nearly vertical, trending somewhat east of
north with rather direct courses. They are found on low-
land and highland, from water's edge to mountain top.
They nowhere exhibit the smallest indication of overflow ;
even over the summit of Green Mountain they are as dense
and as well contained within their walls as at sea level.
Hence, when they were intruded, the rocky mass must
have risen above the mountain tops of to-day. It is pos-
sible that their lavas may have reached the surface of
their time, and maj"- have there overflowed, much in the
same way as the felsites ovei'flowed on a lower surface
long before ; but we have no evidence of such surface
action. The dikes, as now revealed, are deep structures,
and with the diorites and granites proclaim the greater
mass that the rocks once possessed, and the wasting that
the region has since then suffered.

The Great Denudation.

If the greenish schists are older than the bedded rocks,
as may be supposed, it is eminently possible that the
unrecorded time between the deposition of the two series
witnessed a denudation as great as that which we have
now to consider ; but our attention cannot be well directed
to that long lost chapter of the Island's history. The
chapter is at present only a matter of fair inference, and
it never can be fully reconstructed. It is like those many
lapsed periods of ancient human history, unmarked by
recoi'ds of great battles or by the dethronement of kings,
over which our imagination passes so lightly, and with so
little appreciation of all that they contained. But with
the later denudation, by which the present form of the
Island has been fashioned, we have much to do. It calls
for study as attentive as that by which the making of the
rocks is discovered. A full understanding of the geological

GEOLOGY OF MOUNT DESERT. 57

history of a region requires an examination of the records
of denudation, as well as of those of accumulation. It is
likely that Nature gave quite as much time to wearing
down as to building up the Island ; and we may well follow
her example in the division of our sections.

The reasons for believing that the Island and the adjacent
mainland have lost much of the rock mass that once existed
above their present surface may be briefly stated. We first
notice that, if the tilted beds of the stratified and volcanic
series were again extended upwards into the air from their
present denuded edges, a great increase would be given to
the altitude of the surface. This is not merely a local mat-
ter. The same conclusion is reached all along the New
England coast, and far inland. The rocks of the whole
region are greatly disordered, much as rocks are in lofty
mountains, and the edges of the strata as now revealed
are by no means the original edges. How far they once
extended upwards cannot be stated ; but the distance
should be estimated in thousands of feet rather than in
hundreds.

The evidence thus derived from the attitude of the
bedded rocks is confirmed by the features of the intrusive
rocks, — the diorites, the granite, and the trap dikes. None
of these exhibit any trace of surface extrusion, such as is
so plainly manifested in the more ancient felsites. Hence
we must suppose that, since the felsites were extruded, a
great accumulation of superincumbent materials was loaded
upon the region, and that it was upwards into this heavy
accumulation that the intrusive rocks were thrust. It is
quite probable that during the time of accumulation and
intrusion the whole region stood lower than it now does,
even so low that its surface then was near or below sea
level. As long as this low stand was maintained, further
accumulation would be natural enough, and denudation
would be postponed. No limits of quantity or time can

58 AN OUTLINE OF THE

now be placed to the era of accumulation ; but it was closed
at last by elevation, and with that change the present chap-
ter in the history of the Island was opened. Judging by
the tilted and twisted attitude of the bedded rocks, both on
the Island and elsewhere in New England, it is probable
that the time of elevation was a time of mountain growth,
when the rocks were deformed as well as uplifted. The
coast line must then have been pushed farther out to sea,
nearer to the margin of our continental shelf. The moun-
tains may have risen as high as the Alps ; they may have
borne glaciers on their upper slopes ; great rivers may have
drained their valleys. The rocks may have suffered moun-
tainous deformation at more than one period, writhing
under successive applications of crushing forces, after the
fasliion of mountains of more recent construction, whose
building is better known. During, between, and after the
periods of crushing, the forces of the atmosphere maintained
their ceaseless attack on the exposed surface ; and their
final success in reducing tlie ancient mountains so nearly
to a lowland reminds one that the persevering tortoise over-
took the spasmodic hare.

The lack of definiteness by which this section is charac-
terized may make appreciation of it more difficult than
of one which, like the section on the intrusion of the
granite, is accompanied by specific illustration at every
step. All the more patiently, therefore, should the reader
pass in review the scenes of existing mountains, having
faith that where mountain roots are now exposed, there
mountain heads once arose. Just as he might recall, while
resting on the prostrate trunk of an old moss-covered
forest tree the early sprouting of its seed, its adolescent
growth above the lowlier bushes, its mature attainment of
forest height, its fall and decay in old age : so he must
picture the young mountains once rising along what is now
the New Entrland coast ; he must see them grow once and

GEOLOGY OF MOUNT DESERT. 59

again, rearing their crests to the height of the clouds ; he
must watch them slowly, slowly wearing away till only
their roots remain. Even as we are told that in man
death begins with birth, so with the mountains : their
wasting begins as they first rise above the sea, and, how-
ever lofty they grow, they must in the end be prostrated.
Energetic mountains of great altitude, so young that they
are still high and growing, are not the only kind of moun-
tains that cross tlie face of the earth. Many a mountain
range, once lofty, has been laid low ; and it is as a part of
such a range that we must regard both the highlands and
lowlands of Mount Desert.

The narrow limits of the Island suffice to give us an
understanding of its granitic belt ; but in the present sec-
tion the Island must be regarded merely as a part of New
England. It is only from a general survey of a consider-
able area that a just view of its parts can be gained. Let
the reader, therefore, now recollect what he has seen of
New England elsewhere, and follow a rapid sketch of its
history as a wasting land.

Although New England is a rugged country, an extended
view from its hill tops brings to sight a comparatively even
sky line, at whose elevation extensive uplands often stretch
many miles without great inequality of height. The moun-
tains that rise above this sky line and the valleys that sink
below it may be for the moment left out of consideration.
The upland is the most general feature of inner New Eng-
land, and must be distinctly recognized. This upland
surface, gradually descending towards the seacoast, merges
into the lowland that was mentioned in the first sentence
of this essay. The whole is manifestly a surface of denuda-
tion, for its stratified rocks are nearly always exposed on
edge, and their former extension has been greatly cur-
tailed ; while its crystalline rocks in almost every case pos-
sess a coarseness of texture and a structural relation to

60 AN OUTLINE OF THE

their surroundings that indicate intrusion at great depths
beneath the surface of their time. Now it is a law, well
demonstrated in the science of land sculpture, that an even
upland of large extent, like that of the New England pla-
teau, in which there is at present no sympathy between
rock structure and surface form, can be produced only in
the later stages of a long cycle of denudation, when the
region has wasted from whatever height it once possessed
nearly down to sea level, or base level as it is conveniently
called. The New England upland was therefore once, not
only at its margin as now, but across its whole extent, a
lowland of denudation standing near sea level ; and its
present elevation must have been given to it at some sub-
sequent time by an unequal tilting which depressed part
of its former extent beneath the sea, and which raised the
inner portion of its area one or two thousand feet.

The reader must guard against making too even a
picture of this ancient plain of denudation. It was by
no means a dead-level plain, but a rolling surface of mod-
erate relief, — an almost plain surface, for which I have
coined the term ijeneplain. During the long cycle of
denudation, the region was not entirely worn down to sea
level, but it was greatly reduced from the height that it
once possessed, and only low hills remained to represent
most of its ancient mountains. At certain points, not
even the peneplain stage was reached. The view across
the New England upland nearly always includes, in one
direction or another, an eminence rising above the general
sky line ; and of such, Monadnock in southwestern New
Hampshire is one of the most beautiful examples. These
eminences, once overlooking the lowland, but now overlook-
ing the plateau, are residual mountains, which by reason
of their excessive hardness escaped the nearly complete
denudation that the rest of the peneplain suffered. The
White Mountains seem to be simply a cluster of Monad-

GEOLOGY OF MOUNT DESEET. 61

nocks. The range of Mount Desert is a series of
Monadnocks, close to the line where the sea now lies
on the land.

It is only in a later cycle of denudation, since the low-
land peneplain was uplifted into a rolling plateau inclining
towards the sea, that the valleys of New England were
carved out. Where the plateau rose high, the valleys
have been cut deep ; where it rose but little, there are only
shallow trenches in the upland. Where the rocks of the
uplifted peneplain are relatively hard, the valleys are as
yet, in the present cycle of denudation, opened only to a
moderate width ; where the rocks are weak, the valleys
are opened so wide that new local lowlands, local pene-
plains of the second order, or of a second generation, have
been developed. Thus the rocky floor of New England
is diversified, and of this rocky floor Mount Desert is a
little part.

Just as we must avoid too artificial a conception of the
plain to which New England was reduced by the great
denudation, so we must guard against too rigid an assump-
tion of a perfect standstill of the land during either the
greater or the lesser cycle of its degradation, and too
violent an assumption of its immediate ascent from a
lower to a higher altitude. It is most probable that many
minor oscillations of level occurred during the cycle while
the peneplain was in development, and that the elevation
and tilting of the peneplain into the inclined upland was so
gently accomplished, that, had we then been here to watch
its rise, we might have watched in vain during our too brief
centuries. It is also probable that, since the uplift and
the beginning of the new cycle in which the valleys have
been etched out, minor oscillations have again upheaved
and depressed the land. It is only the greater changes
of level that can be detected in the more remote history
of the sculpture of the land ; it is only as we come close to

62 AN OUTLINE OF THE

the present time that the minute records of slight and
brief oscillations can be detected. The moderate depres-
sion by which our lower valleys have been, as we shall see,
drowned into bays, and the lesser elevation by which our
coastal slope has risen with a half-smooth sea cover on its
back are important to us, not by reason of their magnitude
or their duration, but simply by reason of their recency.
They must not be regarded as exceptional, but only as
giving indication of the uneasiness that most likely always
has and always will characterize the land.

There is nothing on Mount Desert, or on the coast of
Maine, that suffices to define the geological date of the
elevation by which the two cycles of denudation just
described were separated ; yet when the field of inquiry
is extended so as to include all parts of the uplifted
peneplain, which is found to spread far to the southwest,
even to Alabama, its denudation may be correlated with
the deposition of various fossiliferous sediments, and thus
the completion of the peneplain may be placed in its
proper position in geological chronology. Strata of late
Cretaceous age in New Jersey are found overlapping the
seaward margin of the peneplain ; hence it is believed to
have been fairly well completed in late Cretaceous time ;
and the period of its elevation and consequent etching is
regarded as post-Cretaceous, or somewhere in the Tertiary
period. This is manifestly rather indefinite ; future inves-
tigations will probably define it more sharply ; but it is a
significant step in the right direction. Before this small
step was made, the date of the denudation of New Eng-
land was entirely unfixed, and very diverse views were
held on this subject. The making of the peneplain was
by some thought to be as old as the red sandstones of the
Triassic formation in the Connecticut valley ; and the
valleys were considered by others to be as young as the
time of the ice invasion, to whose erosive powers they

GEOLOGY OF MOUNT DESERT. 63

were ascribed. The truth as it now appears lies between
these extremes.

The geological dates of the intrusions and deformations
that the Island has suffered are even more indefinite than
the times of its denudation. Accepting the provisional
date of Cambrian for the lower members of the bedded
series, and late Cretaceous for the end of the denudation
of the peneplain, the deformations and intrusions must be
placed somewhere within the long intermediate interval.
This is like saying that a certain battle occurred some-
where between the time of the founding of Rome and the
invention of printing; but if its date had been previously
still less determinate than this, we should be glad enough
to have even so wide a limitation of its occurrence. It
is probable that comparisons of the structure of Mount
Desert with similar structures in other parts of New Eng-
land will in future suffice to set narrower limits to the
dates of several of the events whose time of occurrence is
now so loosely circumscribed.

The Glacial Invasion.

It was over a country thus made and unmade, over an
uplifted peneplain surmounted by isolated and clustered
Monadnocks, and dissected by newly etched valleys and
valley lowlands, that the ice sheet crept down from the
north. I shall not enter on the cause of its coming, or
on its source ; suffice it to call attention to the manifest
marks of its presence. Wherever the rocky floor of the
Island, or of almost any part of New England, is freshly
uncovered, it is found to be more or less smoothed or
rounded and distinctly striated or grooved, as if it had
been severely rubbed down by some gritty burnisher. Such
surfaces may be seen at innumerable points along the rocky
shore, of Mount Desert, where the drift has lately been
stripped off and where the waves have not yet made

successful attack. On the mountain tops the striee are
weathered off, but the rounded form of many ledges is a
significant product of glacial action. The strife trend to
the east of south, sometimes deflected to one side or the
other by the uneven form of the hills and mountains,
but generally persisting rather regularly in their course.
These markings are so perfectly matched by those seen
on the rocks under the creeping ice streams of Switzer-
land, or alongside of the decaying ice sheet of Alaska,
that it is unreasonable to doubt that they were produced
in the same way. Mount Desert, Maine, New England, all
our northern States and Canada beyond them, are thus
engraved ; over all of them once lay an ice sheet at least
twice as large as that which now swathes Greenland ; and
this so little time ago that the ice scorings are still fresh,
where protected only by a thin layer of drift. The ice
moved outwards towards its margin; and in Maine this
was to the south-southeast. We must imagine it advan-
cing beyond the present coast line, and terminating in an
ice wall in the sea, yielding innumerable icebergs to float
for a time southward in the cold 'long-shore current.

There is a curious transportation of boulders that must
be associated with the glacial scoring of the rocks, for it
runs in the same direction, and it is of too great an amount
to be of postglacial date. It is true that on the young
sea cliffs, and at the foot of many of the steeper ledges
on the mountain sides, the wasting of the rock progresses
rapidly, and blocks have been loosened and moved over
short distances, or have fallen down the talus slopes, since
the ice sheet retreated ; but so local a distribution of rock
fragments will by no means account for the long carriage
of the innumerable boulders that are scattered far and
wide over the country. Boulders of the easily recognized
greenish schists of the western coast of the Island are
found removed southward from their parent ledges, in

GEOLOGY OF MOUNT DESERT. 65

areas underlain by rocks of other kinds. Boulders from
the granite of the central belt are moved southward in
plenty over the surface of the bedded and volcanic rocks.
Not only so ; blocks of a coarse gray granite, easily known
by its large crystals of whitish feldspar, but not occurring
in the rocky structure of the island, are found here and
there over its surface. They come .from the mainland,
where this kind of granite is well known. One of these
boulders was to be seen, some years ago, close to the
summit of Green Mountain. Further than this, there are
fragments, generally of less than a foot in diameter, of a
fossiliferous shaly flagstone, sparingly distributed over the
western half of the Island ; these are easily identified as
belonging to a belt of Devonian strata some miles north-
ward from the mainland coast. No such rocks occur in
place on the Island. All of this peculiar transportation of
erratic boulders is ascribed to the ice sheet, aided in some
cases by its subglacial streams. The boulders are simply
the larger fragments that the ice sheet dragged along
beneath it, or carried in its lower portion.

The unconsolidated drift by which the lower rocky floor
of the island is generally covered frequently possesses a
structure that gives still further indication of land-ice
action. Its lower part, lying close packed on the striated
bedrock, is a compact unstratified mass of stones, sand,
and clay ; the stones are of both local and distant origin,
being more worn and striated if from a distance, while
those that have been brought but a little way show fewer
signs of severe usage. Deposits of this kind are called by
the Scotch name, till. They are very generally spread over
the New England plateau, where they diminish the rugged-
ness of the rocky surface. Till also occurs in the valleys ;
but here it is often covered over by water-washed sands or
clays of somewhat later date. On the " Monadnocks," the
till is scanty : above five or six hundred feet, the Mount

66 AN OUTLINE OF THE

Desert range exposes a large surface of bare rock. In
many parts of New England, the till is accumulated in
large rounded hills, of oval outline and smoothly rounded
profile, called by the Irish name, drumlins. These are
common in the neighborhood of Boston, and further inland
about Brookfield and Pomfret; but with half an exception
they are absent on Mount Desert. This half exception is
the long smooth northern slope of Beech Hill, southwest
of Somesville; apparently a deposit of till simulating a
half-drumlin form, extending only northward from the
rocky knob of the hill summit ; while to the south, where
a completed drumlin would descend symmetrically, there
is a rocky slope.

Under the ice and in its lower part many blocks were
moved from their native ledges ; the preglacial soil was
scraped off, and the rock beneath was rubbed down. Val-
leys were deepened and hills were degraded ; but by com-
paring regions inside and outside of the glaciated area, it is
plain that as a rule no great erosion of hard rocks must be
attributed to glacial action. The excavation of our valleys
in the uplifted peneplain was a large piece of work com-
pared to the scraping of the surface by the ice sheet ; and
the time required for the valley making was much longer
than the duration of the ice invasion. Yet on Mount
Desert there are certain considerable topographic features
whose origin has no other explanation than excavation by
the rough-shod ice. These are the deep transverse valleys
by which the mountain range is so curiously divided. In
its moderate length of twelve miles, it is notched almost
down to or beneath sea level no less than nine times.
Instead of a mountain ridge as continuous as the granite
of the central belt, we have a beautifully diversified succes-
sion of rounded domes, separated by deep gorges ; and in
nearly every gorge there is a lake or an arm of the sea,
almost directly in the axis of the range. There is no

GEOLOGY OF MOUNT DESERT. 67

understanding of this exceptional form, unless it can be
explained as a glacial modification of a mountain range
previously serrated by transverse notches of moderate
depth, down from which lateral ravines descended to the
lowlands, north and south. It has therefore been sup-
posed that the more rapid flow of the ice through these
preglacial passes gouged them out as deep as the open
lowland on either side, or even deeper.

There are few well marked examples on Mount Desert
of the curious deposits of gravel and sand, elsewhere com-
mon enough in New England, that were formed during the
closing stages of the ice period. Many of the mainland
valleys are half clogged with heaps, ridges, or plains of
these loose materials, lying upon scored rock or upon a
varying sheet of till ; their origin being ascribed to streams
that ran from the waning ice sheet, discharging their load
of sand and gravel in the open spaces along the ice border.
The absence of such gravels on Mount Desert would imply
that during the disappearance of the ice sheet the streams
from the mainland avoided the island, and followed by
preference the lower districts east or west. The surface
deposits of drift are, however, frequently of a gravelly
nature, especially at altitudes above that of the clays later
described, and below elevations of four to six hundred feet ;
and these may be ascribed to the wash of streams and
currents as the ice melted away. Above the head of Bass
Harbor, they attain an uneven form, characteristic of the
gravel mounds or kames of the mainland ; but this is
exceptional on the Island.

Postglacial History.

What with the deepening of the transverse valleys and
the irregular deposition of the till over the rocky floor,
we find the drainage of the Island peculiarly embarrassed
since the disappearance of the ice. In preglacial time,

68 AN OUTLINE OF THE

when the drahiage lines had been for a long time under
control of sub-aerial streams, it is most probable that there
were no lakes on the Island in which the streams were
detained on their way to the sea ; now there are twelve
lakes, several of them of good size and most picturesquely
placed amid the mountains. If the land stood a little
higher, Somes Sound would be transformed into a lake,
for its waters are deeper in the line of the mountain range
than farther south at its Narrows. It is interesting to
notice that the streams which enter Denning Pond (Echo
Lake) and Great Pond come from the south, the head-
waters of the latter lying distinctly beyond the axis of the
range ; and that the northward outlets of these lakes lead
their waters into the head of Somes Sound, through which
they pass back again southward across the line of the
range to the sea. Such an arrangement of streams would
be unnatural or impossible in a region whose drainage
had been developed under the ordinary processes of at-
mospheric wasting ; and must be, with the occurrence of
the lakes deep in the mountain axis, referred to glacial
action. It is noteworthy, however, that while the rock
scorings, the transported boulders, and the till are all
taken as demonstrating the existence of an ice sheet in
the recent past, the occurrence of the lakes and of the
reversed or northward drainage is not generally regarded
as belonging in the same demonstrative category. The
latter facts may be plausibly explained by the action of
the ice, the existence of which is to be otherwise demon-
strated, rather than regarded as independent indications
of ice action, even in the absence of other evidence.

The altitude of the land at the time when the ice inva-
sion began is not known, except that for a considerable
preglacial time it must have been somewhat higher than
now, to allow the excavation as land valleys of the many
arms of the sea that now break up the coast line of Maine.

GEOLOGY OF MOUNT DESERT. 69

But at the closing stages of the ice invasion and for a time
afterwards, the land must have stood lower than now ; for
beds of stratified clay bearing marine fossils are found at
various points on the lowland of the Island and the main-
land, up to about two hundred feet above the present sea
level. Judging by the relation of these clays to the washed
gravels and sands on the higher slopes, it is probable that
the submergence about the close of glacial time amounted
here to at least three hundred feet. The clays are relatively
scanty on the southern side of the Island ; they are exposed
above the shores of Wasgatt Cove, near the Narrows of
Somes Sound, and in Seal Harbor. On the northern low-
land, they have a wide extension, and conceal the rocky
floor over much of the district. On the mainland, the
clays and sands are so plentiful over the coastal lowland
that they greatly diminish the ruggedness of the rolling
foundation on which they lie ; and they efficiently aid the
deposits of till in displacing the rivers from their preglacial
courses.

During the depression indicated by these stratified de-
posits, Mount Desert was not a single island, but a row of
imperfectly connected mountains. Somes Sound was then
a thoroughfare, and had several fellows on either side.
Nearly all the lower stretches of the Island were sub-
merged. Not only so ; at that time the scanty remnants
of rocks other than the granite, now visible in patches
along the shore, must have been entirely concealed beneath
the sea. The geological structure then visible would have
been extremely simple.

The depression of the land about the close of the glacial
period cannot have been maintained long at any one level,
for nowhere on the slopes of the island are there shore
lines of as great distinctness as those which mark the
present margin of the sea. A depression of much more
than three hundred feet has been inferred by Professor

70 AN OUTLINE OF THE

Shaler, but if it amounted to as great a measure as he
concludes it must have been of brief duration, as its
records are indistinct.

At the present time the land has but partially recovered
from the late glacial submergence. Many of the preglacial
valleys and valley lowlands are submerged as sounds and
bays, and the coast line is probably at least twenty or
thirty miles farther inland than it was in preglacial time.
It is for this reason that Mount Desert is isolated from
the mainland, and that the many other islands fringe the
coast. All of these were once hills on a coastal lowland,
and when thus exposed there would have been better
opportunity than now of discovering the true history of
the pre-granitic rocks.

While in its present attitude, the s'ea has begun to make
its mark along the shore. As is the habit on steep coasts
of hard rock, the waves excavate caves wherever the rate
of cutting on the water line at the base of the slope is
faster than the wasting of the slope above ; but it is
seldom that this relation is found unless aided by joints or
other lines of structural weakness in the rocks near sea
level. Generally the wasting of the face of tlie slope on
young shore lines about keeps pace with the undercutting
of the waves at the base ; and thus a rocky bench is
formed a little below water level, surmounted by such
vertical faces as Great Head and Otter Cliffs. A consid-
erable part of our rocky shore is benched in this manner,
but less emphatically. At other parts of the shore, where
the land slope is more gentle, yet well exposed to inrolling
surf, the loose rocks gathered from the adjacent headlands,
and carried in by storm waves from the shelving bottom,
are thrown along the water's edge a little beyond high-
water mark, making a sea wall, such as occurs in a
re-entrant on the shore south of Southwest Harbor. In
more protected situations, the embankment formed by the

GEOLOGY OF MOUNT DESERT. 71

waves consists only of cobble stones, or of gravel and
sand, as at various points along the western coast. The
embankment may be built across the mouth of a bay, thus
enclosing Long Pond from Bracy Cove, east of Northeast
Harbor ; or it may stretch out and tie an island to the
shore, as at Bar Harbor. Bars of this kind are better
developed on sandier and shallower shores than on the
steep and broken coast of Mount Desert.

As the waves rise and fall in broken rhythm on the
shore, as the tide flows and ebbs across the littoral belt,
so the seas of former times have risen and fallen in
uneven measure on the uneasy land ; the rocks have
grown and wasted ; the ice of the North has crept down
and melted away ; — all shifting back and forth in their
cycles of change. Only one scene lies before us of the
many that have floated through the past.

If introduced, of very early introduction, but probably indige-
nous. Very variable. A form from Sea Wall (Rand), having
extremely small flowers with corolla scarcely spreading, and

well to the description of var. Tatarica, Benth., but does not
agree with herbarium specimens. It appears to be intermediate

Pond shores ; rare. Breakneck Ponds (F. M. Day) ; — Somes

closely approaches U. bifiora, Lam., and may perhaps prove to
be that species. "The flower has the spurs of U. biflora very
decidedly, but the foliage and the bladders are those of U. gibba.
The spur here is oblong, narrow, not curved but projecting
straightwise, and the perianth is somewhat larger than is gen-
erally the case in U. gibba. Other specimens with foliage and
bladders better represented might show this to be U. biflora,
but at present it is safer to call it ' U. gibba verging towards
U. biflora in flowers.' " Dr. Thomas Morong in litt.

timber. At Somesville, it is said, there was an oak wood on
the shores of Somes Harbor, which attracted the attention of

Abraham Somes, of Gloucester, Mass., when he chanced to sail
up the Sound about 1760. He spent the summer in that vicinity
making barrel staves, and then returned home with his cargo.
The following year he returned to Somes Harbor for the same
purpose, and finally, in 1762, built a house on the shore of the
harbor near the present steamboat wharf, and began the per-
manent settlement of Mt. Desert Island.

S. angustifolium, Mill. S. Bermudiana, L.*

Common in grassy places. Whatever may he the fact in re-
gard to the specific rank of S. anceps and S. vmcronatum, all the
Island forms must be referred to S. angustifolium. A specimen
with a single spathe, collected by F. M. Day, in 1882, probably
in the vicinity of Bar Harbor, has been somewhat doubtfully
marked S. anceps in the herbarium. A recent and more careful
examination, however, seems to show that it is nothing more than
S. an giisti folium with smaller, probably immature seeds. It is
worthy of remark that not a specimen of the true *S^. anceps form
has yet been found on the Island, although S. angustifolium is
so very abundant. This fact is evidence that these forms of the
plant merit at least varietal distinction.

G. laxa, Scribner.

A coarse leafy grass, 2°-4° high, with a diffuse ample panicle
and oblong, somewhat turgid spikelets. Sheaths scabrous, the
lower exceeding the internodes. Ligule about 1" long, thin,
lacerate. Leaves 8'-15' long, 3"-4" wide, very rough-scabrous,
both sides tapering to a sharp point or the lower ones abruptly
sharp-pointed. Panicle 7'-9' long, the main axis and branches
strongly scabrous, lower branches in twos or threes, the upper
solitary, the longer and usually widely spreading lower ones
3'-5' long. Spikelets oblong or broadly ovate, 3-5-flowered,
about 2" long, much exceeding the pedicels, and from V'-l\"
wide. Empty glumes unequal, scarious-margined, the larger
second glume about one half the length of the first floret.
Flowering glumes rounded on the back, \"-l\" long, broadly
obovate, obtuse, with a narrow scarious margin above, 7-nerved,
nerves not prominent. Palea nearly equalling the glume, the
keels smooth, strongly curved above. Closely allied to G. Cana-
densis, but the smaller spikelets are green or purple tinged, and
the more obtuse floral glume scarcely exceeds the narrower palea.

perhaps a hybrid between this species and P. distans, Norwood
Cove (M. L. Fernald).

Sea beaches. Somesville; Ovens; Thomas Bay; Southwest
Harbor; Mt. Desert Narrows, and elsewhere. "This form is
distinguished from P. marttimahy its smaller and weaker habit,
and by having the keels of the palea smooth below and only very
minutely scabrous above. In P. maritima the keels of the palea
are strongly fringed nearly or quite to the base." F. Lamson-
Scribner. More recent examination shows this form to be spe-
cifically distinct, and should bear the name in the Manual of
P. angustata (R. Br.).

FESTUCA, L. Fescue Grass.
F. ovina, L. Sheep's Fescue.

Common especially on or near the shore. Also on Cranberry
Isles. All specimens from Mt. Desert and vicinity are referred,
however, to F. rubra, L., by Prof. F. Lamson-Scribner, which

he considers without doubt a distinct species from F. ovina.
Specimens from High Head, Great Cranberry Isle, Little
Cranberry Isle, and Thompson Island, may be referred to var.
genuina, Hack. A specimen from Indian Point road, Somes-
ville, appears to be var. fallax, Hack.

''In F. rubra the leaves of the culm and sterile shoots are
similar, the ligules in the latter are not auriculate, and the
shoots themselves are extra-vaginal; i. e. the buds of the
branches at the base of the culm burst through the base of
the leaf sheath in the axil of which they are formed. In
F. ovina the leaves of the flowering culms and sterile shoots
are unlike, the ligules on the latter are auriculate and the
shoots themselves are intra-vaginal; i. e. the buds in the lower
leaf axils grow up out of the sheaths and do not break through
them below. F. ovina is strictly tufted, while F. rubra extends
more or less by rootstocks." F. Lamson-Scribner.

Order I. SPHAGNACE.E. Peat Mosses.

List prepared by Edward L. Rand, assisted greatly by Edwin
Faxon and Prof. Daniel C. Eaton, and arranged mainly in ac-
cordance with the writings of Dr. Carl Warnstorf, of Neuruppin,
Germany.

The plants catalogued in the following list have been col-
lected mostly by Edwin Faxon and Edward L. Rand ; the
determinations are by Dr. Carl Warnstorf. In view of the
great difficulty of finding descriptions of the various species
and varieties, it has been thought wise to give freely refer-
ences to Lesquereux and James's "Mosses of North America,"
and to Dr. Warnstorf's articles on North American Sphagna,
to be found in Coulter's Botanical Gazette, Vol. XV., in the
numbers for the months of June, August, September, and Oc-
tober, 1890, — both of which works can be consulted with little
trouble. In cases, furthermore, where descriptions are not
there given, they have been either translated or specially pre-
pared for this list by Prof. Eaton and Mr. Faxon. It has
not seemed best to include forms and sub-forms herein, since
most of them have little value except for the critical stu-
dent. Very many of them are, however, represented in the
Mt. Desert Herbarium. On the other hand, all varieties are
given, without regard to the distinctions on which they are
founded. The value, however, of most of the so-called color
varieties is very doubtful, since careful observations seem to
prove beyond question that the color of Sphagnum varies greatly
with the season. It is even a matter of doubt whether a given
plant of any species may not quickly vary through the influence
of temporary external conditions, assuming at one time the form
of one variety, at another time the form of another. This doubt-
ful value of varieties of Sphagnum furnishes an additional reason
for the exclusion of mere forms and sub forms from a local cata-
logue of plants.

Order III. BRYACEiE. True Mosses.

List prepared by Edward L. Rand, under the supervision of
Elizabeth G. Britton. Plants collected mainly by Walter L.
Burrage, John H. Redfield, Edward L. Rand, Edwin Faxon,
and Theodore G. White, determinations by Elizabeth G. Brit-
ton and Dr. Charles R. Barnes.

In view of the great importance of following the arrangement
and nomenclature adopted in some standard work of ready ref-
erence, and in view also of the great disagreement on these very
matters of arrangement and nomenclature among the authorities,
it has seemed wise to follow Lesquereux and James's ** Mosses
of North America" in the preparation of this list. Synonyms,
however, have been given where they seemed of real value;
some necessary descriptions have been added; and a few cor-
rections made where they were of real, not merely of verbal
importance.

DICRANELLA, Schimp.

D. squarrosa (Starke), Schimp.

In dense mats on sandy shore, Jordan Pond ; submersed (Rand).
As the specimens found are all sterile, some doubt has arisen
as to their identity. They are almost identical with specimens
collected by E. Eaxon at Ammonoosuc Lake, Crawfords, K. H.,
June 14, 1883, and very similar to specimens collected by Oakes
at the White Mts., N. H. (Sulliv. & Lesq., Musci Bor. Am.,
No. 245). The latter specimens were distributed as ^^ Meesia
longiseta, Hedw. var.?" Faxon's specimens, however, are
Dicranella squarrosa, and so with very little doubt are the
Mt. Desert specimens. The true identity of Oakes's specimens
is still in doubt. Especial thanks are due Dr. C. R. Barnes
and Mi's. E. G. Britton for the solution of these puzzling ques-
tions of identification.

dry, from a sheathing base, linear-acuminate, cuspidate, serrate;
lamellae about 50, each in section of a row of 5-7 cells, the mar-
ginal one much larger, transversely dilated, about twice broader
than high, very slightly convex, often almost plane; perichaetial
leaves longer, with a longer hyaline base. Pedicel 4-8 cm. long,
reddish below, pale above ; capsule erect, finally horizontal,

Division II. ALGM.

List prepared by Frank S. Collins. Plants collected by
Frank S. Collins and Isaac Holden.

So far as fresh water algae are concerned, the following list
contains only a few species which have come under the notice of
the collectors ; to make even an approximately representative
list would take careful collecting and study for years; this must
be left for future students. In the representation of marine
alga?, the list is more satisfactory, but here also it is undoubt-
edly far from perfect. For instance, there will be noticed three
species which find a place here only on authoritj"^ of minute
fronds observed on other specimens; it is more than likely that
there are other species equally deserving of a place, but not
equally fortunate in securing it.

The fact that thus far collecting has been done almost entirely
in the summer months accounts for the absence of some species,
which there is every reason to expect in this locality. Still,
allowing for these deficiencies, the list gives a fairly good idea
of the marine flora of the Island, — that sub-arctic flora charac-
teristic of the northern New England coast.

The arrangement of species, genera, etc., is based chiefly on
Engler and Prantl's "Natiirlichen Pflanzenfamilien, " which

228 FLORA OF MOUNT DESERT.

differs somewhat from the standard work of reference for this
region, Farlow's "Manual of the Marine Algae of Kew Eng-
land." Where the name here used differs from that emploj^ed
by Farlow, the latter is given as a synonym; in the case of si:)ecies
and genera not to be found in Farlow, short descriptions have
been given, which it is hojjed will enable the collector to recognize
the plants. Descriptions of the few fresh \vater algse will be
found in Wolle's "Fresh Water Algte of the United States."

This is the L. fasciculatum of Farlow's Manual, p. 182, but it
is doubtful if it is the European species of that name. The
Lithothamnia of northern Europe have been much studied during
the past few years, and it is quite likely that our plant belongs
to one of the new species formerly included under L. fascicula-
tum ; but it is impossible to decide without comparison of au-
thentic specimens.

T. percursum (Ag.), Aresch.

Forming light green or yellowish masses in warm upper
pools, usually mixed with various species of Enteromorpha,
Cladophora, etc. The frond consists at first of a single con-
ferva-like filament, which soon divides into two series of cells,
set side by side, the cells, usually a little longer than broad,
being set symmetrically, the cross walls exactly opposite. The
filaments are unbranched, usuall}"- .01 to .016 mm. diam. In
upper tide pools. Near Seal Harbor (Collins).

CATALOGUE OF PLANTS. 245

CAPSOSIPHON, Gobi.

Frond tubular, formed of longitudinally arranged gelatinous
cells, wbicli divide in two directions, the walls of the mother
cells persistent for a time, as in Glffiocapsa.

C. aureolus (Ag.), Gobi.

Resembles a slender unbranched Enteromorpha, but the cells
look like Gloeocapsa, being rounded, dividing by twos or fours,
the mother cell-wall showing somewhat after the division.
The longitudinal arrangement of cells is very distinct in the
filament, a little pressure on the cover glass under the micro-
scope often dividing the frond for quite a distance up and
down. This species seems to prefer localities where it is
exposed alternately to fresh and to salt water. Common on
stones in brook flowing from Long Fond through the beach
(Collins).

Division III. LICHENES.

List contributed by Dr. John W. Eckfeldt, and based on col-
lections made by him, by Miss Mary L. Wilson, and by others.
Plants determined by Dr. Eckfeldt, Miss Wilson, and Miss Clara
E. Cummings. As all collections have hitherto been made either
within a short period of time, or under adverse circumstances,
doubtless a more thorough examination of the Island would
extend the list very greatly. In the case of Dr. Eckfeldt's
collections the names of the special stations have in most cases
unfortunately been lost.
