PREFACE.

THE main object of the excursion, the results of which
are given in the following pages, was a purely scientific
one, viz. : the study of the Natural History of the north-
ern shore of Lake Superior. Another end proposed by
Professor Agassiz, was, to afford to those of the party
who were unaccustomed to the practical investigation of
natural phenomena, an opportunity of exercising them-
selves under his direction.

The party was composed of the following gentlemen :
Prof. Agassiz and Dr. William Keller, instructors, and
Messrs. George Belknap and Charles G. Kendall, stu-
dents, of the Lawrence Scientific School ; Messrs. James
McC. Lea, GeorgeH. Timmins, and Freeman Tompkins,
of the Dane Law School ; Messrs. Eugene A. Hoffman,
Charles G. Loring, Jonathan C. Stone, and Jefferson
Wiley, of the senior class of Harvard College ; Messrs.
Joseph P. Gardner and J. Elliot Cabot, of Boston ; Drs.
John L. Le Conte and Arthur Stout, of New York ; and
M. Jules Marcou, of Paris.

Interspersed throughout the Narrative are reports, care-
fully made at the time, of the Professor's remarks on
various points of Natural History, that seemed to him

likely to interest a wider circle than those more particu-
larly addressed in the second part of the book, which
consists of papers on various points connected with the
Natural History of the region, written, where not other-
wise specified, by Prof. Agassiz. This portion of the
work, however, does not aim at a mere detail of facts,
but is intended to show the bearing of these facts upon
general questions.

The Landscape Illustrations are taken from sketches
made on the spot, by Mr. Cabot. Those of the Second
Part were drawn and lithographed by Mr. Sonrel, a Swiss
artist of much distinction in this branch, and formerly
employed by Prof. Agassiz at Neuchatel, but now resident
in this country.

CHAPTER I.

BOSTON TO THE SAULT DE ST. MARIE.

WE left Boston on the 15th of June, 1848, at 8 A.M., in the cars
for Albany. The weather was warm, and we were well powdered
with dust, when, at about 6 P.M., we arrived at the ferry on
the Hudson. The Western appears to be more exposed to this
nuisance of dust than the other railroads, probably from the many
cuts through banks of crumbling clay and gravel. We were inter-
ested to hear that a contrivance for watering the track had been
proposed and successfully experimented on.

At the hotel we found the New York members of our party, which
now numbered eighteen. After tea we assembled in a large room up
stairs, where Prof. Agassiz made the following remarks on the region
over which we had passed : —

" The soil of this tract is of great variety, but everywhere presents this
feature : that its surface is covered with loose materials, all erratic, (or be-
longing to rocks whose natural position is distant from the points where
these fragments are found,) and all evidently transported at a very remote
epoch. These erratics are of all sizes, from sand to large rocks ; the larger
ones angular ; the smaller ones more or less rounded, scratched and polished,
as are also the surfaces of the rocks on which they rest. These polished
rocks have been noticeable to-day, especially to the westward of Worcester.
These marks we shall find still more strongly shown as we proceed north-
ward.

" We have nowhere seen unaltered rocks, but exclusively those of a
granitic character, metamorphosed from originally stratified formations by the

10 LAKE SUPERIOR.

action of heat. Thus, for instance, the blackish mica slate, with veins of
quartz, — which so frequently occurs on our route of to-day — is probably
clay slate, altered by intense heat, which has produced several varieties
of silicate of alumina. There is no clearly defined division between
these slates ; they pass without interruption from baked clay into
chloritic slates. In one place in the Connecticut valley we saw red sand-
stone, generally in a horizontal position, except where disturbed by trap.
Nearer Albany we passed through a region of highly metamorphic lime-
stone, belonging to the oldest geological deposits. We have also seen indi-,
cations of the Potsdam sandstone, one of the most ancient fossiliferous
rocks.

" As to the vegetation, it is to be remarked in general, that the features
of a country are given principally by its plants. These mark the variety of
the soil, and its formation. The forests which we have seen to-day consist of
a great variety of plants, mingled together. We have seen no forests com-
posed of one species of tree. In the mountainous parts, indeed, certain
species predominate, but elsewhere several are found in almost equal pro-
portions. Among these are various pines ; the white and pitch pines, the
spruce, hemlock, red cedar, and a few larches. Then the Arnentacene,
viz., oaks, birches, chestnut, beech, poplar, and the platanus or button wood,
(which is in a sickly condition, probably from injury done to the young
wood by frosts,) hickories, elms, locust, ash, and maples, but the latter fewer
in number. The hickories never form forests. About Niagara we shall
find the beech abundant. Of shrubs, we have seen a great variety : e. g.,
sumachs of several species, (whereas in Europe there is but one,) elder,
alder, cornus, viburnum, witch-hazel, willows, wild roses, and grapes. A
remarkable feature of the vegetation of this country is, the number of species
of grape, mostly useless for the manufacture of wine. Shrubs peculiar to
America, are the Kalmias ; viz., mountain-laurel and sheepsbane. In the
meadows are various grassy plants, carices, and ferns ; the latter in great
variety. These spots exhibit probably a condition analogous to that of the
Coal Period, in which the ferns, &c., prevailed. All the plants growing on
the roadsides are exotics, as are also all the cultivated plants and grasses.
Everywhere in the track of the white man we find European plants ; the
native weeds have disappeared before him like the Indian.* Even along the
railroads we find few indigenous species. For example, on the railroad
between Boston and Salem, although the ground is uncultivated, all the
plants along the track and in the ditches are foreign. From this circum-

* Old Tocelyn says the Indians call the common plantain (Plantayo major,') " the
•white man's foot."

NARRATIVE. 11

stance, erroneous conclusions have been drawn as to the identity of species
on the European and American continents.

" The combination of trees in forests is an important point in the physiog-
nomy of a country. The forests of Europe are much more uniform in this
respect than those of this country, from the greater variety of allied species
here. Tims, in Central Europe, there are but two species of oak, and no
•walnut whatever ; the so-called English walnut being a Persian tree. In
the United States there are over forty species of oak ; in Massachusetts
there are eleven kinds of oak, and six of walnuts and hickories.

"Another important point is the distribution of water. We have crossed
to-day three distinct basins, having no connection with each other, viz. , that
of the Atlantic coast, the Connecticut valley, and the valley of the Hudson.
It would be interesting to examine how far each of these basins has a pecu-
liar fauna."

June ~L6th. — At half-past seven this morning, after not a little wor-
ry, owing to the very defective arrangements at the railroad station,
we set off in the cars for Buffalo. Weather hot, but as our course lay
up the flat valley of the Mohawk, there were no more cuts, and the
dust was not so troublesome as yesterday. We passed through level,
well-cultivated fields, spotted in many places with the bright yellow
flower of the mustard, just in blossom.

This rich alluvial plain very early attracted settlers. Part of
it bears the name of the German Flats, from its first inhabitants,
and the names of the towns along the route, such as Manheim,
Palatine Bridge, &c., indicate an immigration from the Palatinate.
The Dutch and German blood is still predominant here, as is shown
by the names on the signs, the neat little red-painted houses, with
open loggias and drive-ways, and the huge barns of this race of
thrifty cultivators.

After an uncomfortable night in the cars, we found ourselves at
daylight surrounded by the forest. Huge unbranching trunks, clear
of undergrowth ; occasional clearings, with log houses, and the corn
or potatoes scattered among charred stumps. From Utica, west-
ward, along this road, one is constantly reminded of the West. The
land here, too, is much of it uncleared, cheap, and fertile ; on the
other hand, aguish. In short, the advantages and disadvantages
are those of the West. From the abundance of pigs and children,

12 LAKE SUPERIOR.

and the untidy look of the cabins, one conjectures the settlers are
mostly the former laborers on the railroad, or at least countrymen
of theirs.

June VI tli. — At 8 A. M. we arrived in Buffalo, after about thirty-
six hours' actual travelling from Boston, a distance of 527 miles.
We had previously ascertained that it would be advisable to wait
until the 19th before embarking for Mackinaw, in order to give time
for procuring stores, tents, &c., and had determined to spend the
intervening time at Niagara. On our arrival we found that the
morning train for Niagara was to start at 9 ; so leaving some
of the party to make arrangements, the rest of us took the cars and
arrived at the Falls about 11 o'clock.

The road thither presents a continuation of the same noble forest
of " first growth," but often broken by clearings. Our European
friends were much struck by the contrast with the region we had
left only yesterday. A large proportion of the trees were elms, not
the plume-like spreading elms of our avenues, but a straight, un-
broken, scarcely tapering trunk of sixty feet height, then abruptly
expanding with sturdy limbs at right angles into a round head.

In the afternoon we crossed to the Canada side. The museum
here contains an interesting collection of the birds and fishes of
the neighborhood. A camera-obscura, the field of which is some
twenty feet in diameter, placed on the edge of the cliff, gives exten-
sive views of the Falls. I was struck with the disproportionally
high tone of the sky in the landscapes it presented. The effect was
something like the glow that comes on after sunset.

In the evening we assembled in a hall leading to our lodgings at
the Cataract Hotel, (in that part of the building which overlooks the
Rapids,) and Prof. Agassiz, having displayed his portable black-
board, (consisting of a piece of painted linen on a roller,) gave
us the following sketch of the region passed over since his last lec-
ture : —

" East of Lake Ontario we have granitic formations, which were doubtless
islands in the ancient time, on whose shoves the later formations accumulated,
by deposition from the water, in successive beds, the later covering the more
ancient, except where these had in the meanwhile been elevated from the
primeval ocean along the shores of the high land already dry. Thus the

NARRATIVE. 13

older deposits form strips around the granitic regions ; the beds of sedimen-
tary rock becoming continually narrower with the rise of the continent and
the consequent contraction of the ocean. From this time there were three
basins, viz., the coal basin of Pennsylvania, that of the West, and that of
Michigan. It is evident that the north-east region was the earliest dry ; to
the westward all the formations are more recent.

" Wherever the water escaped towards the north-east, we have waterfalls
over precipices ; for instance, here at Niagara. Where depi'essions have
been formed in soft rocks between harder ones, we have valleys, as that of
the Mohawk.

"It is a remarkable fact, that the leading changes in the geological
features of North America take place in a north and south direction. Thus
the fissures forming the beds of the rivers, as those of the Connecticut, the
Hudson, the Mississippi, and the rivers of Maine. In the Old World, on
the contrary, most formations are parallel to the Equator, as the Alps, the
Atlas, and the Himalayas. Only two mountain chains run north and south,
the Ural, and the Scandinavian mountains, which are northern in their char-
acter. The longitudinal direction of fissures in this country is well shown
by the New York State Survey. The lakes of Western New York lie north
and south. So also Lake Huron and Lake Michigan. These longitudinal
fissures are sometimes traversed by others at right angles, as in the instances
of Lake Superior and Lake Erie. These fissures must have been formed
by the upheaval of the continent, the layers of already solidified rock being
lifted up or depressed. Rivers must have existed already in those early
ages, as is shown for instance in the ancient channel of the Niagara, (above
the Whirlpool,) which is filled with drift not found in the present channel.

" All the formations before spoken of are more ancient than the coal, vet
many of them consist of soft clay. The hardness of rock is thus no proof or
criterion of its age. These soft slates are nowhere more developed than in
New York, and nowhere have they been more carefully examined and des-
cribed. These details of facts are to be looked upon in the same light as
a mere list of dates or occurrences in history. But geology aims at a full
illustration of all these details.

" Passing to the vegetable kingdom : — As soon as we left the metamor-
phic rocks of Massachusetts, vegetation became much richer, because of the
limestone and marl deposits. It is remarkable how limestone favors not
only vegetable, but also animal life. In Switzerland, where the country is
divided between the limestone and marl region of the Jura, the sandstone of
the plain, and the granitic formations of the Alps, the cattle of the latter
region are not more than one-third of the size of those of the former.

14 LAKE SUPEKIOR.

'Among the plants peculiar to this country, are many in whose ana-
logues in Europe many interesting chemical products have been traced.
Very little has been done here in organic chemistry, and it is a matter which
might well occupy one's lifetime, to ascertain the chemical relations of
analogous plants of the two countries, (for instance, Angelica, wal-
nut, &c.) Tracing the forest vegetation, we have seen lately very few
pines, but principally maples, elms, and ashes ; and here at Niagara, almost
exclusively elm, beech, hickory, ash, and arbor-vitas, which is very rare in
Massachusetts."

Jane 18£/i. — We met again this morning in the hall, where Prof.
Agassiz had prepared diagrams illustrating the geology of Niagara,
which he explained as follows : —

" The surface of the soil, both on the Canadian and on the American side, is
covered with gravel, containing fossils in great numbers, and stones of all sizes,
from that of a hen's egg to large bowlders. This stratum is now disunited by
the action of the river, but was originally continuous, as is shown by the
fossils, and by the fact that on the intermediate islands, where it has escaped
the action of the water, it is still present. The fossils form a bed extending
horizontally to the river bluffs, but not beyond ; they occur in great num-
bers, covering the surface of the soil everywhere, and contributing to the
great luxuriance of the vegetation. These fossil shells, doubtless, inhabited
the river in former times, when its bed was the mass of gravel, &c., on which
they now rest, the bluffs being at that time its banks. They are of species
now living in the river, of the genera Unio, Cyclas, Melania, Paludina, and
Planorbis. Hence we conclude that this bed was formed when the river
filled the whole valley, at which time it had a breadth varying from one to
seven miles, and averaging three or four. Probably at that time it resem-
bled the present Rapids above Goat Island. Afterwards, from the accelera-
tion of the current, owing probably to the opening of fissures which lowered
the level of Lake Erie, the two present channels were cut down to the rock,
and the river reduced to its present level."

Afterwards we went over to Goat Island, and blessed once more
the good sense that has kept this place undisturbed. The decaying *
wood and fungi of the damp woods here afforded an abundance of
specimens to our entomologists. The variety of trees and shrubs on
these islands is remarkable. On the little islet (only a few feet
in extent,) connected by a foot-bridge with the toll-house, Prof.

NARRATIVE. 15

Agassiz pointed out seven different kinds of trees, viz., arbor
vitoe, red cedar, hemlock, bass-wood, chestnut-oak, white pine, and
maple. The Professor also pointed out the shell-bed of which he had
spoken. The shells are very numerous, as may be readily seen in
the crumbling bank on the outer side of the island. At the upper
end of the island, vast numbers of delicate ephemera-like insects,
with long filaments, were fluttering about, particularly under the
trees.

Some of us had never seen the Falls, and none of us at this season
of the year, when the mass of water is greatest. Coming at length
in sight of them, we were struck with the thickness of the sheet at
the pitch of the English Fall, particularly in that part of it between
the apex of the Horseshoe and the middle of the cataract on the
Canadian side.* It bends over in a polished, unbroken mass, as of
green glass over white. Some one said the average depth of water
at that point was about fourteen feet. Other remarkable features are,
the distance to which the water is projected, the rocket-like bursts of
spray from the falling sheet, and the sudden spouting up of the mist
at intervals from below, as if shot from a cannon. These sheets of
mist rise high above the Fall, and move slowly down the river in
perpendicular columns, like a procession of ghosts. On the whole,
the difference of season is in favor of that when the river is lowest,
the features of the scene, particularly the Rapids outside of Goat
Island, being rather obscured than improved by a greater depth of
water.

After tea, the following remarks on what we had seen were made
by Prof. Agassiz : —

" If we follow the chasm cut by the Niagara River, down to Lake Ontario,
we have a succession of strata coming to the surface, of various character
and formation. These strata clip S.W. or towards the Falls, so that in their
progress to their present position, the Falls have had a bed of very
various consistency. Some of these strata, as the shales and the Med-
ina sandstone, are very soft, and when they formed the edge of the Fall, it
probably had the character of rapids. But wherever it comes to an edge of
hard rock, with softer beds below, the softer beds, crumbling away, leave a

circle within the recollection of persons now living.

shelf projecting above, and then the fall is perpendicular. Such is the case
at present ; the hard Niagara limestone overhangs in tables the soft shales
underneath, which at last are "worn away to such an extent as to undermine
the superincumbent rocks. Such was also the case at Queenston, where the
Clinton group formed the edge, with the Medina sandstone below. This
process has continued from the time when the Niagara fell directly into Lake
Ontario, to the present time, and will continue so long as there are soft beds
underneath hard ones. But from the inclination of the strata, this will not
always be the case. A time will come when the rock below will also be
hard. Then, probably, the Falls will be nearly stationary, and may lose
much of their beauty, from the wearing away of the edge, rendering it an
inclined plane. I do not think the waters of Lake Erie will ever fall into
Lake Ontario without any intermediate cascade. The Niagara shales are so
extensive that possibly at some future time the river below the cascade may
be enlarged into a lake, and thus the force of the falling water diminished.
But the whole process is so slow, that no accurate calculations can be made.
The Falls were probably larger and stationary for a longer time, at the
" Whirlpool " than anywhere else. At that point there was no division of
the cataract, but at the " Devil's Hole " there are indications of a lateral
fall, probably similar to what is now called the American Fall. At the
Whirlpool, the rocks are still united beneath the water, showing that they
were once continuous above its surface also."*

Afterwards, some of us went to bathe by moonlight in the
" Hermit's Fall," a little cascade eight or ten feet in height,
between Goat Island and the islet at its upper end. It is so
called from a crazy Englishman who lived for some time in a hut on
the other side of the island, and was finally drowned in bathing at
this place. There is, however, little danger, as the water is shallow,
and just below the pool a large log extends across the stream, which is
only some twenty feet wide. The " Hermit " was probably tired
of his own society at last, as he had been already of other people's,
and took this method of getting rid of it. The place, indeed, one
could conceive might be dangerously attractive to one tired of life.
It is so shaded and shut off by the overhanging trees of the island,
that one might fancy it a mountain stream a hundred miles from any

founded, are derived from Prof. James Hall's investigations in the New York State
Survey. A.

human habitation. The little . cascade, near at hand, drowns the
roar of the great one, and though by day it cannot boast of any
great privacy, yet at night very few even of the most romantic
moonlight strollers get so far as this.

The power of the water was greater than I expected, and difficult
to bear up against, even in a sitting posture. It was not a simple
pressure, but a muscular force, like a kneading or shampooing by
huge hands. We crawled in at the side of the Fall, and found a
hollow underneath the shelving edge, large enough for several to sit
at once, quite free from the water, which shoots over like a miniature
of the great cascade below. With some difficulty, from the pounding
of the falling water, we penetrated through the sheet in front, and
came out into the pool, the bottom of which is smooth rock. Close to
the surface there was a strong current of air clown the stream, not
perceptible at the height of two feet.

Afterwards, in walking round the island, we saw on the cloud of
mist over the English Fall, a lunar rainbow, glimmering with a
pale, phosphorescent, unearthly light, and showing prismatic colors,
but not quite joined at the top. Some of the party afterwards saw
it complete.

June ~LQth. — Took an accommodation car on the Lockport Railroad
as far as the Suspension Bridge, (about a mile below the Falls,) of
which the piers were finished and a rope stretched across, bearing
suspended a basket, in which some adventure-loving person was being
hauled across. From the bridge we walked along the bank through
the woods to the Whirlpool. The river, when thus seen from above,
is of such a dark and solid green, that it is difficult to persuade one's
self that it is not occasioned by some colored matter suspended in
the water. At intervals we got glimpses of the Fall, between the
high perpendicular banks enclosing it as in a frame. The slow,
heavy plunge of the water was distinguishable to the eye even at
this distance, but the roar was hardly audible.

Rattlesnakes are found among the rocks about these cliffs, and one
had been taken alive the day before, in the path leading down to the
Whirlpool. There is said to be a mound of their bones in the neigh-
borhood, erected in token of full revenge by some Indians whose
chief had been killed by a rattlesnake's bite.

18 LAKE SUPERIOR.

Returning to the Suspension Bridge, we went on board the little
steamer, " Maid of the Mist," which runs up to the foot of the
Falls. I confess I was doubtful as to the advantages to be gained
bj any one who had crossed the ferry so often as I had, but I was
old traveller enough to know that one oftener repents of not going
than of going, and went accordingly, instead of returning by the
cars with the more skeptical of the party. The result showed the
soundness of the principle. Many things are to be learned by such
close proximity, (for the boat, true to her name, runs actually into
the mist at the foot of the Fall,) and may be studied more conveni-
ently in the steamer, with a chance to dodge any extraordinary
shower of spray, than in an open skiff. I saw plainly here, what I
had not been able to satisfy myself of before, that the catenary curves
in high waterfalls, insisted upon by the " Oxford Graduate,'"' are
fully exemplified in the greatest cascade of the world.

At half-past two P. M. we took the cars for Buffalo, and as the
steamer was not to start until seven, we had some time on our
hands after our arrival there, which we spent in making some last
purchases, and in seeing the place.

The number of Germans here is a prominent feature. At the
Post-office there is a separate delivery for " Deutsche Briefe."
Another feature, striking to a New Englander, though common to
all the towns in New York, (which justify themselves probably by
the example of their great city,) is the number of pigs running at
large in the streets. When at length we went on board the
" Globe," we found everything in confusion. Bye and bye, how-
ever, the confusion subsided ; even the escape-pipe abated its
vehemence by degrees, and at last became silent, and still there
seemed to be no movement towards starting. But in proportion as
the boat became quiet, the passengers became noisy for departure,
and at last, after much expostulation, and finally the threat of leaving
altogether, at half past ten we got under weigh.

June 20$, — Weather pleasant, wind S.S.W., strong. The water
green, but less so than at Niagara. This forenoon we took possess-
ion of a little cabin in the after part of the vessel, to listen to the

following account from the Professor, of the forest trees about
Niagara, illustrated by specimens gathered the day before on the
spot :—

"1. Coniferce, (pine family,) remarkable for the apparently whorled
arrangement of their branches, and for their evergreen leaves ; in most cases
they form hard cones, but one has soft, berry-like fruit. The seeds are
naked, winged, resting on the scales. The leaves are peculiar, the nerves
not being spread, but often gathered into compact bundles. The Coniferce
existed at a very early geological epoch. This was the first family that
became numerous after the ferns. Their remains are easily recognized
under the microscope by the circular disks on their wood-cells.

" 2. Sterile flowers grouped together, in spike-like branches, forming
catkins ; fertile flowers surrounded by a cup. They all belong to temperate
climates. Gen. QUERCTJS (oak,) characterized by their fruit, and by the
fact that the female flowers are scattered, and the stameniferous flowers
form bunches. There are more than forty species in the United States.'
Gen. CASTANEA, (chestnut,) allied to the oaks, but the fruit surrounded
entirely by the cup (burr). There are two species in the United States.
Gen. OSTRYA, (hop-hornbeam,) only one species. Gen. CARPINUS, (horn-
beam,) fruit supported by flat leaf. May be distinguished from OSTRYA
by the more prominent ribs, and less deeply marked serratures of the leaves.

" 3. AmentacecB ; both kinds of flowers in catkins. Gen. BETULA,
(birch,) distinguished by the shape of its catkins, which are long and cyl-
indrical, and its winged fruit. Gen. POPULTJS, (poplar,) seeds in a pod,
very minute, and surrounded by down. P. tremuloides (American aspen,)
like the other species, has the leaf-stalk very much compressed, hence the
tremulous motion of the leaf.

" 4. JiKjlandea, fruit with an external soft husk, the nut separating into
two halves. There are two genera of this family in the United States :
JUGLANS. All have compound leaves, that is, each leaf is divided into
leaflets. Two species, black walnut and butternut, the latter distinguished
by the silkiness and whitish color of the underside of the leaf. CARYA,
the nut does not divide so well as in JUGLANS, but the husk is divided and
falls off in pieces, which is not the case in Juglans. At Oeningen, in Swit-
zerland, are found fossil hickories. The trees of the tertiary epoch of
Europe correspond to the species existing at present in this country.

" 5. Oleacece, (the ash family,) leaves like those of hickory, but the large
lateral nerves do not run to the points of the serratures, as in the hickories.
Fruit in bunches, with dry capsules. Flower in the ash, without corolla.

20 LAKE SUPERIOR.

" G. Hamamelidce, (witcli hazel,) named probably from its flowering in
the fall. Fruit in four little nuts. No species of this family in Europe.

" 7. Tiliacece, leaves unsymmetrical. TILIA americana, (bass-wood,)
leaves smooth below.

"8. Acerinece, Gen. ACER, (maple,) leaves in three main lobes, sub-
divided into five.

11 9. Ampelidce, (the grape family,) petals dividing below sooner than at
the apex. Great variety of species in America, but not suitable for making
wine. Three species on Goat Island."

The south shore of Lake Erie is flat and monotonous ; red, crumb-
ling banks, surmounted by a forest broken only by an occasional
log-house. At one time high land visible on the horizon, being a
spur of the Alleghanies.

In spite of all glorification on the score of the " Great Lakes,"
it must be confessed that the Lower Lakes at least are only geo-
graphically or economically great. Any one accustomed to the sight
of the ocean has to keep in mind the square miles of extent,
to preserve his respect for them. Their waves, though dangerous
enough to navigators, have not sufficient swing to carve out a rocky
shore for themselves, or to tumble any rollers along the beach, and
thus the line where land and water meet, in which, as has been
•well said, the interest of a sea-view centres, is as tame as the edge
of a duck-pond. Much of this character is doubtless owing to
the flat prairie country by which they are mostly surrounded.

In the afternoon heavy clouds rolled up from the N.W., and a
squall was evidently approaching. At this time we saw a steamer
in the distance outside of us, with her flag union down. On reach-
ing her we found she had broken her crank. After some clumsy
manoeuvring we got alongside, and her captain persuaded the owner
of our boat, who was on board, to " accommodate " him by towing
him into Cleveland. This kind turn would delay us many hours, and
was by no means necessary for the safety of the boat, since there
were other ports under the lee. Nevertheless, our owner (although,
as we learned, he was to be paid nothing for the trouble,) agreed,
and took them in tow. But shortly after, the squall coming on, it
was found that our machinery would not stand the additional strain,
and she was accordingly cast off to shift for herself. We arrived at

NAKRATIVE. 21

Cleveland at half past ten P. M., and spent there some hours. It is
a thriving town, and a regular stopping place for steamers, but like
almost all the towns on this lake, is without a natural harbor, the
only shelter to vessels being a long pier stretching into the Lake.

Jane 21s£. — Weather fine and warm, with smooth water. Arrived
at Detroit at half past eleven, and left at three P. M. Near
the entrance of Lake St. Clair we were surrounded by numbers of
black terns, {Sterna nigra^) which, at a moderate distance, were
distinguishable from the swallows by which they were accompanied,
only by their superior size. Numbers of slender gauze-winged in-
sects, {Ephemera, Pkryganeaj) with long antennae, and some with two
long filaments projecting behind like the tail feathers of the Tropic
bird about the boat, and on the water. In the St. Clair straits
there were a few ducks, even at this season, though nothing like the
vast flocks to be seen here a little later in the season.

We were sounding constantly through these straits, having on an
average about three feet below the keel in the channel, our boat
drawing seven feet. The shores are low, marshy and aguish, with
woods at a distance, and scattered log-houses. This remarkable
extent of mud-flats, (some twenty miles across,) is covered with
only a foot or two of water in most parts, and even the channel is so
shallow that the larger boats have to discharge a part of their cargo
into lighters while passing it, and are often delayed here many hours.
Even our boat continually touched, as was evident from the clouds
of mud she stirred up. To make and maintain a proper channel for
such a distance, is an undertaking much called for, but not to be
expected of single States, nor is there any one State principally
interested in it. One would hope, therefore, that the General Gov-
ernment may before long do something about it.

The water over these flats is still as green as that of Lake Erie,
and not more turbid. About 10 P. M. we put in to wood, and re-
mained until 7 A. M., taking in sixty-four cords of wood.

June 22cL — We entered Lake Huron about breakfast time ; the
weather calm, and what the sailors call " greasy," the water darker
than in Lake Erie, partly owing, no doubt, to the greater depth of
water, and partly to the cloudy sky. The dark sullen water, and
the unbroken line of forest, retreating on either hand as we issued

22 LAKE SUPERIOR.

from the straits, gave a kind of grim majesty to this lake, by con-
trast to those we had left. Many sea-gulls about. Land in sight
on the left all day, except in crossing Saginaw Bay.

On entering Lake Huron, we began to feel that we were getting
into another region. Canoes of Indians about ; the weather cool
morning and evening, and the vegetation northerly, the pine family
having a decided preponderance in the landscape. We might be
said to have left the summer behind at the St. Clair, for thence-
forth there was hardly a day during some part of which a fire was
not necessary for comfort.

Just before sunset, when the sun was three or four degrees high,
we noticed in the opposite quarter of the heavens, rays of light con-
verging towards a point apparently as much below the horizon, as
the sun was above. It had the appearance of a cloudy sunrise.
We afterwards saw the same thing in the St. Mary's River ; and
it may be remarked, in both cases before rain.*

Jane 23c?. — Arrived at Mackinaw early in the morning, and land-
ed on the wharf in a shower. We had been about eighty hours on
the way from Buffalo, a distance of 663 miles, and we were vexed
to hear that the weekly steamer for the Sault had left the evening
before, and that if we had taken the other boat, which started punc-
tually a couple of hours before us, we should have been in time.

We landed on the little wooden wharf in face of a row of shabby
cabins and stores, with " Indian curiosities " posted up in large
letters to attract the steamboat passengers during the brief stop for
fish. Over their roofs appeared the whitewashed buildings of the
Fort stretching along the ridge. The inhabitants of the place, look-
ing down upon us from all sides, as from the lower benches of a
theatre, soon perceived that we had not departed with the steamer,
and we were soon plied with invitations to the two principal lodging-
houses. From previous experience, I advised the " Mission House,"
and thither we went.

On the beach some Indians were leisurely hauling up their canoes,
or engaged upon their nets, regardless of the rain. The Professor
was soon in the midst of them, and bought white-fish and large pike,

* See a notice of a similar phenomenon by Bory St. Vincent, in Goethe's Farben-
lehre: [Entoptische Farben, cap. XXXI.]

NARRATIVE. 23

which had been taken with nets or lines set the night before. An
excellent breakfast (at which white-fish figured,) and comfortable
rooms, showed that the character of the " Mission House " was still
kept up.

It continued to shower at intervals during the day, but this
did not prevent us from seeing the Natural Bridge, with its re-
gular arch, ninety feet high, rising on the border of the island,
the huge conical rock called the " Sugar Loaf," the Fort, &c. I
do not know whether any of the party visited the cave where Alex-
ander Henry was concealed by his Indian friend during the massacre
of the English — as I did on a former occasion, when, bye the bye, I
found a fragment of a human skull among the rubbish on the floor of
the cave, attesting the correctness of that part of Henry's narrative.

The wet weather was not unfavorable to vegetation, which is luxu-
riant on the island, though the trees, (maple and beech,) are of
small size, this latitude being nearly the northernmost limit of the
latter. The flowers were beautiful ; the twin-flower, (Linncea bor-
ealis^) so fine that I thought it must be another new species ; then
the beautiful yellow ladies' slipper, Lonicera, and Cynoglossum.

The island is of a roundish form, two or three miles in diameter.
On the N.E. the crumbly lime-cliff rises abruptly from the water
to the height of a hundred feet or more ; but on the south there
is a sloping curve of varying width between the bluff and the beach.

The village lies on this slope, a single street of straggling log-
cabins and ill-conditioned frame houses, parallel with the beach, and
some of a better class standing back among gardens at the foot of
the bluff. On the edge of the bluff, which rises abruptly from the
slope at the distance of some three hundred yards from the Lake,
stands the Fort, a miniature Ehrenbreitstein, with a covered way
leading down the face of the bluff.

We were disappointed at finding only three or four lodges of
Indians here. In August and September (the time for distributing
the " presents,") there are generally several hundreds of them on
the island.

Notwithstanding the rain, the Professor, intent on his favorite
science, occupied the morning with a fishing excursion, in which
he was accompanied by several of the party, most of them pro-

tected by -water-proof garments, while he, regardless of wet and
cold, sat soaking in the canoe, enraptured by the variety of the
scaly tribe, described and undescribed, hauled in by their combined
efforts. Not content with this, he as iisual interested and engaged
various inhabitants of the place to supply him with a complete set
of the fishes found here.

With a view of indoctrinating those of us who were altogether
new to ichthyology with some general views on the subject, he com-
menced in the afternoon, scalpel in hand, and a board well covered
with fishes little and big before him, a discussion of their classifica-
tion :

" These fishes present examples of all the four great divisions of the
class. This pike, (Lucioperca americana,} belongs to those having
rough scales and spinous fins. The rays of the first dorsal, and the an-
terior ones of the ventrals and the anal are simple and spinous ; the other
rays are divided at the extremity, and softer. The scales are rough and
remarkably serrate. These are the CTENOIDS. They have five sorts of
fins, viz : the dorsal, caudal and anal, which are placed vertically iu the
median line, and can be raised or depressed, and the ventral and anal,
which are in pairs. In the Ctenoids the ventrals are placed immediately
below the pectorals, though fishes having this arrangement of fins do not all
belong to this division. There are but two families of Ctenoids found in
fresh water : the Percoids and the Cottoids ; the former are characterized
by having teeth on the palatal and intermaxillary bones, but none on the
maxillary. Also by a serrate preoperculum and by the spines on the oper-
culum. Of this family are the genera Perca, Labrax, Pomotis, Oentrar-
chus, &c. The fish before us belongs to the genus Lucioperca. They
have a wide mouth and large conical teeth, like the pickerels, and two dorsals.
There are two species in Europe and two in the United States. This is L.
ameritana; its color is a greenish brown above, with whitish below, and
golden stripes on the sides. On opening the fish we find the heart very far
in front, between the gills, and consisting of a triangular ventricle, a loose
hanging auricle, and a bulbous expansion of the aorta. All the Percoids
have three coacal appendices from the pyloric extremity of the stomach.
These probably take the place of a pancreas. Below is the air-bladder,
which is a rudimentary lung. Above this are the ovaries, which extend from
one extremity of the abdomen to the other. Behind is the kidney, extend-
ing along the spine.

NARRATIVE. 25

This trout belongs to the CYCLOIDS. In this division there are only
two families which have spinous rays in their fins, (the tautog and the
mackerel.) We have before us specimens of two families of Cycloids.

1. Salmonidce. Distinguished by having the intermaxillary and upper
maxillary in one row, which seems to me to indicate the highest rank
in the class of fishes. They all have a second dorsal, of an adipose struc-
ture. The anterior dorsal and the ventrals are in the middle of the body.
Genus Salmo : characterized by teeth on every bone of the mouth and on
the tongue. There is but one genus in the class of fishes that has teeth on
more bones than the salmon. In no genus are the species more difficult to
distinguish. Sixteen species have been described as belonging to Europe,
which I have been obliged to reduce to seven. The same species presents
great variety of appearance, owing to difference of sex, of season, food, color
of the water in which they live, &c. In this country I have examined two
species, the brook trout, (£. fontinalis,) the spawning male of which has
been improperly separated as S. erythrogaster ; and the present species, the
Mackinaw trout, S. amethystus of Mitchill. Dekay has described a variety
of this species, as S. affinis. In this species the appendices pylorici before
spoken of are very numerous. The small intestine arises from the lower
extremity of the stomach, and curves only twice throughout its length. The
gall-bladder is very large : the liver forms one flat mass ; the ovaries and
kidney extend along the whole spine. All this family spawn in the autumn.

"(2.) Cyprinidce. Like the salmons they have the ventral and dorsal fins
in the middle of the body, but no adipose dorsal. Branchiostegal rays,
three. Upper maxillary forming another arch behind the intermaxillary.
Teeth only on the pharyngeal bone behind the gills, at the entrance of the
oesophagus. No pyloric appendices. Intestine long and thin, as in all her-
bivorous fishes. Air-bladder transversely divided into two lobes, communi-
cating by a tube with the intestinal canal..

" This family is the most difficult one among all fishes. As yet there is
no satisfactory principle of classification for them. I have studied them so
attentively that I can distinguish the European species by a single scale ;
but this not from any definite character, but rather by a kind of instinct.
Prof. Valenciennes, a most learned ichthyologist, has lately published a vol-
ume on this family, in which he distinguishes so many species, and on such
minute characters, that I think it now almost impossible to determine the
species, until all are well figured.

" Here are specimens of two genera : (a) Leuciscus, with thin lips ; only
one species here, an undescribed one characterized by a brownish stripe above
the lateral line. (6) Catostomus, with very thick lips and prominent snout."

June 24th. — Rather than wait here a week for the next steamer,
we engaged a Mackinaw boat and some Canadians to take us to the
Sault. These boats are a cross between a dory and a mud-scow,
having something of the shape of the former and something of the
clumsiness of the latter. Our craft was to be ready early in the
morning, but it was only by dint of scolding that we finally got off
at 10 o'clock. A very light breeze from the southward made suf-
ficient excuse to our four lazy oarsmen and lazy skipper for spreading
a great square sail and sprit-sail, and lying on their oars. Unless it
was dead calm, not a stroke would they row.

At about 1 o'clock, Mackinaw still plainly visible at a very moder-
ate distance to the southward, we stopped to lunch at Goose Island,
a narrow ridge of rough, angular pebbles, about half a mile long,
covered with thick bushes and stunted trees, among which the prin-
cipal were arbor-vitae and various species of cornus. It passed
through my mind whether this could be the lie aux Outardes, where
Henry parted with his Indian friend. It is difficult to say what
bird of this region could have reminded the French colonists of a
bustard.

Getting off again we continued at rather a better rate (the wind
being now fortunately ahead) until twilight, when our steersman
said it was time to look out for a camp, and proposed landing us on
a little island near the western shore of the strait. The more ardent
naturalists of the party, however, seeing a sand-beach, (capital
hunting-ground for Coleoptera,) backed by a grassy bank among
the trees, were anxious to land there, but this was promptly
opposed by the whole of our native ship's-company, who urged
that we should be devoured by " les mouclies." This suggestion
seeming reasonable, it was arranged that those who wished it
should be landed on the beach, while the rest proceeded to encamp
and get supper ready on the island. This was done ; but hardly had
we disembarked and lighted a fire, when cries were heard from the
main land, and on looking round we saw our friends, some with their
heads bound up in handkerchiefs, others beating the air with branches
of trees ; all vociferating to us to " Send the boat !" and on the
whole, manifesting the most unmistakable symptoms of musquitoes,
which were abundantly confirmed when they joined us.

NARRATIVE. 27

Our island was a mass of large irregular stones, about a quarter of
a mile long, with a narrow ridge covered with long grass and arbor-vi-
tses, many of them dead, and (particularly on the west,) hung over
with pendant lichen (Usnea). Here, (after some trouble from not
having brought tent-poles, which had now to be cut,) we pitched four
tents, for only two of which was there any room on the grass, the
others looking out for the smallest stones. However supper and
three blazing fires soon settled all clown into a comfortable state, and
before long the white tents and the ghost-like trees with their hoary
drapery were the only upright objects to reflect the light of the fires,
and the long melancholy notes of some neighboring loons (a sign of
bad weather, they say,) the only sounds to be heard. As my lot
was cast upon the stones, I took the precaution of thatching them
with some armfuls of usnea, which with a couple of blankets made
an excellent bed.

June 25th. — Our island was only about thirty miles from Macki-
naw, and so, as it behoved us, we were off by half past four o'clock this
morning, with the wind aft, to try to make up for lost time. Our
course lay along the American shore of the strait, amid innumerable
islands and islets, generally low and wooded with venerable lichenous
arbor-vitees. The shore also was uniformly low, and covered with a
forest which reminded me of the lower summits of the White
Mountains.

We stopped to breakfast just beyond the light-house at the De-
tour, at the log-house of some lime-burners, a tavern moreover,
rejoicing in the name of "the saloon," where we experimented
upon tea with maple-sugar, and bread of the place, somewhat like
sweetened plaster-of-Paris. Drurnmond Island, interesting from its
fossils, we were obliged to pass without stopping.

By noon the wind had got so high that we thought prudent to
make a lee under a point on St. Joseph's Island. As we landed, a
rather rough-looking, unshaven personage in shirt-sleeves walked up
and invited us to his house, which was close at hand. We found
his walls lined with books ; Shakspeare, Scott, Hemans, &c.,
caught my eye as I passed near the shelves, forming a puzzling con-
trast with the rude appearance of the dwelling. A very few
moments sufficed to show a similar contrast in our host himself. He

knew Prof. Agassiz by reputation, had read the reports of his lectures
in the newspapers, and evinced a warm interest in the objects of our
excursion. When he found out who the Professor was, he produced
a specimen in spirits of the rare gar-pike of Lake Huron, and insisted
upon his accepting it, and afterwards sent him various valuable spec-
imens. His conversation, eager and discursive, running over Politics,
Science and Literature, was that of an intelligent and well-read
man, who kept up, by books and newspapers, an acquaintance with
the leading topics of the day, but seldom had an opportunity of
discussing them with persons similarly interested. He turned out to
be an ex-Major in the British army, and he showed us a portrait of
himself in full regimentals, remarking with a smile that he had once
been noted as the best-dressed man of his regiment. Whilst in the
service he had travelled over Europe, seen what was best worth
seeing, and become acquainted with the principal modern languages,
particularly Italian, which he read here in the wilderness with delight.
In company with a friend he had purchased the entire island of St.
Joseph's and devoted himself to farming, bringing up his children to
support themselves by the sweat of their brow. He said it would be
time enough to give them a literary or professional education when
they manifested a disposition for it, for he did not approve of the
indiscriminate training of all for what comparatively' few have
any real talent for. He was preparing them, he said, to be
American citizens, for he thought the Canadas would form a part
of the United States within three years at farthest ; and though he for
his part was a loyal subject of her Majesty, and would fight to protect
her dominions if it came to that — yet he had no objections to his
children being republicans.

After chatting several hours with the Major, and discussing an
excellent white-fish which he placed before us, the wind having
meantime moderated, we continued our course. St. Joseph's,
according to the Major, forms a triangle, of which the two longest
sides measure twelve and twenty miles. The climate he described
as temperate, being influenced probably by the great mass of flowing
water by which the island is surrounded. His custom was to work
throughout the winter in his shirt sleeves ; he did not remember to
have seen the thermometer lower than — 10° Fah., and that only for
very short periods. The soil excellent, except near the shores.

NARRATIVE. 29

Passing the end of the island we saw two solitary chimneys, the
remains of the fort that formerly stood here. Our course lay
among small . islands, reminding one of the little wooded islets of
Lake George, with a brilliant background of sunset sky. We noticed
the same appearance in the east, spoken of June 22nd. The twilight
continuing late, we pushed on until about ten o'clock, when our men
proposed to land on a small rocky island, but they being alarmed at
a discovery (probably imaginary) of snakes among the rocks, and
we for our part not finding room enough among the stones to pitch
a tent, we continued our course to another island which bears^ the
name of " Campement des matelots." Here it was voted too late to
pitch tents, so we rolled ourselves in our blankets, some on shore
and some in the boat, taking care to include our heads, for the mus-
quitoes had roused themselves and were making active preparations
to receive us.

June 2Qth. — The musquitoes of the night before must have been
merely those who occupied the spots where we lay down, for when in
the morning, being awakened by sundry energetic exclamations in
my neighborhood, I extricated my head from the blanket and looked
about me, my first impression was wonder, at the swarms that sur-
rounded the heads of my companions. Having fortunately a mus-
quito-veil in my pocket I was soon a disinterested spectator of their
torments. It was with some difficulty that the necessary arrange-
ments for embarking (with no thought of breakfast) were completed,
and it was more than an hour after we left the place before with all
our exertions we could get the boat rid of them.

Soon afterwards it began to rain. Our course lay up the boat-chan-
nel, (twelve miles shorter than the main passage,) over mud-flats
covered with only a few feet of water, the banks on either side flat
and covered with a monotonous forest which in one place was burnt,
and for miles a tedious succession of blackened trunks. We crowded
together in the middle of the boat and covered ourselves as well as
we could with tarpaulins and India rubber cloaks, the importance of
which rose considerably in the general estimation. This muddy
expanse of the river or strait, goes by the name of Mud Lake. It
resembles Lake St. Clair on a smaller scale, being eight or ten miles
wide. Here, as we were afterwards told, is found a great abundance
and variety of fishes, and also the salamander which the Indians call

30 LAKE SUPERIOR.

the " walking fish" (Menobranchus'), and which even to them is a
great curiosity. At last we reached the Lower Rapids, where with
all the exertion of our men we for some time made little progress.
Soon a cabin or two made its appearance ; then we saw the palisades
of Fort Brady, and at noon arrived at the wharf, where even the
rain did not prevent a considerable concourse of the idle population.
Carts drove down into the water for our luggage, and at length our
drenched state was relieved by the comfortable accommodations of
the " St. Mary's Hotel."

CHAPTER II.

THE SAULT TO MICHIPICOTIN.

June 2,7th. — The Sault de St. Marie, on the American side, is a
long straggling village, extending in all some two or three miles,
if we reckon from the outposts of scattered log-huts. The main
part of it, however, is concentrated on a street running from the
Fort (which stands on a slight eminence over the river,) about a
quarter of a mile along the water, with some back lanes leading up
the gradual slope, rising perhaps half a mile from the river. Be-
hind this again is an evergreen swamp, from which a rocky wooded
bluff rises somewhat abruptly to the height of a hundred feet or
thereabouts.

The population is so floating in its character that it is difficult to
estimate ; some stated it at about three hundred on the average,
consisting of half-breed voyageurs, miners waiting for employment,
traders, ancl a few Indians. The chaplain at the Fort, however, esti-
mated the number of inhabitants on both sides of the river at one
thousand, of whom the majority belong to the American side.

The most striking feature of the place is the number of dram-
shops and bowling-alleys. Standing in front of one of the hotels I
counted seven buildings where liquor was sold, besides the larger
" stores," where this was only one article among others. The
roar of bowling alleys and the click of billiard balls are heard
from morning until late at night. The whole aspect is that of a
western village on a fourth of July afternoon. Nobody seems to be
at home, but all out on a spree, or going a fishing or bowling.
There are no symptoms of agriculture or manufactures ; traders
enough, but they are chatting at their doors or walking about from
one shop to another. The wide platforms in front of the two large
taverns are occupied by leisurely people, with their chairs tilted

32 LAKE SUPERIOR.

back, and cigars in their mouths. Nobody is busy but the bar-
keepers, and no one seems to know what he is going to do next.

The cause, probably, may be in part the facilities for smuggling
brandy from the Canadian side of the river, where it is cheaper than
on ours. But the mischief lies chiefly in the unsettled state of things,
the irregularity of employment and wages of labor. Money is not
earned and spent from day to day, at home, but comes in lumps,
and seasons of labor are followed by intervals of idleness. In short,
the life of most of the inhabitants is essentially that of sailors, and
brings accordingly the reckless character and the vices of that class.

Something also is due to the admixture of Indian blood, which has
a fatal proneness to liquor. Whilst we were here a number of Indians
arrived with the son of a chief, from Fort William, and after parad-
ing about the town with an American flag, speechifying and offering
the pipe at all the grog-shops to beg for liquor, they dispersed and
devoted themselves to drinking and playing at bowls. In the even-
ing, two of us passing one of the bowling-alleys, saw in front of it,
lying on a heap of shavings, a dark object which proved to be the
chief's son, extended at full length, dead drunk, with several Indians
endeavoring to get him home. The only sign of life he gave was a
feeble muttering in Indian, copiously interspersed with the English
curse ; another instance of the naturalization of John Bull's national
imprecation in a foreign tongue. It is said the Indians have no
oath in their own language. Finding it impossible to make him
walk, they squatted around him on their haunches and remained still
for some time, apparently considering what to do. They were all
perfectly sober and evidently greatly troubled at the state of their
leader. At length, seeing us watching them, they came up and
stood staring with their faces close to ours, but without speaking.
We did not know exactly what they were at, but my companion by
signs explained to them that they should take up the drunken man
by the legs and arms and carry him home. The idea struck them
as a good one, for they immediately " how, howed," set about it,
and bore him off, one to each leg and arm.

The river opposite the village is about a mile wide. Just above
are the Upper Rapids, which give the name to the place, nearly
three-fourths of a mile in length. There is no very great vertical

descent,* but the stream is much compressed and moreover very
shallow, whence the great rapidity of the current at this spot. On
the opposite bank is a thin, -straggling village, and a large building
belonging to the Hudson's Bay Company.

Our explorations of the neighborhood showed a great abun-
dance of birds for the season. Prof. Agassiz as usual had
got all the fishes of the neighborhood about him ; among others
several specimens of the gar-pike of Lake Huron, dried or in spirits,
were presented to him by the various coadjutors whom he had
interested in his favor. One of the most zealous of these was a fish-
erman whom he had captivated by a distinction (at first stoutly and
confidently combatted) between two closely-resembling species. In
the evening he unrolled his blackboard and gave us the following
account of them :

" The gar-pike is the only living representative of a family of fishes
which were the only ones existing during the deposition of the coal and other
ancient deposits. At present it occurs only in the United States. The spe-
cies of South Carolina was described by Linnaeus as Esox osseus, from a
specimen sent to him by Dr. Garden. But it is not an Esox, though it has
the peculiar backward dorsal of that genus. It differs in the arrangement
of the teeth, which in Esox are seated on the palatal bones and the vomer,
but in this genus, Lepidosteus, on the maxillary and all other bones which
form the roof of the mouth. Moreover, the snout of the latter is much longer,
the upper jaw bones being divided into ten or twelve distinct pieces. The
intermaxillary is a small bone pierced with two holes for the admission of the
two anterior projecting teeth of the lower jaw. In Esox the scales are
rounded and composed of layers of horny substance, and overlap each other.
In Lepidosteus the scales are square and overlap only very slightly. Each
scale is composed of two substances ; first, a lower layer of bone, forming
that part of the scale which is covered by the next ; second, enamel, like that
of teeth. The scales are also hooked together; a groove in each, with a
hook from the next fitting into it. Nothing of this kind occurs in other
fishes of the present day. From these peculiarities I have named this
family the GANOIDS. Their vertebras are not articulated together as those

* According to Bayfield the total descent is twenty-two and one-half feet, but
this probably includes both the Upper and Lower Rapids, as the whole difference of
level between Lake Superior and Lake Huron, in a distance of forty miles, is only
thirty-two feet.—Bouchette's British, Dom. in N. America, I., 128.

34 LAKE SUPERIOR.

of other fishes, but unite by a ball-and-socket joint, as in reptiles. The
scales also resemble in some particulars those of the Crocodilean reptiles,
which immediately succeeded the fossil Ganoids, during whose epoch no
reptiles existed. The embryology of the gar-pike, of which nothing as yet
is known, would be an exceedingly interesting subject of investigation, since
it is a general law that the embryo of the animals now living resembles the
most ancient representatives of the same family. As probably connected
with the preservation of this ancient family of fishes in this country, may
be mentioned the fact that there was an extensive continent formed in North
America at a time when all the rest of the earth was under water. Thus
physical conditions have been more unaltered here than elsewhere.

" The white-fish, ( Coregonus albus,) has all the characters of the salmons,
but no teeth. Among those I obtained to-day, is a new species, cha-
racterized by a smaller mouth and more rounded jaw. To the same family
belongs the lake " herring," which is no herring at all. This species has
a projecting lower jaw and is undescribed. Here is a little fish which on
hasty examination would seem to belong to the salmons, but has a project-
ing upper jaw, and teeth on the intermaxillary, the upper maxillary
forming another arch behind, without teeth. It has pectinated scales, like
the perch. It is a new genus, allied to the family of Characini of
Miiller. Fossil fishes of this family occur in great numbers in the creta-
ceous period ; they are the first of the osseous fishes. This again is an in-
stance similar to that of the Lepidosteus. The fish before us presents a
curious combination of the characters of the Cycloids and Ctenoids. Here
is a fish belonging to the CyprinidcB, but characterized by thick lips and a
projecting upper jaw, whence I propose to call it Rhinichthys marmoratus.

" This fish, one familiar with the fishes of Massachusetts would suppose to
be a yellow perch, but it differs in wanting the tubercles on the head and oper-
culum. It is Perca acuta Cuv. In the tertiary beds are found Percoids,
with thirteen rays in the anterior dorsal ; this is also the case in the North
American species. Again the variety of minnows found in this country
has a parallel in the tertiary epoch."

June 28th. — To-day we made our first acquaintance with the
genuine black fly, a little insect resembling the common house-fly,
but darker on the back, with white spots on the legs, and two-thirds
as large, being about two lines in length. They are much quicker in
their motions, and much more persevering in their attacks, than the
musquito, forcing their way into any crevice, for instance between

NARRATIVE. 35

the glove and the coat-sleeve. On the other hand, they are easily
killed, as they stick to their prey like bull-dogs.

June 22th. — Among the birds here, the most abundant is the
white-throated sparrow, (Fringilla penmylvanica^ evidently breed-
ing in great numbers in the swamp, for from the top of nearly
every dead tree a male bird of this species was pouring forth
his loud, striking note, something like the opening notes of the
European nightingale. The females were not to be seen, and were
doubtless sitting. I found the nest and new-laid eggs of the song-
sparrow, but could not discover those of the penmylvanica. In the
evening the Professor made the following remarks on the classifica-
tion of birds :

"Animals have usually been classed merely according to the characters
of the adult. In some instances, however, the importance of an examina-
tion of the embryonic state also has already been acknowledged by natural-
ists. For example, the barnacle, though in fact a crustacean, has in the
adult state so much the appearance of a mollusk, that its true relation
could hardly be recognized without the- investigation of the embryo, which
has all the aspect of the ordinary crustaceans. Hitherto embryology has
been applied principally to the study of functions and organs, and not of
classification, but I think it of the highest importance to the right under-
standing of the affinities of all animals.

' Birds are at present classed according to the form of the feet and bill.
They form a very distinct group in the animal kingdom, all having wings,
naked bills, and the same general form of feet. Yet no class has puzzled
naturalists more.

" Great weight has been given to the form of the toes. In one great
group, (Palmipedes,) at least three of the toes are united by a web (four in the
pelican and gannet,) throughout their whole length. In all other birds the
toes are free, though in some the upper joints are united.

' The form of the claws has also been considered of great importance. In
birds of prey an agreement in the form of the claws is accompanied by a
resemblance in the shape of the bill. In others, however, this is not the case ;
thus the parrots, with crooked bills, and the woodpeckers with straight bills,
have been united as climbers. Again, the passerines, classed together from
the shape of the bill, agree very well in other respects ; but in the water-
birds, species of very various characters have been brought together.

' Taking all these things together, ornithologists have very generally agreed

36 LAKE SUPERIOR.

on fpur or five great divisions, though with some differences. Thus the
waders, or those birds having the tarsus and a space above it naked, are
put in one group by some, and by others made into two. The arrangement
of the water birds now most generally admitted is : Palmipedes : with the
feet united, except in one group, (the grebes, &c.) This division, I incline
to think, is made on an insufficient consideration of their true affinities.
Grallatores : with three toes before, and one behind. The gallinaceous
birds form a very natural group, having the upper jaw arched, and feet like
those of the grallatores, but with short and curved claws The climbers have
two toes before and two behind, of which one may generally be moved in
either direction. Sometimes there is only a trace of this arrangement, in a
closer union of two of the toes with each other than with the rest. The
passerines have curved claws, or sometimes the hind-claw is straight ; three
toes before and one behind. Some make three groups of them, bring-
ing together those with flattened bills, (Insectivora ;) those with conical
bills, (Granivora,) and those with the upper mandible much stronger than
the lower, (Omnivora.) Some again separate from these the swallows,
pigeons, &c.

" The toes in all birds have the same number of joints. The hind toe
always consists of a single joint, the inner toe of two, the middle of three,
and the outer of four. This arrangement is important in distinguishing the '
fossil tracks of birds from those of other animals, it being peculiar to them.

" In examining birds within the egg, I have recently found some charac-
ters to be less important than has been supposed. Thus the foot of the
embryo robin is webbed, like that of the adult duck ; so also in the sparrow,
swallow, summer-yellow-bird, and others, in all of which the adult has divided
toes. The bill also is crooked and the point of the upper mandible projecting,
as in the adult form of birds of prey. These latter, then, it would seem,
should be brought down from the high place assigned to them on account
of their voracious and rapacious habits, as if these would entitle an animal
to a higher rank. For the resemblance of an adult animal to the embryo
of another species, indicates a lower rank in the former.* Probably the true
classification of birds would include various series, each embracing represen-
tatives of all the various types now admitted as distinct."

Mr. Ballenden, of the Hudson's Bay Co., to whom the Professor
had letters, paid him a visit to-day, and showed the most obliging

eller, and afterwards in a pamphlet form by the same publishers.

readiness to forward his plans, giving him letters to the gentlemen
in charge of the various posts on the lake, which were highly ser-
viceable to us.

Dr. C. T. Jackson and the gentlemen engaged with him in the
geological survey of the copper region of the south shore of Lake
Superior, also arrived to-day, and his assistant, Mr. Foster, gave the
Prof, some valuable information, particularly concerning Neepigon
Bay, which he had visited.

Mr. McLeod, of the Sault, lent to the Professor Bayfield's large
map of the Lake, (which we had not been able to procure,) enriched
with manuscript notes, and gave him the results of various geologi-
cal excursions on the lake.

June, 30th. — Rainy. Nevertheless, our preparations being made,
we decided to start. It was necessary to convey our multifarious
luggage to the upper end of the portage, above the rapids, a distance
of about two-thirds of a mile. Walking thither in the rain, over a
road made across the swamp, the surface of which is strewed with
bowlders of various sizes, we found a collection of warehouses and a
•few log-cabins, just at the commencement of the rapids. Here our
boats were moored at a wharf at the extremity of which was a huge
crane for unloading copper ore. Here also lay at anchor several
schooners, and a propeller that runs along the south shore, and
occasionally crosses to Fort William.

Our boats were three in number ; one large Mackinaw boat and
two canoes of about four fathoms' length. One of these canoes was
kindly lent to us by Prof. James Hall, of Albany, the other we hired ;
the boat we had been obliged to buy, giving eighty dollars for it. It
proved a considerable hindrance to speed, being always behind, ex-
cept when the wind was aft and fresh. Our luggage, however, with the
collections of specimens and the apparatus for collecting, could not be
carried in canoes without uncomfortably loading them. From my own
subsequent experience I should say that what is called a " five-man-
boat," is the craft best adapted for such an occasion as ours, and
this opinion was confirmed by a gentleman at the Sault who had
tried the experiment. The canoes were precisely what one sees
from Maine to Michigan, birch-bark stretched by two layers of thin,
flat, wooden ribs, one transverse, the other longitudinal, placed close
together, with a strip of wood round the gunnel, and the whole

38 LAKE SUPERIOR.

sewed with pine-roots. It is said that after the materials are cut out
and fitted, two men to put them together, with six women to sew,
can make two seven-fathom canoes in two days. While on the lake
the canoes are not usually paddled, but rowed, the same number of
men exerting greater force with oars than with paddles. By doub-
ling the number of men, putting two on a seat, more of course can
be accomplished with paddles. The gunnel of a canoe is too slight
to allow of the cutting of rowlocks, or the insertion of thole-pins : so
a fiat strip from a tree, with a branch projecting at right angles, is
nailed to the gunnel, and a loop of raw hide attached, through
which the oar is passed.

Our boats were stowed as follows : On the bottom were laid set-
ting-poles and a spare paddle or two, (to prevent the inexperienced
from putting their boot-heels through the birch-bark,) and over these,
in the after part, a tent was folded. This formed the quarter-deck
for the bourgeois, (as they called us,) and across it was laid the
bedding, which had previously been made up into bolster-like pack-
ages, covered with buifalo-robes, or with the matting of the country,
a very neat fabric of some fine reed which the Indians call paquah.
These bolsters served for our seats, and around them were disposed
other articles of a soft nature, to form backs or even pillows to
our sitting couches. The rest of the luggage was skilfully distrib-
uted in other parts of the canoe, leaving room for the oarsmen
to sit, on boards suspended by cords from the gunnel, and a
place in the stern for the steersman. The cooking utensils were
usually disposed in the bow, with a box of gum for mending the
canoe and a roll or two of bark by way of ship-timber. Our canoe
was distinguished by a frying-pan rising erect over the prow as
figure-head, an importance very justly conferred on the culinary
art in this wilderness, where nature provides nothing that can be
eaten raw except blueberries.

The voyageurs (some ten or twelve in number,) Avere mostly half-
breeds, with a few Canadian French and one or two Indians. All
except the Indians spoke French, and most of them more or less
English, but there were only two who spoke English as well as they
did French. The half-breeds were in general not much if at all
lighter in complexion than the Indians, but their features were more or
less Caucasian, and the hair inclining sometimes to brown. They were

NARRATIVE. 39

rather under medium height, but well made, particularly the chest and
neck well-developed. The Indians were Ojibwas (ojib-wah), and had
the physical peculiarities of their tribe, viz. : a straighter nose, rather
greater fulness of the face, and less projecting cheek-bones, than the
Western Indians. But I was most struck with the Irish appearance
of the Canadians, and though I ascertained that they had no Irish
blood in their veins, yet the notion often recurred during the trip, and
I found myself several times surprised at missing the brogue. They
were blue-eyed, with flaxen hair, a rather low and square head, and
high-pitched voice. This resemblance, which also struck others of
the party, is interesting as showing perhaps che persistance of blood
and race. It was not until afterwards that I was informed that the
French of Canada are Bretons and Normands by origin ; thus coming
from that part of France in which, whether as most remote from in-
vaders, or from having been recruited from the British Isles, the
Celtic blood is best preserved. I do not know whether the Celtic
features are so noticeable at this day in that part of France, but no
one would have ever taken these men for Frenchmen.

Our preparations occupied some time ; finally, just as we were
about to start, it was suggested and on short consultation decided
that we must have an additional canoe ; those provided proving insuffi-
cient to hold us all comfortably. Two of the party accordingly
remained behind to attend to this matter, and we got under weigh.

We had but three in the canoe besides the boatmen, which gave
us an advantage over the others, so that we immediately took the
lead, and soon ran the other boats out of sight. The rain ceased, but
the weather was still unsettled, and the wind, strong down the
river, much retarding our progress. Our men had a hard pull of it,
yet they kept up an unceasing chatter in Ojibwa, (which sounded
occasionally much like Platt-Deutsch,) interspersed with peals of
laughter. About five o'clock we reached the Pointe-aux-Pins, about
six miles from the Sault, and as the wind had become very strong,
and the other boats were far behind, we decided to wait for them.

The Point is a mass of sand and gravel, mingled with large
stones ; towards the main land are a few pitch-pines and willows ;
the ground covered with moss and low bushes, and a few strawber-
ries. Some flocks of pigeons were whirling about, at times dashing
down to the ground, and then rising high in the air ; a couple of these

were shot, as well as a young creek-sheldrake, (Mergus cucullatus^)
from a small flock in a creek emptying into the river. On returning
to the neighborhood of the boat, we found a fire lighted and prepara-
tions making, under the superintendence of Henry, the steersman, for
getting a supper from a ham and some flour which had been provi-
dently stowed in our canoe. The process of frying the ham, and
roasting the birds on a spit stuck in the ground, was neither new nor
interesting to me otherwise than as conducive to supper. But the
process of making bread with mere flour, water, salt, and a frying-
pan, excited my curiosity. Nothing to my knowledge was put in to
make the bread me, neither had anything been provided by us for
that purpose, yet the dough, after having been kneaded for a long
time, pressed down into the frying-pan and toasted before the fire,
turned out excellent bread, perfectly light and well-tasted. By what
mystery the fermentation was accomplished or gotten over, I le&ve
to the initiated to make out. Perhaps the vigorous and long-con-
tinued kneading may have supplied the place of yeast ; at all events,
some of the party, whose cooks were more sparing of their labor than
ours, used to have heavy bread, a misfortune that never befell us.

Shortly before dark the other canoe arrived, and we learned that
the bateau had been driven back by the force of the wind, and had
put in for the Canada shore.

We were now established for the night. There was nothing very
cheery about the aspect of the Pointe-aux-Pins ; - - a desolate mass of
sand, with the tent standing out against the bleak sky, backed by a
few stunted willows, the river a couple of hundred yards in front,
and a horizon of forest beyond.

A bleak, desert situation, so exposed to the wind that we had to
carry a guy far to windward, attached to the peak of the tent, to pre-
vent it from being blown over. No vestige of human habitation in
sight, and no living thing, except the little squads of pigeons scud-
ding before the wind to their roosting place across the river. Yet I
felt as I stood before the camp-fire, an unusual and unaccountable
exhilaration, an outburst, perhaps, of that Indian nature that delights
in exposure, in novel modes of life, and in going where nobody else
goes. We slept comfortably on the sand, which makes a good bed,
easily adapting itself to the shape of the body, with the drawback
however of getting into one's hair and blankets.

NARRATIVE. 41

July 1st. — Early this morning our companions in the bateau
joined us. They had run some danger of swamping, the day before,
and had been forced to put in on the Canada side, not much above the
Sault, where they found good quarters on board a steamboat that
had been seized for smuggling and laid up in ordinary by the Cana-
dian government. After breakfast we started in company and got
up to Gros-Cap, about fifteen miles, where we halted, there being no
good camping-ground for some distance beyond.

From the Pointe-aux-Pins to the mouth of the river, some four or
five miles, the width of the stream varies from one to two miles.
Here it enlarges rather suddenly, so that Gros-Cap and Point-Iro-
quois, the Pillars of Hercules of Lake Superior, as some one calls them,
are six or seven miles apart. This is the true entrance of the lake.
The shore continues low and marshy for some distance beyond ; then
the high land of the Cape comes in sight, stretching across at right
angles with the course of the river, and soon the scenery in the im-
mediate neighborhood also assumes the proper character of the lake.
I was struck with the similarity to some portions of our sea-coast,
for instance, in the neighborhood of Gloucester in Massachusetts,
or Cape Elizabeth, near Portland. Rocky points, covered with
vegetation, rising abruptly from deep water, alternate with pebble
beaches ; back of this, the land slopes gradually upward, densely
covered with white pine, canoe-birch and aspen, to the foot of
the cliff, which rises steeply to the height of seven hundred feet,
showing vertical faces of bare rock, and crowned on the top with

evergreens.

We encamped early in the day in a narrow cove, formed by a
point of low rocks, running almost parallel to the shore. Here
we encamped among large aspens, and thickets of the beautiful
white-flowering raspberry of the lakes, (Hubiis Nutkanus.~) Our
friends joined us from the Sault with a large seven-fathom canoe
pulling three oars, which was christened the " Dancing Feather."

After dinner, two of us set oif for the top of the cliff. The slope
forming the border of the lake in this spot seems to be merely the
debris fallen from the face of the cliff, which rises so abruptly that
we were obliged to skirt along its base for some distance before we
found a practicable ascent in a gully in the face of the rock, and here

even only by help of the trees. Climbing along the ledges and from
one trunk to another, we at length reached the top, a mass of rock,
intermingled with spruce trees. The wind blew fresh and we were
in hopes to be free from the flies and musquitoes, which were rather
troublesome below. The result showed that we had reasoned cor-
rectly as to the musquitoes, but not at all as to the flies, who, as we
now learned for the first time, by actual experience, affect high and
dry places. They surrounded us in such swarms that it was impos-
sible to remain quiet for a moment ; brushing them away with
branches was of no use, and even a musquito veil proved no
protection. " The meshes being rather larger than their bodies,
they alighted for a moment upon it, and then deliberately walked
through. When the wind blew very hard they would make a lee for
an instant, and then reappear in clouds. On arriving at the camp,
we were speckled with blood, particularly about the forehead and
back of the ears. Our faces looked as if charges of dust shot had
been fired into them, each sting leaving ,a bloody spot.

It was discovered this evening that some things had been left be-
hind, and our short experience had already taught the need of some
others, so two of the party volunteered to go back in a light canoe
to fetch them from the Sault.

July 2c?. — It was thick and rainy to-day, so we did not leave our
camp. In our immediate neighborhood were several lodges of In-
dians ; " gens du Lac" as our men called them, from whom we
bought trout. They had the general features of the Ojibwas, but
ragged and dirty. They subsist by fishing, and seem to bear out
the remark that among savage nations, the fishing tribes are the
most degraded. Their lodges were composed of a dome-shaped frame-
work of poles, over which were laid pieces of birch bark. We often
afterwards met with these frames at our encampments, but without
the bark covering, which they probably cany off with them. They
are perpetually shifting their quarters, for no reason but mere rest-
lessness, often leaving a prosperous fishery to go off to some other
place where the prospects are entirely uncertain.

During our stay at this place, finding it inconvenient to eat our
meals all together, we separated into four messes, each having its
boat and its tent, and making its separate camp-fire and cuisine.

NARRATIVE. 43

This arrangement is indeed on many accounts an advisable one.
Otherwise there is a great deal of squabbling among the men, for
each is willing to look out for his own canoe and bourgeois, but not
for the rest, and they try to shift the labor from one to the other.
Except that we usually encamped in the same neighborhood at night,
and were sometimes within hail of each other during the day, we
might henceforward be considered as four separate parties.

In our canoe everything settled down after this into a very
methodical routine, which I may as well describe here. We were
provided in all respects with an independent equipment, embrac-
ing provisions for a day or two, viz., salt pork, ham, potatoes, peas,
beans, flour, hard bread, rice, sugar, butter, coffee, tea, pickles and
condiments. When we landed in the evening, as soon as the canoe
was unladen and hauled up, two of the men proceeded to pitch the tent,
while the other collected wood, made a fire, put on the tea-kettle, and
brought up the mess-chest, which contained tin plates, knives and
forks, &c., and also in bottles and tin cases those of our stores that
would be injured by moisture. Then they devoted themselves to
preparing supper. One kneaded dough in a large tin pan ; another
fried or roasted the fish, if we had any, or the pork or ham, if fish
was wanting. A large camp-kettle, suspended by a withe from a
tripod of sticks, over the fire, contained a piece of pork, and dump-
lings, which the men preferred for themselves, or occasionally a rice
pudding for us. When all was ready, an India-rubber cloth (which
served to protect the luggage, and on occasion for a sail,) was
spread on the ground, and the dishes arrayed upon it. Around
this we reclined in the classical fashion, and Henry stood by to serve
coffee and fetch anything that might be wanted. As to provisions,
if I were consulted about the outfit of such a party as ours, I should
recommend a full supply of rice and sugar. Maple sugar (which
can usually be had in these regions,) is as good as any, for one's taste
becomes unsophisticated in the woods ; the rice, I may observe, must
be boiled in a bag, and not loose in the camp-kettle, as the Professor's
man did it one day, when it came out in the shape of mutton broth
without the mutton. Salt pork is very well where one goes a-foot,
or paddles his own canoe, but in a life of so little exertion as ours,
the system cannot dispose of so much carbon, and rejects it accord-

ingly. For the same reason, perhaps, I found that I not only did
not miss the milk in the coffee, but could not drink it when it was
sent to us at the trading posts. Potatoes would no doubt be a good
thing, but our men did not know how to cook them. Before we
started, the question being raised as to the relative quantities of tea
and coffee to be bought, the most thought they should drink very
little coffee, but depend upon tea. On the contrary, however, I
believe there was hardly a cup of tea drank on our whole tour, (ex-
cept by the men,) when coffee could be had. The truth is, that tea
is very refreshing after a hard day's work, and it was prized accord-
ingly by the men, but we did not take exercise enough to care for it.
After we had done our meal, the men took theirs. At dark
Henry brought us a candle, and then he and the other men turned
in, all lying close together, sometimes entirely in the open air,
sometimes with their heads under the canoe, or if it rained they
made a kind of tent with the India-rubber cloth. They had each a
very comfortable supply of blankets, &c., and somewhat to my sur-
prise each was provided with a pillow. Our own bedding consisted,
in my case, for instance, of a buffalo robe by way of mattress, and two
very heavy Mackinaw blankets, which I had brought from Boston,
as they are dearer and of inferior quality at the Sault. Others had
the same, or an equivalent. I have heard of travellers who brought
blow-up mattresses of India-rubber, and if these things are managea-
ble, I should recommend their being taken, as we were often incon-
venienced by the large angular stones of the beaches on which it is
usually necessary to encamp. At all events I should decidedly
take a pillow of this description, for we soon found the voya-
geurs were wiser in this matter than we. In the morning we started
about sunrise, and usually made ten or twelve miles before break-
fast, giving the men a rest of about an hour at breakfast time. At
noon we stopped to lunch, making no fire. Our usual time for en-
camping for the night was seven o'clock, but this depended somewhat
upon our reaching a good camping-ground. Once an hour or so
during the day the men would lie upon their oars, and one of them
would light a short clay pipe, filled with kinni-kinnik* After a

puff or two he would pass it to the next, and when each had had his
turn, it was put away and they took to their oars again.

While detained in our tent by the rain to-day, we employed
ourselves in manufacturing a musquito net out of some muslin we had
brought for the purpose. This being provided with cords, was
stretched at night from one tent-pole to the other, (the tents being
roof-shaped, with flat gables and a tent-pole at each end,) and pegged
down to the ground at the sides, thus forming a tent within the tent ;
an arrangement quite essential to a comfortable night's rest in these

regions.

The point forming the breakwater §of our harbor, and to which
the bateau was moored, presented the first example we had seen
of drift scratches and grooves. Some of the grooves were several
feet in length, the surface a curve of eighteen inches radius, and as
smooth and even as if cut with a gouge. These marks were almost
entirely confined to the inner side of the point, where some of the
scratches could be traced as far below the surface of the water as we

*

could distinctly see, that is, some five or six feet ; the lake side pre-
sented rough points of rock, occasioned, as Prof. A. explained, by the
decomposition of the surface on that side, from its greater exposure
to the wind and waves. In the afternoon, the rain having ceased,
we assembled to hear the Professor's remarks on the specimens of
various rocks collected in the neighborhood.

" Geology," he said, " investigates the great masses of the rocks ; mineral-
ogy the forms and composition of their materials. Geologists are apt to neglect
the study of mineralogy, and thus to overlook the differences, in different
countries, of rocks bearing the same name.

" If geology had been studied first in this country, the text-books of the
science would read very differently. For example, there is no rock in this
region answering the description of true granite. We have granitic rocks
enough, but none of an amorphic structure. All are more or less stratified.
At the beginning of the century, each of the two great schools in geology
maintained that all rocks had but one origin, disagreeing, however, as to
what this origin was. The reason was, each had examined only the rocks
in its neighborhood. About Edinburgh the rocks are trap ; Hutton, there-
fore, referred everything to the action of fire. Near Freiberg there is
nothing but sedimentary rock ; Werner, therefore, would admit no influence
but that of water.

46 LAKE SUPERIOR.

" Most of the rocks in this region are Plutonic, that is, they manifest the
action of fire. The only sedimentary or aqueous rock found here is sand-
stone, the age of which is uncertain, as no fossils have as yet been found in
it.* Probably it belongs to the Potsdam sandstone. It passes frequently
into quartz and quartzose rock. If quartz were broken up, mixed with clay
and lime, and subjected to the action of heat, the forms of metamorphic
rocks would be produced which we see here. Some varieties, however, are
quite peculiar, as, for instance, a red felspar porphyry, with numerous
specks of dark epidot."

The canoe from the Sault arrived this afternoon.

July 3d. — The air was very chilly this morning, when at about
half past five our canoes issued from the little cove into the open
lake. But the prospect before us was sufficient to divert our
thoughts from any discomfort. On our right was the deep bight
of Goulais Bay, terminated by Goulais Point, a high promontory
of the character of Gros Cap. Directly ahead rose the fine head-
land of Mainainse, (" little sturgeon"') distant about thirty miles.
We were yet in the shadow of Gros-Cap, and all the shore in sight
seemed to have the same mountainous character. Ridge over ridge,
distinct at last only by the cutting line against the sky, it had the
freedom and play of outline, which, rather than size, distinguishes a
mountain from a hill. So different was the scene from anything
on the Lower Lakes, that although I knew in general that the shore
of Lake Superior was much bolder and more rocky than that of the
others, yet it took me by surprise, and I was disposed to think this
part of it an exception, until assured, by one who had been here
before, that the grandeur of. the scenery constantly increased to the
northward.

Opposite Mamainse stands White-Fish Point on the south shore,
and the two approach each other somewhat, repeating on a large
scale the feature of Gros-Cap and Point-Iroquois, which is again
repeated on a gigantic scale by Point Keewaiwenaw and the land
of which Otter Head forms the outer extremity. White,-Fish Point
has the outline of a raven's head, with a projecting sand spit for the
bill : the high land above was just visible. We passed this morning
Isle Parisien and the Sandy Islands, low, flat islands covered with

shore of the lake.

trees, like all those in this part of the lake. Several loons flew by
to-daj, and whenever one appeared, the men all began to shout " oory,
oory" which seems to be the Indian " hurrah,"* whereupon the bird
would usually fly in circles round the boat. This was regularly
repeated whenever a loon came in sight ; the experiment was tried
on gulls and sheldrake, but not with the same success.

The sun and wind rose together, so that by eleven o'clock it was
very warm, and at the same time so windy that we were obliged
to make for Maple Island, a low, sandy island, densely covered
with trees. On the lake side the trees were covered with long
lichens, ( Usnea,~) and presented a weather-beaten aspect, much in
contrast with the side towards the land. The shore here was evidently
wearing away, and the roots of many of the trees were exposed.
The beach was covered with large fragments of red porphyry, and
slabs of dark red sandstone, often ripple-marked.

When the bateau arrived we found they had caught some fine
trout on their way hither. This excited the emulation of the other
boats, and hooks, &c.,were forthwith prepared. The tackle consists
of small cod-line, with a hook (or often two,) with a large sinker of
lead melted round it. The bait is a piece of pork, or better, a
trout's stomach, drawn over the hook and tied at the shank. A
simple plate of brass, with a couple of hooks on the lower edge, is
said to be very effective without any other bait, and I have heard
of a pewter spoon being used with success. This is allowed to
trail a dozen fathoms astern of the canoe, and kept in constant
motion by jerking the line. After the first excitement, as the fish
did not bite oftener than half a dozen times a day, and sometimes
not at all, the lines were handed over to the steersmen, who made
them fast round their paddles, and thus kept up the requisite motion
without any trouble. The fish we caught were the lake trout,
(jSalmo ametliystus^) and Siecowet, (Salmo Siscowet Ag., see Plate
I.) ; their average weight five or six pounds. The latter fish is
so exceedingly fat that we found it uneatable. It is said to be
much improved by pickling. White-fish and lake-herring are taken
only in nets, and the other fishes only in the streams. The wind
did not allow us to get off to-day.

48 LAKE SUPERIOR.

July kth. — Thermometer one would guess about 40° Fab. this morn-
ing. Goulais Point is separated from Mamainse by Batcheewauung
Bay, by far the most considerable inlet on the E. and N. E. part of
the lake, (being about ten miles deep, by five across the mouth,)
unless we count as such Michipicotin Harbor, -which is rather the
commencement of a new direction of the shore, than an indentation
in it. The general outlines of the lake are simple, and though cut
into innumerable narrow coves, yet bays of any considerable size
are rare.

Not long after starting we encountered several canoes of Indians,
(gens du Lac,~) on their way to the Manitoulin, to receive their
annual " present" from the British Government. Among them was
a chief, who stood up and addressed our men in his own tongue,
which, as we were informed by Henry, was a separate dialect of the
Ojibwa, but intelligible enough to them. In an unwritten language,
dialects soon spring up. A lifetime, the men said, was sufficient to
make a noticeable change in their language, though where large
numbers are collected together and any kind of schooling exists, the
bibles and catechisms must do much to arrest the process. We
stopped for breakfast at ten o'clock, at a point under Mamainse,
much resembling Maple Island in its general features. Charred logs
and beds of matted leaves on the beach, showed it had been recently
visited.

From Mamainse onward the character of the shore changes. In-
stead of the low sandy islets, we now passed among isolated rocks of
greenstone, rising abruptly from deep water, generally bare, but
sometimes crowned with a tuft of trees at the top. The rock, which
about Gros-Cap is sandstone, often unaltered, now becomes more
highly metamorphic. But the larger islands and the edge under
the cliffs, continue of sandstone, and are flat and low for some dis-
tance to the northward. The line of cliffs is continuous, rising at
a distance of a quarter of a mile at most from the water, with
an average elevation of two to three hundred feet. The whole
surface, down to the very beach, was covered with trees : indeed
I may say once for all, that with the exception of some ancient
terraces of fine sand and gravel to be described hereafter, and a
few summits of bare rock, the entire shore of Lake Superior, as far

NARRATIVE. 49

as we went, is continuously covered with forest. The trees continued
the same, except that the white pines and maples had disappeared.
The number of species is small ; black and white spruce, balsam fir,
canoe birch and aspen, with arbor vitas in the moist places, and here
and there a few larches and red pines, with an occasional yellow
birch ; the spruces prevailing on the high land, and the birch and
aspen near the water, yet everywhere a certain proportion of each.
From the great similarity of the evergreens on the one hand, and the
white-stemmed aspens and birches on the other, at the distance of a
couple of hundred yards the forest seemed to be composed of only
two kinds of trees. The trees are not large, usually not exceeding
thirty or forty feet in height. Yet the whole effect is rich and
picturesque. Here, as in all the features of the lake, the im-
pression is a grand uniformity, never monotonous, but expressive of
its unique character.

The resemblance to the sea-shore often recurred to my mind. Ac-
cording to Dr. Leconte, several insects found here are identical
with species belonging to the sea-shore, and others corresponding or
similar. The beach-pea, Lathyrus maritimits, and Polygonum
maritimum, both of them sea-shore plants, are abundant in this
neighborhood ; the former, indeed, throughout the north shore of the
lake.

Although so cold this morning, yet by noon the heat was intense.
The weather, indeed, during the whole time we were on the lake,
was such as we sometimes have in Massachusetts in September ;
cool morning and night, and warm in the middle of the day. The
sun has great power, and blisters the hands and face unless well
guarded, but the air is cooled by the vast expanse of water,
(which contains ice during the largest part of the year, and even
on the surface is rarely above 40° Fah. at any season,) so that it
was never warm in the shade, or when the sun was below the hori-
zon. We in our canoe being induced to land by a white pebble
beach which at a very short distance had the appearance of sand,
and thus promised an entomological harvest, indemnified ourselves
by a bath in the icy, crystal water. Here was another resemblance
to the sea ; we could dive from the rocks into thirty feet of water,
which, moreover, was of about the ordinary temperature of the

50 LAKE SUPERIOR.

•

ocean at Nahant. Above the beach and parallel to it was a terrace
of sand about fifteen or eighteen feet in height. Others of the same
kind but of various heights we traced during the day, sometimes
only by the terracing of the forest on the different levels.

The cliff, which rose a few hundred yards from the beach, was
cloven to the base, presenting a wide chasm of bare, splintered
rock, several hundred feet deep, nearly parallel to the shore. The
surrounding woods had been burnt, leaving the black stems, some
standing and some lying crossed at various angles, like jack-straws.
The ground was already covered with the fire-weed, (JSpilolwum
angustifolium^) striving to conceal the ruin with its showy blossoms.
Black flies very numerous and troublesome. They appear to have
a fondness for the burnt woods, in which we always found them
abundant.

In the course of the day we passed a deserted mining "location,"
marked by ruinous log-huts ; and in another place we saw on the
rocks the wreck of one of their bateaux. At about five o'clock
we came in together at the Pointe-aux-Mines, or Mica-Bay, as they
call it now. This establishment belongs to the Quebec Mining Com-
pany, who have already commenced operations here. It is a deep
cove, protected on either side by ranges of rocks, with a broad beach
at the bottom, and above this a steep bank, on which, at the height
of thirty or forty feet above the water, stands the very neat wooden
cottage of Capt. Matthews, the superintendent, and about it the
storehouse, the lodgings of the workmen, &c. We were very hos-
pitably received by Capt. and Mrs. Matthews, and enjoyed in their
house the luxury of a civilized tea, before which, however, we visited
the mine, which is about half a mile from the house, by a Brock-
en-like wood-path, nearly all the way up hill.

Capt. M., avoiding the errors of his predecessors on both sides of
the lake, spent eighteen months in making his preparations, securing
a thorough system of drainage, ventilation, &c., before attempting
to get out any ore. The work seemed to be carried on with great
method and thoroughness, and to be in very successful operation.
The present state of the concern he represented as most promising.

July 5th. — The Professor before starting showed us a rock at the
south entrance of the bay, which he considered a proof positive of

NARRATIVE. 51

the correctness of the glacial theory. Its surface was a couple of
hundred yards in extent, sloping regularly north to the water's edge.
The whole was polished and scratched, except where disintegrated.
The scratches had two directions, the prevailing one north 10° to 30°
west, the other north, 55° west. The scratches on the outer or lake
side seemed to have a rather more westerly direction than the rest.
Great numbers of these striae could be traced below the water's edge,
from which they ascended in some places at an angle of 30° with
the surface, showing, as the Professor remarked, that they could not
have been produced by a floating body. The rock is granitic, with
an astonishing number of veins and injections of epidotic felspar,
granite, and trap, often crossing each other so as to form a compli-
cated net-work. Wherever exposed, it was ground down to an even
surface.

The day was calm and very warm. About noon we stopped at
Montreal River, (one of several of this name on the lake.) This
river, forty yards wide at the mouth, empties through a kind of
delta, partly overgrown with large trees. The water is deep and
clear, but of a rich umber color, such as we often see in the small
streams in New England. This is the case with all the rivers we
met with on the lake ; the color was there attributed to the presence
of pitch, an explanation the Prof, thought likely to be correct. At
its entrance into the lake is a broad beach, which on the south forms
a point somewhat jutting across the mouth.

On the northern side, at a short distance from the water, the beach,
which was of small pebbles, had a slope of 30° that is, nearly as
steep as it could stand. We frequently met with such steep beaches,
often of a considerable height. Outside there is a bar which extends
entirely across, six feet below the surface. The stream issues from
the hills through a chasm sixty or eighty feet deep and a few yards
wide, with straight walls of rock, somewhat overhanging on one side.
From this gorge the river issues with great force. Higher up there
was a cascade some forty feet in height, falling from a dark, still
lakelet, and above this again a succession of rapids. This is the
general manner in which the streams on this side of the lake make
their way down from the table-land through the barrier of rock. On
the delta below were several of the largest red pines (P. resinosa,')

52 LAKE SUPERIOR.

I ever saw. I regret that I did not take the girth of one of them,
which must have been five feet in diameter. But the black flies and
musquitoes were so annoying as to absorb much of one's attention ;
the only refuge was the beach, where we had made fires to drive
them off. The heat of the day made a bath very agreeable ; we
found the current of the river at the mouth so strong as to make
some difficulty in swimming even this short distance across.

One of the men killed here a squirrel of the kind that takes the
place of our" Chipmunk" in these regions, the Tamias quadrivittatus.
It resembles our animal, except that it is a little smaller, has a longer
tail, and four black stripes instead of three, on its back. We found
it afterwards much more abundant than any other species, particu-
larly on hill-sides among broken rocks, attracting the attention by its
loud, peculiar cry.

On the bank was the skeleton of an Indian lodge, and a well-worn
trail ran up along the stream. The Indians here as everywhere love
the neighborhood of rivers, where we always found traces of their
camps. As we left the river we saw some of their handiwork on a
rock over the beach. It was the picture of a schooner under sail,
scratched out from the black lichens so as to show the lighter surface
of the rock.

The Professor pointed out here the difference of water action from
that of ice. The former, he said, leaves the harder parts prominent,
although the whole is smoothed, as was the case in this instance, but
the latter grinds all down to a uniform surface, scratching it at the
same time in straight lines.

This afternoon, the water being smooth, we tried an experiment as
to its transparency, by lowering a tin cup at the end of a fishing-line.
It went out of sight at forty-two feet. It is said that Avhen the
water is entirely unruffled and the sky clear, a white object may be
seen at the depth of one hundred and twenty feet.

Passing Montreal Island, a large, low island covered with trees,
some three or four miles from the shore, we threaded our way through
a group of rocky islets and came out into a wide bay, which we trav-
ersed^. e.,took the direct line across, instead of following the curve
of the shore. The voyageurs are in general unwilling to keep out more
than a quarter of a mile or so, and usually coast along the rocks. But

NARRATIVE. 53

this time the weather being so calm, they ventured on a course which
brought us at one time about two miles from the shore. Their cau-
tion seemed to some of us, accustomed to a bolder style of navigation,
somewhat exaggerated. But if the rocky character of the shore,
the suddenness with which both wind and sea rise here, and the
frailness of the vessels be taken into consideration, perhaps it is not
so unnecessary as it would seem at first. Moreover it is to be re-
membered that although a swim of a mile might under ordinary
circumstances be no very desperate undertaking, yet in this icy
water, a person swamped at that distance from the shore would in
all probability be disabled long before reaching it. And even if
the shore were reached, the prospect of having to make one's way
on foot through this rugged, gameless, fly-possessed region to the
nearest trading-post or mining location, would be dismal in the ex-
treme. Deprived of salt pork and biscuit, one's subsistence would
depend on the chance of snaring a hare or two, with tripe de roche
as the sole alternative.

As we pushed out into the bay a weather-beaten veteran in the
Professor's boat struck up a song, the others in the canoe and those
of the " Dancing Feather " joining in the chorus and repeating each
verse as he got -through with it. Their singing had nothing very
artistic about it, being in fact only a kind of modified recital, in
a quavering and rather monotonous voice, coming, with little modula-
tion, from the mouth only, but they kept time well, and it had a
heartiness and spirit that rendered it agreeable. Their songs
were all French ; according to the Professor, the wanton chansons
of the ancien regime, which the ancestors of these men had no
doubt heard sung by gay young officers, in remembrance of distant
beloved Paris. A strange contrast, as he said, between these produc-
tions of the hot-bed civilization of a splendid and luxurious court, and
the wilderness where alone they now survive ! The tunes, I fancy,
are indigenous ; at least, their singing had a certain naivete and some-
times sadness about it quite at variance with the words. Neither
the Canadians of the bateau, nor the Indians (of whom we had one,
with a couple of half breeds in whom the Indian blood decidedly pre-
dominated, in our canoe) joined at all in the singing, either now or

afterwards, though the Indians had a low monotonous chant which
they occasionally grumbled to themselves.

We were looking for a stream called Flea River, where there were
said to be falls of 90 feet, but riot finding it, we decided to encamp
on a sandy beach at the bottom of the bay, where we heard the noise
of rapids. This was the Riviere aux Crapauds, or Toad River. There
seems to be about this continent some pervading obstacle to the giving
of reasonable names to places. In this region, indeed, one is not
troubled with the classicality of New York, for instance, but, as in the
case of those just mentioned, there is nothing very happy in the choice ;
and as for repetition, it is fully as bad as anywhere. There seems to
be no end to Black Rivers and White Rivers and Montreal Rivers,
occasionally varied into Little Black and Large Black, and so on.

As we neared the shore several canoes of Indians came out to
sell fish. Their appearance as they squatted in their canoes, wrapped
in their blankets, brought to mind the pictures of the South Sea
Islanders. Their faces were round, full and rather flat, with no great
projection of the cheek bones, the mouth very wide, with thick ish lips,
and gaping like a negro's. The hair brownish, and not so straight
and coarse as that of the Indians in general. They were very filthy,
and their clothing in general ragged. They seemed, however, good
natured and happy, and grinned widely as they accosted us with
the customary salutation of "Boojou, boojou! " (Bonjour, bonjour).
Their canoes are very small, generally not more than nine to twelve
feet in length, yet each usually contains a whole family ; the man
in the stern, the squaw in the bow, and the intermediate space filled
up with two or three children of various ages, and generally at least
one dog. In exchange for their fish they prefer flour or tobacco to
money, of which they do not know the value very well. Indeed in
any case they seem to regulate their demands rather by what the
buyer offers than according to any notion of relative values. Thus
when we offered in exchange for some fish a quantity of flour
that would have overpaid it at the Sault, they thought it too little.
On the other hand, a fifteen-pound trout was bought for a small
fish-hook. We were afterwards told at Michipicotin (Mishi-picotri)
that an Indian came there once from a distance to buy supplies, and
produced a bundle, in which, after taking off wrapper after wrapper,

Pullins; in for the beach we soon encountered the brown water of

O

the river, but its mouth was not to be seen, the sand-beach extending
apparently unbroken across the cove. When close in, however, we
discovered an opening in the corner, whence issued a rapid current,
and crossing a bar, we entered the mouth of the river, which is thus
shut off b y a spit of sand extending from the south or left bank of the
river, northward across the stream, leaving only a narrow outlet.
Inside, the river has a breadth of forty or fifty yards, flowing through
a wide expanse of sand. This sand-beach is terraced, showing differ-
ent heights of the river, and above the beach a succession of ter-
races was marked in the forest. On the south side the sand spit is cut
away by the current, forming a vertical bank, in which is seen the
horizontal stratification of the sand and gravel. The same general
features were noticed subsequently at other rivers, and seem to de-
pend on a general law.

On landing I walked towards the rapids, about a quarter of a mile
up the stream. The flies and musquitoes made their appearance as
soon as I entered the woods, and jumping down into the bed of the
stream with the intention of sketching the mass of water that was foam-
ing down over the rocks, I was instantly surrounded by such swarms
that there was no getting on without a smudge. Even standing in
the midst of the smoke, so many still clung to me that my paper was
sprinkled with the dead bodies of those killed as I involuntarily brush-
ed my hand across my face. We took refuge on the sand, at a dis-
tance from the woods, and here were comparatively free from them.
But here their place was supplied by sand flies, the brulots or " no-
see-ems," an insect so minute as to be hardly noticeable, but yet more
annoying where they are found than the black flies or musquitoes,
for their minuteness renders musquito nets of no avail, and they
bite all night in warm weather, whereas the black fly disappears at
dark. Such is their eagerness in biting that they tilt their bodies
up vertically and seem to bury their heads in the flesh. We found,
however, that an anointment of camphorated oil was a complete
protection, making a coating too thick for them to penetrate, and
entangling their tiny wings and limbs.

56 LAKE SUPEKIOR.

July Qth. — Weather calm and overcast. Stopped to breakfast at
the mouth of a river much like the last. Hearing the noise of rapids,
some of us made our way up the stream until we came in sight of
the fall, but the musquitoes were so unendurable that we hastened
back.

As the day advanced the wind rose, and gave the bateau an opportu-
nity to use her sails, but only for a short time, speedily coming ahead.
The prospect in front of us was a noble one, lofty headlands rising one
beyond the other until fading away in the distance. The shore, which
had continued to present an uninterrupted ridge three or four hun-
dred feet in height, becomes more abrupt and broken about Cape
Gargantua, with deep chasms from decomposed dikes. The aspect
of the coast here is exceedingly picturesque, steep broken points and
rocky islands and islets generally sloping towards the north, and often
worn smooth, grooved and scratched on the north side. We passed
inside of one cliff, that showed a vertical face of at least two hundred
feet in height, dyed with an infinite variety of colors by the weather
and by the lichens, whose brilliancy was increased by the moist atmos-
phere. One orange-colored lichen in particular, was conspicuous in
large patches. Here and there a tuft of birch aided, by the contrast
of its bright green, the delicate gradation of tints on the gray rock.
On a little strip of beach at the foot of a cliff in a cove called Agate
Bay, we picked up an abundance of very pretty agates and other
interesting minerals. At lunch-time we stopped at a curious rock,
part of which seems as if cut away nearly to the level of the water,
while the rest rises steeply to the height of thirty or forty feet. One of
the common Indian legends about the deluge and the creation of the
earth attaches to this rock, and the Indians still regard it with venera-
tion. According to one of the men, " the Evil Spirit," (N. B. The
gods of the aborigines here as elsewhere are to their Christianized
descendants nothing but the devil, the elder spirit of all mythologies.)
after making the world, changed himself and his two dogs into stone
at this place, and the Indians never pass without " preaching a
sermon " and leaving some tobacco. Even our half-breeds, though
they laughed very freely about it, yet I believe left some tobacco on
the top. This rock is remarkable in a mineralogical point of view.
It is an amygdaloid porphyry containing asbestos and quartz, with

LAKE SUPERIOR. 57

thin layers of chlorite, and injections of granite. Numbers of mar-
tins and barn-swallows {H. viridis and americana) frequent these
cliffs, and often a pair of screaming sparrow-hawks. Farther on, the
hills were burnt over for a great distance, showing rounded summits
of white scorched rock, the lichens and earth mostly washed off from
them, but the blackened tree-stems still upright.

At Cape Choyye, where we encamped, the cliff conies boldly down
upon the lake, the rocks rising from the water to the height of three
hundred feet, with narrow chasms, sometimes vertical, sometimes
slightly inclined, and strewed all the way up with stones, like the
" slides " at the White Mountains. Beyond this it falls away into a
vast basin of green sloping hills, curving inland and then sweeping
out to rocky points beyond. The cliff, wherever the slope allows any
soil to rest, is covered with birches to its base, leaving room for a wide
slope of debris, and a beach that rises in five terraces, the lower one
falling steeply to the water some twenty feet, showing that it alone
can be connected with the present level of the lake, and that the
rest must belong'to former epochs.

At the water's edge were several unconnected masses of dark
red sandstone in place. One mass, which John, our " middleman," *
christened "fire-boat" (i. e. steamboat) we waded out to, in
order to avoid the flies while we bathed. Further on was a broad
sheet of the same rock, sloping gradually from below the water
up to the beach, full of " pot holes," worn into the rock by the action
of the waves on stones lodged in its crevices. One of these stones,
which was nearly round, might have weighed fifty pounds. Some
of the holes were three or four feet deep, and as many in diameter.
One was in the shape of a cloven foot ; others formed steps, the stone
having worn down at one side of the hole for a certain distance,
worked on horizontally awhile, and then downwards again. The outer
part of the rock, over which the water still washed at ordinary times,
was covered with winding channels, of only a few inches' depth, run-
ning off into the lake, formed apparently by the grating back and
forth of sand and small pebbles.

July 1th. — We were off by four this morning, but the wind

was up before us ; and when we started, we foresaw that we
should have head wind to contend with to-day.

At sunrise, the bay north of Cape Choyye presented a noble land-
scape. On all sides but one, an unbroken extent of rounded hills,
so evenly wooded, that as the sun touched the curves at the top, it
looked like a bank of grass. At one spot, far in the bottom of the
bay, a white streak down the hill, and a faint roar at intervals, beto-
kened the cascade of a stream that enters here.

The cove where we breakfasted, narrow and rocky at its mouth,
and expanding inside, had something so liveable and civilized
about it, that one might almost look for a cottage or two on some of
the beautiful points of abrupt birch-clad rock.

On the rocks here, we found the purple flower of the wild onion,
and the pretty Potentilla fruticosa : also brilliant lilies, reminding
one of home. I was quite puzzled at finding our common red
cedar, (Juniperus Virginianus^) which we had not seen hitherto,
creeping on the rocks ; not forming a tuft like the creeping savin,
but a wide-meshed net-work of long straight shoots. *

The shore on the northern side of the bay becomes yet bolder
and higher, attaining, according to Bayneld's chart, the height of
700 feet. Between Cape Choyye and Michipicotin, a distance of
about twenty miles, I did not notice but one beach, and that of
only a few yards' extent. The rocks rise from the water, often ver-
tically, several hundred feet, scored with deep rents and chasms,
from decomposed trap-dykes, and striped down with black lichens.
In some places, huge basalt-like parallelograms of rock stood out like
pulpits. Along the top of the ridge, stretched the never-ending
spruce forest, and wherever a gully or break varied the perpendic-
ular face, a few birches crept downward from crevice to crevice.

On turning the point of Michipicotin harbor, we encountered the
full force of the wind, now fresh from the west ; and what was worse
for us, something of a sea. Our course was such as to bring the
wind abeam, and afford little shelter from the shore. We edged
along from point to point, so close to the rocks that often the oars
almost touched, and we were hardly lifted on the crest of a wave,
before it broke against the cliff, and rushed up into the chasms at
its foot. This was much closer proximity to a lee-shore than one

NARRATIVE. 59

would think prudent under the circumstances, yet our men dipped
confidently on, and never ceased their chatter or their laugh for a
moment, even when the bow man occasionally got a wet jacket from a
wave that broke too soon. In truth, they had such perfect command
of the canoe, that their course was no doubt the safest, for not
only did we thus get some partial shelter from an occasional rock or
point, but also the force of the wind was deadened by the nearness of
the cliff.

At the little beach before spoken of, we stopped to rest. Here
was an abundance of Labrador tea in blossom, Pinguicula, and Poten-
tilla fruticosa. A rapid stream came in at the centre of the beach,
about the mouth of which were multitudes of brook trout ; some were
caught, being the first that we had seen since leaving the Sault,
although they were said to be numerous in all the streams. Beyond
this, we found the rocks along the water much grooved and polished ;
one groove, about six inches deep, I traced for some twenty feet.

A sudden exclamation from the men, as we passed a deep narrow
cleft, called our attention, but too late to see what they maintained
they saw, namely, a quantity of moiv at the bottom of the chasm.
This seemed at first impossible in this burning July weather, with the
thermometer about 80° at noon ; but on reflection, this chasm, open
to the N. W., must doubtless be filled with some hundred feet of
snow in the winter, and the sun can never penetrate into it for a mo-
ment, so that the process of melting in the short summer must be slow.
And then the summer was after all but just set in ; Gov. Simpsow,
if I remember rightly, found the lake full of ice about the first of
June.

We came in sight of the bottom of the bay, a wide and high sand-
beach about a mile in length, but seeing nothing of the river, we
approached a dark object on the beach, ( which we had ascertained
to be an Indian squatting on the sand ) to make inquiries, but he
retreated rapidly, and we had to coast for some distance, before we
discovered the entrance.

Michipicotin River, a rapid stream of clear dark brown water,
some two hundred yards wide, here cuts through the beach at right
angles, leaving a somewhat projecting sand spit on the south. The
name Michipicotin was declared by some of the men to signify " Big

Sandy Bay," certainly quite descriptive of the place, but they were
not unanimous, some of them maintaining that nobody could say what
it meant. It was a pretty hard pull to the factory, half a mile up on
the left bank. Our approach had been already announced, probably
by the Indian whom we saw on the beach, and we found Mr. Swanston,
the gentleman in charge, at the landing when we arrived. He received
us kindly, and showed us where to pitch our tents, in an open sandy
space behind the factory, surrounded by whitewashed cabins, and the
birch-bark lodges of the Indians. A large seine was suspended
from a series of poles, and, near the water, a platform for dressing
and packing fish.

This open space was bounded on the west by a steep ridge of
stratified sand and gravel, some sixty feet high, cut through by the
present channel of the river, and also by an ancient, now deserted
channel further south. The river just above the factory takes a
sharp turn to the north, doubling back in a direction nearly parallel
to its course below. The interval between the factory and the lake,
is thus a peninsula, the base of which is cut across by the former chan-
nel. It is evidently a range of sand-dunes, thrown up by the winds and
waves, so as to divert the stream from a direct passage to the lake,
to a course for some distance nearly parallel with it. From its mouth,
to the Falls, it is a series of abrupt windings, though its general
direction is straight ; indicating, the Professor said, a bay repeatedly
closed by sand-bars, one outside of the other, and successively cut
through by the river. It evinced, he said, a contest between the
river and the lake, beginning at a time when the level of the
water was somewhat higher than at present.

Michipicotin is the principal post of the Hudson's Bay Co. in
this district. From it, the other posts are supplied, and the line of
communication with Hudson's Bay passes through here. It is six-
teen days' journey up Michipicotin and Moose Rivers to James' Bay.

The agent's house is a little one-story cottage, uncarpeted, un-
painted, and if my memory serves me aright, even unplastered, with
panelling and projecting beams of pine, colored only by age ; yet by
no means uncomfortable in its aspect. The casings of darkened
wood, the heavy beams of the ceiling and cornice, the ancient

NARRATIVE. 61

unpainted settle, and the wide niche for the capacious stove, now
stowed away for the summer, had all a cosy and liveable look. And
Mr. Swanston, although he had inhabited this wild country in the
service of the H. B. C., at one or another of their posts, over twenty
years, yet for anything in his manner or appearance (unless it were
that he wore moccasins instead of slippers ) might have left the pave-
ment of Fenchurch Street only yesterday.

The life at these posts is a very quiet, and, doubtless, monotonous
one ; busy during the seasons when the hunters come for their sup-
plies, or to bring in their furs ; at other times, with only the fish
to be seen to when the nets are drawn in the morning, some to
be cleaned and salted, if there is a good haul, and perhaps put into
barrels to be sent to the Sault. An arrival from some other post, a
straggling party of explorers for copper, and above all, an occasional
packet of newspapers from below, — these are the great events. In
such a life, a man changes slowly, but gathers moss in another sense
than that of the proverb.

A few hundred yards above the factory are very pretty falls, on
the Magpie River, * which here empties into the main stream. Two
miles up there was said to be a fine cascade, and a still more re-
markable one fifteen miles up, which could be reached by a short
cut of six miles by land.

Neither the love of the picturesque however, nor the interests of
science, could tempt us into the woods, so terrible were the black flies.
This pest of flies, which all the way hither had confined our ramblings
on shore pretty closely to the rocks and the beach, and had been grow-
ing constantly worse and worse, here reached its climax. Although
detained nearly two days, in order to supply the place of the
Professor's canoe, (too small for his accommodation, and moreover
rotten and unserviceable,) with a larger and fresh one, which had
first to be put in order, — yet we could only sit with folded hands, or
employ ourselves in arranging specimens, and such other occupations
as could be pursued in camp, and under the protection of a

u smudge." One, whom scientific ardor tempted a little way up
the river in a canoe, after water-plants, came back a frightful spec-
tacle, with blood-red rings round his eyes, his face bloody, and covered
with punctures. The next morning his head and neck were swollen
as if from an attack of erysipelas. Mr. S. said he had never seen
the flies so thick. Year before last there were hardly any ; last year
they increased very much, and this season went beyond all his ex-
perience in this region. He consoled us, however, by the information,
that it was nothing to what they have further north. On Macken-
zie's River, the brigades are sometimes stopped by the musquitoes, and
very often are able to advance only by having fires in the canoe.

The little plain on which we were thus collected, presented a stir-
ring scene, with the buildings of the factory, the lodges, the white
tents, the figures crossing from one fire to another, the half-starved
Indian dogs prowling about to pick up anything loose, and the Indian
women and children staring at the unwonted spectacle. The dogs
were small, and fox-like in their appearance, and perhaps take rather
after the foxes, since they bark, (contrary to what is said of Indian
dogs in general,) and like them in a high key. Even the crying of
the children had a wild, animal sound, resembling the barking of the
dogs. A bull and some cows, (N. B. Mr. Swanston sent us fresh
butter and milk, for tea,) and a robin hopping along the ground with
an occasional chirrup, gave it by comparison quite a home look.

The hunters were most of them in the woods making canoes, and
preparing for the winter campaign. In August they come for sup-
plies of ammunition, &c.,and are gone until the weather becomes too
severe to be endured abroad. This is usually in January, but some-
times they do not come in until March.

According to Mr. S. they generally remain attached to the post
of the district where they are born, obtaining their supplies on credit
and paying for them in skins. It is said that they are very
scrupulous about discharging their debts, and although they some-
times have credit for over £100 currency, yet these wild fellows,
whose notions of morality seem in most points so loose, and in the

thrown on the fire will make a good smudge.

midst of the -wilderness, beyond the reach of all compulsion, — rarely
or never neglect to pay every farthing. Their sense of honor
among themselves, too, seems, in some points at least, acute. We
were told that if an Indian finds a beaver-lodge, he cautiously traps
a beaver or two, and then leaves them alone for the season, since
otherwise the animals would forsake the place altogether. This he
does year after year in perfect security that no one will meddle with
them after he has proclaimed his discovery, and it is said that a
beaver-lodge sometimes descends thus from father to son.

July 8th. — Being in Mr. S.'s room this morning, a hunter came
in from the woods to get a supply of tobacco, which, with ammuni-
tion and apparatus for making fire, are the hunter's indispensables,
and are never refused them. His first words (in Indian, for he
understood no English,) were an exclamation at the astonishing
quantity of flies.

Happening to be in want of a tobacco-bag, I made a proposal
through Mr. S. for a rather ornamental one, (of broadcloth of various
colors, with hanging tassels, and worked with beads,) which the
Indian wore at his girdle. He signified his acquiescence, and
handed me the pouch ; but when in return I gave him a five franc
piece, he eyed it curiously, and bursting into a giggle, asked Mr.
S. what he should do with it ? Mr. S. satisfied him on this point
by telling him how much cloth it would buy, whereat he seemed
satisfied, and requested to have the things out of his pouch. These
consisted of a quantity of kinni-kinik, and fire apparatus, being
a small cylinder of wood, hollow at one end, round which was an
edge of steel. A quantity of the fibrous inner bark of the arbor-
vitae being placed in the hollow, is ignited by striking a stone across
the mouth.

So large a number of Indians are collected here, (I think Mr. S.
said about 150,) that it would seem to be a good opportunity for
doing something towards civilizing them. There is certainly room
enough for improvement. They have no church, no schools, no
marriage ceremony, unless it be in the Indian style, every man
having as many squaws as he can support. They do not attempt
any agriculture, but depend on hunting, and when that fails, on the

64 LAKE SUPERIOR.

charity of the traders ; they build no houses but the birch-bark
lodges of their ancestors.

Speaking of agriculture, there is an extensive potato patch attached
to the factory, some of the produce of which we carried with us when
we left. The potatoes, however, are small, and other vegetables are
said not to ripen here, on account of the shortness of the summer.
Yet the winters are not very severe, the quicksilver, Mr. S. said,
never sinking below — 20° Fahrenheit.

The fur trade, he said, was very much on the decline, which
he ascribed to the use of various substitutes for beaver in making
hats. The principal furs at this post are lynx, martin, otter and
beaver. The lynx and the martin are never abundant together. If
the lynxes are plenty, there are few martins, and vice versa. Prob-
ably as their prey is similar, the lynx, being the stronger, drives off
its rival.

Great quantities of fish are seined here ; white-fish, lake-herring,
trout, &c., not only enough for the use of this and other posts, but
also some are sent down to the Sault for sale. The number of white-
fish annually put up on the whole lake, Mr. Swanston estimated at
three thousand barrels, worth on an average $5 a barrel. Of these,
about one thousand barrels are sent away for sale. At Fort Wil-
liam, about five hundred barrels are taken. Out of some fifty thou-
sand specimens that he had seen at Fort William, there were two
with red flesh, like salmon.

July Qth. — This forenoon the canoe was finished ; the sewing of
wattap being renewed throughout, and a fresh coat of gum applied.
This wattap is usually said to be spruce roots, but as well as I could
make out, on this occasion the roots of the ground-hemlock (Taxus
canadensis,*) were used.

We had now got thoroughly used to our men, and they to us.
Our steersman, Henry, whose culinary skill (a prominent qualifica-
tion of a voyageur,) has been already celebrated, was careful and
obliging, but rather slow both in wits and senses in comparison with
John, who, though milieu, was decidedly the genius of the crew.
This man was wholly or mostly of Indian blood, and his real name
an unpronounceable jumble of letters that would take up half a
line. No hawk's eye was ever keener than his ; nothing escaped it ;

nothing was too distant for it to make out. A wiry, sinewy fellow,
of astonishing strength and endurance, and always on the watch for
dangers above and below the water, but his chatter and his merriment

were unceasing ; he laughed more than all the rest, and made all the
jokes beside. Henry spoke English in a very deliberate and rather
inarticulate tone, having probably a diplomatic dread of committing
himself by blunders in grammar. John understood no English nor
French, but he knew instantly what you wanted, and did not often
need even the assistance of pantomime.

They were all thoroughly practised in their craft ; not only as to
the navigation of the canoe, but also in doing and contriving every
thing needful to our comfort. When we landed they waded into the
water to carry us ashore on their backs, (for except where a rock
projected favorably, the canoe could never be brought near enough
to step ashore dry-shod,) then carefully lifted the canoe on to the
beach, and after taking out its contents, turned it bottom up. Next,
a good spot being selected, the tent was pitched, and drift-wood (of
which there is generally an abundance at hand,) collected in
good supply. This occasioned sometimes a good deal of good-natured
rivalry among the various crews, the men of each boat considering
their interests identified with those of their bourgeois, and accord-
ingly making haste to pounce upon the best logs and the softest
camping-ground. This was generally at the top of the beach, to
secure level ground, and moss where there was any. Then they
brought up from the water whatever things they observed we .liked
to have in the tent, to one his gun, to another his insect-net, and car-
pet-bags and bedding for all. In the morning, unless we were up of
our own accord, we were aroused by their " e.mbarquez, embarquez"
and wo to him who lingered many minutes after this warning, for he
was sure to find the tent tumbling about his ears without further
preface, and his loose effects transported to the canoe by these inex-
orable fellows.

For this is remarkable about these men, that obliging and respect-
ful as they are in general, there are certain things for which they
stand out, and will have their way. John, for instance, though the
best fellow in the world, would never allow the due sweep of his oar
to be obstructed even by an inch, and any one whose back or head

came in the way, was reminded of the impropriety by a dig from the
end of it at every stroke, until he withdrew within his proper limits.
About these matters, (which, however, were confined entirely to the
management of the boat, &c., and respected exclusively the public
interests,) they never argued nor attended to arguments, but quietly
persisted in doing as they thought proper.

The immediate shore on our course this afternoon, was lower than
we had had it since leaving Gros-Cap ; rounded, gradual slopes of
rock clown to the water, bare in some places, and the rest covered
with a scanty growth of trees. At some distance back, rounded hills
rose to a greater height.

We were struck here and elsewhere by the regular succession of
coves and points, owing apparently to the trap-dykes, which, instead
of being more easily decomposed than the surrounding rock, and thus
forming chasms, as on the other side of the bay, were here harder,
and so stood out from the rest.*

At several places we observed terraces, and carried two of them,
at various heights, but preserving their relative positions, about two
miles, to the Riv. a la Chienne, where they turned up the valley and
extended along its left bank as far as we could see, having an eleva-
tion of about two hundred feet. Here, according to intention, we
encamped at sunset, fifteen miles from our starting place. This
river is deep, and about ten fathoms wide, umber-colored as usual,
with a broad expansion inside, which, with the , wideness of the
valley and the scanty growth on the terraces (doubtless of sand)
forming its left bank, permitted an extensive view up the stream
into an amphitheatre of high rounded hills, behind which the sun was
setting. There are rapids arid a fall of about ten feet a quarter of
a mile up. We pitched our tents on a spit of sand, broad at the base,
and running out in a point across the mouth of the stream to within
a few yards of the steep rock of the right bank. Just inside the
point, th% bottom sunk sheer down twenty feet. Outside there is
a bar, having only a few feet of water on it.

One of the men collecting firewood on the bank found a bear's

their relative ages, and thus led to the views set forth in the paper on the Outlines of

skull, with two shoulder-blades and some vertebrre, stuck in the
crotch of a tree. The jaws were very neatly bound together with
wattap, and the bones painted with broad stripes of black and ver-
million. Inside of the skull was some tobacco, plugged in with birch
bark. This is said to be a common token of an Indian grave, mark-
ing the dead as a brave hunter. On the bank above were remains
of an Indian lodge.

July 10i7i. — Very cool this morning. The rocks on our course
uniformly sloping south-west to the water, in consequence, the Profes-
sor said, of glacial action. He explained that in order to form satis-
factorv evidence of the action of ice, it was necessary that the slopes
and the- rounding and scratching of the surface should have a direc-
tion different from the stratification of the rock.

We passed this morning several mining " locations," indicated by
poles set up on the rocks. At " Les Ecrits " were rude pictures of
canoes, caribou, horses, snakes, &c., cut out of the black lichens, on
a perpendicular face of rock. We stopped to lunch at a rocky point
forming a shelf nearly level with the water, which was thirty
feet deep alongside. To this the canoes were moored by a moun-
tain-ash sapling at head and stem, the small end tied to the
canoe, and the large end loaded with large stones. One of the men
shot a spruce partridge, (JTetrao canadensis^) the first we had seen,
though they are said to be abundant here.

I climbed up the point, and on the top entered a thic£ growth of
shrubs, Labrador tea, and various species of Vaccinium. The whole
surface of the ground was covered with rich green moss (SpJiagnwii) ,
spreading over the loose rocks a uniform velvet carpet, into which
I several times sunk to my middle. Larches began to appear. The
woods much like those of northern New England, except the prom-
inence of the lichens and mosses here, and the smaller size of the
trees. Contrary to my expectation, and to what had been told me of
the country, the forests are not remarkably dense, and there is rare'ly
any difficulty in penetrating, except in the cedar swamps. The
ground is generally rough, since it is, in fact, the broken slope of the
lake shore. We never penetrated far into the interior, which is said
to be in general thinly wooded. The most striking feature of these
woods is their stillness and loneliness, though as to this the season must

be taken into account. Even in Massachusetts, in July and August,
there are comparatively few birds to be seen or heard, and travel-
lers, among others Prince Max of Neuwied, (who is a naturalist to
boot,) have founded on this fact very false conclusions as to the
scarcity of birds in the United States. The truth is that owing per-
haps to the absence of marked climatic divisions, the birds of this
country extend their migration very far, so that any such comparison
should be made in spring or fall. Then much allowance must be
made "for the change wrought by civilization. Birds and animals
(except the carnivorous ones,) always increase about settlements ;
a well-known fact which our experience confirmed, for about the posts,
and at the Sault, both were always more numerous than elsewhere.
In Chicago, a few years ago, a gentleman told me that the grouse
and quails had increased in that neighborhood eight-fold within his
recollection ; I myself saw numbers of quails in the main street and
on the houses, and was assured that they sometimes entered the shops.
The cause is simply the increase of food. Even deer continue to
increase for some time about settlements.

The shore now became higher and more precipitous, until at Les
Ecourts, marked on Bayfield's chart, " no landing for boats," the
cliffs of sienite rose to the height of eight hundred feet above the
lake. Here were swarms of swallows, and a pair of sparrow-hawks,
the invariable inhabitants of these cliffs. Michipicotin Island was now
plainly visible to the south, distant about ten miles. We had intended
to take it on our way, but decided to put this off until our return.

The sunset was beautiful,' but autumnal ; the clouds in large well-
defined masses, tinged with a suffused roseate hue. Afterwards the
air became cool. It was nine o'clock when we encamped, on a
beach just inside of Otter Head. The bateau, which had detained
us much during the day, remained behind at dark. The " Dancing
Feather," on the other hand, had the start of our two canoes, and
went round the Head.

The beach where we landed 'rose some twenty feet from a narrow
margin on the water, at an angle of twenty to thirty degrees. The
little semi-circular plateau above seemed by the dim light to be sur-
rounded on all sides by a dense forest. ' In stumbling about after
drift-wood, we made the discovery that the upper part of the beach

NARRATIVE. 69

was strewn with lichens, in large tufts or clods, often eight to ten
inches deep by eighteen inches to two feet across ; a few armfuls of
this made a very comfortable bed. After the sunset faded, the
moon shone out brilliantly, and we sat on the edge of the slope talk-
ing of many things, long after our men were snoring comfortably
under the shelter of the canoes below.

July ll£/i. — Daylight showed us that our plateau was a niche cut
in the rock, which rose steeply and with great regularity from all
sides, fringed and covered with trees. We rounded the point of
Otter Head, so called from an upright parallelogram of rock, (hav-
ing, however, so far as I could see, no particular resemblance to the
head of an otter,) resting on the top of the point, and, joining the
" Dancing Feather " at breakfast time, we put ashore and decided
to wait for the bateau. On the way a solitary Indian, excessively
dirty and ragged, came off in his canoe to sell us fish, and turned
out to be the brother-in-law of one of our men, a very decent-look-
ing Canadian Frenchman.

The woods here also carpeted with moss, and sprinkled with Linnoea
and bunch-berry ; here also we found very few flies, and began
to give some credence to the assertion of some of the men, that they
disappear towards the end of this month. Perhaps the change of
temperature may render them sluggish, for we had now crossed the
48th degree of latitude, and the greatest heat of summer, in these
northern regions coinciding more nearly with the solstice, was now
past.

One of my companions and myself making the circuit of a muddy
pond, formed by the damming up of a small stream by the lake beach,
incautiously attempted to return through a patch of burnt arbor
vitses. It is difficult to persuade one's self at a short distance that
these burnt places are so impracticable as they really are, even though
one may have had full experience of them before. You can see
through the trees every where, and the ground is plainly visible
among the stumps. But when fairly engaged, you find the fallen
trunks are piled together in such wild confusion that you seldom touch
the ground at all, but are obliged to get along squirrel fashion (only
not so quickly and easily), by climbing and jumping from one log to
another. Moreover the effect of the fire is not at all uniform ; some

of the wood, without much change of the outside, is converted into
mere punk, so that if you step on it you are precipitated among the
charred logs, and in your passage made feelingly aware that many
of the small branches and ends have been merely sharpened and
hardened by it into spikes. So slow and laborious was our progress
that, having with great difficulty made my way to- the edge of the
pond, I waded along, with the water up to my middle, in several
inches of mud, as far as the fallen trees would allow, rather than take
to the bank. We were about twenty minutes in making less than a
quarter of a mile, and my companion assured me that once on the south
shore of the lake it took him a whole day of hard work to get over
seven miles of this ground.

The shore now became very varied and broken ; not very abrupt, but
rounded hills and points of considerable size coming successively in
sight, and on the water-side numerous picturesque wooded islets of
granite, with abrupt faces towards the south, and polished and round-
ed slopes northward. Wide trap-dykes in the reddish sienite rock
all ground down to an even surface. The wind blew in puffs from
the N. W., alternating with dead calms. The fluctuation of temper-
ature was astonishing. So long as it was calm, the unclouded sun
beat down upon us with all the fervor of our own July, but the mo-
ment the wind sprung up it was October.

Evening coming on, the bateau and the " Dancing Feather" en-
camped, but we in the other two canoes decided to keep on to the Pic
(Peek), which was only ten miles off. Not that we were particularly
anxious to get qn, but having hitherto taken the journey rather leisurely
we thought the men seemed inclined to take advantage of our good
nature. So after tea we started again, the moon shining brightly
and the sunset just fading away.

The Northern Lights, visible to some extent almost nightly, were
unusually beautiful this evening, forming three concentric bows in
the north, the upper one about thirty degrees from the horizon. From
this bow as a base sprang up .long flickering streamers quite to
the zenith, where there was aflecky appearance, as if of light clouds,
which, however, were stationary. Hence radiated tremulous flashes
of light toward every point of the compass.

We reached the Pic about one o'clock, the moon down, and no

NARRATIVE. 71

objects discernible except some Indians and their dogs, and the indis-
tinct forms of their lodges on the beach.

July Vltli. — Before we were stirring this morning, our friends of
the " Dancing Feather" made their appearance, and we learned to
our surprise that they had been encamped for some time and had
already finished their breakfast. The fact was their voyageurs were
a little piqued at our having pushed on ahead of them, and were
resolved we should not gain any advantage by it. So getting up
very early they came up with all speed, and silently passing the spot
where we were encamped, pitched their tent at some distance beyond,
and made haste to get breakfast before we were up.

The Pic is a post of the Hudson's Bay Company ; the smallest
of the three on the lake* ; the name is derived not as we at first
supposed, from the pointed hills across the river, but from an Indian
word, Peek or Neepeelc, signifying, I believe, " dirty water." The
same word occurs in Neepeegon. It is situated near the mouth" of a
rather sluggish stream of turbid, brown water, about two hundred
and fifty yards broad, flowing through a valley, wide near its mouth
and narrowing higher up, apparently a delta of the river. There
are considerable falls at some distance up the river. A sand-bar, on
which there are six feet of water, extends across its mouth, and par-
ticularly on the northern side there is a very broad beach of white
sand, like that of the sea-shore, drifted into hills, and at the top of
the beach into a high ridge or dune, like that at Michipicotin, but
smaller, whence . there is a steep descent into the pitch-pine woods
behind the post. Near the beach is a remarkable dyke of pitchstone.

The establishment consists of a number of whitewashed red-trimmed
buildings of one story, like the fishermen's cottages of our coast, rang-
ed round a hollow square and surrounded by a high palisade. The

is much smaller here than at either of the other posts.

ground inside of this courtyard is covered with plank, and a plank
road, also enclosed by a palisade, leads up the slope from the river
to the gate-way, which is surmounted by a sort of barbican.

July 13^A. — There was a dense mist and an easterly wind this
morning, much like one of our chilly sea-fogs. This was the first in-
stance of fog after sunrise we had met Avith on the lake, though it was
often foggy early in the morning. The air was never colder than the
water, so that condensation could take place only when the saturated
atmosphere was cooled by the lake, unresisted by the action of the
sun, that is, before sunrise. That the air was full of moisture
seemed to be shown by the fact that we could often see our breath
when the air was by no means cold, the atmosphere being so charged
with moisture as to raise the dew point, or degree of temperature at
which the vapor becomes visible, unusually high.

The pitch-pine woods behind the post had been burnt over, and
the trees, though yet standing, were mostly dead, affording food for
myriads of wood-beetles, (Monohamus scutellaris^) whose creaking
resounded on all sides. These in their turn were fed upon by the
Canada jays, and by two rare species of woodpeckers, (P. arctiens,
and P. hirsutus.') The arcticus in particular was very abundant
and noisy, having a shrill, startling cry.

The Professor got a number of fishes, among others a brilliant
green pickerel, a new species. A sturgeon was caught in the river
opposite our tent, in a net belonging to one of the Indians, who dis-
patched him after some contest, with a fish-spear. Prof. Agassiz re-
quested me to make a sketch of this fish, which was some four or five
feet long. This took some time, and meanwhile we observed that all
the inhabitants of the lodge to which it belonged were assembled and
crouching in a row in front of us. We supposed this to be mere curi-
osity, but one of our men happening to come up, discovered that
the whole family had been without food all day, and were waiting
to eat the fish as soon as we were done with it. We were shock-
ed at having committed such a breach of propriety, but the sketch
not being finished, we proposed to them to lunch meanwhile on some
of our pork and biscuit, to which they readily agreed.

July 14£/i. — Started this morning with a strong head wind. We
were obliged to leave behind one of our number, who had been ailing

NARRATIVE. 73

with a feverish attack ever since Mica Bay, and was now pro-
nounced by the medical men too ill to proceed. Fortunately we were
able to leave him in good hands. One of the party volunteered to
stay with him, and Mr. and Mrs. Beggs gave him the best accommo-
dation the post afforded.

This was the only case of sickness during our excursion, although
the mode of life was quite new to most of us, and some degree of hard-
ship was anticipated. But speaking for myself, the only serious in-
convenience was the scorching heat of the sun, which severely blis-
tered the skin wherever exposed.

Our course this forenoon fortunately lay through a labyrinth of
islands, by which we avoided the force of the wind somewhat. Just
after leaving the Pic we passed through a river-like channel, about
fifteen feet wide, the steep sides of which were deeply scored in a di-
rection diagonal to the chasm, showing, the Prof, said, that the body
by which the marks were made, had a momentum sufficient to disre-
gard the shape of the ground over which it passed. The striae here-
abouts were inclined at an angle of 39° with the surface of the
water.

We stopped for lunch on a point covered with Vaccinium uligino-
sum, and similar shrubs. The slimy water-plants floating along this
point were filled with astonishing numbers of drowned insects, and
many fine specimens were obtained. From here it was neces-
sary to make a traverse of some three or four miles with quite as
much wind as we could stand up to. This brought us into a cluster
of islets abreast of Pic Island, a fine bold peak seven or eight hun-
dred feet high, stretching off into a rocky ridge. The whole skeleton
and structure of the peak were distinctly visible, from the effects of
a fire that had streamed up the side of the mountain from a cove
on the north, where there is a camping-ground. The Indians and
voyageurs in their carelessness and wantonness allow their camp-fires
to extend into the woods, which on these rocky slopes are dry and
inflammable. The consequence is that the foliage of the trees being
destroyed and their roots killed, they no longer hold together the soil,
and it is accordingly swept off by the next rains, leaving a clean sur-
face of white, calcined rock for Nature to cover again in the course
of ages, by the slow succession of lichens, shrubs and trees.

74 LAKE SUPERIOR.

While passing this island, two canoes came in sight from the op-
posite direction, evidently making a wide traverse for the Pic. They
passed rapidly along under sail too far off to be spoken, but we had
no doubt that it was Gov. Simpson of the Hudson's Bay Company,
who was expected at the Pic on his annual tour. We afterwards
learned that this conjecture was correct, and that he arrived about
eight o'clock that evening, thus making in three hours (for it was
about five when we passed them,) what we had taken all day for.

The Governor is much noted for his rapid travelling. On one
occasion he is said to have dined one day at the Sault, and break-
fasted the next at Michipicotin, a distance of one hundred and twenty
miles. We encamped this evening on a most picturesque rocky islet
near the shore, where we slept on natural beds of solid moss and
huckleberry bushes, a foot deep.

July 15£/i. — Rain early this morning, but cleared away cold, with
an autumnal sky and high wind. We passed the Slate Islands, high
and blue, at the distance of seven or eight miles, and ran into a
cove, at the bottom of which opened what seemed to be a well-ordered
lawn, with balsam firs and larches judiciously disposed at intervals.
In landing, the rich green grass turned out to be bear-berry, and
the soil mere sand, which the bear-berry loves, but which accounted
for the scantiness of trees.

The woods were crossed and recrossed in every direction by rabbit
(or rather hare) paths, and we saw some trails that some of us fan-
cied might be caribous', with many tracks of a dog or wolf. Caribous
are found all through this region, but not in great abundance. An
Indian who passed last winter on Isle St. Ignace, killed twenty-five
caribous in the course of the winter, and was thought to have done
very well. We saw here, for the first time, Parus hudsonicus, in
company with a number of its cousins, the chickadees, from which it
was to be distinguished only by its brown head, its slenderer and
higher note, and a slight difference in habit, fluttering more about the
ends of the twigs.

We made a long stay here, and some of the men amused themselves
with lighting a fire, which unfortunately ran along the ridge of the
beach, and, in spite of their utmost exertions, marched with a broad
front into the woods. It was an exciting spectacle, the eagerness of

NARRATIVE. 75

the flames to seize upon each fresh tree, winding round it like ser-
pents, crackling and rushing furiously through its branches to the
top, until every fragment of dry bark, lichen, &c., was consumed.
The fire seems too dainty to take the more solid parts, and so, for
instance, the bunch of upright cones at the top of the balsams, re-
mains distinguishable in the forest as a blackened tuft. Our beautiful
bear-berry lawn looked now more like a peat-bog. When we left,
the fire was in full progress, and was probably stayed only by a
swamp beyond.

Nature, however, generally provides that no land that can be of
much value to man shall be subject to this fate, for the heavily-tim-
bered (and thus fertile) land of these latitudes is mostly too wet to
burn, except the solitary birches, which if you set a torch to them,
go off like rockets, but do not set fire to the other trees.

We passed terraces several times to-day, and in one place in par-
ticular, on a grand scale at the bottom of a bay, forming a series of
vast unbroken arcs of about a mile chord, ascending one above the
other to the height of several hundred feet, and, from the scantiness
of the vegetation, evidently composed of sand.

Camped on a beach of coarse, dark sand, under a high abrupt prom-
ontory, enclosing it with precipitous walls. Among the rocks in our
neighborhood were discovered veins of copper, suggesting to the Pro-
fessor some remarks, which he illustrated on his black canvas,
pinned against the side of his tent :

" Veins are formed sometimes by the cracking of igneous rocks as they
cool ; sometimes also by the subsidence of strata; cracks being formed, are
filled from the melted mass below, pressed upon by sinking strata and
thus forced upwards, or thrown up by other causes. The injected mass,
even though originally the same as that into which it penetrates, may yet pro-
duce a vein of a different character, from the difference of cooling. Where
the injected mass is very great it alters the surrounding rock, more or less
in proportion to its vicinity to the melted substance. In these meiamorpliic
rocks, as they are called, such as we have seen in great abundance
throughout our passage along the lake shore, there is accordingly the
greatest variety of character, and one species of rock passes into another by
so many intermediate forms that it is often difficult to say what name should
be given to it, the rock, originally sandstone, perhaps, with various admix-

76 LAKE SUPERIOR.

tures, being changed into sienite or porphyry, or into rock partaking in
various degrees of the characters of both, by the influence of large veins of
melted materials. Metallic veins are sometimes formed in the same way,
by injection, and they also in the same manner modify the surrounding rock,
as in the instance before us. Sometimes, also, they are formed by sublima-
tion into crevices, or by electro-magnetic action, causing an interchange of
particles between various parts of the rock."

July 16^/i. — Early this forenoon the Island of St. Ignace ap-
peared looming up in the distance. We passed the " Petits
Ecrits," a rock ornamented with representations of various ani-
mals, canoes full of men, &c., together with various fabulous mon-
sters, such as snakes with wings, and the like, cut out of the
lichens ; the work of the Indians, or perhaps of stray miners or search-
ers for copper, who, as appeared by dates and initials, have adopted
from them this mode of attracting the -attention of the passer-by.
These pictures were of various dates, as was shown by the various de-
grees of distinctness, as the rock was either quite laid bare, or the black
lichens had more or less completely recovered possession of it. We
now entered the vast archipelago of islands occupying the whole
N. W. corner of the lake, as far as Pigeon River, a distance of about
two and a half degrees of longitude, viz. : from 87° 30 ' to 90° "W.
It is difficult to convey any notion of the vast number of islets and
rocks in this part of the lake. Capt. Bay field in his (unpublished)
chart of Lake Huron, is said to have laid down thirty-six thousand
islands, on twenty thousand of which he has landed ; the number in
Lake Superior cannot, I should suppose, fall much short of this. In
both lakes the islands lie almost exclusively along the northern and
eastern shores. In Lake Superior, with the exception of the group
called the Apostle's Islands, there are very few islands on the south
shore, or on the north-west shore beyond Pigeon River. In Lake
Huron there is scarcely an island outside the Georgian Bay, and in
the lower lakes islands are almost entirely wanting.

As we were passing under an overhanging cliff where nests of the
barn-swallow were niched into the rock within reach of the hand,
an Indian in his canoe with his squaw and child suddenly glided
alongside from some cove, and offered fish in exchange for tobacco.

NARRATIVE. 77

He was a huge fellow, with a great head, covered with dishevelled hair,
yet not ill-shapen, and having something of the picturesqueness of a
bowlder of granite. The woman had on a sort of cloak of white hare-
skins, with a hood attached, which was drawn up over her head. Some-
body gave the man a cigar, and showed him which end to put into his
mouth and how to light it, which he did, and smoked away very clev-
erly. Signs were made to him to give the woman a puff, but she un-
luckily put the lighted end into her mouth, and after that good-
naturedly but firmly declined to have anything to do with these new-
fangled pipes.

The wind meantime had risen, and coming out from the lee of the
islands into an open bay, we found the head wind and sea too strong
to be contended with, and so put back into a cove, the entrance of
which we had just passed. Passing through a narrow strait we came
into a quiet bay that seemed like a land-locked lagoon, but was in
fact separated from the lake only by a couple of islands. The sides
of the cove rose steeply from the water's edge with only a narrow
circlet of sand between the water and the trees, in some places hardly
leaving room to pass outside. Thus protected, the little bay, with its
fringe of birches and arbor-vitses, as unruffled as some inland pool of
a still September afternoon, presented a strong contrast with the
turbulence of the weather without. I climbed up the steep bank,
which was everywhere covered with deep beds of moss, and penetra-
ted with some difficulty to the outside of the island, for an island it
was, and the reader must understand that at the " Petits Ecrits" we
quitted the shore, which here trends to the northward, and pursued
a westerly course among the almost continuous islands, intending to
pass outside of St. Ignace.

The spruce woods here were very dense, and encumbered with
fallen birch trunks, as if the spruces had usurped the place of a
birch forest. Part way a sort of path was broken, and fresh tracks
of some large animal, sinking a foot deep into the moss; — prob-
ably a lynx, as they abound here. Hare tracks in all directions.
Snares were set in the evening, and two hares caught. The method
of setting these snares, which is extensively practised by the Indians,
is this. A well-frequented hare-path being selected, is blocked up
by a fence of sticks, leaving only a narrow passage over which a

78 LAKE SUPERIOR.

running-noose is stretched ; the animal in jumping through gets caught
by the neck. It is said that they can hardly be made to leave the
path, and they are thus very easily caught. The Indians rely much
upon them for support, particularly in winter.

On the outside of the island were rough beaches of large stones,
and rocky points against which the waves were beating furiously.

This evening as we were arranging the musquito-bar in our tent
(a nice job and one requiring abundance of light) , our candle proved
to be missing, and we supplied its place by piling on the fire a large
quantity of usnea, which streamed from all the trees. This is
not an unimportant article in the economy of these regions. There is
no better material for the packing of specimens ; it makes capital bed-
ding, and it is so inflammable that a tree covered with it makes the
best possible beacon or signal-torch. The Indian women use this as
well as moss for stuffing the bottom of their portable cradles.

The wind fell in the course of the night, and there was rain before
morning.

•July llth. — Cloudy and warm. Made a traverse at sunrise of
three or four miles, and then began again to thread our way through
endless woody islands of greenstone, often showing vertical sides.
The main shore was now several miles distant and constantly reced-
ing in high domed summits. St. Ignace, high in front, black to the
top with spruce forests ; and a dim, majestic outline in the far distance,
seeming only to divide one part of the sky from the other, our voya-
geurs declared to be Thunder Cape, seventy or eighty miles off. The
ends of all distant points were turned up by the effects of the mirage,
a very common phenomenon here, owing to the contrast in tempera-
tures between the air and the water.

We ran into a narrow bay on the east end of St. Ignace, the bot-
tom of which approached a peak marked on Bayfield's chart as thir-
teen hundred feet above the lake. This bay is a quiet little nook,
hedged around with larches and other trees, over whose tops appeared
the peak. A small clearing had been made here, it being a mining
" location," and on a board fixed to one of the trees was an inscrip-
tion signifying that the spot had been " taken possession of by the
Montreal Mining Company, June 5, 1846." They had even gone
so far as to put up a log-house, yet standing in tolerable repair,

NARRATIVE. 79

with a crib for sleeping inside, and " Douglass' Hotel" written on
a board by the door. This was one of the many places (there are
several on this island), where works were commenced without any
proper exploration of the ground, the only indication of ore being
some veins of calc-spar, which by a too hasty induction was sup-
posed to be a sure sign of copper. Smah1 quantities of native copper
were found, but not sufficient to pay for the trouble of getting it.

After breakfast, the weather being favorable it was decided to make
the ascent, and we started accordingly, taking a narrow gorge that
one of the men, who acted as guide, said led to the peak ; but stop-
ping behind for a moment, I lost the party, and could not distinguish
the trail amid the multitude of hare-tracks through the woods. I
shouted, and was answered repeatedly, but the voices were so echoed
back and forth in the narrow valley, that I could not make out their
direction, and went back to the camp.

In the afternoon they returned, reporting a very fatiguing climb,
the barometer broken, and the flies very troublesome. The black fly
is fond of high and dry situations, and is always found in greater num-
bers about the top of a hill than at the foot. They had ascended the
peak, however, and christened it Mount Cambridge, in case it had
not already been named. The summit was steep and rocky, the
rocks polished and scratched to the top. Contrary to expectation
they found no change whatever in the vegetation.

The woods here were filled with Linnaea, and several species of
Pyrola. We left at five o'clock, passing outside of the island.

St. Ignace seems to be a collection of peaks, and in the middle a
long interrupted ridge, that seemed still higher than Mt. Cambridge.
We encamped this evening on a long narrow island lying north and
south, consisting of two beaches meeting in a ridge in the middle,
and composed of large angular fragments of porphyry with only the
corners worn off. Each side of the island was ploughed from one
end to the other with furrows a foot or more in depth, parallel to the
water. The stones were covered with great clods of lichen, and a
few mountain-ashes and spruces grew along the dividing ridge.

July 18th. — Started at sunrise with our India-rubber cloth for a
sail, the wind being for once favorable. In rounding the end of
the island AVC found furrows like those above described, but at right

angles with them, running across the end of the island. Our course
lay through long river-like channels, formed by parallel series of rocks
and islets. Near evening we passed a number of Indian lodges clus-
tered on an island, with the usual number of barking dogs and squalid
children, and hoped to get fish from them, but they had none except
dried, which is tough and tasteless, in texture and appearance some-
what resembling parchment.

In the night it blew hard from the westward, and we waked up in
some anxiety lest our tent should be capsized, but John was already
on hand and secured it.

July 19^A. — Detained here by the violence of the wind (degrade,
the voyageurs call it,) until about three P.M., when we pushed on
past Point Porphyry, and encamped in a deep narrow bay to the
northward, stopping on the way to examine an interesting locality
where altered red sandstone and trap were seen in close contact.

In the sandstone were ripple-marks and cracks, such as one sees
in a dry mud-flat. The surface in many places had an oily smooth-
ness, and in looking down upon it one might easily have taken it for
a bed of red mud just left dry.

This cove was evidently a favorite camping-ground, from the marks
of recent fires, and the large number of lodge-poles on the bank.
Near the water's edge was a quantity of spruce bark, saddled in
sheets one over the other on a horizontal stick, like the roof of a
house. We at first took it for a grave, but it afterwards appeared
that it was only the bark-covering for the lodges, thus disposed in
order to keep it sound. It rained hard in the night, with thunder
for the first time on the lake.

July 20£/i. — Calm and cloudy. At a distance to the northward
were two twin hills, called " les mammelons" by the voyageurs, and
by the Indians, much more aptly, " the Knees." One could easily
fancy the rest of the gigantic body lying at ease on the plateau, with
the head to the north, and the knees drawn up in quiet contempla-
tion of the sky ; perhaps Nanaboujou, or the First Man.

We soon came in full sight of Thunder Cape, a magnificent ridge,
1,350 feet high, according to Bayfield, running out into the lake
directly across our path. It is composed of metamorphosed sand-
stone, the horizontal stratification plainly visible, from a distance, on

the face of the vertical wall of basalt-like columns rising out of the
forest that clings about its base and sides. Near at hand, the hori-
zontal lines disappear, being in fact rather suggested than clearly
made out, and only the vertical chasms are seen. As we passed the
end of the cape we found the ridge narrow and precipitous on both
sides, forming a wall across the mouth of Thunder Bay. Another
fragment of this wall we had in the southern ridge of Pie Island,
on our left. It is continued by the high, narrow islands beyond,
and repeated in the parallel ridges of Isle Royale.

We stopped to lunch at Hare Island, a little bit of gravel with
few stunted spruces, but covered with grass and an abundance of
flowers. We now had before us a traverse of about fourteen miles
to Fort William, the white buildings of which were visible amid the
dark swamp across the bay.

The wind was rising, but we set off, and the boats were soon far
apart. Our canoe and the Professor's made for the southernmost
entrance of the river on which the post stands, as the nearest, and
were glad to escape into quiet water from the rough waves of the bay,
several of which found their way into our boat in spite of all Henry's
care and skill. The entrance of the river is wide and shallow, en-
closing a large delta, cut through the middle by the stream, so that
the river has in fact three mouths, the northern and southern ones
some two or three miles apart. Some distance outside the mouth
the water became very shoal, and islands were forming, on which a
few willows had already taken root.

The river-water is of the usual dark brown, and tolerably clear.
The banks swampy, densely wooded, and lined with water-plants,
among others the elegant heads of the sagittaria, also nuphar, equi-
seturu, bull-rushes, &c. Such was the luxuriance of the vegetation,
that it reminded one of a swamp in the tropics, rather than of a
northern river.

The name of Fort, applied to this post of the Hudson's Bay Com-
pany, dates from the old days of the Northwest Company, (to whom
it formerly belonged,) and their quarrels with the Hudson's Bay.
At that time the place was strong enough to induce Lord Selkirk,
who came up with hostile intent, to take the trouble to bring with
him a field-piece, which he planted on the opposite bank of the river,

to make them open their doors. In those days a grand annual coun-
cil of the company was held here, and we hear traditions of banquets,
and crowds of clerks, and armies of hangers-on of all kinds. But all
this has now disappeared. The trade has fallen off, the gross re-
ceipts being now, they say, only about <£600 per annum ; and more-
over the Northwest is merged in its old rival, and all those troubles at
an end, so that although the court-yard is surrounded with a palisade,
and there is a barbican gate- way, as at the Pic, yet these fortifications
are not very formidable at present ; the old blockhouse behind is
falling to pieces, and the banqueting hall has probably been burnt up
for firewood, at least, we saw nothing there that looked like it.
Even the little flower-garden opening out of the stone-paved court-
yard was overgrown with weeds.

The general arrangement here is much the same as at the other
•posts, only the soil (a yellowish sandy loam) being better, and the
climate less severe, the cultivated ground is more extensive, and
they have a herd of some thirty cows. Sheep also are kept here,
and several of the dogs were in disgrace, with heavy clogs fastened
to their necks, for sheep-stealing. As the pasturage on the other
side of the river is much better than about the Fort, these cows swim
across regularly every morning and back in the evening, a distance
of two or three hundred yards. I was much surprised, the morning
after our arrival, when the cattle were let out of the yard, to see a
cow walk down and deliberately take to the water, of her own accord,
the whole drove following her, swimming with only their noses, horns
and tails showing above water. An evolution so out of the usual
habits of the animal, that I could account for it only by supposing it
to be an ancient custom, established with difficulty at first, on the
strong compulsion of necessity, and subsequently yielded to from
force of example by each cow that successively entered the herd.

The land about the post is low and flat, mostly a larch swamp ;
a wide gap being broken in the rocky rim of the lake by the
valley of the Kaministiquia. To the northward the hills retreat to
the distance of eight or ten miles. Southerly the line is resumed by
McKay's Mountain, a ridge of greenstone gradually ascending to-
wards the north-west, to the height of one thousand feet, and there
broken into an abrupt precipice.

NARRATIVE. 88

The post is still an important one, as being the portal to the Red
River country, Lake Winnipeg, and the north-west, and furnishes
various supplies to other posts, among other things, of canoes, of
which some seventy or eighty were lying here in store. It stands
on the left bank of the northern mouth of the river Kaministiquia,
about half a mile from the lake. Outside, close to the water, are the
log-cabins of the Canadians attached to the post, and on the plain
across the river the birch-bark lodges of the Indian hunters.

Mr. Mackenzie, the gentleman in charge, received us very kindly,
and handed to us a number of letters and newspapers that had been
forwarded hither from the Sault, by the propeller, which had come
up the south shore and touched at Prince's Location, about twenty
miles west of this.

July 21s£. — Spent the day here. Wild pigeons, cross-bills, and
ravens about the fort, and partridges in the swamp. Bathed in the
river ; the bottom muddy, and the water warm. Mr. M. says that
before a gale from the northward the river falls sometimes eighteen
inches in twenty-four hours. This they supposed to be owing to a
heaping up of the water on the southern shore (where these gales
usually commence,) by the wind, causing a corresponding depression
on this side. The fact, more accurately described perhaps as a
difference of atmospheric pressure on the two sides of the lake, was
afterwards confirmed by several persons. We decided to ascend the
river as far as the Kakabeka (Kah-kuhbeka) Falls, twenty-five miles,
to-morrow. Mr. Mackenzie kindly offered to go with us, and fur-
nished us with whatever was necessary for the excursion.

This evening our men, with some of the employes of the post, had
a dance in a cabin near the Fort. The music consisted of a squeak-
ing fiddle, and none of the fair sex honored the assemblage with
their presence, yet they stamped away half the night with the
greatest' jollity.

July 22c?. — We started this morning accordingly, in three canoes,
Mr. M. following after in a little cockleshell about a dozen feet long.
The men in the two large canoes were placed two on a seat and furnish-
ed with paddles instead of oars, and there was a good deal of rivalry
between them for the first few miles, the paddles dipping with won-
derful rapidity, so that they looked like a row of tailors sewing

84 LAKE SUPERIOR.

against time. I did not time their stroke, but the rate must have
been upwards of sixty dips per minute, for their common oar-stroke
was forty-five per minute, and this seemed twice as quick.

A mile or two up, the river is narrow and the forest closes again
upon its banks, which are somewhat higher ; the trees larger than
any we had seen on the lake ; at first mostly aspens, afterwards
spruce and elm. Five or six miles up, the banks are often thirty or
forty feet high, and in some places broken away, showing horizontal
layers of yellow, sandy loam, occasionally interrupted by sand and
by narrow beds of clay. The margin of the river filled with sagittaria
and other water-plants. Mr. M. says ducks and geese are very
abundant here in spring and fall. At present there were only a few
creek-sheldrakes.

The course of the river is very winding, and our men cut off half
a mile or more in one place, by making a portage through the woods
from one bend to another. They carried a surprising weight of lug-
gage, suspended on the back by a portage strap, a broad thong of
leather passed across the forehead.

For the distance of eleven miles the current is very sluggish.
Then we came to rapids, where it was thought advisable to get out
and make our way by land, leaving the men to pole the canoes up.
We disembarked on a piece of marshy bottom-land, covered with a
fine growth of elms. After proceeding some distance through rank
grass and undergrowth, we came to the bluff, which was a very stiff
fifteen minutes' climb. This brought us on to a table-land covered
principally with scrub-pine (P. Banksiana^) much like our com-
mon pitch-pine, but more pyramidal in shape, with shorter leaves and
curious contorted cones. This table-land was dry, sandy, and thinly
covered with wood, with wide openings covered only by scanty, with-
ered grass. The fire had been through in several places, and
here woodpeckers and black flies abounded. This seems, from what
we heard, to be the general character of the interior, except on the
water-courses.

A fast walk of two hours and a half brought us to the river,
where we waited about an hour before the boats made their appear-
ance. All of them had touched repeatedly, and received some
scratches ; one had been obliged to put in to gum up a leak. We

NARRATIVE. 85

reembarked, but the current was still rapid ; in some places we
estimated it at six miles per hour. At the De charge des Paresseux
we again landed, and walked up some hundred yards while the men
pushed the boats up with poles, which they grasped by the middle,
using the ends alternately on each side.

We encamped at sunset, climbing up a steep clay bluff to an open
spot above, for we could find no landing on a level with the water.
Very cold in the evening, silencing the swarms of musquitoes that
greeted us on our first arrival.

July 23 d. — Very cold this morning also, and the dew heavy.
Even inside of the tent some of the blades of grass were hung with
dew-drops, and outside every thing was as wet as if from a smart
shower. Without breakfasting we walked through the dripping
woods to the Falls. On the way I noticed an old martin-trap, made
like the culJieag of our woods, viz. the butt of a sapling arranged to
fall like a portcullis across the mouth of a hole in which the bait is
placed. We came out first in an open space, bounded by a broken
cliff of slate-rock, whence we could hear, but not see the cataract.
The river here flows between high perpendicular walls of rock, and
here commences the Portage de la Montague. Following up the
portage path about a quarter of a mile, we struck off through the thick
arbor-vitse woods, guided by the roar of the fall, until we came out
on an open grassy bank in front of it, and so near that we were drench-
ed by the spray.

From where we stood we could look up a long reach of the
river, down which the stream conies foaming over a shallow bed,
thrown up in jets of spray, like the rapids at Niagara. At the brink
the stream is compressed, and tumbles over in two horseshoe-shaped
falls, divided in the middle by a perpendicular chimney-like mass of
rock some feet square, the upper part of which has been partly turn-
ed round on its base. The entire height of the fall is about one
hundred and thirty feet, but somewhat filled up by fragments from
above. Its breadth is about a hundred and fifty yards.

The rock is clay-slate, the strata dipping two or three degrees south-
ward, that is, from the fall. Just above the pitch, the slate is broken
into very regular steps, and the same structure is visible in the face
of the cascade itself, particularly on the right, from the broken water

where they project. On the other side, where the descending sheet
is less broken, the rich umber color of the stream tinges the foam
half-way down.

The name Kakabeka was explained by some of the men to mean
" straight down :" i. e.., falls par excellence, it being the most consid-
erable waterfall in this region.

In the afternoon our friends of the " Dancing Feather," who had
determined to return to the Sault by way of the south shore, made
haste to depart, as we had appointed the 15th of August to meet at
the Sault, and they had much the longer way to go. Mr. Macken-
zie left us at the same time.

The Professor this afternoon invited some of us to make the at-
tempt with him to push up the stream as far as a small island at the
foot of the Falls, in order to see them from below. For a short dis-
tance we got along very well, taking advantage of a counter-current
near the opposite bank. Soon, however, this assistance failed us,
and we were exposed to the full strength of the stream. For a
moment or so with all the men could do we could only hold our
own, and then began to go astern, but Jean Ba'tiste caught the
branch of a tree and checked the boat, and then jumping into the water
actually dragged her along, the rest straining their utmost with the
setting poles. The stream here was shallow, and hurried along with
great force, eddying and spouting into the air over the stones with
which the bottom is covered. For a moment or two it was a fair
struggle between muscle and the force of gravitation ; then we got
under the lee of the island, and without farther difficulty landed on
the lower end. The island consists merely of a heap of large angu-
lar stones, with a tuft of bushes in the middle.

At the upper end we sat down on the rocks, with the falling hill of
water directly in front of us, its outline against the sky. Our posi-
tion was a favorable one for feeling the full force of the mass of
water, but did not command the whole of the fall, each side being
partially hidden by the projecting cliff. Indeed there is no position
from which the whole can be taken in at once.

The distinguishing feature of these falls is variety. In the first
place each of the two side-falls has worn out for itself a deep semi-
circular chasm, which, with the foot of the cliff projecting from below,

NARRATIVE. 87

gives the appearance of two horseshoes joining in the middle, as if
two separate streams had happened to come together here. This
peculiar conformation throws the masses of water together in the
middle, whence they are thrown up again by the resulting force, as if
shot out of a cannon. The turmoil is farther increased by projecting
rocks, (perhaps piles of fragments from above,) which, on the right
particularly, shoot the water inwards towards the centre, at right
angles with the course of the river. Then the sharp projecting shelves
which project, especially on the right side, through the falling sheet,
cause a succession of little falls in the face of the great one.

All these peculiarities are due no doubt to the nature1 of the rock,
which, dipping slightly from the fall, and not being underlain by softer
strata, as at Niagara, its recession is not regular, but depends on the
accidental dislodgment of blocks on the edge, by frost, collision of
ice, &c., and the blocks again, when fallen are not so readily decom-
posed or removed. Hence, also, the shallowness of the channel below.
Some of our friends who meanwhile had been exploring above the
Falls, reported a small fall, ten or fifteen feet in height, about half
a mile above, where the slate was replaced by sienite.

We had some thought of proceeding up the river to Dog Lake,
two days' journey to the north. But our men grumbled very much
at the thought of the portages, (one of which from its destructive-
ness to shoes is called Knife, or Devil Portage ;) then our canoes
were too large for the undertaking, and might possibly be knocked
to pieces ; so we concluded to give that up.

July 24£/j. — Last night was warm and rainy, and we started down
the river this morning in a drizzle. We stopped at the clay-bank,
above which we had encamped before, to get some clay-stones,
which occur here hi abundance at the water's edge. These are
nodules of clay, some soft, others of the hardness of chalk or harder,
often in shapes requiring little aid of the knife to transform them into
fantastic images. Capt. Bayfield says the bottom of Lake Superior is
of clay, which readily indurates on exposure to the air.*

Kaministiquia, according to our native authorities, signifies " the
river that goes far about," which this river certainly does, though in

the course of its windings it presents such a variety of beautiful
scenes of overshadowing forest, that we did not grudge the delay.
Two or three miles down, long after we had lost the roar of the Falls,
it suddenly came to us again, quite distinctly and unmistakably,
probably owing to some shift of wind.

This valley is the only spot we saw on the lake that seemed at
all to invite cultivation ; indeed, if we except the posts, almost the
only place where cultivation seemed possible. The better quality
of the soil was abundantly manifest in the size of the forest trees.
The crumbling banks of loam and sand furnished abodes to large
numbers of sand-martins and kingfishers. We were seven hours
in reaching the Fort, and found our companions had left two hours
before.

CHAPTER III.

FORT WILLIAM BACK TO THE SAULT.

July %5th. — We proposed to visit the copper-mine at Prince's
Location, on the shore of the lake about twenty miles to the west-
ward, and thence to cross to Isle Roy ale. In order to travel more
rapidly we sent the bateau back to Point Porphyry to await our
return, and proceeded with the two canoes only.

Starting at about ten o'clock, we found the wind strong ahead
and encamped early in a bay about fourteen miles from the Fort.
On the way we passed Pie Island, a large mountainous island,
so called from an isolated peak on the west, which bears a strong
resemblance, not at all to a pie, but to a French pate, or pasty, with
high sides ; and this is its true name. A porcupine was killed on
the beach as we landed, and proved very good meat.

In the evening the Professor made the following remarks on the
distribution of animals and plants :

" There is no animal, and no plant, which in its natural state is found in
every part of the world, but each has assigned to it a situation correspond-
ing with its organization and character. The cod, the trout, and the stur-
geon are found only in the north, and have no antarctic representatives. The
cactus is found only in America, and almost exclusively in the tropical
parts. Humboldt, to whom the earliest investigations on this subject are
clue, extends the principle not only to the distribution of plants according to
latitude, but also according to vertical elevation above the surface of the
earth in the same latitudes. Thus an elevation of fourteen thousand feet
under the tropics corresponds to 53° north latitude in America, and 68° in
Europe. The vegetation on the summit of Mt. Etna would correspond with
that of Mt. Washington, and this again with the summits of the Andes, and
the level of the sea in the Arctic regions. In the ascent of a high moun-
tain, we have, as it were, a vertical section of the strata of vegetation which
7

' crop out ' or successively appear as we advance towards the north over a
wide extent of country.

" But in dwelling on the resemblances between the plants of high latitudes
and those of high mountains, we must not lose sight of their not less con-
stant differences. In the northern regions in general, we find the number
of species comparatively small. Thus in the region through which we
have passed, and which has already a northern character, we find vegetation
characterized by great vigor ; the whole country covered with trees and
shrubs, and lichens and mosses in great profusion, but the species few, and
the proportion of handsome flowering shrubs small. In the Alps, on the
other hand, vegetation is characterized by great beauty and variety, and the
number of brilliantly flowering plants, of Gentianaceae, Prirnulaceaa and
Composite, is very great. The plants, however, are dwarfish, and vege-
tation comparatively scanty ; the lichens and mosses much less abundant.
There is, then, not an identity, but an analogy only, and an imperfect though
very interesting one, between Alpine and Arctic vegetation."

July ZQth. — We pursued our way this morning under the shadow
of magnificent walls of basaltic rock, with Pie Island rising in the
distance outside of us like a Gibraltar. We reached the Location
early in the forenoon, and were most kindly received by Mr. Robin-
son, the agent of the Montreal Mining Co., who have begun opera-
tions here.

A high rocky promontory, running S.W., (parallel to Thunder
Cape and the other high ridges hereabouts,) is here cut across by a
sort of fault or interval, leaving a strip of land rising gently from
the lake on either side, to a ridge in the middle, backed on the
north-east by cliffs seven hundred feet in height. The slope from
the little curved beach where we landed was shaded by scattered
trees left from the forest. Under these the workmen were busy
in putting up cabins for a number of miners who had just come
up with Mr. Robinson, and who, for the present, were living in
tents on the beach. Back of these, was a row of cabins, and the
little one-story house of the agent. Mr. R. showed us a large num-
ber of minerals collected hereabouts, and kindly offered us whatever
of them we chose to take. Among them were very brilliant speci-
mens of calc-spar associated with cobalt, manganese, and blue and
green sulpnurets of copper.

NARRATIVE. 91

Afterwards he carried us by a path running back of the house
past the opening of the shaft, through a clearing planted with pota-
toes, and a young orchard of cherry, apple and pear trees, down to
the cove on the other side of the point, whence we sailed across the
strait to Spar Island.

This island receives its name from a vein of calc-spar, some twenty
feet wide, quite pure and white, except -where brilliantly colored by
metallic salts, running across the island and down into the lake on
the other side, visible with a phosphorescent light for a considerable
distance under water. This is the locality of most of the specimens
we had seen at the office ; splendid masses of white translucent spar,
tinged with brilliant blue and green by the associated minerals. We
noticed drift-scratches on the outer side of the island, having a direc-
tion nearly E. and W.

The day was showery, with driving thundery clouds and mist,
through which we got a fine view of Pie Island, dim and majestic in
the distance. We were driven for shelter into an unfinished build-
ing of squared logs, which the company are erecting with a view to
continuing the mining operations which have of late been suspended
on the island. Such a building (about forty feet square and of two
stories,) they say can be put up in four or five days. On our way
back the weather improved, and we had a good view westward of hills
over hills towards Pigeon River, the boundary between the United
States and Canada, distant about twenty miles.

When we got back towards evening, we found the miners amusing
themselves after their day's work, by pitching, or " putting " stones,
and I was surprised to find the puny Canadians had rather the advan-
tage of the burly Cornish men. Mr. Robinson invited us to supper,
and I believe none of us experienced any of the difficulty of the
traveller, who, after a trip over the prairies, found himself, on his
return to civilized life, constantly tempted to draw his feet up into his
chair. In our case the benches were felt to be a decided improve-
ment.

After supper Mr. R. carried us into a shaft they are sinking at the
foot of the cliiF. Here we got fine specimens of Iceland spar. No
ore had as yet been sent to market from this mine, but the prospects
seemed favorable, and the whole establishment had a thriving look.

92 LAKE SUPERIOR.

July Zlth. — We had intended to cross to Isle Royale, which lay
like a blue cloud along the horizon, twelve or fourteen miles off, and
vanishing into the distance eastward. Having got outside of the
chain of islands, however, we found the wind so strong as to render
the traverse dangerous, and we accordingly landed on one of the
Victoria Islands, west of Spar Island, to wait for some change of
weather.

The beach where we landed was a mere niche cut into the side of
the cliff, which rose steeply on all sides, thickly wooded. The
ground everywhere covered with moss. Among the trees on the
bank was the skeleton of a lodge, and a birch canoe apparently in
good condition. Some playthings of the Indian children were lying
about, among others a little boat scooped out of a chip of wood, with
mast and bowsprit, precisely such as the boys make with us, and not
at all resembling the Indian canoes. The frequency of these traces
of Indian encampments, with the small number of Indians living on
this part of the lake, shows their restless, wandering disposition.

While we were detained here, the Professor made some remarks
about the theory of the formation of mineral veins by infiltration.
This theory he considered untenable, since there is an evident con-
nection between this phenomenon and some action of the walls of the
fissures in which veins are found :

' Thus at the vein we examined this morning at Prince's Location, we
found each wall of the fissures covered with quartz crystals whose axes
were perpendicular to the walls : those inside were crystals of calc-spar dis-
posed in the same way. An electro-magnetic action, (which has been pro-
posed by some geologists,) would fully account for this arrangement. If
we suppose an electro-magnetic current passing through the fissure, this may
have brought together similar particles scattered through the rock, and dis-
posed them in the manner we see. In order to settle this point, however,
it would be necessary to ascertain whether there is any constant relation in
the arrangement of substances found in veins of different localities : —
whether the minerals always follow each other in the same succession If
this be the case, it will give great probability to the supposition of an electro-
magnetic current, over that of any merely mechanical agency like infiltration.
Such an examination might probably also distinguish the cases where veins
are formed by sublimation or deposition from vapors or gases from below.

NARRATIVE. 93

Where the vein is composed of minerals not found in the surrounding rock,
the probability would be in favor of sublimation : where the minerals occur,
though in small quantities, in the rock, there the effect may have been pro-
duced by electro-magnetism. There has been as yet no sufficient investiga-
tion of this point.

" It may be remarked here that even where the vein is composed of
hydrates, in whose composition ivater occurs, it is not necessary to suppose
them deposited by infiltration, since it has been proved that hydrates may
be formed by sublimation."

We remained here until half past three o'clock P.M., when, the
weather continuing unfavorable, and even threatening a storm, we
decided to give up our visit to Isle Roy ale, and to turn our faces
homewards.

The distance of this, our westernmost point, from the Sault, was
about four hundred and forty miles by the way we came ; as we
returned, rather more.

The wind was fresh from the southward, and when we got outside
of the islands there was so much sea that the other canoe, although
within a short distance of us, often disappeared, sail and all. It was
rather a long swell for the lake, however, and we did not experience
any difficulty from it, as we were nearly before the wind. We en-
camped on an island to the southward of the Pate, in a deep bay
with steep sides, overshadowed by trees of unusual size.

July 28th. — Started before sunrise. Weather calm and pleasant.
We passed under the south-east side of Pie Island, a vertical cliff
several hundred feet in height, presenting much the same appearance
as Thunder Cape, viz : basaltic columns, across which may be traced
the marks of an horizontal stratification. These columns in some
places have fallen out, leaving hollows, like flues, in the side of the
cliff. In other places single columns stand out alone, like chimneys ;
in others, again, huge flat tables of rock have scaled off from the
face of the wall, and stand parallel and a little separated from it.
The metamorphosed strata in one place were unconformable, exhibit-
ing a sudden fault.

In the course of the forenoon several trout were caught, and the
diversity of color led to some discussion. The men said there were
three varieties, all of the same species: 1. the trout of the open

94 LAKE SUPERIOR.

lake, (truite du large,") of a gray silvery color, with inconspicuous
spots and a white belly ; 2. Those of the rocky ground, (truite
des battures,~) more yellowish, with large distinct spots ; 3. Those
of the sandy bottom, which are simply mottled. All the trout family
spawn late ; the lake trout in October, on the sandy beaches, when
they are taken in abundance in nets, and with ground-lines having
forty or fifty hooks.

The white-fish are everywhere scarce in August, (we could not
learn why,) so that the Professor found some difficulty in getting
specimens on our return. In October they spawn, on pebbly ground,
and are then taken in great numbers. They are always seined ; we
did not hear of their ever taking the hook, though I have seen one
take a fly from the surface. The lake herring spawns on similar
ground, but in November ; the siskawet in the latter part of Au-
gust. Suckers, cat-fish and sturgeon in the spring ; the sturgeon in
swift streams ; the sucker at the mouths of the rivers ; the cat-fish
on muddy flats ; the dory (Ludoperca,*) in bays.

We stopped at a little rock around which a great number of gulls
(JLarus argentatus^) were circling, and found there a few young
ones and an addled egg. The young birds were about half grown,
covered with grayish down, with irregular darker spots. None of
them could fly, but they swam very well ; indeed, as it seemed to me,
better than the old birds. They were crouched in crevices of the
rock, and we saw no appearance of nests. The egg was coffee-col-
ored, with brown spots.

A fresh and fair breeze to-day, almost for the first time. We
passed this morning several canoes of Indians, running before the
wind with sails of birch bark. About noon, in threading a narrow
passage among the islands we saw a smoke on shore, and directly
afterwards the bateau, moored at the wharf of a deserted mining
establishment, the buildings of which were still standing.

We kept on with the same fair wind until sunset, when we en-
camped on one of an extensive group of islands. As we glided
rapidly into the little cove whereVwe were to encamp, the water
shoaled so suddenly, that looking down over the side of the canoe we
seemed to be rushing against the side of a mountain. These covea
shoal rapidly and have the bottom covered with huge rounded bowl-

ders, like a gigantic pavement, whilst there are rarely large detached
rocks on the beaches, doubtless owing to the violence of the waves,
clearing out the smaller stones from the bottom, and heaping them
up on the beach, and at the same time rounding the rocks below.

We made about fifty miles to-day.

July 29£/i. — We started at sunrise, the weather clear and
autumnal ; the wind northerly. Breakfasted on a barren island ter-
raced with ancient beaches, strewn with drift-wood, all of it showing
strong action of the waves. Some logs of a foot or more in diame-
ter had been thrown to the distance of fully a hundred and fifty
yards from the water's edge, and thirty or forty feet above its level.
Soon afterwards we entered a straight, narrow, river-like channel,
some twelve or fifteen miles long, leading inside of Fluor Island and
St. Ignace, whose dark wooded sides made a purple background to
the vista. The banks were covered with birch,, presenting an unbro-
ken fringe of green ; not a glimpse of the rock, and hardly, at inter-
vals, the white line of sand at the edge of the water.

After passing through this channel we came out into Neepigon
Bay, and had to keep round to the left to a deserted mining station
at Cape Gourgan, before we could get a good camping ground.
There we found a clearing and a convenient landing place. One of
our companions two years before, in the month of October, had seen
a large party of miners set ashore here from the propeller, to open
the works. The marks of their labors, with the approaching winter
before them, were everywhere visible. Wood had been cut and
piled up ; several log-cabins built and the cracks stuffed with moss
and mud ; and the paths through the woods showed where they went
for fuel or to hunt. The ground was strewed with fur and bones of
hares, and several lynx skulls were picked up by the men. Hunting
must have formed the principal occupation of their days, since their
mining operations had not been carried further then a few shallow
pits, which doubtless soon convinced them of the fruitlessness of their
errand.

It rained hard in the night, and we were somewhat incommoded
by the leaking of our tent. '

July 3(M. — The rain continuing this morning, we did not think it
worth while to start. The Professor took advantage of the opportu-

nity to make the following remarks on the causes that influence the
outlines of continents :

" The outlines of continents are not to be considered as fixed, immovable
limits, but are variable, and dependent upon the degree of elevation above
the level of the sea. For instance, were we to depress certain parts of South
America or of the United States, even for a few feet, their outlines would be
entirely changed, and immense tracts submerged ; and vice versa, a slight
elevation would produce corresponding changes.

" The west of Asia, comprising Palestine and the country about Ararat
and the Caspian Sea, &c., is below the level of the ocean, and a rent in the
mountain chains by which it is surrounded, would transform it into a vast
gulf.

" Continents are in fact only a patch-work formed by the emergence and
subsidence of land. These processes are still going on in various parts of
the globe. Where the shores of the continent are abrupt and high, the
effect produced may be slight ; as in Norway and Sweden, where a gradual
elevation is now going on without much alteration of their outlines. But if
the continent of North America were to be depressed a thousand feet,
nothing would remain of it except a few islands ; and any elevation would
add vast tracts to its shores.

" Elie de Beaumont, who has occupied himself much with tracing the
changes wrought in continents by geological phenomena, has shown that
chains of mountains elevated at the same time agree in direction. Thus the
mountains of Scandinavia, the Ural chain and the Alps, &c. Before the
elevation of the Alps, Europe was not divided into two great climatic re-
gions. In this country the north and south direction of the mountains has
a great influence. Animals migrate more extensively, and the cold winds,
penetrating further south, influence the temperature.

" It would be very interesting to ascertain in detail the dependence of
the forms of continents on geological phenomena. I have been struck with
the possibility of this in running along the shore of this lake. The general
shape of Lake Superior is that of a crescent. But it would be a great mis-
take to suppose it bounded by curved lines. Its shores are combinations of
successive sets of straight parallel lines, determined in each instance by a
peculiar system of trap-dykes. These dykes have five general directions, and
the outlines of the shores are determined by their combinations. One of
these directions is east, 30° north. This we find in the islands off Prince's
Location, in Isle Royale, &c., and then again in Point Keewenaw and White-
Fish Point. This is cut across by one east, 20° north : these two we have

NARRATIVE. 97

seen in several places together. Another is north, a little east. Another
nearly E. to W. The last has a direction north and south, which we see in
Neepigon Bay, where are the only inlets on the lake running north and
south. Of these various sets of dykes each has its peculiar mineralogical
character."

In looking round after the lecture for some more comfortable shel-
ter than the tent, we espied a smoke rising from the chimney of a
cabin at some distance in the clearing on the hill. Going thither we
found one of the men very comfortably established on a sort of bench
before a fire-place of stones and mud which occupied one of the
corners. This was the only one of the houses that had a fire-place,
and it was in all respects in much better condition than the rest,
whether originally so, or from its remoteness having suffered less
since its erection. Perhaps part of their company left the place
when all hopes of copper vanished, and the rest then collected together
in this building, leaving the other cabins to fall to pieces.

However this may be, the signs of habitation were still fresh here,
and likewise unmistakable traces of the severity of the climate.
Not only were the interstices between the logs carefully stuffed with
moss and mud, but even the chinks between the two rooms into which
the little hut (not over twenty feet by ten in the whole,) was divided,
were filled throughout with hares' fur, large quantities of which were
also piled up in a loft above and on a rude bedstead in the further
room ; a little circumstance which told not only of cold, but also of
the listlessness and ennui of the poor devils shut up here, who could
find time to pull to pieces skins enough to make such a quantity of
loose fur. This was shown also by the caricatures scrawled all over
the walls wherever the wood would show a mark, and an attempt
apparently to make out an alphabet, some characters of which were
entirely anomalous, and if inscribed on one of the rocks, might make
work for some future antiquary. Each of the rooms had a fire-place
occupying the corner, one still in good order, the other fallen to
pieces from the softening of the mud cement. It was sad to think
of the long days and nights they must have spent here, blocked up
by the snow and crowding round the fire-places from the keen air
rushing in at the chinks of door and window. Yet they were not

destitute of provisions, as the remains of hares, and of sundry bean-
barrels marked " Montreal Mining Company," testified ; — they no
doubt had cards, and perhaps, if they were Canadians, led pretty
much the sort of life they liked best. The question of copper or
no copper might be indifferent to them, if they were mere day-
laborers, and for the rest, perhaps our commiseration was groundless.

One of the men having broken the stem of his clay pipe to-day, re-
paired it as follows ; having cut a chip from a spruce log, he whittled
it round, and cut a notch about the middle, leaving the ends connected
by a thin spindle of wood. Then after burying it for some time in
the hot ashes under one of the fires, he withdrew it, and twisting it in
his hands one side came loose, and he drew it off, leaving a tube sev-
eral inches in length, into which he inserted the stump of his pipe-
stem. I afterwards saw this repeated, and both times, I may remark,
the division of the wood had nothing to do with the annual rings, for
the piece was taken near the outside of the log.

Towards sunset it seemed to clear off, and some of the party paid
a visit to a deserted shaft, a mile or two distant, where they found
small quantities of copper associated with chlorite, which from its
greenish color had probably been mistaken for ore. In returning
they got a ducking from a sudden shower.

July 31s£. — We got off at five o'clock, the weather unsettled, and
the wind high from JST.N.W. We were in hopes to get round the
point of St. Ignace, and then keep away before the wind. The pros-
pect to windward was grand and striking. We were enclosed in an
inner sea, a lake within the Lake : St. Ignace behind us, and on
each side ridges of granite a thousand feet high. A sea of hills,
rising from the rocky islands a few miles off, one over the other to
the mountain chain far behind in the bottom of the bay. It was in
fact an epitome of all the most remarkable scenery of the lake.
The wind however increased so much that we judged it prudent to
return. Accordingly we hoisted sail, and the canoe, right before the
wind, swaying gently from side to side, like a sea-bird changing wings,
made a comparative calm by its rapid flight ; occasionally we struck
a wave as it drew back, and then some care was required to keep
from running bows under.

We encamped this time somewhat beyond the place we had left,

NARRATIVE. 99

more under the lee of the point. It continued windy and rainy all
day, the wind going down at sunset.

Aug. \st. — Started at four o'clock. Hazy, but soon cleared off,
with Avesterly wind. We stopped to breakfast at a little sheltered
cove on St. Ignace. The water here was filled for many rods with
the larva-cases of a Phryganea, in such numbers that it was impossi-
ble to dip a cup of water without bringing up several of them. The
insects themselves were flying about in swarms. This was the only
time that we met any considerable number of these insects, which
abound about the muddy flats of the lower lakes ; the clear cold water
of Lake Superior, and the pebbly bottom, are probably unfavorable
to them. We continued coasting along St. Ignace, here a continu-
ous cliff of red sandstone occasionally showing through its covering
of forest. The wind was exceedingly variable to-day, shifting sud-
denly from one point of the compass to the opposite. I think we
might sometimes have counted ten distinct directions in as many
minutes.

Neepigon is said to signify " dirty water," and to-day it certainly
deserved its name, being exceedingly turbid, and strongly in contrast
with our experience of the other parts of the lake. But whether
this is a constant phenomenon, or was an effect of the gale, I am
unable to say. The bottom, in several places where I could observe
it, was muddy, and the water unusually shallow.

We now approached the northern shore of the bay, a majestic
line of rounded hills, the highest bare at the top, but in general cov-
'ered with vegetation. A rocky cove where we stopped had been
taken possession of by the Montreal Mining Co., who had made
their mark on one of the trees, but apparently had not been encour-
aged to proceed farther. At our camping-ground this evening we
found strawberries, still unripe.

Aug. 2d. — Hazy, wind east and strong, the Fates having seem-
ingly determined that we should have head winds in whichever direc-
tion we steer.

At Turtle Island we looked for limestone, but were unable to find
any. At this place an immense trap-dyke, running east and west
across the point of the island, had tilted the sandstone 10° — 12°,
and for some thirty feet on each side of it the rock was shivered into

100 LAKE SUPERIOR.

innumerable vertical fissures, of a line or two in width, and on an
average not more than an inch apart. These fissures were filled with
calc-spar.

We had now got back to the line of our westward course, and
came this forenoon to the terraces spoken of July 15th. This re-
markable formation (see frontispiece,) consists of three main ter-
races with several subordinate ones, rising one above the other by
steep slopes. They occupy the whole bottom of the bay, (which
has here an apparent width of a mile or more,) having the slope and
curve of ordinary sand beaches, which indeed they evidently are.
The slopes and widths of each respectively are, according to the
Professor's measurements, as follows : — First the sand beach, rising
from the water 11° for about twenty yards, then for a short dis-
tance 7°. Above this a ridge of pebbles 15°, beyond which was a
belt of trees, and then a scanty growth of grass and a few low shrubs,
extending about two hundred and fifty paces, with an ascent of 6°.
From this an abrupt ascent of 20°, with a flat of fifty paces ; then an
ascent of 10° for a short distance, then sixty paces of 7°, and one
hundred and fifty paces of 5°. Then comes another steep ascent of
30° to 33° to a space fifty paces deep of 10° — 12° . Then another
ascent of 26° — 30°, succeeded by a succession of low, indistinct
terraces, and finally an ascent of 20° to the top, which is nearly
level for several hundred paces. The total height above the lake,
according to Mr. Logan,* is three hundred and thirty-one feet. It
will be seen that the whole presents a succession of acclivities in
some cases as steep as the laws of equilibrium allow, alternating with
slopes like the ordinary lake or sea beaches.

The general direction of these terraces is perfectly parallel to the
present beach, and at right angles with the sides of the bay, which
are high and rocky, and run in the same direction for some distance
inland. From the further side of the highest terrace there is a
uniform slope to a valley, apparently not much elevated above the
level of the lake, and filled by a marsh and a small pond. The ap-
pearance is that of a deep inlet dammed across by the lake. The
material is a coarse sand, with gravel, supporting a scanty covering of

NARRATIVE. 101

grass, and a few stunted spruces. The almost perfect regularity of
these terraces, rising one above the other like one side of a gigantic
amphitheatre, is very striking even at a distance, and the effect is
increased by the absence of trees, giving the appearance of a
clearing.

As the day had grown very hot we refreshed ourselves, after our
scramble up these steep sandy slopes, by a bath in the icy water of
the lake, and had to wade out several hundred yards from the
shore before getting out of our depth. On the smooth sand of the
beach were tracks of a lynx that had evidently been prowling there
since the wind fell this morning.

As we pulled out of the bay a boat was entering it at the other
side. It proved to belong to some government surveyors who were
marking out mining locations, for which it seems there is still an
active demand. They were established at the mouth of Black River,
where we also encamped this evening.

This place strikingly resembles the mouths of the Crapauds and
Chienne Rivers. A broad beach of white sand, about a mile long,
is cut through at the west by the stream. The entrance is narrow,
with a bar across it on which is five feet of water. Inside there is
a wide expansion, across which projects from east to west (the course
of the river being south,) a sand-spit in the shape of a half-crescent,
with a broad base and tapering to a point. The rapids within sight
from the beach.

Aug. 8cZ. — Rain. Held up early in the forenoon, and we started
off up the river to see some falls about two miles above. One of
the surveyors was kind enough to accompany us as guide, but the
woods were so thick, and the ground so rough along the bank, that
we kept off to some distance, where it was more open, hoping to
strike the river higher up. But after half an hour's hard work, hear-
ing the noise of rapids and coming down to the stream again, we
found ourselves precisely where we started from. We resolved
next time to keep near the river. Here we had to scramble over
rocks covered with black lichens, ( G-yropliora^) and make our way
through dense spruce thickets, but whenever we strayed away from
it we came to open desert tracts. At length we struck the river
again, and came out at about the middle of a sand bank sloping un-

102 LAKE SUPERIOR.

interruptedly to the water. The distance to the top of the bank
seemed trifling, but once embarked we found it a very severe tug, for
the average slope being 30° to 31° and the sand very loose, we slip-
ped back at each step nearly as much as we advanced. The height of
the plateau above the river here is not less than a hundred feet, and
the bank seemed to be composed of mere sand and gravel, hori-
zontally stratified. Sitting clown at the top to recover our breath,
we had before us an extensive view over the forest, through which
the river opened a long lane northward and seemed to expand be-
yond into a lake. At this spot we struck a trail leading to some
works opened a year or two since near the Falls. The supposed
copper, however, proving to be iron pyrites, they were speedily
abandoned.

We had little difficulty now in reaching our place of destination,
and came out of the forest upon a chasm of nearly vertical slate rocks,
on a level again with the river, which comes in from the northward
in a mass of rapids and little preliminary cascades, and falls in one
sheet fifty or sixty feet into the chasm, a sort of gigantic well-hole,
its sides black and savage with the splintered edges of the slate-
rock, and so steep and even overhanging that we could not from
any position get a view of the bottom. Below, the stream turns
sharply to the left and rushes out through a deep gorge not more
than five or six yards wide at the bottom. From below the gorge
there is a very wild and picturesque view of the river boiling out
from between overhanging rocks.

On our way back we followed the miners' trail all the way to the
lake, coming out about a mile to the eastward of our camp. In
our course we had diverged considerably from the river, and found
the ground much more open, the trees scattered so much that we
sometimes had difficulty in tracing the line which was " spotted"
or scored upon them ; the ground dry and lichenous. We descend-
ed to the lake by a succession of well-marked terraces of large rough
pebbles, and then through thickets and over irregular broken rocks
in piles smoothed by a treacherous covering of moss.

In the evening the Professor made the following remarks upon
the terraces and the drift formation about the lake :

NARRATIVE.

.

" We have seen at various points along our routev4arge_aecumulations of
loose materials, often in the form of terraces. These loose materials are
usually called ' drift,' but it is necessary to distinguish among the vari-
ous formations known by this name, the beaches thrown up by the lake
upon its present shores, and the ancient terraces above the present level of
the water. Nevertheless, the connection between these two kinds of drift is
such as to show that the latter also were formed by the lake, but under dif-
ferent circumstances from the present beaches. The first question is, whether
the lake was anciently higher ; the elevation of the ancient terraces having
been the same as now ; or whether the land has been elevated. Either is
possible, for we have examples both of elevation and of depression going on
in our own day, as upon the eastern coast of Sweden and the western coast
of Norway. This question cannot be settled by a simple inspection of the
terraces, but only by a comparison of their elevation with the level of the
surrounding region. Now the terraces we saw yesterday show a difference
of level of over three hundred feet above the present lake beaches. If we
add this to the present level of the lake, and suppose it formerly to have
stood at the height which they now exhibit, it must have overflowed the
whole United States and joined the ocean. But if this were so, we ought
to find the remains of marine animals here, which is not the case. It is
more probable, therefore, that the land has been elevated.

" The foundation on which these terraces rest is uniformly rounded and
scratched rock. During our whole journey we have nowhere seen serrated
peaks ; everywhere the surface is smooth, grooved and scratched in a north
and south direction, occasionally diverging east and west. And it is evident
that the force that produced these appearances acted from north towards the
south, for we generally find the south side of the rocks rough and precipi-
tous, showing no abrading action, whereas they are smoothed off towards the
north. Now it may be asked whether the loose materials before spoken of
were the agents that produced these effects ? I think we may say positively
that they were not. We have found the rounding and grooving at the
highest point we have visited, that is, over twelve hundred feet above the
level of the lake. This is much higher than any of these loose materials
are to be found. Moreover we see they are disposed according to the pres-
ent form of the lake, and evidently in many instances have been heaped up
by a force acting in a direction from south to north, directly contrary to that
of the grooving force. It is clear that the formation of the terraces was
subsequent. They overlie the grooved and rounded rocks.

' To ascertain the cause of this latter phenomenon we must find what are
its limits. Now we find it occurring universally over the northern portion

104 LAKE SUPERIOR.

of the globe, and always having the same general direction. Its limits in
elevation, as ascertained on the sides of mountains, is about five thousand
feet above the sea. At about this height on Ben Nevis in Scotland, and on
Mt. Washington in New Hampshire, the grooving and polishing ends. Be-
low this level the whole northern surface of the earth as a general thing
shows the marks of this agency. Some geologists attribute these effects to
the action of currents. But currents extending over such a vast extent of
the earth's surface must necessarily have been ocean currents, and these
must have brought with them marine animals, of the existence of which no
traces have been found. Moreover such extensive currents in one direction
could not have existed : there would necessarily have been refluxes and
counter-currents.

These and other difficulties have led me to attribute these effects to an-
other cause. It has been ascertained that the glaciers of Switzerland formerly
extended much farther than at present, reaching, without interruption, to
the vicinity of Paris, and, near their origin, to the height of nine thousand
feet above the sea. Similar indications are to be found in all the mountain
chains of Great Britain, and in various parts of Europe. Now at the time
when such glaciers existed in Europe, the temperature must have been
much lower than at present. The mean annual temperature of Switzerland
must have been 15° Fah. below the present. That such a depression of
temperature actually took place is also indicated by other facts. Thus the
fossils found in the glacial moraines are of an arctic character, and shells of
the German Ocean are found in the moraine gravels of Sicily. This, how-
ever, is inconceivable without a corresponding depression all over the globe.
Now if we suppose the mean annual temperature of this country to be
reduced to 26° Fah., it would naturally be covered to a considerable depth
with ice, which would move from north to south. Such a mass of ice mov-
ing over the country would produce these effects of rounding and scratching
the rocks, and would remove the soil, except from the depressions. It is
sometimes objected to this theory that we have here no slope which should
cause such a mass of ice to move onward. But it is not necessary that
there should be any slope in order that a glacier should move. In the
Swiss glaciers the motion is often slowest on the steepest part of the slope,
and some glaciers of 7° inclination move faster than others with a slope of
40°. The great motive force is not the gravitation of the mass, but the
pressure of the water infiltrated into it. Then supposing the country to have
been subsequently depressed, (as we see has been the case in Sweden and
Norway, where marine shells have been found at the height of three or four
hundred feet above the level of the sea,) and afterwards raised again, these

NARRATIVE. 105

various terraces would mark the successive paroxysms or periods of reeleva-
tion Such a depression would not cause an irruption of the sea, since the
level of the lake is over six hundred feet higher than the sea-level. But
these phenomena are exceedingly complicated, and cannot be sufficiently
illustrated without further details.

" The east and west direction of the scratches at Spar Island, contrary to
the general rule, I suppose to have been caused by the depth of the chan-
nel there, giving the glacier on its retreat a direction parallel to the shore of
the lake. We had there two very distinct systems of striaa, one much more
southerly in direction than the other. Probably the glacier when advancing
from the north, having an enormous thickness, disregarded the shape of the
ground over which it passed, but on its retreat, that is, when it began to con-
tract, having meanwhile melted away considerably and thus become lighter,
its direction would be more easily modified. Similar phenomena are ob-
served in the present glaciers in Switzerland. In a little loch near Ben
Nevis there is also a secondary system of scratches, at right angles with the
general direction, which may be traced even on the bottom of the loch."

We learned from the surveyors that a brown bear, differing -from
the black and grizzly bears, is found in this region. It was said to
be about the size of the black bear, and is probably the barren-ground
bear, ( Ursus arctos americanus,') of Richardson, though he says this
species is not found so far south.

On coming out of the tent we observed that standing by one of
the fires, so as to bring it between us and the rapids, the roar of the
water was suddenly shut off, as if by a door, the sound being inter-
rupted no doubt by the ascending column of heated air.

The weather looked threatening this evening, and in the ni^ht we

C2 O ' O

had a violent shower accompanied by thunder and lightning. In the
midst of one of the gusts we were awakened by several small rivu-
lets playing down upon us from folds in the tent, which, on account
of the sandy soil, was not properly stretched. Indeed, without some
better contrivance than mere loops for the tent-pins, a tent like
that we had cannot be stretched so as to be water-proof in a vio-
lent shower. One of the tents, brought by Mr. Marcou, of the kind
used by the French officers in Algiers, was entirely water-proof, and
in every way more convenient than ours. It was square, with nearly
perpendicular sides, and stretched near the top by cross-pieces at
8

106 LAKE SUPERIOR.

right angles with each other, while the pole ran up in a point in the
middle. The only help was to cover ourselves as far as possible
with our water-proof cloaks, &c. But these in the pitchy darkness
were not so easily found. We then attempted to light a candle,
but the matches were damp, and with all our precautions could not
be coaxed quite to the igniting point. Finally by the intervention of
a flint-and-steel, (let not the traveller be seduced into placing his
reliance in any new-fangled substitute for this trusty companion,)
we managed to get a light and find our things, and therewith made
ourselves tolerably comfortable.

Aug. 4:th. — Weather still unsettled, and we did not start until
after breakfast. It was calm at first, but the wind soon rose strong
from the N.N.W., obliging us to creep round very near the shore.

We encamped at night on a 'point where the very wide and steep
beach ascended by terraces to a long regular ridge. This ridge was
covered, in one place in an unbroken patch of an acre or more, with
a checkerwork of large tufts of yellowish gray and dark pinkish
lichens, mingled with deep green jumper (J. virginiana^) and Vac-
cinia.

The beach was covered with drift-wood, large trunks of trees with
the roots often attached, most numerous on the top of the beach
close to the trees, although the distance from the water must be a
couple of hundred yards, and the elevation not less than thirty or
forty feet. We never met with any floating wood. Doubtless the
trees are washed away and thrown up in the winter, and cast higher
by each successive storm until they are out of the reach of the water.

The Professor found here, in place, the red porphyry of which we
had found erratic blocks at many points to the southward on our way
hither ; it was perfectly stratified, and associated with chlorite.

Aug. btli. — We reached the Pic early this morning. As we ap-
proached the wharf we saw our companions whom we had left behind
here, waiting to receive us. The sick man had pretty nearly recov-
ered, but still looked thin and pale.

In the low grounds here, as at Fort William, we found partridges,
(^Bonasia umbellus ;) in the wettest part of the swamp, directly at
the foot of the ridge, I came upon a female with a brood of young

3

NARRATIVE. 107

nearly fledged. It is remarkable that this bird which with us affects
dry situations, about the lake seems, as far as our experience went, to
prefer swamps; the spruce-partridge (Tetrao canadensis,*) being
found rather on the high ground. But this apparent anomaly is ex-
plained when we remember that in the White Mountains, for instance,
where both species are also found, the spruce-partridge is met with
only at considerable elevations, among the spruces or " black growth."
from which its popular name is derived, and the other bird in the
valleys or lower slopes. But here, where the spruces come down to
the general level of the country, the difference of distribution is still
expressed, though less distinctly, notwithstanding it necessitates a
change in what would seem a more important point. In this instance
a very decided habit of the bird is sacrificed to what many natural-
ists would call a mere abstraction.

In the night we were disturbed by the dogs, who swarmed as usual
about the Indian lodges, and as usual were half-starved and depen-
dent solely on their own exertions for support. A camp-kettle left
outside of the tents attracted them into our neighborhood, and they
made a great noise in rolling it over in their endeavors to get the
cover off. Among this vagrant crew I was astonished to see Mr.
Beggs' Esquimaux dog, who might be supposed to be too well fed to
be tempted into such ways. This dog was said to be of the pure
breed. He was of a yellowish-white color, of moderate size, with a
small head, the nose pointed and the face rather wolf-like, though
not at all savage in its expression. Round the neck was a ruff of
hair, and the tail was bushy and curled upon itself, as we see in the
representations of this species.

Any. tith. — Mr. Ballenden stopped here at sunrise this morning,
on his way to the Red River settlement, of which we understood he
had been appointed governor. He had come all the way from Otter
Head this morning, a distance of forty or fifty miles, running before
a strong S.E. breeze in his large two-sailed boat. But this wind
which was so favorable to him was quite the reverse to us, and kept
us degrades here until six P.M., when, there being a slight lull, we
embarked.

Mr. Swanston had promised to send us up some provisions hither
from Michipicotin, but they had not arrived, and the stock in the

108 LAKE SUPERIOR.

store-house was so small that Mr. Beggs at first thought he could not
spare us any, but just before we left, taking compassion on our desti-
tute condition, he gave us a supply that would last us to Michipieotin.

When we got outside of the bar the wind rose again. We soon
lost sight of the bateau, and the two canoes kept on alone as well as
they could against the wind and sea. We in the larger canoe could
not help watching with some anxiety the other one under our lee,
occasionally throwing half her length out of the water, and then
pounding down so as to make it fly up on all sides. This thumping
does not agree very well with the birch bark. The gum gets cracked
and lets in the water, and there is not substance enough about the
fabric to float when filled. It was fast growing dark, and the shore
to leeward showed a horrid line of grim weather-beaten rocks and white
breakers. At length the men in the other canoe called to us that
they could stand it no longer, and kept away for a cove we had just
passed. We followed them, but although only a few hundred yards
behind, yet it was so dark that when we entered the narrow mouth of
the bay, we could see nothing of them. The outline of the shore to
leeward, however, was still distinguishable against the western sky,
and we assured ourselves that they had not gone further to leeward.
We kept, therefore, an anxious lookout as we ran rapidly up the
narrow bay, so narrow that we could not pass them undiscovered if
they were afloat, and fired off several guns, but without answer.
Before long we came to what seemed the bottom of the bay, but here
we found no signs of our companions, and seeing a further passage
to the left, we supposed they had kept on. Accordingly we pushed
on up a river-like inlet, with high mountainous ridges on each side
half a mile or more before we came to the bottom.

Here we landed on a little sand-beach, heaped up with a great
quantity of drift-wood. While the men were pitching the tent in an
open space inside the fringe of bushes, we lighted a fire, and looked
about with a torch made of a roll of birch-bark for a tree suitable for
a signal-fire. We soon found a tall spruce well covered with lichen,
and applying the torch below, the flames climbed and spread upward
and horizontally from one branch to another until the whole burst
upwards in a vast tongue of flame, crackling and whirling up sparkles
of burning twigs and leaves to such a height that it seemed impossi-

ble that our friends should be in the bay and not see it. But the
flames went out, the last sparks one after the other dropped away,
and the dark walls of the bay came into sight against the sky, yet
we listened and looked in vain for an answering signal. Next morn-
ing, however, namely :

Aug. lilt — We were early awakened by their voices on the beach
They had landed in the outer cove, and thus did not see our fire,
being cut off by a high intervening ridge. They had heard the
gun, but were engaged in hauling up the canoe, and so could not
answer it. Looking round upon the prospects of the day we found
the wind still so strong from the S.E. that there Avas no chance of
getting off at present. Of this we could feel no more where we
were, than if we had been at the bottom of a well, but the men
pointed to the breakers at the mouth of the bay, where, at the dis-
tance of a mile or more, the large and rapidly shifting masses of
white against the black rocks showed that the surf was beating
outside at least as violently as the night before. On listening, the
roar of the waves could be distinctly heard. But immediately
about us it was dead calm, with occasional eddies in the tree-tops
from all points of the compass. A contrast such as the lake seems
to love, as if it sought to break up the uniformity of its general
features as much as possible by brisk and abrupt changes in the
minor ones. Thus although the weather throughout our journey
might be called settled, yet we very rarely had a steady wind,
either as to direction or strength, and in the hottest day the shade
of a rock, or a cloud passing over the sun was enough to make it
cool. The range of clothing thus necessitated within the twenty-
four hours was extraordinary.

•/

Our little point was as silent as a piece of the primeval earth ; not
a living thing stirring except a few musquitoes, and an impudent
moose-bird that perched down, with a jerk of the tail and a knowing
turn of the head, among our very camp-kettles. A heavy stillness
seemed to hang over it and weigh down every sound, so that a few
paces from the tents one forgot that he was not alone. It was as if
no noise had been heard here since the woods grew, and all Kature
seemed sunk in a dead, dreamless sleep.

110 LAKE SUPERIOR.

Yet it was clear we were not the first visitants, for the fire-weed
had sprung up here, and close at hand we found lodge-poles, and
the remains of fires. Here also was an Indian sweating-house; a
skeleton dome of sticks, about four feet high and two in diameter.
The patient squats inside, and by his side are placed some hot stones,
on which are thrown various herbs, bj way of " medicine." Then
the whole is covered in with blankets and pieces of bark, and he is
left to simmer for the requisite period.

Back of this a path led a short distance through the woods to the
mouth of a sluggish stream some five or six yards wide that joined
the bay north of our camp, which was thus cut off on three sides by
it and the lake, and on the fourth by the mountain.

Our beach, as I said, was heaped with drift-wood, most of it arbor-
vitte, recognizable by its twisted stem. This tree loves the water,
and grows in situations where it is most exposed to be washed off
by the winter storms. Some of the logs were of large size, a foot
or more in diameter, completely stripped of branches and bark, and
in general of their roots, and exhibited marks of very rough hand-
ling, being deeply grooved and rubbed, perhaps by chafing together,
partly perhaps from ice. Many of them were very regularly and
smoothly tapered at the end. Driven into the bay by the westerly
gales in the winter, they had doubtless drifted along its steep sides,
and been successively piled up at the bottom.

Our men having such a store at hand did not spare fuel, and
were mightily amused when we told them they had on five dollars'
worth at once. But although cold morning and evening, it was
very warm in the middle of the day, the temperature rising from
about 40° to near 80° Fah.

The water was deepest close to the rocks at the end of the
point, though even there it was hardly anywhere more than five
feet deep. Beyond, it was so shoal that we very easily waded
across to the other shore, about a quarter of a mile. The bottom
was an even surface of mud, on which we met one or two large
rounded pebbles half imbedded, but no sand or small stones. Vari-
ous water-plants, namely, two species of Potamogeton, and an Echi-
nodorus, with pretty white flowers, were growing abundantly here.

NARRATIVE. Ill

The wind and waves still high outside. Several times the men
went to explore, but returned, reporting it still too rough to venture
out.

Aug. 8th. — This morning we heard distant reports of guns, and
the men thought it might be our friends of the bateau over in the
next bay. As our provisions were getting very low (the bulk of the
stores being as usual in the bateau,) they resolved to cross the ridge
and fetch a supply. They reached the cove after a laborious climb,
but found no traces of them, and so kept on to the Pic, where they
found them reestablished in their old quarters.

We now reconnoitred again, but with the same results as before.
Towards evening, however, the men seemed to have made up their
minds that we should get off to-morrow. Certainly "laviette" the
old woman, as they called her, (a personage corresponding to our
" clerk of the weather,") had given us a long enough bout of it, and
it was time to expect a lull. Accordingly, they made all their pre-
parations, and being desirous no doubt to appropriate to themselves
the largest possible share of the good things of the wilderness, piled
such a huge quantity of wood upon the fire that we were driven back
yard by yard to the distance of some rods.

Aug. 9th. — Calm, with a slight fog, and soon cleared up very
warm. This afternoon, for the first time on the lake, the wind was
strong from the south. We encamped in a cove under a hook pro-
jecting from the southward. The beach of large stones covered with
lichens, whence the name of Campement du Pays de Mousse,
which the cove bears. It is terraced up to a dividing ridge, and
thence clown in like manner to the lake on the other side.

We had been struck for some distance back, and particularly to-
day, with a falling off in the luxuriance of the vegetation, as com-
pared with the country further north. This may be owing to the
greater exposure to the northerly winds ; the more northern shore
being protected on that side by a lofty and continuous barrier. In a
very sheltered cove where we landed to lunch, the trees were of con-
siderable size. One larch measured seven feet two inches in girth,
three feet from the ground, and we judged its height to be at least
sixty feet.

112 LAKE SUPERIOR.

Aug. ~LQth. — Calm this morning, with a swell on the lake ; an
unusual occurrence, owing to the southerly wind of yesterday. We
passed at a short distance the river Rideau, which falls in a succes-
sion of cascades (said to have ninety feet descent in all) directly
into the lake. The final fall, of about thirty or forty feet, is divided
in the middle by a large rock, part of the wall of the cove into which
it falls. This river, the only one we saw where the never-failing falls
descend directly into the lake, was also the only one that had no
sand-beach at its mouth. All the others were indicated from a dis-
tance by an expanse of white sand.

Shortly after, the wind sprung up fresh from the south-west, of
which we took advantage with our tarpaulin sails. It is a mistaken
notion that a canoe will not sail on a wind. Ours sailed very well,
with the wind somewhat forward of the beam. Only the sails are
not braced up much, but just enough to keep full ; since otherwise,
having no keel, the canoe would make too much leeway.

Opposite Otter Island we counted ten parallel trap-dykes, running
north, twenty-five degrees west. Here are several terraces, passing
by regular gradations into the present beach. At the Riv. a 1'Ois-
eau Vert are veins of epidotic trap. The bateau hove in sight out-
side of us this morning, with both sails set.

In the afternoon we came upon the bateaux from Michipicotin,
moored under the lee of some rocks. They had been several days
on the way already, being kept back by the wind, and thus it was
that our stores had not arrived at the Pic. These were now handed
over to us, consisting of pork and excellent ship-biscuit. The men in
the boats were mostly half-breeds, with their families. Several of
the women were very pretty ; their complexion, indeed, a faded or
bleached olive, as if they had never seen daylight, but with a spot of
color in the cheek. We passed Michipicotin Island, having neither
time nor favorable weather for visiting it, and encamped on a beach
of coarse dark sand, where we observed the white flowering raspberry
for the first time on our return.

Aug. llth. — At half past five this morning when we got under
weigh, it was dead calm and somewhat foggy. The fog soon lifted,
and the sun shone out warm. The surface of the lake continued

NARRATIVE. 113

unruffled, reflecting, unbroken and scarcely dimmed in color, the
full form of every rock and tree. Running along at a moderate dis-
tance from the shore in this calm weather, we were often struck by
an apparent convexity of the surface, as if the water were higher
between us and the rocks. It even seemed to hide the line where
land and water met.

Suddenly the water was spattered by the rising of a shoal of lake-
herring, and our men were immediately full of excitement, and' must
needs get the fish-spear from the bateau to have a stroke at them.
By that time, however, the shoal had sunk again, and the men
watched in silence and without dipping an oar, for them to rise.
Looking down over the side of the canoe, we could trace the vast,
simple lines of the rock, until lost in the green mist. Everything
below the surface seemed to shine with a diffused phosphorescent
light, like a green unclouded sky. All at once the shoal came in
sight, under the boat, pressing steadily on with a broad front, a soli-
tary white-fish rather in advance of the rest. Each kept his relative
position to the rest, like a flock of waterfowl, and they glided easily
onward without any apparent exertion except a tremulous motion of
the tail. Yet they soon vanished ahead, and not long after a great
trout came sullenly following in their wake, like a pirate hovering
about a convoy of merchantmen.

Some Indians came off to sell us fish, and our men in their gossip
discovered they had in their lodge a couple of young foxes, which
the Professor thereupon demanded to see, and bought. The poor
little fellows were about half grown, and seemed to suffer from the
heat. The first thing they did when we took them aboard, was to
seek out the shadiest corner. They appeared to be perfectly tame,
or at least inoffensive.

We caught several trout ourselves in the course of the forenoon.
I was struck with the life-like appearance of the bait, (a trout's
stomach drawn over the hook, and tied to the line above,) visible at
a great depth. Out of water it has rather a shapeless appearance,
but jerked along at a sufficient depth it has precisely the look of a
small fish that has been wounded, so as swim with difficulty and
somewhat sideways.

In the afternoon a favorable breeze sprung up. Our men were

profuse in their thanks and compliments to the " old lady," and in
addition to the tarpaulin, must needs rig a spritsail, which they made
of a blanket extended between an oar and the fish-spear.

We reached Michipicotin at about five P. M. One of our first
questions was as to the flies. Mr. Swanston said they were " all
gone," which we found, comparatively speaking, true, but at the old
camping-ground there were a few left to remind us of our former
sufferings.

We held a council this evening as to the advisability of making an
excursion to Michipicotin Falls, six miles up the river. The majority
were decidedly in favor of pushing on, and the Professor did not like
to leave -them. So it was settled that two of us who wished to go,
should remain behind with the small canoe, and endeavor to overtake
the rest by forced marches.

On opening this evening a tin case in which bird-skins were packed,
I found the inside covered with drops of water, and some of the skins
so wet that I had much difficulty in drying them. As the case was
surrounded by an India-rubber covering, and the whole put into a
wooden box, which was perfectly dry, the moisture could have come
only from the condensation occasioned by the great and sudden
changes of temperature. Metal, therefore, is to be avoided here, if
dryness is requisite.

The dogs disturbed us somewhat in the night by their antics with
a frying-pan and a tea-kettle, which Henry had unfortunately omitted
to place out of reach. A troop of mongrel curs seems to be a gene-
ral characteristic of an Indian village, though they neither make use
of them nor seem to take any care of them,* and one does not see
why they should keep them, unless it be for an occasional dog-feast,
an observance which, to judge by the lean condition of the dogs, is
rather gone out of fashion.

Aug. l^th. — Warm and cloudy. While our friends were making
ready for departure, we set off for the falls, with an Indian lad for
guide, paddled a few hundred yards up the river, and having pulled
the canoe up on the scanty beach on the opposite side, climbed up

when he understood that the skeleton only was wanted. Whether this was from any
feeling for the dog, or only from some superstition, we could not learn.

the steep sandy bank, twenty or thirty feet high, and found ourselves
upon a wide plain, bounded by the river on the right, and some steep
rocks in the distance, on the left.

The surface was level and barren, not a tree in sight, but only a
uniform expanse of withered herbage, bearberry, lichens and great
quantities of blueberries and huckleberries, now ripe, much to our sat-
isfaction, for we had not tasted fruit of any sort for so long that even
these humble kinds had a flavor unknown before. There were two
sorts ; the most abundant was of a light lead color ; the other larger
and of a dull blackish. We did not stop to gather them however,
but pulbd them by handfuls as we ran along the trail, to the an-
noyance of our little Indian, who had evidently calculated upon a
deliberate feast.

The path was worn through the crust of superficial vegetation
and the thin seam of mould that supported it, a foot deep into the
sand below, and so narrow that we had to walk Indian fashion with
toes turned in, and I had some trouble to avoid grazing my ankles
with my shoe-soles. My companion wore moccasins, a much more
comfortable gear for this ground.

The weather was very warm, and the flies exceedingly trouble-
some, rising in swarms from the blueberry bushes when we touched

O */

them. Whether from a presentiment of their coming end, or from
some other cause, they were not flying abroad to-day, but collected
on the ground. Once roused, however, they showed no backward-
ness in making an attack. Having for the first time open ground
enough to observe their manocuvririgs, we tried to outrun them,
and easily left them behind, but in a short time the swarm, like a
pack of wolves, and guided to all appearance in like manner by
scent, came ranging up in a body and fell on afresh.

Continuing on for about a mile we came to a sudden depression in
the plain. We stood on the edge of a steep bluff some forty feet
high. Below, the broad level valley stretched off apparently to the
river on the right, and on the left to some rocky hills several miles
distant. It seemed perfectly level and sandy, and in all respects
like the plateau on which we stood, except that it was still more
barren and showed patches of bare sand. On the opposite side the
bluff rose again as abruptly to about the level at which we stood.

116 LAKE SUPERIOR.

It had all the appearance of a sudden and even depression across
a previously unbroken plain. My companion thought it a former
bed of the river, and that he could see an opening in the hills to
the left (which direction we knew the river took above) through
which it might have flowed. I could see nothing of this, nor did
the valley seem to me to present the appearance of a river-bed, for
it was perfectly level, free from stones, and nowhere less than half
a mile wide, varying from this to perhaps three fourths of a mile, at
least six times the present width of the river. In our haste nothing
very satisfactory could be made out, but my general impression was
that it was the bed of a former arm of the lake.

Crossing the valley and ascending the bluff, by an equally steep
path on the other side, we came before long to scattered spruce
trees, and at the distance of about three miles from the factory, to
the river again. Here, we were made aware that what had seemed
to us a horizontal plain, was in truth a gradually ascending level, for
we now stood sixty or seventy feet above the stream. A little brook
scarcely deep enough to swim a trout came into the river here at
the same level, having sawed through the sand to its very base, leav-
ing on each side a steep slope of pure sand, excessively fatiguing to
ascend. We were now surrounded by a tolerable growth of spruce
and birch, occasionally forming thickets. The aspect of the coun-
try was not unlike that of the White Mountains at the elevation at
which the forest begins to disappear, only more abounding in lichens
and small shrubs.

There was no opportunity in the course of our hasty walk to ob-
serve the stratification of the sand. We saw no freshly broken sur-
faces, and in the paths the materials were of course displaced. In
general terms, however, I may say that it was a coarse, reddish sand,
mixed with gravel and with a few stones, which were somewhat
rounded but not scratched as far as I observed. The general ap-
pearance was much the same as that of the bluff at th« factory,
which is very distinctly stratified.

Afterwards we came out into an open space whence we had a
very extensive view over woods and barren ground, with occasional
glimpses of the river far below, and on the edge of the horizon a
peep of the lake.

NARRATIVE. 117

About three quarters of a mile from the falls we struck the
portage path, running through deep moist woods. Across it were
laid logs, at short distances apart, so that it was like walking on a
railroad where the sleepers have not been filled in. An explanation
soon presented itself, in a smooth, narrow trench in the middle of
the path, such as would be made by the keel of a vessel, and on
each side the traces of a heavy body dragged over the ground ;
we conjectured that it was an arrangement for facilitating the trans-
port of the heavy bateaux that come down from Hudson's Bay.
When we reached the head of the portage we found we had guessed
rightly, for here lay several large boats ready to be hauled across.
These bateaux measure generally twenty-eight feet in the keel and
near forty above, and are very heavily built, yet as Mr. Swanston
afterwards told us, the voyageurs make nothing of the portage, and
amuse themselves with racing the boats against each other over
the path.

At the head of the portage we found ourselves a good way
above the falls, but there was no appearance of a path, so we made
our way down stream through the tangled arbor-vitaes, and soon
came out in front of the upper fall.

Michipicotin Falls consist of three cascades of about equal heights,
separated by short intervals of rapids ; the total descent is upwards
of eighty feet. At each fall the river is compressed to the width
of a few yards between projecting points of rock, and below each
expands again somewhat.

The rock is a gray sienite, broken into huge parallelograms, some
lying about in loose fragments, in others, the cleavage lines indi-
cated on the face of the rock having a dip of about 20° southwest,
that is, at right angles with the fall. These projecting points and
detached fragments of hard rock in the bed of the cascade, give it a
peculiar character. Thus at the foot of the second fall the whole
mass of water is thrown upwards again in a vast fountain of spray,
from the resistance of some obstacle below the surface.

The third or lower fall is very striking. Whether from the sudden
expanse of the channel, which becomes somewhat wider here, or
from the shape of its bed, it forms a regular half-dome of broken
water, a most magnificent spectacle, not at all like any other large

118 LAKE SUPERIOR.

fall I ever saw, but resembling on a gigantic scale the bell of water so
often formed by a projecting stone in small mountain streams.

This indeed might serve for a description of the whole scene. It
is a mountain torrent on a large scale, and without the majesty of Ni.
agara, or even of Kakabeka, it has a charm of its own in its exuberant
life and freedom. Below, the river turned to the right, leaving at its
outer angle a whirlpool, in which were revolving a great quantity of
logs, as cleanly stripped of bark, roots, and branches, as if prepared
for the saw-mill.

From what I could observe, the river-bed above the falls is not
much below the general level of the country ; as if it flowed there
over a rocky plateau, covered with a scanty depth of soil, and
abruptly falling away at the falls, forming a barrier against which
the sand and gravel from the lake have been heaped. Below, the
banks are high, of loose drift deposit. This may be the edge of a
step in the descent from the height of land.

Reaching the factory again, we found all in readiness for depart-
ure, the men anxious to be off, and the lake so smooth that we could
take the direct line for Cape Choyye, which we reached a little after
sunset, while the air was still full of rosy light, the moon just peep-
ing through the fringe of forest on the edge of the cliff above us.

Here the men proposed to stop for rest and refreshment, and then
to keep on by moonlight.

At the place vwhere our tents had been pitched, I found the ever-
green boughs still undisturbed on the stones ; the balsam twigs still
retained most of their leaves, but the spruce were entirely bare.
We hastily drank our coffee, and the men their tea, and then reem-
barked. About ten o'clock we were awakened by the cessation of
motion, and found ourselves in a narrow cove near Cape Gargantua.

Aug. loth. — It was warm and rainy this morning, with fog. We
started early, and approaching the Riviere aux Crapauds, the men
saw a boucane, namely, a smoke (whence, bye the bye, the term buc-
caneer'), and said we should find our friends there, though we could
not well distinguish it from fog. They were right, however, for
there they were, just done breakfast.

I was struck with the unhesitating accuracy with which our men
steered in the fog to-day ; they evidently knew the way now, though

' NARRATIVE. 119

f

by no other landmarks than rocks and islets, which to an ordinary
observer seemed all alike.

In the afternoon it rained hard. We protected ourselves with the
tarpaulin, elevated in the middle with a tin map-case by way of tent-
pole. The rain stopped towards evening, and close before us lay
Mica Bay, with its wharf and crane, and Capt. Matthews' cottage
on top of the bank.

The Captain had gone to commence mining operations at Michipi-
cotin Island. Mrs. Matthews, however, and Mr. Palmer, a young
gentleman attached to the establishment, received us most hospita-
bly. Mr. Palmer gave the Professor several valuable specimens,
and showed us the commencement of a very elaborate survey of the
location, in which even the trap-dykes (which here intersect at some
points in the most intricate manner,) were laid clown.

Aug. 14^A. — Before starting this morning, Mr. Palmer carried us
up to the mine to see some " pot-holes," that had been discovered
there since we were here before. The spot where they are found is
two hundred feet above the present level of the lake, in a narrow
vein filled with rolled pebbles and gravel, lying directly over the
lode which is now worked. This vein runs vertically through a con-
siderabje thickness of unstratified drift, with angular bowlders, and
scratched, but no rounded pebbles. The rock slopes steeply towards
the lake, and some of the holes are joined together like stairs, the
stones that formed them having evidently worked by degrees down
the slope, as we see them doing now at Cape Choyye.

We left with a favorable breeze, passed Marnainse, and were
already expecting to reach the Sault to-day, but by the time we were
abreast of the Sandy Islands, it blew so hard that it was thought pru-
dent to put in and wait for a lull, the bay beyond being, according
to the men, a dangerous place in foul weather. The other boats had
disappeared ; the bateau to windAvard, the canoe working in shore
towards Goulais Point.

On the broad sandy beach, as we landed, we found the tracks of a
fox, just made, for the wind had not filled them up. I set out to
explore the island, without my gun, however, contrary to my wont,
having unluckily left my powder in the other canoe. As I approached
a fallen spruce tree that lay about thirty yards off, with its top in the

120 LAKE SUPERIOR.

water, I saw coming towards me from on the other side — a fox !
The fellow was of the variety called " Cross Fox," lean and hungry-
looking. He trotted leisurely on, as one sees a dog trotting along a
pathway, — occasionally pausing to sniff at a dead craw-fish. I did
not attempt to hide myself, but stood perfectly still. He came care-
lessly on, and cleared the tree with the lightest and gracefullest of
leaps, but his black paws hardly touched the sand before he had
whisked like lightning from his course, and disappeared in the wood.
As the island is not a mile long and only a few hundred yards
across, it was a matter of wonderment how he got here, or what he
could find here to live upon. The men said he had most likely come
across on the ice from the main land (a distance of about four miles)
in the winter, and had not dared to swim back again. We found
marks of digging in various parts of the island, and conjectured he
had been reduced to a partly vegetable diet. If he could have
trotted undisturbed a few rods further, he would have found what I
picked up in his stead, the dead body of a little warbler that had
evidently been beaten down and drowned in the storm the day
before, and lay on its back on the sand at the water's edge, the wings
a little open, quite fresh, and the plumage hardly ruffled.

At dusk, two figures appeared on the beach of an island about
half a mile off. Our men said they were "Frangais," that is, not
Indians,* but more could not be made out. They proved afterwards
to have been some of our friends of the bateau, but they had
encamped on the opposite side of the island, and did not see us. It
rained at intervals, and blew very hard in the night, the wind shift-
ing from north-west to north-east. We had fears for our tent, but for-
tified ourselves by felling a few trees to windward.

Aug. 1.5th. — At five o'clock this morning it still blew hard,
and although the wind wa^ more off shore, and the waves accordingly
not so high, yet the rollers were plunging along the beach with a vio-
lence that rendered embarkation somewhat hazardous. But we were
all anxious to be off. To-day was the day fixed for reaching the

this, one morning we found on a beach where we landed, tracks of men who, they said,

Sault, and we could reach it easily from here. Our men were as
eager to be gone as we, for they had worked long enough at one job
to be glad of a change. Then at this season it was as like as not to
blow for a week, and harder, and our provisions would not hold out
many days.

So the canoe was set afloat, and held head to sea by a man on
each side, standing up to his middle in the water. In this position it
was carefully loaded, and we got on board over the stern. Finally
the men contrived to get in and push off without serious accident,
though not without shipping a good deal of water. As the wind
was directly off shore, matters improved as we proceeded, and before
long we were under the lee of Gros-Cap.

The thickets of white flowering-raspberry were now full of fruit ; the
berries averaging about three quarters of an inch in length, by two
thirds in diameter, and rather firmer and more symmetrical than
the common cultivated species. The taste is slightly acid, but
agreeable. Probably they were not entirely ripe. There was also
an abundance of the common wild raspberries.

From Gros-Cap to the mouth of the river, the water was not more
than three or four feet deep ; the bottom gravel. Farther out
it is deeper, but the amount of water that leaves the lake is
small, as is shown by the moderate rate of the current at the,
entrance of the river, notwithstanding the narrowness of the outlet.
At the Pointe-aux-Pins, where the shores from being over two
miles apart suddenly approach to within half a mile of each other,
we did not perceive any acceleration of the current. The fact is
the channel has only this width all the way down to the Sault ; the
rest being very shallow. The banks are low, so that a very slight
elevation of the surface of the lake would give an outlet of five or
ten miles in width down to the Sault, and expanding below.

Arriving at the head of the portage, we found some of our friends
awaiting us. Both the boats had got in just before us, and they
had hastened to get on their civilized costume and run back to meet
us. Singularly enough, the " Dancing Feather " had arrived that
morning, about two hours before us ! So here we were all on the
day appointed for meeting, although we had paddled four hundred
miles, and they twice as far since we parted.

122 LAKE SUPERIOR.

We had arranged to shoot the Rapids, instead of landing above.
The men did not seem to think it much of an exploit, and made no
change in the stowage of the canoe. The oars were taken in ; the
steersman and bowman furnished with paddles instead. We glided
quietly down, the paddles just touching occasionally, with a few rapid
and vigorous strokes at certain points.

The water is so little broken that we seemed not to be moving
very fast, and it was startling on looking down over the side to see
the bowlders on the bottom twitched by so quickly that it was impos-
sible to see their forms. It was like looking down from a railway
car upon the sleepers. Whether from bravado on the part of our
men, or from the necessity of the case, we several times passed with-
in a foot or less of rocks apparently just under the surface. We
were not more than three or four minutes going down, though the
distance is nearly three quarters of a mile.

CHAPTER IV.

FROM THE SAULT HOMEWARD.

LAKE SUPERIOR is to be figured to the mind as a vast basin with a
high rocky rim, scooped out of the plateau extending from the Alle-
ghanies to the Mississippi valley, a little to the south of the height of
land. Its dimensions, according to Capt. Bayfield, are three hundred
and sixty miles in length, one hundred and forty in breadth, and fifteen
hundred in circumference. The mountainous rim is almost unbroken ;
its height varies from the average of about three or four hundred
feet, to twelve or thirteen hundred ; the slopes are gradual towards
the north, and abrupt on the opposite side, so that on the north shore
the cliffs rise steeply from the water, whilst on the south it is said
the ascent is more gentle ; the abrupt faces being inland.

This difference of formation, joined to the prevalence of northerly
winds, has given very different aspects to the two shores ; the southern
showing broad sand-beaches and remarkable hills of sand, whereas
on the north shore the beaches are of large angular stones, and sand
is hardly to be seen except at the mouths of the rivers. The rivers
of the southern shore are often silted up, and almost invariably, it is
said, barred across by sand-spits, so that they run sometimes for
miles parallel to the lake, and separated from it only by narrow strips
of sand projecting from the west.

The continuity of this rini occasions a great similarity among the
little rivers on the north and east shores, and no doubt elsewhere.
They all come in with rapids and little falls near the lake, and more
considerable ones farther back. These streams are said often to have
in their short course a descent of five or six hundred feet.

124 LAKE SUPERIOR.

This huge basin is filled with clear, icy water, of a greenish cast,
the average temperature about 40 ° Fahrenheit. * Its surface is
six hundred and twenty-seven feet above the level of the sea ; its
depth, so far as actual soundings go, is a hundred and thirty-two
fathoms, that is, one hundred and sixty-five feet below the sea level ;
but Bayfield conjectures it may be over two hundred fathoms in some
places. f

In. geographical position the lake would naturally seem to lie
within the zone of civilization. But on the north shore we find we
have already got into the Northern Regions. The trees and shrubs
are the same as are found on Hudson's Bay ; spruces, birches and
poplars ; the Vaccinia and Labrador tea. Still more characteristic
are the deep beds of moss and lichen, and the alternation of the dense
growth along the water, with the dry, barren, Jichenous plains of the
interior. Here we are already in the Fur Countries ; the land of
voyageurs and trappers ; not from any accident, but from the char-
acter of the soil and climate. Unless the mines should attract and
support a population, one sees not how this region should ever be
inhabited.

This stern and northern character is shown in nothing more clearly
than in the scarcity of animals. The woods are silent, and as if de-
serted ; one may walk for hours without hearing an animal sound,
and when he does, it is of a wild and lonely character ; the cry of a
loon, or the Canada jay, the startling rattle of the arctic woodpecker,
or the sweet, solemn note of the white-throated sparrow. Occasion-
ally you come upon a silent, solitary pigeon sitting upon a dead
bough ; or a little troop of gold-crests and chickadees, with their
cousins of Hudson's Bay, comes drifting through the tree-tops. It
is like being transported to the early ages of the earth, when the
mosses and pines had just begun to cover the primeval rock, and
the animals as yet ventured timidly forth into the new world.

The lake shows in all its features a continental uniqueness and
uniformity, appropriate to the largest body of fresh water on the

* Logan, and Dr. Charles T. Jackson. A recent letter from the, lake, dated July 1,
1840, mentions the temperature of the surface, at eight o'clock, P. M., as 37°.

Society of Quebec, (cited in Bouchette's " British Dominions in North America." I.,

globe. The woods and rocks are everywhere the same, or similar.
The rivers and the islands are counterparts of each other. The very
fishes, although kept there by no material barrier, are yet different
from those of the other lakes. Where differences exist between the
various parts, they are broad and gradual.

Aug. 16£/i, Ylth and ~L8th. - - Principally employed in arranging
and packing specimens. Prof. Agassiz' collection alone occupied
four barrels and twelve boxes, mostly of large size.

In the meantime our party gradually dispersed. Some took the
steamer for Mackinaw ; others were to remain for a few days at the
Sault, whilst another party determined to take the English steamer
u Gore," to Sturgeon Bay, and return home through Upper Canada.

Aug. 19th. — We started at eight o'clock A.M. in the " Gore," a
very well-arranged and comfortable boat. Our first move was to
cross the river, where we took in the (English) Bishop of Toronto,
with his chaplain and another clergyman. We understood they had
been consecrating a church on the English side.

The scenery below the Sault is pleasing, and in many respects like
that we had just left, as if the influence of the "Great Lake extended
beyond its shores. The trees seemed to be of the same species, and
there was the same abundance of wooded islands and islets. The
Professor observed that the scratches on the rocks were not parallel
to the valley, but have a constant north and south direction. The
high land forming the sides of the valley retreats gradually on each
side, leaving a wide expanse of low shores which would be inundated
by a slight elevation of the water. For some distance below the
Sault the river is shallow, and the bottom distinctly visible, showing
ripple-marks in many places which are constantly covered by several
feet of water.

About three o'clock P.M., we reached the Bruce copper-mine, to
the northward of St. Joseph's Island. The long wooden pier to
which we moored was heaped with the most brilliant ore of the kinds
the miners call " horseflesh" and " peacock ore," having every hue
of blue, purple and golden. The first question the agent asked us
when we landed, was, whether we had a medical man with us, for
two of his men had just been injured by a premature explosion. For-
tunately, there were two of the profession in our party, not to count

the Professor, and the poor fellows were immediately attended to.
They were dreadfully burnt and torn about the face, and were moan-
ing with pain, and still more at the thoughts of losing their eyes, and
thus their means of support. The doctors shook their heads at first,
but afterwards, after proper washing, &c., their case looked better.
They were taken on board to be carried to the hospital at Penetan-
guishene, and we had the satisfaction on landing them there of believ-
jng that they would come out with an eye apiece, at the worst.

This mine belongs to the Montreal Company, and the little settle-
ment has a thriving look. The works that we saw were mostly open
trenches, displaying a few feet of top-soil, consisting of unstratified
drift, clay with scratched pebbles and bowlders. The metalliferous
rock, which is sienite and metamorphic talc-schist, with veins of
quartz, is also polished and scratched. The ore consists of various
sulphurets of copper, particularly the yellow. At St. Joseph's, where
we stopped to wood, the Captain, (a very intelligent man, abounding
in information concerning the country,) took us to see a rock which
he considered a great curiosity. It proved to be a large bowlder of
the most beautiful conglomerate, presenting a great variety of bril-
liant colors ; agates, jasper, porphyry, trap, &c., all polished down to
an even surface. Other bowlders of the same kind were lying about
near the beach. The rock in place is Trenton limestone, and full
of the organic remains peculiar to that deposit. We observed great
numbers of bowlders on all the islands we passed in Lake Huron.

There is a little settlement on this end of the island, which the
captain called his, as the land belongs to him. He bought seven
hundred acres, (no doubt of our friend the Major and his co-tenant,)
at the rate of twenty cents an acre, for land said to be fertile, and
certainly supporting a fine growth of hard-wood trees.

In the evening the Professor made the following remarks on occa-
sion of the bowlder :

" This bowlder may be considered as an epitome of all the rocks we have
seen. A complete examination of it would occupy a geologist many months.
This conglomerate is associated with the oldest stratified formations, and must
have been formed in the same epoch with them. Its component parts give
us some insight into its age. It contains no fragment of fossiliferous rock ;
thus the pebbles of which it is composed must have been broken off, rolled

NARRATIVE. 127

by the waves and thereby rounded and smoothed, and afterwards cemented
together, before the appearance of animal life on the earth. On the other
hand it contains trap ; thus trap-dykes must have been thrown up at that
early period. Its other elements are jasper, porphyry, agate, quartz, and
even mica ; all belono-ins: to the ancient rocks which we have seen on Lake

/ O O

Superior. In one of the bowlders the materials are slightly stratified, so
that they had been arranged in layers before they were cemented together.
In all of them the cement is more or less vitrified, showing a strong action
of heat. , This must have been derived from plutonic agencies, so that the
plutonic action on the lake commenced before the introduction of animal life.
The sandstone formations about Gros-Cap and Batcheewauung Bay indicate
in all probability the beaches of the ancient continents from which these frag-
ments were detached, and the outlines of the seas by which they were rolled
and worn. Afterwards they were conglomerated, and then removed hither
by other agencies. This bowlder does not show the marks of having been
transported by the action of water. Its surface is smoothed and grooved in
a uniform manner, without the slightest reference to the different hardness
of its various materials. Had it been worn into its present shape by the
action of water, the harder stones would be left prominent. I have no doubt,
from similarity of its appearance in this respect to the rocks -of the present gla-
ciers of Switzerland, that it has been firmly fixed in a heavy mass of ice and
moved steadily forward in one direction, and thereby ground down."

These remarks being made in the main cabin, in the presence of
the Captain and the other passengers, one of the clergymen after-
wards took the Professor to task for denying that the world and its
inhabitants were all made at once, as if this was a well-understood
thing, and got quite indignant, when he would not admit that the
Bible had so settled it. His tone on this occasion, (for otherwise he
appeared to be a well-bred and educated man,) seemed to indicate a
different position of- the old theologico-geological question here, a
question one would have thought finally disposed of among men of
liberal training.

Aug. 20t7i. — "We stopped this morning at a little settlement on the
Grand Manitoulin, whither the Indians come yearly to receive their
" presents." A few soldiers are stationed here to keep order on
these occasions. It is a significant fact that both here and at Mack-
inaw, the ground-rent paid by the British and United States govern-

ments to the original lords of the soil, goes under the name of a
present, as if dependent on the mere good-will and pleasure of the
tenants.

The Indians had been collected here a week or two before, it was
said, to the number of three or four thousand ; we saw the traces of
their encampment on the beach. In general it is only those living in
the neighborhood that come, since to journey hither from the more
distant villages would cost more than the " present" would come
to.

On one occasion, the Captain saw a general collection of the tribe
from all quarters, as far as the Red River settlement on the one
hand, and Hudson's Bay on the other. There were in all about five
thousand six hundred persons, men, women, and children. As usual
they carried little or no food with them, and such a multitude soon
exhausted the fish and game of the neighborhood. Terrible want
ensued, and as the English authorities for some time refused any
assistance, many were near starvation. Some families, to his knowl-
edge, went three days without food ; others lived on small bits of
maple sugar, which were divided with scrupulous accuracy. At last
the officer in charge ordered some Indian corn and " grease" to be
served out to them. The Captain was standing with the officers when
this order was executed, and understood (though they did not,) the
speech the chief made to his men on the occasion. " When strangers
come to visit ^<s," said he, " we look round for the best we have, to
offer to them. But we must take this, or starve."

If it be said that the strict law of nations is not applicable to deal-
ings with savages, any more than the municipal law to the manage-
ment of children, — at least they should have the benefit of the
principle. If we claim to stand in loco parentis with regard to them,
we should show some parental solicitude for their welfare. But the
poor savages fall between the two stools, and get neither law, equity,
nor loving kindness at our hands. It is difficult to see, for instance,
why the annual stipend should not be paid to the Indians at places
in a measure convenient for them to receive it, say at La Pointe, on
the American side, and Fort William, the Red River settlement, and
the like on the Canadian, instead of practically cheating them out of
it in this way.

NARRATIVE. 129

The settlement consists of a store-house on the beach, and a few
neat whitewashed cottages along the top of the high bank, with their
fronts overrun with vines. A little way back from the bluff was a neat
Gothic church, of wood, not quite finished ; service was held in a
small building beyond. The rock, which is Trenton limestone, and
full of fossils, crops out everywhere in nearly horizontal strata.

Soon after leaving this place we entered the Georgian Bay, so
called, the Captain says, ever since he has known it, though one sees
it named Lake Manitoulin, or Manitoulin Bay, on some maps. He
commanded the first steamboat that plied between Penetanguishene
and the Sault. The trip occupied four or five days ; they crept
along the northern shore, stopping to cut wood where they wanted it,
and lying by at night.

High land was now in sight to the northward ; mountains of about
twelve hundred feet elevation. The water is very deep, but from
the number of islands and rocks, the navigation is dangerous, and it
is necessary to anchor in case of fog. Sometimes no bottom can be
had close to shore, and then they have to make fast to trees. Nor-
thern Lights this evening.

Aug. 21s£. — We arrived at Penetanguishene early in the fore-
noon, and remained there a short time to wood, &c. The wounded
men were carried on mattresses to the Military Hospital. Near the
entrance was a war steamer, moored at one of the wharves. This
vessel, in accordance with treaty, carries but one gun. The village
is situated at the bottom of a deep narrow bay ; the shores on the
right going in are low and covered with wood ; on the left, the ground
rising and cleared for cultivation. The sight of fences and farm-
houses here was more home-like than anything we had seen for some
time. The place seems to be a thriving one, and it is thought the
road from the lake to Toronto will ultimately commence here. The
upper part of the bay, however, near the town, seems to be too shal-
low to favor navigation. Judging from a slip of paper offering a
reward for certain Indian curiosities, which was stuck up in one of
the shops, there would seem to be some one here who has the good
sense to look after the remains of the aboriginal inhabitants.

The distance to Sturgeon Bay, where we were to leave the
boat, is not great, but from the stop at Penetanguishene, and the

crookedness of the course, it was two o'clock before we got there.
On our arrival, we found some confusion. So large a number of pas-
sengers had not been expected, for the travel on this route is very
inconsiderable ; the boats being maintained principally by their con-
tracts with the Post-office.

The place consists of a small gap cut in the forest, large enough
for a single rather neat frame-house and out-buildings. From it a

o o

dark lane, cut straight into the woods, was the road we were to take,
' a highway in its most primitive stages, as we found when, after some
delay, we got off in three large open wagons, into which we were
stowed with our luggage, as close as cattle on the way to market.

We found on our first landing a marked change both in the Fauna
and the Flora. The woods are like those of Western New York in
the size and species of the trees. We saw again red and sugar
maples, red and white oaks, hop-hornbeam, beech, ash, basswood,
sumach, &c., and among the birds we recognized the red-headed
woodpecker and blue jay.

The road for the first thirteen miles was as bad as could be found,
at this season of the year, on the continent, and we had to keep all
the way at a walk. In the spring I should think it could be hardly
passable by heavy wagons. For this distance, we saw no signs of
habitation except a few scattered ruinous log-cabins, built by Indians,
who had been encouraged to settle here, but who had long since
deserted them.

After that we began to meet clearings, growing more and more
numerous as we approached Coldwater. At one of these we suc-
ceeded in getting some excellent bread and milk, after convincing
the mistress, a canny North-country woman, of our solvency.

Coldwater is a decayed looking village, run to pigs, snake-fences
and wide straggling streets. According to the Bishop, who as cura-
tor of things spiritual in this district ought to know, the inhabitants
have a very general antipathy to the article after which the place is
called, whence perhaps their unprosperous condition. Beyond Cold-
water we got on to higher land, where the road is better, and we
mended our pace, but it was dark before we reached Orilla Landing
on Lake Simcoe.

Finding the steamer here, we went on board to engage our pas-

sage, and were so much pleased with the appearance of things, that
we resolved to pass the night there rather than at the tavern.

Aug. 22c?. — The Lake Simcoe District as it is called, is, it seems,
already noted for its fertility, particularly as a wheat country,
although a large part of it is still uncleared. Judging from the
growth of timber, the portion on Lake Huron must be at least equal
to any of it. Patriotic and enthusiastic Sir Francis Head pronounces
it the best land in North America ; but without going so far as this,
it may probably approach that of the north-western part of New
York. The immediate border of the lake is, as I understand, less
fertile ; for this reason, probably, the forest is but sparingly inter-
rupted by clearings. The lake is too large, and its shores too low
and flat, to be beautiful ; but it is saved from monotony by numbers
of wooded islets. Its height above Lake Huron is 152 feet.

About noon we came to a river-like strait, with wide sedgy shores,
which are said to afford capital duck and snipe shooting. Even at
this time there were a few ducks. Arriving at Holland Landing, we
found the same difficulty about conveyances to St. Albans, and most
of us walked thither, three miles, sending our luggage by a wagon.

The name St. Albans has an old-world sound, and the place
itself had an old-world look, for, though a raw kind of village
enough, yet there were, I think, five very nice saddlers' shops, a
tailor " from London," with a very neat establishment, and other
signs of a somewhat aristocratic element in the population, probably
due to the number of retired British officers who have farms in the
neighborhood, and still keep up the equestrian habits, and something
of the attention to dress, that distinguish their nation and class.
Even the public houses were not " hotels," but " inns."

After dinner we packed into two stages, which, however, would not
contain our effects, so they had to follow after, whereby we were
much delayed, and I lost my best Mackinaw blanket, faithful com-
panion in the 'wilderness, purloined from the top of my trunk.

The road beyond St. Albans is everywhere excellently well built,
but the first part of it had been but recently macadamized, which
reduced our pace to a walk. The country all the way is very pretty,
neat villages and farm-houses increasing in number as we approached

132 LAKE SUPERIOR.

Toronto, and all filled with troops of the rosiest children, and sur-
rounded by fine orchards and corn-fields. The hay seemed in many
instances at least to be stacked, in the English fashion, instead of
being stored in barns. Vines and ornamental trees were beginning
to be cultivated about the houses, though the prevalence of balsam-
firs showed that they had not got far in this direction. The houses
are sometimes of a very agreeable cream-colored brick, made in the
neighborhood ; most frequently, however, rough-cast, upon lath, with
a mixture of plaster, lime and coarse sand, which is said to stand
perfectly well. The forest trees are principally white pines, some
very fine specimens of which we saw along the road. These afford
employment to a number of steam saw-mills, and large quantities of
lumber are exported from Toronto.

The government lands here, I was told, are divided off into strips
two lots deep, by parallel roads, and these being joined at certain
intervals by cross lanes, the division of farms is rendered very sym-
metrical. Probably, however, this necessitates the buying of an
entire lot, or none at all ; at all events, we understood that for some
reason or other the transfer of real estate is much hampered by the
regulations of the Land Office.

We arrived at Toronto by gas-light, and found nobody awake but
a train of geese who were solemnly waddling across the street.
We went to the Wellington Hotel, a very dirty and uncomfortable
place.

Aug. 23d. — Our baggage did not arrive until this morning, fif-
teen minutes before the boat for Queenston started. My compan-
ions contrived to get on board, but I was left to pass the day in
Toronto. My first move was to transport my effects to the North
American House, somewhat better than the other, but very far from
good.

Toronto is very regularly built, of the cream-colored brick above-
noticed, in some cases stuccoed. The streets are wide, and both
carriageway and sidewalk made of plank, laid transversely. Many
of the houses in the suburbs have extensive gardens and ornamental
grounds, but in the city itself there are no buildings of much preten-
sion to beauty, and very few attractive shops.

NARRATIVE. 133

Aug. 24th. — Early this morning I took to the boat for Queens-
ton, and thence by a very wretched railway reached Niagara to
dinner.

Aug. 25th. — We went by the railroad to Lockport, to pay a visit
to Colonel Jewett, the most warm-hearted of collectors of fossils. He
showed us his collection as far as it was accessible, gave the Pro-
fessor several specimens, and showed us where to pick up more for
ourselves. At the quarry of hydraulic limestone we saw an interest-
ing document for the geology of the drift-period. The soft rock was
abundantly furrowed, from a direction a little west of north. One of
these furrows gradually deepened, until it was interrupted by a suc-
cession of horseshoe shaped hollows, sloping from the north, and deep
and abrupt towards the south, showing that the furrowing mass was
moving from north to south, and from some interruption had chipped
out these bits.

From Lockport we drove to the line of the railroad, and returned
home by the same way as we came.

THE NORTHERN VEGETATION COMPARED WITH THAT OP
THE JURA AND THE ALPS.

IT is now universally known that living beings, animals and plants,
are not scattered at random over the surface of the whole globe.
Their distribution, on the contrary, is regulated by particular laws
which give each country a peculiar aspect. We call climate the
physical conditions which seem to regulate this distribution, however
diversified the causes thus acting may be. The distribution of heat
all the year round ; the mode of succession of temperature, either
by sudden or gradual changes ; the degree of moisture of the atmos-
phere ; the pressure of the air ; the amount of light ; the electric
condition of the atmosphere ; all these and perhaps some other agents
continually influence the growth of plants and the development of
animals. The nature of the soil is no less powerful in its influence
upon organized beings, though here also very different agents are
considered under one head ; as the chemical properties of the ground
are evidently as efficient as the physical.

Let us for a moment examine these circumstances. Temperature
seems to be the all-ruling power. With the returning smile of
spring, vegetation bursts out with new vigor, and dies again as the
cold of winter brings back its annihilating rigors. Under the hot
sun of the tropics the beauty and variety of vegetation exceed all
that is known in more temperate regions, whilst as we approach the

polar plains we see it grow gradually less diversified and more dwarf-
10

ish, thus exhibiting all over the globe a close connection between
the modifications of temperature from the equator to the poles, and
the geographical distribution of vegetable and animal life. The
more powerful influence of temperature upon vegetation does not,
however, preclude the influence of other agents ; even the manner
in which the same amount of heat is distributed over the earth in a
given time, will produce differences. It is well known, that coun-
tries in which the summers are short but very warm, and the winters
very long and cold, have a vegetation totally different from those
where the seasons are more equable and succeed each other by
gradual changes, although the mean annual temperature of both be
the same. Next in importance we may perhaps consider the degree
of moisture of the atmosphere, which differs widely in different re-
gions ; the damp valleys of the Mississippi, for instance, present the
most striking contrast with the rolling country farther west. Again,
the swamps and the sandy plains, the rocky hills and the loamy soils,
the snow-clad barrens and the frozen gravel of the North, even under
circumstances otherwise most similar, afford the greatest diversity of
vegetation. There is still another way in which moisture may act
in a particular manner ; as vegetation is not influenced simply by
the annual amount of moisture, but also by the quantity of water
that falls at one time, and the periods at which it falls. A low tem-
perature in a moist climate will indeed produce some remarkable
peculiarities ; for instance where early winters cause an extensive
sheet of snow to be accumulated over the ground, and to protect
vegetation from the destroying influence of frost ; as is the case in
the Alps, where the most delicate flowers prosper admirably under
their white blankets, and show themselves in full development as soon
as the snow melts away, late in the spring, when the warm season is
already fairly set in. Light, again, independently of heat, will also
show its influence ; shaded places are favorable to plants which would
be killed under the more direct influence of the rays of light.

Atmospheric pressure would at first seem to have only a very sub-
ordinate influence upon vegetation. But comparing Alpine vegetation
with that of higher latitudes, which from their situation must have
climates otherwise very similar, we shall be led to the conclusion that
atmospheric pressure has its share in bringing about the diversity o f

THE NORTHERN VEGETATION COMPARED, ETC. 139

plants ; for though analogous, the flora of the high North is by no
means identical with that of the most elevated Alpine ridges, over
which vegetation continues to extend. The influence of atmospheric
pressure seems to me particularly evinced in the great, I may say
the prevailing numher of Alpine species endowed with a volatile fra-
grance which adds so much to the sweet and soothing influence of
mountain rambles ; whilst the northern species, however similar to
those of the Alps, partake more or less of the dullness of the heavy
sky under which they flourish.*

Whatever may be the intensity of other causes, and even when
they are most uniform, the chemical nature of the soil acts perhaps
as powerfully as the physical conditions under which the plant may
grow. To be fully impressed with the important influence of the soil
we need only be familiar with the differences noticed in the growth
of wheat or other grains in different soils, or with the different aspect
of pastures on rich or poor grounds, and to trace the same modifica-
tions through any small tract of land with the view to understand
similar changes over wider countries.!

* It would be a mistake to ascribe to reduced atmospheric pressure the peculiar aspect
of most plants in the higher Alps, as they are undoubtedly more influenced by the
temperature, and especially by the pressure of the snow of those high regions. These
plants are commonly covered with a thick and close down, which reminds us of the soft
fur of the northern animals ; they creep for the most part attached to the compact and
tenacious soil among the clefts of rocks, where their roots can penetrate and where they
find shelter. Several of them have fleshy and succulent leaves, filled with liquid,
derived rather from the atmosphere, than from the stony and dried soil upon which we
generally find them. These phenomena of Alpine vegetation occur successively at a
less considerable elevation the more we advance northwards, and show themselves on
the plains towards the polar regions, where the temperature agrees with that of the
high Alpine summits. The fact that many plants of the highest summits live very well
at the foot of the glaciers which descend into the lower valleys, would seem to show
that atmospheric pressure has only a limited influence upon Alpine plants ; but the mo-
ment we have satisfied ourselves that the most fragrant of these species never prosper
below, we must admit that the relation between fragrance and atmospheric pressure to
which I have alluded above, is well sustained. The Alpine plants are, it is well known,
very difficult to cultivate ; Mr. Vaucher, at Fleurier, assisted by Mr. Lesquereux has
however succeeded in bringing together a magnificent and numerous collection of spe-
cies of the high Alps. In order to preserve them, they took care to harden and press
the soil, or to introduce small blocks of limestone into it, and to cover them with snow
in the spring, but especially to press the roots very often into the ground in the spring,
as they are otherwise pushed out after every frost, and perish in a single day if care be
not taken to put them again without delay into the ground.

•(• The chemical elements of the soil seem, however, to have less influence upon the
geographical distribution of the large vegetables or pha?nogames, than upon the cryp-

140 LAKE SUPERIOR.

To satisfy ourselves of the powerful influence of electricity upon
vegetation, we need only remember the increased rapidity with which
plants come forth, during spring, after thunder storms.

Many other causes still more intimately connected with the aspect
of our globe have also a great influence upon the distribution of the
animals and plants which live on its surface. The form of continents,
the bearing of their shores, the direction and height of mountains,
the mean level of great plains, the amount of water circumscribed
by land and forming inland lakes or seas, each shows a marked influ-
ence upon the general features of vegetation. Small low islands,
scattered in clusters, are covered with a vegetation entirely different
from that of extensive plains, under the same latitudes. The bearing
of the shores again, modifying the currents of the sea, will also react
upon vegetation. Mountain chains will be influential not only from
the height of their slopes and summits, but also from their action

togames. The attempts made to group the former according to the nature of the soil
upon which they grow, have afforded no satisfactory results. It is otherwise when we
consider the hydrodynamic capacity of the soil, that is to say, the property which it
has to retain the water for a longer or shorter time. Tracing our investigations in
this direction we arrive, on the contrary, at very important conclusions. A sandy
desert and a peat-bog for instance, as the two extremes, have quite peculiar florae,
which stand completely isolated from the vegetation of soils whose essential component
material is humus. This fact is in perfect accordance with recent discoveries in vege-
table physiology, which seem to prove that plants extract nothing from the soil except
water, or nourishment in a liquid state, and that their other components, the carbon
in particular, are furnished them from the atmosphere.

As we descend the scale, and arrive at the cryptogames, the chemical influence
of the soil is gradually more and more felt in the distribution of the genera, and
even of the species. The mosses even may be readily grouped according to the locali-
ties where they live. The Orthotrichoe occur almost exclusively upon the bark of trees,
and upon granite and limestone ; the Phascaceae inhabit clayey soils, with the Gym-
nostomeac, Pottiea?, Funarieoe and some Weissiae. The Sphagneee occur only in peat-
bogs, or in waters charged with ulmic acid ; the Splachneae generally upon animal sub-
stances in decomposition; the Grimmieoe upon granitic rocks ; whilst the greatest num-
ber of the Hypnums and Dicranums cover large surfaces of rotten vegetables. And
if we take into consideration the modifications which temperature introduces in the
habitation of some mosses, we are enabled to account even for the cosmopolitism of
some species which, like the Bryums, would seem to be less influenced than others by
the nature of the soil upon which they grow.

The examination of the lichens which attach themselves commonly to the surface of
woods and rocks leads to conclusions still more striking. Some species live exclusively
upon limestone ; others upon mica schist ; others upon various kinds of granite ; and
others finally upon certain species of trees or other vegetables. The analysis of the
substances upon which lichens live, has, if not completely explained, at least led to
the understanding of the causes of the remarkable distribution of these plants.

upon the prevailing winds. It is obvious, for instance, that a moun-
tain chain like the Alps, running from east to west, and thus forming
a barrier between the colder region northwards, and the warmer
southwards, will have a tendency to lower the temperature of the
northern plains, and to increase that of the southern, below or above
the mean which such localities would otherwise present ; while the
influence of a chain running north and south, like the Rocky Moun-
tains and the Andes, will be quite the reverse, and tend to increase
the natural differences between the eastern and western shores of
the continent, and, laying open the north to southern influences and
the south to thosa of the north, render its climate excessive, i. e.,
its summer warmer and its winter colder.

Again, the equalizing influence of a large sheet of water, the tem-
perature of which is less liable to sudden changes than the atmos-
pheric air, is very apparent in the uniformity of coast vegetation
over extensive tracts, provided the soil be of the same nature, and
also in the slower transition from one season into the other along the
shores ; the coasts having less extreme temperatures than the main
land. The absolute degree of temperature of the water acts with
equal power ; as the aquatic plants of the tropical regions, for in-
stance those of Guyana, differ as widely from those of Lake Supe-
rior, as the palms differ from the pine forests. *

* One of the most prominent causes of the dispersion, not to say of the distribution
of plants, is certainly the direction and the swiftness of water-courses. On one hand
the rivers bring down from the summits or the elevated parts of the country a large
number of plants and seeds, which are stopped and take root farther below, on their
banks ; on the other, they spread in their neighborhood a greater or less amount
of moisture. This is, I think, the best cause to assign to the uniformity of vegeta-
tion over large plains, traversed by rivers, or to that of the sea-shores, or especiallj
to that of the low islands and peninsulas of little extent. We must also admit, how-
ever, that there are along the course of rivers a great variety of stations, which we
may find nowhere else, valleys, abrupt rocks, shaded places, constantly or alternately
lighted by the sun according to their bearing ; and that in this manner secondary agents
may have their influence in varying'greatly the aspect of vegetation.

It is also a curious but positive fact, that high mountain chains have a direct influ-
ence upon the dissemination of the species over the neighboring secondary chains,
even at a considerable distance. This fact is plainly shown in the Jura for instance,
where from the summits of the Dole to those of the Chasseral we observe a true Alpine
vegetation, less and less abundant the more we recede from the Alps in one or another
direction. At an equal elevation the summits of the northern Jura lose every trace of
Alpine plants which we find so abundantly upon its southern summits, especially upon
the ridges near the Alps, as the Dole, the Mount Tendre, for instance. The same takes

142 LAKE SUPERIOR.

But however active these physical agents may be, it would be
very unphilosophical to consider them as the source or origin of the
beings upon which they show so extensive an influence. Mistak-
ing the circumstantial relation under which they appear, for a causal
connection, has done great mischief in natural science, and led
many to believe they understood the process of creation, because
they could account for some of the phenomena under observation.
But however powerful may be the degree of the heat ; be the air
ever so dry, or ever so moist ; the light ever so moderate, or ever
so bright ; alternating ever so suddenly with darkness, or passing
gradually from one condition to the other ; these agents have
never been observed to produce anything new, or to call into
existence anything that did not exist before. Whether acting
isolated or jointly, they have never been known even to modify to
any great extent the living beings already existing, unless under the
guidance and influence of man, as we observe among domesticated
animals and cultivated plants. This latter fact shows indeed that
the influence of the mind over raaterial phenomena is far greater
than that of physical forces, and thus refers our thoughts again and
again to a Supreme Intelligence for a cause of all these phenomena,
rather than to so-called natural agents.

Coming back from these general views to our special subject, it
will be observed that North America must, a priori, be expected
to have, in some parts, a very diversified vegetation, owing to the
peculiarities of its natural geographical districts, and in others, viz.,
over its extensive tracts of uniform plains, a vegetation as uniform
as anywhere in the world.

The physical agents whose influence upon organized beings we
have just examined, show a regular progression in their action, which
agrees most remarkably with the degrees of latitude on one side,
and the elevation above the level of the sea on the other. Hence
the difference in the vegetation as we proceed from the tropical
regions towards the poles, or as we ascend from the level of the

place westwards. The list of Alpine species found upon the Dole amounts to one
hundred, whilst upon the 'Weissenstein, where even the Anemones have disappeared,
we find no other representative of that beautiful flora of the snow regions, than the
s ole Erinus Alpinus.

THE NORTHERN VEGETATION COMPARED, ETC. 143

sea to any height along the slopes of a mountain. In both these
directions there is a striking agreement in the order of succession of
the phenomena, so much so, that the natural products of any given
latitude may be properly compared with those occurring at a given
height above the level of the sea ; for instance, the vegetation of
regions near the polar circles, and that of high mountains near the
limits of perpetual snow under any latitude. The height of this limit,
however, varies of course with the latitude. In Lapland, at 67° north
latitude, it is three thousand five hundred feet above the level of the
sea ; in Norway at lat. 60° it is five thousand feet ; in the Alps at
lat. 46° about eight thousand five hundred ; in the Himalaya at lat.
30° over twelve thousand ; in Mexico at lat. 19° it is fifteen thou-
sand ; and at Quito under the equator, not less than sixteen thousand.
At these elevations, in their different respective latitudes, without
taking the undulations of the isothermal lines into consideration,
vegetation shows a most uniform character, so that it may be said
that there is a corresponding similarity of climate and vegetation be-
tween the successive degrees of latitude and the successive heights
above the sea. As a striking example I may mention the fact of the
occurrence of identical plants in Lapland in lat. 67° at a height of
about three thousand feet and less above the level of the sea, and
upon the summit of Mount Washington in latitude 44° at a height
of not less than six thousand feet, while below this limit, in the
wooded valleys of the White Mountains, there is not one species
which occurs also about North Cape.

There is nevertheless one circumstance which shows that climatic
influences alone, however extensive, taking for instance into account
all the above-mentioned agents together, will not fully account for the
geographical distribution of organized beings, as their various limits
do not agree precisely with the outlines indicating the intensity of
physical agents upon the surface of the earth. A few examples
may serve to illustrate this remark. The limit of forest vegetation
round the Arctic Circle, does not coincide with the astronomical
limits of the Arctic zone ; nor does it agree fully with the isother-
mal line of 32° of Fahrenheit ; nor is the limit of vegetation in
height always strictly in accordance with the temperature, as the Ce-
rastium latifolium and Ranunculus glacialis, for instance, occur in the

144 LAKE SUPERIOR.

Alps as high as ten, and even eleven thousand feet above the level of the
sea. Again, eastern and western countries within the same continent,
or compared from one continent to the other, show such differences
under similar climatic circumstances, that we at once feel that some-
thing is wanting in our illustrations, when we refer the distribution of
animals and plants solely to the agency of climate. But the most
striking evidence that climate neither accounts for the resemblance
nor the difference of animals and plants in different countries, may
be derived from the fact that the development of the animal and
vegetable kingdoms differs widely under the same latitudes in the
northern and in the southern hemispheres, and that there are entire
families of plants and animals exclusively circumscribed within certain
parts of the world ; such are, for instance, the magnolia and cactus
in America, the kangaroos in New Holland, the elephants and rhi-
noceros in Asia and Africa, &c. &c.

From these facts we may indeed conclude that there are other
influences acting in the distribution of animals and plants besides cli-
mate ; or perhaps we may better put the proposition in this form :
that however intimately connected with climate, however apparent-*
ly dependent upon it, vegetation is, in truth, independent of those
influences, at least so far as the causal connection is concerned, and
merely adapted to them. This position would at once imply the
existence of a power regulating these general phenomena in such a
manner as to make them agree in their mutual connection ; that is
to say, we are thus led to consider nature as the work of an intelligent
Creator, providing for its preservation under the combined influences
of various agents equally his work, which contribute to their more
diversified combinations.

The geographical distribution of organized beings displays more
fully the direct intervention of a Supreme Intelligence in the plan
of the Creation, than any other adaptation in the physical world.
Generally the evidence of such an intervention is derived from the
benefits, material, intellectual, and moral, which man derives from
nature around him, and from the mental conviction which conscious-
ness imparts to him, that there could be no such wonderful order in the
Creation, without an omnipotent Ordainer of the whole. This evidence,
However plain to the Christian, will never be satisfactory to the man

THE NORTHERN VEGETATION COMPARED, ETC. 145

of science, in that form. In these studies evidence must rest upon
direct observation and induction, just as fully as mathematics claims
the right to settle all questions about measurable things. There
will be no scientific evidence of God's working in nature until na-
turalists have shown that the whole Creation is the expression of a
thought, and not the product of physical agents. Now what stronger
evidence of thoughtful adaptation can there be, than the various
combinations of similar, though specifically different assemblages of
animals and plants repeated all over the world, under the most
uniform and the most diversified circumstances ? When we meet
with pine trees, so remarkable for their peculiarities, both morpholo-
gical and anatomical, combined with beeches, birches, oaks, maples,
&c., as well in North America as in Europe and Northern Asia,
under most similar circumstances ; when we find again representa-
tives of the same family with totally different features, mingling so
to say under low latitudes with palm trees and all the luxuriant
vegetation of the tropics ; when we truly behold such scenes and
have penetrated their full meaning as naturalists, then we are placed
in a position similar to that of the antiquarian who visits ancient
monuments. He recognizes at once the workings of intelligence
in the remains of an ancient civilization ; he may fail to ascertain
their age correctly, he may remain doubtful as to the order in
which they were successively constructed, but the character of the
whole tells him that they are works of art, and that men, like him-
self, originated these relics of by-gone ages. So shall the intel-
ligent naturalist read at once in the pictures which nature presents
to him, the works of a higher Intelligence ; he shall recognize in the
minute perforated cells of the Coniferoe, which differ so wonderfully
from those of other plants, the hieroglyphics of a peculiar age ; in
their needle-like leaves, the escutcheon of a peculiar dynasty ; in their
repeated appearance under most diversified circumstances, a thought-
ful and thought-eliciting adaptation. He beholds indeed the works
of a being thinking like himself, but he feels at the same time that
he stands as much below the Supreme Intelligence in wisdom, power
and goodness, as the works of art are inferior to the wonders of
nature. Let naturalists look at the world under such impressions

146 LAKE SUPERIOR.

and evidence will pour in upon us that all creatures are expressions
of the thoughts of Him whom we know, love and adore unseen.

After these general remarks let us consider more closely the
vegetation of the temperate and of the colder parts of North Ameri-
ca, and compare it with that of the elevated regions forming in
Central Europe the ridge which separates the nations of German
tongue from the Roman. In these notes I shall, however, limit my-
self mostly to trees and forest vegetation, as this is the characteristic
vegetation of those tracts of land, and only introduce now and then
occasional remarks upon the other plants. It is indeed a peculiarity
of the northern temperate regions all over the world, to be wooded,
and to afford room for an extensive development of other plants
only in those places where permanent accumulations of water ex-
clude forests, where a rocky soil does not afford them a genial
ground, or where artificial culture has destroyed them, introducing
in their place agricultural products.

A few families, however, constitute the whole arborescent vegeta-
tion of temperate regions, and the uniformity of the forests all over
that zone in the Old and New World is quite remarkable. In the
first rank we find the Amentaceae and Coniferse,with their various sub-
families and tribes ; next to them maples, walnut, ashes, linden, wild
cherries, &c., &c. In the special distribution of each of these fam-
ilies, we observe, however, some peculiarities which will equally claim
our attention.

There is, for instance, a striking contrast within these limits, between
the vegetation of Coniferae, which are evergreen, and that of Amen-
taceae, Juglandeae, Fraxineae, Acerinae, Tiliaceae, &c., which lose their
foliage in the fall. Again taken as a natural assemblage, the plants
which constitute the northernmost forests are farther remarkable for
covering extensive tracts of land with one and the same species, to
the exclusion of others. Or else a few species are combined together
in various ways, the Coniferas generally excluding the trees with
deciduous leaves, or occurring together but rarely, and vice vers&.

In the warmer parts of the temperate regions, the diversity of
forest trees with deciduous leaves is greater than farther north,
where Coniferae appear almost exclusively. Another difference is ob-
served in the more continuous distribution of northern forests, while

THE NORTHERN VEGETATION COMPARED, ETC. 147

in the warmer climates of the temperate zone they alternate more
frequently with shrubs or grazing grounds, with smaller plants grow-
ing among them. Whatever may be the peculiarities which we
observe in the details of this arrangement, there is, nevertheless, a
remarkable coincidence between the vegetation of the plains from
the middle latitudes northwards, and the vegetation of mountainous
districts, especially in the Alps, as we ascend from the plains towards
their snowy summits ; the same variety of Amentaceae, Fraxineee,
Juglandeae, Acerinae, Pomacese, interspersed with corresponding
shrubs, occur in the lower regions, while in the higher the Coniferse
come in more extensively, to the almost entire exclusion of the
others.

The correspondence between this ascending forest vegetation, and
the distribution of trees over the whole extent of the temperate
zone, is so great, that it may be considered as a most positive and
universal law. The Juglandeae and various forms of Amentaceae,
especially those which produce eatable fruit, as the chestnuts, occur
in the lower latitudes under the influence of a more genial climate,
and disappear entirely below the parallels where agriculture ceases.
So also we find them in the lower regions of mountainous countries.
Farther north we have a variety of poplars, oaks, willows, maples,
ashes, etc., interspread with pines, which begin to form more
continuous forests, till they make room northwards for the almost
uniform pine and birch forest, which covers in unbroken continuity
the northern countries as far as tree vegetation extends ; and again
in a similar succession we observe Amentaceae, Acerinae, &c., &c.,in
ascending higher and higher on the slopes of mountains, the conifer-
ous trees gaining gradually the ascendency over those with deciduous
leaves, until these disappear below the limit of perpetual snow. A
more detailed comparison of this resemblance between northern and
Alpine vegetation, will show that they agree in almost every respect,
and that there are corresponding species under similar circumstances
in different parts of the Old and New Worlds, following each other
in the same succession from south to north, or from the plains to the
mountain summits, modified only by those influences which constitute
the contrasting peculiarities of the eastern and western shores of
America, Europe and Asia ; but in the main agreeing most extensively

148 LAKE SUPERIOR.

over the whole range of forest vegetation throughout both continents.
The tabular view of these plants which is given below, will at once
show the correspondence and divergence.

From these facts it might be inferred that the aspect of wooded
lands, whether mountainous or level, would be very similar ; that
in the northern regions, it compares in every respect with that of
high mountain chains. Such an impression is almost universally
prevalent among those who are conversant with these laws of the
geographical distribution of plants, without having had an opportuni-
ty actually to compare such countries. It having been my good
fortune, after having been for years familiar with the vegetation of
the Alps, to visit the northern regions of this continent within the
limits of the temperate zone, I was at once struck with the great
difference in the general aspect of their vegetation. Indeed, the
picturesque impression is an entirely different one, and nevertheless
the above-mentioned laws are correct ; but the fact is that the
changes of mean annual temperature in this country take place at
the rate of about 1° of Fahrenheit for every degree of latitude, or
for every sixty miles ; or in other words, as we travel north or south,
we reach successively every sixty miles, localities the mean annual
temperature of which is 1° Fahrenheit lower or higher ; while in
the Alps we meet, in ascending or descending, the same change of
1° Fahrenheit in mean annual temperature, for every three hundred
feet of vertical height ; so that we pass within the narrow limits of
between six to seven thousand feet, from the vine-clad shores of the
lakes of Northern Italy and Switzerland, to the icy fields of snow-
mountains, whose summits are never adorned by vegetation ; a
journey which can easily be performed in a single day. Whilst on the
other hand from the 40th degree of northern latitude, 'where the mean
annual temperature is nearly the same as that of the foot of the Alps,
we find towards the northern pole a diminution of one degree of tem-
perature for every degree of latitude, or for every sixty odd miles ; so
that we should travel over twenty degrees of latitude, or more than
twelve hundred miles from south to north, for instance, from Boston
to Hudson's Bay, before passing over the same range of climatic
changes as we do in one day in the Alps ; thus causing a narrow ver-
tical stripe of Alpine flora to correspond to a broad zone of northern

THE NORTHERN VEGETATION COMPARED, ETC. 149

vegetation stretching over a widely-expanded horizon. So that not-
withstanding the correspondence of species, we have in the first case,
in the Alps, a rapid succession of highly-diversified vegetation, whilst
in the other case, in northern latitudes, we have a monotonous uni-
formity over extensive tracts of land, although the elements of the
picture are the same. But it is a picture seen in a different perspec-
tive : in one case we have a simple vertical profile, which in the
other case is drawn out into disproportionate horizontal dimensions ;
like the far-reaching shade of a steeple cast under the light of the
setting sun, which may change all proportions, and destroy all resem-
blance between the shade and the object itself, simply because it is
so much elongated. Fantastic images presented at various distances
before a light falling at various angles, may prepare us to understand
these different aspects of the landscape, be it a wooded plain
along a gentle slope, or a forest along a more abrupt mountain chain.

There is another feature in the geographical distribution of organ-
ized beings which deserves to be particularly noticed, and which con-
tributes to increase the diversity of aspect of vegetation in any given
part of the world. There are in all continents remarkable differ-
ences between the vegetation of the shores of a continent, east
and west, within the same latitude or the same isothermal line. The
forests of the Atlantic and Pacific coasts of temperate America
are not altogether composed of the same plants ; we remark that in
the East there will be a tendency in the different families to develop
in different proportions, and perhaps with the addition or disappear-
ance of one or two peculiar types ; for instance, the walnut family
contains several more representatives on the eastern side of the con-
tinent than on the western, and they prosper here in latitudes where
in Europe there is only one introduced species of that family growing
wild. Again, we find Liquidambar on the American side of the
Atlantic, which has no representative either on the Pacific coast,
or in Europe. This comparison might be traced farther, and we
should see the same correlation even among the shrubs.

But these indications will be sufficient for my object, which is to
show that, although there is an intimate correlation between climate
and vegetation, the temperature and other influences which consti-
tute climate do not reveal the whole amount of causes which produce

150 LAKE SUPERIOR.

these differences, as they are repeated under the same isothermal lines,
between the eastern and western shores of the Old World in the same
order as along the eastern and western shores of North America ;
so much so that the northern Chinese and Japanese vegetation coin-
cides very closely with that of the Atlantic States, whilst that of the
Pacific coasts of America and that of Europe agree more extensively.

This picture would be incomplete did I not institute a farther com-
parison between the present vegetation of those regions and the fos-
sil plants of modern geological epochs. If we compare, namely, the
tertiary fossil plants of Europe with those living on the spot now, we
shall be struck with differences of about the same value as those
already mentioned between the eastern and western coasts of the
continents under the same latitudes. Compare, for instance, a list of
the fossil trees and shrubs from Oeningen, with a catalogue of trees
and shrubs of the eastern and western coasts, both of Europe, Asia,
and North America, and it will be seen that the differences they ex-
hibit scarcely go beyond those shown by these different florae under
the same latitudes. But what is quite extraordinary and unexpected,
is the fact that the European fossil plants of that locality resemble
more closely the trees and shrubs which grow at present in the east-
ern parts of North America, than those of any other part of the
world ; thus allowing us to express correctly the differences already
mentioned between the vegetation of the eastern and western coasts
of the continents, by saying that the present eastern American
flora, and I may add, the fauna also,* and probably also that of
Eastern Asia, have a more ancient character than those of Europe
and of Western North America. The plants, especially the trees
and shrubs growing in our days in this country and in Japan, are,
as it were, old-fashioned ; they bear the mark of former ages; a
peculiarity which agrees with the general aspect of North America,
the geological structure of which indicates that this region was .a
large continent long before extensive tracts of land had been lifted
above the level of the sea in any other part of the world.

The extraordinary analogy which exists between the present flora

* The characteristic genera Lagomys, Chelydra and the large Salamanders with per-
manent gills remind us of the fossils of Oeningen, for the present fauna of Japan, as
well as the Liquidambar, Carya, Taxodium, Gleditschia, etc. etc.

THE NORTHERN VEGETATION COMPARED, ETC. 151

and fauna of North America, and the fossils of the miocene period
in Europe, would also give a valuable hint with respect to the mean
annual temperature of that geological period.

Oeningen, for instance, whose fossils of all classes have perhaps
been more fully studied than those of any other locality, could not
have enjoyed during that period a tropical or even a sub-tropical cli-
mate, such as has often been assigned to it, if we can at all rely upon
the indications of its flora, for this is so similar to that of Charleston,
South Carolina, that the highest mean annual temperature we can
ascribe to the miocene epoch in Central Europe must be reduced to
about 60° Fah. ; that is to say, we infer from its fossil vegetation that
Oeningen had, during the tertiary times, the climate of the warm
temperate zone, the climate of Rome, for instance, and not even that
of the northern shores of Africa. We are led to this conclusion by
the following argument : — The same isothermal line which passes at
present through Oeningen at the 47th degree of northern latitude,
passes also through Boston, lat. 42°. Supposing now, (as the geolog-
ical structure of the two continents and the form of their respective
outlines at that period seem to indicate,) that the undulations of the
isothermal lines which we notice in our days existed already during the
tertiary period, or in other words, that the differences of temperature
which exist between the wes JJL-rn shores of Europe and the eastern
shores of North America, were the same at that time as now, we shall
obtain the mean annual temperature of that age by adding simply the
difference of mean annual temperature which exists between Charles-
ton and Boston, (12° Fah.,) to that of Oeningen, which is 48° Fah.,
as modern Oeningen agrees almost precisely with Boston, making it
60° Fah. ; far from looking to the northern shores of Africa for an
analogy, which the different character of the respective vegetations
would render still less striking. The mean annual temperature of
Oeningen during the tertiary period would not therefore differ more
from its present mean, than that of Charleston differs from that of
Boston.

This old-fashioned look of the North American forests goes also to
show the intimate connection there is all over the globe between the
physical condition of any country, and the animals and plants peculiar

152 LAKE SUPERIOR.

to it. But far from supporting the views of those who believe that
there is a causal connection between these features of the creation,
we must, on the contrary, conclude from the very fact that there are
so many special thoughtful adaptations for so long successive periods
in their distribution, that those manifold relations could only be intro-
duced, maintained and regulated by the continuous intervention of
the Supreme Intelligence, which from the beginning laid out the plan
for the whole, and carried it out gradually in successive times.

What is true of plants is also true of animals ; we need only re-
member that it is in North America that Lepidosteus and Percopsis
are found ; that species of Limulus occur along the Atlantic shores ;
and that Trigonia and Cestracion live in New Holland along palaeozoic
rocks.

OBSERVATIONS ON THE VEGETATION OF THE NORTHERN
SHORES OF LAKE SUPERIOR.

THE vegetation of the Northern shores of Lake Superior agrees so
closely with that of the higher tracts of the Jura, which encloses the
lower and middle zone of the subalpine region, that on glancing at
the enumeration below, one is astonished to find so great a number
of species entirely identical. Making full allowance for the influ-
ence of the lake, and leaving out of consideration a small number
of species peculiar to North America, there remains about Lake
Superior a subalpine flora which is almost identical with that
of Europe, with which it is here compared. Although this fact
is very striking, it is nevertheless in accordance with the general
laws of botanical geography, and is another proof that the vegeta-
tion of the two continents becomes more and more homogeneous the
more we advance northwards.

I have divided the catalogue of the phaenogarnous plants collect-
ed about Lake Superior into four lists : The first containing such
plants as are really subalpine in their character, or correspond to
those of the forests of the lower Alps ; * the second containing the
plants of the lake proper, or the aquatic plants ; f the third comprising
the plants purely American, | and the fourth the cosmopolitan plants,
or those which extend beyond the subalpine region. In the different

* All the plants enumerated below were collected by me and some of the gentlemen
of our party, who took particular interest in the study of botany, as C. G. Loring, Jr.,
T. M. Lea, J. E. Cabot and Dr. Keller. They were for the most part determined on
the spot with the excellent work of my friend Prof. Asa Gray on the Botany of the
Northern United States. Afterwards my collection was revised by Dr. Gray himself,
and by Messrs. Leo Lesquereux and Ed. Tuckerman ; the latter of whom examined
the lichens with particular care, while Mr. Lesquereux revised more particularly the
mosses, and furnished me with very minute information about the distribution of plants
in Switzerland, to which I had myself paid a good deal of attention in former years.
I owe it nevertheless to his contributions upon this particular point, that I have been
able to carry my comparisons of the plants of Lake Superior and Central Europe so
much into detail as I have done. Prof. Gray has also furnished me with very import-
ant documents respecting the distribution of many species, beyond the regions I have
examined myself. The general views, however, derived from this study, as I have
expressed them in the preceding and following pages, so far as they are new, are my
own.

f This and several other plants of this list have a rather extensive range southwards .
but this seems to be in accordance with the general direction of the mountain chains
and the form of the American continent itself, in which both animals and plants pecu-
liar to the arctic and temperate zones extend farther south, than their analogues in
the Old World.

It is a remarkable fact, that the family of Caryophyllaceaa, so extensive in
the alpine regions of Europe, has so few representatives about Lake Superior.
The reason is, that the Caryophyllacefe, like the Cruciferte, belong for the most
part, to the alpine flora properly, and to the flora of the plains, and are missing
in the subalpine, or intermediate regions.

The Malvaceae are generally plants of warm countries. This family is not
represented about Lake Superior by a single species, nor are the intermediate
families between this and the Leguminosse. The Leguminosse themselves are
very rare, since they are, like the Caryophyllaceaa, plants of the higher Alps, or
of the plain. The Rosaces, on the contrary, generally extensive in the sub-
alpine regions of Europe, are also abundant around Lake Superior.

These Orchideie, and several more which correspond by their forms to those
of Europe, or are even identical with them, characterize all the subalpine re-

descend towards the warmer latitudes, where they assume more and more
brilliant colors, whilst their flowers become larger and more diversified.

The Equisetaceae, the Ferns, and the Lycopodiaceae of Lake Superior are
almost absolutely the same species as those of the subalpine region of Europe.
As we descend the scale of the vegetable kingdom under higher latitudes, vege-
tation seems to follow the sides of an angle, as it were, which become convergent
about the zone of pine forests. Thus the Lichens and the Mosses are already
entirely the same species here as in Europe, and it will be sufficient to make a
single list of them, without indicating the corresponding European species,
since all are identical. Few Hepaticce are also enumerated.

To this first enumeration of the species of plants occurring about
Lake Superior, and which belong to the subalpine region as such, we
subjoin a list of species, which cannot strictly be referred to this one,
though they occur in it. They are few in number and still fewer
of them belong to the Cryptogamous plants.

It seems at the first glance to be a contradiction to unite in a separate table
the aquatic plants of the lakes, leaving as characteristic of the subalpine region
the aquatic plants of the peat-bogs. That is, however, not the case, for the
peat-bogs and the plants which form them, (the peat-bogs with Sphagna at
least,) never descend below the Pine region, which they follow in its whole ex-
tent, whilst lake and marine plants follow the shores in various latitudes. The
former being of course under the direct influence of the temperature, the latter,
on the contrary, being more dependent upon the moisture of the soil.

Europe.

* Besides the genera which have no representatives at all in Central Europe, there
are several introduced in this list which have only remote analogues, or indeed, real
representatives ; but in such countries of the Old World which are far distant from
the mountain chains, the vegetation of which has been compared here with that of

We cannot consider this plant as cor-

shores of the Adriatic. These
two species differ in form and
habitat.

From these various tables it is easy to see that the vegetation of the northern
shores of Lake Superior is perfectly similar to the subalpine vegetation of
Europe, at that zone which, in the Jura for instance, extends from 3,000 to
3,500 feet, and which in the Alps extends from 3,500 to 5,000 feet. Now
removing some plants of the lakes, and some few peculiar American types,
the subalpine flora remains in its integrity, and will be found to form chiefly
the vegetation about the northern shores of Lake Superior.

SPECIAL COMPARISON.

Distribution of the Trees and Shrubs of Switzerland from the Plains
to the Summit of the Mountains, compared with those of North
America.

As it is easier to perceive the regular order of succession of the
different growths which follow each other along the slope of a moun-
tain, and to determine under such circumstances the precise limits of
their distribution, than to ascertain the natural range of the corres-
ponding vegetation northwards over extensive tracts of land, in level
countries, I shall first introduce a general picture of the arbores-
cent vegetation of the Swiss mountains, before I undertake to show
that it agrees most minutely in its internal arrangement with that of
the lake districts.

The vines which cover the margins of the Lake of Neuchatel, 1338
feet above the level of the sea, characterize, of course, the lower

180 LAKE SUPERIOR.

regions, which we call, for that reason, the region of vineyards. The
trees which are cultivated there, the mulberry, peach, apricot, and
even the fig in the warmest places, are all exotic. All fruits of the
temperate zone, however, succeed there perfectly well, and among the
wild trees and shrubs which characterize this zone, we find especially
Rubus : Rubus corylifolius, Rubus fruticosus L., Rubus tomentosus
W. ; some Roses : Rosa pimpinellitblia L., Rosa eglanteria_L., Rosa
alba L. ; the Pyrus communis L., the Crataegus torminalis L., Mes-
pilus germanica L., and Mespilus eriocarpa DO. The most common
ornamental shrubs which are cultivated there on level ground, are
the Philadelphus coronarius and the Lilac, which we find as far as the
lower valleys of the Jura. This zone is almost entirely cultivated,
and has few indigenous trees. We meet now and then with forests
of oak trees (Quercus Robur .L.,) and of chestnut trees (Castanea
vesca).*

Immediately above this horizon, at an elevation of some hundred
feet higher, from 1600 to 1700 feet begins the zone of oaks, which
ascends somewhat into the valleys. The two species of this genus,
the Quercus Robur L., and the Quercus sessiliflora Sin., grow in
the same places ; the latter ascends, however, a little higher, and
occurs but very thinly, it is true, in the Val de Ruz, and in the
Val de Travers. On the slopes of the Alps it ascends 1,500 feet
higher, especially in sheltered valleys. The shrubs and trees which
follow these are not numerous, (for the vegetation of the oak
forests, like that of the pine trees, excludes other trees ;) they are
the hedge-plants, which are found as far as the region of the pines,
(Viburnum Opulus L. et Viburnum Lantana i.) ; the yew, (Taxus
baccata L.} ; the box-tree, (Buxus sempervirens L.~) ; the hornbeam,
(Carpinus betulus i.,) very rare ; the alder, (Alnus glutinosa
G-certn.} At the margins of the brooks, some briars, the honeysuckle,
(Lonicera Caprifolium,) cultivated ; the buckthorn, (Rhamnus ca-
tharticus _L.) ; the holly, (Ilex Aquifolium). The fruit trees culti-
vated with the greatest success in this zone, are the walnut, the
apple, the pear, &c.

* Along the margin of the lakes grow the Populus nigra and several species of willows,
which are characteristic, but have no direct affinity with the localities in which they
occur. The Clematis Vitalba, on the contrary, attaches itself to the trees of the region
of the vines and oak trees, but never ascends higher.

VEGETATION OF THE NORTHERN SHORES. 181

Between the region of the oak and that of the beech, we have at a
height of 2,000 feet, as a transitory zone, a narrow tract characterized
by the wild cherry tree and the Pinus sylvestris, which is, however,
particularly adorned by a large variety of shrubs. To this zone
belongs in the first place the linden tree, (Tilia microphylla f7"., and
Tilia platyphylla Scop.') ; three maples, (Acer opulifolium L., Acer
platanoides L., and Acer campestre £.) ; the Evonymus europreus L.,
Cerasus Padus DC., Prunus spinosai., Crataegus Aria £.,Mespilus
oxyacantha, Lonicera Periclyraenum L., Sambucus nigra L., Cornus
mas L., Cornus sanguinea L., Viscum album L., Ligustrum vulgare
L., Daphne Cneorum L., Populus treniula L., with the introduced ./Es-
culus Hipocastanum, which succeeds in this zone better than anywhere
else. This is the region of shrubs, properly speaking, with which is
mingled the beech tree, whose zone, however, is more extended, and
ascends in the Jura to 3,500 feet, and to 4,000 feet in the Alps.

To the region of the beech tree, which extends over a thousand
feet of vertical height, from 2,500 to 8,500 feet, belong the following
shrubs: — Rhaninus Frangula L., Cytisus Laburnum L., Rubus saxa-
tilis L., Rubus caesius L., Rubus idreus L., Rosa eglanteria_Z/., Rosa
villosa L., Rosa canina i., Rosa rubiginosa L., Crataegus Amelan-
chier L., Lonicera Xylosteum L., Sambucus Ebulus L., Daphne
Mezereum L., Daphne alpina L., Daphne laureola L., Ulmus
cainpestris L., Corylus Avellana L.

The region of the pines or Coniferse extends from 3,500 feet to
4,500 feet in the Jura, and to 6,000 feet in the Alps. It is well
characterized in its lower and middle parts, where we find Frax-
inus excelsior L., Abies excelsaDG"., Abies pectinata DC., Juniperus
communis L., and in the higher part the Pinus Cembra L., Pinus
Pumilio CluSj Larix europaea DC. In this zone live the Betula alba

cumbens L., Empetrum nigrum L., Acer pseudoplatanus L.

Above all these we meet already in the Jura the Rhododendrons
and the Salix herbacea, which belong truly to the alpine flora char-
acterized by all those handsome plants covered with a light cotton
down, which we find along the margin of the glaciers in the Alps,
and as high as the uppermost limit where all vegetation ceases some-
what suddenly, at a level of about 8,000 feet above the level of the
sea.

Trees of the Lake Superior Region.

We may place at about 40° northern latitude the zone of vegeta-
tion, which in America corresponds to the upper limit of the cultiva-
tion of the vine, as we observe it on the banks of the Swiss lakes.
At about this latitude the family of the Magnoliacete dies out, though
we may still meet the Magnolia glauca in the swamps, as far as the
43° N. lat., and though the tulip tree still flourishes there. This is
also the northern limit of the Anonacese, Melastomacege, Cactaceae,
Santalacece, and Liquidambar ; and though in Europe we have no
representatives of these families, it is easy to perceive, on reflecting
upon the examples just mentioned, that the limits of vegetation under
consideration are natural, and correspond to each other, though
characterized in the two continents by different plants. Again, the
numerous species of wild vines which America produces, although
they do not extend farther northwards than the cultivation of the
vine in Europe, yet prosper on this continent in a colder climate.

The State of Massachusetts, with its long arm stretched into the
ocean eastwards, or rather the region extending westward under the
same parallel through the State of New York, forms a natural limit
between the vegetation of the warm temperate zone, and that of the
cold temperate zone, whose forests G. B. Emerson, Esq., has so well
described in his admirable Report upon the Trees and Shrubs of
Massachusetts. With this book, we may become well acquainted
with the arborescent vegetation of the zone which corresponds to the
horizon of oaks and shrubs in the Jura ; so that I need not enumer-
ate these characteristic species. Not only is this also the northern
limit of the culture of fruit trees, but this zone is equally remarkable
for the great variety of elegant shrubs which occur particularly

VEGETATION OF THE NORTHERN SHORES. 188

on its northern borders, where we find so great a variety of
species belonging to the genera, Celastrus, Cratsegus, Ribes,
Cornus, Hamamelis, Vaccinium, Kalmia, Rhodora, Azalea, Rho-
dodendrum, Andromeda, Clethra, Viburnum, Cephalanthus, Prinos,
Dirca, Celtis, &c. I shall only add, that in the latitude under
which the St. Lawrence winds its course from the great Canadian
lakes, and takes a more independent course north-eastwards, we
perceive already great changes in the growth of trees. About Niag-
ara, or rather somewhat farther north along the northern shores of
Lake Ontario, and the hills which rise above Toronto, the following
species begin to disappear : Sassafras officinale, (I have not seen this
species north of Table Rock,) Juglans nigra and cinerea, Carya alba
and amara, Castanea americana, Quercus alba and Castanea, Pla-
tanus occidentalis. Tilia americana, (this species occurs, however,
as far north as Sturgeon Bay, on Lake Huron,) Rubus odoratus.
Though the Beech is extensively distributed among the forests of this
zone, we cannot but be struck with their splendid growth further north,
where the Elm, Red Oak, Hornbeam, Hop-hornbeam, several species
of Birches, various Maples, Ashes, Wild Cherries, &c., &c., more
or less mixed with Coniferse, form the most beautiful forests of the
temperate zone, particularly remarkable for their diversified shades
of green and dark foliage, and which almost uniformly cover the
ground along the shores of the Great Lakes as far as Lake Superior,
the Coniferae gradually coming in in a larger proportion to the suc-
cessive exclusion of the trees with deciduous leaves. As soon as we
reach Mackinaw we find the Beech has almost entirely disappeared,
or become so dwarfish as no longer to be a handsome tree, while
Ostrya, Carpinus, Betula populifolia, Quercus rubra, and indeed all
Cupuliferse are entirely gone, and the Canoe-Birch, the Black Ash,
with- Pinus balsamifera, alba, nigra, Larix americana, Pinus Strobus,
Sorbus americana, and some Poplars on the lake shore, form the mass
of forests, with a few low shrubs among them, such as Arctostaphylos
Uva-ursi, Vaccinium, Chiogenes, &c. This zone, which corresponds
to the horizon of Pines in the Jura, extends all along the northern
shores of Lake Superior. North of Fort William are extensive
forests of Pinus Banksiana, with Pinus resinosa and Strobus. We
noticed no Cupuliferae beyond Batcheewauaung Bay, and we learnt

184 LAKE SUPERIOR.

that but a few dwarfish Red Oaks are seen in the Island of Michipi-
cotin ; but the Elm is still handsome about Fort William, though it is

7 O

very scarce in other parts of the northern shores.

The shores of Nipigon Bay, the northernmost point we visited, are
covered with Pine forests, with a few Ashes and Maples, and here and
there a Sorbus americana among them. At this latitude, the 49°,
we had therefore not yet reached the zone of the true alpine vegeta-
tion, and remained for the whole extent of our journey within the
limits of the sub-alpine flora.

The highest point which we visited, the summit of a mountain upon
St. Ignace Island, which we called Mount-Cambridge, afforded the
following harvest for our herbarium : — Abies balsamea, Abies alba,
Betula papyracea, Alnus viridis, Sorbus americana, Amelanchier
canadensis, Acer montanum, Diervillea trifida, Sambucus pubens,
Rhus Toxicodendrum, Vaccinium uliginosum, Corylus rostrata, Lin-
naea borealis, Cornus canadensis, Spiraea opulifolia, Salix, Cory-
dalis glauca, Epilobium angustifolium, Polygonum ciliare, Melam-
pyrurn, Clintonia borealis, Stereocaulon paschale, Gyrophora hirsuta,
Cladonia pyxidata, and rangiferina, Parmelia tiliacea and Sphagnum
acutifolium.

From this list it is obvious, that even a thousand feet of height
will introduce very slight differences in the vegetation of these re-
gions. For, though Mount Cambridge is about a thousand feet above
the level of the lake, its whole slope is covered with the same vege-
tation which occurs at the very level of the lake.

This fact would seem in flat contradiction with the general laws of
the geographical distribution of plants, to which we have alluded above,
but for the presence of the lake itself and its peculiar character.

So large a sheet of so deep water as Lake Superior, preserving all
the year round a very equable and low temperature even on its
shores, which are generally very precipitous, must of course influence
greatly the temperature of the main land in its immediate vicinity, at
considerable heights above its surface.

There is, therefore, nothing very surprising in our finding so uniform
a vegetation at rather considerable heights above the surface of the
lake and on its immediate shores.

This fact is to be attributed to the equalizing local influence of the

VEGETATION OF THE NORTHERN SHORES. 185

lake, and does not form an exception to the law of distribution, and
change of the character of vegetation in the interior of continents, upon
the slopes of high mountains ; for we have, even a few degrees farther
south, in the same continent, a striking example of the fixity of these
laws, in the White Mountains, which are sufficiently distant from the
sea-shore, and not surrounded by any large sheet of fresh water, so
that the zones of vegetation are very well marked on their slopes,
and can be traced in gradual succession beyond the range of the
Mountains proper to the level, where the vegetation has the char-
acter which distinguishes it, in this latitude, near the level of the sea.

In the vicinity of the White Mountains, the changes of vegetation
are rather conspicuous, owing to their gradual elevation above the
surrounding flat country, and also to the more sudden rise of several
of their peaks. We no sooner begin to ascend the head waters of
the Connecticut valley towards Littleton, than the forest vegetation
begins to assume a different character from what it has lower down in
the main valley nearer the sea. Juglans cinerea and Carya porcina
disappear in that village. The oaks also are fewer and smaller.
The mountain maple, which is not found below, here makes its
appearance. The following trees may be seen between Windsor and
Littleton : — Abies Canadensis, Pinus strobus, Thuya occidentalis,
Larix Americana, Platanus occidentalis, Fagus ferruginea, Compto-
nia asplenifolia, Betula populifolia, B. lenta, B. excclsa, B. papy-
racea, Quercus alba, Q. rubra, Q. bicolor, Ulrnus Americana, Car-
pinus Americana, Ostrya Virginica, Fraxinus alba, Populus trernu-
loides, Tilia Americana, Acer saccharinum, A. montanum, A. Penn-
sylvanicum. The chestnut has already disappeared at Windsor,
where the height above the level of the sea is three hundred feet.

From Littleton, eight hundred and thirty feet above the sea, to
Fabyan's, which is fifteen hundred feet,* we notice Abies alba,
A. balsamifera, A. Canadensis, Pinus strobus, Larix Americana,
Tilia Americana, Fraxinus alba, Acer saccharinum, A. monta-
num, A. Pennsylvanicum, Ulmus Americana, Sorbus Americana,
Betula excelsa, B. papyracea, B. populifolia, Alnus incana, Cornp-

* This and the following measures were ascertained barometrically by Professor

A. Guyot.

tonia asplenifolia, &c. The Cupuliferae have disappeared; Pinus
rigida, also, is no longer observed, and thus vegetation continues
from Fabyan's to a level of two thousand and eighty feet, where
the pine vegetation forms the larger proportion of the features of the
forest.

This height of two thousand and eighty feet is a very natural
level in the chain of the White Mountains, and especially on the
slope of Mount Washington. It indicates the horizon where the
slope begins to be much steeper, and where the variety of trees
combined in the forests is greatly reduced ; for above this level to
the height of four thousand three hundred and fifty feet we may say
that the vegetation consists entirely of Abies alba and balsamea and
Betula excelsa and papyracea, which grow gradually more and more
stunted, till at the height of four thousand three hundred and fifty
feet, those species even, which form tall, splendid trees one or two
thousand feet lower, appear here as mere shrubs, low bushes, with
crooked branches so interwoven as almost entirely to hedge up the
way, excepting in places where a bridle-path has been cut through.

Above this level the mountain is naked, and many fine plants make
their appearance which remind us of the Flora of Greenland, and
many of which grow on the northern shores of Lake Superior, such
as Arenaria Grcenlandica, Vacciniuin caespitosum, uliginosurn, &c.

The summit of the mountain, at the height of six thousand two
hundred and eighty feet, produces several plants which have no
representatives south of Labrador. Such are Andromeda hypnoides,
Saxifraga rivularis, Rhododendron lapponicum, Diapensia lapponica.

Before leaving this subject I ought to make an additional remark
about the identity of so many plants which are common to both
continents. It is a general fact, that the farther north we proceed,
the greater is the primitive uniformity of the plants, as well as the
animals, in both hemispheres ; so much so, that the arctic flora and the
arctic fauna are identical, not only in their general character, but also
in almost all the species which characterize that region as a natural
botanical and zoological province. But there are a great many
plants and animals occurring in the temperate zone, which are equally
identical in Europe and America, and which, nevertheless, do not

VEGETATION OF THE NORTHERN SHORES. 187

belong originally to both hemispheres,* but were introduced into
America since the settlement of Europeans in this part of the world,
many of which, though foreigners, have spread so extensively, as
to be generally considered as natives of this country. But if we
carefully examine their distribution, we soon perceive that they follow
everywhere the tracks of civilization, and occur nowhere except in
those districts and in those soils where the hands of white men have
been at work. In such localities, however, they have almost com-
pletely replaced the native weeds, which have disappeared before
them as completely as the Indian tribes have disappeared before the
pressing invasion of the more civilized nations. These plants are
chiefly such as occur in Europe by the road-sides, or near the habita-
tion of man, and which to a certain degree may be considered as sat-
ellites of the white race. Their occurrence is particularly striking
along the new lines of railroads, where they settle almost as soon as
the tracks are marked out, and increase in a few years so rapidly
within the enclosure of the roads, as to suppress the primitive vegeta-
tion almost completely, with the exception of a few hardy natives
which resist the new invaders. Several of these plants occur natur-
ally, in America, in more northern latitudes. Nevertheless, I have
no doubt that in most cases they were introduced into the more
temperate and cultivated latitudes from Europe, rather than from
their northern residence in America.

The following list of these plants was chiefly made from an
examination of the railroad tracks between Boston and Salem, in
company with that liberal cultivator of botany, Hon. John A. Lowell,
and also from materials collected during an excursion made with

* I do not wish by this remark to be understood as intending to deny the identity of any
native plant in the temperate zone of Europe and America. I know^that many species
which occur very far north, and are there truly identical in both continents, are also
found among the plants of the temperate zone on the two sides of the Atlantic ; but
there still remains a large number, the identity of which ought to be ascertained by
direct comparison of authentic specimens from the two continents, before it can be
finally admitted that there" is no specific difference between them. As such, I may
mention Hepatica triloba, Geranium Robertianum, Oxalis Acetosella, Spiraea Aruncus,
Circoca lutetiana, Calystegia sepium, Agrimonia Eupatoria, Majanthemum bifolium,
and many aquatic plants. The identity of these with European species seems to
me the more questionable, as the freshwater animals, the fishes, mollusks and insects
differ specifically throughout.

It is still a question whether all these plants originate from Europe, as many
of them occur there in the same circumstances as in this continent, under the
immediate influence of agricultural improvements, and might have followed the
Caucasian race of men from farther east, in his migrations over the temperate
zone of Europe. Various other remarks respecting the vegetation of this con-
tinent may be found above, in the course of the Narrative, pp. 10, 13, 19, 89.
Many interesting remarks upon the foreign vegetation of this continent may
also be gathered in Kami's Travels in North America. Quite a number of
European insects have also been introduced into this country with those plants,
among which I may mention some showy butterflies, as Vanessa atalanta, Car-
dui and Antiopa, which are very erroneously considered by some entomologists
as native Americans.

III.

CLASSIFICATION OF ANIMALS FROM EMBRYONIC
AND PALEOZOIC DATA.

FOR several years I have been in the habit of illustrating, in mj
public lectures and elsewhere, principles which have not yet been
introduced in our science, and to which I feel it my duty to call
attention in a more formal manner on this occasion, as during our
excursion we had several opportunities to discuss them at length.
These remarks will form an appropriate introduction to the lists of
the animals found about Lake Superior, which are given below.

The principle which has regulated our classifications for the last
half centurv, is that which Cuvier worked out by his anatomical
investigations ; I mean the arrangement of the whole animal kingdom
according to the natural affinities of animals as ascertained by the
investigation of their internal structure. This fruitful principle,
applied in various ways, has produced a series of classifications,
agreeing or differing more or less in their outlines, but all resting
upon the idea, that a certain amount of anatomical characters may
be easily ascertained, expressing the main relations which exist natu-
rally among animals, and affording a natural basis for classification.
Structure, therefore, internal as well as external, is, according to the
principles of Cuvier, the foundation of all natural classifications ; and
undoubtedly his researches and those of his followers have done more,
in the way of improving our natural methods, than all the efforts of
former naturalists put together ; and this principle will doubtless
regulate, in the main, our farther efforts.

Nevertheless, so much is left in this method to the arbitrary deci-
sion of the observer, that it would be in the highest degree desirable

192 LAKE SUPERIOR.

to have some principle by which to regulate the internal details of
the edifice.

We may indeed form natural divisions simply from structural evi-
dence, bring together all fishes as they agree in the most important
details of their structure, and combine all reptiles into one class, not-
withstanding the extreme differences in their external form. We may
also recognize the true affinity of whales, and bring them together
with other Mammalia, notwithstanding their aquatic habits and their
fish-like form ; we may even subdivide those classes into inferior
groups upon structural evidence, and thus introduce orders, like the
Quadrumana, Carnivora, Rodentia, Euminantia, &c., &c., among
Mammalia. But we are at once at a loss how to determine the relative
value of those groups, and to find a scale for the natural arrange-
ment of further subdivisions. After having, for example, circum-
scribed the Carnivorous Mammalia into one natural family, how are
we to group the minor divisions like that of the swimming Carnivora,
the Plantigrada and the Digitigrada ; or, after circumscribing the
reptiles into natural groups like those of Chelonians, Saurians,
Ophidians and Batrachians, how shall we, for instance, arrange the
various types of Batrachians ? To those who have been familiar
with our proceedings in all these attempts, it must be evident that
the grouping of our subdivisions has been almost arbitrary and en-
tirely left to our decision without a regular guide. We have, it is
true, subdivided the Batrachians into the more fish-like forms which
preserve their gills and tails, or at least their tails ; and into another
group, containing those which undergo a complete metamorphosis ; but
it has not yet occurred to naturalists to take this metamorphosis as the
regulating principle of classification, to arrange genera according to
their agreement with certain degrees of development, in the natural
order of changes which the higher of these animals undergo. Now
it is my firm belief, that such a new principle can be introduced into
our science ; that methodical arrangement may be carried into the most
minute details, without leaving any room for arbitrary decision. Pro-
teus, Menobranchus, Amphiuma, Triton, Salamandra will hereafter
have a natural place in our classification, which will be commanded
by embryology, and no longer be left to a vague feeling that aquatic
animals are lower than amphibious and terrestrial ones, and that the

CLASSIFICATION OF ANIMALS. 193

retaining of the gills indicates a lower position than their disap-
pearance. *

Of course, in the outset, we do not find sufficient data to trace this
arrangement throughout the animal kingdom, and to make the prin-
ciple which I have just mentioned the ruling law of nice classical
arrangement. But until such sufficient knowledge is acquired, let me
show that my principle does in fact apply to all classes of the animal
kingdom, and will at once contribute to improve all their subdivisions.
Among Mammalia, for example, we shall continue to give the aquatic
carnivorous animals a lower position among Carnivora, but no ouger
simply because they are aquatic, but because they are webfooted, as
the webfoot is the earlier form of the limbs in all Mammalia whose
embryonic development has been traced. We shall be led, for similar
reasons, to deny the bats the high position which has been assigned
to them, and to combine them closer with the Insectivora. We shall
separate the manatees from their present relations and combine them
with tapirs, elephants, &c., as they are rather webfooted Pachy-
derms, than true Cetaceans. f

* These views were fully illustrated in a series of twelve lectures upon Comparative
Embryology, delivered before the Lowell Institute during the last winter, and reported
for the Daily Evening Traveller, and afterwards published as a separate pamphlet.

f These aphorisms will be justified by a more elaborate illustration of the peculiar
changes which the limbs of Mammalia undergo during their embryonic growth, as far
as I have been able to trace them, in various animals. It may suffice, for the present,
for me to say here, that in all young embryos of Mammalia which I have recently had
an opportunity to examine, I have found the extremities arising as oblong tubercles,
flattened at their extremities, spreading more and more into the form of hemispherical
paddles, in which the changes in the cellular growth gradually introduce differences
upon the points where the fingers are to be developed. But for a longer time they re-
main combined in a common outline, and the microscopic structure of the tissues alone
indicates the points of growth ; and even after the fingers have been fully sketched out,
they remain for a certain time united by a common web, which is successively reduced
as the fingers grow longer and thicker.

It is very remarkable how uniform, and indeed how identical in form and structure the
anterior and posterior extremities are in the beginning, whatever may be the difference
at a later period of growth. Thus, for instance, there is not the slightest difference be-
tween the anterior and posterior extremities of the bat, in the early stages of develop-
ment. The wing is then a very short limb, terminated by a flat, webbed paddle, of a
semicircular form, identical in development, size and form with the hinder extremity,
and differing in no respect from the appearance of the hand and foot in young human
embryos, or in embryos of cats, dogs, squirrels, hares, rabbits and pigs, and bearing

194 LAKE SUPERIOR.

Among birds we shall also avail ourselves of the discovery I made
last year, that embryos of birds have web-feet and web-wings, and no
longer consider Palmipedes as forming a natural group by themselves,
but allow the possibility of having several natural groups of birds,
beginning each with web-footed forms. Every one who is conversant
with the natural history of birds must have been struck with the great
diversity of features in birds united in our systems under the head
of Palmipedes. Taking all birds together, we hardly notice among
them greater differences than those which exist between the various
families of Palmipedes, which are, confessedly, brought together upon
no other character than the webbed form of their feet ; though among
them we have birds of prey, such as the gulls, and others, which
seem to stand by themselves unconnected and without any analogy
with any other family, such as the swans, geese, and ducks ; and
again, the pelicans and the genera allied to them, and also the divers.
It can hardly be understood why birds so widely different should be
brought together ; and indeed, their reunion would long ago have
been given up, had it not been for the difficulty of finding characters
to separate them, and for the strong impression, that the similarity
of the structure of their feet should overrule the other characters.

But now, since it is known that birds of the most heterogeneous
character in the structure of their legs, in their adult form, have,
when very young, identical legs, whether they belong to the type
of hawks, or to that of crows, or to that of sparrows, or to that of swal-
lows, or to that of pigeons, or to that of hens, or to that of waders,
or to that of taue Palmipedes, — when we know all these types to have
an identical development of their legs, and, I may add also, of their
wings, — for the young wing is equally a small, webbed fin, — there
can be no longer any doubt left upon the impropriety of combining
any two families of adult birds solely on the ground of their legs
having webbed feet.

It is a fact, too well known in zoology, that different families will

the same relation to the extremities of birds, in which also legs and wings are de-
veloped according to the same pattern.

These facts have been partly described in my Lectures on Comparative Embryology,
and more extensively illustrated in a paper laid before the American Association for the
advancement of Science, in Cambridge, August, 1849. See also Narrative, p. 35.

CLASSIFICATION OF ANIMALS. 195

repeat, in the same class, the characteristic changes which are pecu-
liar to the whole family, to require any further argument to show that
Palmipedes are not, necessarily, a natural division ; and though we
may fail for the present in rearranging the families of this class into
natural orders, I trust after these remarks, more importance will yet
be attached, and more attention paid in future, to the fact that Pal-
mipedes, as they are now characterized, have very different types of
wings and bills. I have, for my own part, been strongly impressed
with the resemblance which exists between gulls and frigate birds,
and the birds of prey, of the hawk and vulture families, in which the
toes are by no means so completely distinct as they are among other
birds. And, far from considering birds of prey as the highest family
among birds, I would only consider them as highest in the series
which includes simultaneously Procellaridoe and Laridse. Whether
the family of pelicans belongs to this group or not, I am not prepared
to say ; but, at all events, the fact of their preserving their four toes
in one continuous web shows them to rank lowest among birds.

Again, among reptiles there will no longer be a foundation for
any arrangement resting merely upon impressions ; thus the terres-
trial turtles will stand higher than the freshwater, and these again
higher than the marine ; and among Batrachians, which are best
known in their embryology, we can already arrange all the genera
in natural series, taking the metamorphosis of the higher as a
scale, and placing all full-grown forms in successive order, accord-
ing to their greater or less resemblance to these transient states.
Even the relative position of toads and frogs may be settled with
as much internal evidence as any other question of rank in wider
limits, merely upon the difference of their feet.

In my researches upon fossil fishes I have on several occa-
sions alluded to the resemblance Avhich we notice between the
early stages of growth in fishes, and the lower forms of their families
in the full-grown state, and also to a similar resemblance between the
embryonic forms and the earliest representatives of that class in the
oldest geological epochs ; an analogy which is so close, that it involves
another most important principle, viz., that the order of succession in
time, of the geological types, agrees with the gradual changes which
the animals of our day undergo during their metamorphosis, thus

giving us another guide to the manifold relations which exist among
animals, allowing us to avail ourselves, for the purpose of classification,
of the facts derived from the development of the whole animal king-
dom in geological epochs, as well as the development of individual
species in our epoch. But to this most fruitful principle I shall have
hereafter an opportunity of again calling attention.

At present there is some doubt among zoologists, as to the respect-
ive position of the classes of worms, insects and Crustacea, some
placing the Crustacea, and others the insects uppermost. Embryonic
data may afford the means of settling this question ; we need only
remember the extensive external changes which insects undergo from
their earliest age, and the many stages of structure through which
they pass, whilst Crustacea are less polymorphous during the different
periods of their life, and never obtain an aerial respiration, but
breathe through life with gills, which many larvse of insects cast before
they have accomplished their metamorphoses, to be satisfied that the
afiinity between Crustacea and worms is greater than between worms
and insects, especially if we consider the extraordinary forms of some
parasitic types of the former. As soon as the higher rank of insects
among Articulate is acknowledged, many important relations, which
remain otherwise concealed, are at once brought out. The whole
type of insects in its perfect condition, contains only aerial animals,
while the Crustacea and worms are chiefly aquatic. And if we com-
pare these three classes in a general way, we cannot deny the cor-
rectness of the comparison as made by Oken, that worms corres-
pond to the larval state of insects, Crustacea to their pupa state,
and that insects pass through metamorphoses corresponding to
the other classes of Articulata. The little we know about the
embryology of worms will already satisfy us that the earlier
stages of the higher of these animals agree most remarkably in
character with such of them as, from other reasons, we have been
in the habit of considering as the lowest, thus affording another
prospect of regulating finally the arrangement of those curious
animals entirely upon embryonic data.

If there is any internal evidence that the whole animal kingdom is
constructed upon a definite plan, we may find it in the remarkable

agreement of our conclusions, whether derived from anatomical evi-
dence, from embryology or from palaeontology. Nothing, indeed,
can be more gratifying than to trace the close agreement of the
general results derived from the study of the structure of animals,
with the results derived from the investigation of their embrvonic

O */

changes, or from their succession in geological times. Let anatomy
be the foundation of a classification, and in the main, the frame thus
devised will agree with the arrangement introduced from embryo-
logical data. And, again, this series will express the chief features
of the order of succession in which animals were gradually intro-
duced upon our globe. Some examples will show more fully that
this is really the case. Resting more upon the characters derived
from the nervous system, which in the crabs is concentrated into a
few masses, zoologists have generally considered these animals as
higher than the lobsters, in which the nervous ganglia remain more
isolated. Now as far as we know, the embryos of brachyuran Crus-
tacea, that is, of crabs, are all macrural in their shape, that is to
say, they resemble at an early age the lobsters more than their own
parents ; and again, lobster-like Crustacea prevailed in the middle
ages of geological times during the triassic and oolitic periods, that
is, ages before crabs were created, as we find no fossils of that family
before the tertiary period.

Of the class of insects I have for the present little to say, the di-
versity of their metamorphoses having not yet allowed an insight into
their bearing. I will only mention that the predaceous character of
the larvre of most of the sucking insects, which are provided with
powerful jaws in their early stages of growth, seems to indicate that
the chewing insects rank lower than the sucking tribes. Investiga-
tions which I am tracing at present, will, I hope, throw some light
upon this most important question.*

* Since the above remarks were written, I have devoted most of my time to the in
vestigation of these metamorphoses in insects ; and to my great satisfaction (but, I
may say, as I anticipated,) I find that the metamorphoses of the higher insects throw
such light upon the real relations of the different orders of that class, as to settle final-
ly the question of their gradation. It has now become with me a matter of fact, that
Coleoptera, Orthoptera, Neuroptera and Hymenoptera, rank below Hemiptera, Diptera
and Lepidoptera. A careful investigation of the changes of Lepidoptera has shown to
me that, prior to assuming its pupa form, the young butterfly assumes, under the last

198 LAKE SUPERIOR.

In the department of Mollusca, if the above principles are correct,
embryology is likely to introduce modifications in our systematic
methods, which will entirely overthrow the views entertained at pres-
ent respecting their systematical arrangement ; not that we should
ever be led to consider Acephala as higher than the Gasteropoda, or
these as higher than the Cephalopoda ; but within these classes, taken
by themselves, I look for considerable changes, which, when once
introduced, might explain why there is apparently so little agree-
ment between the geological succession of their types and their
systematic arrangement, especially among Gasteropoda. Now it is
precisely among these, that I anticipate the greatest changes. It is
indeed a remarkable fact, that so many, if not all naked branchiferous
Gasteropoda should be provided with a shell in their early age, and
lose this protecting envelop as they grow older, which would lead
to the conclusion, that among these animals the fact of having a
shell indicates a rather lower condition. The comparison of Octo-
pus, Loligo, Sepia and Nautilus would lead to similar conclusions.
Indeed it is scarcely any longer doubted, that Nautilus has many
points of resemblance in common with the Gasteropoda, and from its
numerous tentacles (multiplication being always an indication of a
lower degree,) must be considered the lowest type among Cephalo-
poda ; next we should place the Dibranchiate Cephalopoda, among
which the Argonauta, with its external shell, ranks the lowest ; next
the naked Octopodidoe, while the Sepiadse with their ten tentacles and
internal shell or bone would be the highest in that class. Now if this
arrangement be the real order of succession of the Cephalopoda accord-
skin of the caterpillar, (in which state the caterpillar is so seldom examined, from fear
of disturbing it in its transformation) that under this last skin of the caterpillar, I say,
the young butterfly assumes the characters of a Coleopteron. It has then an upper pair of
wings, having the character of elytra, and a lower pair of membranous wings. At that
time its jaws have not yet assumed the form of a sucker, and are still free, as are also
the legs. But these parts, which are easily observed in caterpillaA immersed in diluted
alcohol at the very moment when they are casting their last skin, are soon soldered
together to form the hard coating of the pupa, and are cast off before the perfect butter-
fly comes out. It is, therefore, correct to say, that the structural condition of Coleoptera,
in their perfect state, answers to that stage of moulting of Lepidoptera which precedes
their perfect development. Coleoptera are, therefore, one stage behind Lepidoptera ;
they rank below them ; they are an inferior degree of development of the type of
insects.

CLASSIFICATION OF ANIMALS. 199

ing to their structure and development, is it not remarkable, does it
not indicate the maintenance of the same plan throughout the crea-
tion, when we find chambered shells, so abundant throughout the
ancient geological formations, and belemnites. the analogues of the
cuttle-fish, beginning late in the secondary epoch in the lias ; whilst
fossil argonauts do not occur before the tertiary times ? So that
we might almost conclude, that in this class the order of succession
of their fossil types is a safer guide for our classification, than ana-
tomical investigation.

In the class of Acephala the low position of brachiopods in the
order of appearance in time, as well as in our estimation of their
structural standing, is another striking instance of the correspondence
between the order of geological succession and the gradation in struc-
ture. I may add as a link for farther inference, that I have seen
embryonic cyclas attached by a byssus to the gills of the mother.

There is perhaps no department in which we may expect more
important results for methodical arrangement from embryological
researches than that of the Radiata. Let us only consider the met-
amorphosis of the Medusae, their first polyp-like condition, their
division and the final transformation of their stem into several distinct
individuals, exemplifying in a higher sphere the growth of compound
Polypi, where the successive buds remain united upon a common
stock. Let us remember the free Comatula growing from the egg
upon a Crinoid-like stem ; let us then remember, that there are ani-
mals of that class, which preserve throughout life this articulated
support, and remind us of corals even in the highest class of Radiata ;
let us farther know, that even the arrangement of plates in those
Crinoids agree in some respects with the first formed calcareous
granules in free moving starfishes ; let us finally and above all here
remember, that those Crinoids with stems are only Echinoderms of
earlier ages, which die out gradually, to be replaced by new and free
forms, and there will not be the slightest doubt left in our minds, that
besides the structure, there is no safer guide to the understanding of
the plan of the creation of the animal kingdom, as it has been in
former ages and as it is in our days, than embryological and palseon-
tological researches.

The internal arrangement of these classes as I now conceive it, would

200 LAKE SUPERIOR.

require that we introduce Bryozoa among Acephala and place them
lowest in that class, next the compound and simple Ascidige, and then
the Brachiopoda and true Acephala. Among Gasteropoda I would
introduce Foraminifera as their lowest type, exemplifying, in a perma-
nent condition, the embryonic division of their germ, next the Ptero-
poda would follow, also as an embryonic form of Gasteropoda, in
which the lateral fin-like appendages and the symmetrical shell remind
us of the deciduous shell of naked Gasteropoda with their vibrating
wheels, and next the Heterobranchia, the common branchiferous Gas-
teropoda, and uppermost the Pulmonata, in some of which the embryo
is not even aquatic, nor provided with fringed appendages. As for
the Cephalopoda, I have recently had sufficient evidence from em-
bryonic investigations that the Octocera stand below Decacera.

GENERAL REMARKS UPON THE COLEOPTERA OF LAKE

SUPERIOR.

BY JOHN L. LEGONTE, M. D.

THE materials which form the basis of the present catalogue, were
not altogether derived from explorations made during the expedition
which produced this volume. They embrace the results of my col-
lections during three journeys made to Lake Superior, and were
procured at various points around the entire circumference of that
sheet of water, and during various months from June to October.

The distribution of species does not appear to differ materially on
the two sides of the lake ; nevertheless many species occurred on
the north shore, which were not found on Point Kewenaw, while
many water beetles were taken at the last mentioned place, which
were not seen during the present voyage. Still in each case the
delay at particular localities was so short, that necessarily many
even of the most common species would be overlooked. We may
therefore conclude, that although the evidence is not yet sufficient to
enable us precisely to distinguish between the products of the differ-
ent portions of the Lake Superior region, we still have abundant
material to give a tolerably complete conspectus of the character of
the entire coleopterous fauna.

The whole country being still almost in a primitive condition, the
specimens are equally distributed throughout a large space : the
woods will not therefore be found very productive to the collector.
In fact nearly all the species were found adjacent to small streams ;
or else they were driven on shore, particularly on sand beaches, by
the winds and waves after being drowned in the lake. So produc-
tive was the last method of collecting, that on one occasion more

14

than three hundred specimens of Coleoptera, and many insects of
other orders were procured in less than one hour.

There are, however, a few points to which the attention of the
future explorer may be directed, as being most likely to reward him
for his arduous journey ; these are Eagle Harbor on Point Kewe-
naw, the Hon. Hudson Bay Co.'s fort at the mouth of Pic River, and
the islands adjacent to the mouth of Black Bay.

For the sake of making the catalogue as concise as possible, I
have used such abbreviations as will render necessary a list of the
works cited. Where no authority is appended to a name, it is to be
understood that the name is used for the first time in this book.
Rarely two references are placed after a name ; in this case the latter
citation is the more recent, and will be found to give all necessary
information respecting synonyms, which are accordingly omitted
here.

rufo-testaceis. Long. '4 unc. In sandy places. This species approaches very near to
the Rocky Mountain one, which I have considered as cribricollis (Dej.), but the head
and thorax are still more coarsely and densely punctured, and the latter more narrowed
behind ; the elytra are obliquely truncate, in some specimens they are rufous at base,
but have no distinct humeral spot, the interstices are flatter, with smaller and more
numerous punctures.

3 By an error of spelling, I formerly wrote Aplochile.

4 D. apicalis. — Subelongatus, nigro-ccneus nitidus, clypeo bidentato, fronte angulatim
leviter impressa, thorace ovali, latitudine fere longiore, antice vix angustato, elytris
thorace parum latioribus, lateribus vix rotundatis, stria marginali ad humerum abbrevi-
ata, tenuiter striatis, striis ante medium punctatis, 211<Ja 7ma 8va que ad apicem exaratis,
interstitiis planis 3'° tripunctato, antennarum basi palpisque piceis, vel rufo-piceis.
Long. -12 unc. The anterior tibia; have the outer spine scarcely longer than the inner,
and but slightly curved, on the outer edge is a distinct tooth, and above it two other
very obsolete denticles.

5 D. seneolus. — -SSneus, elytris nitidissimis, clypeo valde bidentato, fronte transversim
profunde impressa, thorace subgloboso, antice non angustato, lateribus antice leviter
rotundatis ; elytris fere parallelis, apice rotundatis, striato-punctatis, punctis pone
medium extemeque obliteratis, stria sutur aliapice distincta, duabusque aliis (exteriore
longiore) brevibus exaratis, marginali ad humerum desinente, interstitio 3io tripunc-
tato. Long. -15 unc. Two specimens. The terminal spines of the anterior tibiae sub-
equal, scarcely curved ; the outer edge with two denticles, the superior scarcely visible.

6 D. parvus. — This species is only half the size of D. globulosus, but like it has a
transverse thorax, narrowed in front. The clypeus is less deeply emarginate, the frontal
sulcus not so deep, the elytral stria; and points deeper : the internal terminal spine of
anterior tibiee only one half the length of the outer one ; the external margin has but
one denticle. Long. '09.

7 D. longulus. — This differs from D. globulosus, in having the thorax subglobose,
(the length being equal to the breadth,) not narrowed in front; the elytra are more
elongate, the strios are deeper, and can be traced to the apex, although the points vanish
at the middle. The 3rd interstice is 3-punctate, the 8th stria profound at apex ; antenna
fuscous at apex ; internal spine of anterior tibia; 3-4 as long as the outer one, on the
bxiter margin, the lower denticle acute, the upper one obsolete. Long. -11.

8 Erichson calls this group Anchomenus, and adds as a reason that Platyna (Wiedemau
1825) is a genus of Diptera. Before that time the three Bonellian genera were consid-
ered distinct, and therefore the name was not vacant ; Brulle having been the first to
unite these genera, had an unquestionable right to select either of the three names for
the group. Moreover the name Platynus is suitable for the great majority of the
species, and the day has long gone by in science, when a generic name may be changed
because its meaning does not accord with the characters of all the species denoted by it.

9 P. atratus. — Niger nitidus, thorace rotundato, latitudine vix breviore, antice sub-
angustato, basi utrinque late foveato, margine depresso, versus basin anguste reflexo,
angulis posticis nullis ; impress, basalibus brevibus distinctis ; impress, transv. poste-

Long. -34. Very much like P. melanarius (Ag. melan. Dej.) but distinguished by the
smooth basal fovese and less reflexed margin. The ely tral stria? are smooth in one spec-
imen, obsoletely punctured in the other.

P. carbo. — Niger, nitidus, thorace rotundato, latitudine paulo breviore, basi vix ro-
tundato, angulis posticis valde obtusis, rotundatis, basi utrinque late foveato, margine
depresso versus basin angustissime reflexo; imp. trans, posteriore profunda, basalibus
minutis in foveis sitis ; elytris thorace latioribus, tenue striatis, interstitiis planis, 3'°

fovea? deeper and more defined, the reflexed margin narrower and the margin itself
thickened. The base of antennae and palpi have no tendency to become ferruginous.

Varies with the 3rd elytral interstice 3-punctate. Twice the size of P. lenis, and dis-
tinguished by the thorax narrowed behind, basal impressions indistinct, the reflexed
margin broader. P. retractus is much smaller, with a wider thorax and deeper basal
impressions.

11 Under this name, following the example of Erichson, I have grouped all the Ameri-
can species of Dejean's Feronia, excepting the Poecilus, which are sufficiently distinct
by the antenna?. In my catalogue of the Carabica, I admitted as distinct genera nearly
all the groups proposed by other authors, and attempted to find natural characters for
them. What success I have had in finding structural differences, the reader may be
able to judge by referring to the work cited : suffice it to say, that the characters there-
in detailed are entirely too finely drawn for any practical purpose, and by the progres-
sive variation which accompanies the variations of form and sculpture, plainly indicate
the existence of one extensive and natural genus : and fortified as I am by the example
of Erichson, and the counsel of Zimmerman, I hesitate no longer to merge them into
one group, under the name quoted above. An attempt has been made to separate
under the name Hypherpes (Chaudoir) all the species without elytral punctures. But the
characters of this group will be found as ill-defined as those which have just been sup-
pressed. Feronia lachrymosa (Nm.) can scarcely be told from adoxa but by the superior
size, and the presence of elytral punctures ; surely it would be the destruction of all
natural classification, to separate into different genera, two such closely allied species.

12 I have had no opportunity of comparing with European specimens, and give the
species as identical on the authority of Kirby and Klug, having in my cabinet an Oregon
specimen, which has been actually examined by the latter gentleman. Dr. Zimmer-
man thinks it to be different, and proposes the name septentrionalis, which must there-
fore be adopted if the species prove distinct.

posticis rectis prominulis, basi utriuque profunde impresso, bistriato, punctatoque :
elytris tenue striato-punctatis, interstitio 3'° 3-punctato ; palpis pedibusque rufo-piceis.
Long. -32, lat. -14. Readily known by its narrow form : the head is constricted and
punctured behind the eyes : the elytral stria; are fainter towards the apex, which is not
at all sinuate.

14 I have merged into Amara the group Celia (Zim.), as it differs from the typical
species neither in habitus nor characters, the sole ground for separation being a sexual
character of slight import. I have also replaced in the genus, Zabrus avidus (Say) as
it has not the characters of Bradytus, (to which I formerly referred it), the tibia? being
alike in both sexes.

15 I have a specimen which agrees perfectly with Dejean's description, but the thorax
is more narrowed behind than in the figure (Icon. Col. Eur. 3, pi. 170, fig. 2.) No
opportunity for direct comparison has yet occurred. The species is totally distinct
from the two described by me in the 4th vol. of the Annals of the Lyceum.

Kakabeka — Dr. Stout. At first sight seems to be a faded specimen of C. sylvosus
(Say), but the thorax is very rugous, the sides more narrowly reflexed, and the basal
angles much more produced. The sculpture of the elytra is similar, but more distinct.
It is more closely allied to C. taedatus (Fabr.), from Oregon, but the head is less im-
pressed, and the elytra less deeply foveate, with the sides regularly but slightly round-
ed, not straight and narrowed anteriorly as in C. toedatus. Anything that I can say in
praise of the philosopher and gentleman after whom it is named would be quite super-
fluous.

21 N. moesta. — Depressiuscula nigra nitida, thorace latitudine duplo fere breviore la-
teribus marginato, valde rotundato, postice valde angustato, constrictoque, angulis pos-
ticis rectis, antice posticeque transversim profunde impresso, punctatoque, impress,

This maybe Kirby's Helobia castanipes (which I incorrectly cited as N. pallipes Say),
as Dr. Schaum writes me it is very like N. Gyllenhalii, to which our insect has the
closest resemblance. My specimens have not the striae between the eyes mentioned by
Kirby, nor are the feet castaneous : the margin of the thorax is sometimes obsoletely
punctured.

22 N. suturalis. — Elongata depressa, nigra, thorace latitudine fere duplo breviore, lateri-
bus marginato, margine postice latiore, rotundatoque, basi angustato non constricto, an-
gulis posticis obtusis, basi truncato, cum margine obsolete punctato, antice posticeque
profunde transversim impresso, elytris elongatis thorace latioribus obscure runs, sutura
nigricante, striis leviter punctatis interstitiis fere planis, 3io 5-punctato, antennis tibiis
tarsisque rufo-piceis vel runs. Long. -44.

The 8th stria is less deep than the others, but not obliterated ; the punctures in the
marginal series are more numerous than in the preceding. Found on the islands at
the mouth of Black Bay.

3 E. politus. — Obscure ameus, politus, capite sparsim punctato, vertice foveato, occi-

Sault ; common. Punctuation much finer and more dense than in E. ruscarius (Say).
The anterior levigated space is quadrate and extends to the suture : the sides of the
abdomen are so finely punctured as to appear granulate.

25 E. sinuatus. — Laete viridi-tcneus, supra et subtus confertissime subtiliter punctatus,

Long. -31, lat. -13. Pic; two specimens. Narrower than the preceding, the punctures
of the side of the abdomen are more distinct ; but still the pectora are more closely
punctured than in E. ruscarius.

Size of N. porrectus ; but the striae are more densely punctured, less obliterated, and
the feet and antennae black. It resembles much N. confusus Lee. (semistriatus Say,
teste Harris), but the 1st stria is not curved and exarate at tip, the base of the anten-
nae less decidedly pale, and the scutellar stria is not double.

Karainistiquia River below Kakabeka Falls. This species is very similar to O. purpu-
rascens Lee., but the basal impression of the thorax is single, and less profound ; the
stricc of the elytra are less punctured ; the 8th and 9th strise are obliterated.

11 H. longulus. — Elongato-ovalis, rufus, capite thoraceque punctatis, hoc striola

Narrower than the others ; outline regularly oval : tip of elytra more obliquely
sinuate than in H. americanus, but scarcely truncate. The points of the thorax are
more distant immediately behind the middle of the disc ; the thorax is slightly infuscat-
ed at the apex. Varies without any elytral spots.

31 0. axillaris. — Nigro-seneus, pernitidus, thorace convexo, valde cordato, antice vix

One half larger than H. americanus, and easily known by the want of the basal striola
of the thorax ; the base of the elytra is blackened along the edge : the spots placed as
in H. americanus.

Head finely punctured, with a smooth vertical space. Elytra slightly, but not suddenly
dilated behind the thorax, then regularly narrowed to the tip, which is obliquely trun-
cate and acuminate : the disc is marked with two spots at the anterior third placed
obliquely forward and outwards, just behind the middle 2 or 3 nearly transversely, and
2 or 3 more obliquely backwards and outwards at the posterior fourth. Varies, with the
posterior spots wanting. St. Ignace.

33 H. cribrarius. — Ovalis convexus, pallide testaceus, capite postice, thorace antice

uniseriatim punctatis, sutura angustissime, apice guttisque 6 vel 7 parvis nigris.
Long. -17.

Very similar to the preceding, but the points above and beneath are larger. The
elytra are less attenuated behind the dilated part, the sides being nearly parallel.

34 I found the elytra of a ? , and have seen perfect specimens from Lake Huron.
It is smaller than D. Harrisii, the oblique yellow band at the tip of the elytra is very
distinct, the sulci terminate at \ from the apex, and are not confluent. In the latter
species the 9 has smooth elytra.

35 D. diffinis. — Elongato-ellipticus antice vix angustatus, supra nigro-olivaceus

Eagle Harbor. Mr. Rathvon. Form of confluens, but only one half the size. The
sides of the thorax scarcely rounded, the posterior yellow margin scarcely wider in the
middle than at the angles.

36 Varies with the posterior margin of the thorax, narrowly testaceous.

37 This species is more narrowed anteriorly than its European analogue, and wants
the narrow rufous line at the base of the thorax ; moreover the $ has the external basal
portion of the elytra more densely and distinctly punctulate.

38 I know not whether Dr. Harris' name is published. In case it is, Aube's C. binota-
tus (p. 247, a "West Indian species) must fall. I have the less hesitation in giving our
species as identical with the Mexican C. maculicollis, as I found at the Rocky Mountains
numerous specimens, which do not differ from those obtained at the north. Mr. Melly,
from actual comparison, also informs me that it is identical.

38 I. pleuriticus. — Angustior oblongo-ovalis convexus, postice suboblique attenuatus,
supra aeneus, minute reticulatus opacus, capite in vertice binotato, anticeque rufo, elytris
pone basin vix dilatatis subparallelis, pone medium gutta oblonga, alteraque versus
apicem pallidis, epipleuris pedibusque piceis, vel rufo-piceis. Long. lat.

Narrower than I. biguttulus, less dilated behind, the sides of the elytra being almost
parallel for nearly | of their length, then gradually attenuated to the apex ; the irregu-
lar series of points are more distinct behind the middle.

I. picipes : "What I consider as this species is much smaller, narrower and less convex
than I. biguttulus, the thorax less abbreviate, somewhat rounded on the sides ; elytra
nearly parallel, and less suddenly attenuated at the tip ; the confused rows of points
are more distinct. My specimen is immature, and the body is rufo-piceous.

40 A. angustus. — Depressus, anguste ovalis, postice suboblique attenuatus, niger
subopacus, capite subtiliter, thorace elytrisque grossiusreticulatis,illo uiargine anguste
depresso, lateribus ante medium rotundatis, angulis posticis acutis subproductis, ore
antennis, palporumque basi ferrugineis. Long. lat.

Very distinct from its large size and peculiarly shaped thorax. The rows of impress-
ed points on the elytra are distinct, and the reticulations become finer at the apex
and margin.

41 A. parallelus. — $ $> Elongato-ellipticus depressus, niger nitidus subtilissime retic-
ulato-strigosus, capite antice vix ferrugineo, antennis palpisque ferrugineis. Long. -38,
lat. -2.

Differs from A. striatus in being more elliptical, the two ends being similarly rounded,
and the elytra quite parallel for the greater part of their length ; the head is wider and
the thorax less narrowed in front. The reticulations are a little more evident than in
that species.

The interrupted lines have not a tendency to coalesce into fasciae, as in H. pubipen-
nis (Aubf1), from which it is easily known by the longer pubescence and finer punctua-
tion ; the body is less attenuated behind, and a little more convex. The thorax is
much more narrowly margined, and, when viewed sideways, forms a very slight angle
with the margin of the elytra.

in some specimens, besides the basal spots there is an oblique black line towards the
margin. The 3rd and 5th elytral lines alone attain the base ; at the tip they are gradu-
ally shorter externally, and the 4*, o'h, and 6th are united. Seems allied to H. frater
Steph. (Conf. Aube, 528). Were it not for the obsolete punctures and yellow head, it
would be H. lcevis, Kirby, N. Z., 68.

45 I must give Kirby's species as distinct, although Dr. Schaum tells me their Euro-
pean analogues are considered identical, lineellus being a $ variety of picipes. I have
both $ ? of our species, each agreeing with its opposite sex in sculpture, and differ-
ing only in lustre, the $ being shining, the ? opaque.

Resembles H. americanus, but is darker colored, and less convex ; the punctuation
of the thorax is less distinct in the middle, that of the elytra less dense ; there are
traces of a stria J way between the suture and margin.

Resembles the two next, but is narrower, a little more convex, the posterior angles of
the thorax are somewhat obtuse, and the sides form an angle with the elytra.

At first sight seems to be a variety of the preceding. It is less convex and less nar-
rowed in front. The points of the elytra at the base are unequal, but at the apex
they become more dense and equal.

Some of the scattered punctures at the base of the elytra have a tendency to form
three distant longitudinal bands, the first being near the suture.

though it was safely secured in a bottle, it was not there by the time I reached camp.
I therefore forbear naming it, merely directing the attention of future explorers to this
very interesting species.

Head large, semicircularly rounded anteriorly, acutely angulated on the sides behind,

not emarginate in front, base rounded, angles none. Elytra covering the abdomen,
declivous, scarcely convex behind. Palpi filiform. I should have considered this insect
a Cybocephalus, but for the filiform tarsi. The structure of the antennae differs from
Cyllidium, but I am by no means certain that I have placed it in a proper position : it

posterior coxae prevents a complete examination of the lower surface.

91 A. hyperboreus. — Oblongus rufo-piceus nitidus, capite nigro, thorace lateribus
punctate, disco lasvissimo, angulis posticis obtusis rotundatis, basi vis marginata
utrinque obliqua, nigro lateribus obsolete rufis, elytris crenato-striatis, interstitiis fere
planis, luevissimis. Long. -3. Pic. The clypeus is smooth, with only a few points at
the side, the margin reflexed, and slightly emarginate. Belongs to Erichson's di-
vision D, as well as the three following species. It is very similar to A. omissus, but dis-
tinguished (apart from color) by the smooth clypeus and impunctured elytra. I have
changed the name of the next species, as it cannot be Mr. Say's A. concavus : that author
makes no mention of the large scutellum, which he would not have failed to observe in
comparison with other species. I know not how Mr. Haldeman omitted this character
which would serve at once to distinguish the species in question, and A. pinguis from all
the other American species seen by him.

92 A. angularis. — Oblongus niger nitidus supra undique sparse subtiliter punctulatus,
thorace lateribus rotundato, angulis posticis obtusis non rotundatis, basi vix marginata,
utrinque oblique vix sinuata, lateribus punctatis, disco parce punctato, elytris profundius
crenato-striatis. Long. -26. Pic. Variat elytris piceis, pedibus rufo-piceis.

Agrees with A. pinguis in being covered with a fine punctuation ; the clypeus is more
broadly emarginate, and the posterior angles of the thorax not at all rounded ; the basal
margin of the thorax is interrupted and indistinct. The $ has the thorax a little
wider than the elytra. Belongs also to Erichson's division D.

13 A. consentaneus. — Elongatus, rufo-testaeeus, elytris pallidioribus, capite thora-
ceque subtiliter sat dense punctatis, hoc lateribus parum rotundato angulis posticis ob-
tusis valde rotundatis, basi tenuiter marginata, elytris thorace non latioribus profunde
crenato-striatis. Long. -2.

Clypeus margined, scarcely emarginate, frontal suture straight : the punctures of the
thorax are intermixed with a few very minute points. Belongs to division E, of Erich-
son.

94 R. cribrosus. — Piceus, opacus, thorace lateribus rectis, angulis posticis late emar-
ginatis, basi vix rotundata, grosse confertim cribrato, canaliculate, elytris antice suban-
gustatis, basi emarginatis, acute 10-costatis, sulcis uniseriatim leviter punctatis. Long.
•16.

Head convex, punctured, clypeus scarcely margined, oblique each side. I should
refer this species to Euparia, were not the posterior tibiae destitute of the rows of bris-
tles, and the external spur which distinguish that genus ; they have two scarcely dis-
cernible rudiments of teeth on the outer edge. The podex is entirely concealed by the
elytra.

95 M. lacustris. — Oblonga, convexa, postice subdilatata, nigra nitida, thorace trans-
verso, antice angustato, basi marginata, utrinque oblique subsinuata, angulis posticis
rotundatis, lateribus marginatis, anticeque impressis, sat dense grossius punctato,
elytris valde crenato-striatis, interstitiis convexis loevibus. Long. '18.

Head convex, rough anteriorly with elevated granules, clypeus finely margined, widely
emarginate. There are also two species found on the Atlantic coast.

(5 antennarum clava parte reliqua longiore, corpore cylindrico.

This is one of a group of very closely allied species, which I have divided according
to the form and punctuation of the thorax, and the form of the sutural angle of the
elytra. It is the common species everywhere, and is probably Mel. quercina Knoch.

97 L. anxia. — Nigro-castanea nitida, supra glabra, antennis pedibusque rufo-testaceis,
thorace sat dense distinctius punctato, antice angustato, lateribus parum dilatatis,
angulis posticis rectis, basi media late minus extensa, elytris leviter 3-costatis distinct-
ius sat dense puuctatis, umbone humerali prominulo, angulo suturali obtuso, pygidio
parce punctato, basi longitudinaliter rugoso. Long. -92.

? Corpore postice modice dilatato. More dilated behind than the preceding, with
larger punctures on the thorax and elytra.

98 L. consimilis. --Postice nondilatata, castanea, nitida supra glabra, antennis pedibusque
testaceis thorace subtilius parce punctato, antice angustato, lateribus modice dilatatis,

isque, angulo suturali valde obtuso, pygidio parce punctato, basisubruguloso. Long. '93.

$ clava antennarum parte reliqua vix longiore.

Differs from the large eastern species (Mel. brunnea Kn.) in having the thorax less
dilated on the sides, the posterior angles not acute, and the sutural angle of the elytra
very obtuse.

99 L. futilis. — Dilute castanea supra glabra nitida, antennis testaceis, thorace sat
dense minus subtiliter punctato, latitudine triplo breviore, antice angustato, lateribus

Eagle Harbor, Mr. Rathvon. Very similar in appearance to S. buprestoides, but the
form of the thorax is different. The posterior tibiae are scarcely dilated at the end.

31 C. gibbulus. — Niger pubescens, thorace oblongo, modice elevato, confertissime
punctato, elytris confertim subtiliter pimctatis, basi subgibbosis, gibberis minus eleva-
tis, ante medium rufis, lineis 2 obliquis apiceque densius cinereo-villosis : antennarum
articulo lmo tarsisque rufis. Long. -27.

Very similar to C. verrucosus, but the thorax is less elevated and the elytra more
distinctly punctured and much less gibbous : the 3rd joint of the antennae is not arm-
ed with a spine : in the markings there is no difference, except that the cinereous lines
are less oblique.

32 JE. despectus. — Niger cinereo-pubescens, supra punctis pluribus nigro-pubescenti-
bus variegatus, thorace transverse laevi, basi abrupte constricto, serieque transversa,
punctorum notato ; elytris apice truncatis macula oblonga sublaterali versus medium
fasciaque angulata pone medium nigris. Long. '41.

The antennae and posterior tibiae are annulated, the former in both sexes but little
longer than the body : the femora have one or two black spots. It is found everywhere ;
the <j? has the anal segment elongate and truncate.

33 P. penicillatus. — Cylindricus, niger dense cinereo-pubescens, thorace lateribus
spinoso, disco valde tuberculato, calloque parvo pone medium elevato, confertissime
punctulato, elytris apice truncatis, cinereo, fuscoque variegatis, fascia lata ante medium
albida ; 3-carinatis, carina 1 ma pilis longis nigris fasciculata, interstitiis minus dense
punctatis. Long. -27. Pic. The antennae and feet are annulate.

I am doubtful if the next species (Tetraopes) is found at Lake Superior.

34 S. adspersa. — Nigra, ochraceo dense pubescens, thorace latitudine sesquibrevi-
ore, grossius ocellatim punctato, punctis nigris ; spatio utrinque fere ad apicem ex-
tendente minus dense pubescente ; elytris postice subangustatis, sutura acuminata,
sparsim grosse nigro-punctatis, hue illuc spatiis densius pubescentibus, quorum unum
mox pone medium oblique versus suturam ascendit. Long -9.

Very close to S. calcarata, but the color differs, and the thorax is shorter.

35 S. moesta. — Nigra cinereo-pubescens, grosse confertim punctata, thorace latitu-
dine vix breviore, basi leviter angustato, cinereo-bivittato, elytris apice rotundatis, an-
tennis corpore brevioribus annulatis, basi nigris. Long. -5. Pic.

The claws are entire, although at first view it would seem to be a Phytoecia ; the
head has a black, finely impressed frontal line. The eyes are almost divided.

tatis, punctis antice elevatis ; rufo-piceis, pube cinereo, fuscoque variegatis, antennis
nigris, cinereo annulatis. Long. -98.

This is very similar to M. confusor Kb. (maculosus Hd.), but the thorax, which is
smooth in that species with a few small punctures, is rugosely punctured, and the
suture of the elytra is slightly prolonged. The $ has very long black antennae.

37 ARGALEUS. Caput mox pone oculos non constrictum ore attenuate, palpis labi-
alibus modice dilatatis. Antennae ante oculos insertae, longac ; oculi antice emarginati,
postice truncati. Tibiae posticae apice truncates, calcaribus terminaliter sitis. Thorax
spinosus. Elytra triangularia.

Differs from Toxotus cylindricollis, &c., in the form of the eyes, as well as the situa-
tion of the terminal spurs of the tibiae. The spinous thorax gives an appearance like
Rhagium. To this genus belongs the European Toxotus cursor.

A. nitens. — Minus elongatus, niger subtiliter dense punctatus longe cinereo-pubes-
cens, thorace canaliculato, antice angustato, basi apiceque profunde constricto, lateri-

European P. virginea and collaris.

B. Body more slender, mouth elongated : the species cited above, with 4-vittata.

The 3rd and 4* joints of the antennae are equal, and a little shorter than the 5th.
Varies with the elytra fuscous. I have diligently compared this with European spec-
imens, without finding any difference.

42 ANTHOPHILAX. Caput mox pone oculos constrictum, palpis dilatatis, labialibus
multo latioribus. Antennae 11-articulatse, inter oculos insertae; oculi emarginati.
Thorax angulis posticis rectis, utrinque modice constrictus, lateribua acute tubercu-
latis.

To this group belongs Pachyta 4-maculata of Europe. Differs from S'trangalia and
Leptura by the dilated labial palpi.

A. viridis. — .Nigra, capite thoraceque virescentibus, punctatis, cinereo-pubescenti-
bus, hoc antice angustato, utrinque constricto, leviter canaliculate, lateribus subacute
spinoso, elytris grosse confluenter punctatis, substriatis, splendide viridi-ajneis, apice

The 3rd joint of the antenna? is longer than the 4th.

43 S. plebeja. — Elongata, nigra, confertim punctata, thorace longe flavo-pubescente
lateribus parum rotundatis, utrinque tenuiter profunde constricto, angulis posticis
laminatim productis ; elytris testaceis, postice sensim angustatis, paulo dehiscentibus,
apice intus incisa. Long. -55.

Precisely similar to S. nigrella, except in the color of the elytra: the pubescence of
the thorax is long and prostrate ; while in S. nigrella it is short and erect.

44 L. tibialis. — Nigra, breviter flavo-pubescens, capite thoraceque confertissime
punctatis, hoc convexo, antice parum angustato, apice, basique constricto, lateribus vix
rotundato, elytris confertim punctatis, subparallelis, apice paulo dehiscentibus, intror-
sum oblique leviter truncatis, flavo-testaceis, macula laterali ad medium, altera majore

Plate 8th represents twelve new species of the Coleoptera, de-
scribed in the preceding Catalogue.

On glancing over the catalogue which is just ended, the entomolo-
gist cannot fail to be struck with two very remarkable characters dis-
played by the insect fauna of these northern regions. First, the entire
absence of all those groups which are peculiar to the American
continent. Thus, there is no Dicoelus, no Pasimachus among the
Carabica ; the Brachelytra are represented only by forms common
to both continents. Among the Buprestidss is no Brachys ; in the
Scarabseidre, the American groups (except Dichelonycha) are com-
pletely unrepresented ; in brief, there is scarcely a genus enumerated
which has not its representative in the Old World. The few new
genera which I have ventured to establish, are not to be regarded as
exceptions, they are all closely allied to European forms, and by no
means members of groups exclusively American.

Secondly, the deficiency caused by the disappearance of charac-
teristic forms, is obviated by a large increase of the members of
genera feebly represented in the more temperate regions, and also
by the introduction of many genera heretofore regarded as confin-
ed to the northern part of Europe and Asia. Among these latter
are many species which can be distinguished from their foreign

analogues only by the most careful examination. This parallelism
is sometimes most exact, running not merely through the genera,
but even through the respective species of which they are composed ;
thus of the two species of Olisthgerus, each is most closely related
to its European analogue, 0. laticeps being similar to 0. megace-
phalus, while 0. nitidus can scarcely be known from 0. substriatus.

While upon this subject, we may take occasion to distinguish the
different kinds of replacement of species, which are observed in pass-
ing from one zoological district to another more or less distant.
There appear to be four distinct modifications by which faunas are
characterized.

1st. When the same species, or organic forms, so similar as to pre-
sent no appreciable difference, appear at points so situated as to
preclude the possibility of any intercommunication. These are most
rare, and are only observed when the physical circumstances under
which the species exists are nearly identical.

2cl. When a species in one district is paralleled by another in a
different region so closely allied that upon a superficial glance they
would be regarded as the same. These are called analogous species ;
e. g., the Olisthreri, Spondyli, Bembidia, Helophori, &c., &c., of
the preceding catalogue, as compared with European species.

3d. Where several species in one region are represented by
several others of the same genus, which perform a similar part in
the economy of nature, without, however, displaying any farther
affinity to each other. These are called equivalent species ; e. g.,
most of the species of Cicindela, Brachinus, Clytus, Donacia, &c.,of
America, as compared with those of the eastern world.

4th. Where the members of a group are represented collectively
by kindred species in another district, which however display such
differences of structure that each may at once be referred to its pro-
per locality ; e. g.,most of the Melolonthae among Coleoptera, and
the entire group of Quadrumana among mammalia.

Now it will be observed, that in proceeding from the Arctic circle
to the tropics, the prominent character of the fauna is successively
modified by these peculiarities. We pass from a region where the
fauna is the same at remote points, through one where the produc-
tions are similar, but not identical, to one finally, where the equilib-

REMARKS ON THE COLEOPTERA. 240

rium of forms is still preserved, but where the general arrangement is
totally different, the prominent groups of one continent being either
feebly represented on the other, or else entirely wanting.

It does not become us, in the present imperfect state of tropical
exploration, to determine what groups are peculiar to each continent ;
we can merely say that particular forms are more abundant in certain
regions. For by a strange fatality, (at least in Coleoptera,) no sooner
is any group admitted by a common consent to be exclusively Amer-
ican, than suddenly, as if produced by the well-known jugglery of
those countries, a species starts up in Central Asia, or Africa, (e.g.,
Galerita, Agra, Sandalus.) Still, enough remains to show us that
the prevailing character of tropical fauna is individuality ; the
production of peculiar forms within limited regions : while the dis-
tinguishing feature of temperate and arctic fauna is the repetition of
similar or identical forms through extensive localities.

On proceeding now to illustrate these deductions by special exam-
ples from the catalogue before us, it will be seen that the parallelism
of species in temperate and frigid climates can be demonstrated more
particularly in the genera which are more universally diffused over
the earth, or in those which are especially confined to temperate re-
gions, than in such as receive their principal development within the
tropics. Thus for instance, among the great group of Carnivorous
Coleoptera, the terrestial species, (although well represented in cold
climates,) contain an immense number of genera, each of which
(with few exceptions) seems to have a particular locus, external to
which it is feebly represented. Accordingly in this group, the par-
allelism of species is by no means clear, and the forms are rather to
be considered equivalent than analogous. On the other hand,
among the aquatic Predaceous Coleoptera, the genera are but few,
and the tribe is more abundant in cold regions ; and in these the
parallelism is most exact, so that there are but few mentioned in the
preceding pages, that have not their exact counterparts in Europe.
The characters appended to the new species will render this sufficient-
ly obvious to the student, while the relations of those previously
described by Kirby and Aube have already been clearly pointed out
by those authors.

Passing on to the other water-beetles, the species of Helophorus

240* LAKE SUPERIOR.

and Ochthebius will afford other striking examples of this parallelism.
Among the Brachelytra are numerous other instances, the most re-
markable being the genus Olisthwrus, already alluded to. Protei-
mis and Megarthrus also for the first time appear on this continent.
The Aphodii with large scutellum, the Ditylus, Pytho, Sphreriestes,
and Spondylus are also good illustrations. Among the Elateridse are
numerous instances, but having not yet submitted this group to phi-
losophical study, I have not ventured to describe the new species,
but have merely indicated them by names. For the present there-
fore, any remarks on the parallelism of the forms in this group must
be postponed. Notwithstanding this approximation to a uniform,
subarctic standard, we still find in these boreal regions, a prevailing
character of North American fauna — the extreme paucity of Curcu-
lionidse. The Donacige too, although numerous, do not afford any
prominent parallelism. The American species can only be regarded
as equivalent to the European.

On concluding this short essay on the geographical distribution of
Coleoptera in the northern part of our continent, I feel that some
cause must be assigned for the brief manner in which such extensive
material has been disposed of. Enough has been given to point the
laws of distribution, and to show that they accord most perfectly with
those derived from other branches of natural history, while during
the yet imperfect condition of entomological science in this country,
a minute analysis of the components of the entire fauna would be a
work of immense labor, and would in fact be rendered nugatory,
until all the species are described, and all the groups submitted to a
philosophical revision. My complete success in tracing the par-
allelism between the Pselaphidee of Europe and North America (in
an unpublished monograph of this family) leads me to believe that
a rich store of material is herein presented to such minds as are satis-
fied with statistical comparisons between the inhabitants of different
zoological districts ; and that nothing but industry and a free access
to the most common European insects is required to produce a most
formidable list of analogous species. I shall rest satisfied with having
shown that this parallelism exists even more accurately than in the
vertebrate class, and with having pointed out examples far more
numerous than those furnished by the higher animals : the more so,

REMARKS ON THE COLEOPTERA. 241

since I feel that one already conversant with entomological names
will find no difficulty in extending the already long list of parallel
species, while to the general reader, who desires only the deductions
of science, without entering upon the tedious processes by which
they are obtained, a catalogue of mere technicalities, which fail to
convey a single idea to his mind, will be equally useless and uninter-
esting.

I purposed in the present essay to trace, as far as possible, the
mechanism of the agency by which the present distribution of species
has been effected, and to reduce its most obvious results to some fixed
principles. Fearful, however, lest my views should be considered as
derived exclusively from a consideration of insects, and their phe-
nomena of distribution, I prefer waiting until a sufficient familiarity
with other sciences will enable me to be less partial in my choice of
illustrations. I do this with the less regret as I find some of my
deductions are at variance with many of the most ancient, and most
firmly established prejudices of our nature, and before venturing any
assertion, which even in appearance deviates from " general impres-
sions," it is at least prudent to be supported by facts drawn from
more extended observation than is furnished by one or two limited
departments of knowledge.

In the rapids at Niagara have been observed large numbers of
the singular animal described by Dekay (in the Zoology of New
York) as a new genus of Crustacea, under the name of Fluvicola
Herricki. They were attached to stones just below the surface of
the water, and crawled but slowly ; when seized, they endeavor to
contract themselves into a ball.

These animals have a marvellous resemblance to the extinct group
of Trilobites, although, as will be seen in the sequel, they are the
larvae of an insect. Mr. Agassiz informs me that a similar form has
long been known to the zoologists of Continental Europe as Scutel-
laria amerlandica, but I have not been able to find any .published ac-
count of it.

On turning over some stones near the river bank, I was agreeably
surprised to find many specimens which had left the water for the
purpose of changing into pupge. The elliptical shield of the superior

241* LAKE SUPEEIOR.

surface, which gives the animal its Crustacean appearance, was firm-
ly adherent to the stone by its ciliated margin, and formed an excel-
lent protection under which the later transformations could take
place with safety. In fact, the superior shield being cast off with
the larva skin, served in place of the cocoon or nest constructed by
many larvae, before transforming.

I regret that in the short account given by me at the recent
meeting of naturalists in Cambridge, I was -induced to speak of this
discovery, without having access at the time to specimens. Those
which I expected to find at Boston had been lost, and my former
examination of the pupae collected by myself was very slight. I
referred the insect to the order of Neuroptera, and I must here
return my sincere thanks to my friend Dr. Harris, for a hint towards
its true nature.

For the opportunity of examining some very large and well devel-
oped larvae, I am indebted to my friend I. C. Brevoort, who procured
them at Niagara in July of the previous year.

The body proper of the larvae is elongate, the head being free,
(i. e. not retractile,) but concealed under the large shield, like a pro-
longation of the dorsal epidermis of the prothorax. On each side
are six small, approximate ocelli, anterior to which is the antenna,
a little longer than the head, and two-jointed ; each joint having a
tendency to become divided at its middle, so that on a superficial
inspection there would appear to be four joints. These organs are
inserted at the outer extremity of the clypeo-cranial suture ; the
labrum is large, and a little emarginate in the middle. The lower
part of the head is covered by a large mentum, which prevents the
mandibles and maxillse from being seen. The maxillary palpi are
half the length of the antennae, filiform, rather stout, and three-articu-
lated, the joints being equal. The labial palpi are bent down and
covered by the epidermis. In the very young larvae the palpi are
still shorter in proportion to the antennae. A more full description
of the parts of the mouth must be reserved for a separate treatise,
when their structure can be illustrated by plates. The abdomen is
furnished on each side with six bunches of long branchial filaments,
which proceed from the interstices between the articulations ; there
is a larger bunch of filaments connected with the anal aperture, which

r

REMARKS ON THE COLEOPTERA. 242

may be retracted, and is ordinarily not visible in dead specimens ;
exterior to these filaments on each articulation is a small fovea. The
articulation itself is prolonged each side, for a short distance between
the laminae of the expanded epidermis, so thn t the outline of the proper
fleshy portion is serrate. The legs are slender, the tarsus inarticulate,
and furnished with a single claw.

The pupa is broadly oval, and depressed. The head is concealed
under a hood formed by the prolongation of the epidermis of the
prothorax. This hood is produced at the posterior angles, so that it
becomes exactly similar to the thorax of a Lampyris.

The front between the antennae is transversely elevated, so that
the mouth is situated on its inferior surface. The antennae are three
times longer than the head, and inside of the pupa skin (in much
developed specimens) are seen to be serrate, and eleven-jointed ; the
palpi are two-thirds the length of the antennae, and are somewhat
dilated at the extremity. The labial palpi are very short. The
labrum is transversely cordate. The wings are bent under the body.
The superior ones exhibit the structure of elytra, and have four slight
longitudinal ribs : the inferior are membranous, and show a slight
transverse nervure near the middle. The abdomen is six-jointed and
serrate at the sides, owing to the angular prolongation of each joint,
and is entirely free from branchial appendages. The last joint is
rounded. The feet are slender, and not armed with a claw. The
mesopectus is deeply channeled.

After the description just given of the pupa, no one will doubt
that the insect belongs to the Coleoptera ; and from the serrate out-
line of the abdomen, one would be inclined to refer it to the groups
possessing larvae like the Lampyris, Lycus, &c. The separation of
the prothorax and its great development, as well as the structure of
the superior wings, absolutely exclude it from the Neuroptera, to
which I at first referred it.

The peculiar structure of the head of the pupa, and the great
length of the palpi, point clearly to Eurypalpus, a curious genus,
which is placed by authors near Cyphon, which, as is well known, is
closely allied to the Lampyridae. Eurypalpus differs very much from
all the allied genera, in being aquatic. It is furnished with slender
legs, but the tarsi are long, especially the last joint, which has two

242* LAKE SUPERIOR.

very strong claws, (as in Macronychus) to fit it for clinging to stones
in a rapid current. The mesopectus of Eurypalpus is likewise deeply
channeled. The elytra are also furnished with three or four very
obtuse elevated lines. As yet there is but a single species of the
genus known. E. Lecontei, (Dej. Cat.) I am not aware that any
description has been published of it.

Thus is settled the history of the transformations of an anomalous
form, which has much perplexed naturalists for many years. Its
history shows the care with which our investigation should be made,
when we are upon unknown ground. But where the homologies of
the animal with other aquatic larvae provided with branchia are so
exact, it is a little remarkable that its larval character should remain
so long unnoticed. The only difference between it and an ordinary
larva (either of Coleoptera or Neuroptera) is the prolongation of
the dorsal epidermis, to form a shield under which the true body is
concealed. Similar prolongations are found in nearly all orders of
insects.

I know not how Dr. Dekay fell into the mistake of considering
the elongate palpi as a second pair of antennae : and surely such an
anomalous form as a Crustacean with six legs, and a head separate
from the thorax, deserved a more careful examination, before receiv-
ing a definite place in the system.

The figure in the New York Zoology, (as the animal is very pecu-
liar in its form,) bears a certain vague resemblance to what it was
intended to represent ; but for all systematic purposes, it is, like
nearly all the plates in that part of the State Survey, perfectly
worthless.

made a critical comparison of our Vitrina with the V. pelludda of Europe, with which
species it has hitherto been regarded as identical, I am induced to believe that they are
different species. The American shell is more globose ; the plane of the aperture is
more oblique, and the basal portion of the lip sweeps round from the columella in a
rapidly curving arc, instead of stretching off almost horizontally ; indeed the whole
aperture is more nearly circular. These differences become quite obvious when the
shell is greatly magnified. The color of the European shell is always more or less
green or yellow, whereas the American specimens are colorless, and decidedly more
fragile. In size, they are about one fourth smaller than the foreign ones, and have, at
least, half a whorl less in the spire. It is indeed more nearly like V. subr/tobosa, Mich,
which, however, has a much more elevated spire, and its basal face much more inflated.

I quote the above description of a species first brought from Lake Superior by Dr.
C. T. Jackson, and hitherto found only in the region of that lake. Prof. A. found it on
the north shore, at Michipicotin. It is well characterized by its inflated form, delicate
structure, striated surface, its wine-red color externally, and its liver-brown color within.
It resembles, somewhat, P. ancillaria, which differs in form by having shouldered
whorls, and its greatest diameter behind the middle. Unfortunately, the figure has
been drawn from a very small specimen, and does not exhibit the characters of a full-
grown specimen. (See pi. 7, figs. 10 and 11.)

3 LIMNEA CATASCOPIUM. There is no slight difficulty in defining the limits of allied
species in this genus. While real specific characters are very few and ill defined, the
variations of species are very numerous and wide in their range ; nevertheless, by a
certain facies, or by collecting large numbers at a given locality, we are able to pro-
nounce shells which are very different in their aspect to be specifically identical.
These remarks apply with special force to the species above named. Some of the
specimens are elongated and slender, while others are short and ventricose ; some are
thin and fragile, others dense and firm ; some are smooth or with a delicately cor-
rugated epidermis, others are indented and broken into numerous facets ; some have a
very largely developed fold on the pillar, while others present a simple column ; in
some the columella is curved and flexuous, in others it is direct ; some have regular
and symmetrical outlines made up of cylindrical whorls, while others have a very acute
angle and a broad shoulder at the posterior part of the body whorl ; and the color may
be amber, brownish, livid or cinereous. There can be little doubt that these wide va-
riations have been regarded as different species, as indeed they could not fail to be,
were only isolated specimens examined ; but when we come to compare large numbers
collected in company, we see the connecting links and the necessity of retaining them
under one name. Among them we find L. pinguis, Say, which Mr. Haldeman has al-
ready referred to this species ; and also L. emarginata, Say, which, from the few speci-
mens he had seen, Mr. Haldeman deemed to be a well marked species. The numerous
specimens since brought from the Lake Superior region render it sufficiently certain
that it is only a variety of L. castascopium, with the last whorl more or less angular
posteriorly, and with a straight pillar which gives to the base of the aperture a pecu-
liarly broad and distorted form.

Amid all the variations, however, there is a certain aspect of the aperture which is
characteristic. It is large when compared with that of L. wmbrosa, or L. elodes ; it is near-
ly semicircular, while in large specimens of L. desidiosa, where the proportional size of
the aperture is more nearly the same, its posterior outline is broad and nearly transverse.

The number of bivalve shells seems to diminish very abruptly at the chain of
the great lakes; so that of the great number of species, so profuse also in the
number of individuals, in the States bordering on the south, scarcely ten spe-
cies, and those not abundant, are found to the north ; and all these are meagre
in development, and of the simplest form and color.

A medium sized species, with an elongated, delicate, minutely reticulated shell, com-
posed of about six very oblique flatfish whorls, the last of which constitutes three fourths
of the whole shell. The aperture is narrow, having a sharp, slightly winding fold on
the pillar, and a submarginal brown stripe just within the lip.

Next to L. gracilis, this is the most delicate species we have. It may be compared
with L. attenuata and L. reflexa, from both of which it differs in the flatness of its
whorls, in its narrow, elongated aperture, and in being only half their size. It is much
like Physa hypnorum reversed.

5 PISIDIUM DUBIUM. The separation from Cyclas of some species under the name of
Pisidium being regarded as legitimate, I place this shell under that genus. The shells
brought from Lake Superior seem, however, to differ somewhat from specimens from
the Atlantic region. They are smaller, more elevated, less sulcated, and the hinge is
less robust. I had designed to apply to them the specific name P. tenellwn, but un-
fortunately the specimens were mislaid before I had examined them with sufficient
care to give the characters with the requisite precision.

FISHES OF LAKE SUPERIOR COMPARED WITH THOSE OF
THE OTHER GREAT CANADIAN LAKES.

BESIDES the interest there is everywhere in studying the living
animals of a new country, there is a particular interest to a natural-
ist in ascertaining their peculiar geographical distribution, and their
true affinities with those of other countries. It is only by following
such a course, that we can hope to arrive at any exact results as to
their origin. In this respect the freshwater animals have a peculiar
interest, as from the element they inhabit, they are placed under
exceptional circumstances.

Marine animals, as well as those inhabiting dry land, seem to have
a boundless opportunity before them to spread over large parts of the
earth's surface, and their locomotive powers would generally be suf-
ficient to carry them almost anywhere ; but they do not avail them-
selves of the possibility ; notwithstanding their facilities for locomo-
tion, they for the most part remain within very narrow limits, using
their liberty rather to keep within certain definite bounds. This
tendency of the higher animals especially, to keep within well-ascer-
tained limits, is perhaps the strongest evidence that there is a natural
connection between the external world, and the organized beings

' O O

living upon the present surface of our globe. The laws which regu-
late these relations, and those of geographical distribution in partic-
ular, have already been ascertained to a certain extent, and will
receive additional evidence from the facts recorded during our jour-
ney.

The freshwater animals are placed in somewhat different circuit-,
stances. Their abode being circumscribed by dry land within limits

which are often reduced to a narrow current of water, and being far-
ther, for the most part, prevented by structural peculiarities from
passing from the rivers into the ocean, they are confined within nar-
rower limits than either terrestrial or marine types. Within these
limits again they are still farther restricted ; the shells and fishes of
the head-waters of large rivers, for instance, being scarcely ever the
same as those of their middle or lower course, few species extending
all over any freshwater basin from one extreme of its boundary to the
other : thus forming at various heights above the level of the sea,

^j cj

isolated groups of freshwater animals in the midst of those which in-
habit the dry land. These groups are very similar in their circum-
scription to the islands and coral reefs of the ocean ; like them they
are either large or small, isolated and far apart, or close together in
various modes of association. In every respect they form upon the
continents as it were a counterpart of the archipelagoes.

From their circumscription, these groups of lakes present at once
a peculiar feature in the animal kingdom, their inhabitants being en-
tirely unconnected with any of the other living beings which swarm
around them. What, for instance, is there apparently in common
between the fishes of our lakes and rivers, and the quadrupeds which
inhabit their shores, or the birds perching on the branches which
overshadow their waters ; or what connection is there between the
few hermit-like terrestrial animals that live upon the low islands of
the Pacific, and the fishes which play among the corals, or in the
sand and mud of their shores ? And nevertheless there is but one
plan in the creation ; freshwater animals under similar latitudes are
as uniform as the corresponding vegetation, and however isolated and
apparently unconnected the tropical islands may seem, their inhabi-
tants agree in their most important traits.

The best evidence that in the plan of creation animals are intended
to be located within circumscribed boundaries, is farther derived from
their regular migrations. Although the Arctic birds wander during
winter into temperate countries, and some reach even the warmer
zones ; although there are many which, from the colder temperate
climates, extend quite into the tropics, there is nevertheless not one
of these species which passes from the northern to the southern hem-
isphere ; not one which does not return at regular epochs to the

248 LAKE SUPERIOR.

countries whence it came from. And the more minutely we trace
this geographical distribution, the more we are impressed with the
conviction that it must be primitive, that is to say, that animals must
have originated where they live, and have remained almost precisely
within the same limits ever since they were created, except in a few
cases, where, under the influence of man, those limits have been
extended over large areas. To express this view still more distinctly,
I should say that the question to be settled is, whether for instance
the wild animals which live in America originated in this continent,
or migrated into it from other parts of the world ; whether the black
bear was created in the forests of New England and the Northern
States, or whether it is derived from some European bear, which by
some means found its way to this continent, and being under the
influence of a new climate, produced a new race ; whether the many
peculiar birds of North America which live in forests composed of
trees different from those which occur either in Europe or Asia,
whether these birds, which themselves are not identical with those of
any other country, were or were not created where they live ;
whether the snapping turtle, the alligator, the rattlesnake, and other
reptiles which are found only in America, have become extinct in the
Old World after migrating over the Atlantic, to be preserved in this
continent ; whether the fishes of the great Canadian lakes made their
appearance first in those waters, or migrated thither from somewhere
else ? These are the questions which such an inquiry into the geo-
graphical distribution of animals involves ; it is the great question of
the unity or plurality of creations ; it is not less the question of the
origin of animals from single pairs or in large numbers ; and, strange
to say, a thorough examination of the fishes of Lake Superior, com-
pared with those of the adjacent waters, is likely to throw more light
upon such questions, than all traditions, however ancient, however
near in point of time to the epoch of creation itself.

In order to proceed methodically in this investigation, our first
step must be to examine minutely, whether the fishes of Lake Supe-
rior are the same as those of other lakes in this or any other country,
and if not, how they differ. To satisfy ourselves in this respect, AVC
shall successively examine all the families of fishes which have repre-
sentatuos in those great fieshwater seas.

FISHES OF LAKE SUPERIOR. 249

PETROMYZOXTID.E (Lamprey -eels.)

There are families in all departments of nature, whose peculiarities
call for an investigation of their more general relations rather than of
their structural details. The Petromyzons are in this case. Closely
allied together and circumscribed in a most natural family, it is a ques-
tion whether they should be entirely separated from all other fishes
to form a great group by themselves, or whether they belong to one
of those great divisions in which the individual members differ widely
from each other. In other words, should the Petromyzons stand by
themselves in a natural classification of fishes, as Prince Canino and
Joh. Mliller have placed them, or shall we combine them with skates
and sharks, as Cuvier has done ? To answer such a question, it is
necessary to discuss beforehand principles of the utmost importance
in the study of natural history, and above all to settle the folio w-
ing difficulty : — Is the study of anatomical structure an absolutely
safe guide in the estimation of the relations of animals to each other ?
Cuvier, who made the study of comparative anatomy the foundation
of classification, carried out this principle in a most remarkable man-
ner, and improved the natural arrangement of animals most sur-
prisingly ; indeed, he made zoology truly a science by it ; but with
a tact that characterizes genius, he limited the absolute consequences
of this law by a true appreciation of the relative value of characters ;
introducing at the same time with the principle of classification ac-
cording to the structure of animals, that of subordination of charac-
ters, without which the first great principle might mislead us, instead
of helping to ascertain the true relations of organized beings. Now
it seems to me as if zoologists and anatomists had of late insisted too
strictly upon the absolute differences which exist between animals,
instead of attempting to appreciate the relative value of the differ-
ences noticed. Of course, as this latter point rests almost within the
limits of individual appreciation, it is more difficult to find the right
path here, than in almost any other department of zoological investi-
gations ; but I hope to be able to introduce another great principle
of zoological classification, which shall afford a safe guide to settle
such doubts ; I mean the study of embryonic development.

Let me now show, in the present instance, how I consider it possible
17

250 LAKE SUPERIOR.

to be led by anatomical evidence considered in its absolute results, to
combinations strictly opposed to those which an additional acquaint-
ance with embryonic development might indicate.

Guided by his admirable natural feeling of affinities, Cuvier placed
in one and the same great division, sharks, skates, and lamprey-eels.
Influenced by anatomical investigation, and indeed by the most min-
ute and admirable knowledge of their anatomical structure, derived
from unparalleled investigations, Joh. Mttller concluded, on the con-
trary, that the Cyclostomata were to be separated from the other
cartilaginous fishes, and placed by themselves at the other end of
the class. Who is right in this case cannot be ascertained by any
farther anatomical investigation ; it has thenceforth become a matter
of individual appreciation, unless we introduce another principle, by
which we can weigh the real value of these remarkable differences.
Such a principle, I think, we have in the metamorphosis of embryonic
life. Indeed, if it can be shown, that besides the differences which
exist in all fishes between their earliest forms and their full-grown
state, there are peculiarities in sharks, skates, and lamprey-eels
common to all of them, from an early period of development, which
remain characteristic throughout life, it must be acknowledged that
these families belong to one and the same great group, notwithstand-
ing their extreme differences in their full-grown condition. Now,
such facts exist. In the first place, it is impossible, without disturb-
ing their true affinities, to consider an extraordinary development of
pectoral and ventral fins as a standard to appreciate fundamental
relations between fishes, as in all fishes, without exception, they are
both wanting in earlier life, and as there is scarcely a family in which
ventrals at least, are not wanting in some genus or other. We might
just as well place Petromyzons among the eels, as their common
English name purports, on the ground of the deficiency of their
abdominal and thoracic organs of locomotion, as separate them from
the other Placoids. Again, the peculiarities in the development of
the dorsal, caudal, and anal fins in sharks and skates, and the differ-
ences which exist between them and the Petromyzons, indicate in
no way their affinity or their difference ; in Petromyzon we have the
embryonic condition of vertical fins, where a continuous fold in the
skin of the middle line extends, as in aU embryo fishes, from the back

FISHES OF LAKE SUPERIOR. 251

round the tail, towards the abdominal region. In the sharks we
have distinct vertical fins, as they generally grow out of the continu-
ous, embryonic odd fin ; whilst in skates these fins disappear almost
entirely, or are considerably reduced. That animals in their embry-
onic condition are neither so elongated as many of cylindrical form in
their full-grown state, nor so short as some others, is ascertained by
the embryology of snakes and toads. Thus, all the great external
differences which exist between skates and pharks on one side, and
Petromyzon on the other, do not show that these animals do not
belong to the same natural group, as we have even among the full-
grown ones, what we may call transitions between the extreme forms ;
for instance, sharks with more elongated body than others, with more
extensive vertical fins, even with two dorsals and some without ven-
trals. Again, the remarkable form of skates arises solely from an
extraordinary development of the pectorals ; they are nevertheless
closely allied to sharks, notwithstanding the striking difference in the
position of the gill-openings.

As for the anatomical differences which exist among these fishes,
and upon which so much stress is placed as to make the want of a
heart, in Amphioxus, the foundation for a peculiar class to include that
single fish, let us not forget, that there is an epoch in embryonic life,
when no vertebrated animal has yet a heart ; when the vertebral
column is a mere soft continuous cord ; when the brain is scarcely
subdivided into lobes ; when the head, as such, is not yet distinct
from the trunk ; when the mouth is a mere circular opening at the
anterior extremity of the body ; when the gills are simple fissures on
the sides of the head, or at what is to be a head, without branchio-
stegal rays or operculum, or protecting covering of any kind.

Whoever is familiar with the anatomy of fishes must perceive, after
these remarks, that the peculiarities which - characterize Petromy-
zon, have a bearing upon the embryonic condition of their structure
even in their full-grown state, and do not by any means mark a dif-
ference between them and the sharks and skates, any more than
between them and any other family of fishes. On the contrary,
should it be possible, after these statements, to show that there are
important characters, common to Petromyzon, sharks and skates,
notwithstanding their extreme external differences, it should be

252 LAKE SUPERIOR.

acknowledged that Cyclostomata and Plagiostomata are only different
degrees of one and the same great type. Now, such characters we
have ; in the first place, in the structure of the mouth, which differs
so widely from that of the other fishes, and agrees so closely in all
Placoids, as Muller himself has shown in his Anatomy of Myxinoids.
Next, the teeth also agree, in being arranged in several concentric
series, and also in their microscopical structure, as well as in their
mode of attachment to the skin lining the jaw, and not to the bone
itself. We have other hints of the relation between Cyclostomes
and Plagiostomes in their spiracles, and also in their numerous respi-
ratory apertures, so that, after due consideration, I come to the con-
clusion that the Myxinoids and Petromyzons, far from being the types
of peculiar subclasses, are simply embryonic forms of the great type
to which sharks and skates belong, bearing to these powerful ani-
mals, in a physiological point of view, the same relation which exists
between Ichthyodes and the tailless batrachians.

Of Cyclostomata, two species have been mentioned as occurring in
the colder parts of North America, both referred by Dr. Richardson
to the genus Petromyzon proper, but of which I have seen no trace
myself in the great lake region, though I know Petromyzons to occur
below Niagara Falls. However, I am able to add a new species of
this family to the fauna of those waters, which belongs to the genus
Amniocoetes, and was found in the mud in Michipicotin River, at the
landing place of the Factory, the first specimens of which were picked
up by the students when dragging their canoes along the shore.

AMMOC(ETES BOREALIS, Agass.

This pretty little species differs from all those already known, by
easily appreciable characters. It is at first sight plainly distinguished
from the Ammocoetes bicolor, Les. and A. branchialis, Dum. whose
dorsal fin is, as it were, divided into two lobes by a very low emargina-
tion ; but it resembles the Am. concolor, Kirt. and unicolor, Dekay,
in its dorsal fin, being uniformly continuous. It differs, however, from
this latter, whose form is much more elongated, by the extent of its
dorsal fin, which equals one half of the whole length of the body, whilst
in the Am. unicolor it extends scarcely before the anus. In the

FISHES OF LAKE SUPERIOR. 253

individual which has served for this description, the whole length
exceeds a little five inches.

The general form of the body is compressed, differing still in
that respect from A. unicolor, which is subcylindrical, whilst the
concolor is cylindrical at its anterior, and compressed at its posterior
part. Our species is, on the contrary, in some manner ribbon-like,
and its length goes on diminishing regularly from the neck towards
the tail, where it ends in an attenuated and obtuse caudal lobe.
The neck is prominent, but the skull is declivous. The upper lobe
of the mouth, which terminates the anterior extremity, is concave,
the opening of the cavity which it circumscribes being turned
downwards. The anterior margin of the lip is concave, the lateral
margins describe a convex lobe to the angles of the mouth. The
lower lip is completely distinct from the upper, small and fixed upon
the anterior of the lateral margins of the upper ; it is slightly con-
cave about the middle of its circumference. The convex lateral
lobes are elliptical. The mouth, placed in the centre of the funnel
formed by the two lips, is proportional to the size of the fish. When
it is shut it seems to be cleft vertically, though in reality it is cir-
cular. The branched fringes which surround the mouth, are
especially developed on the lower lip and at the angles of the mouth ;
they lengthen, but are reduced in thickness, on the inner side of the
upper lip, under the form of an isosceles triangle, whose interior
is equally furnished with them. The opening of the nose is situate
in a circular depression betAveen the anterior extremity of the
skull and the inner margin of the upper lip. This depression
is continued upwards, and terminates about the middle of the skull.
The eyes are very small and placed on the sides of the head, at the
height of the angles of the mouth, in a slight furrow of the face.
The branchial openings are subcircular or convex in front, truncated
behind, and open in a wrinkled furrow half an inch long, in form of a
very elliptical curved line. The first branchial opening is at a dis-
tance of ~6 of an inch behind the angles of the mouth. The anus opens
in a depression at a distance of | of an inch from the extremity of the
caudal fin ; it is cleft longitudinally, and bordered by two thinned lips.
The anal fin, very low at its origin immediately behind the anus, widens
a little as it advances towards the caudal, with which it unites after

254 LAKE SUPERIOR.

having produced a more marked lobe. The dorsal fin is higher, but
like the anal grows in height towards the posterior extremity, and
forms like it a more dilated lobe before it unites with the caudal.
This latter extends over an equal length above and below the tail.
It is separated from the dorsal and anal fins by a notch, beyond which
the fin arises to the height of the terminal lobes of the two anterior
fins, and preserves the same height along the whole circumference of
the tail, under the form of an elongated oval. Undulated, annular,
transverse lines, distinct enough on the sides of the body, corres-
ponding with the lateral muscles of the trunk, are very marked.

This species is from Michipicotin, where we have picked up a rather
large number of specimens.

LEPIDOSTEUS.

This genus of fishes is known throughout the United States
under the name of gar-pike. It is a very singular animal, and its his-
tory is closely connected with the most important progress which has
recently been made in ichthyology. .

The first knowledge naturalists had of this remarkable fish was
derived from Catesby, who published a figure and a short account
of it in his Natural History of South Carolina.

V

Linnoeus, who received specimens of the same species from Dr.
Garden of South Carolina, introduced it into his Systema Naturoe
under the name of Esox osseus, supposing it allied to the common
pickerel, because its dorsal and anal fins are opposite to each other
and far back, near the end of the tail.*

Lacepede, who first noticed some of its peculiarities, removed it
from the genus Esox, and established a distinct genus for it, under
the name of Lepisosteus, which name, however, not being quite
grammatically correct, I afterwards modified to Lepidosteus, which
is now generally received.

The French naturalist knew a second species of that genus, from
the Mississippi, which he called Lejridosteus Spatula. Afterwards

page 33.

FISHES OF LAKE SUPERIOR. 255

Rafinesque described several more, which, however, can scarcely be
identified, as his descriptions are so very short and imperfect as to
give little information upon their structure. In his Animal Kingdom,
Cuvier characterized the genus Lepidosteus more correctly than his
predecessors, without, however, noticing the great difference which
exists between this genus and the common Abdominales among which
he places it.

It was my good fortune early in the course of my scientific studies
to perceive the striking differences which exist between these Lepidos-
tei and all the other fishes now living upon our globe ; and at the
same time to call the attention of naturalists to the close relationship
which exists between them and the fossil fishes of the earlier geologi-
cal ages. So that, after an extensive study of the remains of these
ancient inhabitants of olden time, Lepidosteus has become notable as
the only living representative of the large group of fishes which peo-
pled, almost exclusively, the waters during the early ages of the
earth's history, and which has gradually decreased in number, until,
at last, he was left almost alone to remind the observers of the present
age, of a once powerful and widely spread dynasty among the watery
tribes.

These facts call for a close examination of this singular fish. In
the first place, let me say, that all the species of Lepidosteus^ of
which I now know ten distinct species, inhabit exclusively the fresh
waters of North America. This is, in itself, a remarkable fact,
most important in the history of nature, as it shows that far from de-
riving its inhabitants from other parts of the world, America has
had, and has now, animals which are entirely peculiar to it, and
which have nowhere any near relatives.

I am well aware that the Bichir of the Nile is remotely allied to
the gar-pikes, and that another species of Polypterus occurs also in
the Senegal ; but this genus constitutes also by itself a peculiar
group, and can only be considered as distantly related to the Lepi-
dostei.

Another remarkable peculiarity in the geographical distribution of
these fishes consists in the fact that different species are limited to
different water basins, as the species of the Middle and Southern
Atlantic States are as different from those of the Western waters as

251! LAKE SUPERIOR.

they are from the species which occur in the Northern lakes ; so
that, not only is the genus located in a peculiar continent, but the
individual species are also confined to special regions of this coun-
try, from the great Canadian lakes to the freshwaters of Florida, and
from the Atlantic rivers to the numerous affluents of the Mississippi.
New England, however, has no species, and this is the more surpris-
ing as they occur further north in the St. Lawrence, and further
south in the Delaware.

The question now arises, how this genus of fishes stands in its
class ; and whether, notwithstanding their peculiarity, they may not
be associated with some other families.

Before answering this question, let me insist upon another fact,
that, even if we take into account the nominal species of Rafinesque
and that beautiful species of the Northern lakes first described by
Dr. Richardson, the Lepidostei are only ten in number. And if we
introduce into the same general division, the Polypteri, we shall
have a natural group of fishes containing in the present creation not
mere than a dozen species. And even should we suppose that
some more relatives of that group may be discovered in the course of
time, we can by no means suppose that this family would ever contain
as large a number of species as most of the other families of the class.
We need only remember the innumerable species of suckers, or of
cat-fishes, which occur every where in our fresh waters, or the
various kind of perch, mackerel, codfish, &c., which swarm in the
ocean, and among which the new discoveries to be expected can
hardly be fewer than among our Lepidostei, to be satisfied that there
is here a remarkable contrast between these families. It is therefore
a fact plainly shown by this evidence, that the most natural groups
of animals which we discover in nature, differ widely among them-
selves in the number of their representatives.

It is not less obvious, that these groups differ from each other in a
very unequal degree, taken as general groups or considered in the
isolated members of their families.

The amount of difference which distinguishes the gar-pikes from
the common pickerels, or from the trouts. or from the herrings,
or from the suckers, is far greater, for instance, than that which dis-
tinguishes the pickerels from the trouts, or the trouts from the

FISHES OF LAKE SUPERIOR. 257

herrings ; and again, the generic differences which occur among
the trouts, the graylings and white-fishes, and distinguish them from
true salmon, are far greater than that which exists between the chubs,
gudgeons, barbels or carps ; and the specific distinctions which may
be noticed in these different genera are again of an unequal value.
So that we arrive at once to this important conclusion, that
natural groups in the animal kingdom show naturally differences of
unequal value, and that all attempts on the part of naturalists to
equalize the divisions which they acknowledge in their researches,
must, as a matter of course, result in failure; and I have not the
slightest doubt that our classifications have not been more improved,
and that we have made less extensive progress in the knowledge
of the true relationship between the various groups of the animal king-
dom, for the very reason that we have too often aimed at an arrange-
ment which the most familiar facts in nature plainly contradict.
Instead of this desired uniformity, we sometimes observe a numer-
ous group of closely allied species corresponding to another group
with few, but more distinct and more widely different species, and
even isolated types, the relation of which seems to branch in
all directions, without ever coming very close to any other group.
Now, unless our classifications admit, as a natural limit, this diver-
sity, it will be impossible ever to form a system which will answer
to the natural affinities really existing in nature. As I have said on
another occasion,* classification should be a picture from nature, and
not an artificial frame of our own invention, into which natural objects
are more or less conveniently brought together.

Another important point of view, of which naturalists should never
lose sight, is the relation which exists between animals now found
alive on various parts of the surface of our globe, and those known
to us only from fossil remains discovere'd in strata of a different geo-
logical age.

The Lepidosteus, however isolated in the present creation, had
once many and very diversified representatives all over the globe.
Fossils of the same family of which the gar-pike is the type, have been
found all over Europe in the oldest fossiliferous beds, in the strata of
the age of the coal ; in the new red sandstone ; in the oolitic deposits,

* See Principles of Zoology, by L. Agassiz and A. A. Gould, Vol. II.

258 LAKE SUPERIOR.

and even in the chalk and tertiary beds. Thej existed in the same
wide range upon the continent of North America, and have been found
in Asia as well as in 'New Holland ; so that this family, now limited to
the continent of North America, and, if we include in it the Bichir
also, to two river basins of Africa, — was once cosmopolite in its
geographical distribution.

The natural consequence from such evidence is, that we cannot
arrive at a true insight into the relations of the animal creation, unless
we study, at the same time, the living animals, and those which have
become extinct ; and that a natural classification must associate the
fossils promiscuously in their natural relationship with the living
types. The separation of palaeontology from zoology, for the sake
of convenience in the study of geological phenomena, has been very
injurious to the real progress of zoology, and is so entirely unscientific,
that until they are again combined under the same head, even in our
elementary text books, we can hardly expect that zoology will make
the progress which extensive investigations carried on singly, in the
study of living and fossil animals, would lead us to expect.

Moreover, the identification of fossils requires a close investiga-
tion of such characters as are shown in the only remains of extinct
species which have been preserved, and which are, almost exclusive-
ly, their solid parts. It is therefore very important that, in zoological
investigations, more attention should be paid to the characters derived
from such parts as are the only ones accessible in the study of fossils.

The mutual advantages to be derived from such a course cannot but
be strikingly felt by those who have devoted their attention to the
study of fossils. It may even be said that the condition of fossil re-
mains, as they generally occur in rocks, has led naturalists to study
more carefully the living species, than they did before. I need only
mention the minuteness with which the skeletons of living animals
have been described since it has been necessary to identify extinct
species from isolated bones.

The skeletons of fishes, which were neither correctly figured in
zoological drawings of these animals, nor minutely examined in their
structure, are no longer considered as unworthy of the attention of
minute observers. Even our knowledge of the structure of the
shells in rnollusca and of the wings of insects, has been improved with

FISHES OF LAKE SUPERIOR. 259

reference to the identification of fossil remains. It is therefore plain
that comparative anatomy should be more extensively and intimately
combined with zoology than is generally the case. The classification
of the animal kingdom should no longer be based simply upon the
structure of the animals, but form and structure should everywhere
and always be considered in their intimate connections.

I have already alluded to the narrow circumscription of the genus
Lepidosteus, within the limits of the temperate zone of North Amer-
ica. In like manner, also, the Marsupialia, for instance, are almost
wholly confined to New Holland, and the Edentata to .Brazil. All
this goes to show that there is an important connection between a
given country and its inhabitants, which rests with the primitive plan
of the creation.

The limited existence of Lepidosteus in North America in the pre-
sent creation has, no doubt, reference to the fact that North America
was an extensive continent long before other parts of the globe had
undergone their most extensive physical changes. Or in other
words, that the present character of this continent has not been
much altered from what it was when the ancient representatives of
Lepidosteus lived ; while in other parts of the world, the physical
changes have been so extensive as to exclude such forms from
among the animals suited for them.

We have therefore here a hint towards a more natural and deeper
understanding of the laws regulating the geographical distribution of
animals in general.

There are animals and plants whose detailed history is, as it were,
at the same time, the history of that branch of science to which they
belong. This is particularly the case with those animals, which,
from particular circumstances, have thrown unusual light upon the
relations which exist between them and their allied types. There
are even a few such animals, the study of which has actually marked
the advance of science. I cannot notice on this occasion the gar-
pike without being strongly reminded how strikingly this has been
the fact with Lepidosteus. The first sight I had of a stuffed skin of
that fish in the Museum of Carlsruhe, when a medical student in the
University of Heidelberg, in 1826, convinced me that this genus stood
alone in the class of fishes ; and that we could not, by any possibility,

260 LAKE SUPERIOR.

associate it with any of the types of living fishes, nor succeed in
finding, among living types, any one to associate fairly with it. It
was a fact, at once deeply impressed upon my mind, that it stands iso-
lated among all living beings ; and this early impression has gradually
led me to the views respecting classification which I have expressed
above, and which have frequently guided me in appreciating both
the various degrees of relationship, and also the differences which I
have noticed among different families ; and, I may say, has also kept
me free from fanciful attempts at symmetrical classifications.

Somewhat later, my investigations of the fossil fishes led me to
the distinct appreciation of the great difference there is between the
characters of the class of fishes in early geological ages ; I also
noticed that all the bony fishes of former ages are more or less
allied to the gar-pike, and widely different from the types of
fishes now prevailing. But the real nature of this difference was
only gradually understood. I had not yet perceived that the fishes
of older times had peculiar characters of their own, not to be
found either among the more recent fossils or among the liv-
ing representatives of that class. But the opportunity of study
ing the skeleton of Lepidosteus, which was afforded me in Paris by
Cuvier, showed at once, that these fishes have reptilian characters.*

The articulation of their vertebrae differs from that of the verte-
brae of all other fishes no less than the structure of their scales.
Their extremities, especially the pectoral limbs, assume a higher
development than in fishes generally. Their jaws also, and the
structure of their teeth, are equally peculiar. Hence, it is plain
that, before the class of reptiles was introduced upon our globe,
the fishes, being then the only representatives of the type of verte-
brata, were invested with the characters of a higher order, embody-
ing, as it were, a prospective view of a higher development in
another class, which was introduced as a distinct type only at a
later period ; and from that time the reptilian character, which had
been so prominent in the oldest fishes, was gradually reduced, till,

the successive creations all this herpetological relationship, and were,
at last, endowed with characters which contrast as much, when com-
pared with those of reptiles, as they agreed closely in the beginning.
Lepidosteus alone reminds us, in our time, of these old-fashioned
characters of the class of fishes, as it was in former days.

An opportunity afforded me by John Edward Gray, Esq., of the
British Museum, of examining a specimen of this genus, preserved
in alcohol, furnished another evidence that the reptilian character
of Lepidosteus was not only shown in its solid parts, but was even
exemplified in the peculiar structure of its respiratory apparatus and
its cellular air bladder, as I have pointed out in the Proceedings of
the Zoological Society of London.*

One step further was made during this excursion, when, at Niag-
ara, a living specimen of Lepidosteus was caught for me, and to my
great delight, as well as to my utter astonishment, I saw this fish
moving its head upon the neck freely, right and left and upwards,
as a Saurian, and as no other fish in creation does.

This reptilian character of the older fishes is not the only striking
character which distinguishes them. Investigations into the em-
bryonic growth of recent fishes have led me to the discovery that
the changes which they undergo agree, in many respects, in a
very remarkable manner, with the differences which we notice be-
tween the fossils of different ages ; so much so, that the peculiar
form of the vertebral column, and especially its odd termination hi
very young embryos, where the upper lobe of the caudal fin is pro-
longed beyond the lower lobe, and forms an unequal, unsymmetrical
appendage upwards and backwards, agrees precisely with the form
of the tail of the bony fishes of the oldest geological deposits ; so
that these ancient fishes may be said to have embryonic peculiarities
in addition to their reptilian character. This fact, so simple in itself,
and apparently so natural, is of the utmost importance in the history
of animal life. It has gradually led me to more extensive views, and
to the conviction that embryonic investigations might throw as much
light upon the successive development of the animal kingdom during
the successive geological periods, as upon the physiological develop-

ment of individual animals ; and, indeed, I can now show, through all
classes of the animal kingdom, that the oldest representatives of any
family agree^ closely with the embryonic stages of the higher types of
the living representatives of the same families ; or, in other words,
that the order of succession of animals, through all classes and
families, agrees, in a most astonishing measure, with the degrees of
development of young animals of the present age.

This being the case, it is obvious that a minute investigation of the
embryology of Lepidosteus would throw a vast amount of light upon
the history of the succession of fishes, of all geological periods ; and
also would probably give the first indication of the manner in which
the separation of true ichthyological characters from reptilian char-
acters, Avas gradually introduced ; as it is more than probable, from
all we know otherwise of the embryology of animals, that the young
gar-pike, in its earliest condition, will have characters truly ichthy-
ological, and only assume, gradually, the peculiar reptilian charac-
ters which distinguish it. But notwithstanding all my efforts to
secure the Lepidosteus in the breeding season, I have failed up to
this day to gain the desired information. It only remains for me,
therefore, to urge naturalists living near the waters inhabited by
Lepidosteus to take up the subject as early as an opportunity is
afforded them.

Although Lepidosteus does not occur in Lake Superior, I have
deemed it sufficiently important to introduce these remarks here, as
this fish occurs in all the northern lakes except Lake Superior, as
far north even as Mud Lake, below Sault St. Marie. Its presence
in these waters is another of the striking differences which exist
between the ichthyological fauna of Lake Superior, and that of the
other lakes ; and shows once more, within what narrow limits animals
may be circumscribed, even when endowed with the most powerful
means of locomotion, and left untrammeled by natural barriers.

This Lepidosteus is one of the swiftest fishes I know. He darts like
an arrow through the waters, and the facility with which he overcomes
rapids, even the rapids of the Niagara, shows that the falls of St.
Mary would be no natural barrier to him, if there were no nat-
ural causes to keep him within the limits in which he is found,
which extend from Lake Michigan, Lake St. Clair, and Mud

FISHES OF LAKE SUPERIOR. 263

Lake, through Lake Erie, and Ontario, down to the St. Lawrence
and its outlet into the sea, into which this fish never ventures far,
though he does not altogether avoid brackish and salt water.

Dr. Richardson was the first naturalist who described the northern
Lepidosteus. He mentions it in his Fauna Boreali-Americana,
under the name of Lepidosteus Huronensis, and gives a correct and
detailed description of it. Nevertheless, it has been since mistaken,
and referred to the southern species first described by Catesby and
Linnseus, from which it is however very distinct, both by the pro-
portions of its parts, its scales, its fins, and especially by the form of
its frontal bones, in which the supra-orbital emargmation is much
lower and more elongated. Again, notwithstanding the descrip-
tion of Dr. Richardson, Dr. Dekay has redescribed it under the
name of Lepidosteus Bison; and Zadock Thompson has described
a young specimen under the name of Lepidosteus lineatus. At
first, his description would seem to indicate a really distinct
species ; but I have ascertained, by a series of specimens, that the
differences pointed out are really the characters of the young, and
have no value as specific characters ; the detached lobe formed by
the upper raylets of the caudal fin is gradually united with the
lower rays,* and the longitudinal stripe, which is well marked in
young specimens of a few inches in length, gradually vanishes, to
leave only a few spots upon the sides, which even disappear entirely
in the oldest individuals. The vertical fins alone remain spotted in
the adult. The natural color of this fish is a light greenish gray,
passing downwards into a dull white.

ACIPENSERID^E (Sturgeons.*)

The family of Sturgeons is well characterized and easily distin-
guished from any other in the class. These fishes have generally
been placed in the order of Chondropterygians, near the sharks,
until I objected to this association, and attempted to show that, not-

* It is a very remarkable fact that several fishes of the old Red Sandstone period
have, in their full-grown state, a peculiar form of their caudal fin, which is nearly
identical with the form of the caudal fin of the young Lepidosteus ; a form which
is otherwise unknown to me at present in the whole class of fishes.

264 LAKE SUPERIOR.

withstanding their extraordinary peculiarities, they are more closely
related to the gar-pikes, than to any other group of fishes. This
view, though at first strongly opposed, is now generally admitted,
having been sustained both by anatomical and palgeontological
evidence.

The sturgeons are generally large fishes, which live at the bot-
tom of the water, feeding with their toothless mouths upon decom-
posed organized substances. Their movements are rather sluggish,
resembling somewhat those of the codfish tribe.

Their geographical distribution is quite peculiar, and constitutes
one of their prominent peculiarities. Located as they are, in the
colder portions of the temperate zone, they inhabit either the fresh
waters or the seas exclusively, or alternately both these elements,
remaining during the larger part of the year in the sea, and ascend-
ing the rivers in the spawning season. Although adapted to the
cold regions of the temperate, they do not seem to extend into
the arctic zone, and I am not aware that they have been observed in
any of the waters of the warmer half of the temperate zone. The
great basin of salt water lakes or seas which extends east of the Med-
iterranean, seems to be their principal abode in the Old World, or at
least the region in which the greater number of species occur ; and
each species takes a wide range, extending up the Danube and its
tributaries, and all the Russian rivers emptying into the Black
Sea. From the Caspian they ascend the Wolga in immense
shoals, and are found farther east in the lakes of Central Asia,
even as far as the borders of China. The great Canadian lakes
constitute another centre of distribution of these fishes in the New
World, but here they are neither so numerous, nor do they ever
occur in contact with salt water in this basin.

Northwards, there is another great zone of distribution of stur-
geons, which inhabit all the great northern rivers emptying into the
Arctic Sea, in Asia as well as in America. They occur equally in
the intervening seas, being found on the shores of Norway and
Sweden, in the Baltic and North Sea, as well as in the Atlantic
Ocean, from which they ascend the northern rivers of Germany, as
well as those of Holland, France, and Great Britain. Even the
Mediterranean and the Adriatic have their sturgeons, though few

FISHES OF LAKE SUPERIOR. 265

in number. There are also some on the Atlantic shores of North
America, along the British Possessions as well as the Northern and
Middle United States. They seem to be exceedingly numerous in
the northern Pacific, being found everywhere from Bearing's Straits
and Japan to the northern shores of China, and on the north-west
coast of America, as far south as the Columbia River. Again, the
so called western waters of the United States have their own
species, from the Ohio down to the lower portion of the Mississippi,
but it does not appear that these species ascend the rivers from the
Gulf of Mexico. I suppose them to be rather entirely fluviatile, like
those of the great Canadian lakes.

Beyond the above limits southwards there are nowhere sturgeons
to be found, not even in the Nile, though emptying into a sea in
which they occur; and as for the great rivers of Southern Asia and
of tropical Africa, not only the sturgeons, but another family is
wanting there, I mean the family of Goniodonts which in Central
and Southern America takes the place of the sturgeons of the
North. Again, all the species in different parts of the world are
different.

It is a most extraordinary fact, which will hereafter throw much
light upon the laws of geographical distribution of animals and their
mode of association, viz., that certain families are entirely circum-
scribed within comparatively narrow limits, and that their special
location has an unquestionable reference to the location of other ani-
mals ; or in other words, that natural families, apparently little related
to each other, are confined to different parts of the world, but are
linked together by some intermediate form, which itself is located in
the intermediate track between the two extremes. In the case now
before us, we have the sturgeons extending all around the world in
the northern temperate hemisphere, in its seas as well as in its fresh
waters, all closely related to each other. Neither in Asia nor in
Africa is there an aberrant form of that type, or any representative
type in the warmer zones ; but in North America we have the
genus Scaphirhynchus, which occurs in the Ohio and Mississippi, and
which forms a most natural link with the family of Goniodonts, all the
species of which are confined exclusively to the fresh waters of
Central and South America. The closeness of this connection will be

18

at once perceived by attempting to compare the species of true
Loricarise with the Scaphirhynchus. I know very well, that the
affinities of Goniodonts and Siluroids with sturgeons are denied, but
I still strongly insist upon their close relationship, which I hope to
establish satisfactorily in a special paper, as I continued to insist
upon the relation between sturgeons and gar-pikes, at one time
positively contradicted, and even ridiculed. I trust then to be able
to show, that the remarkable form of the brains of Siluridse comes
nearer to that of sturgeons and Lepidostei, than to that of any
other family of fishes. This being the case, it is obvious, that there
must be in the physical condition of the continent of America some
inducement not yet understood, for adaptations so special and so
different from what we observe in the Old World. Indeed, such anal-
ogies between the organized beings almost from one pole to another,
occur from man down to the plants in America only, among its native
products ; while in the Old World plants as well as animals have more
circumscribed homes, and more closely characterized features in the
various continents at different latitudes.

•

As for the species of sturgeons which occur in the Canadian
lakes, I know only three from personal examination, one of which was
obtained in Lake Superior, at Michipicotin, another at the Pic, and the
third at the Sault : though I know that they occur in all other Cana-
dian lakes, yet it remains to be ascertained how the species said to be
so common in Lake Huron, <^>mpare with those of Lake Superior, and
with those in the other great lakes and the St. Lawrence itself. As
for the Atlantic species, ascending the rivers of the United States
west and south of Cape Cod, I know them to differ from those of the
lakes, at least from those which I possess from Lake Superior. The
number of species of this interesting family which occur in the United
States is at all events far greater than would be supposed from an
examination of the published records. Upon close comparison of the
specimens in niy collection from different parts of the country, and
in different museums, as those of the Natural History Society of
Boston, of Salem, of the Lyceum of New York, my assistant, Mr.
Charles Girard, and myself have discovered several species not yet
described. For this comparison I was the better prepared as I had

FISHES OF LAKE SUPERIOR. 267

an opportunity in former years of studying almost all the European
species in a fresh condition, during a prolonged visit in Vienna.

ACIPENSER L^BVIS, Agass.

This species, one of the largest of the genus, is from the Pic.
The length of the specimen, of which I possess the head and the
fins, and which was in fresh condition when I examined it, was four
feet six inches. The head, which is contained two and a half times in
the whole length, is subconical and a little flattened below ; the upper
surface forms an uniformly descending line from the occiput to the ex-
tremity of the snout, somewhat elliptical beyond the eyes, thus giving
to the latter a slightly recurved appeai^ance. From the level of the
eyes to the centre of the skull, on the middle line of the head, there
exists an equally elongated surface, more flattened, being the rudi-
ment of a longitudinal dimple ; finally, on the occipital part of the skull
we observe a small keel, where the two bones of this region begin
to become convex, in order to pass to the cutting plates of the back.

The surface of the bones which form the exterior covering of the
head, is invested with small tubercles of enamel, of a circular form
with obtuse summits. At first without apparent order, at the very
centre of the bone they become linear, radiating to the circumfer-
ence. Their greatest development occurs in the occipital region and
on the transverse line level with the nostrils. On the middle part
of the head these tubercles become thinner, and on the extremity of
the snout they are reduced to a fine reticulation. The sides of the
head have only a very few asperities. The only bone on which they
are developed is the operculum, and it is only in its posterior half
that they radiate from the centre towards the margin. A few rows
only are directed towards the upper part of the head. The other
bones constituting the opercular apparatus are covered with a
membrane finely roughed at the surface. The bones placed at
a small distance behind the eye and limiting the anterior margin of
the branchial cavity, bear a few blunt tubercles irregularly dis-
tributed on their surface. The branchiostegal membrane is naked
and smooth, attached by a thin shred to the posterior part of the
operculum, and passes before the pectoral fin, to which it is con-

268 LAKE SUPERIOR.

tiguous ; beyond this it dilates, in order to shut the branchial cavity
at the lower part of the head, forming a very open curved line ;
finally it terminates at a small distance from the mouth. The eyes
are at a distance of three and six-eighths inches from the end of the
snout. Their form is subcircular, their pupil transversely cleft.
Their immediate covering is a smooth membrane, which continues
below to the anterior extremity, where it becomes reticulated, but
without any appearance of the smallest plate on its surface. At the
anterior and upper part of the eye is a small protuberance projecting
over the depression in which the nostrils are situated. These latter
open at the surface by two orifices on each side. The one of an
elliptical form with a free opening, occupies a prominent position, so
that it would be observed from both sides of the head, looking at it
from above. The other, a larger one, has the form of a crescent, with
its convexity turned towards the eye, and placed a little obliquely
on the vertical line, extending below the lower line of the eye for
two-thirds of its length.

The lower portion of the head appears as a flat surface rising
insensibly from the anterior margin of the mouth to the extremity of
the snout. This latter rises gradually in an oblique line, which begins
in front of the barbels. The middle line is convex, the margins are
inclined. The barbels, four in number, are situated in pairs on both
sides. The two pairs are a little more distant from each other than
the two barbels of the right and left side. Their length is nearly
the same, of about two inches ; their form subconical, growing thinner
at their extremity. Behind the barbels we notice a subquadrangular
depression in which their base is concealed when they bend back-
wards. The mouth is situated on the anterior half of the lower
part, in a transversal notch ; it extends from one side of the head
to the other, the posterior margin being almost straight, the anterior
having an elliptical outline on the middle line. A thick membrane,
with a glandular and undulating surface, surrounds the jaws, leav-
ing the symphysis of the lower jaw free. Both extremities are
attached to the anterior third part of both lower maxillary bones,
sending a small membranous expansion towards the symphysis, tak-
ing afterwards the direction towards the angles of the mouth.

FISHES OF LAKE SUPERIOR. 269

Here the membrane is thickened considerably, and continues so on
the whole circumference of the upper jaw, following its outlines.

The mouth is protractile, and when projected outwards carries
with it the surrounding membrane. The jaws are weak, both max-
illary branches of the upper and lower jaw uniting by means of a
tendinous membrane. The extremity of the tongue is round, cov-
ered with a thick membrane, with a wrinkled surface perforated with
small mucous holes.

A thick layer of mucosity covers the surface of the head. This
mucosity is secreted by the crypts of the skin ; these are especially
very conspicuous on the space situated between the mouth and the
snout, and on the upper side of the latter. They have the appear-
ance of irregular meshes excavated in the skin, at the bottom of
which we distinguish, by means of a magnifying glass, the crypts
which line its surface.

The body is of a regular form, diminishing insensibly from the
anterior side backwards to the dorsal and anal fins, behind which it
decreases rapidly towards the tail. This latter goes on tapering, then
turns up obliquely, arching itself slightly over the lower lobe of the
caudal. The surface of this caudal prolongation is covered with
small elongated escutcheons, which become the more slender the
more they rise along the caudal arch. They begin above the last
escutcheon Of the lateral row, much resembling the scales of the tail
in Lepidosteus.

The five rows of escutcheons on the' sides of the body and along
the back are scarcely visible, for they are hidden in the thickness
of the body.

The upper lobe of the caudal fin is composed in its whole extent
of spinous rays, generally short and much inclined backwards, di-
minishing in length the more they recede, and becoming rudimen-
tary at their termination. The lower lobe, which gives to the cau-
dal fin its general form, is exclusively composed of articulated and
dichotomous rays. Those of the lower margin, much the largest
and longest, remain undivided for two-thirds of their length ; they
seem even to follow a direction peculiar to them by a slightly con-
cave line. The other rays grow more and more slender the more
they rise above the lobe. They bifurcate first in the middle, and

270 LAKE SUPERIOR.

subsequently several times at a distance which varies for every
ray. The lower lobe of the caudal extends not so far backwards as
the upper. This latter has the form of a very open arch ; the
lower is convex below. The line which joins both extremities is
oblique within the upper half; on the middle line it becomes con-
cave, giving to the posterior margin of this fin the form of an
irregular crescent.

The dorsal fin is equally notched, forming a crescent on its termi-
nal margin. All the rays which compose it are articulated. Those
of the anterior margin, four times longer than those of the posterior,
are arched backwards, undivided through their whole extent. The
other rays dichotomize in the same manner as those of the caudal.

The anal, longer than broad, is placed opposite and somewhat
behind the dorsal. Its form is oblong, the inner and outer margins
are rounded ; the posterior margin is straight, bending slightly
inwards at the middle. The rays are similar to those of the dorsal.
Those of the lower margin being the longest and remaining undivided
through the whole extent ; those of the outer margin dichotomize
like those of the dorsal.

The ventral fins, as broad as they are long, are placed half way
between the pectorals and the anal. Their posterior margin is almost
square, the inner slightly sinuous, the outer rounded. The rays
of the former dichotomize from their basis, those of the latter are
undivided, like those of the other fins.

The pectorals are of all fins the most developed. Their greatest
length is seven inches and a half, and their breadth nearly four inches.
Their form is a rather regular oval, setting aside their margin of inser-
tion, which for two-thirds of its extent, from the outer margin, forms
a straight line, directing itself obliquely towards the interior of the
fin, whilst on the other third we observe a curve which brings the
inner margin of the fin back upon itself. The rays of this margin
become excessively slender, and remain undivided, like those of the
outer margin. Those of the centre dichotomize according to the
common rule.

The number of rays in the fins is as follows : P. 39 to 40 ; D. 34 ;
V. 26 ; A. 23. We may count as many as fifty to sixty on the lower
lobe of the caudal, but they become indistinct beyond this number.

FISHES OF LAKE SUPERIOR. 271

A character common to all fins is to have the outer margin sen-
sibly thicker than the inner, which becomes thin and membranous.
It is also in this outer margin that are found the largest rays,
arched from within outwards, undivided in the greatest part of their
extent, thus giving them a peculiar aspect. Small tubercles are
observed in the outer third of the rays where they are most
dichotomized.

The color is of an uniform blackish brown, which extends to the
fins ; it is a little less intense on the head, on the lower half of the
sides below the middle line it has a yellowish reflection. A pale white
exists over the lower part of the head and the abdomen, as far as
the under surface of the tail.

This species resembles the A. rubicundus of Lesueur, who describes
two varieties of it, one found with the true rubicundus in Lakes
Erie and Ontario ; the other inhabiting the River Ohio. The
descriptions which he has given of them do not enable us to recog-
nize our species in either of these varieties.

ACIPENSER CARBONARIUS, AgaSS.

The general form of this species is rather thick and short than
slender. The back is proportionally very elevated and very convex
from the occiput to the anterior margin of the dorsal fin, from whence
the body begins to grow considerably slender towards the tail, which
last rises obliquely in order to form the higher arch of the caudal
fin. (Plate 5, fig. 1.)

The total length is one foot two inches and a half. The head is
contained three times and a half in this length. The face, from the
anterior margin of the branchial cavity to the extremity of the snout,
equals the fourth part of the length of the trunk. The snout, from
the orifices of the nostrils is contained seven times in this length.

The head itself is depressed, flattened, uniformly inclined from
the occiput beyond the nostrils, where the snout rises considerably,
growing thinner on its margins, which circumstance gives it a convex
form. Seen from above, its shape is that of an elongated triangle.
The upper surface is quite uniform, having only one slight depression
on the middle line, bordered by two small carmee of the frontal and

272 LAKE SUPERIOR.

f

parietal bones. Small plates continue on the snout to its extremity,
and are prolonged on the sides before the nostrils, but do not reach
the lower circumference of the eye. All these bones are covered
with fine granules, disposed in linear rows in the direction of the
head. The eyes occupy the upper region of the face. They are
oval and have their largest diameter longitudinal. They are sur-
rounded with a smooth zone on their lower circumference, limited
above by the bones of the skull, and behind by a bone which sepa-
rates them from the opcrcular apparatus and the branchial cavity.
Another bone, which is triangular, being the continuation of the
preceding, limits the posterior margin of the face and completes the
anterior margin of the branchial cavity. The nostrils, situated in a
depression which is reserved for them before the eyes, open, as is
common, at the surface, by two holes pierced laterally, of which the
upper, the smallest, is subcircular and free, the lower oblong, vertical
and protected by a small membrane at its anterior margin. The small
plates which cover the snout reach not so far as the bone of the
lower angle of the face. The opercular bone is covered with these
fine • granules disposed in striae radiating from the centre. The
membrane which invests it and which shuts the respiratory opening
in front, is covered with a fine rasp, which continues on the sides
of the head to the angle of the mouth. The branchiostegal mem-
brane proper is naked and very thin. It surrounds the opercular
bone from the upper margin of the branchial cavity, and is prolonged
and becomes wider a little above the branchial opening behind the
pectoral fins and beneath the head.

The inferior surface of the head is level, with the snout a little
raised. The mouth opens in a depression behind the eyes. Its
general form is the same as in the A. Icevis, (see pi. 5, f. 2. ;)
it is protractile as in this latter, but the membranous fold which
surrounds the jaws, is smooth on its whole anterior circumference,
where it appears only as a wrinkle surrounding the jaw. It thickens
at the angles of the mouth and terminates in a flattened flap, of
glandular appearance, on the third quarter of the extent of the lower
jaw, leaving the symphysis bare. The palate and the tongue have
sinuous and transverse wrinkles on their surface.

Four thread-like barbels half an inch long, are placed mid-way

FISHES OF LAKE SUPERIOR. 273

between the mouth and the termination of the snout, a little nearer
however to the mouth. On this face, though generally flattened, we
may observe a median longitudinal swelling, having on each side a
depression with widened margins. This skin is bare, although cov-
ered upon its surface with a net of irregular meshes in which we
observe small holes which secrete the mucosity, as in A. Icevis.

The escutcheons of the dorsal row are twelve in number, well de-
veloped, and a rudimentary thirteenth applied to the anterior margin
of the dorsal. They are so near to one another that some are even
slightly imbricated. Their general form is heart-shaped, broader
than long, the two sides limited by a regular denticulated curved
line, rising abruptly so as to form a very sharp median carina,
terminated at the two posterior thirds in a hook, whose point is
turned backwards. Their surface is covered with radiating lines,
owing to the linear arrangement of their tubercles, which are exces-
sively small, and acute. On the space between the posterior mar-
gin of the dorsal and the origin of the caudal we observe three
small plates. The largest is situated on the side of the dorsal, the
two smaller follow immediately and are arranged in pairs. Their
surface is equally covered with small acute tubercles? but the cen
tre is scarcely indicated by a larger tubercle, whence the others
radiate. (See pi. 5, fig. 3.)

The lateral escutcheons are from thirty-two to thirty-three in num-
ber, of irregular oblong form, with the two sides retracted. The
anterior margin is concave, the posterior convex, slightly notched
in the middle. The median carina is but slightly prominent, the
sides of course but little inclined ; the hook which rises above it is
slightly curved backwards ; sometimes it is bifurcated at its point.
The surface, as usual, is covered with small granules in radiating
rows. Their position in relation to the body is oblique from before
backwards. They are less serrated than those of the back, and di-
minish gradually as they approach the tail.

The escutcheons of the abdominal region, from seven to eight in
number, extending over the space contained between the posterior
margin of the pectoral and the anterior margin of the ventral
fins, resemble much in their general outlines those of the back.
Their form is perhaps more rounded, though they do not form a

274 LAKE SUPERIOR.

regular circle. They are quite as much inclined, and their hooka
are stronger, and more arched at the point. The radiating striae
are also more visible.

In front of this double row of escutcheons and as if forming their
immediate continuation on the inner side of the pectoral fins, and
in front of them, we observe a subtriangular bone, the anterior
side of which is concave, bordering the branchial opening beneath.
These two bones are contiguous on their anterior angle, and form
by their reunion a convex curved line along the sides of the mouth,
to which the branchiostegal membrane is attached. A prominent
carina, but unprovided with hooks, extends along the median line
from the posterior angle. A single wrinkle indicates on the middle
of the anterior angle the rudiment of a carina. The striae radiate
from those two centres. The bone of the anterior part of the pecto-
rals and upon which these fins articulate, is small and hidden under
the skin.

An odd elliptical escutcheon with regular outlines is situated in the
middle of the space between the anus and the anal fin. It has a slight
median carina, over which projects an elliptical hook. A rudiment
of an escutcheon leans towards the anterior margin of the anal.

The anus opens in a small depression immediately behind the
ventrals, at a distance of about two-thirds of an inch from their pos-
terior margin, and one inch and three-sixteenths from the anterior
margin of the anal. It is small and surrounded by a cutaneous
membrane, bilobed on the posterior side.

The skin over the whole space which the escutcheons do not
cover is rough to the touch. Small tubercles with acute points
cover uniformly its surface, being every where of equal size
and at an equal distance from each other. On the terminal arch
of the tail they become lengthened and flattened, and invest
the whole space like scales.

The fins are generally small ; the dorsal, broader than it is
high, is triangular with the upper margin concave. It is com-
posed exclusively of soft rays, with the exception of a fulcrum
situated on its anterior margin. The rays are articulated and
subdivided only at their extremity.

The upper lobe of the caudal is formed of small bony rays, short

FISHES OF LAKE SUPERIOR. 275

and strongly inclined backwards, not reaching the extremity of
the fin. The rays of the lower lobe do not differ from those of
the dorsal. They bifurcate like these latter, but at the extremity
only. The posterior margin of this lobe is notched, in the form
of a crescent and elongated in its upper part, along the arch of
the tail. The notch is not deep in the lower part.

The anal is opposite to the dorsal, beyond which it extends
backwards. It is narrow, elongated, almost twice as high as it is
broad. The inner and outer margins are almost straight;, the
terminal oblique margin slightly curved. The rays are slender,
bifurcated at their extremity only.

The ventrals, similar in their form to the anal, are situated at
the posterior third of the body. Their structure has nothing that
distinguishes them from the anal.

The pectorals are as in the A. Icevis the largest of all the fins.
Their form is lengthened, the terminal margin is obliquely rounded,
and passes to the inner margin by an arch. The anterior and outer
margin bears a spinous ray, bent beyond its insertion, and curving
inwards a little before the point. It does not reach the extremity
of the fin. It is flattened in the horizontal diameter of the fin ;
its basis is three-sixteenths of an inch broad and terminates in an
obtuse point, in the margin of the fin. The surface is striated longi-
tudinally on both surfaces, alternating with small furrows and
wrinkles. The soft rays are as in the other fins.

Tbe general color is of a yellowish brown on the upper half
of Jhe body, the yellow growing purer on the sides and beneath
the belly. A large spot of an intense black, and an elongated
quadrangular form occupies, on the middle of the back, the space
between the dorsal and lateral series of shields. A second pair
of large spots of the same color occupies the same position on
the sides of the dorsal fin, on which they even encroach a little.
Other small spots are distributed over the sides of the fish
from the opercular apparatus (itself included) to the tail and
the fins, giving thus to the whole fish a dotted appearance.

276 LAKE SUPERIOR.

The only specimen of this species which is in my possession
was found at Michipicotin on the north-east shore of Lake Superior.

Though this species is very similar in its general characters to
the Acipenser maculosus Lesueur, from the Ohio, we have not,
however, been able to identify it. The description which this au-
thor gives of his species is so vague that he does not even tell
us the form of the fins. The formula of their rays is far from
corresponding with that of our species. Nor is the abdominal series
of plates the same ; those of the sides and back seem to resemble
it more closely. The snout is also more slender; but had not
Lesueur mentioned that the species which he saw is of small size,
we might have supposed that our specimen was the young, which
have generally the snout more pointed than full-grown specimens.

ACIPENSER RHYNCILEUS, Agass.

This species is very similar to the preceding ; it differs from
it only in a few characters which we shall here enumerate briefly.
The body is more slender and diminishes- less abruptly ^towards
the caudal region. The curve of the back is more elliptical;
slightly concave at a small distance behind the head, where the
third escutcheon is sensibly smaller. The head is contained about
four times in the whole length. The face, from the anterior
margin of the branchial cavity, forms the fifth part of the length
of the trunk, and the snout from the nostrils is in the propor-
tions of one to five. The whole length of the fish is nearly twenty-
three inches. The head is slender, elongated, proportionally nar-
row ; its upper surface is very sloping, forming a line feebly broken
at the level of the nostrils. A sinus quite deep, widened on
both sides, extends along the median line of the skull ; narrow
at the top, it widens before it disappears upon the snout. The
frontal and parietal bones are carinated in their middle. The
snout is pointed, but truncated. It is completely covered with
small plates which pass before the nostrils and go to join again
the bone which terminates the lower and posterior angle of the
face. The nostrils open in a bare space which is situated under

FISHES OF LAKE SUPERIOR. 277

the eye. Their form and direction are not quite the same as in
the preceding species.

The shields of the dorsal series are sixteen in number, cordi-
form as in the preceding species, but longer than they are broad,
approaching however more to a circle. The right and left mar-
gins are equally denticulated. An odd plate of medium size is
situated behind the dorsal, and behind this latter a pair of much
smaller plates fill up the remainder of the space to the anterior mar-
gin of the caudal. Both are carinated and provided with a hook.

The lateral series consists of thirty-five pairs of plates, elon-
gated, narrow, irregularly triangular, the most acute point directed
upwards, much resembling those of the preceding species.

The abdominal series has from eight to nine plates, generally
more irregular, more strongly denticulated, with a strong carina
and prominent hook.

The articular bone of the pectoral fin is stronger and more
widened. The pectoral fins themselves are longer and more
rounded on their posterior margin. The anal is also more narrow.
The other fins resemble each other excepting the caudal, which
seems to be less furcated. We have not been able to make a
fuller comparison of the two species, having had only a dried speci-
men of the latter in our possession. The following formula of the
rays is only an approximation, as the fins are somewhat defective.

Very distinct fulcra exist along the anterior margin of all the

ACIPENSER RUPERTIANUS, Richardson.

This species, which we did not find in our excursion, is men-
tioned here only incidentally, for comparison with those which we
have described. Richardson has figured and described it in his
Fauna Boreali-Americana. Our comparisons have been made
upon a skin from Sault St. Mary, for which I am indebted to
Mr. McLeod.

278 LAKE SUPERIOR.

Its head is thicker than it is long, forming one-seventh of the
whole length, which is twenty inches ; the snout is covered with dis-
tinct small plates upon its surface, though it is also granulated. The
frontal sinus is broader than deep, and extends over that part of the
snout which is contiguous to the skull. The dorsal plates, twelve or
thirteen in number, are elliptical ; the lateral series number twenty-
five or twenty-seven, and resemble somewhat those of the preceding
species. The abdominal series have eight or nine plates, longer
than broad, whilst the contrary is the case in the A. rliynchceus, from
the Sault St. Mary. Their circumference is also less. The fins
which we have been able to compare show but slight differences
in the two species.

SlLURID^E.

Whenever we are induced to consider organized beings in
their connection rather than by themselves, we perceive at once
differences between them, which throw more light upon the laws
that regulate their structure, than the most minute investigation of
isolated facts. The Siluridre are fishes which it is difficult to combine
with any other group, unless by far-fetched considerations, and afford
a striking example of the importance of general considerations in the
special study of zoology.

Speaking of the sturgeons above, I have already mentioned their
affinity to the Goniodonts. It is now a matter of great importance to
examine upon what this relation rests, for the systematic position
assigned to that family is also decisive for the Siluridse, which are
very closely allied with the Goniodonts. Indeed, Goniodonts and
Siluridre may be united into one family with almost as much pro-
priety as they can be separated, and wherever one of these groups is
placed, in a general classification of fishes, the other must follow.
That sturgeons belong to the order of Ganoids is now fully ascer-
tained ; but whether the affinity of Goniodonts and sturgeons is suf-
ficient to connect the Siluridre, or whether Siluridse and Goniodonts
are to continue in some connection or other with the many fam-
ilies of Abdominales, with which they have hitherto been combined,
remains to be seen. That the position of the ventrals is not sufficient

FISHES OF LAKE SUPERIOR. 279

to settle this question is plain, as soon as we consider the position of
those fins in the Ganoids, in -which they are also placed at the middle of
the abdomen. The scales which are wanting in most Siluridse, would
apparently seem, at first sight, to afford little information ; let us how-
ever remember that there are some genera among Siluridse, such as
Callichthys and Doras, in which scales of a very peculiar character
exist, and that several other genera have large bony escutcheons
upon their neck. Now these bony plates and scales have the same
structure as the enameled scales of the sturgeons, and their position
in Doras reminds us strongly of the lateral shields of sturgeons ; so
much so, that but for the form of the body, we might be led to con-
sider these fishes as closely related. And really, this affinity is not
altogether superficial ; the development of the jaws and opercular
bones is so imperfect, as to show little analogy to the structure of
those parts in the common Abdominales, whilst it agrees rather closely
to that of the sturgeons. The position of the mouth in Loricaria,
below the snout, is another feature which connects the Goniodonts
and sturgeons, and the genus Scaphirhynchus may be considered as
forming the most natural link between the two families. Again,
Goniodonts have pseudobranchise and a thick membrane encircling
the mouth, which constitute so many more characters connecting them
with the sturgeons ; although these points are of less value than those
already mentioned. I may add, also, that the brain of Siluridse bears
a stronger resemblance to that of the. sturgeons, than to that of any
of the Abdominales ; so that I consider myself justified in referring
the families of Goniodonts and Siluridse to the order of Ganoids,
where they may stand as aberrant families, rather than among the
other great divisions of the class of fishes.

PlMELODUS.

The genus Pimelodus, as characterized by Prof. Valenciennes, in
the Histoire Naturelle des Poissons, seems to me to contain several
distinct types, which might with great propriety be considered as
distinct genera, characterized by their peculiar teeth, the arrange-
ment of their barbels, and the respective position and extent of their
dorsal and anal fins, as well as the form of their caudal. But as the

280 LAKE SUPERIOR.

collections now at my command do not contain sufficient materials to
limit precisely those 'genera, I shall only mention that such a revision
seems desirable, since, as far as I can now judge, the group of
which P. catus may be considered as the type, should constitute a
first germs, and retain the name of Pimelodus, and that new names
should be framed for the other groups of species, of which P. cuclo-
pum, albidus, ctenodus, &c., may be considered as the respective

types.

If we now admit the generic sections, which I propose for
the numerous species of Pimelodus, their study will be by this
very fact much simplified ; for when we have once the group to
which our species belongs, its comparison with the others will be
very easy. Now we have already said that the first group, that
which is to retain the name of Pimelodus, will contain the P.
Catus as its type, and in addition to it the P. punctulatus Cuv. and
Yal., P. coenosus and borealis of Richardson, and P. albidus,
nebidosus and ceneus of Lesueur, besides a new species from Lake
Superior, to be described below. All authors have not admitted
P. ncbnlosus as a species ; the natural history of P. albidus and
ceneus leaves also much to be desired, so it is also with P. punctu-
latus. So that we are still in doubt about the real number of species
which will compose the genus Pimelodus proper. The Pimelodus
Catus, which is perhaps the best known, differs considerably from
our northern species, so that we need hardly mention the differences ;
but P. nebidosus and P. albidus seem to be very closely allied to
P. Catus, if we judge by the description which we have before us.
The P. ceneus would come near P. punctulatus, which in its turn
would remind us of P. Catus. Hence we may see how important
it may be to submit anew these species to a close examination, to study
them each in its locality and by minute anatomical as well as
zoological investigation, to ascertain the value of their characters.

For the present, however, I cannot undertake this comparative
study from want of sufficient materials, but I shall attempt to
describe the species we brought from Lake Superior, and com-
pare it with P. coenosus and borealis of Richardson, from which,
though allied to them, it seems however to differ specifically.

FISHES OF LAKE SUPERIOR. 281

PIMELODUS FELIS, Agass.

The general form is that of most species of the genus, neither
thick, nor elongated. The abdomen is prominent in the space
contained between the branchiostegal apparatus and the ventrals.
The curve of the back rises to the height of the dorsal, whence
it slopes rapidly upon the head. The body is very compressed
from behind the dorsal and ventral fins to the tail. It is com-
pletely bare, with a punctulated appearance, caused by the aqui-
ferous holes w.hich open at the surface of the skin, and which
are especially numerous on the anterior region and on the head.
The lateral line is straight, ascending from the middle of the
caudal to the upper angle of the opercular apparatus. The head,
from the occiput, forms the fifth part of the whole length, whilst
from the posterior margin of the operculum to the end of the snout
it constitutes only one fourth. The head is longer than it is broad,
and forms a regular oval, truncated behind in the occipital region
and elliptical in the anterior circumference. The mouth extends as
far back as the eyes ; the lips surround it under the form of a fleshy,
elastic swelling, in the middle of the jaws only ; but at their reunion
with the angles of the mouth they grow thinner, widen and flatten,
and form a kind of funnel, which enlarges, for a third at least, the
opening of the mouth. The teeth are arranged like those of a
card, and distributed irregularly upon the circumference of the
jaws. They vary in length and size, but are all acute. On the
lower jaw they extend much more backwards in the mouth than on
the upper jaw, where they do not extend beyond the basis of inser-
tion of the maxillary barbels. These latter, two inches long, reach to
the posterior margin of the preoperculum. They follow the upper
circumference of the cutaneous funnel at the angles of the mouth
for the extent of six-eighths of an inch. Hard, horny and flattened
at their basis, they grow gradually softer and more slender towards
their termination. The nostrils are situated on the upper surface of
the head, at a distance of half an inch from the end of the snout.
Their opening, of oblong form, measures one-eighth of an inch in the
direction of the greatest diameter. The barbels which arise from

19

282 LAKE SUPERIOR.

their anterior margin, the smallest of the four pairs, have exactly
the length of the space contained between them and the anterior
extremity of the head. They are soft, flabby and rounded. The
eyes, proportionally small and subcircular, are at a distance of one
inch from the anterior margin of the head. Their diameter is five-
sixteenths of an inch. The four barbels of the lower surface of the
head are placed upon an arc of a circle within the branches of
the jaw. The two internal ones are more distant from each other
than the external ones. These latter are one and one-sixteenth
inches long, whilst the former are only seven-eighths of an inch.
They are soft upon their whole extent, like those of the nostrils,
rounded and elongated.

The opercular apparatus is almost completely hidden under the
skin and the muscles ; a slight swelling indicates the inferoposterior
margin of the operculum. As for the preoperculum, which forms the
anterior outline of the apparatus, we can trace its whole margin,
which is arched within, and upon which the branchiostegal mem-
brane is fixed. The branchiostegal rays themselves are nine in
number ; the first two, the most developed, are of about equal
size, and follow the outline of the preoperculum, without being
attached there otherwise than by the muscles which move them.
All are flattened and concave on their outer surface. The humeral
apophysis, which we perceive through the skin, is strong and robust.
It extends two-thirds the length of the spine of the pectoral fins ;
its outer margin is wrinkled.

The dorsal fin is composed of a spinous and six soft rays. Its
basis measures one and one-eighth inches, the spine is one and
one-half inches long ; the rays of the centre, one and five-eighths
inches. Hence the fin has a quadrilateral form from its in-
sertion to the height of the spinous ray, terminated by an isosce-
les triangle. The spinous ray itself is slender, slightly arched ;
.its posterior margin has neither furrows nor denticulations. At its

* upper third is implanted a rudiment of a soft ray which takes
an oblique direction upwards. The adipose fin is of medium size,
thick at its basis, thin upon its circumference, which extends a little
beyond the posterior margin of the insertion of the anal. It is seven-

- eighths of an inch long. The caudal is subtruncate, almost concave.

FISHES OP LAKE SUPERIOR. 283

It is composed of eighteen articulate, well-developed rays, measuring
two inches along the margins and one and eleven-sixteenths inches in
the middle of the fin, and of six raylets in the upper margin and
ten in the lower margin, hidden in the thickness of the skin. The
anal is high and rounded ; its insertion is two and a half inches
long. It numbers twenty-two rays ; those of the centre are one
and six-eighths inches high. The ventrals, one and three-sixteenths
inches long, are fan-shaped and rounded on their circumference ;
they have eight soft rays. The pectorals have almost the same
form, though less rounded. They are composed of seven soft rays
and one spinous, strong and robust, at whose inner side we remark
denticulations, varying in their number and form, and extending
only along the two upper thirds. The lower third has a carina with
a sharp blade. The length of the soft rays is one and three-eighths
inches ; the length of the spine one and three-sixteenths inches.

The general formula of the rays is as follows : Br. 9 ; D. I. 6 ;
C. 18; A. 22; V. 8; P. I. 7.

Besides the differences in the number of the rays, as we may esti-
mate by the numbers we have given above, this species differs farther
from the P. cosnosus and borealis in the general form of the fins.
Their position upon the body, relatively to each other, affords not less
sensible differences when we compare the measures which Dr. Rich-
ardson gives for his P. coenosus, setting aside the difference of size
of our specimen, which had two inches more for its whole length.
Similar differences are remarked between our P. Felis and the P.
borealis, though for this latter we have not been able to make our
comparisons upon positive numbers, the celebrated author having
neglected to give the numbers of the rays of this species. The pro-
portions and the dimensions of the head are also far from agreeing,
being in the P. coenosus two-ninths of the whole length, and in
the P. borealis as broad as long, whilst we have seen, that in our
species its length forms the fourth part of the whole length, and
that besides, it is much longer than broad. The spinous ray of the
dorsal is more feeble than in P. coenosus, and, besides, unprovided
with the deep groove in which the soft ray of this fin is lodged. The
spinous ray of the anterior margin of the pectorals, which in P.
borealis is unprovided with denticulations on its posterior margin,

284 LAKE SUPERIOR.

is, on the contrary, in our species, provided with such serratures as
is the case in P. coenosus.

Such are the principal features upon which the comparison may
rest, while good figures are yet wanting. The differences which we
have indicated, however slight they be, do not allow us to identify
our species with the one or the other of those mentioned above.
The comparison of original specimens would be necessary in order
to fix in a sure manner the traits of resemblance, or the differential
characters of each of them.

PERCOPSIS, Agass.

In order fully to understand and perfectly to appreciate the char-
acters of this genus, and the interest involved in its discovery, it is
necessary to remember various relations of the different types of the
whole class, which however do not constitute generic distinctions,
although they bear upon the peculiarities of this new type.

In the first place, it is a matter of no little importance that,
' among the fishes of former ages, we find every where types which dif-
fer widely from the forms of our time, and that those forms are the
more different, as they belong to older geological deposits. The
differences are even so great, that out of the four orders of this class,
there are only two which constitute the fauna of fishes in the older
formations ; two orders, which in our day are comparatively re-
duced, I mean the Placoids and Ganoids. Moreover, the types are
peculiar in all epochs. For instance, the sharks of former days, espe-
cially those of older epochs, resemble solely that curious genus of
Port Jackson, New Holland, the Cestracion, which is so remarkable
among the living fishes as to form a group by itself. The Ganoids, of
which there are so remarkably few in the present creation, such as
the gar-pike (Lepidosteus) of this continent, are not less peculiar,
and in connection with those ancient Placoids, constitute the only rep-
resentatives of the class of fishes throughout the earlier geological
ages down to the deposits of the chalk, when new families of other
orders, the Ctenoids and Cycloids, begin to make their appearance,
preparatory as it were to the present development of that class, and
are successively diversified with the modified adaptations of the whole

FISHES OF LAKE SUPERIOR. 285

class. Now the genus Percopsis is as important to the understanding
of the modern types of fishes as Lepidosteus and Cestracion are to
the understanding of the ancient ones, as it combines characters which
in our day are never found together in the same family of fishes, but
which in more recent geological ages constituted a striking peculiar-
ity of the whole class. My Percopsis is really such an old-fashioned
fish, as it shows peculiarities which occur simultaneously in the fossil
fishes of the chalk epoch, which however soon diverge into distinct
families in the tertiary period, never to be combined again.

This ancient character of some of the American fishes agrees
most remarkably with the peculiarity of the vegetation of this conti-
nent, which, as I have shown on former occasions, resembles also
the fossil plants of prior ages.

The geographical range of these peculiar, old-fashioned beings is
also very remarkable, they living in temperate, or rather cold climates,
when their earlier representatives lived in warmer epochs.

The most striking features of the fishes of the tertiary period and
those of our time consist in their belonging to two groups of the class
only ; one, the Ctenoids, with rough, combed scales, in which the re-
spective representatives have also prominent serratures on prominent
spines upon the head, in the operculum in particular, and in the fins ;
the other, the Cycloids, smooth, with simple scales with an entire
margin, in which some few types however have also spinous fins.

Now my new genus, Percopsis, is just intermediate between
Ctenoids and Cycloids ; it is, what an ichthyologist, at present,
would scarcely think possible, a true intermediate type between
Percoids and Salmonidge.

The general form of this genus reminds us of the common perches,
but it is easily distinguished from them, by the fact that its head and
the opercular apparatus are smooth and unprovided with denticula-
tions, as also by the presence of a small adipose fin, as in the salmons.
The anterior dorsal is also a small fin, composed of soft branched ar-
ticulated rays, as in the salmons. The ventral fins are placed at
the middle of the abdominal cavity, as in the Abdominales in general.
The scales, however, are truly serrated as in the Percoids, a struc-
ture which, as far I know, does not occur in any of the Abdominales.
The conformation of the mouth is also as in . the perches, that is to

286 LAKE SUPERIOR.

say, the intermaxillaries form alone the upper margin of the mouth,
and the maxillaries stand behind as a second arch, but the vomer and
palate are entirely destitute of teeth.

This fish, of which I shall publish a full anatomy, should be consid-
ered as the type of a distinct family, under the name of Peroopsides.

PERCOPSIS GUTTATUS, Agass.

PI. L, fig. 1 and 2.

This is a fish of small size and slender form, though the back is
very much elevated. Its greatest elevation corresponds to the an-
terior part of the dorsal fin, that is to say, a little nearer the end of
the snout than the insertion of the caudal. The tail is proportionally
elongated, a little compressed between the adipose fin and the basis
of the caudal. The sides are compressed, and diminish gradually in
thickness from the front backwards. The ventral line is less promi-
nent than that of the back ; it rises more backwards of the anal, to
concur in the contraction of the tail. The profile of the head, which
is small and compressed like the sides, is regularly conical; the
length of the head is contained three times in that of the body, set-
ting aside the lobes of the caudal.

The eyes are large and circular, situated near the upper margin
of the face ; if a vertical line passed through their centre, it would
divide the head into equal parts. The space which separates the
anterior margin of the orbits from the end of the snout, is about half
an inch. The nostrils open outwards by a double opening, and are
very near the eyes. One of these openings has the form of a cres-
cent, whose convexity is turned towards the eye ; the other is small,
subcircular and situated in the concave space of the preceding.
(Fig. 2.) The mouth is small, and appears scarcely larger when
opened ; the upper jaw extends beyond the lower, and is formed solely
by the intermaxillaries, upon which we remark a narrow band of
small, excessively fine teeth, arranged like the teeth of a card. The
palate is entirely smooth. On the contrary the pharyngeans are
covered with similar teeth still more slender, as also the oesophagean

FISHES OF LAKE SUPERIOR. 287

shields. On the lower jaw there is a narrow band of teeth, like
those of the intermaxillaries. The labials extend a little beyond the
intermaxillary to form the angle of the mouth, which corresponds to
a vertical line which would pass before the nasal openings. The
suborbital bones are very much developed. They are four in number,
intimately united, extending from the posterior and lower margin of
the eye to the nostrils. The three first, much the smallest, occupy
the lower circumference of the orbit ; the fourth, almost as large as
the three others together, is the strongest and the most robust and
protects the lower margin of the nostrils ; it sends out a prominent
point to the space situated between these latter and the eye.

The opercular apparatus is completely smooth, like the surface of
the head itself. The posterior free margins of the bones which com-
pose it, are destitute of any kind of spines or denticulation. The
most developed, and at the same time the most robust of the bones
of this apparatus, is the preoperculum, which occupies almost the
whole width of the face. Its form is triangular ; the outer margin of
its ascending branch is slightly concave ; the lower branch, the most
developed, is straight and encircles the lower margin of the face.
The operculum is quadrilateral, its four angles are prominent ; its
upper, hinder and lower borders are notched or concave, its anterior
margin is almost straight. The suboperculum, small, narrow,
oblong, is lodged in the concavity of the lower margin of the opercu-
lum. The interoperculum, which is a third longer than the suboper-
culum and which it resembles in form, is entirely hidden under the
lower branch of the preoperculum. The branchial openings are very
large ; they continue to the middle of the lower surface of the head,
where they are almost contiguous. The branchiostegal membrane is
supported by six curved ra}Ts ; the upper ones, which are the largest,
are flattened. There are four branchial arches on whose inner border
we remark a double row of shields in relief, covered with small card-
like teeth, as we observe on the phai'yngeans.

The disposition of the fins is in striking harmony with the form of
the fish. The dorsal, which is the largest, is situated at the middle
of the back. Its length equals the height of its anterior margin,
being more than twice as high as its hinder margin. The upper
margin is straight. There are twelve rays. The two first are short

288 LAKE SUPERIOR.

and spinous, close together; the third, or first of the soft and. articu-
lated rays, is the largest. These latter bifurcate at the middle of
their height ; every bifurcation subdivides again at its extremity. A
small adipose fin is situated at about equal distance between the pos-
terior margin of the dorsal and the basis of the caudal. The caudal
is furcated ; it has eighteen rays, of which the longest are subdivided
three times at their terminal extremity. The anal is situated behind
the dorsal. This is a small fin, higher than it is long, with regular
and straight margins, composed of eight rays, of which the first,
shorter and more slender than the other, is undivided. The second
and eighth bifurcate only once, the five middle ones branch so far as
to show divisions of the third order. The ventrals are placed per-
pendicularly to the anterior margin of the dorsal, narrow at their
basis ; they soon widen to become oval with a regularly rounded
circumference. There are eight rays ; the four of the centre
thrice subdivided, those of the margins twice only, the first being
simple. The pectorals arise at a small distance from the branch-
ial opening and occupy almost all the lower part of the body.
They are elongated, oval, composed of twelve very slender thread-
like rays, subdivided thrice at least at the centre of the fin, the first
being simple. Its extremity reaches almost the middle of the dorsal.

Br. 6 ; D. 2. 10 ; A. I, 7 ; C. 8, 18$ ; V. 8 ; P. 12.

The scales are large in proportion to the size of the fish. They
are little imbricated and of about equal size on the whole surface of
the body except under the throat, where they are a little smaller
and subcircular. On the sides their height is greater than their
breadth. The anterior margin is rounded ; their hinder margin
forms a very obtuse angle, and under the microscope it exhibits a
row of small needles, somewhat distant, and which seem to be im-
planted in this margin instead of appearing as serratures. This
type of scales comes near to that of my Corniger spinosns, and to
some genera of the cretaceous epoch. The concentric striae are very
distinct, but I could not perceive any radiating strios.

The lateral line, nearer to the back than to the belly, extends
from the upper angle of the operculum, arches slightly upwards
towards the dorsal fin, and then descends again insensibly to the
middle of the tail, to terminate at the centre of its peduncle.

FISHES OF LAKE SUPERIOR. 289

The ground color is of a yellow, violaceous tint, much dark-
er above the lateral line than below. The back is spread with
blackish brown spots, sometimes disposed in two longitudinal rows,
sometimes in three, however without great regularity. On the
middle of the body extends a silvery ridge tapering slightly from the
head to the basis of. the caudal. It is not rare to see sometimes
blackish spots encroach upon this bright band. The fins are uni-
colored, and of a transparent whitish tint like that of the abdomen.

We found this fish in great abundance at the Sault St. Mary, at
Michipicotin and at Fort William.

PERCOIDS.

Whenever we compare the fishes which occur in a given locality,
we are struck with peculiar associations entirely different from those
which we may find in other localities. Take the Bay of Massachu-
setts, for instance, where we have sharks, skates, &c., &c., combined
together in numeric proportions, and represented by species alto-
gether different from those which occur on the shores of the Middle
States or around Florida and in the Gulf of Mexico. Again, if we
compare freshwater fishes, as they occur in any extensive hydro-
graphic basin, for instance, those in the Canadian lakes, or in the Ohio
and Mississippi, or those of the lakes and rivers of Europe, with the
marine faunas, we find still more striking differences. Entire families
common in the sea under the same latitudes have no representative
in fresh water ; there are no sharks and no skates, no flounders, soles
or turbots, no mackerels, no herrings, as permanent inhabitants of
the freshwaters in the latitudes above mentioned ; so that a collec-
tion of species from the freshwater or from the sea, even if all
the species were to be new, could be recognized by an ichthyologist
as derived either from the ocean or from some inland water.
However different such associations of marine and freshwater
species may be, there is nevertheless scarcely any family, whether
generally marine or fluviatile, in which there is not some species
living in the other element. There are some families again,
in which the proportions between marine and fluviatile species are

290 LAKE SUPERIOR.

about equal, and there are still others in which the individuals of
the same species are alternately at different seasons of the year either
marine or fluviatile ; this is particularly the case with such as ascend
from the sea into the rivers at the spawning season, to deposit their
eggs in waters more genial to the growth of their young than those
in which they are mainly to live when full-grown.

Percoids belong to those families of which there are certain pro-
portions of strictly freshwater, and certain proportions of strictly
marine genera, the number of marine species being however much
greater than that of the freshwater ones, and very few of the species
having the power of enduring both the freshwater and the sea.

That the family of Percoids, as it is now circumscribed, is in
the main a most natural group, cannot be doubted, especially if
we remove from it such genera as Trachinus, Uranoscopus, Sphy-
raena and a few others ; there remains however a question, not to be
decided here, how far Sparoids and Sciaenoids should be considered
as distinct. Indeed, at different times, in two editions of the same
work, Cuvier in his Animal Kingdom has successively associated
them in one great family, and divided them into two distinct groups.
The fact is that these fishes are closely related, and it is for future
investigations to determine the value of those characters upon
which the distinction rests, which consists only in the serrature of the
opercular apparatus, the presence or absence of teeth upon the
palatine bones, and the degree of development of the so-called
mucous canals in the head, characters which have not even been
strictly adhered to in the arrangement of individual genera.

Whatever may be their closer or more remote affinities, the
Percoids of the Canadian lakes, as well as those of the other fresh
•waters of North America, are much more diversified than those of
the freshwaters under similar latitudes in the Old World. This
is not the case with Lake Superior itself, for, on the contrary, that
lake furnishes but few true Percoids ; but the other great lakes teem
with a variety of genera and species of that family, which among
themselves, as well as with reference to the common type of the
whole family, differ much more from the Percoids than those of
Europe ; I need only mention the genera Pomotis, Centrarchus,

FISHES OF LAKE SUPERIOR. 291

and Huro or Grystes, which all occur in the lower lakes, to show
that this is the case ; and at the same time to indicate the great dif-
ference there is between the fishes of the upper lakes and those of
the lower.

A comparative list of the Percoids of the two regions will show
better than words, that notwithstanding the free passage there is
between all these waters, notwithstanding the great similarity
between the waters themselves, there is an organic difference
between the ichthyological faunae of the two regions.

This list shows not only the great difference there is between the
fishes of the upper and lower lakes, but also how closely the ichthy-
ological fauna of Lake Superior resembles that of northern Europe,
where the same genera of Percoids have representatives as in the
north of this continent, a fact which goes farther to show how much
more uniform the fauna of the north is than even the fauna of the
temperate zone.

Closely resembling the European species, the yellow perch of
America differs however considerably from it, so that no naturalist
after Cuvier, who first distinguished them from each other, has ever
thought to identify them. Its several varieties, described first under
particular names, seemed then to constitute species quite as distinct
from each other as the Perca flavescens is from the Perca fluvi-
atilis. But at that epoch, when the principle of the constancy or per-
manence of species had just been placed upon an anatomical foun-
dation, naturalists for a time lost sight of this other fact, that the
species common to a fauna are subject to individual variations which
run over the whole range of the species. To study these changes,
to bring back every variation to its true type, to trace the circle of
the species through so many oscillations, was a task whose results
could not be anticipated. The principle of the permanence of
species has remained in our science as a well-ascertained fact, but
naturalists have found that many which had been distinguished
as species had to be cancelled as soon as their characters were better
understood. Thus, in a series of more than forty individuals of
the yellow perch of America, we can no longer trace the limits of
separation between the Perca granulata, serrato granulata, acuta
and gracilis, which all belong as mere varieties to the P. flavescens,
as Dr. Storer has already determined. A more pointed snout, a
more slender form, a more wrinkled head, more marked wrinkles
on the operculum, and the denticulation of the opercular bones,
are not constant characters, any more than the color, or the number
of the transverse bands, which vary with the age of the individual.
We have examined perches from the Sault St. Mary, from Fort

William, from the Pic, and from Lake Huron ; we have compared
them with specimens from Massachusetts, New York, and Pennsyl-
vania ; we have compared again and again all their different charac-
ters, and we have seen that the same variations occur in all these
supposed species. No difference in the form and relative position
of the fins could be noticed ; the same arrangement and aspect of
the scales characterizes them all. The comparison which we have
thus been enabled to make of these different varieties confirms their
specific identity. No appreciable difference exists ; there are the
same crests, the same cavities and sinuosities of the bones of the
head, and the same proportions between their different parts.

I have been able to secure only a few specimens of this species
from Lake Huron, about four inches long. By means of comparisons
which I have made of specimens from Massachusetts, New Y7ork,
and Pennsylvania, I have nevertheless been able to ascertain its
identity. For more ample details upon this fish I refer to the works
quoted above, in which the species is described and figured. I must
however remark that I have only mentioned in the synonymy those
authors with whose species there remains no doubt in my mind,
since I am satisfied that the so-called Pornotis vulgaris of the South-
ern States is not the same species. In order to avoid all confusion,
I have left out those synonyms which I was not able to verify di-
rectly, quoting only authors who have given minute characters and
good figures.

The Pomotis vulgaris has been quoted as found in almost the
whole extent of the United States. We are sure that it inhabits
the Great Canadian Lakes, and the Northern and Central States
of the Union. We do not know its western limit, though it is
quoted as found in Ohio. Our specimens are from Lake Huron.

This fish has about the same geographical distribution as the
Perca flavescens northward, but it does not extend so far south. It
occurs however in all the great Canadian lakes, and throughout the
State of New York and parts of Ohio. It remains still to be
ascertained, whether the Okow or Hornfish* belongs or not to the
same species.

I do not believe that the L. canadensis of Hamilton Smith is
even specifically distinct from the L. americana, though its author
is disposed to view it as a new generic type, because of the pres-
ence of five spines on the margin of the operculum, and of the
absence of denticulations on the bones of this apparatus. I am
satisfied that these opercular spines lose much of their value in this
genus. Indeed in two specimens of L. americana which I pro-
cured about Lake Superior, I have seen that one of them had
two small points on the hinder margin of the operculum of the left
side only, whilst there was no trace on the right side. The hinder
point of the operculum was itself very acute and resembled a third
spine a little more robust than the two others. The specimen
measured thirteen inches. In a specimen from Lake Michigan,
twenty-two inches long, for which I am indebted to Samuel C.
Clarke, Esq., of Chicago, the operculum of the left side has equally
two spines on its hinder margin, and two very near each other on
its upper angle. On the right side there is a single spine observa-
ble, but more robust, though very short like the others, and on the
upper angle two of equal development.

As for the other bones of the opercular apparatus, the following
is what we have observed in other specimens from Lake Superior, as

* Richards. Fn. Bor. Amer. III., 14.

FISHES OF LAKE SUPERIOK. 295

•

also in those of Michigan : the preoperculum is denticulated on its
whole circumference ; the interoperculum and the suboperculum are
equally crenulated or denticulated towards their union, upon the
third part at least of their extent. The lower margin of the sub-
operculum is undulated. The suprascapular bone has fine serra-
tures ; the scapular and the humeral are entire. According to Dr.
Richardson the crenatures of the margin of the interoperculum
are scarcely perceptible, and the suboperculum smooth and straight.
The suprascapular should be smooth, like the scapular and humeral,
whilst the figure of the Histoire Naturelle des Poissons represents
these three latter bones as serrated. This shows great variations in
these parts.

The following is the formula for the rays of the fins, as we
counted them in our specimens :

When this fish is young, until it reaches a length of three to four
inches, the head resembles still more that of the pike than when full-
grown, the snout being then very depressed ; but the teeth are all
uniform. However, even at this epoch, the whole of its physiog-
nomy reminds us so much of the species described above that we
could not hesitate an instant for its determination. The black mar-
blings stand out more distinctly from the ground of the color than
in the full-grown ; they unite in groups and constitute irregular and
vertical zones. Dr. Dekay's Lucioperca c/risea is also founded upon
young specimens of the common pike-perch.

This species is very closely allied to the G-rystes salmoides of the
Southern States,* from which it is however distinguished by the
profile of the more raised back, and of course by a broader body.
The surface of the skull is uniformly rounded and not depressed as
as in G-. salmoides. The proportions of the head compared with
the body are the .same as in this latter, but the mouth is less opened
and the shorter labials do not reach a vertical line drawn across the
hinder margin of the orbits, whilst they exceed such a line in 6r.
salmoides. The teeth are arranged like cards, and are similar in
both species.

The fins upon the whole seem to be cut on the same pattern as in
6r. salmoides, but when we examine them attentively we see that
they are all stabbed like the body itself, the ventrals and pectorals
shorter and more widened, the dorsal and anal lower. As for the
other details of their structure they are about the same, as we may
see from the following formula.

Br. 6 ; D. X. 14 ; A." Ill, 10 ; C. 7, I, 8, 7, 1, 6 ; V. 1, 5 ;
P. 16.

The scales are a little smaller, but of the same form as in 6r.
salmoides; the radiating struie are perhaps less marked. They
cover the opercular apparatus and the cheeks, but at this latter
place their smaller size is quite remarkable ; this latter character
is very striking when we compare both species.

Our specimens are from Lake Huron ; one of them measures
twelve inches, and the other seven. I have also received two speci-
mens from Lake Michigan, through the care of Mr. Samuel C.
Clarke, the largest of which measures eighteen inches. Professor
Baird forwarded to me specimens from Lake Champlain. Dr. De-
kay has found it in Lake Oneida. Finally, this species extends
to Pennsylvania, as I was able to convince myself by two speci-
mens collected at Toxburg, and for which I am under obligation to
Professor Baird.

* Grystes salmoneiis does not occur in the Northern nor in the Middle States, al-
though Dr. Dekay mentions it upon the authority of Cuvier, who probably mistook
specimens of our Grystes fasciatus for the southern species. Having, however, failed
to discover this confusion, Dr. Dekay describes the same fish again, under the name of
Centrarchus obscurus.

FISHES OF LAKE SttPERIOR. 297

HURO NIGRICANS Cuv. is another species of the lower Canadian
lakes, which occurs also in Lake Champlain. The generic dis-
tinction from Grystes, does not, however, rest upon sufficient charac-
ters to warrant its preservation in the system of fishes ; I shall
therefore call it in future Crrystes nigricans. It is a very common
fish in some of the lakes, and highly esteemed as an article of food.
Throughout the lake region it is known under the name of black
bass , and may be seen in large numbers in the enclosure under the
gallery of the Cataract Hotel at Niagara. Dr. Dekay describes it
as Centrarckus fasciatus, although he copies also Cuvier's description
and figure of Huro nigricans, but without perceiving their identity.

In the northern lakes there is only one species of true Centrarchus
found, the Centrarchus ceneus; but it does not occur as far north as
Lake Superior, though it is common in Lake Huron and the other
great lakes.

COTTOIDS.

As they have been circumscribed by Cuvier, the Cottoids consti-
tute a most natural family, though they contain genera apparently
widely distinct. Indeed, between Peristedium and Scorpsena,
between Pterois and Aspredophorus, between Gasterosteus and
Cottus, there seems to be as great a chasm as can exist in a
natural family ; however, they all belong to one and the same
natural group. P>ut in order to be satisfied that it is so, one should be
acquainted with the fact, that animals or plants belonging to one and
the same natural division, will in certain cases resemble each other
so closely as scarcely to allow distinct subdivisions, as, for instance,
the Siluridae, which, with the same features throughout so numerous
a family, run into various extremes of form, in which, however,
there is no mistaking the family likeness even in the external ap-
pearance ; the same is also the case among Cyprinidte or among
Eels. But there are others, whose relations rest upon one particular
combination of characters, which will, nevertheless, assume very
different features, though preserving throughout that common trait of
character. Genera belonging to such families may sometimes at
first sight have very little resemblance to each other, they may

20

298 LAKE SUPERIOR.

differ in very different amounts of variation, and nevertheless con-
stitute, at least in the eye of the deeper investigator, a very natural
group ; such, for instance, is the family of Cottoids, such again is
the family of Scomberoids. The difficulty in such cases is not the
diversity, but a correct appreciation of the connecting character,
which, if misunderstood, might bring together animals widely dis-
tinct in structure, but apparently related by external appearance ; for
instance, the genus Capros among Scomberoids, near Zeus, owing to
its form and the dilat ability of the mouth, when in truth it belongs
to the Chretodonts, in the vicinity of Chelmo.

Taking for granted that the family of Cottoids, as it is now charac-
terized, is in the main a natural one, the question arises at once,
what can be done to appreciate correctly the true relations of those
remarkable tropical forms, as Pterois, Lynanceia, &c., with the
more uniform Cottus, Etheostoma, Gasterosteus, of the freshwaters
of temperate regions ? To become satisfied that they are truly
members of the same family, it is necessary to undertake an extensive
comparison of the structure of their head, and especially of the ar-
rangement of their infraorbital bones, when it is seen that frequently
the particular development which characterizes, generally, this
group, is reduced to a rudimentary state in some of its members, as
in Etheostoma and the genera allied to it. This group of small
Cottoids having attracted less attention than the larger marine types,
we subjoin a synopsis of their genera.

COTTUS.

A broad and depressed "head, contiguous to a body gradually
diminishing towards the tail, is the essential zoological character of
the genus Cottus, which contains at the same time freshwater and
marine species ; the former having, as the character of the group, a
head generally smoother and less prickly with spines than the
marine species, which in their turn are generally larger.

Europe as well as America produces species of both groups.
For a long time all freshwater Cotti of central and northern Europe
were considered as identical with Cottus Grobio, when, twelve years
ago, Mr. Heckel * distinguished several species, very similar, it is
true, to Cottus Grobio, but differing, however, in many respects.

Recently, an American naturalist has attempted to show that all
Cotti of Northern America constitute only a single species, and
that this species is identical with the Cottus Grobio of Europe.
However, studying the Cotti which we have collected around Lake
Superior, I first recognized two species ; then comparing them with
the C. cognatus Richards, and the C. viscosus Hald., I found these
two latter not only distinct from each other, contrary to the
opinion of Mr. Ayres, but yet distinct from those of Lake Superior.
So that the presence of C. Grobio in this continent is quite illusive,
as also the supposed identity of the Cotti in different regions.

A monograph of the freshwater species of the genus Cottus in
Northern America would be a work of very great importance, were its
purpose but to rectify the different opinions entertained with regard
to them.

COTTUS RICHARDSONI, Agass.

The largest individuals of this species which we have had at our
disposal, and on which our description rests, measure four and three-
fourths inches with the caudal. The head alone constitutes one
and one-fourth inches of this length, of course a little more than the
fourth part ; its breadth equals three-fourths of its length, and its

•Annalen des "Wiener Museums, 1837, II.

FISHES OF LAKE SUPERIOR. 301

height forms a little more than the half. Besides being very
depressed and flattened, the head farther presents a slight depression
on the occiput. The mouth is large, its breadth measures nearly six-
eighths of an inch. The jaws are of equal length, bordered with
excessively fine teeth, with very hooked points. The upper jaw is
slightly protractile. The lips are considerably developed and form
a very marked rounded process, on both sides of the lower jaw.
The eyes of a circular form, with a diameter which exceeds a quar-
ter of an inch, are placed at a distance of three-eighths of an inch
from the end of the snout. The nostrils occupy about the middle of
this space. The spine of the preoperculum scarcely forms a pro-
jection through the skin ; it is strongly bent upwards and back-
wards. The upper and hinder angles of the operculum terminate
in a small process, flat and sharp, which remains hidden in the
thickness of the membrane which encircles the free margin of this
bone. The branchiostegal rays, six in number, on each side, are
slender and cylindrical. The isthmus between the horns of the
hyoid bone measures half an inch.

The form of the body is regular, gradually decreasing towards the
tail. The line of the back is raised ; that of the belly is about
straight, forming the continuation to the flattening of the lower sur-
face of the head. The greatest height corresponds to the anterior
margin of the first dorsal fin ; it measures three-fourths of an
inch, whilst the transversal diameter of that same region measures
nearly six-eighths of an inch. Above the tail the height is but five-
sixteenths of an inch, and the thickness one-eighth. The tail itself is
slightly dilated and rounded at the insertion of the caudal.

The fins upon the whole are much developed. The first dorsal
has a basis of six-eighths of an inch, and is five-sixteenths of an inch
high, and is situated at one and three-eighth inches from the end of
the snout. Its upper margin is rounded, the rays of the centre
being the longest ; they are eight in number and undivided. The
second dorsal, twice as long as the first, and one third higher, is
composed of eighteen rays, the longest occupying the centre of the
fin ; a single one of them is dichotomized at its upper end. The
caudal, about six-eighths of an inch long, is truncated behind. Its
upper and lower margins are slightly rounded. Thirteen rays may

302 LAKE SUPERIOR.

be counted there with a few rudiments ; the four rays of the centre,
bifurcated from the middle of their length, dichotomize anew at
their extremity jointly with the two adjacent rays above and below.
The anal begins beneath the third ray of the second dorsal and
terminates a little before this latter ; its form as well as its height
is about the same ; there are fourteen undivided rays in it. The
ventrals contain five simple- rays ; the first, intimately connected with
the second, is a little shorter. Their length is about five-eighths of an
inch. The pectorals are large and fan-like ; the rays, fifteen in num-
ber, are all undivided ; the longest occupy the upper third part of
the fin. They are only three-fourths of an inchlong, of course much
below the length of the head.

Br. 6 ; D. viii.-18 ; C. 3-13.1 ; A. 14 ; V. I. 4 ; P. 15.

The anus is situated exactly in the middle of the length, including
the caudal, which places it nearer to the insertion of this fin than
to the end of the snout ; it is bordered behind by a small, tri-
angular, membranous appendage which leans towards the anterior
margin of the anal. The body is completely naked and unprovided
with scales, as is the case in all species. The lateral line is very
distinct, it begins at the upper margin of the operculum, bends
slightly downwards, then rises to terminate in a straight line about
the middle of the second dorsal after having considerably approached
the back. A row of pores is arranged in a straight line, constantly
ascending until they are confounded with the back at the hinder
margin of the second dorsal, at a distance of three-eighths of an inch
from the insertion of the caudal.

The color is a dark olive-colored brown on the whole surface of
the head and cheeks and all along the back. The lower half of
the sides is of a lighter tint. The abdomen and the lower face of
the head have a rather yellowish tint, dotted with very small black
spots. The lower jaw is sometimes completely black. The general
tint of the fins is the same as that part of the body to which they cor-
respond. The dorsals, caudal,anal and pectorals are barred trans-
versely with blackish spots. The ventrals have the same shade as
the abdomen.

The characters which distinguish this species from C. cognatus
Richardson, are easily made out by comparing the description which

FISHES OF LAKE SUPERIOR. 303

that author gives of it. The more distant position of the anus ; the
proportions in the dimensions of the head and body ; the lateral
line which terminates before the extremity of the tail ; the more
anterior position of the anal relatively to the second dorsal, and
finally the shorter pectorals in proportion to the length of the
head, are the most striking peculiarities.

I have found several specimens of this species in Montreal
River. Among the number was one, whose general form has the
same aspect, the same tint, the same proportions of the head and
body, the same form and structure of the fins, the same mouth, but
whose palatine bones bear a small group of teeth like those of the
vomer. As yet we know only one freshwater species with palatine
teeth, the O. asper Rich. From among five other specimens, also
from Lake Superior, from Isle Royale, for which I am under obligation
to Dr. C. T. Jackson, I have found the same group of palatine teeth
in the largest of them, so that I am inclined to consider this peculiar-
ity as an indication of old age, rather than a specific character.

COTTUS FRANKLINI, Agass.

This species is distinguished from the preceding by the following
characters : the head retains the same proportions relatively to the
body, but the mouth is smaller and less opened, and the teeth are less
strong. The body diminishes more abruptly in height beyond the
anus, and in its whole length the thickness is proportionally greater.
Thence there results a more cylindrical and subconical form. The
lateral line is less approximated to the back ; it disappears on the
sides as in the preceding species, but the row of pores continues as
far as above the middle of the insertion of the caudal after a very
abrupt depression a little before its termination.

The fins are less developed, but their relative position is the same.
The ventrals instead of five rays have only four. The caudal rays
alone bifurcate once on the middle of their length. In all other
fins they are undivided. They may be reduced to a formula as
follows :

Br. 8 ; D. 8-17 ; A., 12 ; C. 1-12.2 ; V. 1-3 ; P. 14.

The membranous appendage of the posterior margin of the anus is

here only in a rudimentary state, but the position of this orifice is the
same as in the preceding species, and this fact excludes, a priori, the
idea of an approach to the C. cognatus of Richardson. Farther,
our species has only four rays in the ventrals and twelve in the
anal.

The ground is of a yellow olive color with black spots. The
lower side of the head and body and the lower half of the sides are
yellowish white. The fins have the color of the region of the body
to which they correspond. The ventrals and anal are of one color,
the others are barred or simply spotted in transverse rows.

This species is not without some analogy to that of Pennsyl-
vania. The comparison which I have been enabled to make with it
by means of specimens, for which I am under obligation to Professor
Baird, has shown me differences which I consider as specific.

Found in various localities along the eastern shores of Lake
Superior. Prof. James Hall has also sent me specimens collected
by him on the southern shores of the same lake.

BOLEOSOMA, Dekay.

This genus has been instituted by Dr. Dekay for a small fresh-
water fish of the State of New York. He placed it in the family of
Percoids, whence we withdraw it, to associate it to the Etheosto-
mata, which should constitute a distinct group among the Cottoids,
and the Gasterostei another near them. The zoological characters
of this genus may be formulated in the following manner : The form
of the body is that of a dart ; the head is very short, rounded like an
arc of a circle, below which the mouth, generally small and slightly
protractile, opens horizontally ; the upper jaw sloping over the lower.
The neck and the sides of the skull compressed. The opercular
apparatus and the cheeks covered with scales.

The species known to me are : the Boleosoma tessellatum Dekay,
the B. maculatum of Lake Superior, the Etheostoma Olmstedi of
Pennsylvania and the Northern States, which belongs to this genus
and not to Etheostoma proper, and a species from South Carolina
which I have called Boleosoma tenue. •

FISHES OF LAKE SUPERIOK. 805

BOLEOSOMA MACULATUM, Agass.

Plate IV., fig. 3.

The general form of this species is slender. The largest specimens
which we have studied measured two and three-eighths inches in their
whole length. The occiput and the anterior region of the body, before
the first dorsal fin, are sensibly depressed. The space which the
dorsal fins occupy forms a slightly convex line, sloping backwards
and rising again behind the posterior margin of the soft dorsal and
before the origin of the caudal. The ventral line is almost straight ;
it becomes convex beneath the tail in the same proportion as that of
the back is concave. If we add to that a gradual compression of
the sides from the front backwards, we shall have for the whole body
an oval form, whichsoever be the region upon which we make a
transverse section. We shall remark only a gradual decrease of the
oval from the head towards the tail.

The head is short and thick ; it forms just the fifth part of the
whole length, measured from the end of the snout, to the posterior
margin of the operculum. The snout grows rounded under the form
of an arc of a circle, beneath which the upper jaw is fixed horizon-
tally. It is about semi-elliptical and slopes over the lower jaw on
its whole circumference. The latter, by the third part more
narrow towards its symphysis than at the origin of its two
branches, appears under the form of an acute angle whose summit
would be rounded. The mouth is small and surrounded with a
lip, continuous, rounded and uniform on its whole circumference.
Card-like teeth, excessively small, visible only with the magnify-
ing glass, occupy the margin of the jaws. The vomer also has
teeth, but sensibly larger. Upon the pharyngeal bones they become
again as slender as upon the jaws. The eyes are large, almost circular,
one-eighth of an inch in diameter, situated at the upper margin of the
skull, above which they make a regular projection. The distance which
separates them from the end of the rostrum is not quite equal to their
diameter. The nostrils open in two orifices, both nearer to the orbits
than to the end of the rostrum ; the upper orifice is twice as large
as the lower ; this latter is nearest the eye. The cheeks are very

21

306 LAKE SUPERIOR.

prominent and covered with very thin scales, which are hidden in
the skin. Those covering the opercular apparatus are larger and
more conspicuous. The opercular bones are generally smooth ; the
preoperculum is rounded ; the operculum is triangular, with its
summit turned towards the tail, and terminated by two processes,
of which one is a cutaneous, thread-like expansion, the other a direct
continuation of the bone. The suboperculum is of an irregular ellipti-
cal form, extending along the whole lower margin of the operculum.
The interoperculuui is a quite small triangular plate, lost between
the bones above named, which constitute the opercular apparatus.
The branchiostegal rays, as usual, six in number, are slender and
diminish in length on the side of the isthmus between the horns of
the hyoid bone.

The anus is small and a little nearer to the head than to the
tail.

The first dorsal, of a roundish form, is generally separated from the
second ; sometimes, however, a small very low membrane unites the
hinder margin of the one to the anterior margin of the other. It
is composed of nine or ten spinous rays ; the longest occupy the
centre of the fin ; they measure nearly five-sixteenths of an inch ;
the first has only the half of this height ; the two last, which are still
shorter, incline very much on the back. The second dorsal, a little
higher than the first, is equilateral, having its upper margin almost
straight, and its posterior margin half the height of the anterior mar-
gin, where the largest rays are ; they are twelve in number, all bifur-
cated, and a few trifurcated. Its insertion measures about half
an inch. The caudal is inserted on a slightly dilated pedicle
of the tail ; the upper and lower margins, almost straight, diverge
a little on their extent ; the posterior margin is truncated almost in
a straight line ; there are seventeen rays, divided from the first third
part of their length, which is three-eighths of an inch ; on the upper
margin we count six, and on the lower five rudiments of rays ; the
two following on the two margins remain always below the dimensions
of the others, nor do they bifurcate, though they be distinctly
articulated transversely. The anal is opposite the second dorsal,
it is less elevated, equilateral, but its outer margin is rounded ; the
rays, eleven in number, bifurcate beyond their middle ; the ray of

FISHES OF LAKE SUPERIOR. 307

the anterior margin remains very short and simple. The ventrals
are inserted a little behind the pectorals ; they are five-sixteenths
of an inch long ; their form is lanceolate, narrow at the base and
pointed at the extremity ; of the six rays which compose it, that of
the outer margin is simple, the two central ones are the longest and
about equal. The pectorals are the longest of all the fins ; their
posterior extremity exceeds somewhat the ventrals. Their base,
which measures one-tenth of an inch, forms the fourth part of their
length. The rays are twelve ; the central ones are the most elon-
gated ; they diminish regularly to each side, giving thus to the whole
of the fin the form of an oval elongated at both ends.

Br. 6 ; D. IX-12 ; C. 6-17.5 ; A. 11 ; V. I. 5 ; P. 12.

The posterior margin of the scales is semi-circular and finely pec-
tinated. The lateral line is concave, and median on the tail ; it rises
perceptibly as it approaches the head. The back and two-thirds of
the sides are spotted irregularly with black ; excepting a row of
larger spots, extending from the posterior margin of the opercular
apparatus to the pedicle of the caudal. Below this band, and as far
as the under side of the body, it has a uniform yellowish tint. The
dorsal and caudal fins, as well as the base of the pectorals, are
barred transversely with black ; the others have the tint of the belly.

This species was first observed at Fort William ; a large number
of specimens were also collected at the Pic.

PILEOMA, Dekay.

The revision we have made of the species arranged in the genus
Etheostoma by authors, has shown the necessity of subdividing
this group into several smaller genera, for two of which we have
retained names proposed by Dr. Dekay, though he does not seem to
have been aware that his species belonged to Rafinesque's old genus
Etheostoma. Not being able to give at this time a detailed review
of this division without further materials which have no reference to
the fishes of Lake Superior, I shall limit myself to indicating the
general characters of the genus to which I refer the species described
below.

The body is slender, fusiform, compressed. The head is conical,

308 LAKE SUPERIOR.

truncated, terminated by a kind of hog's snout, which perceptibly
exceeds the lower jaw, without, however, sloping over it. The mouth,
very slightly protractile, moderately opened, resembles an oblique arc
of a circle, and opens at the end of the snout. The opercular
apparatus and the cheeks are covered with scales,

Besides the species here described, Etheostoma Caprodes Raf.,
and Pileoma semifasciatum Dekay must rank in this genus.

PlLEOMA ZEBRA, AgaSS.

This species is very near the Etheostoma Caprodes Raf. (Pile-
oma Caprodes Ag.) from which it diifers only in a few peculiari-
ties of the structure of the opercular apparatus, in the direction of
the lateral line, and in the proportional size of the eyes. Pileoma
Caprodes attains larger dimensions than our P. zebra, the largest
specimens which we have had at our disposal, measuring only about
seven inches. Our species is figured Plate 4, figure 4, under the
name of Etheostoma zebra.

The general form of the species under consideration is elegant
and regular. The upper outline of the body describes a slight curve,
rising highest at the middle of the first dorsal; it curves more
abruptly on the head than on the side of the tail, where it becomes
a little concave on the space contained between the hinder margin
of the second dorsal and the insertion of the caudal. The abdo-
men is less convex than the back ; from the insertion of the anal, the
outline rises and becomes slightly convex beyond this fin. The great-
est height perpendicularly above the first dorsal is three-eighths of an
inch. The greatest thickness, which corresponds to the same region,
amounts to about two-thirds of the height. These proportions of the
height and breadth are maintained uniformly along the whole body,
from which a regularly compressed form, from the head to the tail,
results. The head is conical, more pointed than in the other species
of the genus, and forms the fourth part of the length of the body.
The surface of the head is smooth. The eyes are large and subcir-
cular, one-seventh of an inch in diameter, and situated at the upper
margin ; the distance between them exceeds their diameter. The
openings of the nostrils are two on each side, placed one before the

FISHES OF LAKE SUPERIOR. 309

other, at the extremities of a small furrow, arched outwards. The
posterior is the smallest, and occupies the upper and anterior margin
of the eye ; the second is placed nearer to the snout than to the eye
itself.

The scales which cover the opercular apparatus are excessively
thin, and allow the form and outlines of the different bones to be
distinctly seen, the surface of which presents the same silver-colored
reflection as the bare space before the pectorals, which extends also
beneath the head. The ascending branch of the preoperculum is
almost straight at its hinder margin, which is thinned ; the lower
angle is rounded. The operculum has the form of a slightly obtuse
triangle ; the upper angle is armed with a point ; the margin
forming the hypothenuse is slightly concave or undulated. The
suboperculum is proportionally large ; a membranous expansion, in
which the point of the operculum loses itself, terminates its upper
extremity ; its lower extremity extends before the operculum in the
form of a small hook ; the bone itself, like the operculum, is rounded
in the form of a stretched and undulated circle, on its circumference.
The interoperculmn is very small. The cheeks make no projection.
The branchiostegal rays, six in number, are bent and flattened.
The anus is nearer to the tail than to the head. The lateral line is
direct from the centre of the caudal to the head ; beyond the anal
it approaches nearer the back than the belly. The scales are of
middle size ; the clenticulations of their posterior margin are only
visible with the magnifying glass.

Both dorsal fins are distinct and separated from each other. The
first begins at three-fourths of an inch from the end of the snout ; its
insertion is equal to this distance ; its greatest height, which is at the
anterior third, is about one-fourth of an inch, and diminishes gradually
towards its posterior margin. The second dorsal is higher than the
first, and has a basis of less than half an inch ; it is composed of
fifteen bifurcated rays ; its anterior and posterior margins are equi-
lateral ; its upper margin slopes from before backwards, its greatest
height being at the anterior margin. The caudal has seventeen well
developed rays — that is to say — articulated and bifurcated; and
eight or nine undivided rudiments on each of its sides; its pos-
terior margin forms a slight crescent ; its upper and lower margins

310 LAKE SUPERIOR.

are straight. The anterior niargin of the anal is opposite to that of
the second dorsal, but its insertion is an eighth of an inch less, and
it is at least as high, if not higher ; its terminal margin is more
convex ; the greatest rays occupy the anterior third part ; the first
is undivided ; the anterior margin is rounded, the posterior short
and straight ; here are twelve rays. The ventrals have, as usual,
six rays, the first undivided ; their insertion is a little behind the
pectorals ; their length exceeds three-eighths of an inch ; they are
elongated and terminated in a point, which exceeds the posterior
extremity of the pectorals. These latter are somewhat longer than
the ventrals, and are composed of fourteen rays, the longest of which
occupy the centre. The base of these fins measures an eighth of
an inch. When expanded, the rays arrange themselves in the form
of a fan, with a regularly rounded circumference.

The body is barred with black transverse bands, extending from
the back towards the sides. They are alternately longer and shorter.
None are found on the last third of the sides, which has the color of
the abdomen and the lower part of the head. The fins partake of
the color of the region of the body to which they belong. Above,
the head is finely dotted with black.

The few individuals of this species which we have procured were
caught at the Pic.

GASTEROSTEUS NEBULOSUS, Agass.
Plate IV., fig. 4.

The determination of this species has caused us much trouble,
from its great resemblance to G-ast. occidentals Cuv., Cr. concinnus
Richards., and even to Cr. pungitius of Europe, with which the
preceding species are compared in the descriptions of authors.
Another difficulty occurred to us, and rendered the synonymy of Cr.
occidentalis Cuv. very complicated, from Dekay having referred to
this fish an analogous species of the State of New York, which differs
from it ; the same which we find again in Massachusetts, and which
Dr. Storer identifies with Gr. pungitius L. After a minute com-

FISHES OF LAKE SUPERIOR. 311

parison, we have ascertained that the species of Lake Superior,
which we here describe, is a species distinct from all others ;
that Gr. occidentalis Dekay, and Gr. pungitius Storer, are the same
species, differing, however, from the Gr. occidentalis Cuv. This lat-
ter will preserve the name which Cuvier gave to it, and the species
of New York and Massachusetts will be designated under the name
of Gr. Dekayi.

This is not the place to enter into minute details, by means of
which to distinguish the species. We shall soon treat of them in a
monograph of all the species of North America, limiting ourselves
at present to describing the one collected about the Sault of St.
Mary.

The body is subcylindrical or compressed, growing thinner from
the insertion of the dorsal and anal fins towards the tail, which be-
comes very thin and slender, widening at the tip for the insertion of
the caudal. It is from two inches to two inches and one half
long in adult specimens ; its greatest height is at the pectorals, and
is contained six times in the length. The outlines of the back and
belly are slightly convex ; the former from behind the occiput to the
posterior margin of the dorsal fin, where it descends somewhat ; the
latter from the lower end of the snout to the posterior margin of the
anal, being depressed on the tail. The head, from the end of the
snout to the posterior margin of the operculurn, is the fourth part of
the length, and to the occipital carina one-fifth. The head is sub-
conical, generally pointed forwards ; the lower jaw, which somewhat
exceeds the upper in the protraction, forms an angle, reentering
in the retraction. The teeth are minute ; the fissure of the jaws con-
siderable. The eyes, proportionally large, have a diameter of nearly
three-sixteenths of an inch ; the distance which separates their ante-
rior margin from the end of the snout is a little longer than their diam-
eter. The nostrils, which open along this space, are very near the
orbits.

The suborbital bones, only two in number, are far from covering the
cheeks. The first protects the anterior margin of the eyes and the
lower margin of the nostrils, leaving a bare triangular space between
it and the second suborbital, situated below the vertical line which
would pass through the eyeball. It does not exceed the posterior

312 LAKE SUPERIOR.

margin of the orbits, and touches the preoperculum only by its
lower margin. The rest of the cheek, between the eye and the pre-
operculum, remains completely bare. They are finely granulated,
without spines or denticulations, though their outer circumference
presents a few notches. The preoperculum borders the posterior
and lower margins of the cheek in the form of an obtuse angle,
dilated on the summit, and narrow at its margins. The operculum
is triangular with slightly concave sides, the posterior margin round-
ed, and the surface radiately striated. The suboperculum forms an
acute angle ; its anterior branch is convex on the side of the oper-
culum, and concave on the side of the interoperculuin, which has
the form of a small subrectangular triangle.

There are about three equal branchiostegal rays. The branchial
fissure itself is well proportioned. The suprascapular and scapular
bones are not visible externally ; they attach the humeral to the skull.
The upper extremity of the humeral forms a small triangle, with granu-
lar surface, one side of which extends above the base of the pectorals,
thus bounding, at the upper part, the large smooth space which sepa-
rates these latter from the branchial opening. This smooth space is
bordered on its lower circumference by the narrow prolongation of
the cubitus on each side, which, at the lower part of the body, forms
a triangle, whose summit advances like the point of a gothic arch in the
isthmus near to the branchial fissure. The sides extend parallel as
far as the ossa innominata, without uniting with them. They thus
circumscribe a bare triangular space in the enclosure of the arch,
which embraces not quite half of the space, it being a parallelogram
for the rest of its extent. The shield under the belly formed by the
ossa innomiuata is triangular, and the basis turned forwards is stri-
ated transversely at the outer margin, from which is cut a segment
of a circle, which is sometimes obtusely triangular where the bare
space disappears, which the branches of the cubitus circumscribe, as
we have just mentioned. The hinder point of the triangle is obtuse,
and terminates at some distance from the anus. The ventral spine
does not quite reach the extremity of the triangle. The ascending
branch of the ossa innominata rises at a small distance from the pec-
torals, inclining backwards. It is somewhat more dilated at its sum-
mit than at its origin, forming thus an elongated isosceles triangle,

FISHES OP LAKE SUPERIOR. 313

striated at its surface. The anus is situated a little behind the
middle of the length.

There are generally nine spines on the back ; a single instance of
eight has occurred from among a hundred individuals submitted to our
examination ; none contained ten. A small triangular and very low
membrane extends from the inferior third and inner part of each of
them, to rejoin the back. These spines, of an average height of a tenth
of an inch, are thin and bent somewhat backwards ; the last, which is
bent a little more than the others, is always independent of the soft
dorsal. This latter is generally composed of ten, sometimes eleven,
soft rays, upon a base of about two-fifths of an inch ; all are bifurca-
ted, as is the case with the other fins for three-fifths of their length ;
at the anterior margin the rays are almost one-fifth of an inch in
height, whilst on the posterior margin they are confounded with the
line of the back, which gives to this fin the form of a triangle. The
anal, which is exactly opposite to it, has somewhat the same form, with
a somewhat shorter base, which recedes a little at its anterior margin ;
it contains nine rays, and in a few exceptional cases eight ; it is some-
what lower than the dorsal. The caudal is rounded, rather concave
on its posterior margin ; there are constantly twelve bifurcated
rays, (six in each lobe,) and four rudimentary ones at the upper
margin, and as many at the lower ; the inner one has twice the
length of the three others ; the largest rays are about one-fifth of
an inch in length. The bare space of the upper and lower margins
of the tail, which separates the caudal from the termination of the
dorsal and anal, varies between one-third and two-fifths of an inch.
The pectorals are sometimes as much as three-tenths of an inch long ;
they are composed of ten nearly equal rays ; their form is oval,
narrowed towards the base. The ventrals are, as in most species,
reduced to a spinous ray, inserted on the ossa irmominata, with a
small membrane from the axilla, at the centre of which a small sim-
ple ray is observed. The spinous ray is here very elongated, since
it nearly reaches the posterior extremity of the ventral cuirass,
against which it leans when at rest. It is about one-sixth of an inch
long, slightly curved within, excavated at the inner side of its base,
sulcated on its outer surface, thin like those of the back, and with the

magnifying glass, traces of fine denticulations may be discerned at
its inner margin.

D. IX-10 ; A. 9 ; C. 4. 12.4 ; P. 10 ; V. I. 1.

The body, besides the bones of the belly, is completely bare and
unprovided with scales. On the sides of the tail we remark a small
carina, which extends from the hinder third of the dorsal and
anal fins to the basis of the caudal. This carina is formed by
small bony pieces, upon which rise small depressed hook-like points.
The lateral line is continued from the anterior extremity of this
carina to the occiput, following the back-bone.

This species has been found in abundance at the Pic. When alive,
its color is of an olive brown above, mottled with blackish brown and
silvery white below.

GASTEROSTEUS PYGIVLEUS, Agass.
Plate IV., fig. 1.

This species is very inferior to the 6r. concinnus in its size, so that
we have in it, and not in this latter, the true pigmy of the genus.
Its length does not attain eleven-sixteenths of an inch. The head,
measured from its anterior extremity to the posterior margin of the
operculum, has a little more than one-fourth of it. Its height varies
between one-seventh and one-eighth of an inch, and remains nearly
the same from the nape of the neck to the anterior fourth of the dorsal.
The eyes are proportionally large ; the nostrils, situated at the upper
margin of the orbits, occupy the middle of the space between this
latter and the end of the snout. The head is somewhat sloping.
The curve of the back, very elliptical on its middle, descends abruptly
towards the tail about the insertion of the soft dorsal ; that of the
belly is slightly convex, and ascends also very abruptly, to form, in
conjunction with that of the back, a narrow contraction on the middle
of the peduncle of the tail, which is remarkably short, measuring
scarcely one-eighth of an inch from the posterior margin of the
dorsal and anal fins to the origin of the caudal. The anus is placed
seven-sixteenths of an inch from the head. The body is completely
bare ; the bones of the head are smooth ; the opercular apparatus

FISHES OF LAKE SUPERIOR. 315

hidden under the skin ; the whole dotted with black. The space
between the pectoral fins and the branchial opening is sensibly
reduced, and covered by the skin, the aspect of which is the same
as on the rest of the body. The thoracic arch is not visible ; we
have also scarcely found traces of the cuirass formed by the ascend-
ing branch of the innominated bones, and about the basis of the
ventral spines, which are perceived only with the magnifying glass,
under the form of very small hooks.

It was difficult to count the exact number of the rays of the fins,
as they are very thin and slender. We have, however, recognized the
existence of at least six dorsal spines ; the last of which is well devel-
oped, and has a small membrane at its posterior margin, arising
from the summit of the spine to unite the basis of the soft dorsal.
This latter seems to have seven rays, composing a triangular fin, whose
posterior angle rests on the tail. The anal has the same form,
but is somewhat smaller, opposite to the dorsal, and provided with
six rays. The caudal is short, rounded, and has twelve rays, perhaps
even fourteen, for the two exterior ones appeared to us almost twice
as thick as the others. The pectorals are pointed, and have eight
rays of an extreme thinness. As for the ventrals, as we have seen
above, they are only visible with the magnifying glass, and all we
have been enabled to do was to satisfy ourselves of the presence of
the spinous ray common to all species.

Three individuals of this species were found at Michipicotin. Two
from among them are only one-quarter of an inch long.

ESOCID,E, (The Pickerels.'}

The family of pickerels is perhaps the least understood of any in
the whole class. From the characters assigned to it bv Cuvier. it

C3 *•

contains a variety of fishes, which can scarcely belong to one and the
same natural group, and indeed more recent investigators, as, for
instance, Joh. Miiller, have divided the Esoces of Cuvier into two
families, on the ground of the pseudo-branchiae ; so that we have
now the families of Scomberesoces in addition to the true Esoces.
Several isolated genera formerly referred also to the family of the
Esoces, have either been removed to other natural groups, or become

316 LAKE SUPEKIOR.

the types of distinct families for themselves, as Lepidosteus and
Poljpterus.

No species of Scomberesox are found in Lake Superior, nor in
any of the lower lakes, although they occur in the Atlantic rivers of
these latitudes, where Belone truncata is not uncommon, and with it
Scomberesox Storeri. Without discussing for the present the natu-
ral relations of the Esoces and Scomberesoces, I cannot but think
that the Scomberesoces are an aberrant type of the great family of
Scombridre, with abdominal vcntrals and some other peculiarites.

The true Esoces, as circumscribed by Joh. Miiller, are very few ;
indeed his family contains little else than the true genus Esox, fishes
which are all inhabitants of the fresh waters, and occur chiefly in the
temperate zone ; their structural peculiarities are such that it is diffi-
cult to understand their true affinities ; their cylindrical, elongated
form indicates a low position among abdorninales, as does also the
composition of their mouth, the maxillary being entirely deprived of
teeth, while the palatal bones contain a powerful armature ; the
connection of the intermaxillaries and maxillaries in one arch places
them however in the vicinity of the Salmonidee. The skeleton, and
especially the skull, is remarkably soft in these fishes.

North America seems to be the proper fatherland of the genus
Esox, its species being numerous all over this continent, from the
great northern lakes, through all the rivers and lakes of the east and
west, and as far south even as Florida. In North America, there-
fore, a deeper study of this family becomes alone possible, in relation
both to the knowledge of species and their affinities with the other
families of the class.

The species are certainly more numerous than the American au-
thors who have written on the pickerels have recognized ; and if we
had for examination specimens from all localities of this continent, we
might now publish the result of our observations on this family. But,
unwilling to introduce in our science unconnected observations, espe-
cially on a difficult and controverted subject, we prefer to recur at a
future time to this family. We shall limit ourselves here to a de-
scription of the species collected from Lake Superior. But its bare
description would be without interest, did we not compare it with the
species already described from the region of the lakes. Two species

FISHES OF LAKE SUPERIOR. 317

are mentioned by Dr. Richardson : an Esox Lucius and an Esox
Estor Lesu. Now the species of Lake Superior is not the Lucius
of the Fauna Boreali-Americana, as we might infer by comparing the
descriptions. In regard to this, we could entertain no doubt. As
for the Esox Estor of Dr. Richardson, we allow that we have doubts
whether or not the author of the Fauna Boreali-Americana had the
true Esox Estor Lesu., or perhaps my Esox Boreus, from^Lake Su-
perior. The description which he gives of it* is too incomplete to
enable us to recognize it ; the more so, as that description is made
with reference to Esox Lucius, which is found to be quite different.
Only two characters occur which may be considered to have some
value ; but, strange to say, these two characters are found united in
none of the species which I know. I mean, first, the form of the
scales, which are as high as they are long, a character which we
find in the true Esox Estor Lesu. But, again, the scales would be
much smaller in the species which Dr. Richardson had in view.
The Esox Estor Lesu. is the species which has the least number of
scales on the cheeks and opercula ; but Dr. Richardson gives for his
E, Estor two rows of scales, which descend along the anterior mar-
gin of the operculum until they attain the upper angular process of
the suboperculuin. It is therefore possible that the species referred
to Esox Estor by Dr. Richardson was neither the Esox Estor Le-
sueur, nor my Esox Boreus, but a species distinct from all others,
as the small size of its scales seems to indicate.

Esox BOREUS, Agass.

When marked external zoological characters are wanting in a
group, on account of its uniformity, it becomes necessary to resort
to another series of facts. When the object is to find the place
which a certain family occupies in its order or in its class, compara-

completely as an anatomical investigation, and even with more pre-
cision. If, on the contrary, we have to do with the distinction of
species, we may in such cases have recourse to comparative anat-

omy. In the present instance, we have had no occasion to hesitate.
Having seen by turns the general form, the outlines of the fins, the
outer details of the head, and the color, sometimes varying in the
same species to a great extent, and at others preserving a monot-
onous uniformity, we have taken for our guide the structure of the
mouth, and particularly that of the palatal bones and of the vomer,
and we may say, that whenever we have had series of specimens at
our disposal, the general traits of the species have not varied sensi-
bly. We have relied still more confidently on this method, when,
after comparing the buccal apparatus, we have seen the extreme
variations stop in these limits.

What strikes us, especially in the species here referred to, is the
general smallness of the rows of palatal and vomeric teeth. None
make a strong projection above the others. The surface of the
palatals has a very uniform appearance, and it is only when we ex-
amine them closely, that we perceive that the teeth of the inner row
alone exceed those of the body of the bone in size by about one-third,
though remaining equal among themselves. The palatal bones
themselves are slightly bent, with the convexity turned inwards.
Their greatest length is one and a half inches, their greatest breadth
one-third of an inch, which maintains itself on the anterior two-
thirds, diminishing sensibly on the posterior third, the extremity of
which terminates in an oblique line, extending from the front back-
wards. The anterior margin is oblique from behind forwards, as in
most species, owing to the curve of the snout. The vomer, includ-
ing its dilatation and the narrow band, is one and nine-sixteenths
inches long. The dilatation is of a triangular form, rounded at the
anterior margin, and slightly concave on its sides ; its centre is
depressed, concave. A certain number of teeth, larger than those
of the centre, occupy its circumference. The narrow band of teeth
upon the vomer is lanceolate, and terminates in an acute point a little
beyond the extremity of the palatals. We barely observe a con-
traction at the place where it enlarges at its anterior part. In the
centre it is one-eighth of an inch broad. The teeth which cover
its surface are very small. The intermaxillaries do not measure
five-eighths of an inch ; they have a single row of teeth as small as
those of the vomeric band. The same is the case with the teeth of the

FISHES OF LAKE SUPERIOR. 319

lower jaw as with those of the palate. The largest, situated on the
posterior two-thirds of the maxillary branches, are uniform among
themselves and regularly spaced, slender, flattened, and their acute
point is curved either backwards or inwards. At the anterior part,
and on the sytnphysis, the same uniformity exists ; and though form-
ing only one single row, they are grouped in pairs. They incline
towards the interior of the mouth, and are more conspicuous than on
the body of the palatal bones.

The tongue is slightly dilated, laterally rounded, subtruncated at
its anterior margin. It has on its middle two contiguous shields,
covered with excessively small, card-like teeth. The posterior, of
elliptical form, is six-eighths of an inch long, and one-fourth of an
inch broad. The anterior, half as long, terminates in a conical point,
at a distance of one-third of an inch from the end of the tongue.
We remark two small, similar shields on the symphysis of the branch-
ial arches. The pharyngeal bones are furnished with card-like teeth
of great uniformity.

The external characters of this species may be indicated in the
following manner. In general it is fusiform, the greatest thickness
corresponding to the middle of the length, whence the body seems to
taper towards both its extremities. The head forms one-fourth of the
whole length ; its conical form is merely the result of the attenuation
of the body forwards, which renders it proportionally small ; its
upper face is flattened ; a medium furrow, with widened margins,
occupies the centre of it, between both eyes. The snout is depressed,
and terminates in an elliptical curve, which exceeds the extremity of
the lower jaw. Numerous and considerably large pores extend on
the frontals above the snout ; from the occiput they pass beneath
the orbits and through the preoperculum on the branch of the lower
maxillary. The mouth is moderately opened. The eyes are large and
elliptical ; their horizontal diameter is eleven-sixteenths of an inch,
their vertical diameter nearly five-eighths of an inch. The nasal ori-
fices, two in number on each side, open before and within the eyes ;
the hinder is separated from the orbit by a space of only one-fourth
of an inch ; it is crescentic, with the convexity turned towards the
eye ; a membranous fold shuts its opening ; the anterior is ovoid, and
has a large opening outwards. The cheeks are completely covered

320 LAKE SUPERIOR.

with scales as also the upper half of the operculum. The rest of
the opercular apparatus is bare. The preoperculum is narrow, its
posterior margin undulated. The operculum is trapezoidal ; its an-
terior margin concave ; the posterior rounded, and the lower oblique.
The suboperculuni, somewhat longer than the operculum, is about
one-third as broad, being, however, somewhat more narrow behind
than in front. The interoperculum is very narrow and elongated,
being undulated like the preoperculum on its outer margin. The
brauchiostegal membrane is narrow ; it contains fifteen rays, of which
the first is much the broadest ; all are flattened or compressed ; the
longest are two inches ; the shortest five-eighths of an inch long.

The body grows thinner towards the tail from the ventrals, under-
going a considerable contraction behind the dorsal and anal fins. It
widens again at the insertion of the caudal.

The dorsal fin has a quadrangular form, its upper margin being
only slightly arched ; it is two and three-eighths inches long and two
inches high. The rays are twenty-one in number ; the three first are
very short, and are applied towards the fourth ; the three last diminish
equally in height ; its posterior margin is at a distance of three inches
from the rudimentary rays of the caudal. The anal is situated a
little farther back than the dorsal, at a distance of two and three-
eighths inches only from the basis of the caudal ; its circumference is
rounded ; there are ten rays ; the four first near the fifth ; its length
is an inch and six-eighths, its height two inches, making it, of course,
higher than long. The caudal is composed of eighteen rays ; it is
notched ; the breadth at the extremity of the two lobes measures
three and a half inches ; the largest rays correspond to the middle of
each lobe ; they are two and six-eighths inches long, whilst in the
centre they are scarcely one inch and a half ; very small interradial
scales extend over a space of three-fourths of an inch for each lobe
from their insertion. The ventrals contain eleven rays ; they are
somewhat nearer the anal than the pectorals are, and also nearer to
the head than to the extremity of the caudal, being situated at ten
and six-eighths inches from the snout ; the whole length being nearly
one foot eight inches ; their form is broad and rounded on the outer
circumference ; their insertion measures about five-eighths of an inch,
their greatest breadth one inch and a fifth, and their length two

FISHES OF LAKE SUPERIOR. 321

inches. The pectorals, composed of sixteen rays, have the same
general form as the ventrals, but still more rounded, longer, and
broader by one-fourth of an inch, with a basis of insertion of eleven-
sixteenths of an inch.

The scales are oblong, longer than broad, and proportionally larger
than in the Esox Estor Lesu. We may count four of them on the
space of three-eighths of an inch. The lateral line is very distinct ;
it follows the middle of the body from the basis of the caudal to a
point in front of the dorsal and anal fins, whence it rises to terminate
at the height of the upper third of the operculum.

The upper side of the head, the back, and the upper half of the
sides are bluish black, amidst which the scales shine with a metallic
azure reflection. The face and the lower half of the sides have a
lighter tint, are sprinkled with whitish spots, arranged in horizontal
or oblique bands on the face, spherical or ovoid on the sides, and dis-
posed in ill-defined longitudinal rows. The lower side of the head
is white ; the abdomen is very pale yellow. The fins have an olive-
colored tint ; the caudal has black spots, elongated in the direction
of the rays ; these spots affect less regularity on the dorsal and anal,
and disappear almost entirely on the ventrals and pectorals.

In the young individual, the spots of the sides do not exist, as such.
The general color is more olive, more uniform, and the body is barred
vertically with sinuous white bands, which are now and then inter-
cepted. This fish was obtained from various places along the north-
ern shores of Lake Superior.

GADOIDS.

The family of codfishes contains numerous species, closely allied,
all of which are circumscribed within the colder regions of both
hemispheres. The northern seas especially teem with codfishes of
various kinds, and the number of individuals of some of the species
must be countless, if we judge by the quantity caught annually.
Taken as a whole, this family consists of low forms, their body being
very much elongated, their vertical fins very large, and the ventrals
placed in such a position under the chin, as shows that when they
22

322 LAKE SUPERIOR.

were formed, the vertical fin extended underneath very far forwards.
The abdominal cavity extends also far backwards. In some of the
genera, the dorsal, caudal, and anal remain continuous ; in others,
they are slightly divided ; in others, they become subdivided into
many fins, but in all they extend very far forwards. From their geo-
graphical distribution in the colder portions of the northern hemi-
sphere, we need not be surprised at finding a good many of these
fishes among the freshwaters, as the northern seas contain less salt
than the other portions of the ocean.

The real affinities of the family are still obscure to me. From
their peculiar affinities, they stand very much by themselves ; how-
ever, the large size of the head, the developments of the dorsals, and
even the structure of the skeleton, seem to bring them near the Lo-
phioids ; and, on the other hand, I cannot but think the Scomberoids
somewhat related to them, especially when comparing the Merluccius
with Naucrates, etc. In Lake Superior, one single species of that
family occurred.

The first account we possess of the Gadoids of North Amer-
ica dates back to the year 1773. At that epoch, J. Reinhold
Forster published descriptions of four species of fishes of Hudson's
Bay, in a letter addressed to Pennant,* among which a Lota is
mentioned, which he identifies with the European species, so well de-
scribed, he says, by Pennantf himself, that he thought it superfluous
to add anything. The sole difference that struck him, was a larger
size, and six branchiostegal rays instead of seven. Pennant after-
wards inscribes it, in his Zoologia Arctica, under the same denomina-
tion of G-adus Lota L.

In 1817 Lesueur published descriptions of two species which he
considered as new, under the names of G-adus maculosus and G-adus
compressm,\ but he cites neither Forster nor Pennant, thinking,
no doubt, that they had seen the European species. The same
year Dr. Mitchill, though acquainted with the writings of Lesueur,
seems not to have been aware that the latter had just named his
species, and proposed to call the first G-adus lacustris.^ Here

already begins a discrepancy in the characters assigned to this spe-
cies. Lesueur says, "jaws equal" and Mitchill, " upper jaw long-
est, and receiving the lower." He adds : " The skin is smooth and
scaleless" The smallness of the scales must have misled him ; if
not, his G-adus lacustris is not the Cf-adus macidosus- of Lesueur.
Dr. Richardson mentions the Cf-adus Lota in his Journal of the Expedi-
tion of Franklin, published in 1823 ; and in 1836, when publishing
the Fauna Boreali-Americana, he describes, under the name of Lota
maculosa, a species from Pine-Island-Lake, which must be the same
he had seen in 1823, since he gives the same synonyms. The
description is considerably detailed, but it contains no criterion
establishing the perfect identity with the species of Lesueur. He
agrees on the point that the jaws are of equal length, but as
for the lateral line, Lesueur had said, "in the middle of the body"
and Richardson says', " nearer to the back than to the belly, and is
slightly arched till it passes the first third of the anal fin, after
which it takes a straight course" etc.

In 1839 Dr. Storer* gave a short description of the Cf-adus com-
pressus Lesu., which he places, however, in the genus Lota, without
trying to establish a connection between his description and that of
Lesueur.

In 1842 Dr. J. P. Kirtlandf copies the description of Cr. maculosus
of Lesueur, and cites Richardson in the synonyms. He adds a fig-
ure. In the same year, 1842, Rev. Z. Thompson J describes a species
from Lake Champlain, comparing it with the description of Cr. macu-
losus Lesu., and though retaining for it this name, he remarks certain
differences which strike him. Thus, the upper jaw is uniformly longer,
and the lateral line, " anterior to the vent, is much nearer the back
than the belli/." In this sense, the lateral line agrees with the
description of Dr. Richardson. Mr. Thompson finds much resem-
blance between his fish and that described by Dr. Storer under the
name of Lota Brosmiana, but it differs from it, he says, " in having
the upper jaw longest, in having the snout more pointed and less
orbicular." He finds that his fish differs as much from the Lota

maculosa Lesu. and Lota Brosrniana Storer, as these latter differ
among themselves ; and that they constitute three species or only one.
Here, for the first time, we have a critical and comparative examina-
tion, but it does not satisfy the writers who follow him, or they
seem, indeed, not to have known his account.

As to Lota compressa Lesu., Mr. Thompson was not acquainted
with it, and, in his turn, he copies the description of Dr. Storer.

The Natural History of the Fishes of New York appeared also in
1842. Lota maculosa is there inserted with a long list of synonyms,
but without comparative criticism. Then characters are noticed, to
which nobody had made allusion before. Such are : " Pectorals long,
pointed ; their tips reaching nearly to the base of the first dorsal " —
"first dorsal small, subtriangular ; " and a figure to confirm them.
Dr. Dekay says, however, he is acquainted with Lota compressa only
through the descriptions of Lesueur and Storer, from whom he may
have borrowed his. But whence comes his figure, which exists
nowhere else, so far as I know ? Dr. Dekay describes and figures also
another species, which he considers as new, under the name of Lota
inornata from the Hudson River, and which Dr. Storer considers as
synonymous with his Lota Brosmiana, of New Hampshire.* Cer-
tainly, if this identity is real, it does not exist in the figures which
these two authors have published, nor even in their descriptions, since
the one, (Lota inornata Dekay,) has the upper jaw larger than
the lower, while in the other (Lota Brosmiana Storer) both jaws
are equal. And there are still other differences.

In such a state of things, it was impossible for me to establish the syn-
onymy and to compare critically the species without original specimens
for comparison. Possessing myself only such specimens as I procured
at Lake Superior, I will describe, provisionally, that species under the
name of Lota maculosa, without synonymy, and I will limit myself
to indicating the analogies and the differences which I have observed,
I will not say in the published figures, but in the original descriptions
of the authors. The question, thus restored to its true position, may
in future lead to further progress.

FISHES OF LAKE SUPERIOR. 325

LOTA MACULOSA.

The description which best coincides with our specimens is that of
Mr. Thompson of the Lota of Lake Champlain, and which we have
cited above. The wood-cut which he gives of it, though much
reduced, sustains this assertion. I will remark one difference only,
which is, that the snout is more pointed, and the upper lip slopes more
over the lower jaw than in the specimens from Lake Superior. The
first dorsal fin seems also to be higher than the second.

Dr. Richardson not having figured the species which he describes,
we have compared attentively his description with our specimens,
to which it applies in a general way, as also in several peculiarities ;
nevertheless, we would direct the attention of ichthyologists to the
following differences : The head is proportionally more elongated,
forming only the fifth part of the whole length ; the snout more pointed,
the upper jaw somewhat longer than the lower ; this latter is besides
considerably exceeded by the upper lip. The distance which separates
the centre of the orbit from the end of the snout is equivalent to three
lengths of the axis of the orbit itself ; this axis is contained four times
and a half on the space which extends from this same point of departure
to the posterior margin of the operculum, being contained seven times
and a half in the whole length of the head. The eyes themselves are
besides situated at the upper margin of the face, so as to be seen from
above. The labials are an inch and a half long, the intermaxillaries
one inch. These measures, compared with those which Dr. Richardson
gives, show us remarkable differences in the proportions of these
bones. The posterior extremity of the labials is besides curved
forwards.

Among the fins I find the second dorsal, if not higher than the first,
at least as high. The anal is generally lower, though having the
same form, and like the second dorsal, rounded and somewhat higher
at its termination. The anal terminates a little before the dorsal.
The ventrals have seven rays ; the second is the longest. Formula :

Br. 7 ; D. 11-76 ; A. 64 ; C. 45 ; V. 7 ; P. 19.

The skin which envelopes the fins is thick, a character which
we find again in Lota compressa, which seems, however, to be a much
smaller species.

326 LAKE SUPERIOR.

The head is much depressed. The body is subcylindrical from the
occiput to the anus. The tail is also much compressed, and its
height diminishes quite insensibly from before backwards.

The color is dark olive brown above, mottled with blackish brown ;
sowewhat yellow about the lower part of the abdomen, and whitish
underneath.

It is very difficult to decide what are the characters which dis-
tinguish Lota compressa from Lota maculosa. It seems that the spe-
cies is generally smaller. Lesueur gives to it an upper jaw longer
than the lower, a character alternately given to it and L. maculosa
by the authors who have written after him. Whether the body is pro-
portionally shorter is to be verified anew, as also the greater com-
pression of the sides, and the back, which is said to be highest at
the basis of the dorsal fins. Lesueur adds, as a character, a more
elongated caudal, an equal dorsal and anal.

The description of Dr. Storer, the only one which has been made
from nature since Lesueur, as it is not comparative, does not soive
the question.

So long as the family of Salmonidne remains circumscribed as it
•was established by Cuvier, it seems to be a type almost universally
diffused over the globe, occurring equally in the sea and in freshwater,
so that we are left almost without a clue to its natural relations to the
surrounding world. Joh. Miiller, working out some suggestions of
prince Canino, and introducing among them more precise anatomical
characters, had no sooner subdivided the old family of Salmonidae
into his Salmonidre, Characini and Scopelini, than light immediately
spread over this field. Limited now to such fishes as, in addition to
the mere general character of former Salmonidoe, have a false gill on
the inner surface of the operculum, the Salmonidse appeared at
once as fishes peculiar to the northern temperate region, occurring
in immense numbers all around the Arctic Sea, and running regu-
larly up the rivers at certain seasons of the year to deposit their
spawn, while some live permanently in freshwater. We have thus
in the true Salmonidse actually a northern family of fishes, which,

FISHES OF LAKE SUPERIOR. 327

when found in more temperate regions, occurs there in clear mountain
rivers, sometimes very high above the level of the sea, near the limits
of perpetual snow, or in deep, cold lakes. That this family is adapt-
ed to the cold regions is most remarkably exemplified by the fact
that they all spawn late in the season, at the approach of autumn
or winter, when frost or snow has reduced the temperature of the
water in which they live nearly to its lowest natural point. The
embryos grow within the egg very slowly for about two months
before they are hatched ; while fecundated eggs of some other fami-
lies which spawn in spring and summer, give birth to young fishes a
few days after they are laid. The Salmonidge, on the contrary, are
born at an epoch when the waters are generally frozen up ; that is,
at a period when the maximum of temperature is at the bottom of the
water, where the eggs and young salmons remain among gravel,
surrounded by a medium which scarcely ever rises above thirty
or forty degrees.

It is plain from these statements, and from what we know other-
wise of the habits of this family, that there is no one upon the globe
living under more uniform circumstances, and nevertheless the species
are exfternely diversified, and we find peculiar ones in all parts of
the world, where the family occurs at all. Thus we find, in Lake
Superior, species which do not exist in the course of the Mackenzie
or Saskatchawan, and vice versa, others in the Columbia river which
differ from those of the Lena, Obi, and Yenisei, while Europe again
has its peculiar forms.

Whoever takes a philosophical view of the subject of Natural
History, and is familiar with the above stated facts, will now under-
stand why, notwithstanding the specific distinctions there are between
them, the trouts and whitefishes are so uniform all over* the globe.
It must be acknowledged that it is owing to the uniformity of the phys-
ical conditions in which they occur, and to which they are so admira-
bly adapted by their anatomical structure, as well as by their instinct.
Running up and down the rapid rivers and mountain currents, leaping
even over considerable waterfalls, they are provided with most pow-
erful and active muscles, their tail is strong and fleshy, and its broad
basis indicates that its power is concentrated ; it is like the paddle of
the Indian who propels his canoe over the same waters. Their

mouth is large, their jaw strong, their teeth powerful, to enable them
to secure with ease the scanty prey with which they meet in these
deserts of cold water, and nevertheless, though we cannot but be
struck by the admirable reciprocal adaptation between the structure
of the northern animals and the physical condition in which they
live, let us not mistake these adaptations for a consequence of physical
causes, let us not say that trouts resemble each other so much
because they originated under uniform conditions ; let us not say
they have uniform habits because there is no scope for diversity ;
let us not say they spawn during winter, and rear their young under
snow and ice, because at that epoch they are safer from the attacks
of birds of prey ; let us not say they are so intimately connected
with the physical world, because physical powers called them into
existence ; but let us at once look deeper ; let us recognize that this
uniformity is imparted to a wonderfully complicated structure ; they
are trouts with all their admirable structure, their peculiar back
bones, their ornamented skull, their powerful jaws, their movable
eyes, with their thick, fatty skin and elegant scales, their ramified
fin-rays, and with all that harmonious complication of structure which
characterizes the type of trouts, but over which a uniform rooe, as it
were, is spread in a manner not unlike an almost endless series of
monotonous variations upon one brilliant air, through the uniformity
of which we still detect the same melody, however disguised, under
the many undulations and changes of which it is capable.

The instincts of trouts are not more controlled by climate than
those of other animals under different circumstances. They are only
made to perform at a particular season, best suited to their organiza-
tion, what others do at other times. If it were not so, I do not see
why all the different fishes, living all the year round in the same
brook, should not spawn at the same season, and finally be transformed
into one type ; have we not, on the contrary, in this diversity under
identical circumstances, a demonstrative evidence that there is an-
other cause which has acted, and is still acting, in the production and
preservation of these adaptations ; a cause which endowed living
beings with the power of resisting the equalizing influence of uniform
agents, though at the same time placing these agents and living beings
under definite relations to each other ?

FISHES OF LAKE SUPERIOR. 329

That trouts are not more influenced by physical conditions than
other animals, is apparent from the fact that there are lakes of small
extent and of most uniform features, in which two or three species
of trout occur together, each with peculiar habits ; one more migra-
tory, running up rivers during the spawning season, etc., while the
other will never enter running waters, and will spawn in quiet places
near the shore ; one will hunt after its prey, while the other will wait
for it in ambuscade ; one will feed upon fish, the other upon insects.
Here we have an example of species with different habits, where
there would scarcely seem to be room for diversity in the physical
condition in which they live ; again there are others living together
in immense sheets of water, where there would seem to be ample
scope for diversity, among which we observe no great differences, as
is the case between the Siscowet and the lake trout in the great
northern lakes.

If these facts, statements and inductions were not sufficient to
satisfy the reader of the correctness of my views, I would at once
refer to another material fact, furnished us by the family of Salmon-
idae, namely, the existence of two essential modifications of the true
type of trouts, occurring everywhere together under the same cir-
cumstances, showing the same general characters, backbone, skull,
brain, composition of the mouth, intestines, gills, &c., &c.,but differ-
ing in the size of the mouth, and in the almost absolute want of
teeth, these groups being that of the whitefishes, Coregoni, and that
of the true trouts, Salmones.

Now I ask, where is there, within the natural geographical limits of
distribution of Salmonidae, a discriminating power between the physi-
cal elements under which they live, which could have introduced those
differences ? A discriminating power which, allotting to all, certain
characters, should have modified others to such an extent as to pro-
duce apparently different types under the same modification of the
general plan of structure. Why should there be, at the same time,
under the same circumstances, under the same geographical distrib-
tion, whitefishes with the habits of trout, — spawning like them in the
fall, growing their young like them during winter, — if there were not
an infinitely wise, supreme Power, if there were not a personal God,
who, having first designed, created the universe, and modelled our

330 LAKE SUPERIOR.

solar system, called successively, at different epochs, such animals into
existence under the different circumstances prevailing over various
parts of the globe, as would suit best this general plan, according to
which man was at last to be placed at the head of creation ? Let us
remember all this, and we have a voice uttering louder and louder
the cry which the external world equally proclaims, that there is a
Creator, an intelligent and wise Creator, an omnipotent Creator of all
that exists, has existed, and shall exist.

To come back to the Salmonidte, I might say, that when properly
studied, there is not a species in nature, there is not a system of
organs in any given species, there is not a peculiarity in the details
of each of these systems, which does not lead to the same general
results, and which is not, on that account, equally worth our con-
sideration.

A minute distinction between species is again, above all, the
foundation of our most extensive views of the whole, and of our
most sublime generalizations. The species of Salmonidse call partic-
ularly our attention from the minuteness of the characters upon
•which their distinction rests. Their number in the north of this
continent is far greater than would be supposed, from the mere
investigation of those of the great lakes ; but I shall, for the present,
limit myself to these.

Though this species has been known for a long time and has

FISHES OF LAKE SUPERIOR. 331

often been cited, no satisfactory figure o£ it has yet been published.
Having, to my great disappointment, been unable to supply this
deficiency, I will not undertake to give a detailed description of it.
Those of my readers who desire to know it, will have to consult
the works • cited in the synonomy, supplying from one what is not
furnished by another. In order to complete the history of this fish
with success, it will be necessary to give a figure of it with all the
exactness of modern science.

The color varies as much as in the Salmo Fario of Europe. To
one of the varieties Rafinesque gave the name of S, nic/rescens.
The physiognomy of the young is somewhat different from that of the
adult, which has induced Dr. Dekay to make a separate genus of it,
which he calls Baione. At that epoch the body is barred vertically
with black. There are seven, eight, nine and even ten bands, which
grow wider and assume the form of circular spots the more the fish
grows. The teeth are all minute and uniform, in these young speci-
mens, and have misled Dr. Dekay to view these fishes as the type
of a distinct genus. We have procured several individuals of two
and three inches, at Black River, with others of from twelve to
fifteen inches.

This species is well known under the trivial name of " Tyrant of
the lakes," because of its size and voracity, and is much esteemed
for food in the countries which it inhabits. As it has been well known
for a very long time, I will not repeat what has been said by my pre-
decessors, but shall limit myself to citing a few observations which I
have been able to make on the living animal. The general color

332 LAKE SUPERIOR.

varies with the ground on *rhich it is caught. Those found on a
muddy bottom are generally grayish, while those from a gravelly bot-
tom are of a reddish color, with much brighter fins. The amethystine
color does not show itself distinctly while the fish is swimming, or
when first caught, but only after being taken from the water, when
the mucus on the surface begins to dry. The sexes differ in shape,
the male having a more pointed head than the female, although the
jaws are of equal length. The dentition, though somewhat stronger
than in the S. Siscowet, presents generally the same disposition. The
vomer especially has the same structure ; there is a row of teeth on
the hinder and rounded margin of the chevron, with a middle row on
the body of the bone itself. According to Dr. Richardson, there
should be here a double row of teeth. Probably in growing, they are
thrown out alternately and obliquely, and thus cause the row to
appear double. I should not know how to explain otherwise this
divergence, unless the disposition of the teeth upon this bone be sub-
ject to great variations, which seems not to be probable. The
description of Dr. Dekay is very obscure in relation to the teeth of
this species. He speaks of a double row of teeth on the vomer and
the palatines, which is an error, especially with regard to the latter.
When he says that they are in two series along the labials, of which
the outer is smaller and more numerous, he evidently speaks of the
palatines and upper maxillary together ; therefore, if the upper max-
illary and the palatines constitute in his view a single group (labials)
of two rows, the palatines cannot at the same time have a double
row. This description may have been copied without being under-
stood, like the figure itself, which is taken from the Fauna Boreali-
Americana.

The small ossicles of the branchial arches are nearly straight and
denticulate on their outer margins, as in the Salmo Siscowet. The
bony shields of the pharyngeals are considerably developed, and the
teeth which cover them arranged like cards, and very prominent.
There is one behind the tongue, narrow and elongated ; another, but
somewhat smaller, which corresponds to it, on the vault of the
palate, and behind these two, and surrounding the large throat, two
upper and two lower pharyngeal shields.

This species was mentioned by Pennant, towards the close of

FISHES OF LAKE SUPERIOR. 333

the past century, under the name of S. namaycush, which must be
preserved in spite of the more euphonious name which Dr. Mitchill
gave to it twenty-five years later, even if the character to which this
latter makes allusion were constant during the whole life of the
fish.

Our specimens have been collected all along the northern shores.

SALMO SISCOWET, Agass.
PI. I., fig. 3.

Along with the two species of salmons above mentioned, Lake
Superior furnishes a third, which has not yet been described.
The inhabitants of the region designate it under the name of Sis-
cowet, a name which I have thought should be preserved in scientific
nomenclature. Its general form is stout, broad and thick, more so
than any species of salmon except the S. Trutta of Central Europe.
The height of the body vertically, at the anterior ray of the dorsal,
is equal to one-fifth of the whole length. It descends very insensibly
towards the head, somewhat more abruptly towards the posterior
region ; but as far as the anterior margin of the anal it maintains itself
in proportions which give to the whole of the body a cylindrical
appearance. A considerable inflexion runs along the insertion of the
anal, and beneath the tail, whose height exceeds one-third the
greatest height of the body. The pedicle of the tail is dilated and
subquadrangular.

The head forms one-fourth of the whole length, exclusive of the
lobes of the caudal. The frontal line, at first a little inclined,
appears broken by a slight depression at the top of the posterior
margin of the orbit ; thence it descends somewhat rapidly on the
snout, which is obtuse and rounded, and forms the principal character
of this species.

The lower and upper maxillaries, the intermaxillaries and each
of the palatines have a row of conical and acute teeth. The largest
are on the lower maxillaries and on the intermaxillaries ; they are
very slightly curved inwards at their summit. The teeth of the
palatines must be enumerated next in the order of their relative

334 LAKE SUPERIOR.

size, those of the upper maxillaries being the smallest and the most
curved. The teeth of the vomer are of medium size, between those
just mentioned, and somewhat more curved at their summit ; there
is a row of them on the hinder semicircular margin of the chevron,
then another row on the middle part of the body of this bone. On
the tongue the teeth are disposed in a pair of lateral rows ; they are
as large as on the palatines, and are the most curved of all.

The small ossicles disposed in rows along the inner margin of the
branchial arches are slightly convex within, and finely denticulate
on the outer margin of the curve. On the hinder margin of the
lingual bone, at the symphysis of the three first branchial arches,
there is a small, narrow and elongated shield with card-like teeth.
A similar, but triangular shield is contiguous to the lower pharyn-
geal. Finally, a third shield is applied to the side of the upper
pharyngeal.

The eyes are circular and of medium size. Their diameter is con-
tained six and a half times in the length of the head, about one
diameter and a half from the end of the snout to the anterior margin
of the orbit, and four diameters from the posterior margin. The
suborbital is composed of five pieces, which form an uninterrupted
chain from the margin of the skull to the front of the nostrils. The
first is subtriangular, the summit of the triangle being turned towards
the side of the eye. The form of the second is an elongated
square of which the greatest diameter is in the direction of the length
of the body. The third is more irregular, approaching sometimes to
the form of a protracted lozenge in the direction of the length of the
fish : it borders the lower and hinder outline of the eye. The fourth
is elongated, almost straight, very narrow, and has at its surface a
row of pores ; it attains the anterior line of the eye. Finally, the
fifth is equally perforated, and of a very irregular form ; it protects
the lower margin of the nostrils and rests upon the intermaxillary.
At the anterior and upper margin of the eye is a small superciliary
bone.

The openings of the nostrils are apparently equal, and near each
other, the hinder being somewhat higher ; they are situated at the
height of the eye, and nearer to this latter than to the end of
the snout ; they are protected by two very thin ossicles.

FISHES OF LAKE SUPERIOR. 335

The opercular apparatus differs considerably from that of S. na-
mai/cush ; in the fresh condition it is covered with a thick skin
which hides the outlines of its bones. The preoperculum is long, of
the form of a very opened crescent, placed almost vertically ; its
posterior margin is attenuate and entire ; its lower branch is more
extended than the upper. The operculum of greater height than
breadth, is large and notched at the summit, but without prominent
processes on the rest of its circumference, which is irregularly circu-
lar ; the posterior middle part, however, has a tendency to make a
projection ; the lower margin is denticulate. The suboperculum is
one-third smaller than the operculum, irregularly elliptical, pointed
at the summit, with an ascending ridge in the form of a fish-hook
at its articulation. Finally, the iuteroperculum has the form of a
long square, curved on the posterior side ; its height is contained
twice in its length.

The branchiostegal rays are thirteen in number, their length
diminishing very gradually from the opercular apparatus beneath the
throat, where the last is only one-third smaller than the first. This
latter can scarcely be distinguished from the interoperculum, so thin
and dilated is it ; it is only a little more narrow, and we remark
that it has a tendency to bend itself. The curve is stronger on the
four following, which are still very dilated compared to the eight
remaining, which are not larger than ordinary rays, and flattened,
with a more marked elbow on their extremity of insertion, which,
moreover, is curved inwards.

The fins on the whole are strong and proportioned to the body
which they have to support and to move. The dorsal, which is larger
than in the 8. namaycush, is higher than it is long, and occupies
exactly the middle of the back ; its margins are straight. The
adipose, opposite to the posterior margin of the anal, is narrow, lan-
ceolate, with an elliptical summit turned backwards. The caudal is
ample and slightly furcate, much less furcated than in S. namaycush.
The anal is as high as the dorsal, but not as long as this latter,
though its rays are more numerous ; they are there very dense, and
the three first are shorter than the fourth ; its terminal margin is
straight. The ventrals are inserted beneath the dorsal, vertically,
under the seventh ray ; they do not reach the anus behind ; their

336 LAKE SUPERIOR.

outer circumference is oval. In Salmo namaycush the ventrals are
far more backwards than in S. Siscowet. The pectorals are very
long, yet still they leave a certain distance between their extremity
and the commencement of the dorsal.

Br. 13 ; D. 12 ; A. 12-14 ; C. 6, I., 9, 8, 1., 5, V. 9 ; P. 14.

The scales, generally small, are a little larger on the lower region
of the body behind the ventrals. Their general form is elliptical,
their greatest diameter in the direction of the length of the fish ;
their smallest diameter measures one-eighth of an inch on specimens
of two feet in length. Those of the lateral line are proportionally
more narrow, and perforated with a large canal, which renders this
line very conspicuous. It follows the middle of the body upon the
caudal region and rises gradually in advancing towards the head, so
that in the anterior region it approaches much more to the back than
to the belly.

The color varies according to the feeding ground on which it is
caught, and is brighter during the breeding season, as is gener-
ally the case among all species of this family. The young have
transverse bars, -which disappear \vith their growth, like those of
other species of salmon.

This also is a fish of high and rich flavor, but so fat as to be almost
unfit for food, the greater part of it melting down, as it were, in the
process of cooking. This renders its preservation in alcohol very
difficult, if not impossible. All the specimens which I brought from
our excursion have decomposed. They were caught at Michipicotin,
and occur everywhere along the northern shores. They are particu-
larly abundant about Isle Royale.

COREGONUS, Artedi.

We shall not treat here of the history and the characters of the
genus Coregonus in its whole extent. For this I refer my readers to
the twenty-first volume of the Histoire Naturelle des JPoissons. I
shall merely criticise the North American species, which I have been
enabled to study in nature, refraining from offering conjectures on
those which remain imperfectly known to me. To delay their revision

FISHES OF LAKE SUPERIOR. 337

until we possess original specimens, is the only means of preserving
their nomenclature intelligible.

The reforms we have proposed to introduce among the species
described below, are of a nature to excite the attention of the natur-
alists of this continent, and to induce those who may find them-
selves in favorable circumstances to observe minutely, and to
collect materials which may some day serve as the basis for a special
work on the j^enus.

The Coregonus dupeiformis was described for the first time by
two authors simultaneously, who have each given it a particular
name. The question of priority might be contested ; and what
shows that subsequent authors disagreed on this point is, that some
adopted the name given by Lesueur, others that of Mitchill. Natur-
alists have now agreed to adopt the name dupeiformis, it having
the priority of a few weeks, and being also the more appropriate to
this species; and the figure of the Fauna of New York, though
leaving still much to be desired," is however sufficient to distinguish it
in the present state of science. In the same year, Dr. Kirtland pub-
lished another figure, which appeared in the Journal of the Natural
History Society of Boston, IV., PI. 9, f. 1. It being much inferior
to that of Dr. Dekay, I have omitted it in the synonymy ; it seems
really to me in contradiction with the other quotations. I have cited
the description, because it is literally copied from Lesueur. I should
not be surprised however, if the specimens which Dr. Kirtland has
had under his eye belonged to another species, though it is impossi-
ble to decide this by means of the figure. Richardson also repro-
duced the original description of Lesueur, not having seen the
species himself.

In truth, the history of this species has remained almost what it
was in 1818. Dr. Dekay, who has revised the species in nature,
does not complete its description, limiting himself to a mention of
the most prominent traits. Finally, M. Valenciennes himself is still
more brief. I believe, moreover, that he is mistaken when he con-
siders C. lucidus Rich, as identical with C. dupeiformis. It would
rather be with 0. albus Lesu. that it ought to be compared, and to
which it is nearly related ; but the position o the eye, a smaller

23

338 LAKE SUPERIOR.

mouth, larger maxillaries, and a different conformation of the oper-
cular apparatus, distinguish it sufficiently.

All authors, after Lesueur, have been mistaken in the 0. albus ;
this would not be surprising had they nothing to guide them but the
short description of this author ; but the figure which accompanies it
leaves no doubt about his species, and the most superficial inspection
might suffice to give at least an approximate idea of it. In the
present state of the science I agree that we may confound our (7.
sapidissimus and 0. latior in their full-grown condition ; but where
the question is between so different species as O. albus Lesu., and
those (for we shall see that there are several) which authors have
designated under the same name after Lesueur, we may very
naturally ask ourselves, whether the information given by them has
been drawn from original sources, or has, perhaps, been published
under the belief that the fishes commonly designated under the
name of white-fishes, must all belong to the same species.

There are two groups of Coregoni ; one having the lower jaw
longer than the upper, the other having a squarely truncated snout,
and the upper jaw overlapping the lower. O. albus Lesu. belongs to
the first of these groups, whilst the Coregoni described under the
same name by subsequent authors, belong to the second group. Let
us now review these latter, having no longer to compare them with
the species of Lesueur.

Dr. Richardson has described and figured under the name of O.
albus, a species allied, in certain regards, to our C. sapidissimus and
C. latior ; but I think it cannot be identified either with the one or
the other, due attention being paid to the differences indicated in
our descriptions. Dr. Dekay gives this species as the C. albus in his
New York Fauna ; but not having seen, he says, the species, he
borrows his information from Dr. Richardson.

Another species has been mentioned under the name of C. albus,
by Mr. Thompson. This species is our G. sapidissimus.

A third species has hitherto been confounded with the preceding,
to which it approaches in several respects. This is our C. latior.

Finally, I inquire what may be the O. albus of Kirtland ? The
figure which he gives of it is different at the same time from those
published by Dr. Richardson and Mr. Thompson, so that I do not

FISHES OF LAKE SUPERIOR. 339

know to which of them to refer it. I should not be surprised to find
it the type of a particular species. The details of the head not being
minutely given in the figure, do not allow us to make a direct com-
parison of them.

The presence of small teeth on the surface of the tongue is an
almost universal character in Coregonus, though it is more evident in
the species in which the lower jaw is longer ; this would be another
character of this group, which would allow us to associate with it 0.
Labradoricus and Harengus, which M. Valenciennes was disposed
to discard from it. In the species with a truncated snout, and a
longer lower jaw, we remark that the intermaxillaries have a row of
teeth. These differences seem to me of sufficient value to justify
the formation of two distinct genera for these fishes. I would pro-
pose to preserve the name of Coregonus for those species in which
the snout is prominent, as it was primitively established with refer-
ence to such species in Europe. The name of Argyrosomus might
be applied to the other species, with a truncated snout and a promi-
nent lower jaw.

The species of this continent may be grouped as follows :*

Argyrosomus. Coregonus, proper.
* Coregonus clupeiformis DeKay. * Coregonus sapidissimus Agass.

" lucidus Richards. " albus Rich.

Possessing only a female individual of this species, our description
must not be considered as absolute, and applicable to the males and
young, for their form and general outlines. Dr. Dekay has already
made the observation that the males are more elongated than the
females, and that, besides, the latter are deeper and more compressed;
which is generally the case in the Salmonidae.

The general form is regular, spindle-like, neither thick and short,
nor slender. The sides are much compressed ; the line of the back
is nearly straight, somewhat sloping on the nape and the head as
likewise on the region of the adipose fin, and raised on the caudal.
The curve of the belly is uniform from the lower face of the head to
the termination of the anal ; the lower side of the tail is straight or
slightly concave. The greatest height of the body, taken before the
dorsal, is contained five times in the whole length, including most of
the caudal fin. The thickness is less than half of the height. It is
about the same on the whole abdominal region and the thorax, dimin-
ishing gradually towards the tail.

The head is small, compressed like the sides, flattened above,
rounded below, pointed before. Its length equals the height of the
body, that is to say, it forms one-fifth of the length. The eyes are
large and circular, separated from the extremity of the jaw by a
diameter of their orbit, and by twice and a half this diameter, from
the posterior margin of the opercular apparatus. The nostrils are
nearer to the snout than to the orbit. The opening of the mouth is
of middle size, of a quadrangular form ; the lower jaw considerably
exceeds the upper, and rises slightly at its extremity, which is round-
ed ; its margin contains a few fine indentations, which seem to
indicate teeth ; the intermaxillaries have very fine teeth. The sur-
face of the tongue seems to have two longitudinal rows on its middle
shield, if we can call teeth small acute points. The tongue itself is
pointed, and does not attain the inner margin of the intermaxil-
laries. The maxillaries are elongated, of an oblong form, with entire

FISHES OF LAKE SUPERIOR. 341

margins ; their posterior extremity not attaining a vertical line which
would descend through the centre of the eyeball. The mandibles,
situated on the inner margin of the maxillaries, are small and narrow,
with an undulated outline terminated above by a slender and acute
process. The suborbitaries cover two-thirds of the face.

The preoperculum is concave on the middle of its ascending
branch ; its posterior angle is rounded, and extended to the lower
margin of the face, and, conjointly with the lower branch, nearly
covers entirely the prolongation of the interoperculum towards the
lower maxillary. The part of the interoperculum which remains un-
covered, is triangular ; the upper angle rises before the operculum.
This latter is higher than it is broad above, straight or slightly con-
cave,' rounded behind, oblique and straight on the suboperculum,
which is the most regular of the bones of this apparatus, being arched
on its lower edge, and somewhat more narrow behind than before.

The branchial fissures continue beneath the head, the branchioste-
gal membrane of the right side unites to that of the left on the region
of the isthmus, where they are contiguous, the first jointed beneath
the second. The branchiostegal rays, eight in number, are very
close, flattened, and almost straight.

The scales are proportionally large, of subcircular form, the inner
margin irregular and angular. The largest occupy the middle of
the trunk and the abdominal region, where they measure more than
a quarter of an inch ; they diminish towards the thoracic arch, the
back and the tail, where they are smallest. On the middle line of
the belly their form is much elongated and elliptical. Their termi-
nation is very remarkable on the basis of the caudal, resembling
somewhat the fork of this fin by the concave line they form. The
lateral line is near the middle, rather near to the back, and is slightly
inflected on the abdomen by a very protracted curve.

The dorsal fin, situated on the middle of the back, is much higher
than it is long, and its margins are straight ; its first ray is short
and simple ; the second does not reach beyond two-thirds of the
height ; it is articulated, but not bifurcated. The adipose fin is long
and narrow. The anal, longer and less high than the dorsal, is con-
cave on its terminal margin ; it somewhat exceeds the adipose fin
backwards ; its height somewhat exceeds its length. The caudal is

342 LAKE SUPERIOR.

deeply furcated ; its lobes are pointed. The ventrals are large, tri-
angular, regular, the outer margin somewhat longer than the inner ;
their extremity is not an inch from the anus ; they are inserted on
the lower face of the body, and very near each other ; their base
of insertion is rounded ; the cutaneous prolongation of their upper
margin is much elongated. The pectorals are elongated and pointed.

COREGONUS ALBUS, LeSU.

COREGONUS ALBUS Lesu. Journ. Acad. N. Sc. Philad. 1818, L, 232
(figured.)

The general form is elegantly elongated, lanceolate, with very reg-
ular outlines. The curve of the back is similar to that of the belly,
except that the space on the back, which extends from the nape of
the neck to the dorsal, is more arched, whilst, on the belly, it is most
arched between the ventrals and the anal. However, in young
individuals from five to eight inches long, these two lines present the
greatest uniformity. The body is regularly compressed ; the greatest
height before the dorsal is contained four times and a half in the
length, reckoned from the end of the snout to the end of the scales on
the caudal. The thickness is equal to half of the height.

The head is conical, pointed at its extremity, and more compressed
than the body, attenuated below ; it forms the fifth part of the
length, excluding the caudal. The skull is rather flattened than
convex ; it is sloping as much as the lower surface is raised. The
eyes, very large and circular, are situated at the distance of their
diameter from the end of the snout, and of twice and a half this same
diameter from the posterior margin of the opercular apparatus. The
suborbital bones, very much developed, encroach upon almost the
whole face, of which a very small and narrow space is left bare above
the anterior branch of the preoperculum as far as the posterior ex-
tremity of the maxillaries. The nostrils open on the upper face of the
rostrum, at equal distances from its extremity and the anterior margin

FISHES OF LAKE SUPERIOR. 343

of the orbit. The mouth Is large in comparison to the other species ;
when open, its form is that of a quadrangular tunnel, measuring
seven-eighths of an inch vertically, and one and three-eighths inches
transversely : it contains no teeth. But on the other hand, there are
two rows of rudimentary teeth on the tongue ; in order to see them
the membrane of the surface must be removed. The tongue itself is
narrow and pointed. The lower jaw is longer than the upper ; its
extremity is rounded and slightly raised. The intermaxillaries are
small ; the maxillaries oblong and elongated, attaining, with their pos-
terior extremity, the anterior margin of the eyeball. The labials are
one half smaller, and of the same form, having a small point at their
anterior extremity.

The outer circumference of the opercular apparatus is rounded and
semicircular, and scarcely shows a tendency to undulate in the margin
of the suboperculum. The operculum would be triangular were
it not for the curve of its upper and hinder margin ; the lower mar-
gin, contiguous to the suboperculum, is very oblique. The interoper-
culum attains the lower angle of the operculum ; its hinder angle
is rounded, subtriangular ; its anterior branch is completely covered
by the preoperculum, which is very wide at its angle.

The branchiostegal apparatus is little developed, and arranged as
in C. dupeiformis. There are seven very close, short, and flat-
tened rays.

The scales are proportionally large, easily falling off in individuals
fifteen inches long ; the largest are those covering the sides near the
lateral line, which measure six-eighths of an inch in the longitudinal
direction, and somewhat more than four in the transverse. On the
abdomen the proportions change ; they are somewhat higher than long,
and are sensibly oblong with their greatest diameter oblique. Beneath
the belly they are, as usual, much elongated. The lateral line is near
the middle of the body, somewhat nearer to the back than to the belly :
at its origin it rises above the operculum ; it is straight along the tail.
The termination of the scales on the caudal presents the same pecu-
liarity as in 0. dupeiformis.

The dorsal is on the middle of the back, its height somewhat ex-
ceeding its length, and its upper margin straight. The adipose fin
is oblong, and elongated, exactly opposite to the hinder margin of the

344 LAKE SUPERIOR.

anal. The anal itself is much longer than high, and the disproportion
between the anterior and the posterior margin is greater than on the
dorsal ; the outer margin is concave. The caudal is furcated ; its
lobes are pointed. The ventrals are very near each other, and
shaped as in C. dupeiformis, and the cutaneous prolongation of
their upper margin is long and triangular. The pectorals, little
longer than the ventrals, are oblong and less pointed than in C. clw-
peiformis.

Lesueur did not give the dimensions of his fish : those which I
have procured do not exceed fifteen and a half inches, though I have
seen a numerous series of them. I do not know whether they
attain a larger size.

This species is common about the Pic ; but I have also secured
specimens from various localities along the northern shores of the
lake.

COREGONUS SAPIDISSIMUS, AgaSS.

COREGONUS ALBUS TJiomps. N. H. Verm. 1842, 1., 143, (wood-cut)
( White-fish or Lake shad.^)

"We take as the type of this species the description and the figure of
Mr. Thompson, which though much reduced, gives a clear idea of it.
We have several individuals twenty-two inches in length, the size
of those which Mr. Thompson himself has described. A complete
series of young individuals enables us to give a full description, and
in order to render it more intelligible we shall begin with the adult.

The general form is slender, the sides compressed, the back and
belly prominent. The space contained between the anterior margin
of the dorsal and the occiput is much arched, convex ; and the nape of
the neck itself is sometimes very prominent. From the dorsal the
line of the back descends abruptly on the tail ; it is somewhat de-
pressed immediately behind the adipose fin, and rises somewhat on
the insertion of the canclal. The ventral line is almost uniformly
convex, but the region situated between the ventrals and pectorals is
somewhat more prominent. This line becomes very oblique and
ascendant beneath the thoracic region and the head. The greatest

FISHES OF LAKE SUPERIOR. 345

height of the trunk corresponds to a vertical line along the middle of
the space between the pectorals and the ventrals ; it is contained
about three times in the length, exclusive of the caudal. The
thickness at the middle of the trunk corresponds to the height as one
to two ; it is somewhat less anteriorly, and diminishes gradually
towards the caudal region. The head is proportionally small, com-
pressed laterally, pointed. Its upper surface slopes as much as the
lower rises, so that in adult individuals it appears disproportioned to
the development of the trunk, of which it forms only a very small pro-
portion. Its length, however, is one-fifth of the whole length, the
caudal included. The middle surface of the skull on the suture of
the frontals, is slightly conical, and causes the two halves of the skull
to appear inclined towards the eyes. These latter are large and
subcircular ; the hinder margin of their orbit is at an equal distance
between the end of the snout and the free margin of the operculum.
The suborbital bones cover the whole space between the orbit and
the upper region of the operculum, but leave bare the lower half of
the cheeks ; they form a continuous series below the eyes as far as
the snout, where this latter elongates itself over the labials, which it
receives beneath its lower margin. The nostrils are somewhat
nearer to the orbit than to the extremity of the snout. This latter is
cut obliquely, and slopes over the lower jaw, which shuts within the
intermaxillaries. The mouth is moderate. The intermaxillaries are
small, and occupy only the extremity of the rostrum ; they have a
row of very small teeth, flexible like bristles. The labials are very
short, thin, elongated, and attain the anterior margin of the orbit ;
they have on their termination a small shield, which is bony, pearl-
like and included in the skin. The lower jaw seems to be unprovided
with teeth, at least we cannot observe any either with the magnifying
glass or with the touch. The branches of the lower maxillaries dilate
in the form of a very thin blade, which in the state of rest shuts
itself up under the suborbital bones. At the anterior margin of this
blade we remark a cutaneous expansion, a kind of lip, which is at.
tached to the posterior and terminal margin of the labials, and forms
thus the angle of the mouth. The tongue is short and broad, free
only on its anterior and lateral outline ; its surface, though seeming
to be smooth, has some irregular rows of small asperities, which are

346 LAKE SUPERIOR.

sometimes perceived only after removing the investing membrane.
The operculum is subtriangular and large, when we consider that the
upper and hinder margins pass from one to the other by a curve ;
the lower margin is straight and oblique, and as long as the anterior
margin is high. The suboperculum is arched on its whole circum-
ference, and makes a projection beyond the operculum. The
interoperculurn, almost completely covered by the preoperculum,
presents externally only a small triangular surface, and a small nar-
row band below the lower branch of the preoperculum ; though in
reality, this bone is as long as the suboperculum, but less broad, having
the form of a very acute triangle, of which the summit would be on
the anterior side.

The branchial openings are very ample, and join each other at the
lower surface of the head. The branchiostegal membrane, whose office
it is to shut this fissure conjointly with the opercular apparatus, is
proportionally little developed ; it contains commonly nine, some-
times ten very crowded, flattened and almost straight rays.

The scales are of middle size in proportion to that of the fish. The
largest are situated beneath the belly, the smallest under the throat,
the thoracic -belt and the caudal region. Those of the lateral line
are somewhat smaller than those of the adjacent rows. Their form
is generally subcircular or irregularly quadrangular, but their verti-
cal diameter has a slight tendency to surpass the longitudinal diame-
ter. This peculiarity is especially striking on the abdominal region,
where really the scales are oblong and of a height sensibly greater
than their length ; at the same time that their outlines become more
regular and nearly oval. Their imbrication has even here some-
thing peculiar in being less close ; the rows appear independent, and
give to the fish a barred aspect. The outlines of those of the late-
ral line are the most irregular. The outer margin is in all more or
less circular and entire. The lateral line itself is nearly straight and
nearer to the back than to the belly ; it begins from the upper angle
of the operculum and extends itself to the middle of the caudal.

The anterior margin of the dorsal fin corresponds to the middle of
the space contained between the extremity of the snout and the basis of
the caudal ; the fourth and fifth rays are the longest ; the first two
short and rudimentary spines are applied against the third, which is

FISHES OF LAKE SUPERIOR. 347

simple but articulated, and almost as long as the following ; being
higher than it is long, this fin has a triangular form on account of its
posterior margin, which is low and inclines on the back. The adi-
pose is broad, covered with small scales on its basis and opposite to
the posterior half of the anal, of which it does not attain the extrem-
ity. The anal, as long as it is high, occupies the middle of the space
between the anus and the basis of the caudal ; it has, like the dorsal,
two spinous rudimentary rays in its anterior margin, and one soft ray
more. The caudal is furcated and ample ; small scales encroach
upon its basis. The ventrals are large, with their terminal margin
straight ; they are almost as long as the dorsal is high ; the anterior
margin opposite to the twentieth ray of the dorsal contains a small
spinous rudiment hidden beneath its membrane ; the cutaneous appen-
dix of the upper margin is very small. The pectorals are elongated,
spindle-like, and proportionally small.

During the early age, when its size does not exceed eight inches,
the slender form is the predominant character of this fish. The line
of the back and that of the belly being then very little prominent, and
the outline of the head passing in direct continuation to that of the
body, there results a harmonious whole in the proportions of these two
regions. The compression of the body is already very marked ; the
head is already pointed and forms one-fifth of the whole length, not in-
cluding the caudal fin. The rostrum is truncated but rounded, and
exceeds the lower jaw. The nostrils are placed at equal distances
between its extremity and the eye. The greatest height slightly ex-
ceeds the length of the head. The characteristic form of the fins may
already be remarked ; there being one ray more or less in the one or
the other of the fins. The ventrals are placed somewhat more for-
wards relatively to the dorsal, their anterior margin being perpendicu-
lar to the fifth or sixth of its rays. The same complete development
is also observed in the opercular apparatus ; the operculum alone pre-
sents this slight difference, that its height sometimes exceeds a little
the length of its lower margin ; the breadth of the suboperculum is also
subject to some variations. The scales at this period are thin and fall
off easily, but we may recognize already the different characters which

348 LAKE SUPERIOR.

we have signalized above. The lateral line is straight and nearer to
the back than to the belly. But as soon as the individuals attain a
length of ten inches, the head becomes declivous, the nape of the
neck swells, the back rises, the belly becomes more prominent ; but
the general form is still slender, the head is in harmonious propor-
tion with the trunk, of which it forms already one-fifth of the length,
including half of the caudal. The rostrum becomes somewhat more
prominent and more abrupt. The height of the body exceeds how-
ever already the length of the head.

When individuals attain fourteen inches the back and the nape of
the neck are very convex, and the head very declivous, the belly
prominent, and from this moment the head appears disproportioned to
the trunk, and is found to form exactly one-fifth of the whole length,
the caudal excluded, as we have seen in the adult. The height of
the body is contained four times in its length. The scales are
still thin and fall off easily, but they already begin to be more adhe-
rent than during the preceding stages. The middle surface of the
tongue is armed with small asperities as in the adult ; and the intermax-
illaries have also that row of fine teeth which we have indicated
above.

This species is the common white-fish of Lake Superior, of which
so large numbers are caught and salted every year. It is one of the
most palatable fishes of the freshwaters of the American continent.
It is found in large shoals all over the lake.

COREGONTJS LATIOR, AgaSS.

Hitherto confounded with the preceding, with which it has a great
affinity, this species differs, however, sufficiently to justify its separa-
tion, as I hope to show. Possessing young and adult individuals, I
shall follow in relation to them the method which I have already
adopted, pointing out first the difference existing between adult speci-
mens, and finally adding the peculiar traits of the young. I will
here mention that the adults differ in appearance less than the young,
— among which, the difference at first sight is most striking.

The adult individual which I have before me measures nineteen
inches. The general form reminds us of that of C. sapidissimus. As

FISHES OF LAKE SUPERIOR. 349

in this latter, the back is arched from the occiput, but the curve is
more uniform, the nape of the neck being less prominent, and the
belly also less swollen. The body is thicker and stouter than in the
O. sapidissimus, compressed, fusiform ; the greatest height, which is
measured vertically at the anterior margin of the dorsal, is contained
four times in the length, the caudal included. The lines of the back
and belly come near each other on the tail, without abrupt transition ;
they continue on the head, without rising much on the lower face,
and without lowering much on the upper face, though the skull is
depressed and slightly sloping. The head, which is thicker and
stouter, forms one-fifth of the whole length, including the caudal.
It is less pointed than in the preceding species, and the rostrum
more obtuse, less exceeding the lower jaw. The mouth is somewhat
larger, but constructed in the same manner ; that is to say, the
ascending branches of the lower maxillary shut themselves up beneath
the suborbital bones, and there is a cutaneous appendix at the anterior
margin, and a kind of lips, which form the angles of the mouth by
uniting with the labials. These latter are broader than long, passing
beyond the anterior margin of the orbit. Their terminal extremity
has likewise the long and pear-like shield, which we have indicated in
O. sapidissimus. The lower jaw, again, is surrounded with a folded
lip, imitating a border of fringes. We have remarked no trace
of teeth on the intermaxillaries, and without deciding upon their
absence, they were at least obliterated so as to render them doubtful.
The tongue is broad and shows no trace of asperities at its surface.
The eyes are large, almost circular, and placed in the same relative
position. The nostrils are nearer to the orbits than to the extremity
of the rostrum. The suborbitaries present no remarkable difference,
unless it be, perhaps, that they encroach less on the cheeks.

In the opercular apparatus, we remark that the operculmn is
rather quadrangular, and the suboperculurn more contracted at its
posterior extremity, which renders its lower margin more oblique.
The iuteroperculum is somewhat more uncovered.

The fissure of the gills is the same, but the branchiostegal appara-
tus is more developed and the rays more bent ; their actual number
is eight.

The scales are somewhat larger than in the preceding species, and

350 LAKE SUPERIOR.

present about the same general form, but their height surpasses
their length. Generally more uniform on the different regions, they
are, however, larger on the middle of the trunk, those of the middle
line being in 'other respects smaller than the adjacent ones, as is
the case for the most of the species. Those of the abdomen affect
not a linear disposition, independent from the whole, but all appear
as uniformly imbricated. Beneath the belly and the tail they elon-
gate themselves to the form of an ellipsis with tortuous outlines.
The lateral line, slightly arched, follows the outlines of the back,
to which it is nearer than to the belly. The fins on the whole are
much more developed than in the C. sapidissimus ; their general
form and their relative position are sensibly the same. We remark,
however, that the height of the dorsal is greater in proportion to its
length, and its posterior margin is straighter. The adipose fin,
equally covered with small scales on its basis, is opposite the termina-
tion of the anal. This latter is triangular, as long as it is high, but
less raised than the dorsal. The caudal is deeply furcated. The
ventrals, broad and oblong, are rounded on their terminal margin,
and contain the strongest rays. The pectorals are elliptical, and
longer and broader than in the preceding species, and from the
stouter form of the body their terminal extremity is nearer to the
ventrals.

Whoever doubts the validity of this species should only cast a
glance on two series of young individuals belonging to both species.
We have noted above the peculiar traits of the C. sapidissimus, and
it will be remembered that we have insisted upon their slender and
elongated form. The most striking contrast exists when we compare
them with the short, high and stout form of this species.

When this fish has attained the size of seven inches, the height,
which exceeds the length of the head, is contained four times in the
length of the body, the caudal excluded. The sides are much com-
pressed ; the thickness is only one-third of the height. The structure
of the head, the form and the development of the fins, are in perfect
conformity with the adult. We observe that the rostrum, which is
truncated, scarcely exceeds the lower jaw. The form of the buccal

FISHES OF LAKE SUPERIOR. 351

opening is quadrangular as in the adult. The intermaxillaries have
a row of very fine teeth ; there are teeth even on the margin of the
lower jaw, but more difficult to perceive even with the magnifying
glass. The surface of the tongue is prickled with small, very acute
asperities, like the teeth of the intermaxillaries. The eyes are very
large ; the distance which separates them from the end of the snout
does not equal their diameter ; the nostrils occupy the middle of this
space.

The scales, which are stronger and larger, as we have already
seen, easily fall off; we may already signalize in them the same pe-
culiarities which we have seen in the adult. The lateral line is
straight and approaching slightly more to the back than to the belly.

When ten inches in length, this fish acquires an increasing height ;
the height, taken before the dorsal, is contained exactly four times in
the length, the caudal included, and the head has almost the propor-
tions of the adult. The body is very compressed and flattened ; its
thickness is contained three times and a half in the height. The snout
is somewhat more prominent, as in the preceding age, though renicViv
ing more truncated and shorter, as in the O. sapidissimus. The
scales grow gradually firmer ; those of the upper half of the body
somewhat shorter than those of the lower half. The fins themselves
grow more prominent. The species is common along the northern
shore of Lake Superior, where it is found with C. sapidissimus. I
have collected a large number of specimens at the Pic.

COREGONUS QUADRILATERALIS, Richards.

Among the Coregoni collected at Lake Superior there is one very
similar to C. quadrilateralis of Dr. Richardson, though I have yet
doubts as to its identity. The question can only be decided by
comparison of specimens from the localities where the author of the
Fauna Boreali-Americana collected his. I have already noticed
slight differences in the scales, in the structure of the fins, in the
opercular and branchiostegal apparatus, and in the proportions of the
body ; differences which depend, perhaps, upon the age and size, and
•which I have not been able to verify in all my specimens, they being
below the dimensions which Richardson assigns to his species. I

352 LAKE SUPERIOR.

have endeavored to compare them by means of reduction, but I soon
perceived that I could not arrive in this way at a precise determina-
tion, especially as the proportions of the different regions of the figure
of Richardson do not fully agree with the measures which he gives of
them in the text. The formula of the fins which I have taken from
an individual of fourteen inches, is :

Br. 6 ; D. Ill, 11 ; A. II, 10 ; C. 7, I, 9, 8, I, 6 ; V. 11 ; P. 16.

The scales of the lateral line, though smaller than the adjacent
rows, do not appear to me so absolutely truncated as Dr. Richardson
expressly says they are in his species. Their size on the sides equals,
if it does not surpass, four-eighths of an inch, and on a surface of an
inch square we may count as many as eight. This fact has appeared
to me the most prominent.

Richardson reports that when Cuvier sent him the specimens
which he had submitted to his examination, the label indicated that
he, (Cuvier,) had a related species from Lake Ontario, but we do
not find it mentioned by M. Valenciennes in the Histoire Naturelle
des Poissons. It is perhaps to this species of Lake Ontario that our
specimens ought to be referred. Sir John Richardson, having seen
recently the specimen described above, has himself offered doubts re-
specting its identity with his O. quadrilateralis.

CYPRINOIDS.

This is a numerous, but well circumscribed family, whose striking
peculiarities are very obvious. I am not aware that any of these fishes
have ever been noticed in the waters of the southern hemisphere ;
nor do they extend anywhere far beyond the limits of the temperate
zone, as it is well ascertained that they are most numerous in the
rivers and lakes of Central Europe and Central Asia and Northern
America. Indeed, it is so much their natural home, that they do not
seem to occur in the northernmost freshwater streams, nor any-
where in the tropics, except in very great altitudes, where recently
a few have been found in the Andes. The sea is almost entirely
destitute of fishes of this family ; a few species, hoAvever, occur in
brackish waters.

The family of Cyprinoids affords another example of the fact, that

FISHES OP LAKE SUPERIOR. 353

•

the species of animals are circumscribed within narrow limits in their
geographical distribution. From the great number which have already
been described, it is plain that almost every lake and every river
has species of its own ; but, nevertheless, there is a great uni-
formity among these fish all over the world ; for the carps of China
and those of Europe are very similar ; so are the little white-fishes
of the Nile and those of other basins. But however uniform
these fishes may be in the main, we cannot help observing that
among them there are peculiar groups, located in particular parts
of the world, for instance, the Catostomi, all over the freshwaters of
America. The small bearded species are very numerous in Europe,
and, in general, in the Old World ; species with beards occur there
more extensively than on the American continent.* Again, the types
with a large dorsal are extensively distributed, but are almost all extra
American. The species which occur at great altitudes, as those from
the lakes of tropical America, are so peculiar as to differ decidedly
from all other Cyprinidae, being devoid of ventral fins. In Lake Supe-
rior and the other Canadian lakes there is a considerable variety of
these fishes, — Catostomi mixed with European types, and a genus
which has only American representatives.

The little group of Cyprinodonts, which have so universally been
connected with Cyprinoids, will be found to differ more from Cypri-
noicls than has been supposed. We need only compare the structure
of their mouths to be satisfied of the difference. There are no repre-
sentatives of that type in Lake Superior.

How far it might be advisable to subdivide this family into small
groups according to their structural differences, remains to be ascer-
tained. The Catostomi, for instance, are very remarkable for the
large opening in the centre of their skull, and for the peculiar arrange-
ment of the teeth in the pharyngeal bone.

REINICHTHYS, Agass.

I propose to include in the genus Rhinichthys small Catostomi,
whose essential character is, as the name indicates, to have a conical

* I would mention, as particularly characteristic of the Old "World, the genera Barbus,
Cobitis, and the allied types.

prolongation of the rostrum. The mouth is small ; the lips which
border it are much reduced, smooth, never carunculated, and do
not extend themselves on the lower jaw under the form of lobes.
This character is well represented on figure 2 of PI. 2. At the
angles of the mouth, the upper lips bend slightly forwards to join the
middle of the branch of the lower maxillary ; they here form a
small tunnel, on whose outer margin is a small barbel, sometimes
very difficult to recognize. To this genus we must refer the Lends-
cus atronasus (Cyprinus atronasus Mitch.^) and L. nasutus Ayres.
Though the first of these species has not the character of a very
prominent rostrum, the structure of the mouth, and the presence
of the barbel, justify this approximation.

There are still other species of this genus found in the United
States, yet imperfectly known, which will hereafter also take their
place here. Anatomical study will doubtless reveal other characters
than those which external conformation already gives, and will also
teach us the value of this singular group in the family of Cyprinoids.
At present I cannot help considering the Rhinichthys of North
America as a diminutive of the group of the Labeos of Africa and
the East Indies.

RHINICHTHYS MARMORATUS, Agass.
PI. II., figs. 1 and 2.

This species is one of the largest of the genus, at least, of those
which are as yet known to us. The form is elongated, subcylindrical,
compressed. The tail preserves just proportions with the trunk ; its
two margins are almost straight. The ventral line is a little convex,
and rises abruptly at the insertion of the anal. The back is feebly
arched from the dorsal fin to the nape of the neck, where the slope
continues rapidly from the skull to the snout. The head is entirely
smooth ; it is small, conical, and well proportioned to the body, in
whose whole length it is contained four times. The upper surface is
rounded ; the eyes are of medium size, and situated near the upper
margin of the face, at about an equal distance from the end of the
rostrum and the upper angle of the operculum. The nostrils are

FISHES OF LAKE SUPERIOR. 355

very large and near the orbits. The rostrum exceeds the lower jaw
by the whole length of the opening of the mouth. This latter is
small, semi-elliptical, when the jaws are closed ; when opened, it has
the form of a crescent whose circumference would be formed bv the

»/

upper jaw, having below, as a base, the elliptical and rounded outline
of the lower jaw. The barbel is about a twelfth of an inch long.

The face and the opercular apparatus are smooth like the head.
The preoperculum is hidden beneath the fleshy cheeks. The oper-
culum is large, concave on its anterior margin, rounded on the
upper ; the lower is straight and oblique, beneath which is the thin
and narrow subopercular lamina. The interoperculum is triangular
and more robust. The branchial fissures are small, and extend but
little to the lower surface of the head, which gives to the isthmus the
form of a triangle. The branchiostegal membrane contains three
thin rays, of about equal length, bent and flattened.

The dorsal fin occupies exactly the middle of the whole length of
the fish ; its form is quadrangular, higher than long, and has nearly
straight margins. The caudal is obtusely notched, its lobes are
rounded. The anal, situated at a small distance backwards from the
dorsal, is narrow and elongated ; its outer circumference is rounded.
The ventrals are inserted somewhat before the dorsal ; they are
small fins of an oblong form, whose extremity reaches to the anus.
The pectorals are placed very low, have an elliptical form, and are
more elongated than the ventrals.

Br. 3 ; D. II, 9 ; A. II, 8 ; C. 5. I, 9, 8, 1, 4 ; V. 8 ; P. 14.

The scales are small and subcircular ; the concentric and radi-
ating stride are easily seen with a lens. Points of black pigment are
distributed on their posterior half, and give to the surface of the
body a punctulated appearance. The lateral line is in the middle ;
it is only feebly inflected on the abdomen.

The ground color is a reddish brown mottled with black, orange
and dark green. The black marbling is predominent. A large spot
of this color occupies the basis of the caudal, where it radiates on
the rays of this fin. The lips, the margin of the branchiostegal
membrane, the basis of the pectorals, ventrals and anal are of an
intense orange-red, which prolongs itself on the rays. The ground of
the fins is light orange.

CATOSTOMUS, Lesueur.

The study of the species of the genus Catostomus has become
quite as difficult as that of the genus Leuciscus, and for the same
reason ; the multiplicity of species. There are about thirty described
or mentioned, very few of which are accessible for comparison.
Hence, we are left, either to identify species which have only dis-
tant analogies, or to separate, on the other hand, some which have
the closest affinities. Which of these two obstacles is the most inju-
rious to science ? Doubtless the first ; since it leaves science in a
state of equivocal stability, during which no advance is attempted,
satisfied, as we are then, with our present attainments.

In endeavoring to determine the different Catostomi from Lake
Superior, I began by comparing them with species already known
from the same geographical zone to which they would have the
nearest relations. One had been known for three quarters of a cen-
tury as an inhabitant of the gulfs of Hudson's Bay, and was described
by Forster under the name of Cyprinus Catostomus, which, forty-
four years later, became the type of the genus Catostomus, with the
specific appellation of C. Jludsonius, the author of this reform not
having known the fish otherwise than through the description and
the figure of Forster.

In 1823, that is to say, about fifty years after Forster, Dr. Rich-
ardson gave a detailed description of the C. Hadsonius. He described
also another under the specific name of Forsterianus, and referred
to it as a synonymous variety of the preceding, indicated by Forster
himself. His specimens were from Lake Huron and from Slave
Lake.

Among the species of Catostomi which I have brought from Lake
Superior, there are two which have a very great analogy, in their
general traits, with C. ffudsonius and Forsterianus. However, in
comparing them attentively and singly with the descriptions of Dr.

FISHES OF LAKE SUPERIOR. 357

Richardson, I was convinced of some differences, respecting the first,
which I consider as specific. Respecting the second, the question be-
comes more difficult to solve, as Dr. Richardson had specimens from
two very different localities, from which his description was made.

This complication caused me to hesitate for a long while respecting
these species ; and even now, though describing the second species
under a new name, I am still in doubt upon the following points : Are
there really two species of Catostomi with red bands on the sides ?
This would not be extraordinary, if we do not allow specific diagnoses
to rest upon color. As soon, however, as the existence of two species
is demonstrated by ultimate researches, it is evident that that of Lake
Huron will be the same as our C. aurora, whilst that of Slave Lake
will be the C. Forsterianus, the same which Forster had in view.

However, upon consulting the original Memoir of Forster, I am
almost tempted to consider his second variety as the very species I
describe hereafter, under the name of C. Forsterianus, and which,
as we shall see, is nearly relatad to G. Hudsonius. It has that red
tint of the lateral line, with the same general ground color. If
that be the case, the name of Forsterianus would be ill applied, for
the name would remind us of one species, whilst the description would
apply to another.

CATOSTOMUS AUREOLUS, Lesu.

I cannot do more than mention this species, as I possess only a
few specimens, and all very young, between three and four inches
long. The general characters of the species are, however, already
well indicated upon them. A thick and stout head, almost as high
as long, truncated in front ; the considerable development of the
operculum at the expense of the suboperculum ; the sides, the scales,
their uniformity upon all the regions of the body, and their rhom-
boidal form, such are the traits which characterize it.

The species would thus extend farther northwards than has been
known heretofore. It is, however, still important to verify the
fact, either by comparing young C. aureolus of Lake Erie with these,
or by procuring large specimens from Lake Superior, to compare
them with specimens of the other lakes.

358 LAKE SUPERIOR.

CATOSTOMUS FORSTERIANUS, Agass.

I possess a complete series of individuals of this species, from the
size of eleven inches up to seventeen. My description was made
principally from the largest, to bring it nearest to that of (7. Hud-
sonius ; but I must, at the outset, remark that the characters no-
ticed are the same in all. Not possessing a specimen of 0. Hudso-
nius, I have referred to the description Dr. Richardson has given in
establishing the points of comparison.

The general form of the body is very regular ; the dorsal and
ventral lines circumscribe an elongated oval, approaching to a cylinder
towards the head, and to a parallelogram along the tail. The greatest
circumference taken on the line of the greatest height, that is to say,
before the dorsal, is nine inches and a half. The sides are compressed ;
the body passes to the head, or, we might rather say, the head passes
to the body, without any enlargement on the nape of the neck.
The greatest height of the body does not become double the
greatest thickness, this latter being taken at the very origin of the
trunk ; thence it diminishes gradually and insensibly towards the
caudal region, and the proportion begins to become progressively
stronger in favor of the height from the posterior margin of the
dorsal.

The head itself is very smooth, and covered with a thick skin ; it
is rather conical than quadrangular, on account of the declivity of
the upper surface, which continues from the nape of the neck to the
obtuse and rounded snout. It forms about the fifth part of the
whole length, or rather less ; its height forms three-quarters of its
length, in which the breadth between both eyes is contained twice.
The eyes are subcircular, and situated near the upper surface of the
head ; the anterior margin of their orbit is at equal distances from
the end of the snout and the posterior extremity of the operculum ;
in other terms, the diameter of the orbit is contained twice in the
space which separates it from the margin of the operculum, and thrice
in that which extends between it and the rostrum. The nostrils are
large, and at a distance of one-fourth of an inch from the anterior
margin of the orbits ; their structure varies little in different species.

FISHES OF LAKE SUPERIOR. 359

The mouth is placed immediately beneath the extremity of the ros-
trum ; it is of medium size, very protractile ; its opening is subcircular,
and easily receives the largest finger beyond the first phalanx. Its
lips are carunculate ; the upper is thin, and of equal breadth on the
whole circumference of the jaw ; it dilates itself from the angle of
the mouth, to pass to the thickened and rounded lobes, with fringed
circumference of the lower jaw ; these fringes are equally visible
on the margin of the upper lip ; the two lobes are united on the
symphysis of the jaw, by a narrow cutaneous slip ; the caruncles
which cover their surface are scarcely more marked than those of
the upper lip. On the head we remark several rows of pores similar
to those of O. Hudsonius and other species. These rows are per-
fectly distinct in individuals preserved in alcohol. One of them is the
continuation of the lateral line of the body ; it passes along the upper
margin of the operculum, descends beneath the orbit, and terminates
on the end of the snout, describing some undulations on its pas-
sage. The second row begins at the nostrils, and terminates on the
occiput, a little before the union of the head with the body, on which
point of union we observe a third single row, united transversely
by its two extremities to the first double row. Finally, a fourth row
is situated upon the face, and follows the outer margin of the pre-
operculum.

The opercular apparatus differs from that of 0. Hudsonius, as
described by Dr. Richardson, in two of its bones, the preoperculum
and the interoperculum. This latter, in the species which is here
referred to, has exactly the length of the suboperculum, though it is
more robust and of more irregular form. It has a median carina on
its anterior angle, whose extremity reaches that of the preoperculum
in contact with the lower maxillary ; the posterior part, contiguous to
the operculum and suboperculum, is triangular, and rises to one-third
of the height of the anterior margin of the operculum. The pre-
operculum is more slender, more elongated, and narrower than the
interoperculum ; its form is that of a very opened crescent.

The branchial fissures are very large, and somewhat approximated
on the isthmus, where the membrane passes to the integuments of
the abdomen, appearing somewhat like a transverse furrow.

The intestinal canal measures twice the length of the body. The

lower pharyngeals form a complete ring around the oesophagus.
Each bone, taken by itself, resembles in its form a sickle ; that is to
say, a crescent with a stalk. With this short, robust and flattened
stalk the two bones unite, by means of a muscular bridge, which
modify constantly the separation of which they are capable. The
crescent presents two distinct sides ; one, the inner, is compact,
rounded and smooth, and is only the continuation of the stalk;
the other, or outer, is widened, embracing only the circumference of
the crescent ; it is composed of vertical laminae, of which the teeth
are the continuation, with the exception of two lower ones, which
are implanted on the very body of the bone. There are about thirty
teeth ; the lower are much developed, strong, and compressed later-
ally, surmounted by a crown which slopes over their inner side.
From the middle of the crescent the teeth diminish abruptly towards
its summit, and are reduced to feeble laminae, which are lost in the
body of the bone, which is also subject to a gradual diminution from
the stalk to its upper angle.

The air bladder is composed of two compartments ; the anterior 13
pear-shaped, and not quite half the length of the posterior, whose
form is cylindrical.

The color of this fish is bluish gray on the back, the head and the
sides ; upon the sides an orange-colored red tint, with a very fine
reflection, combines itself with the main color ; the belly and the
lower side of the head are whitish. The pectoral and ventral fina
are gray, on an orange-colored ground ; the caudal has the tint of
the back, as also the dorsal ; the anal is sometimes whitish, like the
belly, sometimes gray like the ventrals.

This species is very common along the northern shores of Lake
Superior.

FISHES OP LAKE SUPERIOR. 361

We have stated above, when speaking of the generic characters,
the reasons which have induced us to change the name of this
species, and to work out again its synonymy. Therefore, nothing
more remains to be said on this point, and we proceed to give a full
description of it, also comparing it with the above species, and regret-
ting that we have been unable to compare it in nature with the O.
Hudsonius. As described by Dr. Richardson, his (7. Forsterianus,
which is our Aurora, is rather compared with that species than
described in detail, and as these two species are very different from
each other, the comparison has not been made in its most minute
peculiarities.

The body is subcylindrical, compressed. Its general form, less
thick and stout than in the preceding species, presents the same
regularity of outlines, and the same harmony of the regions among
themselves. The greatest height corresponds also to the anterior
margin of the dorsal, and forms the fifth of the whole length, the
caudal excluded ; this height forms five-sevenths of the greatest
thickness of the body, which corresponds to the immediate back of
the head. The diminution is gradual towards the tail. The head
forms exactly the fifth of the whole length, and it is of course con-
tained four times in that of the body, the caudal included. It is
almost as compressed as in the preceding species, but less rounded
on the upper surface, more elongated, more conical, and the rostrum
more prominent. The skull is, however, declivous. The nostrils are
very large. The position of the eyes, opposite the rostrum and the
margin of the operculum, has the same relations as in the preceding
species. The mouth is larger, and seems to be placed more back-
wards, on account of the developement of the nose, but the upper lip,
when we extend it, easily reaches to its extremity. The lips are
more developed, and covered with more prominent caruncles. The
two lobes especially are more extended, and are not at all attached
to each other on the maxillary symphysis, as they are in the preced-
ing species, being in this respect more independent of each other.
(PI. 2, f. 4.)

The surface of the head is covered with a smooth skin, through
which the rows of pores open, upon the whole, similar to those which
we have described in the preceding species.

362 LAKE SUPERIOR.

The opercular apparatus is smaller and more convex than in the
preceding species, and all the bones are so, proportionally, I having,
however, been careful to take two individuals of the same size for the
purpose of comparison. The operculum is as broad as high, though
narrower at the upper margin than at the lower, which is oblique ;
the posterior margin is almost straight. The suboperculum is more
regular, on account of its lower margin being less convex. The
interoperculum is less extended on its posterior extremity, which
emits no processus along the anterior margin of the operculum. The
outer surface is very convex, and almost smooth. The preoperculum
is longer and more slender than the interoperculum, and proportion-
ally broader than in the preceding species.

The branchial fissures are large also ; the branchiostegal membrane
is strong and thick ; it contains three rays. The dorsal fin is quad-
rangular, its posterior margin equals in height two-thirds of its anterior
margin, where we observe two or three small rudimentary rays,
without articulations. Its upper margin is almost straight or subcon-
cave. The anal is long, and attains the base of the caudal in the
male, whilst it is shorter in the female ; its anterior and posterior
margins are parallel on the first two-thirds ; beyond which they
approach each other to form a triangle, and to terminate the fin in
a more or less obtuse point. The caudal is notched ; the scales
advance more on the base of the lower lobe, which predominates
slightly over the upper ; but this character is not constant ; I have
even observed it only on the single individual which I have had
figured ; there is one, sometimes two, rudimentary rays at the ante-
rior margin. The ventrals are broad and expanded, like an equi-
lateral fan in the male ; while in the female the inner margin is
shorter, which changes the aspect of the outer circumference, which
is straight and more uniform in the male. Generally, we observe
the rudiments of a ray at the anterior margin, which corresponds to
the fifth ray of the dorsal, the rudiments excluded. The pectorals
are long and of an irregularly elliptical form, or oblong, sometimes
pointed at their terminal extremity. The anterior ray is strong and
robust ; the fifth is the largest.

FISHES OF LAKE SUPERIOR. 363

The scales, very small at the anterior part of the trunk, increase
in size towards the tail, without, however, attaining to the dimensions
of the species above mentioned, nor even to those of C. Hudsonius.
This increase of the scales from the head to the tail is real, and agrees
with the imbrication. Their form is irregular and very variable, though
we may say that they are generally oblong, of greater length than
height, with convex margins, which are undulated, and never parallel
and straight, like the upper and lower margins of the scales in the pre-
ceding species. Now and then we may find a few circular ones, but
they are exceptions. Those which cover the shoulders are still much
larger than those situated between the pectoral fins on the lower sur-
face of the abdomen. The lateral line is median, slightly inflected on
the abdomen before the dorsal. It rises a little on the pedicle of the
caudal. The abdominal walls are covered with a blackish pigment.
The length of the intestinal canal is contained twice and a half in that

O

of the body. The pharyngeal bones, though having the same struc-
ture as in the preceding species, are, however, much more slender,
and their teeth are much more feeble, thinner, and sharper on their
extremity.

The air bladder, equally divided into two compartments, presents
this difference, that, instead of being cylindrical, the posterior com-
partment terminates in a pointed cone. The size and the relative
proportions remain almost the same in the two species.

The color is an olive yellow, very dark on the back and head,
where it passes to the green on the sides. Following the course of
the lateral line there is a band of a very brilliant carmine red, without
precise outlines circumscribing it. In the females the red is less
lively, and the belly remains white. The dorsal, caudal, and pec-
toral fins are colored like the back ; the ventrals and the anal like
the abdomen, but of a more intense yellow. The rays are of an
olive-colored green.

This species occurs frequently along the northern shores of Lake
Superior. I secured, however, most of my specimens at the Pic.

GENUS ALBURNUS, Heck.

This genus has been known only in the Old World, until I dis-
covered the species described below, which was caught at the Sault

364 LAKE SUPERIOR.

of St. Mary. The species described before are about equally di-
vided between Europe and Syria. The principal character of the
genus is to have the mouth opening upwards, the lower jaw exceed-
ing a little the upper (PL 3. figs. 2 and 3.) The dorsal is narrow ;
the anal slightly broader, The body is compressed.

ALBURNUS RUBELLUS, Agass.
PL III., figs. 1-3.

This is as yet the only species of the genus found in North America.
The body is compressed ; its form is elegant, slender, the back some-
what more convex than the belly ; the tail is contracted. The great-
est height of the body corresponds to the anterior third, or the region
situated between the pectorals and the ventrals, and is contained
eix times in the length, exclusive of the caudal fin. The head, small,
conical and compressed, like the sides, is somewhat less than the
fifth of the whole length. The upper surface continues the declivous
line of the back towards the end of the snout. The eyes are large
and circular, approaching the upper region of the head, and at an
equal distance from the end of the snout and the posterior extremity
of the opercular apparatus. The suborbital ossicles are three in
number ; two are contiguous to the posterior and lower margin of
the orbit, the other at the anterior margin, covering the whole space
between the nostrils and the lower maxillary. The nostrils, propor-
tionally large also, are nearer to the eyes than to the extremity of
the snout, and opening into two apparently equal orifices. Fig. 2,
which represents the upper surface of the head, shows only the ante-
rior orifice, the posterior being covered by the intermediate mem-
brane which separates them from each other. The mouth is
moderately opened ; its angles reach behind a vertical line which
would pass before the eyes. The lower jaw slightly exceeds the
upper (figs. 2 and 3.)

The preoperculum is rounded at its posterior margin. The lower
margin of the operculum is straight and oblique. The subopercu-
lum is narrow, and terminates behind in a point ; its upper margin,
contiguous to the operculum, is straight ; its lower margin forms a
slight elliptical curve. Scarcely can we distinguish the lower mar-

FISHES OP LAKE SUPERIOR. 365

gin of the interoperculum, this "bone being hidden behind the pre-
operculum. The branchiostegal rays, three in number, are flattened
and excessively thin, almost equal in form and in size, and slightly
arched.

The dorsal fin is higher than long, and situated about on the middle
of the back. Its anterior margin is twice as high as its posterior.
The upper margin is straight. There are ten rays, of which the
anterior is short and undivided ; the bifurcation is repeated to the
third degree on the central rays. The caudal is long and furcated ;
the rays are twice bifurcated ; the largest only have slight indica-
tions of a three-fold division. The anal, placed behind the dorsal, is
broad, but less high than this latter ; its margins are straight ; it
contains eleven rays, of which two are rudimentary and undivided at
the anterior margin. Those of the centre show the traces of a
triple bifurcation. The ventrals, narrow at their base, extend con-
siderably at their circumference, which is rounded ; they are situated
before the dorsal, and contain eight rays, the first being simple, the
five following subdivided to the third degree. The pectorals,
narrower and more elongated than the ventrals, are inserted behind
the suboperculum at a small distance from this bone. There are
eleven rays ; the first does not bifurcate at all, though it is articu-
lated ; the six following are articulated on their last third only ; the
five remaining are very short.

The scales are of medium size, and about equal on all regions of
the body. Their form is subcylindrical ; the concentric and radiating
stride are visible only under the microscope. The lateral line is
slightly inflected from the upper angle of the opercular apparatus
upon the abdomen, to rise again opposite the dorsal, and thence con-
tinues in a straight line towards the tail, following the middle of the
sides.

The back is of a yellowish green, with the outlines of the scales
black. The upper surface of the head and the snout are of a darker
tint. The face, the opercular apparatus and the sides have a bril-
liant silvery reflection, with a more marked median band. There
are some reddish spots on the face and the opercular apparatus,
fading sometimes into a uniform reddish tint all over the head and

shoulders. The iris is gold-colored ; the fins are of a uniform color,
a transparent, pale yellow.

Fig. 1 represents the fish of natural size. Figs. 2 and 3 are en-
larged, to show the characters of the mouth and the jaws.

This species is very common at the Sault of St. Mary ; specimens
were also obtained from the Pic.

GOBIO PLUMBEUS, Agass.

This species is widely distinct from Grobio cataractce, the only
species of that genus found in North America which has hitherto
been described. The body is elongated, subcylindrical, compressed ;
its greatest length is about seven inches. The head is contained
somewhat more than four times in this length, and the height of the
body forms exactly the fifth of it. The back is very slightly convex;
the belly describes a very marked curve ; the tail beyond the anal fin
straightens almost abruptly. The head itself is conical, irregularly
quadrangular, the upper surface being very flattened, sometimes
even concave on the middle line, and the lower surface plain. The
eye is situated at the upper region of the face ; its diameter is one
fourth of an inch. The nostrils are large also, and situated in circu-
lar cavities at the upper part of the face. The anterior opening
is oblong ; its canal is oblique from behind forwards ; its posterior
margin, when extended, forms a cover to the second opening, which
is the largest, perforated like the first, and placed a little more out-
wards. The snout is flattened. The upper jaw exceeds the lower,
and thus removes the mouth to the lower side of the head, At the
angles of the mouth there is a very small barbel, still more slender
than in the 6r. cataractce. It needs a very attentive examination to
notice it.

The posterior margin of the operculum is notched in the form of a
small crescent at whose margin is a process of this bone. The lower
margin is oblique and slightly concave, bordered on its whole length
by the suboperculum, a small, thin, narrow and elongated lamina.
The interoperculum and the preoperculum are hidden beneath the
fleshy skin of the cheeks. The branchiostegal membrane contains
three rays ; it is continued upon the opercular valve.

FISHES OP LAKE SUPERIOR. 367

The dorsal is situated exactly on the middle of the whole length,
somewhat farther back than in Cr. cataractce ; it is higher than long.
The caudal is notched ; its lobes are pointed. The anal is somewhat
smaller than the dorsal, but it has the same form. The ventrals,
situated somewhat in front of the dorsal, are rounded on their cir-
cumference. The pectorals are narrower than these latter ; they
are also more elongated and more rounded on their circumference ;
their form is oblong.

The scales are large ; we can scarcely count sixty rows from the
gills to the caudal ; somewhat oblong on the sides, they are subcir-
cular on the back and belly. We readily perceive with the magni-
fying glass the concentrical and radiating strice. The lateral line is
deflected on the abdomen into an open curve, and recovers its direct
line beyond the dorsal, towards the tail. It is almost central in its
whole course.

The head, the back, and the upper half of the sides are ash-gray.
A narrow lead-colored band extends along the upper side of the lat-
eral line. The abdomen is yellowish white, interspersed with small
gray points on the scales. The lower side of the head and belly is
of a uniform color. The dorsal, caudal, and pectorals are gray, the
ventrals and the anal yellow. The largest specimens of this species
are from Lake Superior. We have also a few from Lake Huron.

I am well aware that the position of this species in the genus Gobio
is not natural, as it has neither the particular cut of the outline of
the head which characterizes the European species of Gobio, nor
their narrow dorsal, nor their projecting barbel, nor their pharyngeal
teeth, but I am unwilling to establish a new genus for it before I
have organized the American Cyprinidne more extensively. I will
only add that were it not for the barbel this species might be very
properly placed in the genus Leuciscus. But the European Leucisci
have not rudiments of such appendages on the sides even of the
mouth ; while all the species of Cyprindo of North America, which
have been referred to the genus Leuciscus, have, as far as I know,
such short barbels. I am therefore inclined to believe that these
species will have to be removed from that genus, Leuciscus, and

368 LAKE SUPERIOE.

constitute by themselves a distinct genus, to which my G-obio plum-
beus will also belong, as it is not to be separated generically from
Leuciscus pulchellus and other American species.

LEUCISCUS FRONTALIS, Agass.

PI. III., fig. 4.

At first sight this species reminds us of L. cornutus of New Eng-
land, to which it bears a close resemblance. Its general form is
short and stout. Its sides are much compressed. The back is very
convex. The height of the body is proportionally great, and is con-
tained only four times in the whole length, from the anterior extremity
of the head to the termination of the caudal. It has thus a corpu-
lent form, and is even higher than L. cornutus. The tail also
loses its dimensions less abruptly. The head itself participates of
the abbreviated form of the body, being somewhat less than a quarter
of its length. Its upper surface is rounded, very declivous, and de-
scends abruptly on the snout, which renders it very obtuse, rounded,
and, as it were, prominent. The eyes are large and circular, pro-
portionally larger than in L. cornutus, and approach less to the top
of the head. They are situated but little nearer to the end of the
snout than to the posterior margin of the opercular apparatus. The
lower margin of their orbit corresponds to a horizontal line traced
along the middle of the face. The nostrils open by a double opening
in a circular depression situated before the eyes, and nearer to these
latter than to the terminal margin of the head. The anterior
opening, which is the smallest and of subcircular form, is bordered
behind by a small membrane which applies itself like a cover on the
posterior opening, rendering its form crescendo. The mouth is of
medium size, but shorter cleft ; its angles attain a vertical line which
would descend from the nostrils; it is terminal and oblique; the
lower jaw is somewhat shorter than the upper.

The opercular apparatus has nothing remarkable. The bones
which compose it are all hidden beneath a thick skin through which
we scarcely distinguish their outlines. All are rounded on their
outer margin, and give to the extended outline of the whole opercu-

FISHES OF LAKE SUPERIOR. 369

lum the form of a crescent on whose convexity the branchiostegal
membrane is continued to the upper margin of the operculum.

The branchial fissures are large. There are three strongly devel-
oped branchiostegal rays, flattened and arched. The two outer on
each side may approach very near to each other on the middle line
of the lower surface of the head, where they are parallel for a short
distance. The branchiostegal membrane is endowed with great
elasticity.

The rays of the centre of all the fins are bifurcated to the third
degree. In front of the dorsal, of the anal and of the ventrals we
remark the rudiment of a spinous ray, often very difficult to recog-
nize. The following ray is never bifurcated, though distinctly articu-
lated as the remaining ones ; this is also the case with the ray of
the anterior margin of the pectorals, and with the great outer ray
of the lobes of the caudal, which for this reason is stouter.

The anterior margin of the dorsal fin corresponds exactly to the
middle of the length of the body, excluding the caudal ; so that it
extends behind the most prominent part of the back, along the curve
of the posterior half of the body ; its length nearly equals the height
of its anterior margin ; its upper margin is very slightly rounded.
The anal is both lower and shorter than the dorsal, but its length
equals its height. Its outer margin is almost straight. The caudal
is admirably regular ; its posterior margin' is notched by a subcircu-
lar crescent ; the ventrals are oblong, rounded, when extended ; their
outer circumference equals three widths of their base ; their poste-
rior extremity passes somewhat beyond the anus. The pectorals
have precisely the general form of the ventrals, but they are larger ;
their terminal extremity is almost contiguous to the base of insertion
of the ventrals.

The scales cover more than half of each other by imbrication ; they
are oblong in the vertical direction, and seen in their natural posi-
tion, they represent lozenges which vary a little according to the
regions ; the largest occupy the middle region of the body as far as
the pedicle of the tail ; but on this latter region they are broader
in proportion to their height. On the back they have almost the
size and the form of those of the tail. On the belly they are much

370 LAKE SUPERIOR.

smaller and subcircular. The lateral line curves slightly on the
abdomen as far as the height of the anterior margin of the dorsal,
whence it continues almost directly towards the tail, approaching
nearer, however, to the lower line of the body.

Small circular shields with depressed surface, surmounted with
very small conical and acute points, cover the surface of the head,
the snout and the back, as far as the dorsal fin. A row of five or
six of the largest border the lower jaw ; those of middle size cover
the extremity of the snout and the space situated before the eyes.
On the back they are excessively small.

The head and the back are of a bluish black, the sides and the
abdomen of a gold-colored yellow, everywhere with a metallic reflec-
tion. The fins are of uniform color and participate of the tint of
the regions to which they belong.

LEUCISCUS GRACILIS, Agass.

There is still another Leuciscus which, at first sight, one might
be disposed to confound with L. cornutus or with the frontalis
above described. And it must be confessed that it has much anal-
ogy with those two species, between which it must be placed in a
natural series.

In a family so numerous in species as that of the Cyprmidse, it is
only by minute study that we can succeed in making out the history
of each of them. Here, as in Europe, the species, though belonging
often to different genera, gradually pass from one genus to another,
in their general appearance ; the type of the family, that of the
genus itself, seems to predominate in all ; and by reason of the
multiplicity, and also the diversity of forms under which these
characters manifest themselves, the species appear to be mere varie-
ties. These difficulties occur also, in all genera which have numer-
ous species in other families of this and other classes, but, far from
impressing naturalists merely with the monotony to be overcome,
thev should render them attentive to the most minute details which

«/

characterize, in a permanent manner, natural groups in the animal
kingdom. In the case of this species and the two others mentioned

FISHES OF LAKE SUPERIOR. 371

in connection with it, I am satisfied that they should constitute a dis-
tinct genus, characterized chiefly by their scales, which are so much
higher than long, besides the particular form of their head and body
and their pharyngeal teeth. There are some more species of this
genus yet undescribed, which have been discovered in Pennsylvania
by Prof. Baird ; but I do not know one from Europe.

Though the length of this species is the same as that of L, fron-
talis, its general form shows a marked diiference. It is fusiform,
rather slender but very compressed, the curve of the back being
very elliptical, and the abdomen making a stronger projection.
The height is somewhat less than a quarter of the whole length.
The head is small and conical ; its upper surface rather flattened
than convex, with a less marked declivity. The anterior part, less
developed than in the L. frontalis, renders the head more pointed,"
though the snout be obtuse. The eyes are somewhat larger, and
nearer the upper margin of the skull. The face is less developed,
both jaws are of equal length. The opercular and branchiostegal
apparatus are less robust. The head forms about the fifth of the
entire length, and this slight difference in the proportions, when
compared with L. frontalis, accounts for the differences of the
general form, which we have noticed above. Again, as the conse-
quence of a more slender body, smaller fins are required to sustain
it, and there being space for separation between them they become
more distant from each other. Thus is the distance enlarged
between the extremity of the pectorals and the base of the ventrals,
and between the extremity of the ventrals and the anus. All the
fins, taken together, are smaller than in L. frontalis. Thus the
pectorals and the ventrals are less widened, while the length is the
same. The dorsal is higher than it is long ; the anal lower than the
dorsal, but also higher than long. The caudal is narrower, a natural
consequence of a smaller tail.

The rays of the dorsal, caudal, and pectoral fins, present bifurca-
tions of the second degree only ; slight indications of three-fold
bifurcation are observed on the central rays of the ventrals and anal,
but with less regularity than in the preceding species.

The scales are larger than those of L. frontalis, and are less

extensively imbricated, showing, however, the same proportions on
the different regions, which we have given for the preceding species.
The lateral line is apparently the same ; only the curve inflected on
the abdomen seems wider.

The back and the head are greenish-brown ; the lower face of the
head and the abdomen are of a very pale golden yellow, with a very
brilliant silvery reflection of the scales. The operculmn is gold
colored. The rays of the dorsal, caudal, and pectoral fins, have a
gray tint on a yellowish ground. The ventrals and the anal are of
a golden yellow, like the abdomen.

The head is smooth ; we notice only on the space between the eye
and the occiput some rudiments of tubercles hidden beneath the
skin, perceptible only to the touch.

This species is distinguished from L. cornutus, not only by the
color of its fins and the absence of armature on the head, but also
by differences in the general form and structure of the fins, anal-
ogous to those which we have pointed out in L. frontalis.

The resemblance of this species to the Clupea is only superficial,
and does not require a long examination to be refuted. With the
exception of the general outline, it has not one of the essential char-
acters of organization of that family. The external conformation of
the mouth could not leave us for a moment in hesitation as to which
natural group it belongs. It is of the family of Cyprinidae, where
it has been placed by the author of the Zoology of New- York.
Already DeWitt Clinton, though arranging it in the genus Clupea,
entertained some doubts in this respect, on account of the absence of
a ventral serrature.

The species is tolerably well described by the authors whom we
have just cited, so that we have only to refer our readers to them.

FISHES OF LAKE SUPERIOR. 373

We must, however, remark that the figures which they give of it are
rather incomplete. The oldest is still the best for the general out-
lines, and the species is there more easily recognized than .by that of
the Fauna of New York, where the fins are too stiff and too recti-
linear, and the scales drawn in an inverse direction from what they
are in nature, the posterior margin being turned towards the head.

The formula for the fin rays is as follows :

Br. 3; D. II. 9; A. II., 9 ; C. 4, I. 9, 8,1., 4; V. 8 ; P. 15.

A very slight difference in the dorsal and anal may be noticed,
but we consider it of little importance here. Their rays bifurcate
to the third degree, with a few unsymmetrical indications of a
three-fold bifurcation on one of the rays of the anal, and on some of
the central ones of the lobes of the caudal. The rays of the pecto-
rals subdivide only once. As for the branchiostegal rays, we find
only three of them, though DeWitt Clinton has counted four ; per-
haps he counted the suboperculum. Dr. Dekay does not mention
them. There is also something to be corrected respecting the lat-
eral line ; the former says it is obsolete ; the latter describes it
as straight. On the individuals which we have had under notice,
it is almost median ; arising from the upper angle of the opercu-
lum, it is deflected upon the abdomen to rise again gradually beyond
the dorsal fin, and finally to extend straight towards the extremity
of the tail.

From Lake Superior and Lake Huron. Very common about
Fort William and the Pic.

This is another form of the group of Leucisci, of which there is
no representative in Europe. It is likely to become the type of a
distinct genus ; for it has many striking peculiarities. I have, how-
ever, refrained from establishing it until I shall have ascertained
whether the specimens found in different localities are specifically
identical or not.

Such a critical revision of the fishes of Lake Superior, and the
other great Canadian lakes, was the first necessary step in the inves-
tigation I am tracing, in order to ascertain the natural primitive
relations between them and the region which they inhabit. Before

374 LAKE SUPERIOR.

drawing the conclusions which follow directly from these facts, I
should introduce a similar list of the fishes living in similar latitudes,
or under similar circumstances, in other parts of the world ; and more
particularly of the species of Northern Europe. But such a list, to
be of any use, should be throughout based upon a critical compara-
tive investigation • of all the species of that continent, which would
lead to too great a digression. The comparison of the freshwater
fishes of Europe, which correspond to those of North America, has
been carried so far, that I feel justified in assuming, what is really
the fact, that all the species of North America, without a single ex-
ception, differ from those of Europe, if we limit ourselves strictly to
fishes which are exclusively inhabitants of freshwater.

I am well aware that the salmon which runs up the rivers of
Northern and Central Europe, also occurs on the eastern shores of the
northern part of North America, and runs up the rivers emptying into
the Atlantic. But this fish is one of the marine arctic fishes, which
migrates with many others annually further south, and which migra-
tory species is common to both continents. Those species, however,
which never leave the freshwaters, are, without exception, different
on the two continents. Again, on each of the continents, they differ
in various latitudes ; some, however, taking a wider range than
others in their natural geographical distribution.

The freshwater fishes of North America, which form a part of its
temperate fauna, extend over very considerable ground, for there is
no reason to subdivide into distinct faunce the extensive tracts of land
between the arctics and the Middle States of the Union. We notice
over these, considerable uniformity in the character of the freshwater
fishes. Nevertheless, a minute investigation of all their species has
shown that Lake Superior proper, and the freshwaters north of it,
constitute in many respects a special zoological district, sufficiently
different from that of the lower lakes and the northern United States,
to form a natural division in the great fauna of the freshwater fishes
of the temperate zone of this continent.

We have shown that there are types, occurring in all the lower
lakes, which never appear in Lake Superior and northwards, and
that most of the species found in Lake Superior are peculiar to it ;
the Sahnonidse only taking a wider range, and some of them covering

FISHES OF LAKE SUPERIOR. 375

almost the whole extent of that fauna, while others appear circum-
scribed within very narrow limits.

it

Now, such differences in the range which the isolated species take
in the faunae is a universal character of the distribution of animals ;
some species of certain families covering, without distinction, exten-
sive grounds, which are occupied by several species of other families,
limited to particular districts of the same zone.

But, after making due allowance for such variations, and taking a
general view of the subject, we arrive, nevertheless, at this conclu-
sion ; that all the freshwater fishes of the district under examination
are peculiar to that district, and occur nowhere else in any other
part of the world.

They have their analogues in other continents, but nowhere beyond
the limits of the American continent do we find any fishes identical
with those of the district, the fauna of which we have been re-
cently surveying. The Lamprey eels of the lake district have very
close representatives in Europe, but they cannot be identified. The
sturgeons of this continent are neither identical with those of Europe
nor with those of Asia. The cat-fishes are equally different. We
find a similar analogy and similar differences between the perches,
pickerels, eelpouts, salmons, and carps. In all the families which
occur throughout the temperate zone, there are near relatives on the
two continents, but they do not belong to the same stock. And in
addition to these, there are also types which are either entirely peculiar
to the American continent, such as Lepidosteus and Percopsis, or
belong to genera which have not simultaneously representatives in
the two worlds, and are therefore more or less remote from those
which have such close analogues. The family of Percoids, for in-
stance, has several genera in Europe, which have no representatives
in America ; and several genera in America which have no repre-
sentatives in Europe, besides genera which are represented on both
continents, though by representatives specifically distinct.

Such facts have an important bearing upon the history of creation,
and it would be very unphilosophical to adhere to any view respect-
ing its plan, which would not embrace these facts, and grant them
their full meaning. If we face the fundamental question which is at
the bottom of this particular distribution of animals, and ask ourselves,

376 LAKE SUPERIOR.

where have all these fishes been created, there can be 1)ut one answer
given which will not be in conflict and direct contradiction with the
facts themselves, and the laws that regulate animal life. The fishes
and all other freshwater animals of the region of the great lakes,
must have been created where they live. They are circumscribed
within boundaries, over which they cannot pass, and to which there
is no natural access from other quarters. There is no trace of their
having extended further in their geographical distribution at any
former period, nor of their having been limited within narrower
boundaries.

It cannot be rational to suppose that they were created in some
other part of the world, and were transferred to this continent, to
die away in the region where they are supposed to have originated,
and to multiply in the region where they are found. There is no
reason why we should not take the present evidence in their distri-
bution as the natural fact respecting their origin, and that they are,
and were from the beginning, best suited for the country where they
are now found.

Moreover, they bear to the species which inhabit similar regions,
and live under similar circumstances in Europe and Asia, and the
Pacific side of this continent, such relations, that they appear to the
philosophical observer as belonging to a plan which has been carried
out in its details with reference to the general arrangement. The
species of Europe, Asia, and the Pacific side of this continent, cor-
respond in their general combination to the species of the eastern and
northern parts of the American continent, all over which the same
general types are extended. They correspond to each other on the
whole, but differ as to species.

And again, this temperate fauna has such reference to the fauna
of the Arctic, and to that of the warmer zones, that any transposition
of isolated members of the whole plan, would disturb the harmony
which is evidently, maintained throughout the natural distribution of
organized beings all over the world. This internal evidence of an
intentional arrangement, having direct reference to the present geo-
graphical distribution of the animals, dispersed over the whole surface
of our globe, shows most conclusively, that they have been created
where they are now found. Denying this position were equivalent

FISHES OF LAKE SUPERIOR. 877

to denying that the creation has been made according to a wise plan.
It were denying to the Creator the intention of establishing well
regulated natural relations between the beings he has called into
existence. It were denying him the wisdom which is exemplified in
nature, to ascribe it to the creatures themselves, to ascribe it even
to those creatures in which we hardly see evidence of consciousness,
or worse than all, to ascribe this wonderful order to physical influences
or mere chance.

As soon as this general conclusion is granted, there are, however,
some further adaptations which follow as a matter of course. Each
type, being created within the limits of the natural area which
it is to inhabit, must have been placed there under circumstances
favorable to its preservation and reproduction, and adapted to the
fulfilment of the purposes for which it was created. There are, in
animals, peculiar adaptations which are characteristic of their species,
and which cannot be supposed to have arisen from subordinate influ-
ences. Those which live in shoals cannot be supposed to have been
created in single pairs. Those which are made to be the food of
others cannot have been created in the same proportions as those
which feed upon them. Those which are everywhere found in innu-
merable specimens, must have been introduced in numbers capable of
maintaining their normal proportions to those which live isolated, and
are comparatively and constantly fewer. For we know that this har-
mony in the numerical proportions between animals is one of the great
laws of nature. The circumstance that species occur within definite
limits where no obstacles prevent their wider distribution, leads to the
further inference that these limits were assigned to them from the
beginning, and so we should come to the final conclusion, that the
order which prevails throughout the creation is intentional, that it is
regulated by the limits marked out on the first day of creation, and
that it has been maintained unchanged through ages, with no other
modifications than those which the higher intellectual powers of man
enable him to impose upon some few of the animals more closely
connected with him, and in reference to those very limited changes
which he is able to produce artificially upon the surface of our globe.

DESCRIPTION OF SOME NEW SPECIES OF REPTILES FROM
THE REGION OF LAKE SUPERIOR.

HYLODES MACULATUS, Agass.
PI. VI., figs. 1, 2, 3.

Tins species is so characteristic as to leave no difficulty in distin-
guishing it from those already known belonging to the same genus.
Its form is narrow, elongate ; and its head smaller, in proportion to
the body, than in any other species. The length of the head is con-
tained twice in the length of the body, thus forming one-third of the
whole length. The body is oblong, rounded, somewhat broader than
high, tapering towards its posterior extremity. The head is ellipti-
cal, tapering towards the snout, somewhat distinct from the trunk by
a slight contraction of the neck ; its greatest width is behind the
eyes ; its upper surface is depressed so that the head appears rather
flat. The eyes, of a medium size, are turned upwards near the mar-
gin of the head, but are hardly prominent. The nostrils are lateral,
and very near the extremity of the snout. The tympanic circle
is small, and near the angle of the mouth. The mouth is widely
split ; the lower jaw is overlapped by the upper, and the snout
slightly prominent. The palatal teeth are arranged in pairs, upon
two small, very narrow bones ; they are extremely minute. Those
of the upper jaw, still less developed, occur only on the middle third
of its arch. The tongue is broad, and fills the whole floor of the
mouth ; it is free upon two-thirds of its posterior extremity, the
margin of which is obtusely bilobed ; the anterior margin and the
sides are hardly free.

REPTILES OF LAKE SUPERIOR. 379

The limbs are very slender ; the fingers very slim, and free for
their whole length. The carpus and tarsus are hardly broader than
the forearm and leg. The posterior extremities exceed the length
of the body by the length of the longest finger. All the fingers are
turned in one direction, bent outwards. The anterior limbs, half as
long as the posterior, have the two outer toes turned outwards, while
the two others are arched inwards.

The upper surface of the head is smooth, as are also the back and
the legs ; but the sides are covered with minute cutaneous tubercles,
which extend over the whole lower surface of the body, where they
increase in size ; they extend, also, over the thigh and forearm ; the
lower jaw and extremities of the limbs, alone, being perfectly smooth
underneath.

The color is of a bluish gray, irregularly speckled with small black
dots, which are partly oblong, partly circular, and very well circum-
scribed in their outlines, so that they show distinctly, notwithstanding
the slight difference in color. The lower surface is of a yellow-
ish white, dark upon the sides, lighter and purer under the head and
along the margin of the lower jaw. A very narrow white band
extends along the margin of the upper jaw, as far back as the inser-
tion of the arm, upon which it encroaches somewhat.

Figs. 1, 2, represent the species of the natural size ; the first, in
the natural attitude of the animal ; the second, as seen from below.
Fig. 3 represents a tadpole, remarkable for the great length the tail
still preserves, the legs being already very far advanced in their
development. Whether they undergo their metamorphoses in one
season, or spend the first winter in an intermediate state between
their larval and adult form, has not been ascertained.

RANA NIGRICANS, Agass.
PI. VI., figs. 4, 5.

This species is intermediate, with reference to its size and the
development of its limbs, between R. clamitans and R. Tialecina.
It differs from both by its color, and by the form of its legs ; the hind
foot being more extensively palmate, and their membrane extending

380 LAKE SUPERIOR.

to the base of the last fingers. The fingers, however, are compara-
tively more slender, and those of the anterior foot more unequal
when compared to each other.

The head is rather prominent, the snout, however, being rounded.
The nostrils, which are very small, open at its extremity. The eyes
are circular, and of medium size, slightly prominent. The upper
eyelid rises to the greatest height of the head. The tympanic circle
is very large, and very near the orbit. The mouth, widely split, is
provided with acute teeth upon the whole margin of the upper jaw.
There is also a small group of teeth, in pairs, upon the palatal bones.
The tongue is broad, oblong, pear-shaped, lining the whole floor of
the rnouth from the symphysis of the lower jaw ; it terminates back-
wards in two obtuse lobes.

The body is proportionally long, ovate, the head forming one-third
of the whole length. A cutaneous keel, of the same color as the
main hue of the back, extends on both sides from the posterior angle
of the orbit to the anus. The posterior limbs are longer than the
whole body by the whole length of the feet. The thighs are com-
paratively thick and short, The anterior limbs bear the same pro-
portion to the size of the whole body that are usually observed in
the various species of frogs. Figs. 4 and 5 give, not only an accurate
idea of the general appearance of the animal, but the proportional
thickness and length of the toes are drawn with the greatest
minuteness.

The largest specimens I have collected are about one-fourth larger
than the figures. The color is of a blackish brown upon the whole
upper surface of the body, head and limbs. Irregular, deep black
spots, of an angular form, are dispersed over this whole surface ; they
are very small upon the head, but larger upon the back, and largest
upon the hind le^s. In large specimens, the general color is more
uniform, somewhat darker, and the spots less distinct. The whole
lower surface is either uniformly whitish, or with a slight yellowish
tint towards the hind extremity, and frequently with small blackish
or brownish spots along the sides. The outline of the lower margin
is bordered with white. Specimens of this species were caught in
various localities along the northern shores of Lake Superior.

REPTILES OF LAKE SUPERIOR. 381

CROTOPHORUS.
PI. VI., figs. 6 to 8.

I abstain from giving a specific name to this species, from fear of
adding a useless synonym to its nomenclature. It is, indeed, very
closely allied to, and probably identical with 0. tergeminus. Its
head, however, is rather elliptical than triangular, and the spots
which cover it differ, as may be seen on comparing our figure with
that of Dr. Holbrook.* The snout is truncate. Having no authentic
specimen of 0. tergeminus to compare with mine, I shall only point
out the differences I have noticed between my specimen and the de-
scription and figure of Dr. Holbrook, leaving it to future comparisons
to settle the question of the specific identity or difference.

The general color is the same as that of 0. tergeminus, but the
two brown bands which exist along the neck on each side, and con-
verge upon the back, are shorter. The bands of the same color, which
arise from the eyes, extend beyond the angle of the mouth, and
nearly meet the other bands, where they unite with the first spot on
the back. The width of these bands covers three rows of scales.
The white band below this is much narrower, and covers but one
single row of scales, and is bent at the angle of the mouth. Along
the back there are thirty oblong transverse spots, deeply emarginate
on the anterior side, and slightly concave on the posterior side back-
wards. They appear like a pair of spots united. Upon the tail
there are five quadrangular, oblong, transverse spots, in advance of
the caudal plates. Upon the sides there is a double row of smaller
spots, of an oblong or subcircular form, varying in size, and alternat-
ing with each other, while in C. tergeminus there is only one small
lateral row. The lower surface of the body is mottled with black and
white, with very minute gray dots. There are one hundred and
thirty abdominal plates, apparently broader than those of C. tergemi-
nus ; and, in addition, in advance of the anus, they are of a semicir-
cular form. The caudal plates are twenty-eight in number, twenty-
five of which are entire, and three, in advance of the rattle, bilobed.

* North American Herpetology, TO!. III., PI. 5.

382 LAKE SUPERIOR.

The lobes of the rattle have the same dimensions as those of C.
tergeminus. The whole length of the body is two feet two inches ;
the head measures one inch and a quarter ; the tail, three inches
and five-eighths of an inch. There are other slight differences in
the proportional length of the body and of the tail, corresponding
to the differences noticed in the greater number of caudal plates
and the greater width of the abdominal plates.

The specimen was caught on the southern extremity of Lake Huron.
Besides those species, the following reptiles occur about Lake
Superior :

Tropidonotus sirtalis,

" erythrogaster,

" a species allied to rigidus, from Lake Huron,

Bufo Americanus,
Rana halecina,
" sylvatica.

These three species occur as far north as Neepigon Bay, and a
circumstance, which has struck me very forcibly, is the remarkable
size of the specimens observed in these high latitudes.

Plethodon erythronotus Bd.

Menobranchus maculatus. This species does not properly occur in Lake
Superior, but is found in Muddy Lake, below Sault St. Marie.

No turtles are found any where on the northern shores of Lake
Superior, as far as I know.

REPORT OF THE BIRDS COLLECTED AND OBSERVED AT

LAKE SUPERIOR,

BY J. E. CABOT.

THE striking scarcity of birds and quadrupeds about the lake has
already been noticed in the Narrative. In the case of the granivo-
rous and frugivorous species, this might be accounted for from the
scarcity of their proper food. To the insectivorous birds, however,
this reasoning certainly could not apply. One would have expected
to find the warblers, especially, breeding in abundance in this
region. But the only birds that could be called tolerably abundant
(except in special localities) were Zonotrichia pennsylvanica, and in
a less degree, Parus atricapillus and Ampelis cedrorum. Some-
thing, no doubt, must be attributed to the season, many birds having
passed further northward, and others being engaged in incubation.
Then all birds are more silent at this season, and less inclined to loco-
motion. On the other hand, we found a great abundance and
variety of birds at the Sault, much greater than would be found in
Massachusetts at that season. And whenever we came to a trading
post, we found a great difference in this respect, although the In-
dians, whether from scarcity of food or from wantonness, destroy
great numbers even of the smaller species. It would seem, that
apart from a more abundant supply of nourishment, the neighbor-
hood of man is in some way attractive to birds, — partly perhaps
from the greater freedom of such situations from beasts and birds of
prey. As to the water-birds, the nature of the country would at
once indicate that none but piscivorous species were to be expected.
In the annual migrations, it is said large numbers of ducks, and
particularly of geese, alight, for a day or two, in the streams and

384

LAKE SUPERIOR.

pools of the shore. But the deep, cold waters of the lake, permitting
no growth of water-plants, except occasionally in a sheltered cove,
possess no attractions further. Accordingly, the only water-birds we
saw were Larus argentatus, Colymbus glacialis and Mergus cucul-
latus, all which we usually saw in small numbers every day, and
one specimen of Colymbus septentrionalis. In the neighborhood of
Detroit we saw black terns in abundance, and heard that some
of the light-colored species bred about St. Joseph's Island, but we
saw none of them beyond the St. Glair.

Seeing the importance that is beginning to be given to even
minute details of geographical distribution, I have subdivided the fol-
lowing list of species observed, so as to present first the species of most
extensive range, and afterwards those of more confined localities.

Body black above. Antennae black, annulated with white, and
rufous at the tip. Wings yellowish white ; the anterior pair dusky
on the front edge and base ; tip, beneath, pale yellow, with dusky
veins. Under side of the hindwings pale yellow, with broad,
dusky veins, and a saffron-yellow spot on the humeral angle.

The tip of the forewings is often marked with two or three little
dusky stripes, in the males. The dusky veining of the under side of
the hindwiugs is less distinct in the females than in the other sex,

LEPIDOPTERA OF LAKE SUPERIOR. 387

and is sometimes entirely wanting. Specimens of the females have
been seen, though rarely, with one or two dusky spots on the upper
side of the forewings, towards the outer margin.

The eggs of this insect are pyriform, longitudinally ribbed, and
of a yellowish color. The larva is pale green, very minutely
sprinkled with darker dots, and with a darker dorsal line. It grows
to the length of one inch and a quarter. Its natural food is un-
known, but it is found abundantly on the leaves of the mustard,
turnip, radish, cabbage, and other cultivated olcraceous plants, to
which it is often very injurious. The pupa is pale green or white,
regularly and finely spotted with black. There is a conical projec-
tion on the front, and a securiform one on the thorax ; and the sides
of the body are angular and produced in the middle. Length of the
pupa eight-tenths of an inch. The pupa state lasts about eleven
days in the summer, and continues through the winter ; there being
two broods of the larva in the course of one season.

This species rarely extends further south than the latitude of New
Hampshire. It has not been figured before. Mr. Kirby's Pontia
casta may, perhaps, be only a variety of it.

above the eyes on the sides of the thorax, where it is margined
above with black. Palpi white below. Forewings with a black
spot at base and another adjacent to a white dash within the middle
of the outer edge ; a flexuous buif-colored stripe, beginning near the
base of the inner margin, indented externally, extends to the tip, and
is bounded within by a dark brown tapering stripe. Hindwings
blackish, or dusky brown, with a broad sinuous rosy band including
a deep red spot, and uniting with a white one near the inner angle.
Fringes of the hind wings, and inner edge of the fore wings white.
Abdomen with a dorsal series of six white dots ; two black and two al-
ternating white bands on each side of the base, and two narrow trans-
verse white lines near the tip ; ventral segments edged with white.
Legs brown ; the tibiae edged externally with white.

This species, which occurs abundantly in New Hampshire, was
taken on the northern shore of Lake Superior, and is now figured
for the first time. It is the American representative of Deilepliila
Grain. Mr. Kirby's D. intermedia, which has the stripe on the
fore wings of a pale rose-color, and wants the dorsal series of white
dots, may possibly be a local variety of D. Chamcenerii. The larva
of our species lives on the Epilobmm angustifolium. It is bronzed
green above, and red beneath, with nine round cream-colored spots,
encircled with black on each side, and a red caudal horn.

LEPIDOPTERA OF LAKE SUPERIOR. 389

Olive-drab ; head very small, and without a prominent crest ; an-
tennas of the males transversely biciliated beneath. Forewings
scalloped, with a transverse sinuous pale line near the base ; a
whitish comma-shaped stigma on a broad undulated dark olive-colored
central band, and two transverse undulated lines towards the tip ;
under side purple in the middle of the disk. Hindwings purple in
the middle and at base, with a transverse black spot, and an abbre-
viated dusky blue band near the anal angle. Body very robust, and
with the legs immaculate.

One of the largest species of the genus. A single male was taken
on the northern shore of Lake Superior in the summer of 1848, and
a fine female was captured in Cambridge, Mass., on the 20th of
July, 1849, which have afforded the means for a more full and cor-
rect description than has heretofore been given. This species
appears to be rare, and has not before been figured. It is the
representative of the European &'. Tilice and Quercus.

Only two specimens of this fine insect have fallen under my obser-
vation. They differ much in size and color. The smallest, appa-
rently a male, was taken in Cambridge, Mass., many years ago.
When at rest, the wings are very much deflexed, and form a steep
roof over the back. The body is light brown ; the forewings are
of a very pale ashen brown color, variegated with darker clouds and

near the base, at the inner angles of the discoidal cells ; the anterior
spot being round and the posterior and larger one triangular. The
hindwings are light ashen brown at base, passing into dusky ochre-
yellow. The large specimen is a female, and was taken by Profes-
sor Agassiz on the northern shore of Lake Superior. The body
is of a dusky ochre-yellow color, tinged on the sides and on the legs
with red. The forewings are light rosy buff, with brownish ochre
clouds and bands, two silvery spots near the base, and a whitish dot
near the tip. The hindwings, above, and all the wings beneath, are
of a deep ochre-yellow color, tinged with red.

The empty pupa-skins of this or of an allied species are sometimes
found on our sea-beaches.

on the thorax, and the black band on the hindwings. The situation
of this band is not so far back as the black spots found on the hind-
wings of the allied species. The banded hindwings, with the en-

from the Arctia Americana, a description of which is here added for

This pretty Geometer has the form of Ennomos (Eurymene)
dolabraria, and perhaps belongs to the same subgenus. It is found
in Massachusetts as well as on the northern shore of Lake Superior.

The antennae are brown, and are pectinated only in the males.
The tongue is half as long as the body, which, with the upper side
of the forewings, is citron-yellow ; the hindwings and under sides
are somewhat paler. The forewings have a rust-brown costal spot
near the shoulders, a transverse row of spots near the base, a stig-
matical dot, three little spots near the tip, and a very large lozenge-
shaped spot at the anal angle, of the same brown color, the large
spot being bordered before and behind with darker brown. The
hindwings have a central brownish dot, and a large pale brown spot,
bordered before and behind with a darker line at the anal angle,
which also is deeply tinged with brown.

THE ERRATIC PHENOMENA ABOUT LAKE SUPERIOR.

So much has been said and written within the last fifteen years,
upon the dispersion of erratic boulders and drift, both in Europe
and America, that I should not venture to introduce this subject
again, if I were not conscious of having essential additions to present
to those interested in the investigation of these subjects.

It will be remarked by all who have followed the discussions re-
specting the transportation of loose materials over great distances
from the spot where they occurred primitively, that the most minute
and the most careful investigations have been made by those geolo-
gists who have attempted to establish a new theory of their transpor-
tation by the agency of ice.

The part of those who claim currents as the cause of this trans-
portation has been more generally negative, inasmuch as, satisfied
with their views, they have generally been contented simply to deny
the new theory and its consequences, rather .than investigate anew
the field upon which they had founded their opinions. Without
being taxed with partiality, I may, at the outset, insist upon this
difference in the part taken by the two contending parties. For
since the publication of Sefstroem's paper upon the drift of Sweden,
in which very valuable information is given respecting the phenome-
na observed in that peninsula, and the additional data furnished by
de Verneuil and Murchison upon the same country and the plains of
Russia, the classical ground for erratic phenomena has been left
almost untouched by all except the advocates of the glacial theory.
I need only refer to the investigations of M. de Charpentier, Escher,
Von Derlinth and Studer, and more particularly to those extensive
and most minute researches of Prof. Guyot in Switzerland, with-

396 LAKE SUPERIOR.

out speaking of my own and some contributions from visitors, as
the Martins, James Forbes and others, to justify my assertion that
no important fact respecting the loose materials spread all over
Switzerland has been added by the advocates of currents since the
days of Saussure, DeLiic, Escher and Von Buch ; whilst Prof.
Guyot has most conclusively shown that the different erratic basins
in Switzerland are not only distinct from each other, as was already
known before, but that in each the loose materials are arranged
in well-determined regular order, showing precise relations to the
centres of distribution, from which these materials originated ; an
arrangement which agrees in every particular with the arrangement
of loose fragments upon the surface of any glacier, but which no
cause acting convulsively could have produced.*

The results of these investigations are plainly that the boulders
found at a distance from the central Alps, originated from their
higher summits and valleys, and were carried down at different suc-
cessive periods in a regular manner, forming uninterrupted walls and
ridges, which can be traced from their starting point to their
extreme peripheric distribution.

I have myself shown that there are such centres of distribution in
Scotland and England and Ireland. And these facts have been
since traced in detail in various parts of the British Islands by Dr.
Buckland, Sir Ch. Lyell, Mr. Darwin, Mr. McLachlan and Profes-
sor James D. Forbes, pointing clearly to the main mountain groups
as to so many distinct centres of dispersion of these loose materials.

Similar phenomena have been shown in the Pyrenees, in the
Black Forest, and in the Vosges, showing beyond question, that
whatever might have been the cause of the dispersion of erratic
boulders, there are several separate centres of their distribution to
be distinguished in Europe. But there is another question connect-
ed with this local distribution of boulders which requires particular
investigation, the confusion of which with the former has no doubt

*A comparison of the maps showing the arrangement of the moraines upon the
glacier of the Aar in my Systeme Glaciaire, with the map which Prof. Guyot is about to
publish of the distribution of the erratic boulders in Switzerland, will show more fully
the identity of the two phenomena.

THE ERRATIC PHENOMENA. 397

greatly contributed to retard our real progress in understanding the
general question of the distribution of erratics.

It is well known that Northern Europe is strewed with boulders,
extending over European Russia, Poland, Northern Germany, Hol-
land and Belgium. The origin of these boulders is far north in Nor-
way, Sweden, Lapland and Liefland, but they are now diffused over
the extensive plains west of the Ural Mountains. Their arrange-
ment, however, is such that they cannot be referred to one single
point of origin, but only in a general way to the northern tracts of
land which rise above the level of the sea in the Arctic regions.
Whether these boulders were transported by the same agency as
those arising from distinct centres, on the main continent of Europe,
has been the chief point of discussion. For my own part, I have
indeed no doubt that the extreme consequences to which we are
naturally carried by admitting that ice was also the agent in trans-
porting the northern erratics to their present positions, has been the
chief objection to the view that the Alpine boulders have been
distributed by glaciers.

It seemed easier to account for the distribution of the northern
erratics by currents, and this view appearing satisfactory to those
who supported it, they at once went further, and opposed the glacial
theory even in those districts where the glaciers seemed to give a
more natural and more satisfactory explanation of th phenomena.
To embrace the whole question it should be ascertained.

First, Whether the northern erratics were transported at the
same time as the local Alpine boulders, and if not, which of the
phenomena preceded the other ; and again, if the same cause
acted in both cases, or if one of the causes can be applied to one
series of these phenomena, and the other cause to the other series.
An investigation of the erratic phenomena in North America seems
to me likely to settle this question, as the northern erratics occur
here in an undisturbed continuation over tracrs < f land far more
extensive than those in which they have been observed in Europe.
For my own part, I have already traced them from the eastern
shores of Nova Scotia, through New England and the North West*
ern States of North America and the Canadas as far as the western
extremity of Lake Superior, a region embracing about thirty de-

398 LAKE SUPERIOR.

grees of longitude. Here, as in Northern Europe, the boulders
evidently originated farther north than their present location, and
have been moved universally in a main direction from north to
south.

From data which are, however, rather incomplete, it can be
further admitted that similar phenomena occur further west across
the whole continent, everywhere presenting the same relations.
That is to say, everywhere pointing to the north as to the region of
the boulders, which generally disappear about latitude 38°.

Without entering at present into a full discussion of any theoreti-
cal views of the subject, it is plain that any theory, to be satisfactory,
should embrace both the extensive northern phenomena in Europe
and North America, and settle the relation of these phenomena to
the well-authenticated local phenomena of Central Europe.

Whether America itself has its special local circumscribed cen-
tres of distribution or not, remains to be seen. It seems, however,
from a few facts observed in the White Mountains, that this chain,
as well as the mountains of north-eastern New York, have not been
exclusively — and for the whole duration -of the transportation of
these materials — under the influence of the cause which has distrib-
uted the erratics through such wide space over the continent of
North America. But whether this be the case or not, (and I
trust local investigations will soon settle the question,) I maintain
that the cause which has transported these boulders in the American
continent must have acted simultaneously over the whole ground
•which these boulders cover, as they present throughout the continent
an uninterrupted sheet of loose materials, of the same general
nature, connected in the same general manner, and evidently dis-
persed at the same time.

Moreover, there is no ground, at present, to doubt the simulta-
neous dispersion of the erratics over Northern Europe and Northern
America. So that the cause which transported them, whatever it
may be, must have acted simultaneously over the whole tract of land
west of the Ural Mountains, and east of the Rocky Mountains, with-
out assuming anything respecting Northern Asia, which has not yet
been studied in this respect ; that is to say, at the same time, over
a space embracing two hundred degrees of longitude.

THE ERRATIC PHENOMENA. 399

Again, the action of this cause must have been such, and I insist
strongly upon this point, as a fundamental one, the momentum with
which it acted must have been such, that after being set in motion
in the north, with a power sufficient to carry the large boulders
which are found everywhere over this vast extent of land, it vanished
or was stopped after reaching the thirty-fifth degree of northern
latitude.

Now it is my deliberate opinion that natural philosophy and math-
ematics may settle the question, whether a body of water of sufficient
extent to produce such phenomena can be set in motion with sufficient
velocity to move all these boulders, and nevertheless stop before hav-
ing swept over the whole surface of the globe. Hydrographers are
familiar with the action of currents, with their speed, and with the
power with which they can act. They know also how they are distrib-
uted over our globe. And, if we institute a comparison, it will be seen
that there is nowhere a current running from the poles towards the
lower latitudes, either in the northern or southern hemisphere, cover-
ing a space equal to one-tenth of the currents which should have
existed to carry the erratics into their present position. The widest
current is west of the Pacific, which runs parallel to the equator,
across the whole extent of that sea from east to west, and the great-
est width of which is scarcely fifty degrees. This current, as a
matter of course, establishes a regular rotation between the waters
flowing from the polar regions towards lower latitudes.

The Gulf Stream on the contrary runs from west to east, and dies
out towards Europe and Africa, and is compensated by the currents
from Baffin's Bay and Spitzbergen emptying into the Atlantic, while
the current of the Pacific, moving towards Asia and carrying floods
of water in that direction, is maintained chiefly by antarctic currents,
and those which follow the western shore of America from Behring's
Straits. Wherever they are limited by continents, we see that
the waters of these currents, even when they extend over hundreds of
degrees of latitude, as the Gulf Stream does in its whole course, are
deflected where they cannot follow a straight course.

Now without appealing with more detail to the mechanical con-
ditions involved in this inquiry, I ask every unprejudiced mind
acquainted with the distribution of the northern boulders, whether

400 LAKE SUPERIOR.

there was any geographical limitation to the supposed northern
current to cause it to leave the northern erratics of Europe in such
regular order, with a constant bearing from north to south, and to
form, on its southern termination, a wide, regular zone from Asia to
the western shores of Europe, north of the fiftieth degree of lati-
tude, before it had reached the great barrier of the Alps? I ask
whether there was such a barrier in the unlimited plains which
stretch from the Arctic seas uninterrupted over the whole northern
continent of America as far down as the Gulf of Mexico ?

I ask, again, why the erratics are circumscribed within the north-
ern limits of the temperate zone, if their transportation is owing to
the action of water currents ? Does not, on the contrary, this most
surprising limit within the artic and northern temperate zones, and
in the same manner within the antarctic and southern temperate
zones, distinctly show that the cause of transportation is connected
with the temperature or climate of the countries over which the
phenomena were produced. If it were otherwise, why are there no
systems of erratics with an east and west bearing, or in the main di-
rection of the most extensive currents flowing at present over the
surface of our globe ?

It is a matter of fact, of undeniable fact, for which the theory
has to account, that in the two hemispheres the erratics have direct
reference to the polar regions, and are circumscribed within the
arctics and the colder part of the temperate zone. This fact is as
plain as the other fact, that the local distribution of boulders has
reference to high mountain ranges, to groups of land raised above
the level of the sea into heights, the temperature of which is lower
than the surrounding plains. And what is still more astonishing,
the extent of the local boulders, from their centre of distribution,
reaches levels, the mean annual temperature of which corresponds
in a surprising manner with the mean annual temperature of the
southern limit of the northern erratics.

We have, therefore, in this agreement a strong evidence in favor
of the view that both the phenomena of local mountain erratics in
Europe and of northern erratics in Europe and America have
probably been produced by the same cause.

The chief difficulty is in conceiving the possibility of the formation of

THE ERRATIC PHENOMENA. 401

a sheet of ice sufficiently large to carry the northern erratics into their
present limits of distribution ; but this difficulty is greatly removed
when we can trace, as in the Alps, the progress of the boulders
under the same aspect from the glaciers now existing, down into
regions where they no longer exist, but where the boulders and other
phenomena attending their transportation show distinctly that they
once existed.

Without extending further this argumentation, I would call the
attention of the unprejudiced observer to the fact, that those who
advocate currents as the cause of the transportation of erratics, have,
up to this day, failed to show, in a single instance, that currents can
produce all the different phenomena connected with the transporta-
tion of the boulders which are observed everywhere in the Alps, and
which are still daily produced there by the small glaciers yet in
existence. Never do we find that water leaves the boulders which it
carries along in regular walls of mixed materials ; nor do currents
anywhere produce upon the hard rocks in situ the peculiar grooves
and scratches which we see everywhere under the glacier and within
the limits of their ordinary oscillations.

Water may polish the rocks, but it nowhere leaves straight
scratches upon their surface ; it may furrow them, but these furrows
are sinuous, acting more powerfully upon the soft parts of the rocks
or fissures already existing ; whilst glaciers smooth and level uni-
formly, the hardest parts equally with the softest, and, like a hard
file, rub to uniform continuous surfaces the rocks upon which they
move.

But now let us return to our special subject, the erratics of North
America.

The phenomena of drift are more complicated about Lake Supe-
rior than I have seen them anywhere else ; for, besides the general
phenomena which occur everywhere, there are some peculiarities
noticed which are to be ascribed to the lake as such, and which we
do not find in places where no large sheet of water has been brought
into contact with the erratic phenomena. In the first place, we
notice about Lake Superior an extensive tract of polished, grooved
and scratched rocks, which present here the same uniform character
which they have everywhere. As there is so little disposition, among

27

402 LAKE SUPERIOR.

so many otherwise intelligent geologists, to perceive the facts as they
are, whenever they bear upon the question of drift, I cannot but
repeat, what I have already mentioned more than once, but what I
have observed again here over a tract of some fifteen hundred
miles, that the rocks are everywhere smoothed, rounded, grooved
and furrowed in a uniform direction. The heterogeneous materials
of which the rocks consist are cut to one continuous uniform level,
showing plainly that no difference in the polish and abrasion can be
attributed to the greater or less resistance on the part of the rocks,
but that a continuous rasp cut down everything, adapting itself, how-
ever, to the general undulations of the country, but nevertheless
showing, in this close adaptation, a most remarkable continuity in
its action.

That the power which produced these phenomena moved in the
main from north to south, is distinctly shown by the form of the hills,
which present abrupt slopes, rough and sharp corners towards the
south, while they are all smoothed off towards the north.

Indeed, here, as in Norway and Sweden, there is on all the hills a
lee-side and a strike-side. As has been observed in Norway and
Sweden, the polishing is very perfect in many places, sometimes
strictly as brilliant as a polished metallic surface, and everywhere
these surfaces are more or less scratched and furrowed, and both
scratches and furrows are rectilinear, crossing each other under
various angles : however, never varying many points of the compass
on the same spot, but in general showing that where there are
deviations from the most prominent direction, they are influenced by
the undulations of the soil. It has been said, that the main direction
of these strise was from north-west to south-east, but I have found it
as often strictly from north to south, or even from north-east to
south-west ; and if we are to express a general result, we should say
that the direction, assigned by all our observations to the various
scratches, tends to show that they have been formed under the influ-
ence of a movement from north to south, varying more or less to the
east and west, according to local influences in the undulations of the
soil. It is, indeed, a very important fact, that scratches which seem
to have been produced at no great intervals from each other, are not
absolutely parallel, but may diverge for ten, fifteen, or more degrees.

THE ERRATIC PHENOMENA. 403

There is one feature in these phenomena, however, in which we
never observe any variation. The continuity of these lines is abso-
lutely the same everywhere. They are rectilinear and continuous,
and cannot be better compared than with the effects of stones or
other hard materials dragged in the same direction upon flat or roll-
ing surfaces ; they form simple scratches extending for yards in
straight lines, or breaking oif for a short space to continue again in a
straight line in the same direction, just as if interrupted by a jerk.
There are also deeper scratches of the same kind, presenting the
same phenomena, only, perhaps, traceable for a greater distance
than the finer ones. These scratches, instead of appearing like the
tracing of diamonds upon glass, as the former do, would rather assume
the appearance of a deeper groove, made by the point of a graver, or
perhaps still more closely resemble the scratches which a cart-wheel
would produce upon polished marble, if the wheel were chained, and
coarse sand spread over the floor. The appearance of the rock,
crushed by the moving mass, is especially distinct in limestone rocks,
where grooves are seldom nicely cut, but present the appearance of
a violent pressure combined with the grooving power, thus giving to
the groove a character which is quite peculiar, and which at once
strikes an observer who has been familiar with its characteristic
aspect. Now, I do not know upon what the assertions of some
geologists rest, that gravel moved by water under strong heavy
currents will produce similar eifects. Wherever I have gone since
studying these phenomena, I have looked for such cases, and have
never yet found modern gravel currents produce anything more than
a smooth surface with undulating furrows following the cracks in the
rocks, or hollowing their softer parts ; but continuous straight lines,
especially such crushed lines and straight furrows, I have never
seen.

When we know how extensive the action of water carrying mud
and gravel is on every shore and in every water current, — when we
can trace this action almost everywhere, and nowhere find it similar
to the phenomena just described, I cannot imagine upon what ground
these phenomena are still attributed to the agency of currents. This
is the less rational as we have at present, in all high mountain chains
of the temperate zone, other agents, the glaciers, producing these

404 LAKE SUPERIOR.

very same phenomena, with precisely. the same characters, to which,
therefore, a sound philosophy should ascribe, at least conditionally,
the northern and Alpine polished surfaces, and scratched and grooved
rocks, or at least acknowledge that the effect produced by the ac-
tion of glaciers more nearly resembles these erratic phenomena than
does that which results from the action of currents. But such is the
prejudice of many geologists, that those keen faculties of distinction
and generalization, that power of superior perception and discrimina-
tion which have led them to make such brilliant discoveries in geology
in general, seem to abandon them at once as soon as they look at the
erratics. The objection made by a venerable geologist, that the cold
required to form and preserve such glaciers, for any length of time,
would freeze him to death, is as childish as the apprehension that the
heavy ocean currents, the action of which he sees everywhere, might
have swept him away.*

Now that these phenomena have been observed extensively, we
may derive also some instruction from the limits of their geographi-
cal extent. Let us see, therefore, where these polished, scratched
and furrowed rocks have been observed.

In the first place they occur everywhere in the north within cer-
tain limits of the arctics, and through the colder parts of the tem-
perate zone. They occur also in the southern hemisphere, within
parallel limits, but ' in the plains of the tropics, and even in the
warmer parts of the temperate zone we find no trace of these phe-
nomena, and nevertheless the action of currents could not be less
there, and could not at any time have been less there than in the
colder climates. It is true, similar phenomena occur in Central
Europe and have been noticed in Central Asia, and even in the
Andes of South America, but these always in higher regions, at
definite levels above the surface of the sea, everywhere indicating a
connection between their extent and the colder temperature of the
places over which they are traced.

More recently, a step towards the views I entertain of this subject,
has been made by those geologists who would ascribe them to the
agency of icebergs. Here, as in my glacial theory, ice is made

* Berlin Academy, 1846.

THE ERKATIC PHENOMENA. 405

the agent ; floating ice is supposed to have ground and polished the
surfaces of rocks, while I consider, them to have been acted upon by
terrestrial glaciers. To settle this difference we have a test which is
as irresistible as the other arguments already introduced.

Let us investigate the mode of action, the mode of transportation
of icebergs, and let us examine whether this cause is adequate to
produce phenomena for which it is made to account. As mentioned
above, the polished surfaces are continuous over hills, and in depres-
sions of the soil, and the scratches which run over such undulating

7 o

surfaces are nevertheless continuous in straight lines. If we imagine
icebergs moving upon shoals, no doubt they would scratch and
polish the rocks in a way similar to moving glaciers. But upon such
grounds they would sooner or later be stranded, and if they remain-
ed loose enough to move, they would, in their gyratory movements,
produce curved lines, and mark the spots where they had been
stranded with particular indications of their prolonged action. But
nowhere upon arctic ground do we find such indications. Every-
where the polished and scratched surfaces are continuous in straight
juxtaposition.

Phenomena analogous to those produced by icebergs would only
be seen along the sea-shores ; and if the theory of drifted icebergs
were correct, we should have, all over those continents where erratic
phenomena occur, indications of retreating shores as far as the erratic
phenomena are found. But there is no such thing to be observed
over the whole extent of the North American continent, nor over
Northern Europe and Asia, as far as the northern erratics extend.
From the arctics to the southernmost limit of the erratic distribu-
tion, we find nowhere the indications of the action of the sea as
directly connected with the production of the erratic phenomena.
And wherever the marine deposits rest upon the polished surfaces
of ground and scratched rocks, they can be shown to be deposits
formed since the grooving and polishing of the rocks, in consequence
of the subsidence of those tracts of land upon which such deposits
occur.

Again, if we take for a moment into consideration the immense
extent of land covered by erratic phenomena, and view them as
produced by drifted icebergs, we must acknowledge that the ice-

bergs of the present period at least, are insufficient to account
for them, as they are limited to a narrower zone. And to bring
icebergs in any way within the extent which would answer for
the extent of the distribution of erratics, we must assume that
the northern ice fields, from which these icebergs could be detach-
ed and float southwards, were much larger at the time they pro-
duced such extensive phenomena than they are now. That is to
say, we must assume an ice period ; and if we look into the circum-
stances we shall find that this ice period, to answer to the phenome-
na, should be nothing less than an extensive cap 'of ice upon both
poles This is the very theory which I advocate ; and unless the
advocates of an iceberg theory go to that length in their premises, I
venture to say, without fear of contradiction, that they will find the
source of their icebergs fall short of the requisite conditions which
they must assume, upon due consideration, to account for the whole
phenomena as they have really been observed.

But without discussing any farther the theoretical views of the
question, let me describe more minutely the facts as observed on the
northern shores of Lake Superior. The polished surfaces, as such,
are even, undulating, and terminate always above the rough lee-side
turned to the south, unless upon gentle declivities, where the polish-
ed surfaces extend in unbroken continuity upon the southern surfaces
of the hills, as well as upon their northern slopes. On their eastern
and western flanks, shallow valleys running east and west are as
uniformly polished as those which run north and south ; and this fact
is more and more evident, wherever scratches and furrows are also
well preserved and distinctly seen, and by their bearings we can
ascertain most minutely, the direction of the onward movement which

produced the whole phenomena. Nothing is more striking in this
respect than the valleys or depressions of the soil running east and
west, where we see the scratches crossing such undulations at right
angles, descending along the southern gentle slope of a hill, travers-
ing the flat bottom below, and rising again up the next hill south, in
unbroken continuity. Examples of the kind can be seen everywhere
in those narrow inlets, with shallow waters intersecting the innumera-
ble highlands along the northern shores of Lake Superior, where the
scratches and furrows can be traced under water from one shore to

THE ERRATIC PHENOMENA. 407

the other, and where they at times ascend steep hills, which they
cross at right angles along their northern slope, even when the
southern slope, not steeper in itself, faces the south with rough
escarpments.

The scratches and furrows, though generally running north and
south, and deviating slightly to the east and west, present in various
places remarkable anomalies, even in their general course along the
eastern shore of the lake. Between Michipicotin and Sault St.
Marie we more frequently see a deflection to the west than a due
north and south course, which is rather normal along the northern
shore proper, between Michipicotin and other islands, and from the
Pic to Fort William ; the deep depression of the lake being no doubt
the cause of such a deviation, as large masses of ice could accumu-
late in this extensive hollow cavity before spreading again more uni-
formly beyond its limits. To the oscillations of the whole mass in its
southerly movement, according to the inequalities of the surfaces,
we must ascribe the crossing of the straight lines at acute angles, as we
observe also at the present day under the glaciers, as they swell and
subside, and hence meet with higher and lower obstacles in their
irregular course between the Alpine valleys.

In deep, narrow chasms, however, we find now and then greater
deviations from the normal direction of the strige, where considerable
masses of ice could accumulate, and move between steep walls under a
lateral pressure of the masses moving onwards from the north. Such a
chasm is seen between Spar Island and the main land opposite Prince's
Location, south of Fort William, where the furrows and scratches run
nearly east and west. But here also, there is no tumultuous disturb-
ance in the continuation of the phenomena, such as would occur if ice-
bergs were floated and stranded against the southern barrier. The
same continuity of even, polished surfaces, with their scratches and
furrows, prevails here as elsewhere. The angles which these scratches
form with each other are very acute, generally not exceeding 10° ;
but at times they diverge more, forming angles of 15°, 20° and 25°.
In a few instances, I have even found localities where they crossed
each other at angles of no less than 30° ; but these are rare excep-
tions. It may sometimes be noticed that the lines running in one
direction form a system by themselves, varying very little from strict

408 LAKE SUPERIOR.

parallelism with each other, but crossing another system, more or less
strongly marked, of other lines equally parallel with each other. At
other times, a system of lines, strongly marked and diverging very
slightly, seem to pass over another system, in which the lines form
various angles with each other. Again, there are places, — and this
is the most common case, — where the lines diverge slightly, following,
however, generally one main direction, which is crossed by fewer
lines, forming more open angles. These diiferences, no doubt, indi-
cate various oscillations m the movement of the mass which produced
the lines, and show probably its successive action, with more or less
i itensity, upon the same point at successive periods, in accordance
with the direction of the moving force at each interval. The same
variations within precisely the same limits may be noticed in our day
on the margin of the glaciers produced by the increase or diminution
of the bulk of their mass, and the changes in the rate of their move-
ment.

The loose materials which produced, in their onward movement
tinder the pressure f ce, such polishing and grooving, consisted of
various sized boulders, pebbles and gravels, down to the most minute
sand and loamy powder. Accumulations of such materials are found
everywhere upon these smooth surfaces, and in their arrangement
they present everywhere the most striking contrast when compared
with deposits accumulated under the agency of water. Indeed, we
nowhere find this glacial drift regularly stratified, being everywhere
irregular accumulations of loose materials, scattered at random with-
out selection, the coarsest and most minute particles being piled
irregularly in larger or smaller heaps, the greatest boulders standing
sometimes uppermost, or in ths centre, or in any position among
smaller pebbles and impalpable powder.

And these materials themselves are scratched, polished and fur-
rowed, and the scratches and furrows are rectilinear as upon the
rocks in situ underneath, not bruised simply, as the loose materials
carried onward by currents or driven against the shores by the tides,
but regularly scratched, as fragments of hard materials would be if
they had been fastened during their friction against each other, just
as we observe them upon the lower surface of glaciers where all the
loose materials set in ice, as stones in their setting, are pressed and

THE ERRATIC PHENOMENA. 409

rubbed against underlying rocks. But the setting here being simply
ice, these loose materials, fast at one time and movable another, and
fixed and loosened again, have rubbed against the rock below in all
possible positions ; and hence not only their rounded form, but also
their rectilinear grooving. How such grooves could be produced
under the action of currents, I leave to the advocates of such a
theory to show, as soon as they shall be prepared for it.

I should not omit here to mention a fact which, in my opinion, has
a great theoretical importance, namely, that in the northern erratics,
even the largest boulders, as far as I know, are rounded, and
scratched and polished, at least, all those which are found beyond
the immediate vicinity of the higher mountain ranges ; showing that
the accumulations of ice which moved the northern erratics covered
the whole country ; and this view is sustained by another set of facts
equally important, namely, that the highest ridges, the highest
rugged mountains, at least, in this continent and north of the Alps in
Europe, are as completely polished and smoothed as the lower lands,
and only a very few peaks seem to have risen above the sheet of ice ;
whilst, in the Alps, the summits of the mountains stand generally
above these accumulations of ice, and have supplied the surface of
the glaciers with large numbers of angular boulders, which have been
carried upon the back of glaciers to the lower valleys and adjacent
plains without losing their angular forms.

With respect to the irregular accumulation of drift-materials in the
north, I may add that there is not only no indication of stratification
among them, such unquestionably as water would have left, but
that the very nature of these materials shows plainly that they are of
terrestrial origin ; for the mud which sticks between them adheres to
all the little roughnesses of the pebbles, fills them out, and has the
peculiar adhesive character of the mud ground under the glaciers,
and differing entirely in that respect from the gravels and pebbles
and sands washed by water currents, which leave each pebble
clean, and never form adhering masses, unless penetrated by an
infiltration of limestone.

Another important fact respecting this glacial drift consists in
the universal absence of marine as well as freshwater fossils in its
interior, a fact which strengthens the view that they have been

410

LAKE SUPERIOR.

accumulated by the agency of strictly terrestrial glaciers ; such is,
at least, the case everywhere far from the sea-shore. But we may
conclude that these ancient glaciers reached, upon various points, the
sea-shore at the time of their greatest extension, just as they do at
present in Spitzbergen and other arctic shores ; and that therefore,
in such proximity, phenomena of contact should be observed, indi-
cating the onward movement of glacial material into the ocean, such
as the accumulation within these materials of marine fossil remains,
and also the influence of the tidal movements upon them. And now
such is really the case. Nearer the sea-shores we observe distinctly,
in some accumulations of the drift, faint indications of the action of
the tide reaching the lower surface of glaciers, and the remodeling,
to some extent, of the materials which there poured into the sea. A
beautiful example of the kind may be observed near Cambridge,
along Charles River, not far from Mount Auburn, where the unstrati-

fied glacial drift («) presents in its upper masses strictly the charac-
ters of true terrestrial glacial accumulation, but shows underneath
faint indications (5) of the action of tides. Above, regular tidal
strata (c) are observed, formed probably after the masses below had
subsided. The surface of this accumulation is covered with soil (c£).
The period at which these phenomena took place cannot be fully
determined, nor is it easy to ascertain whether all glacial drift is
contemporaneous. It would seem, however, as if the extensive accu-
mulation of drift all around the northern pole in Europe, Asia and
America was of the same age as the erratics of the Alps. The cli-
matic circumstances capable of accumulating such large masses of

THE ERRATIC PHENOMENA. 411

ice around the north pole, having, no doubt, extended their influence
over the temperate zone, and probably produced, in high mountain
chains, as the Alps, the Pyrenees, the Black Forest, and the Vosges,
such accumulations of snow and ice, as may have produced the erratic
phenomena of those districts. But extensive changes must have
taken place in the appearance of the continents over which we trace
erratic phenomena, since we observe in the Old World, as well as in
North America, extensive stratified deposits containing fossils which
rest upon the erratics ; and as we have all possible good reasons and
satisfactory evidence for admitting that the erratics were transported
by the agency of terrestrial glaciers, and that therefore the tracts of
land over which they occur, stood at that time above the level of the
sea, we are led to the conclusion that these continents have subsided
since that period below the level of the sea, and that over their
inundated portions animal life has spread, remains of organized beings
have been accumulated, which are now found in a fossil state in the
deposits formed under those sheets of water.

Such deposits occur at various levels in different parts of North
America. They have been noticed about Montreal, on the shores of
Lake Champlain, in Maine and also in Sweden and Russia ; and,
what is most important, they are not everywhere at the same absolute
level above the surface of the ocean, showing that both the subsidence,
and the subsequent upheaval which has again brought them above
the level of the sea, have been unequal ; and that we should there-
fore be very cautious in our inferences respecting both the continental
circumstances under which the ancient glaciers were formed, and also
the extent of the sea afterward, as compared with its present limits.

The contrast between the unstratih'ed drift and the subsequently
stratified deposits is so great, that they rest everywhere unconform-
ably upon each other, showing distinctly the difference of the agency
under which they were accumulated. This unconformable superposi-
tion of marine drift upon glacial drift is also beautifully shown at the
above mentioned locality near Cambridge. (See Diagram.) In this
case the action of tides in the accumulation of the stratified materials
is plainly seen,

The various heights at which these stratified deposits occur, above
the level of the sea, show plainly, that since their accumulation, the

412 LAKE SUPERIOR.

main land has been lifted above the ocean at different rates in differ-
ent parts of the country ; and it would be a most important investi-
gation to have their absolute level, in order more fully to ascertain
the last changes which our continents have undergone.

From the above mentioned facts, it must be at once obvious that
the various kinds of loose materials, all over the northern hemisphere,
have been accumulated, not only under different circumstances, but
during long-continued subsequent distinct periods, and that great
changes have taken place since their deposition, before the present
state of things was fully established.

To the first period, — the ice period, as I have called it, — belong
all the phenomena connected with the transportation of erratic bould-
ers, the polishing, scratching and furrowing of the rocks and the
accumulation of unstratified, scratched, and loamy drift. During that
period, the main land seems to have been, to some extent at least,
higher above the level of the sea than now ; as we observe, on the
shores of Great Britain, Norway and Sweden, as well as on the east-
ern shores of North America, the polished surfaces dipping under
the level of the ocean, which encroaches everywhere upon the erratics
proper, effaces the polished surfaces and remodels the glacial drift.
During these periods, large terrestrial animals lived upon both conti-
nents, the fossil remains of which are found in the drift of Siberia,
as well as of this continent. A fossil elephant recently discovered in
Vermont adds to the resemblance, already pointed out, between the
northern drift of Europe and that of North America ; for fossils of
that genus are now known to occur upon the northernmost .point of
the western extremity of North America, in New England, in North-
ern Europe, as well as all over Siberia.

To the second period we would refer the stratified deposits resting
upon drift, which indicate that during their deposition the northern
continent had again extensively subsided under the surface of the
ocean.

During this period, animals, identical with those which occur in
the northern seas, spread widely over parts of the globe which are
now again above the level of the ocean. But, as this last elevation
seems to have been gradual, and is even still going on in our day,
there is no possibility of tracing more precisely, at least for the

THE ERRATIC PHENOMENA. 413

present, the limit between that epoch and the present state of things.
Their continuity seems almost demonstrated by the identity of fossil
shells found in these stratified deposits, with those now living along
the present shores of the same continent, and by the fact that changes
in the relative level between sea and main land are still going on in
our day.

Indications of such relative changes between the level of the
•waters and the land are also observed about Lake Superior. And
here they assume a very peculiar character, as the level of the lake
itself, in its relation to its shores, is extensively changed.

All around Lake Superior we observe terraces at different levels ;
and these terraces vary in height, from a few feet above the present
level of the lake, to several hundred feet above its surface, presenting
everywhere undoubted evidence, that they were formed by the
waters of the lake itself.

As everywhere the lake shores are strewed with sand and pebbles
stranded within certain limits by the waves, the lowest accumulations
of loose materials remain within the action of heavy storms, and
within such limit they are entirely deprived of vegetation.

Next, another set of beaches is observed, consisting generally of
coarser materials, forming shelves above the reach of even the severest
storms, as shown by the scanty cryptogamous vegetation, and a few
small herbaceous plants which have grown upon them.

Next, other beaches, retreating more and more from the shores,
are observed, upon which an older vegetation is traced, consisting of
shrubs, small trees, and a larger number of different plants, among
which extensive carpets of wonderful lichens sometimes spread over
large surfaces of greater extent. And the gentle slope of some of
the terraces shows that the lake must have stood at this level for a
longer time, as higher banks rise precipitously above them, consisting
also of loose materials, which must have been worn out and washed
away, for a considerable time, by the action of the waves from the
lake. In such a manner, terrace above terrace may be observed,
in retreating sheltered bays or along protected shores, over exten-
sive tracts ; sometimes two or three in close proximity, perhaps
within twenty to fifty feet of each other ; and again, extensive flat
shores, spreading above to another abrupt bank, making the former

414 LAKE SUPERIOR.

shore, above which other and other terraces are seen ; six, ten, even
fifteen such terraces may be distinguished on one spot, forming, as it
were, the steps of a gigantic amphitheatre. The most remarkable of
all the amphitheatres has been sketched by Mr. Cabot, and forms the
frontispiece to this volume. Its height has been determined by Mr.
Logan, in his Geographical Report of Canada, page 10, where it is
minutely described. I therefore refer to this account for further de-
tails. I would only mention here, that the first shelf, within the reach
of the lake, consists of minute sand, and forms a narrow strip of sterile
ground along the water-edge ; next, we have a slope of about 10°, fol-
lowed by a flat terrace, extending for nearly fifty paces to a seconl
verv steep slope, about 26° and 30° inclination ; then, a sloping ter-
race with an inclination of near 16°, stretching for eighty to a hundred
paces, above which rises another steep slope of 20°, beyond which
an extensive flat, slightly sloping, extends for several hundred paces,
crowned by some irregular ridges at its summit, and along the rocky
ledges which form the bay at the bottom of which this high gravel
bank rises. .

In connection with these lake terraces, we must consider also the
river terraces which present similar phenomena along their banks all
around the lake, with the difference that they slope gradually along
the water courses, otherwise resembling in their composition the lake
terraces, which are altogether composed of remodeled glacial drift,
which, from the influence of the water and their having been rolled
on the shores, have lost, more or less, their scratches and polished ap-
pearance, and have assumed the dead smoothness of water pebbles.
Such terraces occur frequently between the islands, or cover low necks
connecting promontories with the main land, thus showing, on a small
scale, how by the accumulation of loose materials, isolated islands
may be combined to form larger ones, and how, in the course of time,
by the same process, islands may be connected with the main land.

The lake shores present another series of interesting phenomena,
especially near the mouth of larger rivers emptying into the lake
over flats, where parallel walls of loose materials, driven by the action
of the lake against the mouth of the river, have successively stopped
its course and caused it to wind its way between the repeated accu-
mulations of such obstacles.

THE ERRATIC PHENOMENA. 415

The lower course of Michipicotin River is for several miles dammed
up in that way by concentric walls, across which the river has cut
its bed, and winding between them, has repeatedly changed its direc-
tion, breaking through the successive walls in different places. The
largest and lowest of these walls, a kind of river terrace near the
margin of the lake, shuts at present the factory from the immediate
lake shore and the river, which has cut its way between the rocks to
the right and the walls, has left a bold bank in this dam on its left
shore.

An important question now arises, after considering these facts,
how these successive changes in the relative level of the lake and its
shores have been introduced. Has the water been gradually sub-
siding, or has the shore been repeatedly lifted up ? Merely from
the general inferences of the more extensive phenomena described
above, respecting the relative changes between land and sea, I
should be inclined to admit that the land has risen, rather than to
suppose that the waters have gradually flowed out. But there are
about the lake itself sufficient proofs, which leave in my mind not
the slightest doubt that it is the land which has changed its level,
and not the lake which has subsided.

In the first place, to suppose that the lake had once stood as high
as the highest terraces, it would be necessary to admit that its banks
were, all round its shores, sufficiently high to keep the water at that
highest level, or, at least, that there were, at the lower outlets, bars
to that height, which have been gradually removed since. But
neither is the main land sufficiently high, at the western extremity
and along the southern shores, to admit of such a supposition, nor is
there about the outlet of the lake, between Gros Cap and Cap Iro-
quois, an indication of a barrier which has been gradually removed.
There, as everywhere along the lake shores, the loose movable mate-
rials consist of the same drift, the accumulation of which, at various
levels, we are aiming to account for. If, therefore, we consider this
same drift as the barrier under whose protection the lake modeled
other parts of its mass, we should be compelled to admit another
cause to remove the barrier, a supposition for which there is not the
slightest indication in the geological structure of the country. But
if, on the contrary, we suppose the lake to have removed the barrier,

416 LAKE SUPERIOR.

there is no cause left for its accumulation, and the changes in the
comparative level of the main land and the terraces remain equally
unaccounted for.

Indeed, the terraces are so unequal in their absolute level when
compared to each other, that a gradual subsidence of the lake remov-
ing a barrier of loose materials at its outlet could never explain their
irregularity. But if we suppose that the innumerable dykes which
cross, in all directions, the rocks which form the shores of the lake,
have at various intervals lifted up these shores, we have at the same
time a cause for the change of the relative level between the terraces
and the lake, and also for the change of its absolute level, as it
removed larger and larger portions of materials accumulated at its
eastern extremity.

That these dykes have produced such changes will not be doubted
by any one who may study the phenomena described in the follow-
ing chapter respecting the origin of the present outlines of the lakes,
as produced by the intersection of all the dykes traversing the
metamorphic and plutonic rocks of the northern shores.

We should therefore conclude that, as there has been a general
gradual change between the relative level of the main land and sea,
so there has also been a gradual local change in the relative level of
the lake and its shores ; and hence the local phenomena would only
corroborate the induction derived from more general geological facts.

XI.

THE OUTLINES OF LAKE SUPERIOR.

SINCE it has been ascertained that the present form of the surface
of our globe, and the distribution of land and water and their rela-
tive level, and the general outline of their contact, is the result of
the successive geological changes which our globe has undergone,
the efforts of geologists have more or less had in view to ascertain
the order of succession of these phenomena, and their mutual depen-
dence. One result is already established beyond question, namely,
that the changes which have brought about the present physical
state of our globe have been successive and gradual, and have
followed each other at more or less remote epochs. So that its pres-
ent configuration, far from being the result of one creative act, must
be considered as the combination of a series of successive changes ;
fa from being moulded like a bell at one furnace, it has been built
up by successive superstructures. This is not merely a view adopted
in accordance with our theories and preferences, but it is actually
shown by geological evidence, that the solid parts which constitute
the crust of our globe have been consolidated at different epochs,
and have been lifted to the surface above the level of the sea at long
distant intervals ; so that continents are known to have been built
up by the successive rise of groups of islands, combining, by their
gradual elevation above the level of the sea, into larger tracts of
main land, until they have assumed their present definite outline and
general relations.

The modes in which these changes have taken place have been
quite diversified. We have indications of large tracts of land ex-
tending in horizontal continuity over great extents at considerable
heights above the level of the sea.

28

418 LAKE SUPERIOR.

We have in other instances, ridges of mountain chains intersecting
the plains and forming prominent walls in various directions across
the more level country. We have again isolated peaks rising like
pyramids above the surrounding country, — shallow waters covering
large flats, — deep excavations extending over considerable parts of
the ocean, — or narrow chasms, precipitous holes increasing the diver-
sity of the bottom of the sea, as mountain chains, volcanic cones,
high plateaus, deep valleys, rolling hills, and flat plains modify the
aspect of the main land. And all these differences, all these pecu-
liar features have been introduced gradually and successively by the
combined action of the elevation of the land, and recession of the
sea ; by the uplifting of the solid crust by volcanic and plu tonic
action, and by the abrading influence of water currents, and the
regular undulations of the ocean tides.

Taking the whole globe in its general appearance, we can thus
trace to the agency of a few influences, repeated at long intervals in
different ways, all the phenomena we observe upon its surface. And
the order of succession of the isolated events which have thus modi-
fied the surface of our globe has been ascertained with such unex-
pected precision, that at present, the relative age of the different
geological events is established with as much certainty as the great
periods in the history of mankind.

There is, however, one direction in which these investigations
need to be followed out still farther. The secondary events of
minor extent and less prominent importance have to be studied with
the same precision, and'perhaps with even more detail, than the
general phenomena have been, up to the present time. After work-
ing out the general history of our globe, we have, as it were, to
write its memoirs, the anecdotic part of the relation, and try to
contribute in this minute investigation to a fuller illustration of its
history. After ascertaining, in a general way, that the elevation of
mountain chains, the rise of extensive tracts of land, have marked
out the general outlines of continents and their limits with reference
to the ocean ; knowing, for instance, that the Scandinavian Alps de-
termine the general form of Norway and Sweden ; that Spain is
separated from France by a high mountain range ; that it owes its

OUTLINES OF LAKE SUPERIOR. 419

square form to the direction of its mountain chains precisely as Italy
derives its form from the direction of its mountains ; after having
satisfied ourselves that the existence of an almost unbroken chain of
the highest mountains, over the centre of Europe and Asia, consti-
tutes the main difference in the physical features of the Old World,
when contrasted with those of America, where the principal moun-
tains run north and south ; after having thus ascertained the inti-
mate relation there is in general, between geological phenomena and
the geography of continents, the physical features of the different
parts of the world, it is a subject worthy of our attention to investi-
gate how far the particular features we may distinguish in a given
circumscribed locality may be ascribed to similar agencies, and to
subordinate influences depending upon the same general principles,
which have been active in the production of the general frame.

Are the Swiss lakes, for instance, with their peculiar form, as
naturally the consecpuence of geological phenomena as the general
features of the country ? Are the numerous fiords of Norway
and Maine owing to the same cause ? Is there any connection
which can be appreciated with any degree of precision between the
general course of rivers on one continent, or in various parts of the
same continent ? And can a single lake, for instance Lake Superior,
be analyzed, so as to refer the bearings of its outlines to precise
geological phenomena ?

The knowledge I had before visiting Lake Superior, of the direct
connection of many of these apparently subordinate features in the
physical aspect of a country, with the main geological phenomena
upon which it rests, led me, during my excursions on this continent.
to keep this subject constantly in view. I had seen how the Lakes of
Neuchatel and Bienne were excavated at the junction of the Jura,
and the tertiary deposit at its base ; I had noticed that the Alpine
lakes followed fissures at right angles with the axis of elevation of
the Alps. I was aware that some of these lakes consist of two
distinct parts, probably formed at different periods, but now united by
the sheet of water filling them.

With such intimations, the great Canadian lakes, which form so
naturally a boundary between the Northern United States and the
British possessions upon this continent, could not but strongly call

420 LAKE SUPERIOR.

for an investigation of their natural features ; some running east and
west, others straight north and south, and others forming a regular
crescent, with its convexity turned northwards. Their absolute po-
sition is at once characteristic. They are excavated chiefly between
the plutonic masses rising north, and the stratified deposits south of
the primitive range.

Lake Superior, especially, fills a chasm between the northern
granitic and metamorphic range, and the oldest beds deposited
along their southern slopes in the primitive age of this continent.
Lake Ontario and Lake Erie, on the contrary, run between the suc-
cessive layers of different sets of beds of the same great geographical
period ; while Lakes Huron and Michigan fill up the cracks which
run at right angles with the main northern primitive range, and
which, no doubt, owe their origin to the elevation of the chains north
of Lake Huron and Lake Superior ; repeating, on a large scale,
what has been said above of the dependence of the Swiss lakes
upon their geological positions and relation to the mountain chains
which encircle them.

Besides this general relation of the lakes in connection with their
shores, I have been able to trace a more intimate connection of the
outlines of their shores and their geological structure, especially in
Lake Superior.

As a whole, that lake resembles a large crescent, with its convexity
turned northwards ; but it were a great mistake to imagine that this
form is actually the form of the shores, or that it is repeated upon
every point. On the contrary, the general outline of that lake is
the accidental result of the combination of many details, of many
geological events which have followed each other at different periods,
have modified the tract of land where the lake now exists, and have
cut up its foundation in such a manner as to break the continuity of
the solid rock, and allow it to be decomposed. Thus an extensive
crescent-shaped hole with innumerable islands has been formed, in
which the islands, in their various bearings, still indicate the direction
of the intersecting masses, and appear at present as the fragmentary
remains of a continuous tract of land, which is now replaced by a
deep lake.

For many weeks I had been tracing the dykes which intersect the

OUTLINES OF LAKE SUPERIOR. 421

»

shores of Lake Superior in almost all directions, when I was one day
most forcibly struck with the fact, that these dykes agree, in their
bearings, with the bearings of the shores ; and that even the greatest
complications in the outlines of the shores could be accounted for, by
the combinations of dykes intersecting each other in different direc-
tions. And indeed, now that I have the key for such an analysis,
I find no difficulty in referring, even short lines of the coast, to
the different systems of dykes which I know to exist there, and
wherever my memoranda are sufficiently full, I find indications of
dykes running in the direction of the coast. As soon as my attention
had been called to these phenomena, I lost no opportunity of invest-
igating the nature of the rock of these different systems of dykes,
and I ascertained, to my great astonishment, that there are consid-
erable differences in their mineralogical characters ; some being am-
phibolic trap ; others being injected with epidote ; others having
more the appearance of pitchstone ; and, what is particularly inter-
esting, the dykes which run in the same direction preserve the same
mineralogical character, as well as the same bearing.

The systems of dykes which run directly north and south, and
which form the inlets between Neepigou Bay and the main lake, and
intersect the large island of St. Ignace, and separate St. Ignace
stielf from the main land, all run north and south, and consist of
very hard, tough, unaltez-able hornblende trap, of a crystalline
aspect, and a grayish color ; while the dykes, which run east and
west, and mark out the northern and southern shores of those same
islands, consist mostly of a greenish trap extensively injected with
epidote, and breaking with the greatest ease into angular, irregular
fragments. The northern shore east of the Pic has the same general
bearing, due east and west ; and here, also, we find the dykes more
or less epidotic, and the metamorphic rocks talcose.

Again, the long shore running clue east and west from Michipico-
tin Avestwards, is, also, along its whole extent, intersected by epidotic
dykes running east and west.

The dykes of the north-eastern coast of the lake between the Pic
and Michipicotin Island, which run north north-east to south south-
west, consist of a pitchstone trap, like black glass, which, notwith-
standing its external hardness, readily decomposes, and forms almost

r

everywhere along these shores, coves, deep coves, narrow, straight
inlets, small caves, and gives to the whole extent of that shore that
peculiar aspect which distinguishes it so much from the other parts
of the lake.

The more precipitous shores — almost vertical walls, and those pe-
culiar modes of decomposition of the rocks which have left strange
appearances in the masses, some of which have even been noticed
by the Indian voyageurs, as Otter Head, for instance — the number-
less exceedingly small islands of these shores, and the striking bald*
ness of the overhanging rocks, are all of them most remarkable
features. Though these examples are very striking, and may at
once satisfy the mind that the most minute details in the peculiar
features of the lake may be ascribed to geological agency, we never-
theless find still more striking evidence of this connection between
the geological structure of the country and its form, along the north-
western shore, west of St. Ignace, and between Isle Royale and
Fort William. Three other systems of dykes here intersect the
rocks, and give to the whole shore an entirely different aspect. At
first sight, the bearings of the north-westerly shore appear already
different from those of the northern shore proper, and the eastern
shore, as their general course is north-east and south-west from the
southern extremity of St. Ignace to Pigeon Bay, to which Isle Roy-
ale is parallel. But upon a close examination of these shores, it
becomes obvious that this general feature is modified in various ways
by the lines of the shore intersecting each other at acute angles, in
three directions, and each of these different directions correspond
exactly to as many systems of independent dykes. The eastern and
western shores of Thunder Bay, or rather of the peninsula of Thun-
der Cape, run north-east, and parallel to them we have the cliffs of the
shores south of Fort William, and west of Pic Island, which present
the same bearings, as well as the shores of Black Bay also. The
dykes which run in that direction are narrow belts of black trap.
Nearly in the same direction, and very different in their mineralogi-
cal character, we find another set of dykes which run almost due
north-east and south-west. The direction of these dykes is best indi-
cated by a series of islands south of Sturgeon Bay, forming several
parallel ridges, one of which consists of a series of small islands

OUTLINES OP LAKE SUPERIOR. 423

known under the name of Victoria and Spar Islands, and the other
islands continuous with Sturgeon Island, in the prolongation of which
we meet the most prominent dykes of Pic Island itself. The whole
of Isle Royale lies in that direction, and the numerous promontories
of its eastern extremity are particularly remarkable for their agree-
ment, both in direction and geological structure, with the Victoria
group of islands. The system is particularly rich in copper ores, and
presents the most beautiful development of spathic veins. As I have
not myself examined Point Keewenaw, I cannot say how far the
prominent ridges there agree with those of Isle Royale and the Vic-
toria Islands ; but the agreement in the direction of the promon-
tory itself is most striking ; and the fact that this is the main centre
of copper injections suggests the probability that Point Keewenaw
also belongs, in its principal features, to this system ; and I should
not be in the least surprised if La Pointe and Whitefish Point de-
rive their main features from dykes of the same system, though
their solid foundation is concealed by accumulations of sand. The
third system in this north-eastern shore runs east north-east near east,
and is particularly marked along the southern shore of Thunder
Cape peninsula, along which the dykes are nearly east and west, as
just mentioned, deviating sufficiently to the north, however, to be
clearly distinct from the dykes which form the shores from the Pic to
St. Ignace, or from Michipicotin to Otter Head. And the nature of
the rock of these dykes differs widely from the last, there being no
epidotic injections accompanying them, and the trap being, on the
contrary, of a light grayish color, resembling more the system which
runs due north and south than any other.

So we have here six distinct systems of dykes, which contribute
mainly to the formation of the northern shore of Lake Superior.

1. System of Michipicotin, running east and west. (See the
annexed chart of the Outlines of Lake Superior.)

2. System of the Pic running north 30° west.

8. System of Neepigon, running due north and south.

4. System of Black Bay, running north 30° east.

5. System of Thunder Cape, running east 30° north.

6. System of Isle Royale, running east 45° north.

424 LAKE SUPERIOR.

The large group of islands on the southern and eastern side of
Black Bay, and south-west of St. Ignace, consists of innumerable
islets, separated from each other by the close intersection of the three
systems of dykes, which appear more prominent and strongly marked
in their features further west, in Isle Royale and Victoria Islands,
and about Thunder Bay.

But besides these six clearly defined systems, there seem to be
two more, or at least one other distinct system running due north-west
and south-east, cutting at right angles through Spar Island, and re-
appearing, as I understand from verbal communications of Mr. Foster,
further south upon Point Keewenaw. This system is perhaps the
cause of the bearing of the shores between Keewenaw Bay and Dead
River ; also of the outlet of Lake Superior between Point Iroquois
and Gros Cap along the river St. Mary, unless this eastern system
of intersection be distinct from the more western one.

But however this may be, so much is plain ; — that at least six
distinct systems of dykes, with peculiar characteristic trap, forming
parallel ridges in the same system, but varying, for different angles,
between the different systems, intersect the northern shores of Lake
Superior, and have probably cut up the whole tract of rock, over the
space which is now filled by the lake, in such a way as to destroy its
continuity ; to produce depressions, and to have gradually created an
excavation which now forms the lake, and thus to have given to it
its present outline. This process of intersection, these successive
injections of different materials, have evidently modified, at various
epochs, the relative level of the lake and land, and probably also
occasioned the modification which we notice in the deposition of the
shore drift, and the successive amphitheatric terraces which border, at
various heights, its shores.

A more minute analysis of the mineralogical character of these
dykes would no doubt afford satisfactory evidence of their original
independence, and perhaps lead, in connection with a fuller investi-
gation of their intersections, to the means of ascertaining their rela-
tive age. But I became fully aware of the geological importance
and independence of these different systems of dykes only during
my return, after leaving the neighborhood of Thunder Cape, the
ground where this part of the subject might be best studied, and

OUTLINES OP LAKE SUPERIOR. 425

therefore I can now only call the attention of geologists to these
facts, in the hope that they may, at some future time, be more fully
investigated.

The whole range of rocks which constitutes the northern shore of
Lake Superior is so extensively metamorphic, and so thoroughly in-
jected in all directions by veins intersecting each other, that it is no
easy task to analyze their relations ; and for a full illustration of this
subject, minute maps of well-selected localities are required, such as
travelling geologists on an occasional visit can scarcely prepare. But
I should be perfectly satisfied to see these hints more completely
wrought by others, satisfied, as I am, to have shown, at least, how a
minute investigation of the geological phenomena of a restricted
locality may lead to a better understanding of the origin of the geo-
graphical features of a country. .

But let me repeat that it were a great mistake to ascribe the
present form of Lake Superior to any single geological event. Its
position in the main is no doubt determined by a dislocation between
the primitive range north and the sedimentary deposit south.

But the working out of the details of its present form is owing to
a series of injections of trap dykes of different characters, traversing
the older rocks, in various directions, which, from their mineralogical
differences, have no doubt been produced at different successive
periods.

The diversity of rocks which occur on Lake Superior is very great,
and there are varieties observed there which seem to be peculiar to
that district, presenting innumerable transitions from, one to another,
of which the Alps even do not present more extensive examples.

Of these we have new red sandstone passing into porphyries,
into quartzites, granites, and gneiss, the metamorphism being more or
less perfect, so that the stratification is sometimes still preserved, or
passes gradually into absolutely massive rocks. Again, the dykes
intersect other rocks almost without altering them, or the alterations
in the immediate contact are so intense as to leave no precise lines
of demarcation between the dyke and the injected rock. But here
again, the phenomena are so complicated, that unless the illustration
be accompanied by a very detailed map it were useless to enter into
more minute descriptions.

426 LAKE SUPERIOR.

The collections I have made of these rocks are sufficiently exten-
sive to afford materials for such an illustration, and I may, perhaps,
on another occasion, publish a more detailed account of the geological
features of the northern shores, unless the expected publication of
the geological survey of Canada by Mr. Logan, renders this essay
superfluous.

I would here acknowledge the benefit I have derived in my in-
vestigations from the published reports of this survey, and also from
the verbal communications of Mr. McLeod of Sault St. Marie. The
rocks which occur on the northern shores are so characteristic that
they cannot be mistaken, and even should the materials which I
have collected not be published more in full, they will at all events
afford to those who study the geological distribution of erratic bould-
ers, valuable means of comparison, which will show that most of the
erratics which occur in the northern parts of the United States are
derived from the primitive range extending north of the lakes reach-
ing along Canada and ^he United States to the Atlantic Ocean.

Among these rocks there is a variety of deep red felspar por-
phyry speckled with epidote, which, from its brilliant color, partic-
ularly attracts attention, and which occurs all along the northern
shore from the Pic to Thunder Bay. This variety I have not
observed farther east, and it may perhaps be taken as a guide to
ascertain the range of erratics derived from the northern shore of
Lake Superior.

I

GEOLOGICAL RELATIONS OF THE VARIOUS COPPER
DEPOSITS OF LAKE SUPERIOR.

THE general distribution of the different copper ores in the region
of Lake Superior, presents some facts which seem to me to have a
direct bearing upon the theory of their origin. It is a very remark-
able circumstance that the largest masses of native copper should
occur upon Point Keewenaw, and that the non-metallic ores should
be diffused at various distances from the central region where the
largest masses of native metallic copper occur. The various sul-
phurets and carbonates are found on the northern shores and about
Lake Huron, in far greater proportion, and over a wider extent, than
anyAvhcre nearer the metallic centre. The black oxide itself is
found beyond the limits of the large metallic masses, and nearer to
them than the other ores. I cannot help thinking that this particu-
lar distribution has direct reference to the manner in which these
various copper ores were diffused in the country where they occur.
They seem to me clearly to indicate that the native copper is all
plutonic ; that its larger masses were thrown up in a melted state ;
and that from the main fissure through which they have found their
way, they spread in smaller injections at considerable distances ; but
upon the larger masses in the central focus, the surrounding rocks
could have little influence. New chemical combinations could hardly
be formed between so compact masses, presenting, in comparison
with their bulk, a small surface for contact with other mineral sub-
stances capable of being chemically combined with the copper. But
where, at a distance, the mass was diffused in smaller proportions into

428 LAKE SUPERIOR.

innumerable minute fissures, and thus presented a comparatively
large surface of contact with the surrounding rocks, there the most
diversified combinations could be formed, and thus the various ores
appear in this characteristic distribution. The relations which these
ores bear to the rocks in which they are contained, sustain fully this
view, and even the circumstance that the black oxide is found in the
vicinity of the main masses, when the sulphurets and carbonates
occur at greater distances from them, would show that this ore is the
result of the oxidation of some portion of the large metallic masses
exposed more directly to the influence of oxygen in the process of
cooling. Indeed, the phenomena respecting the distribution of the
copper about Lake Superior, in all their natural relations, answer so
fully to this view, that the whole process might easily be reproduced
artificially on a small scale ; and it appears strange to me that so
many doubts can still be expressed respecting the origin of the cop-
per about Lake Superior, and that this great feature of the distribu- ,
tion of its various ores should have been so totally overlooked.

COMPARATIVE

PHYSICAL AND HISTORICAL GEOGRAPHY,

OR, THE STUDY OF

THE EARTH AND ITS INHABITANTS.

A SERIES OF GRADUATED COURSES FOR THE USE OF SCHOOLS.

BY ARNOLD GITYOT,

Late Prof, of Physical Geography and History, Neuchatel, Switzerland, author of 'Earth and Man,' &c.

G. K. §• L. are happy to announce that the above work, which has been under-
taken in compliance with the earnest solicitations of numerous teachers and friends
of education, is in a forward state of preparation. The plan of the author, and
the principal characteristics of this series may be gathered from the following
exposition of the subject : —

A knowledge of the globe we inhabit, whether considered in itself alone, or in its
relations to man, the distribution of the races of men, and the civil divisions of its sur-
face, are subjects of interest too varied, too direct, and too vital, not to command the
attention, and excite the sympathy of the mind, at every period of life.

If Geography has been considered as a dry and often fruitless study, if indeed, to
teach it with success has been considered as one of the most difficult problems in edu-
cation, there is reason to believe that the difficulty lies not in the subject, but in the
method of teaching it.

In most manuals the accumulation of facts, and especially the want of arrange-
ment of them, really corresponding to their connection in nature, renders the study
difficult, and overburdens the memory at the expense of a true and thorough under-
standing of the subject. Hence there is confusion and a want of clear and comprehen-
sive views, and consequently a lack of interest for the student. For if the mind seeks
to comprehend, it is only interested in what appears clear and well connected. To
attain this end it is necessary —

FIRST. To attempt a rigid selection of materials, and to reject from school instruc-
tion all details which have but a transient value, and, on the other hand, to render
prominent, facts of permanent value ; preferring, for instance, the details of Physical
Geography and of Ethnography, to those of Statistics, which may be more fully dwelt
upon subsequently.

SECOND. To distribute geographical instruction throughout the whole course of
education, so as to divide the labor of learning, and to give at the same time to each
period of life the nutriment most appropriate for its intellectual taste and capacity.
To this end, the globe should be studied from the different points of view successively,

Graduating each view to the capacity of different classes of students. At first, the iun-
amental outlines alone should be presented, and next, not only additional facts, but
a deeper understanding of their connection, and so on ; and thus, by a regular and
natural path, a full and intelligent knowledge of the globe, in all its relations, will be
finally attained.

THIRD. The comparative method, recently adopted with so much success in
Europe, should always be employed ; for it is by the recognition of resemblances and
differences that the mind seizes upon the true characters, and perceives the natural
relations, and the admirable connection, of the different parts which form the grand
whole ; in a word, gains real knowledge.

The series hereby announced is designed to meet these wants. It will consist of
three courses adapted to the capacity of three different ages and periods of
study. The first is intended for Primary Schools, and for children of from seven to tea
years. The second is adapted for higher schools, and for young persons of from ten to
fifteen years. The third is to be used as a scientific manual in Academies and Colleges.

Each course will be divided into two parts, one of purely Physical Geography, the
other for Ethnography, Statistics, Political and Historical Geography. Each part
will be illustrated by a colored Physical and Political Atlas, prepared expressly for this
purpose, delineating, with the greatest care, the configuration of the surface, and the
other physical phenomena alluded to in the corresponding work, the distribution of the
races of "men, and the political divisions into States. Each part, with the correspond-
ing map, will be sold separately.

The two parts of the first or preparatory course are now in a forward state of prepa-
ration, and will be issued at an early day.

THE EARTH AND MAN:

LECTURES ON COMPARATIVE PHYSICAL GEOGRAPHY, IN ITS RELATION TO THE

HISTORY OP MANKIND.

BY ARNOLD GUYOT.

TRANSLATED FROM THE FRENCH BY PROF. C. C. FELTON.
With Illustrations. 12mo. Price $1.25.

" Those who have been accustomed to regard Geography as a merely descriptive
branch of learning, drier than the remainder biscuit after a voyage, will be delighted
to find this hitherto unattractive pursuit converted into a science, the principles of
which are definite and the results conclusive ; a science that embraces the investigation
of natural laws, and interprets their mode of operation ; which professes to discover in
the rudest forms and apparently confused arrangement of the materials composing the
planet's crust, a new manifestation of the wisdom which has filled the earth with its
riches. * * * To the reader we shall owe no apology, if we have said enough to
excite his curiosity and to persuade him to look to the book itself for further instruc-
tion."— North American Rcrii tr.

" The grand idea of the work is happily expressed by the author, where he calls it
the geographical march of history. * * * The man of science will hail it as a beautiful
sjeneratization from the facts of observation. The Christian, who trusts in a merciful
Providence, will draw courage from it, and hope yet more earnestly for the redemption
of the most degraded portions of mankind. Faith, science, learning, poetry, taste,
in a word, genius, have liberally contributed to the production of the work under review.
Sometimes we feel as if we were studying a treatise on the exact sciences ; at others,
it strikes the ear like an epic poem. Now it reads like history, and now it sounds like
prophecy. It will find readers in whatever language it may be published ; and in the
elegant English dress which it has received from the accomplished pen of the trans-
lator, it will not fail to interest, instruct and inspire." — Christian Examiner.

" A copy of this volume reached us at too late an hour for an extended notice. The
work is one of high merit, exhibiting a wide range of knowledge, great research, and a
philosophical spirit of investigation. Its perusal will well repay the most learned in
such subjects, and give new views to all, of man's relation to the globe he inhabits." —
Silliman's Journal, July, 1849.

PROSPECTUS.

THE ANNUAL OF SCIENTIFIC DISCOVERY is designed for all those
who desire to keep pace with the advancement of Science and Art.
The great and daily increasing number of discoveries in the different
departments of science is such, and the announcement of them is scat-
tered through such a multitude of secular and scientific publications,
that it is very difficult for any one to obtain a satisfactory survey of
them, even had he access to all these publications. But the Scientific
Journals, especially those of Europe, besides being many of them in
foreign languages, have a very limited circulation in this country, and
are therefore accessible to but very few. It is evident, then, that an
annual publication, giving a complete and condensed view of the
progress of discovery in every branch of Science and Art, being, in
fact, the Spirit of the Scientific Journals of the year, systematically
arranged, so as to present at one view all the new discoveries, useful
inventions, and improved processes of the past year, must be a most
acceptable volume to every one, and greatly facilitate the diffusion of

PROSPECTUS.

useful knowledge. As tliis work will be issued annually, the reading
public may easily and promptly possess themselves of the most im-
portant facts discovered or announced in these departments, from year
to year.

The editors are so situated as to have access to all the scientific
publications of America, Great Britain, France, and Germany ; and
have also received, for the present volume, the approbation as well
as the counsel and personal contributions of many of the ablest scien-
tific men in this country, among whom are PROFESSORS AGASSIZ,
HORSFORD, and WYMAN, of Harvard University, and they have the
promise in future, from many scientific gentlemen, of articles not pre-
viously published elsewhere. They have not confined themselves to
an examination of Scientific Journals and Reports, but have drawn
from every source which furnished any thing of scientific interest.
For those who have occasion for still further researches, they have
furnished a copious Index to the scientific articles in the American
and European Journals; and, moreover, they have prepared a list of
all books pertaining to Science which have appeared originally, or by
republication, in the United States, during the year. A classified List
of Patents, and brief obituaries of men distinguished in Science or
Art, who have recently died, render the work still more complete.
They have also taken great pains to make the General Index to the
whole as full and correct as possible.

It will thus be seen, that the plan of the " ANNUAL OF SCIENTIFIC
DISCOVERY " is well designed to make it what it purports to be, a sub-
stantial summary of the discoveries in Science and Art ; and no pains
have been spared on the part of the editors to fulfil the design, and
render it worthy of patronage.

As the work is not intended for scientific men exclusively, but to
meet the wants of the general reader, it has been the aim of the edi-
tors that the articles should be brief and intelligible to all ; and to give
authenticity, the source from whence the information is derived is
generally stated. Although they have used all diligence to render
this first issue as complete as possible, in its design and execution, yet
they hope that experience, and the promised aid and cooperation from
the many gentlemen interested in its success, will enable them in fu-
ture to improve both on the plan and the details.

The work in manuscript has been submitted to several distinguished
gentlemen, to judge of its merits, and they have given their unquali-
fied approbation of the plan and its execution. We subjoin extracts
from letters received from some of these gentlemen.

ANNUAL OF SCIENTIFIC DISCOVERY.

Ill

RECOMMENDATIONS.

From the Prof, of Zoology and Geology, Cambridge.
The publication of annual reports giving short abstracts of the im-
portant discoveries and improvements made in the different branches
of the useful arts, and embracing also an account of the general prog-
ress of Science, has proved so eminently useful, that wherever- cir-
cumstances have favored such publications, they have been found
equally beneficial to those engaged in scientific pursuits, and to the
community at large. Such reports have, for a considerable period, ap-
peared in many parts of Europe, under various titles, either upon spe-
cial branches of science, or covering its whole ground ; but no similar
work has, I believe, hitherto made its appearance in this country.
An undertaking like the Annual of Scientific Discovery, which is in-
tended to give, from year to year, an abstract of the progress of Sci-
ence and Art, cannot fail to be highly acceptable in this country, while
it will at the same time contribute to elevate the standard of American
activity and research abroad, where the proceedings of scientific men
on this side of the Atlantic are not generally so well known as they
ought to be. It therefore gives me great pleasure to say, that in my
opinion the editors of the present work, one of whom, as a member of
the Lawrence Scientific School, at Cambridge, has been under my
personal instruction, are fully qualified to execute the difficult task of
preparing such an abstract with credit, both to themselves and to the
country. Having examined in manuscript a considerable proportion
of the first volume, I can but highly recommend it. As it is designed
to meet a want extensively felt, I hope its reception will be such, that
the editors may be encouraged to continue it annually.

LOUIS AGASSIZ.

From the Prof, of Chemistry in the Lawrence Scientific School.

I have examined, somewhat in detail, the manuscript of the Annual
of Scientific Discovery, and take great pleasure in bearing testimony to
the fidelity with which the work has been prepared. The editors, one
of whom has prosecuted experimental chemistry in my laboratory with
the highest success, are eminently qualified to undertake such a work.

As a compendium of the new and useful truths contributed to the
stock of human knowledge during the past year, presented in a form
acceptable to the general reader, and at the same time so systematic
and complete, as to be of great service to the student of science, it
will be an honor to our country, and cannot fail to be appreciated and
liberally patronized by a discerning public. E. N. HORSFORD.

IV ANNUAL OF SCIENTIFIC DISCOVERY.

From the Prof, of Comparative Anatomy, Harvard University.

I have examined the zoological portion of the Annual of Scientific
Discovery, which contains a faithful account of the progress recently
made in this department of natural science. It is a work of great
value in all its departments, containing, as it does, a record of the va-
rious discoveries made during the past year.

J. WYMAN.

From Doctor Gould, Boston.

Having seen the Prospectus of the " Annual of Scientific Discov-
ery," and having also glanced at a considerable portion of the manu-
script, I am confident that a work on the plan proposed will be of the
highest value to the community ; and I am pleased that it has been
undertaken. The American mind is eminently inventive, and, of
course, specially interested in the progress of discovery. This work
will bring within a convenient compass the very information wanted.
My acquaintance with the editors and the facilities they enjoy gives
assurance that the work will be well digested, and will become increas-
ingly interesting and valuable from year to year.

AUGUSTUS A. GOULD.

From Lieut. Maury, U. S. Navy.

National Observatory, Washington.
Gentlemen, —

Such a work as you propose to publish and make the " Annual of
Scientific Discovery," is a desideratum. It will be useful and valu-
able to all classes, and I shall be glad to see it make its appearance.

Respectfully yours,

M. F. MAURY.

GF8 The work will hereafter le published annually on the first of
March, and will form a handsome duodecimo volume, of about 360
pages, with an engraved likeness of some distinguished man of science.

THE FRENCH REVOLUTIONS,

From 1789 to 1848. By T. W. REDHEAD. 3 volumes. 75c. each.

" The author appears to have prepared himself for his task by a careful examination of the best
'• authorities— the writings of the actors in these various scenes ; and lie has given the results of his
' examination in a style attractive for simplicity, directness and purity. It is the must comprehensive
and valuable work OH the subject that the general reader can lind."— American Traveller.

MODERN FRENCH LITERATURE:

By L. RAYMOND DE VERICOUK, formerly lecturer in the Royal Athcnreum of Paris,
member of the Institute of France, &c. American edition, revised, with notes, by WM.
S. CHASE. With a portrait of LAMARTINE. $1.25.

" This is the only complete treatise of tha kind on this subject, either in French or English, and
' has received the highest commendation. Mr. Chase is well qualified to introduce the work to the
• public. The work cannot fail to be both useful and popular." — New-York Eoeaing Post.

CYCLOPAEDIA OF ENGLISH LITERATURE :

A selection of the choicest productions of English authors, from the earliest to the present
time; connected by a Critical and Biographical History. Edited by ROBERT CHAM-
BERS, assisted by ROBERT CARRUTHERS, and other eminent gentlemen. In 2 vols.,
with upwards of three hundred elegant illustrations. $5,00, cloth.

\^=" A great variety of extra bindings at proportionate prices.

VThe publishers would state, that, besides the numerous pictorial illustrations in the English edi-
tion, they have greatly enriched the work by the addition of fine steel and mezzotint engravings of
the heads of Shakspeare, Addison, Byron ; a full length portrait of Dr. Johnson, and a beautiful
scenic representation of Oliver Goldsmith and Dr. Johnson. These important and elegant additions,
together with superior paper and binding, mast give the AMERICAS edition a decided preference over
the English.

"\Ve hail with peculiar pleasure the appearance of this work, and more especially its republication
in this country at a price which places it within the reach of a great number of readi-rs. We have
been inundated by a stream of cheap reprints, tending to corrupt the morals and vitiate the taste of
our community, and we are pleased that the publishers have still sufficient faith in the parity of both,
to induce them to incur the large outlay which the production of the work before us must have
occasioned, and for which they can expect to be remunerated only by a very extensive sale."

" The selections given by Mr. Chambers, from the works of the early English writers, are copious
and judiciously made. ****** \\re s|iaii conclude as we commenced, with expressing a hope that
the publication which has called forth our remarks will exert an influence in directing the attention
of the public to the literature of our forefathers.— North American Review.

THE ELEMENTS OF MORAL SCIENCE :

By FRANCIS WAYLAND, D. D., President of Brown University, and Professor of Moral
Philosophy. Thirtieth Thousand. 12mo. $1.25.

"The work has been read by me attentively and thoroughly, and I think very highly of it. The
author himself is one of the most estimable of men, and I do not know of any ethical treatise, in which
our duties to God and to our fellow-men arc laid down with more precision, simplicity, clearness,
energy, and truth."— Hon. James Kent, late Chancellor of New-York.

" We have been greatly pleased with the method which President Wayland has adopted ; he goes
back to the simplest and most fundamental principles ; and, in the statement of his views, he unites
perspicuity with conciseness and precision. In all the author's leading fundamental principles we
entirely concur. ' '—Biblical Rej>ository.

MORAL SCIENCE, ABRIDGED,

By the Author, and adapted to the use of Schools and Academies. Twenty-fifth
Thousand. 18mo. 50c.

"Dr. Wayland has published an abridgment of his work, for the use of schools. Of this step we
can hardly speak too highly. It is more than time that the study of moral philosophy should be intro-
duced into all our institutions of education. We are happy to see the way so auspiciously opened for
such an Introduction. It has been not merely abridged, but also re-written. We cannot but regard
the labor as well bestowed. "—North American Review.

"We speak that we do know, when we express our high estimate of Dr. Wayland's ability In teaching
Moral Philosophy, whether orally or by the book. Having listened to his instructions, in this inter-
esting department, we can attest how ibfty are the principles, how exact and severe the argumenta-
tion, how appropriate and strong the illustrations v hich characterize his system and enforce it on the
mind." — The Christian Witness.

ELEMENTS OF POLITICAL ECONOMY.

By FRANCIS WAYLAND, D. D., President of Brown University. Sixteenth Thousand.
12mo. Cloth. $1.25.

" His object has been to write a book, which any one who chooses may understand. He has,
therefore, labored to express the general principles in the plainest manner possible, and to illustrate
them by cases with which every person is familiar. It has been to the author a source of regret, that
the course of discussion in the following pages, has, unavoidably, led him over ground which has
frequently been the arena of political controversy. In all such cases, he has endeavored to state
what seemed to him to be truth, without fear, favor, or affection. He is conscious to himself of no
bias towards any party whatever, and he thinks that he who will read the whole work, will be con-
vinced that he has been Influenced by none."— Extract from the Preface.

POLITICAL ECONOMY, ABRIDGED,

By the Author, and adapted to the use of Schools and Academies. Seventh Thousand.
18mo. 50c.

"An abridgment of this clear, common sense work, designed for the use of academies, Is just
published. We rejoice to see such treatises spreading among the people ; and we urge all who would
be intelligent freemen, to read them."— New- York Transcript.

"We can say, with safety, that the topics are well selected and arranged ; that the author's name
Is a guarantee for more than usual excellence. We wish it an extensive circulation."— N.Y.Obs.

THOUGHTS ON THE PRESENT COLLEGIATE SYSTEM

In the United States. By FRANCIS WAYLAND, D. D. 50c.

"These Thoughts come from a source entitled to a very respectful attention ; and as the author
goes over the whole ground of collegiate education, criticising freely all the arrangements in every
department and in all their bearings, the book is very full of matter. We hope it will prove the
beginning of a thorough discussion."

WAYLAND'S UNIVERSITY SERMONS ;

Delivered in the Chapel of Brown University, on many of the moral and religious topics
of the day. By FRAKCIS WAYLAND, D. D. 12mo. cloth. $1.25.

CLASSICAL STUDIES.

Essays on Ancient Literature and Art. With the Biography and Correspondence of
eminent Philologists. By BARNAS SEARS, B. B. EDWARDS, and C. C. FELTON. $1.25.

"The object of the accomplished gentlemen who have engaged in its preparation, has been, to
foster and extend among educated men, in this country, the already growing interest in classical studies.
The design is a noble and generous one, and has been executed with a taste and good sense, to do
honor both to the writers and the pul Ushers. The book is one which deserves a place in the library
of every educated man. To those now engaged in classical study It cannot fail to be highly useful,
while to the more advanced scholar it would opon new sources of interest and delight in the unforgot-
teu pursuits of his earlier days."— Providence Journal.

Races of Animals, living and extinct ; with numerous illustrations ; for the use of
Schools and Colleges. Part I. — COMPARATIVE PHYSIOLOGY. By Louis AGASSIZ and
AUGUSTUS A. GOULD. $1.00.

" No work of the same dimensions has ever appeared in the English language, containing so much
new and valuable information on the subject of which it treats."— Prof. James flail, Albany.

"On almost every subject we have scores of new books without new principles, but not so with the
work before us ; indeed several of the highly interesting topics presented and illustrated have no
treatise in the English language. It contains a large amount of valuable information, and will be
studied with profit and interest by those who have made respectable attainments in Natural History,
as well as by those just commencing this science. This volume is finely executed, and should find a
place In every library. As a text book for schools and colleges it is far superior to any work before the
public." — New-York District School Journal.

THE CICERONIAN:

Or the Prussian Method of Teaching the Latin Language. Adapted to the use of
American Schools. By B. SEARS, Secr'y Massachusetts Board of Education. 50c.

From the Professors of Harvard University.

" If the book required any other recommendation besides that of being the work of so thorough
and experienced a scholar as Dr. Sears, it would be this : that the system illustrated in it is not a mere
theory, but has been practically tested by many able instructors in Germany. We wish that the same
trial may be made here." CHARLES BECK,

C. C. FELTON.

MEMORIA TECHNICA:

Or the Art of Abbreviating those Studies which give the greatest labor to the Memory.
By L. D. JOHNSON. Third Edition. 60c.

"We feel no hesitation in recommending this work to the deliberate attention of teachers, and the
guardians of youth. We learn that it is received into several schools in Boston, and used as an
auxiliary help to the studies now pursued by the pupils."— Boston Courier.

" The ' Memoria Technlca ' is now studied in some of our best schools ; and the system taught In
it appears to be much approved by those who have made trial of it."— Evening Traveller.

THE YOUNG LADIES' CLASS BOOK :

A Selection of Lessons for Reading, in Prose and Verse. By E. BAILEY, A. M.
12mo. sheep. 83Jc.

" The reading books prepared for academic use are often unsuitable for females. We are glad,
therefore, to perceive that an attempt has been made to supply the deficiency ; and we believe that
the task has been faithfully and successfully accomplished. The selections are judicious and chaste ;
andsofar as they have any moral bearing, appear to be unexceptionable."— Education Reporter.

From E. Bailey, Principal of the Young Ladies' High School, Boston.

From E. Ifinckley, Professor of Mathematics in Maryland University.

" I am much Indebted to you for a copy of the First Book in Astronomy. It is a work of utility
and merit, far superior to any other which I have seen. The author has selected his topics with
great judgment, — arranged them in admirable order, — exhibited them in a style and manner at once
tasteful and philosophical. Nothing seems wanting, —nothing redundant. It is truly a very beauti-
ful and attractive book, calculated to afford both pleasure and profit to all who may enjoy the advan-
tage of perusing it."

From Rev. J. Adams, President of Charleston College, S. C.

" I have been highly gratified with the perusal of vour edition of Conversations on Natural Philoso-
phy. The Questions! Notes, and Explanations of Terms, are valuable additions to the work, and
make this edition superior to any other with which I am acquainted. I shall recommend it wherever

much prayer. Its style is, like the country which gave it birth, beautiful, varied, finished and every-
where delightful. But the style of this work is its smallest excellence. It will be read : it ought

" This valuable edition is printed from English plates, and is a full and fair copy of all that Is valu-
able in Cruden as a Concordance. The principal variation from the larger book consists in the exclu-
sion of the Bible Dictionary, which has long been an incumbrance, and the accuracy and value of
which have befn depreciated by works of later date, containing recent discoveries, facts, and opinions,
unknown to Cruden. The condensation of the quotations of Scripture, arranged under their most
obvious heads, while it diminishes the bulk of the work, greatly facilitates the finding of any required
passage."

THE SOCIAL PSALMIST;

A NEW SELECTION OF HYMNS FOR CONFERENCE MEETINGS AND FAMILY WORSHIP,
BY BARON STOW AND S. F. SMITH.

is- This selection has been in preparation nearly five years, — during which time it has been sub-
jected to repeated examination and careful revision. The object In its preparation has been to furnish
a selection of choice Hymns, for the Vestry and the Family Circle, of moderate size and at trifling
expense, exactly suited to the various stages and conditions of the conference, and other devotional
meetings usually held In the Conference Room, as well as in Family Worship. Hymns, for instance,
on topics embracing prayer, praise, warning, invitation, entreaty, regeneration, repentance, faith,
times of declension, times of revival, receiving and dismissing members ; the Church in prosperity,
and in adversity ; Missionary, Sabbath School, and maternal meetings; meeting and parting, sick-
ness and health, opening and closing year ; brevity of time; death, judgment, heaven, <fcc. It has
been the aim to supply hymns not only of elevated poetic and musical merit, but of true devotional
spirit. A selection of some of the choicest hymns in the Psalmist, adapted to the design of this
book, will here be found, together with several new hymns, as well as those long familiar in the con-
ference meeting, and hallowed by early associations of home, and social prayer. Their familiarity,
instead of being an objection to them, is their highest praise. That they have expressed the devout
aspirations of those who have passed on to the worship of the heavenly temple, gives them a charm
which compositions wholly new could not claim. In the minds of different Christians, we believe
that most of the hymns in this book will summon up some sweet and holy recollections.

The work contains 350 Hymns, besides Doxologies in various meters, not numbered In the list of
hymns. They are the productions of 134 different authors ; 115 are by Watts, 18 by Steele, 17 by
Doddridge, 14 by Newton, 9 by Wesley, 5 each by Cowper, Fawcett, Kelly, and Smith, 4 each by
Heber Beddome, Stennett and Toplady, and others by Swain, Montgomery, Hart, Dwight, Bar-
bauld, Hyde, Reed, Heginbotham, Grant, Cennick, Oliver, Edmeston, Kenn, De Fleury, Scott,
Dobell, Raffles, Pitt, Noel, Medley, Cotton, Ryland, Williams, Boden, Cottreil, Logan, Conden
Collyer, Milman, Kirkham, White, Collins, Robinson, Duncan, Stowell, Cobbin, Kingsbury, Thornby,
Allen, Grigg, &c. There is a large variety of every description of meter, embracing 83 Long, 119
Common, 54 Short, and 94 of various peculiar meters.

It was first contemplated having Music in the volume, but on consultation and reflection it was
deemed unadvisable, as it must necessarily add to the size and expense of the book, and music not
familiar enough to sing in social worship without notes is of little avail, and is seldom used by those
even unacquainted with music, and most of those who usually sing in the conference meeting are
entirely unacquainted with the rudiments of music, and consequently are in no way benefltted by this
addition ; and not unfrequcntly the spirit of devotion is retarded, by the use of tunes not familiar to
those who usually join in tills favorite soul-stirring service.

The work contains three valuable Indexes ; an Index of First Lines, a General Index, and a very full
Particular Index of Subjects.

The type, and size of the page, are the same as the 18mo. , or pew size of the Psalmist. It is printed
on good paper, and strongly bound In sheep, and is afforded at the very low price of twenty-five cents
per copy, and 2.50 per dozen.

93- Copies for examination furnished clergymen gratis, on application to the publishers. The work,
n paper covers, can be sent by mail at a trifling expense for postage.

TOUCHING THE

STRUCTURE, DEVELOPMENT, DISTRIBUTION, & NATURAL ARRANGEMENT

OF THE

RACES OF ANIMALS, LIVING AND EXTINCT:

WITH NUMEROUS ILLUSTRATIONS, FOR THE USE OF SCHOOLS AND COLLEGES.

PART 1.— COMPARATIVE PHYSIOLOGY:

— BY —
LOUIS AGASSIZ AND AUGUSTUS A. GOULD.

PRICE, ONE DOLLAR.

The design of this work is to furnish an epitome of the leading principles of the science
of ZOOLOGY, as deduced from the present state of knowledge, so illustrated as to be
intelligible to the beginning student. No similar treatise now exists in this country, and,
indetd, some of the topics have not been touched upon in the language, unless in a
strictly technical form, and in scattered articles. It has been highly commended, by the
most eminent men of science, and by the public press. A few of which are here given,
together with a sample of the cuts illustrating the work.

" This work has been expected with great interest. It is not simply a system by which
we are taught the classification of Animals, but it is really what it professes to be — the
' Principles of Zoology,' carrying us on, step by step, from the simplest truths to the
comprehension of that infinite plan which the Author of Nature has established. . -
This book places us in possession of information half a century in advance of all our
elementary works on this subject. ... No work of the same dimensions has ever
appeared in the English language, containing so much new and valuable information on
the subject of which it treats." — Professor James Hall, Albany.

PRINCIPLES OF ZOOLOGY.

" A work emanating from so high a source as the
' Principles of Zoology,' hardly requires commendation
to give it currency. The public have become acquainted
with the eminent abilities of Prof. Agassiz through his
lectures, and are aware of his vast learning, wide reach of
mind, and popular mode of illustrating scientific subjects.
In the preparation of this work, he has had an able coad-
jutor in Dr. A. A. Gould, a frequent contributor to the Transactions of
the Boston Society of Natural History, and at present engaged upon the
department of Conchology, for the publication of the late exploring expe-
dition. The volume is prepared for the student in zoological science ; it is
simple and elementary in its style, full in its illustrations, comprehensive
in its range, yet well condensed, and brought into the narrow compass
requisite for the purpose intended." — Sillimaii's Journal.

" The reading of the work has afforded us double the satisfaction it would otherwise
have done, on account of the implicit confidence we felt in the statements and illustra-
trations of the talented authors.

Besides what we have already written, we cannot help urging readers generally, and
especially those who are collecting libraries and are fond of good books, to add this to
their catalogue." — Christian World, Boston.

" Such books as this fasten upon our

minds the disagreeable impression that we

have come into the worm half a century

too early. The schoolboys of the next gen-
i eration can scarcely escape, even with great
| care, the catastrophe of becoming learned.

The volume before us must introduce a new

epoch in the study of this branch of natural

science. It combines all the essential ele-
ments of a good text-book ; being at once

comprehensive, even to exhaustion of the subject, yet concise
and popular. The beauty of the paper, and typography, and illustrations, will aid the
fascination which the contents exert upon the mind. A single glance at a chapter on
Embryology, bound vs with a spell which we could not shale off, till we had baked through
the volume. The names of the authors are vouchers for the merits of the work. —
Professor Agassiz is without a rival in his department of science. His associate is widely
known by his valuable contributions to the Conchology of Massachusetts, which have
won favorable notice from the savans of Europe. We hope the approbation of the public
substantially expressed, may encourage the authors to complete the series so auspiciously
commenced." — Philadelphia Chronicle.

" This work is designed as a text book for Schools and Colleges, and as an exposition
of the interesting science of which it treats, it has many obvious advantages over any
other treatise extant. It is the joint production of two gentlemen, whose researches in
Natural History have enlarged the domain of human knowledge, and one of whom stands
confessedly at the head ot the science of the age. It hence contains the latest and most
approved classifications, with explanations and illustrations, borrowed from the forms of
animated nature, both living and extinct, and made accurate and perfect by the fullest
acquaintance with the present condition of Zoological science. As a text book it is ad-
mirably conceived.

" The presence of Prof. Agassiz in the United States, has given a new impulse to
every branch of Natural History, and we are happy to find him thus associated with Dr.
Gould — one of our leading American naturalists — in explaining his favorite science to
the youth of our Schools and Colleges." — Providence Journal.

" No such work had previously appeared in our country. The production is worthy
of the great names under whose care it has been prepared. Schools and Academies
will find it opens up a new and attractive study for the young ; and in no country is
there a finer field opened np to the naturalist than iu our own." — Christian Alliance, Bos-
ton.

"A new and highly valuable publication, intended for a school book, but which will

be found equally interesting and important for all to study Such a work as this

has long been a great desideratum, and we rejoice that a want so strongly felt, has now,
at length, been so well and so completely supplied." — .fiostow Atlas.

" The work is admirably adapted to the use of schools and colleges, and ought to be
made a study in all our higher seminaries, both male and female." — New-York Observer.

" To the testimony which is furnished by their distinguished
scholarship, we may add, however, that the classifications of the
work are so admirably arranged, and its des-
criptions given with so much simplicity and
clearness of language, that the book cannot
fail of its practical aim — to facilitate the pro-
gress of the beginning student. It is a work
for schools." — New-York Recorder.

" The announcement of this work some time
ago, as being in a course of preparation, ex-
cited a high degree of interest among teachers,
students, and the friends of science. The names
of its authors gave ample assurance that it was no compilation drawn from other works
no mere reconstruction of existing materials. The work will undoubtedly meet the
expectations that have been formed of it, and already it has been adopted as a text-book
in several colleges. It breaks new ground; as is snid in the preface, 'some of its topics
have not been touched upon in the language, unless in a strictly technical form, and in
scattered articles.' The volume exhibits throughout great labor and care in preparing it
for the public eye, and for the use of students. As it has no rival, we suppose its adop-
tion will be almost universal in literary institutions, and it will do much to awaken in the
minds of multitudes an enthusiastic love of natural history." — Christian Reflector
Watchman.

" This is entirely a new field in Ameri-
can elementary literature, no similar
treatise existing in this country. At first
sight, the work appeared to us too ab-
struse for beginners, and for the use of
those whom the authors aim to benefit —
the scholars in our common schools. A
more careful examination convinces us
that any teacher or scholar, who is in
earnest to understand the subject, will
find the application necessary at the com-
mencement comparatively trifling, while the subsequent benefit will be immense. This
is the first volume of the work, and is devoted to Comparative Physiology, on which branch
it is exceedingly complete. It is freely illustrated with the necessary wood cuts. The
names of the authors will be a higher guarantee for scientific accuracy than any judgment
we might pronounce." — New- York Commercial Advertiser.

"It is designed chiefly for the use of schools and colleges, and as an epitome of the
subject on which it treats, contains more in a small space, than any book of the kind that
has yet fallen under our notice." — Saturday Gleaner, Philadelphia.

PRINCIPLES OF ZOOLOGY.

" On almost every subject we have scores of new books without new principles, but
not so with the work before us ; indeed several of the highly interesting topics presented
and illustrated have no treatise in the English language. It contains a large amount of
valuable information, and will be studied With profit and interest by those who have made
respectable attainments in Natural History, as well as by those just commencirfg this
science. This volume is finely executed, and should find a place in every library. As a
text-book for schools and colleges it is far superior to any work before the public." —
New- York District School Journal.

" Professor Agassiz stands confes-
sedly at the head of Zoological science,
and his coming among us is everywhere
hailed with delight and enthusiasm,
and the influence of his mission is
everywhere felt already, and it will
continue for a century to come. Dr.
Gould is one of the most indefatigable
and accurate investigators in natural
science of our country, and we greet
with real pleasure the association of
his name with that of Prof. Agassiz in
the preparation of this "work.

Our space will not allow anything

like a review of this admirable and to us novel work. The plan is
quite unlike those elementary works which teach us the mode of clas-
sifying animals by a few important characteristics. It commences by
explaining the sphere and fundamental prinicples of Zoology, and
follows by showing what are the general properties of organized bod-
ies ; the functions of organs in animal life ; the nervous system, the
senses, motion, nutrition, circulation, &c. K^ The diopter on Emlry-
ology alone is of more actual interest in philosophical Zoijloyy, than all*
that has ever appeared on the. subject of Zoology, in our (ountry. And as we before re-
marked, this knowledge is nowhere else to be had in the English language. The geograph-
ical distribution of animals forms another important feature of very deep and general
interest." — Albany Argus.

" I have read with the greatest satisfaction the volume on the principles of Zoology.
It is such a book as might be expected from the eminent ability of the authors, Professor
Agassiz and Dr. Gould. So far as I know it is the most comprehensive and philosophical
elementary treatise on the subjects of which it treats, which has yet appeared.

It is well adapted to the purpose of being used as a text-book in schools, and I shall
employ it in preference to any other in my own school, whenever I have a class in the
elements of Natural History, and I can strongly recommend it to other teachers." — Gcorijc
