THE GALA DAYS OF BIRDS
Migration is over, and the great influx
of birds which last month filled every tree and bush
is now distributed over field and wood, from our dooryard
and lintel vine to the furthermost limits of northern
exploration; birds, perhaps, having discovered the
pole long years ago. Now every feather and plume
is at its brightest and full development; for must
not the fastidious females be sought and won?
And now the great struggle of the
year is at hand, the supreme moment for which thousands
of throats have been vibrating with whispered rehearsals
of trills and songs, and for which the dangers that
threaten the acquisition of bright colours and long,
inconvenient plumes and ornaments have been patiently
undergone. Now, if all goes well and his song
is clear, if his crest and gorgeous splashes of tints
and shades are fresh and shining with the gloss of
health, then the feathered lover may hope, indeed,
that the little brown mate may look with favour upon
dance, song, or antic and the home is become
a reality. In some instances this home is for
only one short season, when the two part, probably
forever; but in other cases the choice is for life.
But if his rival is stronger, handsomer,
and victorious, what then? Alas, the
song dies in his throat, plumes hang crestfallen, and
the disconsolate creature must creep about through
tangles and brush, watching from a distance the nest-building,
the delights of home life which fate has forbidden.
But the poor bachelor need not by any means lose hope;
for on all sides dangers threaten his happy rival cats,
snakes, jays, hawks, owls, and boys. Hundreds
of birds must pay for their victory with their lives,
and then the once discarded suitors are quickly summoned
by the widows; and these step-fathers, no whit chagrined
at playing second fiddle, fill up the ranks, and work
for the young birds as if they were their own offspring.
There is an unsolved mystery about
the tragedies and comedies that go on every spring.
Usually every female bird has several suitors, of which
one is accepted. When the death of this mate
occurs, within a day or two another is found; and
this may be repeated a dozen times in succession.
Not only this, but when a female bird is killed, her
mate is generally able at once somewhere, somehow,
to find another to take her place. Why these
unmated males and females remain single until they
are needed is something that has never been explained.
The theme of the courtship of birds
is marvellously varied and comparatively little understood.
Who would think that when our bald eagle, of national
fame, seeks to win his mate, his ardour takes the form
of an undignified galloping dance, round and round
her from branch to branch! Hardly less ridiculous to
our eyes is the elaborate performance of
our most common woodpecker, the flicker, or high-hole.
Two or three male birds scrape and bow and pose and
chatter about the demure female, outrageously undignified
as compared with their usual behaviour. They do
everything save twirl their black moustaches!
In the mating season some birds have
beauties which are ordinarily concealed. Such
is the male ruby-crowned kinglet, garbed in gray and
green, the two sexes identical, except for the scarlet
touch on the crown of the male, which, at courting
time, he raises and expands. Even the iris of
some birds changes and brightens in colour at the breeding
season; while in others there appear about the base
of the bill horny parts, which in a month or two fall
off. The scarlet coat of the tanager is perhaps
solely for attracting and holding the attention of
the female, as before winter every feather is shed,
the new plumage being of a dull green, like that of
its mate and its young.
As mystery confronts us everywhere
in nature, so we confess ourselves baffled when we
attempt to explain the most wonderful of all the attributes
of bird courtship song. Birds have
notes to call to one another, to warn of danger, to
express anger and fear; but the highest development
of their vocal efforts seems to be devoted to charming
the females. If birds have a love of music, then
there must be a marvellous diversity of taste among
them, ranging all the way from the shrieking, strident
screams of the parrots and macaws to the tender pathos
of the wood pewee and the hermit thrush.
If birds have not some appreciation
of sweet sounds, then we must consider the many different
songs as mere by-products, excess of vitality which
expresses itself in results, in many cases, strangely
aesthetic and harmonious. A view midway is indefinable
as regards the boundaries covered by each theory.
How much of the peacock’s train or of the thrush’s
song is appreciated by the female? How much is
by-product merely?
In these directions a great field
lies open to the student and lover of birds; but however
we decide for ourselves in regard to the exact meaning
and evolution of song, and what use it subserves among
the birds, we all admit the effect and pleasure it
produces in ourselves. A world without the song
of birds is greatly lacking such is a desert,
where even the harsh croak of a raven is melody.
Perhaps the reason why the songs of
birds give more lasting pleasure than many other things
is that sound is so wonderfully potent to recall days
and scenes of our past life. Like a sunset, the
vision that a certain song brings is different to
each one of us.
To me, the lament of the wood pewee
brings to mind deep, moist places in the Pennsylvania
backwoods; the crescendo of the oven bird awakens
memories of the oaks of the Orange mountains; when
a loon or an olive-sided flycatcher or a white-throat
calls, the lakes and forests of Nova Scotia come vividly
to mind; the cry of a sea-swallow makes real again
the white beaches of Virginia; to me a cardinal has
in its song the feathery lagoons of Florida’s
Indian River, while the shriek of a macaw and its
antithesis, the silvery, interlacing melodies of the
solitaire, spell the farthest barrancas of
Mexico, with the vultures ever circling overhead,
and the smoke clouds of the volcano in the distance.
So sweet, so sweet the calling
of the thrushes,
The calling, cooing, wooing, everywhere;
So sweet the water’s song through
reeds and rushes,
The plover’s piping note, now here,
now there.

TURTLE TRAITS
A turtle, waddling his solitary way
along some watercourse, attracts little attention
apart from that aroused by his clumsy, grotesque shape;
yet few who look upon him are able to give offhand
even a bare half-dozen facts about the humble creature.
Could they give any information at all, it would probably
be limited to two or three usages to which his body
is put such as soup, mandolin picks, and
combs.
In the northeastern part of our own
country we may look for no fewer than eight species
of turtles which are semi-aquatic, living in or near
ponds and streams, while another, the well-known box
tortoise, confines its travels to the uplands and
woods.
There are altogether about two hundred
different kinds of turtles, and they live in all except
the very cold countries of the world. Australia
has the fewest and North and Central America the greatest
number of species. Evolutionists can tell us
little or nothing of the origin of these creatures,
for as far back in geological ages as they are found
fossil (a matter of a little over ten million years),
all are true turtles, not half turtles and half something
else. Crocodiles and alligators, with their hard
leathery coats, come as near to them as do any living
creatures, and when we see a huge snapping turtle come
out of the water and walk about on land, we cannot
fail to be reminded of the fellow with the armoured
back.
Turtles are found on the sea and on
land, the marine forms more properly deserving the
name of turtles; tortoises being those living on land
or in fresh water. We shall use the name turtle
as significant of the whole group. The most natural
method of classifying these creatures is by the way
the head and neck are drawn back under the shell; whether
the head is turned to one side, or drawn straight
back, bending the neck into the letter S shape.
The skull of a turtle is massive,
and some have thick, false roofs on top of the usual
brain box.
The “house” or shell of
a turtle is made up of separate pieces of bone, a
central row along the back and others arranged around
on both sides. These are really pieces of the
skin of the back changed to bone. Our ribs are
directly under the skin of the back, and if this skin
should harden into a bone-like substance, the ribs
would lie flat against it, and this is the case with
the ribs of turtles. So when we marvel that the
ribs of a turtle are on the outside of its body, a
second thought will show us that this is just as true
of us as it is of these reptiles.
This hardening of the skin has brought
about some interesting changes in the body of the
turtle. In all the higher animals, from fishes
up to man, a backbone is of the greatest importance
not only in carrying the nerves and blood-vessels,
but in supporting the entire body. In turtles
alone, the string of vertebrae is unnecessary, the
shell giving all the support needed. So, as Nature
seldom allows unused tissues or organs to remain,
these bones along the back become, in many species,
reduced to a mere thread.
The pieces of bone or horn which go
to make up the shell, although so different in appearance
from the skin, yet have the same life-processes.
Occasionally the shell moults or peels, the outer part
coming off in great flakes. Each piece grows
by the addition of rings of horn at the joints, and
(like the rings of a tree) the age of turtles, except
of very old ones, can be estimated by the number of
circles of horn on each piece. The rings are
very distinct in species which live in temperate climates.
Here they are compelled to hibernate during the winter,
and this cessation of growth marks the intervals between
each ring. In tropical turtles the rings are
either absent or indistinct. It is to this mode
of growth that the spreading of the initials which
are cut into the shell is due, just as letters carved
on the trunks of trees in time broaden and bulge outward.
The shell has the power of regeneration,
and when a portion is crushed or torn away the injured
parts are gradually cast off, and from the surrounding
edges a new covering of horn grows out. One third
of the entire shell has been known to be thus replaced.
Although so slow in their locomotion
and actions, turtles have well-developed senses.
They can see very distinctly, and the power of smell
is especially acute, certain turtles being very discriminating
in the matter of food. They are also very sensitive
to touch, and will react to the least tap on their
shells. Their hearing, however, is more imperfect,
but as during the mating season they have tiny, piping
voices, this sense must be of some use.
Water tortoises can remain beneath
the surface for hours and even days at a time.
In addition to the lungs there are two small sacs
near the tail which allow the animal to use the oxygen
in the water as an aid to breathing.
All turtles lay eggs, the shells of
which are white and generally of a parchment-like
character. They are deposited in the ground or
in the sand, and hatch either by the warmth of the
decaying vegetation or by the heat of the sun.
In temperate countries the eggs remain through the
winter, and the little turtles do not emerge until
the spring. The eggs of turtles are very good
to eat, and the oil contained in them is put to many
uses. In all the countries which they inhabit,
young turtles have a hard time of it; for thousands
of them are devoured by storks, alligators, and fishes.
Even old turtles have many enemies, not the least strange
being jaguars, which watch for them, turn them
on their backs with a flip of the paw, and eat them
at leisure on the half shell, as it were!
Leathery turtles which
live in the sea have been reported weighing
over a thousand pounds! This species is very
rare, and a curious circumstance is that only very
large adults and very small baby individuals have been
seen, the turtles of all intermediate growths keeping
in the deep ocean out of view.
Snapping turtles are among the fiercest
creatures in the world. On leaving the egg their
first instinct is to open their mouths and bite at
something. They feed on almost anything, but when,
in captivity they sometimes refuse to eat, and have
been known to go a year without food, showing no apparent
ill effects. One method which they employ in capturing
their food is interesting. A snapping turtle will
lie quietly at the bottom of a pond or lake, looking
like an old water-soaked log with a branch its
head and neck at one end. From the
tip of the tongue the creature extrudes two small
filaments of a pinkish colour which wriggle about,
bearing a perfect resemblance to the small round worms
of which fishes are so fond. Attracted by these,
fishes swim up to grasp the squirming objects and
are engulfed by the cruel mouth of the angler.
Certain marine turtles have long-fringed appendages
on the head and neck, which, waving about, serve a
similar purpose.
The edible terrapin has, in many places,
become very rare; so that thousands of them are kept
and bred in enclosed areas, or “crawls,”
as they are called. This species is noted for
its curious disposition, and it is often captured
by being attracted by some unusual sound.
The tortoise-shell of commerce is
obtained from the shell of the hawksbill turtle, the
plates of which, being very thin, are heated and welded
together until of the required thickness. The
age to which turtles live has often been exaggerated,
but they are certainly the longest lived of all living
creatures. Individuals from the Galapagos Island
are estimated to be over four hundred years old.
When, in a zoological garden, we see one of these
creatures and study his aged, aged look, as he slowly
and deliberately munches the cabbage which composes
his food, we can well believe that such a being saw
the light of day before Columbus made his memorable
voyage.
He’s his own landlord,
his own tenant; stay
Long as he will, he dreads no Quarter Day.
Himself he boards and lodges; both invites
And feasts himself; sleeps with himself
o’nights.
He spares the upholsterer trouble to procure
Chattels; himself is his own furniture,
Knock when you will, he’s
sure to be at home.
Charles
Lamb.
A HALF-HOUR IN A MARSH
There are little realms all around
of which many of us know nothing. Take, for example,
some marsh within a half-hour’s trolley ride
of any of our cities or towns. Select one where
cat-tails and reeds abound. Mosquitoes and fear
of malaria keep these places free from invasion by
humankind; but if we select some windy day we may
laugh them both to scorn, and we shall be well repaid
for our trip. The birds frequenting these places
are so seldom disturbed that they make only slight
effort to conceal their nests, and we shall find plenty
of the beautiful bird cradles rocking with every passing
breeze.
A windy day will also reveal an interesting
feature of the marsh. The soft, velvety grass,
which abounds in such places, is so pliant and yielding
that it responds to every breath, and each approaching
wave of air is heralded by an advancing curl of the
grass. At our feet these grass-waves intersect
and recede, giving a weird sensation, as if the ground
were moving, or as if we were walking on the water
itself. Where the grass is longer, the record
of some furious gale is permanently fixed swaths
and ripples seeming to roll onward, or to break into
green foam. The simile of a “painted ocean”
is perfectly carried out. There is no other substance,
not even sand, which simulates more exactly the motions
of water than this grass.
In the nearest clump of reeds we notice
several red-winged blackbirds, chattering nervously.
A magnificent male bird, black as night, and with
scarlet epaulets burning on his shoulders, swoops at
us, while his inconspicuous brownish consorts vibrate
above the reeds, some with grubs, some empty mouthed.
They are invariable indexes of what is below them.
We may say with perfect assurance that in that patch
of rushes are two nests, one with young; beyond are
three others, all with eggs.
We find beautiful structures, firm
and round, woven of coarse grasses inside and dried
reeds without, hung between two or three supporting
stalks, or, if it is a fresh-water marsh, sheltered
by long, green fern fronds. The eggs are worthy
of their cradles pearly white in colour,
with scrawls and blotches of dark purple at the larger
end hieroglyphics which only the blackbirds
can translate.
In another nest we find newly hatched
young, looking like large strawberries, their little
naked bodies of a vivid orange colour, with scanty
gray tufts of down here and there. Not far away
is a nest, overflowing with five young birds ready
to fly, which scramble out at our approach and start
boldly off; but as their weak wings give out, they
soon come to grief. We catch one and find that
it has most delicate colours, resembling its mother
in being striped brown and black, although its breast
and under parts are of an unusually beautiful tint a
kind of salmon pink. I never saw this shade elsewhere
in Nature.
Blackbirds are social creatures, and
where we find one nest, four or five others may be
looked for near by. The red-winged blackbird is
a mormón in very fact, and often a solitary male
bird may be seen guarding a colony of three or four
nests, each with an attending female. A sentiment
of altruism seems indeed not unknown, as I have seen
a female give a grub to one of a hungry nestful, before
passing on to brood her own eggs, yet unhatched.
While looking for the blackbirds’
nests we shall come across numerous round, or oval,
masses of dried weeds and grass mice homes
we may think them; and the small, winding entrance
concealed on one side tends to confirm this opinion.
Several will be empty, but when in one our fingers
touch six or eight tiny eggs, our mistake will be apparent.
Long-billed marsh wrens are the architects, and so
fond are they of building that frequently three or
four unused nests are constructed before the little
chocolate jewels are deposited.
If we sit quietly for a few moments,
one of the owners, overcome by wren curiosity, will
appear, clinging to a reed stalk and twitching his
pert, upturned tail, the badge of his family.
Soon he springs up into the air and, bubbling a jumble
of liquid notes, sinks back into the recesses of the
cat-tails. Another and another repeat this until
the marsh rings with their little melodies.
If we seat ourselves and watch quietly
we may possibly behold an episode that is not unusual.
The joyous songs of the little wrens suddenly give
place to cries of fear and anger; and this hubbub increases
until at last we see a sinister ripple flowing through
the reeds, marking the advancing head of a water snake.
The evil eyes of the serpent are bent
upon the nearest nest, and toward it he makes his
way, followed and beset by all the wrens in the vicinity.
Slowly the scaly creature pushes himself up on the
reeds; and as they bend under his weight he makes
his way the more easily along them to the nest.
His head is pushed in at the entrance, but an instant
later the snake twines downward to the water.
The nest was empty. Again he seeks an adjoining
nest, and again is disappointed; and now, a small fish
attracting his attention, he goes off in swift pursuit,
leaving untouched the third nest in sight, that containing
the precious eggs. Thus the apparently useless
industry of the tiny wrens has served an invaluable
end, and the tremulous chorus is again timidly taken
up little hymns of thanksgiving we may
imagine them now.
These and many others are sights which
a half-hour’s tramp, without even wetting our
shoes, may show us. Before we leave, hints of
more deeply hidden secrets of the marsh may perhaps
come to us. A swamp sparrow may show by its actions
that its nest is not far away; from the depths of a
ditch jungle the clatter of some rail comes faintly
to our ears, and the distant croak of a night heron
reaches us from its feeding-grounds, guarded by the
deeper waters.
And what if behind me to westward the wall of
the woods stands high?
The world lies east: how ample, the marsh
and the sea and the sky!
A league and a league of marsh-grass, waist-high,
broad in the blade.
Oh, what is abroad in the marsh and terminal
sea?
Somehow my soul seems suddenly free
From the weighing of fate and the sad discussion
of sin.
Sidney
Lanier.
SECRETS OF THE OCEAN
We are often held spellbound by the
majesty of mountains, and indeed a lofty peak forever
capped with snow, or pouring forth smoke and ashes,
is impressive beyond all terrestrial things.
But the ocean yields to nothing in its grandeur, in
its age, in its ceaseless movement, and the question
remains forever unanswered, “Who shall sound
the mysteries of the sea?” Before the most ancient
of mountains rose from the heart of the earth, the
waves of the sea rolled as now, and though the edges
of the continents shrink and expand, bend into bays
or stretch out into capes, always through all the
ages the sea follows and laps with ripples or booms
with breakers unceasingly upon the shore.
Whether considered from the standpoint
of the scientist, the mere curiosity of the tourist,
or the keen delight of the enthusiastic lover of Nature,
the shore of the sea its sands and waters,
its ever-changing skies and moods is one
of the most interesting spots in the world. The
very bottom of the deep bays near shore dark
and eternally silent, prisoned under the restless
waste of waters is thickly carpeted with
strange and many-coloured forms of animal and vegetable
life. But the beaches and tide-pools over which
the moon-urged tides hold sway in their ceaseless
rise and fall, teem with marvels of Nature’s
handiwork, and every day are restocked and replanted
with new living objects, both arctic and tropical
offerings of each heaving tidal pulse.
Here on the northeastern shores of
our continent one may spend days of leisure or delightful
study among the abundant and ever changing variety
of wonderful living creatures. It is not unlikely
that the enjoyment and absolute novelty of this new
world may enable one to look on these as some of the
most pleasant days of life. I write from the edge
of the restless waters of Fundy, but any rock-strewn
shore will duplicate the marvels.
At high tide the surface of the Bay
is unbroken by rock or shoal, and stretches glittering
in the sunlight from the beach at one’s feet
to where the New Brunswick shore is just visible,
appearing like a low bluish cloud on the horizon.
At times the opposite shore is apparently brought nearer
and made more distinct by a mirage, which inverts it,
together with any ships which are in sight. A
brig may be seen sailing along keel upward, in the
most matter-of-fact way. The surface may anon
be torn by those fearful squalls for which Fundy is
noted, or, calm as a mirror, reflect the blue sky
with an added greenish tinge, troubled only by the
gentle alighting of a gull, the splash of a kingfisher
or occasional osprey, as these dive for their prey,
or the ruffling which shows where a school of mackerel
is passing. This latter sign always sends the
little sailing dories hurrying out, where they beat
back and forth, like shuttles travelling across a
loom, and at each turn a silvery struggling form is
dragged into the boat.
A little distance along the shore
the sandy beach ends and is replaced by huge bare
boulders, scattered and piled in the utmost confusion.
Back of these are scraggly spruces, with branches
which have been so long blown landwards that they
have bent and grown altogether on that side, permanent
weather-vanes of Fundy’s storms. The very
soil in which they began life was blown away, and
their gnarled weather-worn roots hug the rocks, clutching
every crevice as a drowning man would grasp an oar.
On the side away from the bay two or three long, thick
roots stretch far from each tree to the nearest earth-filled
gully, sucking what scanty nourishment they can, for
strength to withstand the winter’s gales yet
another year or decade. Beach-pea and sweet marsh
lavender tint the sand, and stunted fringed orchids
gleam in the coarse grass farther inland. High
up among the rocks, where there is scarcely a handful
of soil, delicate harebells sway and defy the blasts,
enduring because of their very pliancy and weakness.
If we watch awhile we will see a line
of blackish seaweed and wet sand appearing along the
edge of the water, showing that the tide has turned
and begun to recede. In an hour it has ebbed a
considerable distance, and if we clamber down over
the great weather-worn rocks the hardy advance guard
of that wonderful world of life under the water is
seen. Barnacles whiten the top of every rock
which is reached by the tide, although the water may
cover them only a short time each day. But they
flourish here in myriads, and the shorter the chance
they have at the salt water the more frantically their
little feathery feet clutch at the tiny food particles
which float around them. These thousands of tiny
turreted castles are built so closely together that
many are pressed out of shape, paralleling in shape
as in substance the inorganic crystals of the mineral
kingdom. The valved doors are continually opening
and partly closing, and if we listen quietly we can
hear a perpetual shuss! shuss! Is it the creaking
of the tiny hinges? As the last receding wave
splashes them, they shut their folding doors over
a drop or two and remain tightly closed, while perhaps
ten hours of sunlight bake them, or they glisten in
the moonlight for the same length of time, ready at
the first touch of the returning water to open wide
and welcome it.
The thought of their life history
brings to mind how sadly they retrogress as they grow,
hatching as minute free-swimming creatures like tiny
lobsters, and gradually changing to this plant-like
life, sans eyes, sans head, sans
most everything except a stomach and a few pairs of
feathery feet to kick food into it. A few pitiful
traces of nerves are left them. What if there
were enough ganglia to enable them to dream of their
past higher life, in the long intervals of patient
waiting!
A little lower down we come to the
zone of mussels, hanging in clusters like
some strange sea-fruit. Each is attached by strands
of thin silky cables, so tough that they often defy
our utmost efforts to tear a specimen away. How
secure these creatures seem, how safe from all harm,
and yet they have enemies which make havoc among them.
At high tide fishes come and crunch them, shells and
all, and multitudes of carnivorous snails are waiting
to set their file-like tongues at work, which mercilessly
drill through the lime shells, bringing death in a
more subtle but no less certain form. Storms
may tear away the support of these poor mollusks, and
the waves dash them far out of the reach of the tides,
while at low water, crows and gulls use all their
ingenuity to get at their toothsome flesh.
There are no ant-hills in the sea,
but when we turn over a large stone and see scores
upon scores of small black shrimps scurrying around,
the resemblance to those insects is striking.
These little creatures quickly hitch away on their
sides, getting out of sight in a remarkably short
time.
The tide is going down rapidly, and
following it step by step novel sights meet the eye
at every turn, and we begin to realise that in this
narrow strip, claimed alternately by sea and land,
which would be represented on a map by the finest
of hair-lines, there exists a complete world of animated
life, comparing in variety and numbers with the life
in that thinner medium, air. We climb over enormous
boulders, so different in appearance that they would
never be thought to consist of the same material as
those higher up on the shore. These are masses
of wave-worn rock, twenty or thirty feet across, piled
in every imaginable position, and completely covered
with a thick padding of seaweed. Their drapery
of algae hangs in festoons, and if we draw aside these
submarine curtains, scenes from a veritable fairyland
are disclosed. Deep pools of water, clear as
crystal and icy cold, contain creatures both hideous
and beautiful, sombre and iridescent, formless and
of exquisite shape.
The sea-anémones first attract
attention, showing as splashes of scarlet and salmon
among the olive-green seaweed, or in hundreds covering
the entire bottom of a pool with a delicately hued
mist of waving tentacles. As the water leaves
these exposed on the walls of the caves, they lose
their plump appearance and, drawing in their wreath
of tentacles, hang limp and shrivelled, resembling
pieces of water-soaked meat as much as anything.
Submerged in the icy water they are veritable animal-flowers.
Their beauty is indeed well guarded, hidden by the
overhanging seaweed in these caves twenty-five feet
or more below high-water mark.
Here in these beautiful caverns we
may make aquariums, and transplant as many animal-flowers
as we wish. Wherever we place them their fleshy,
snail-like foot spreads out, takes tight hold, and
the creature lives content, patiently waiting for
the Providence of the sea to send food to its many
wide-spread fingers.
Carpeted with pink algae and dainty
sponges, draped with sea-lettuce like green tissue
paper, decorated with strange corallines, these natural
aquariums far surpass any of artificial make.
Although the tide drives us from them sooner or later,
we may return with the sure prospect of finding them
refreshed and perhaps replenished with many new forms.
For often some of the deep-water creatures are held
prisoners in the lower tide-pools, as the water settles,
somewhat as when the glaciers receded northward after
the Ice Age there were left on isolated mountain peaks
traces of the boreal fauna and flora.
If we are interested enough to watch
our anémones we will find much entertainment.
Let us return to our shrimp colonies and bring a handful
to our pool. Drop one in the centre of an anemone
and see how quickly it contracts. The tentacles
bend over it exactly as the sticky hairs of the sun-dew
plant close over a fly. The shrimp struggles for
a moment and is then drawn downward out of sight.
The birth of an anemone is well worth patient watching,
and this may take place in several different ways.
We may see a large individual with a number of tiny
bunches on the sides of the body, and if we keep this
one in a tumbler, before long these protubérances
will be seen to develop a few tentacles and at last
break off as perfect miniature anémones.
Or again, an anemone may draw in its tentacles without
apparent cause, and after a few minutes expand more
widely than ever. Suddenly a movement of the mouth
is seen, and it opens, and one, two, or even a half-dozen
tiny anémones shoot forth. They turn
and roll in the little spurt of water and gradually
settle to the rock alongside of the mother. In
a short time they turn right side up, expand their
absurd little heads, and begin life for themselves.
These animal “buds” may be of all sizes;
some minute ones will be much less developed and look
very unlike the parent. These are able to swim
about for a while, and myriads of them may be born
in an hour. Others, as we have seen, have tentacles
and settle down at once.
Fishes, little and big, are abundant
in the pools, darting here and there among the leathery
fronds of “devils’ aprons,” cavernous-mouthed
angler fish, roly-poly young lump-suckers, lithe butterfish,
and many others.
Moving slowly through the pools are
many beautiful creatures, some so evanescent that
they are only discoverable by the faint shadows which
they cast on the bottom, others suggest animated spheres
of prismatic sunlight. These latter are tiny
jelly-fish, circular hyaline masses of jelly with
eight longitudinal bands, composed of many comb-like
plates, along which iridescent waves of light continually
play. The graceful appearance of these exquisite
creatures is increased by two long, fringed tentacles
streaming behind, drifting at full length or contracting
into numerous coils. The fringe on these streamers
is a series of living hairs an aquatic
cobweb, each active with life, and doing its share
in ensnaring minute atoms of food for its owner.
When dozens of these ctenophores (or comb-bearers)
as they are called, glide slowly to and fro through
a pool, the sight is not soon forgotten. To try
to photograph them is like attempting to portray the
substance of a sunbeam, but patience works wonders,
and even a slightly magnified image of a living jelly
is secured, which shows very distinctly all the details
of its wonderfully simple structure; the pouch, suspended
in the centre of the sphere, which does duty as a
stomach; the sheaths into which the long tentacles
may be so magically packed, and the tiny organ at
the top of this living ball of spun glass, serving,
with its minute weights and springs, as compass, rudder,
and pilot to this little creature, which does not fear
to pit its muscles of jelly against the rush and might
of breaking waves.
Even the individual comb-plates or
rows of oars are plainly seen, although, owing to
their rapid motion, they appear to the naked eye as
a single band of scintillating light. This and
other magnified photographs were obtained by fastening
the lens of a discarded bicycle lantern in a cone
of paper blackened on the inside with shoe-blacking.
With this crude apparatus placed in front of the lens
of the camera, the evanescent beauties of these most
delicate creatures were preserved.
Other equally beautiful forms of jelly-fish
are balloon-shaped. These are Beroe, fitly
named after the daughter of the old god Oceanus.
They, like others of their family, pulsate through
the water, sweeping gracefully along, borne on currents
of their own making.
Passing to other inhabitants of the
pools, we find starfish and sea-urchins everywhere
abundant. Hunched-up groups of the former show
where they are dining in their unique way on unfortunate
sea-snails or anémones, protruding their whole
stomach and thus engulfing their victim. The
urchins strain and stretch with their innumerable sucker-feet,
feeling for something to grasp, and in this laborious
way pull themselves along. The mouth, with the
five so-called teeth, is a conspicuous feature, visible
at the centre of the urchin and surrounded by the greenish
spines. Some of the starfish are covered with
long spines, others are nearly smooth. The colours
are wonderfully varied, red, purple, orange,
yellow, etc.
The stages through which these prickly
skinned animals pass, before they reach the adult
state, are wonderfully curious, and only when they
are seen under the microscope can they be fully appreciated.
A bolting-cloth net drawn through some of the pools
will yield thousands in many stages, and we can take
eggs of the common starfish and watch their growth
in tumblers of water. At first the egg seems
nothing but a tiny round globule of jelly, but soon
a dent or depression appears on one side, which becomes
deeper and deeper until it extends to the centre of
the egg-mass. It is as if we should take a round
ball of putty and gradually press our finger into
it. This pressed-in sac is a kind of primitive
stomach and the entrance is used as a mouth.
After this follows a marvellous succession of changes,
form giving place to form, differing more in appearance
and structure from the five-armed starfish than a
caterpillar differs from a butterfly.
For example, when about eight days
old, another mouth has formed and two series of delicate
cilia or swimming hairs wind around the creature, by
means of which it glides slowly through the water.
The photographs of a starfish of this age show the
stomach with its contents, a dark rounded mass near
the lower portion of the organism. The vibrating
bands which outline the tiny animal are also visible.
The delicacy of structure and difficulty of preserving
these young starfish alive make these pictures of
particular value, especially as they were taken of
the living forms swimming in their natural element.
Each day and almost each hour adds to the complexity
of the little animal, lung tentacles grow out and many
other larval stages are passed through before the starfish
shape is discernible within this curious “nurse”
or living, changing egg. Then the entire mass,
so elaborately evolved through so long a time, is absorbed
and the little baby star sinks to the bottom to start
on its new life, crawling around and over whatever
happens in its path and feeding to repletion on succulent
oysters. It can laugh at the rage of the oysterman,
who angrily tears it in pieces, for “time heals
all wounds” literally in the case of these creatures,
and even if the five arms are torn apart, five starfish,
small of arm but with healthy stomachs, will soon be
foraging on the oyster bed.
But to return to our tide-pools.
In the skimming net with the young starfish many other
creatures are found, some so delicate and fragile that
they disintegrate before microscope and camera can
be placed in position. I lie at full length on
a soft couch of seaweed with my face close to a tiny
pool no larger than my hand. A few armadillo shells
and limpets crawl on the bottom, but a frequent troubling
of the water baffles me. I make sure my breath
has nothing to do with it, but still it continues.
At last a beam of sunshine lights up the pool, and
as if a film had rolled from my eyes I see the cause
of the disturbance. A sea-worm or a
ghost of one is swimming about. Its
large, brilliant eyes, long tentacles, and innumerable
waving appendages are now as distinct as before they
had been invisible. A trifling change in my position
and all vanishes as if by magic. There seems
not an organ, not a single part of the creature, which
is not as transparent as the water itself. The
fine streamers into which the paddles and gills are
divided are too delicate to have existence in any but
a water creature, and the least attempt to lift the
animal from its element would only tear and dismember
it, so I leave it in the pool to await the return
of the tide.
Shrimps and prawns of many shapes
and colours inhabit every pool. One small species,
abundant on the algae, combines the colour changes
of a chameleon with the form and manner of travel
of a measuring-worm, looping along the fronds of seaweed
or swimming with the same motion. Another variety
of shrimp resembles the common wood-louse found under
pieces of bark, but is most beautifully iridescent,
glowing like an opal at the bottom of the pool.
The curious little sea-spiders keep me guessing for
a long time where their internal organs can be, as
they consist of legs with merely enough body to connect
these firmly together. The fact that the thread-like
stomach and other organs send a branch into each of
the eight legs explains the mystery and shows how
far economy of space may go. Their skeleton-forms,
having the appearance of eight straggling filaments
of seaweed, are thus, doubtless, a great protection
to these creatures from their many enemies. Other
hobgoblin forms with huge probosces crawl slowly over
the floors of the anemone caves, or crouch as the shadow
of my hand or net falls upon them.
The larger gorgeously coloured and
graceful sea-worms contribute not a small share to
the beauty of Fundy tide-pools, swimming in iridescent
waves through the water or waving their Medusa-head
of crimson tentacles at the bottom among the sea-lettuce.
These worms form tubes of mud for themselves, and
the rows of hooks on each side of the body enable them
to climb up and down in their dismal homes.
Much of the seaweed from deeper bottoms
seems to be covered with a dense fur, which under
a hand lens resolves into beautiful hydroids, near
relatives of the anémones and corals.
Scientists have happily given these most euphonious
names Campanularia, Obelia,
and Plumularia. Among the branches of
certain of these, numbers of round discs or spheres
are visible. These are young medusae or jelly-fish,
which grow like bunches of currants, and later will
break off and swim around at pleasure in the water.
Occasionally one is fortunate enough to discover these
small jellies in a pool where they can be photographed
as they pulsate back and forth. When these attain
their full size they lay eggs which sink to the bottom
and grow up into the plant-like hydroids. So each
generation of these interesting creatures is entirely
unlike that which immediately precedes or follows
it. In other words, a hydroid is exactly like
its grandmother and granddaughter, but as different
from its parents and children in appearance as a plant
is from an animal. Even in a fairy-story book
this would be wonderful, but here it is taking place
under our very eyes, as are scores of other transformations
and “miracles in miniature” in this marvellous
underworld.
Now let us deliberately pass by all
the attractions of the middle zone of tide-pools and
on as far as the lowest level of the water will admit.
We are far out from the shore and many feet below
the level of the barnacle-covered boulders over which
we first clambered. Now we may indeed be prepared
for strange sights, for we are on the very borderland
of the vast unknown. The abyss in front of us
is like planetary space, unknown to the feet of man.
While we know the latter by scant glimpses through
our telescopes, the former has only been scratched
by the hauls of the dredge, the mark of whose iron
shoe is like the tiny track of a snail on the leaf
mould of a vast forest.
The first plunge beneath the icy waters
of Fundy is likely to remain long in one’s memory,
and one’s first dive of short duration, but the
glimpse which is had and the hastily snatched handfuls
of specimens of the beauties which no tide ever uncovers
is potent to make one forget his shivering and again
and again seek to penetrate as far as a good-sized
stone and a lungful of air will carry him. Strange
sensations are experienced in these aquatic scrambles.
It takes a long time to get used to pulling oneself
downward, or propping your knees against the
under crevices of rocks. To all intents
and purposes, the law of gravitation is partly suspended,
and when stone and wooden wedge accidentally slip from
one’s hand and disappear in opposite directions,
it is confusing, to say the least.
When working in one spot for some
time the fishes seem to become used to one, and approach
quite closely. Slick-looking pollock, bloated
lump-fish, and occasionally a sombre dog-fish rolls
by, giving one a start, as the memory of pictures
of battles between divers and sharks of tropical waters
comes to mind. One’s mental impressions
made thus are somewhat disconnected. With the
blood buzzing in the ears, it is only possible to
snatch general glimpses and superficial details.
Then at the surface, notes can be made, and specimens
which have been overlooked, felt for during the next
trip beneath the surface. Fronds of laminaria
yards in length, like sheets of rubber, offer convenient
holds, and at their roots many curious creatures make
their home. Serpent starfish, agile as insects
and very brittle, are abundant, and new forms of worms,
like great slugs, their backs covered with
gills in the form of tufted branches.
In these outer, eternally submerged
regions are starfish of still other shapes, some with
a dozen or more arms. I took one with thirteen
rays and placed it temporarily in a pool aquarium
with some large anémones. On returning
in an hour or two I found the starfish trying to make
a meal of the largest anemone. Hundreds of dart-covered
strings had been pushed out by the latter in defence,
but they seemed to cause the starfish no inconvenience
whatever.
In my submarine glimpses I saw spaces
free from seaweed on which hundreds of tall polyps
were growing, some singly, others in small tufts.
The solitary individuals rise three or four inches
by a nearly straight stalk, surmounted by a many-tentacled
head. This droops gracefully to one side and
the general effect is that of a bed of rose-coloured
flowers. From the heads hang grape-like masses,
which on examination in a tumbler are seen to be immature
medusae. Each of these develop to the point where
the four radiating canals are discernible and then
their growth comes to a standstill, and they never
attain the freedom for which their structure fits
them.
When the wind blew inshore, I would
often find the water fairly alive with large sun-jellies
or Aurelia, their Latin name.
Their great milky-white bodies would come heaving
along and bump against me, giving a very “crawly”
sensation. The circle of short tentacles and the
four horse-shoe-shaped ovaries distinguish this jelly-fish
from all others. When I had gone down as far
as I dared, I would sometimes catch glimpses of these
strange beings far below me, passing and repassing
in the silence and icy coldness of the watery depths.
These large medusae are often very abundant after
a favourable wind has blown for a few days, and I have
rowed through masses of them so thick that it seemed
like rowing through thick jelly, two or three feet
deep. In an area the length of the boat and about
a yard wide, I have counted over one hundred and fifty
Aurelias on the surface alone.
When one of these “sunfish,”
as the fishermen call them, is lifted from the water,
the clay-coloured eggs may be seen to stream from it
in myriads. In many jellies, small bodies the
size of a pea are visible in the interior of the mass,
and when extracted they prove to be a species of small
shrimp. These are well adapted for their quasi-parasitic
life, in colour being throughout of the same milky
semi-opaqueness as their host, but one very curious
thing about them is, that when taken out and placed
in some water in a vial or tumbler they begin to turn
darker almost immediately, and in five minutes all
will be of various shades, from red to a dark brown.
I had no fear of Aurelia, but
when another free-swimming species of jelly-fish,
Cyanea, or the blue-jelly, appeared, I swam
ashore with all speed. This great jelly is usually
more of a reddish liver-colour than a purple, and
is much to be dreaded. Its tentacles are of enormous
length. I have seen specimens which measured
two feet across the disc, with streamers fully forty
feet long, and one has been recorded seven feet across
and no less than one hundred and twelve feet to the
tip of the cruel tentacles! These trail behind
in eight bunches and form a living, tangled labyrinth
as deadly as the hair of the fabled Medusa whose
name indeed has been so appropriately applied to this
division of animals. The touch of each tentacle
to the skin is like a lash of nettle, and there would
be little hope for a diver whose path crossed such
a fiery tangle. The untold myriads of little
darts which are shot out secrete a poison which is
terribly irritating.
On the crevice bottoms a sight now
and then meets my eyes which brings the “devil-fish”
of Victor Hugo’s romance vividly to mind, a
misshapen squid making its way snakily over the shells
and seaweed. Its large eyes gaze fixedly around
and the arms reach alternately forward, the sucking
cups lined with their cruel teeth closing over the
inequalities of the bottom. The creature may
suddenly change its mode of progression and shoot like
an arrow, backward and upward. If we watch one
in its passage over areas of seaweed and sand, a wonderful
adaptation becomes apparent. Its colour changes
continually; when near sand it is of a sombre brown
hue, then blushes of colour pass over it and the tint
changes, corresponding to the seaweed or patches of
pink sponge over which it swims. The way in which
this is accomplished is very ingenious and loses nothing
by examination. Beneath the skin are numerous
cells filled with liquid pigment. When at rest
these contract until they are almost invisible, appearing
as very small specks or dots on the surface of the
body. When the animal wishes to change its hue,
certain muscles which radiate from these colour cells
are shortened, drawing the cells out in all directions
until they seem confluent. It is as if the freckles
on a person’s face should be all joined together,
when an ordinary tan would result.
From bottoms ten to twenty fathoms
below the surface, deeper than mortal eye can probably
ever hope to reach, the dredge brings up all manner
of curious things; basket starfish, with arms divided
and subdivided into many tendrils, on the tips of
which it walks, the remaining part converging upward
like the trellis of a vine-covered summer house.
Sponges of many hues must fairly carpet large areas
of the deep water, as the dredge is often loaded with
them. The small shore-loving ones which I photographed
are in perfect health, but the camera cannot show the
many tiny currents of water pouring in food and oxygen
at the smaller openings, and returning in larger streams
from the tall funnels on the surface of the sponge,
which a pinch of carmine dust reveals so beautifully.
From the deeper aquatic gardens come up great orange
and yellow sponges, two and three feet in length,
and around the bases of these the weird serpent stars
are clinging, while crabs scurry away as the mass reaches
the surface of the water.
Treasures from depths of forty and
even fifty fathoms can be obtained when a trip is
taken with the trawl-men. One can sit fascinated
for hours, watching the hundreds of yards of line
reel in, with some interesting creature on each of
the thirty-seven hundred odd hooks. At times a
glance down into the clear water will show a score
of fish in sight at once, hake, haddock, cod, halibut,
dog-fish, and perhaps an immense “barndoor”
skate, a yard or more square. This latter hold
back with frantic flaps of its great “wings,”
and tax all the strength of the sturdy Acadian fishermen
to pull it to the gunwale.
Now and then a huge “meat-rock,”
the fishermen’s apt name for an anemone, comes
up, impaled on a hook, and still clinging to a stone
of five to ten pounds weight. These gigantic
scarlet ones from full fifty fathoms far surpass any
near shore. Occasionally the head alone of a large
fish will appear, with the entire body bitten clean
off, a hint of the monsters which must haunt the lower
depths. The pressure of the air must be excessive,
for many of the fishes have their swimming bladders
fairly forced out of their mouths by the lessening
of atmospheric pressure as they are drawn to the surface.
When a basket starfish finds one of the baits in that
sunless void far beneath our boat, he hugs it so tenaciously
that the upward jerks of the reel only make him hold
the more tightly.
Once in a great while the fishermen
find what they call a “knob-fish” on one
of their hooks, and I never knew what they meant until
one day a small colony of five was brought ashore.
Boltenia, the scientists call them, tall, queer-shaped
things; a stalk six to eight inches in length, with
a knob or oblong bulb-like body at the summit, looking
exactly like the flower of a lady-slipper orchid and
as delicately coloured. This is a member of that
curious family of Ascidians, which forever trembles
in the balance between the higher backboned animals
and the lower division, where are classified the humbler
insects, crabs, and snails. The young of Boltenia
promises everything in its tiny backbone or notochord,
but it all ends in promise, for that shadow of a great
ambition withers away, and the creature is doomed
to a lowly and vegetative life. If we soften the
hard scientific facts which tell us of these dumb,
blind creatures, with the humane mellowing thought
of the oneness of all life, we will find much that
is pathetic and affecting in their humble biographies
from our point of view. And yet these cases of
degeneration are far from anything like actual misfortunes,
or mishaps of nature, as Buffon was so fond of thinking.
These creatures have found their adult mode of life
more free from competition than any other, and hence
their adoption of it. It is only another instance
of exquisite adaptation to an unfilled niche in the
life of the world.
Yet another phase of enjoying the
life of these northern waters; the one which comes
after all the work and play of collecting is over for
the day, after the last specimen is given a fresh
supply of water for the night, and the final note
in our journal is written. Then, as dusk falls,
we make our way to the beach, ship our rudder and
oars and push slowly along shore, or drift quietly
with the tide. The stars may come out in clear
splendour and the visual symphony of the northern lights
play over the dark vault above us, or all may be obscured
in lowering, leaden clouds. But the lights of
the sea are never obscured they always shine
with a splendour which keeps one entranced for hours.
At night the ripples and foam of the
Fundy shores seem transformed to molten silver and
gold, and after each receding wave the emerald seaweed
is left dripping with millions of sparkling lights,
shining with a living lustre which would pale the
brightest gem. Each of these countless sparks
is a tiny animal, as perfect in its substance and as
well adapted to its cycle of life as the highest created
being. The wonderful way in which this phosphorescence
permeates everything the jelly-fish seeming
elfish fireworks as they throb through the water with
rhythmic beats the fish brilliantly lighted
up and plainly visible as they dart about far beneath
the surface makes such a night on the Bay
of Fundy an experience to be always remembered.
Like the tints on
a crescent sea beach
When the moon is new and thin,
Into our hearts high yearnings
Come welling and surging in
Come, from the mystic ocean,
Whose rim no foot has trod
Some of us call it longing,
And others call it God.
W. H. Carruth.
