It was for a long time supposed that these wonderful creatures were extinct, but dredges have brought up from the dark depths of the sea actual living stone lilies, or _crinoids_, this being their real name. Few of us will probably ever have an opportunity of studying a crinoid alive, although in our museums we may see them preserved in gla.s.s jars. That, however, detracts nothing from the marvel of their history and relationship. They send root-like organs deep into the mud, where they coil about some sh.e.l.l and there cling fast. Then the stem grows tall and slender, and upon the summit blooms or is developed the animal-flower. Its nourishment is not drawn from the roots and the air, as is that of the daisy, but is provided by the tiny creatures which swim to its tentacles, or are borne thither by the ocean currents. Some of these crinoids, as if impatient of their plant-like life and a.s.serting their animal kinship, at last tear themselves free from their stem and float off, turn over, and thereafter live happily upon the bottom of the sea, roaming where they will, creeping slowly along and fulfilling the destiny of our imaginary daisy.
And here a comparison comes suddenly to mind. How like to a many-rayed starfish is our creeping crinoid! Few of us, unless we had studies about these creatures, could distinguish between a crinoid and one of the frisky little dancing stars, or serpent stars, which are so common in the rocky caves along our coast. This relationship is no less real than apparent.
The hard-skinned "five finger," or common starfish, which we may pick up on any beach, while it never grew upon a stem, yet still preserves the radial symmetry of its stalked ancestors. Pick up your starfish, carry it to the nearest field, and pluck a daisy close to the head. How interesting the comparison becomes, now that the knowledge of its meaning is plain.
Anything which grows fast upon a single immovable stem tends to grow equally in all directions. We need not stop here, for we may include sea anemones and corals, those most marvellously coloured flowers of the sea, which grow upon a short, thick stalk and send out their tentacles equally in all directions. And many of the jelly-fish which throb along close beneath the surface swells were in their youth each a section of a pile of saucer-like individuals, which were fastened by a single stalk to some sh.e.l.l or piece of coral.
We will remember that it was suggested that the theoretical daisy would soon alter its shape after it entered upon active life. This is plainly seen in the starfish, although at first glance the creature seems as radially symmetrical as a wheel. But at one side of the body, between two of the arms, is a tiny perforated plate, serving to strain the water which enters the body, and thus the circular tendency is broken, and a beginning made toward right and left handedness. In certain sea-urchins, which are really starfishes with the gaps between the arms filled up, the body is elongated, and thus the head and tail conditions of all animals higher in the scale of life are represented.
THE DREAM OF THE YELLOW-THROAT
Many of us look with longing to the days of Columbus; we chafe at the thought of no more continents to discover; no unknown seas to encompa.s.s.
But at our very doors is an "undiscovered bourne," from which, while the traveller invariably returns, yet he will have penetrated but slightly into its mysteries. This unexplored region is night.
When the dusk settles down and the creatures of sunlight seek their rest, a new realm of life awakens into being. The flaring colours and loud bustle of the day fade and are lost, and in their place come soft, gray tones and silence. The scarlet tanager seeks some hidden perch and soon from the same tree slips a silent, ghostly owl; the ruby of the hummingbird dies out as the gaudy flowers of day close their petals, and the gray wraiths of sphinx moths appear and sip nectar from the spectral moonflowers.
With feet shod with silence, let us creep near a dense tangle of sweetbrier and woodbine late some summer evening and listen to the sounds of the night-folk. How few there are that our ears can a.n.a.lyse! We huddle close to the ground and shut our eyes. Then little by little we open them and set our senses of sight and hearing at keenest pitch. Even so, how handicapped are we compared to the wild creatures. A tiny voice becomes audible, then dies away,--entering for a moment the narrow range of our coa.r.s.e hearing,--and finishing its message of invitation or challenge in vibrations too fine for our ears.
Were we crouched by a dense yew hedge, bordering an English country lane, a nightingale might delight us,--a melody of day, softened, adapted, to the night. If the air about us was heavy with the scent of orange blossoms of some covert in our own southland, the glorious harmony of a mockingbird might surge through the gloom,--a.s.suaging the ear as do the blossoms another sense.
But sitting still in our own home tangle let us listen,--listen. Our eyes have slipped the scales of our listless civilised life and pierce the darkness with the acuteness of our primeval forefathers; our ears tingle and strain.
A slender tongue of sound arises from the bush before us. Again and again it comes, m.u.f.fled but increasing in volume. A tiny ball of feathers is perched in the centre of the tangle, with beak hidden in the deep, soft plumage, but ever and anon the little body throbs and the song falls gently on the silence of the night: "I beseech you! I beseech you! I beseech you!" A Maryland yellow-throat is asleep and singing in its dreams.
As we look and listen, a shadowless something hovers overhead, and, looking upward, we see a gray screech owl silently hanging on beating wings. His sharp ears have caught the m.u.f.fled sound; his eyes search out the tangle, but the yellow-throat is out of reach. The little hunter drifts away into the blackness, the song ends and the sharp squeak of a mouse startles us. We rise slowly from our cramped position and quietly leave the mysteries of the night.
SEPTEMBER
THE Pa.s.sING OF THE FLOCKS
It is September. August--the month of gray days for birds--has pa.s.sed. The last pin-feather of the new winter plumage has burst its sheath, and is sleek and glistening from its thorough oiling with waterproof dressing, which the birds squeeze out with their bills from a special gland, and which they rub into every part of their plumage. The youngsters, now grown as large as their parents, have become proficient in fly-catching or berry-picking, as the case may be. Henceforth they forage for themselves, although if we watch carefully we may still see a parent"s love prompting it to give a berry to its big offspring (indistinguishable save for this attention), who greedily devours it without so much as a wing flutter of thanks.
Two courses are open to the young birds who have been so fortunate as to escape the dangers of nestlinghood. They may unite in neighbourly flocks with others of their kind, as do the blackbirds of the marshes; or they may wander off by themselves, never going very far from their summer home, but perching alone each night in the thick foliage of some sheltering bush.
How wonderfully the little fellow adapts himself to the radical and sudden change in his life! Before this, his world has been a warm, soft-lined nest, with ever anxious parents to shelter him from rain and cold, or to stand with half-spread wings between him and the burning rays of the sun.
He has only to open his mouth and call for food and a supply of the choicest morsels appears and is shoved far down his throat. If danger threatens, both parents are ready to fight to the last, or even willing to give their lives to protect him. Little wonder is it that the young birds are loth to leave; we can sympathise heartily with the last weaker brother, whose feet cling convulsively to the nest, who begs piteously for "just one more caterpillar!" But the mother bird is inexorable and stands a little way out of reach with the juiciest morsel she can find. Once out, the young bird never returns. Even if we catch the little chap before he finishes his first flight and replace him, the magic spell of home is broken, and he is out again the instant our hand frees him.
What a change the first night brings! Yet with unfailing instinct he squats on some twig, fluffs up his feathers, tucks his wee head behind his wing, and sleeps the sleep of his first adult birdhood as soundly as if this position of rest had been familiar to him since he broke through the sh.e.l.l.
We admire his apt.i.tude for learning; how quickly his wings gain strength and skill; how soon he manages to catch his own dinner. But how all this pales before the accomplishment of a young brush turkey or moundbuilder of the antipodes. Hatched six or eight feet under ground, merely by the heat of decaying vegetation, no fond parents minister to his wants. Not only must he escape from the sh.e.l.l in the pressure and darkness of his underground prison (how we cannot tell), but he is then compelled to dig through six feet of leaves and mould before he reaches the sunlight. He finds himself well feathered, and at once spreads his small but perfect wings and goes humming off to seek his living alone and unattended.
It is September--the month of restlessness for the birds. Weeks ago the first migrants started on their southward journey, the more delicate insect-eaters going first, before the goldfinches and other late nesters had half finished housekeeping. The northern warblers drift past us southward--the magnolia, blackburnian, Canadian fly-catching, and others, bringing memories of spruce and balsam to those of us who have lived with them in the forests of the north.
"It"s getting too cold for the little fellows," says the wiseacre, who sees you watching the smaller birds as they pa.s.s southward. Is it, though?
What of the tiny winter wren which spends the zero weather with us? His coat is no warmer than those birds which have gone to the far tropics. And what of the flocks of birds which we occasionally come across in mid-winter, of species which generally migrate to Brazil? It is not the cold which deprives us of our summer friends, or at least the great majority of them; it is the decrease in food supply. Insects disappear, and only those birds which feed on seeds and buds, or are able to glean an insect diet from the crevices of fence and tree-trunk, can abide.
This is the month to climb out on the roof of your house, lie on your back and listen. He is a stolid person indeed who is not moved by the chirps and twitters which come down through the darkness. There is no better way to show what a wonderful power sound has upon our memories. There sounds a robin"s note, and spring seems here again; through the night comes a white-throat"s chirp, and we see again the fog-dimmed fields of a Nova Scotian upland; a sandpiper "peets" and the scene in our mind"s eye as instantly changes, and so on. What a revelation if we could see as in daylight for a few moments! The sky would be pitted with thousands and thousands of birds flying from a few hundred yards to as high as one or two miles above the earth.
It only adds to the interest of this phenomenon when we turn to our learned books on birds for an explanation of the origin of migration, the whence and whither of the long journeys by day and night, and find--no certain answer! This is one of the greatest of the many mysteries of the natural world, of which little is known, although much is guessed, and the bright September nights may reveal to us--we know not what undiscovered facts.
I see my way as birds their trackless way.
I shall arrive; what time, what circuit first, I ask not; but unless G.o.d sends his hail Of blinding fire-b.a.l.l.s, sleet or driving snow, In sometime, his good time, I shall arrive; He guides me and the bird. In his good time.
Robert Browning.
GHOSTS OF THE EARTH
We may know the name of every tree near our home; we may recognise each blossom in the field, every weed by the wayside; yet we should be astonished to be told that there are hundreds of plants--many of them of exquisite beauty--which we have overlooked in very sight of our doorstep.
What of the green film which is drawn over every moist tree-trunk or shaded wall, or of the emerald film which coats the water of the pond"s edge? Or the gray lichens painting the rocks and logs, toning down the shingles; the toadstools which, like pale vegetable ghosts, spring up in a night from the turf; or the sombre puff b.a.l.l.s which seem dead from their birth?
The moulds which cover bread and cheese with a delicate tracery of filaments and raise on high their tiny b.a.l.l.s of spores are as worthy to be called a plant growth as are the great oaks which shade our houses. The rusts and mildews and blights which destroy our fruit all have their beauty of growth and fruition when we examine them through a lens, and the yeast by which flour and water is made to rise into the porous, spongy dough is just as truly a plant as is the geranium blossoming at the kitchen window.
If we wonder at the fierce struggle for existence which allows only a few out of the many seeds of a maple or thistle to germinate and grow up, how can we realise the obstacles with which these lowly plants have to contend? A weed in the garden may produce from one to ten thousand seeds, and one of our rarest ferns scatters in a single season over fifty millions spores; while from the larger puff-b.a.l.l.s come clouds of unnumbered millions of spores, blowing to the ends of the earth; yet we may search for days without finding one full-grown individual.
All the a.s.semblage of mushrooms and toadstools,--although the most deadly may flaunt bright hues of scarlet and yellow,--yet lack the healthy green of ordinary plants. This is due to the fact that they have become brown parasites or scavengers, and instead of trans.m.u.ting heat and moisture and the salts of the earth into tissue by means of the pleasant-hued chlorophyll, these sylvan ghosts subsist upon the sap of roots or the tissues of decaying wood. Emanc.i.p.ated from the normal life of the higher plants, even flowers have been denied them and their fruit is but a cloud of brown dust,--each mote a simple cell.
But what of the delicate Indian pipe which gleams out from the darkest aisles of the forest? If we lift up its hanging head we will find a perfect flower, and its secret is discovered. Traitor to its kind, it has dropped from the ranks of the laurels, the heather, and the jolly little wintergreens to the colourless life of a parasite,--hobn.o.bbing with clammy toadstools and slimy lichens. Its common names are all appropriate,--ice-plant, ghost-flower, corpse-plant.
Nevertheless it is a delicately beautiful creation, and we have no right to apply our human standards of ethics to these children of the wild, whose only chance of life is to seize every opportunity,--to make use of each hint of easier existence.
We have excellent descriptions and cla.s.sifications of mushrooms and toadstools, but of the actual life of these organisms, of the conditions of their growth, little is known. Some of the most hideous are delicious to our palate, some of the most beautiful are certain death. The splendid red and yellow amanita, which lights up a dark spot in the woods like some flowering orchid, is a veritable trap of death. Though human beings have learned the fatal lesson and leave it alone, the poor flies in the woods are ever deceived by its brightness, or odour, and a circle of their bodies upon the ground shows the result of their ignorance.
MUSKRATS
Long before man began to inherit the earth, giant beavers built their dams and swam in the streams of long ago. For ages these creatures have been extinct. Our forefathers, during historical times, found smaller beavers abundant, and with such zeal did they trap them that this modern race is now well-nigh vanished. Nothing is left to us but the humble muskrat,--which in name and in facile adaptation to the encroachments of civilization has little in common with his more n.o.ble predecessor. Yet in many ways his habits of life bring to mind the beaver.
Let us make the most of our heritage and watch at the edge of a stream some evening in late fall. If the muskrats have half finished their mound of sticks and mud, which is to serve them for a winter home, we will be sure to see some of them at work. Two lines of ripples furrow the surface outward from the farther bank, and a small dark form clambers upon the pile of rubbish. Suddenly a _spat!_ sounds at our very feet, and a muskrat dives headlong into the water, followed by the one on the ground. Another _spat!_ and splash comes from farther down the stream, and so the danger signal of the muskrat clan is pa.s.sed along,--a single flap upon the water with the flat of the tail.
