A most admirable servant of mine once risked his life to reach a magnificent Bornean orchid, and tried to poison me an hour later when he thought I was going to take the plant away from him. This does not mean necessarily that we should look with suspicion upon all gardeners and lovers of flowers. It emphasizes, rather, the fact of the universal and deep-rooted appreciation of the glories of the vegetable kingdom. Long before the fatal harvest time, I am certain that Eve must have plucked a spray of apple blossoms with perfect impunity.
A vast amount of bad poetry and a much less quantity of excellent verse has been written about flowers, much of which follows to the letter Mark Twain's injunction about Truth. It must be admitted that the relations existing between the honeysuckle and the bee are basely practical and wholly selfish. A butterfly's admiration of a flower is no whit less than the blossom's consciousappreciation of its own beauties. There are ants which spend most of their life making gardens, knowing the uses of fertilizers, mulching, planting seeds, exercising patience, recognizing the time of ripeness, and gathering the edible fruit. But this is underground, and the ants are blind.
There is a bird, however—the bower bird of Australia—which appears to take real delight in bright things, especially pebbles and flowers for their own sake. Its little lean-to, or bower of sticks, which has been built in our own Zoological Park in New York City, is fronted by a cleared space, which is usually mossy. To this it brings its colorful treasures, sometimes a score of bright star blossoms, which are renewed when faded and replaced by others. All this has, probably, something to do with courtship, which should inspire a sonnet.
From the first pre-Egyptian who crudely scratched a lotus on his dish of clay, down to the jolly Feckenham men, the human race has given to flowers something more than idle curiosity, something less than mere earnest of fruit or berry.
At twelve thousand feet I have seen one of my Tibetans with nothing but a few shreds ofstraw between his bare feet and the snow, probe around the south edge of melting drifts until he found brilliant little primroses to stick behind his ears. I have been ushered into the little-used, musty best-parlor of a New England farmhouse, and seen fresh vases of homely, old-fashioned flowers—so recently placed for my edification, that drops of water still glistened like dewdrops on the dusty plush mat beneath. I have sat in the seat of honor of a Dyak communal house, looked up at the circle of all too recent heads, and seen a gay flower in each hollow eye socket, placed there for my approval. With a cluster of colored petals swaying in the breeze, one may at times bridge centuries or span the earth.
And now as I sit writing these words in my jungle laboratory, a small dusky hand steals around an aquarium and deposits a beautiful spray of orchids on my table. The little face appears, and I can distinguish the high cheek bones of Indian blood, the flattened nose and slight kink of negro, and the faint trace of white—probably of some long forgotten Dutch sailor, who came and went to Guiana, while New York City was still a browsing ground for moose.
So neither race nor age nor mélange of bloodcan eradicate the love of flowers. It would be a wonderful thing to know about the first garden that ever was, and I wish that "Best Beloved" had demanded this. I am sure it was long before the day of dog, or cow, or horse, or even she who walked alone. The only way we can imagine it, is to go to some wild part of the earth, where are fortunate people who have never heard of seed catalogs or lawn mowers.
Here in British Guiana I can run the whole gamut of gardens, within a few miles of where I am writing. A mile above my laboratory up-river, is the thatchedbenabof an Akawai Indian—whose house is a roof, whose rooms are hammocks, whose estate is the jungle. Degas can speak English, and knows the use of my 28-gauge double barrel well enough to bring us a constant supply of delicious bushmeat—peccary, deer, monkey, bush turkeys and agoutis. But Grandmother has no language but her native Akawai. She is a good friend of mine, and we hold long conversations, neither of us bothering with the letter, but only the spirit of communication. She is a tiny person, bowed and wrinkled as only an old Indian squaw can be, always jolly and chuckling to herself, althoughDegas tells me that the world is gradually darkening for her. And she vainly begs me to clear the film which is slowly closing over her eyes. She labors in a true landscape garden—the small circle wrested with cutlass and fire from the great jungle, and kept free only by constant cutting of the vines and lianas which creep out almost in a night, like sinister octopus tentacles, to strangle the strange upstarts and rejungle the bit of sunlit glade.
Although to the eye a mass of tangled vegetation, an Indian's garden may be resolved into several phases—all utterly practical, with color and flowers as mere by-products. First come the provisions, for if Degas were not hunting for me, and eating my rations, he would be out with bow and blowpipe, or fish-hooks, while the women worked all day in the cassava field. It is his part to clear and burn the forest, it is hers to grub up the rich mold, to plant and to weed. Plots and beds are unknown, for in every direction are fallen trees, too large to burn or be chopped up, and great sprawling roots. Between these, sprouts of cassava and banana are stuck, and the yams and melons which form the food of these primitive people. Cassava is as vital to theseIndians as the air they breathe. It is their wheat and corn and rice, their soup and salad and dessert, their ice and their wine, for besides being their staple food, it providescasareepwhich preserves their meat, andpiwariewhich, like excellent wine, brightens life for them occasionally, or dims it if overindulged in—which is equally true of food, or companionship, or the oxygen in the air we breathe.
Besides this cultivation, Grandmother has a small group of plants which are only indirectly concerned with food. One iskunami, whose leaves are pounded into pulp, and used for poisoning the water of jungle streams, with the surprising result that the fish all leap out on the bank and can be gathered as one picks up nuts. When I first visited Grandmother's garden, she had a few pitiful little cotton plants from whose stunted bolls she extracted every fiber and made a most excellent thread. In fact, when she made some bead aprons for me, she rejected my spool of cotton and chose her own, twisted between thumb and finger. I sent for seed of the big Sea Island cotton, and her face almost unwrinkled with delight when she saw the packets with seed larger than she had ever known.
Far off in one corner I make certain I have found beauty for beauty's sake, a group of exquisite caladiums and amaryllis, beautiful flowers and rich green leaves with spots and slashes of white and crimson. But this is the hunter's garden, and Grandmother has no part in it, perhaps is not even allowed to approach it. It is thebeenagarden—the charms for good luck in hunting. The similarity of the leaves to the head or other parts of deer or peccary or red-gilled fish, decides the most favorable choice, and the acrid, smarting juice of the tuber rubbed into the skin, or the hooks and arrows anointed, is considered sufficient to produce the desired result. Long ago I discovered that this demand for immediate physical sensation was a necessary corollary of doctoring, so I always give two medicines—one for its curative properties, and the other, bitter, sour, acid or anything disagreeable, for arousing and sustaining faith in my ability.
The Indian's medicine plants, like his true name, he keeps to himself, and although I feel certain that Grandmother had somewhere a toothache bush, or pain leaves—yarbs and simples for various miseries—I could never discover them. Half a dozen tall tobacco plants broughtfrom the far interior, eked out the occasional tins of cigarettes in which Degas indulged, and always the flame-colored little buck-peppers lightened up the shadows of thebenab, as hot to the palate as their color to the eye.
One day just as I was leaving, Grandmother led me to a palm nearby, and to one of its ancient frond-sheaths was fastened a small brown branch to which a few blue-green leaves were attached. I had never seen anything like it. She mumbled and touched it with her shriveled, bent fingers. I could understand nothing, and sent for Degas, who came and explained grudgingly, "Me no know what for—toko-nookjust name—have got smell when yellow." And so at last I found the bit of uselessness, which, carried onward and developed in ages to come, as it had been elsewhere in ages past, was to evolve into botany, and back-yard gardens, and greenhouses, and wars of roses, and beautiful paintings, and music with a soul of its own, and verse more than human. To Degas thetoko-nookwas "just name," "and it was nothing more." But he was forgiven, for he had all unwittingly sowed the seeds of religion, through faith in his glowing caladiums. But Grandmother, though all thesunlight seemed dusk, and the dawn but as night, yet clung to her little plant, whose glory was that it was of no use whatsoever, but in months to come would be yellow, and would smell.
Farther down river, in the small hamlets of the bovianders—the people of mixed blood—the practical was still necessity, but almost every thatched and wattled hut had its swinging orchid branch, and perhaps a hideous painted tub with picketed rim, in which grew a golden splash of croton. This ostentatious floweritis might furnish a theme for a wholly new phase of the subject—for in almost every respect these people are less worthy human beings—physically, mentally and morally—than the Indians. But one cannot shift literary overalls for philosophical paragraphs in mid-article, so let us take the little river steamer down stream for forty miles to the coast of British Guiana, and there see what Nature herself does in the way of gardens. We drive twenty miles or more before we reach Georgetown, and the sides of the road are lined for most of the distance with huts and hovels of East Indian coolies and native Guiana negroes. Some are made of boxes, others of bark, more of thatch or rough-hewn boards and barrel staves,and some of split bamboo. But they resemble one another in several respects—all are ramshackle, all lean with the grace of Pisa, all have shutters and doors, so that at night they may be hermetically closed, and all are half-hidden in the folds of a curtain of flowers. The most shiftless, unlovely hovel, poised ready to return to its original chemical elements, is embowered in a mosaic of color, which in a northern garden would be worth a king's ransom—or to be strictly modern, should I not say a labor foreman's or a comrade's ransom!
The deep trench which extends along the front of these sad dwellings is sometimes blue with water hyacinths; next the water disappears beneath a maze of tall stalks, topped with a pink mist of lotus; then come floating lilies and more hyacinths. Wherever there is sufficient clear water, the wonderful curve of a cocoanut palm is etched upon it, reflection meeting palm, to form a dendritic pattern unequaled in human devising.
Over a hut of rusty oil-cans, bougainvillia stretches its glowing branches, sometimes cerise, sometimes purple, or allamanders fill the air with a golden haze from their glowing search-lights, either hiding the huts altogether, or softeningtheir details into picturesque ruins. I remember one coolie dwelling which was dirtier and less habitable than the meanest stable, and all around it were hundreds upon hundreds of frangipanni blooms—the white and gold temple flowers of the East—giving forth of scent and color all that a flower is capable, to alleviate the miserable blot of human construction. Now and then a flamboyant tree comes into view, and as, at night, the head-lights of an approaching car eclipse all else, so this tree of burning scarlet draws eye and mind from adjacent human-made squalor. In all the tropics of the world I scarcely remember to have seen more magnificent color than in these unattended, wilful-grown gardens.
In tropical cities such as Georgetown, there are very beautiful private gardens, and the public one is second only to that of Java. But for the most part one is as conscious of the very dreadful borders of brick, or bottles, or conchs, as of the flowers themselves. Some one who is a master gardener will some day write of the possibilities of a tropical garden, which will hold the reader as does desire to behold the gardens of Carcassonne itself.
Again the Guiana jungle comes wonderfully to the eye and mysteriously to the mind; again my khakis and sneakers are skin-comfortable; again I am squatted on a pleasant mat of leaves in a miniature gorge, miles back of my Kartabo bungalow. Life elsewhere has already become unthinkable. I recall a place boiling with worried people, rent with unpleasing sounds, and beset with unsatisfactory pleasures. In less than a year I shall long for a sight of these worried people, my ears will strain to catch the unpleasing sounds, and I shall plunge with joy into the unsatisfactory pleasures. To-day, however, all these have passed from mind, and I settle down another notch, head snuggled on knees, and sway, elephant-fashion, with sheer joy, as a musky, exciting odor comes drifting, apparently by its own volition, down through the windless little gorge.
If I permit a concrete, scientific reaction, Imust acknowledge the source to be a passing bug,—a giant bug,—related distantly to our malodorous northern squash-bug, but emitting a scent as different as orchids' breath from grocery garlic. But I accept this delicate volatility as simply another pastel-soft sense-impression—as an earnest of the worthy, smelly things of old jungles. There is no breeze, no slightest shift of air-particles; yet down the gorge comes this cloud,—a cloud unsensible except to nostrils,—eddying as if swirling around the edges of leaves, riding on the air as gently as the low, distant crooning of great, sleepy jungle doves.
With two senses so perfectly occupied, sight becomes superfluous and I close my eyes. And straightway the scent and the murmur usurp my whole mind with a vivid memory. I am still squatting, but in a dark, fragrant room; and the murmur is still of doves; but the room is in the cool, still heart of the Queen's Golden Monastery in northern Burma, within storm-sound of Tibet, and the doves are perched among the glitter and tinkling bells of the pagoda roofs. I am squatting very quietly, for I am tired, after photographing carved peacocks and junglefowl in the marvelous fretwork of the outer balconies,There are idols all about me—or so it would appear to a missionary; for my part, I can think only of the wonderful face of the old Lama who sits near me, a face peaceful with the something for which most of us would desert what we are doing, if by that we could attain it. Near him are two young priests, sitting as motionless as the Buddha in front of them.
After a half-hour of the strange thing that we call time, the Lama speaks, very low and very; softly:
"The surface of the mirror is clouded with a breath."
Out of a long silence one of the neophytes replies, "The mirror can be wiped clear."
Again the world becomes incense and doves,—in the silence and peace of that monastery, it may have been a few minutes or a decade,—and the second Tibetan whispers, "There is no need to wipe the mirror."
When I have left behind the world of inharmonious colors, of polluted waters, of soot-stained walls and smoke-tinged air, the green of jungle comes like a cooling bath of delicate tints and shades. I think of all the green things I have loved—of malachite in matrix and table-top; ofjade, not factory-hewn baubles, but age-mellowed signets, fashioned by lovers of their craft, and seasoned by the toying yellow fingers of generations of forgotten Chinese emperors—jade, as Dunsany would say, of the exact shade of the right color. I think too, of dainty emerald scarves that are seen and lost in a flash at a dance; of the air-cooled, living green of curling breakers; of a lonely light that gleams to starboard of an unknown passing vessel, and of the transparent green of northern lights that flicker and play on winter nights high over the garish glare of Broadway.
Now, in late afternoon, when I opened my eyes in the little gorge, the soft green vibrations merged insensibly with the longer waves of the doves' voices and with the dying odor. Soon the green alone was dominant; and when I had finished thinking of pleasant, far-off green things, the wonderful emerald of my great tree-frog of last year came to mind,—Gawain the mysterious,—and I wondered if I should ever solve his life.
In front of me was a little jungle rainpool. At the base of the miniature precipice of the gorge, this pool was a thing of clay. It was milky in consistence, from the roiling ofsuspended clay; and when the surface caught a glint of light and reflected it, only the clay and mud walls about came to the eye. It was a very regular pool, a man's height in diameter, and, for all I knew, from two inches to two miles deep. I became absorbed in a sort of subaquatic mirage, in which I seemed to distinguish reflections beneath the surface. My eyes refocused with a jerk, and I realized that something had unconsciously been perceived by my rods and cones, and short-circuited to my duller brain. Where a moment before was an unbroken translucent surface, were now thirteen strange beings who had appeared from the depths, and were mumbling oxygen with trembling lips.
In days to come, through all the months, I should again and again be surprised and cheated and puzzled—all phases of delight in the beings who share the earth's life with me. This was one of the first of the year, and I stiffened into one large eye.
I did not know whether they were fish, fairy shrimps, or frogs; I had never seen anything like them, and they were wholly unexpected. I so much desired to know what they were, that I sat quietly—as I enjoy keeping a treasured letterto the last, or reserving the frosting until the cake is eaten. It occurred to me that, had it not been for the Kaiser, I might have been forbidden this mystery; a chain of occurrences: Kaiser—war—submarines—glass-shortage for dreadnoughts—mica port-holes needed—Guiana prospector—abandoned pits—rainy season—mysterious tenants—me!
When I squatted by the side of the pool, no sign of life was visible. Far up through the green foliage of the jungle I could see a solid ceiling of cloud, while beneath me the liquid clay of the pool was equally opaque and lifeless. As a seer watches the surface of his crystal ball, so I gazed at my six-foot circle of milky water. My shift forward was like the fall of a tree: it brought into existence about it a temporary circle of silence and fear—a circle whose periphery began at once to contract; and after a few minutes the gorge again accepted me as a part of its harmless self. A huge bee zoomed past, and just behind my head a hummingbird beat the air into a froth of sound, as vibrant as the richest tones of a cello. My concentrated interest seemed to become known to the life of the surrounding glade, and I was bombarded with sight,sound, and odor, as if on purpose to distract my attention. But I remained unmoved, and indications of rare and desirable beings passed unheeded.
A flotilla of little water-striders came rowing themselves along, racing for a struggling ant which had fallen into the milky quicksand. These were in my line of vision, so I watched them for a while, letting the corner of my eye keep guard for the real aristocrats of the milky sea—whoever they were. My eye was close enough, my elevation sufficiently low to become one with the water-striders, and to become excited over the adventures of these little petrels; and in my absorption I almost forgot my chief quest. As soaring birds seem at times to rest against the very substance of cloud, as if upheld by some thin lift of air, so these insects glided as easily and skimmed as swiftly upon the surface film of water. I did not know even the genus of this tropical form; but insect taxonomists have been particularly happy in their given names—I recalledHydrobates,Aquarius, andremigis.
The spur-winged jacanas are very skilful in their dainty treading of water-lily leaves; buthere were good-sized insects rowing about on the water itself. They supported themselves on the four hinder legs, rowing with the middle pair, and steering with the hinder ones, while the front limbs were held aloft ready for the seizing of prey. I watched three of them approach the ant, which was struggling to reach the shore, and the first to reach it hesitated not a moment, but leaped into the air from a take-off of mere aqueous surface film, landed full upon the drowning unfortunate, grasped it, and at the same instant gave a mighty sweep with its oars, to escape from its pursuing, envious companions. Off went the twelve dimples, marking the aquatic footprints of the trio of striders; and as the bearer of the ant dodged one of its own kind, it was suddenly threatened by a small, jet submarine of a diving beetle. At the very moment when the pursuit was hottest, and it seemed anybody's ant, I looked aside, and the little water-bugs passed from my sight forever—for scattered over the surface were seven strange, mumbling mouths. Close as I was, their nature still eluded me. At my slightest movement all vanished, not with the virile splash of a fish or the healthy roll and dip of a porpoise, but with a weird, vertical withdrawing—the seven dissolving into the milk to join their six fellows.
This was sufficient to banish further meditative surmising, and I crept swiftly to a point of vantage, and with sweep-net awaited their reappearance. It was five minutes before faint, discolored spots indicated their rising, and at least two minutes more before they actually disturbed the surface. With eight or nine in view, I dipped quickly and got nothing. Then I sank my net deeply and waited again. This time ten minutes passed, and then I swept deep and swiftly, and drew up the net with four flopping, struggling super-tadpoles. They struggled for only a moment, and then lay quietly waiting for what might be sent by the guardian of the fate of tadpoles—surely some quaint little god-relation of Neptune, Pan, and St. Vitus. Gently shunted into a glass jar, these surprising tads accepted the new environment with quiet philosophy; and when I reached the laboratory and transferred them again, they dignifiedly righted themselves in the swirling current, and hung in mid-aquarium, waiting—forever waiting.
It was difficult to think of them as tadpoles, when the word brought to mind hosts of littleblack wrigglers filling puddles and swamps of our northern country. These were slow-moving, graceful creatures, partly transparent, partly reflecting every hue of the spectrum, with broad, waving scarlet and hyaline fins, and strange, fish-like mouths and eyes. Their habits were as unpollywoglike as their appearance. I visited their micaceous pool again and again; and if I could have spent days instead of hours with them, no moment of ennui would have intervened.
My acquaintanceship with tadpoles in the past had not aroused me to enthusiasm in the matter of their mental ability; as, for example, the inmates of the next aquarium to that of the Redfins, where I kept a herd or brood or school of Short-tailed Blacks—pollywogs of the Giant Toad (Bufo marinus). At earliest dawn they swam aimlessly about and mumbled; at high noon they mumbled and still swam; at midnight they refused to be otherwise occupied. It was possible to alarm them; but even while they fled they mumbled.
In bodily form my Redfins were fish, but mentally they had advanced a little beyond the usual tadpole train of reactions, reaching forward toward the varied activities of the future amphibian.One noticeable thing was their segregation, whether in the mica pools, or in two other smaller ones near by, in which I found them. Each held a pure culture of Redfins, and I found that this was no accident, but aided and enforced by the tads themselves. Twice, while I watched them, I saw definite pursuit of an alien pollywog,—the larva of the Scarlet-thighed Leaf-walker (Phyllobates inguinalis),—which fled headlong. The second time the attack was so persistent that the lesser tadpole leaped from the water, wriggled its way to a damp heap of leaves, and slipped down between them. For tadpoles to take such action as this was as reasonable as for an orchid to push a fellow blossom aside on the approach of a fertilizing hawk-moth. This momentary co-operation, and the concerted elimination of the undesired tadpole, affected me as the thought of the first consciousness of power of synchronous rhythm coming to ape men: it seemed a spark of tadpole genius—an adumbration of possibilities which now would end in the dull consciousness of the future frog, but which might, in past ages, have been a vital link in the development of an ancestral Ereops.
My Redfins were assuredly no common tadpoles,and an intolerant pollywog offers worthy research for the naturalist. Straining their medium of its opacity, I drew off the clayey liquid and replaced it with the clearer brown, wallaba-stained water of the Mazaruni; and thereafter all their doings, all their intimacies, were at my mercy. I felt as must have felt the first aviator who flew unheralded over an oriental city, with its patios and house-roofs spread naked beneath him.
It was on one of the early days of observation that an astounding thought came to me—before I had lost perspective in intensive watching, before familiarity had assuaged some of the marvel of these super-tadpoles. Most of those in my jar were of a like size, just short of an inch; but one was much larger, and correspondingly gorgeous in color and graceful in movement. As she swept slowly past my line of vision, she turned and looked, first at me, then up at the limits of her world, with a slow deliberateness and a hint of expression which struck deep into my memory. Green came to mind,—something clad in a smock of emerald, with a waist-coat of mother-of-pearl, and great sprawling arms,—and I found myself thinking of Gawain, our mystery frog of a yearago, who came without warning, and withheld all the secrets of his life. And I glanced again at this super-tad,—as unlike her ultimate development as the grub is unlike the beetle,—and one of us exclaimed, "It is the same, or nearly, but more delicate, more beautiful; it must be Guinevere." And so, probably for the first time in the world, there came to be a pet tadpole, one with an absurd name which will forever be more significant to us than the term applied by a forgotten herpetologist many years ago.
And Guinevere became known to all who had to do with the laboratory. Her health and daily development and color-change were things to be inquired after and discussed; one of us watched her closely and made notes of her life, one painted every radical development of color and pattern, another photographed her, and another brought her delectable scum. She was waited upon as sedulously as a termite queen. And she rewarded us by living, which was all we asked.
It is difficult for a diver to express his emotions on paper, and verbal arguments with a dentist are usually one-sided. So must the spirit of a tadpole suffer greatly from handicaps of the flesh. A mumbling mouth and an uncontrollable,flagellating tail, connected by a pinwheel of intestine, are scant material wherewith to attempt new experiments, whereon to nourish aspirations. Yet the Redfins, as typified by Guinevere, have done both, and given time enough, they may emulate or surpass the achievements of larval axolotls, or the astounding egg-producing maggots of certain gnats, thus realizing all the possibilities of froghood while yet cribbed within the lowly casing of a pollywog.
In the first place Guinevere had ceased being positively thigmotactic, and, writing as a technical herpetologist, I need add no more. In fact, all my readers, whether Batrachologists or Casuals, will agree that this is an unheard-of achievement. But before I loosen the technical etymology and become casually more explicit, let me hold this term in suspense a moment, as I once did, fascinated by the sheer sound of the syllables, as they first came to my ears years ago in a university lecture. There is that of possibility in being positively thigmotactic which makes one dread the necessity of exposing and limiting its meaning, of digging down to its mathematically accurate roots. It could never be called a flower of speech: it is an over-ripe fruit rather:heavy-stoned, thin-fleshed—an essentially practical term. It is eminently suited to its purpose, and so widely used that my friend the editor must accept it; not looking askance as he did at my definition of a vampire as a vespertilial anæsthetist, or breaking into open but wholly ineffectual rebellion, at the past tense of the verb to candelabra. I admit that the conjugation
I candelabraYou candelabraHe candelabras
I candelabraYou candelabraHe candelabras
arouses a ripple of confusion in the mind; but it is far more important to use words than to parse them, anyway, so I acclaim perfect clarity for "The fireflies candelabraed the trees!"
Not to know the precise meaning of being positively thigmotactic is a stimulant to the imagination, which opens the way to an entire essay on the disadvantages of education—a thought once strongly aroused by the glorious red-and-gold hieroglyphic signs of the Peking merchants—signs which have always thrilled me more than the utmost efforts of our modern psychological advertisers.
Having crossed unconsciously by such a slenderetymological bridge from my jungle tadpole to China, it occurs to me that the Chinese are the most positively thigmotactic people in the world. I have walked through block after block of subterranean catacombs, beneath city streets which were literally packed full of humanity, and I have seen hot mud pondlets along the Min River wholly eclipsed by shivering Chinamen packed sardinewise, twenty or thirty in layers, or radiating like the spokes of a great wheel which has fallen into the mud.
From my brood of Short-tailed Blacks, a half-dozen tadpoles wandered off now and then, each scum-mumbling by himself. Shortly his positivism asserted itself and back he wriggled, twisting in and out of the mass of his fellows, or at the approach of danger nuzzling into the dead leaves at the bottom, content only with the feeling of something pressing against his sides and tail. His physical make-up, simple as it is, has proved perfectly adapted to this touch system of life: flat-bottomed, with rather narrow, paddle-shaped tail-fins which, beginning well back of the body, interfere in no way with the pollywog's instincts, he can thigmotact to his heart's content. His eyes are also adapted to looking upward, discerningdimly dangers from above, and whatever else catches the attention of a bottom-loving pollywog. His mouth is well below, as best suits bottom mumbling.
Compared with thesepolloipollywogs, Redfins were as hummingbirds to quail. Their very origin was unique; for while the toad tadpoles wriggled their way free from egg gelatine deposited in the water itself, the Redfins were literally rained down. Within a folded leaf the parents left the eggs—a leaf carefully chosen as overhanging a suitable ditch, or pit, or puddle. If all signs of weather and season failed and a sudden drought set in, sap would dry, leaf would shrivel, and the pitiful gamble for life of the little jungle frogs would be lost; the spoonful of froth would collapse bubble by bubble, and, finally, a thin dry film on the brown leaf would in turn vanish, and Guinevere and her companions would never have been.
But untold centuries of unconscious necessity have made these tree-frogs infallible weather prophets, and the liberating rain soon sifted through the jungle foliage. In the streaming drops which funneled from the curled leaf, tadpole after tadpole hurtled downward andsplashed headlong into the water; their parents and the rain and gravitation had performed their part, and from now on fate lay with the super-tads themselves—except when a passing naturalist brought new complications, new demands of Karma, as strange and unpredictable as if from another planet or universe.
Only close examination showed that these were tadpoles, not fish, judged by the staring eyes, and broad fins stained above and below with orange-scarlet—colors doomed to oblivion in the native, milky waters, but glowing brilliantly in my aquarium. Although they were provided with such an expanse of fin, the only part used for ordinary progression was the extreme tip, a mere threadlike streamer, which whipped in never-ending spirals, lashing forward, backward, and sideways. So rapid was this motion, and so short the flagellum, that the tadpole did not even tremble or vibrate as it moved, but forged steadily onward, without a tremor.
The head was buffy yellow, changing to bittersweet orange back of the eyes and on the gills. The body was dotted with a host of minute specks of gold and silver. On the sides and below, this gave place to a rich bronze, and then to a clear,iridescent silvery blue. The eye proper was silvery white, but the upper part of the eyeball fairly glowed with color. In front it was jet black flecked with gold, merging behind into a brilliant blue. Yet this patch of jeweled tissue was visible only rarely as the tadpole turned forward, and in the opaque liquid of the mica pool must have ever been hidden. And even if plainly seen, of what use was a shred of rainbow to a sexless tadpole in the depths of a shady pool!
With high-arched fins, beginning at neck and throat, body compressed as in a racing yacht, there could be no bottom life for Guinevere. Whenever she touched a horizontal surface,—whether leaf or twig,—she careened; when she sculled through a narrow passage in the floating algæ, her fins bent and rippled as they were pressed bodywards. So she and her fellow brood lived in mid-aquarium, or at most rested lightly against stem or glass, suspended by gentle suction of the complex mouth. Once, when I inserted a long streamer of delicate water-weed, it remained upright, like some strange tree of carboniferous memory. After an hour I found this the perching-place of fourteen Redfin tads, and at the very summit was Guinevere. The restwere arranged nearly in altitudinal size—two large tadpoles being close below Guinevere, and a bevy of six tiny chaps lowest down. All were lightly poised, swaying in mid-water, at a gently sloping angle, like some unheard-of, orange-stained, aquatic autumn foliage.
For two weeks Guinevere remained almost as I have described her, gaining slightly in size, but with little alteration of color or pattern. Then came the time of the great change: we felt it to be imminent before any outward signs indicated its approach. And for four more days there was no hint except the sudden growth of the hind legs. From tiny dangling appendages with minute toes and indefinite knees, they enlarged and bent, and became miniature but perfect frog's limbs.
She had now reached a length of two inches, and her delicate colors and waving fins made her daily more marvelous. The strange thing about the hind limbs was that, although so large and perfect, they were quite useless. They could not even be unflexed; and other mere pollywogs near by were wriggling toes, calves, and thighs while yet these were but imperfect buds. When she dived suddenly, the toes occasionally moved alittle; but as a whole, they merely sagged and drifted like some extraneous things entangled in the body.
Smoothly and gracefully Guinevere moved about the aquarium. Her gills lifted and closed rhythmically—twice as slowly as compared with the three or four times every second of her breathless young tadpolehood. Several times on the fourteenth day, she came quietly to the surface for a gulp of air.
Looking at her from above, two little bulges were visible on either side of the body—the ensheathed elbows pressing outward. Twice, when she lurched forward in alarm, I saw these front limbs jerk spasmodically; and when she was resting quietly, they rubbed and pushed impatiently against their mittened tissue.
And now began a restless shifting, a slow, strange dance in mid-water, wholly unlike any movement of her smaller companions; up and down, slowly revolving on oblique planes, with rhythmical turns and sinkings—this continued for an hour, when I was called for lunch. And as if to punish me for this material digression and desertion, when I returned, in half an hour, the miracle had happened.
Guinevere still danced in stately cadence, with the other Redfins at a distance going about their several businesses. She danced alone—a dance of change, of happenings of tremendous import, of symbolism as majestic as it was age-old. Here in this little glass aquarium the tadpole Guinevere had just freed her arms—she, with waving scarlet fins, watching me with lidless white and staring eyes, still with fish-like, fin-bound body. She danced upright, with new-born arms folded across her breast, tail-tip flagellating frenziedly, stretching long fingers with disks like cymbals, reaching out for the land she had never trod, limbs flexed for leaps she had never made.
A few days before and Guinevere had been a fish, then a helpless biped, and now suddenly, somewhere between my salad and coffee, she became an aquatic quadruped. Strangest of all, her hands were mobile, her feet useless; and when the dance was at an end, and she sank slowly to the bottom, she came to rest on the very tips of her two longest fingers; her legs and toes still drifting high and useless. Just before she ceased, her arms stretched out right froggily, her weird eyes rolled about, and she gulped amighty gulp of the strange thin medium that covered the surface of her liquid home.
At midnight of this same day only three things existed in the world—on my table I turned from theBhagavad-Gitato Drinkwater'sReverieand back again; then I looked up to the jar of clear water and watched Guinevere hovering motionless. At six the next morning she was crouched safely on a bit of paper a foot from the aquarium. She had missed the open window, the four-foot drop to the floor, and a neighboring aquarium stocked with voracious fish: surely the gods of pollywogs were kind to me. The great fins were gone—dissolved into blobs of dull pink; the tail was a mere stub, the feet drawn close, and a glance at her head showed that Guinevere had become a frog almost within an hour. Three things I hastened to observe: the pupils of her eyes were vertical, revealing her genusPhyllomedusa(making apt our choice of the feminine); by a gentle urging I saw that the first and second toes were equal in length; and a glance at her little humped back showed a scattering of white calcareous spots, giving the clue to her specific personality—bicolor: thus were we introduced toPhyllomedusa bicolor, alias Guinevere,and thus was established beyond doubt her close relationship to Gawain.
During that first day, within three hours, during most of which I watched her closely, Guinevere's change in color was beyond belief. For an hour she leaped from time to time; but after that, and for the rest of her life, she crept in strange unfroglike fashion, raised high on all four limbs, with her stubby tail curled upward, and reaching out one weird limb after another. If one's hand approached within a foot, she saw it and stretched forth appealing, skinny fingers.
At two o'clock she was clad in a general cinnamon buff; then a shade of glaucous green began to creep over head and upper eyelids, onward over her face, finally coloring body and limbs. Beneath, the little pollyfrog fairly glowed with bright apricot orange, throat and tail amparo purple, mouth green, and sides rich pale blue. To this maze of color we must add a strange, new expression, born of the prominent eyes, together with the line of the mouth extending straight back with a final jeering, upward lift; in front, the lower lip thick and protruding, which, with the slanting eyes, gave a leering, devilish smirk, while her set, stiff, exact posturecompelled a vivid thought of the sphinx. Never have I seen such a remarkable combination. It fascinated us. We looked at Guinevere, and then at the tadpoles swimming quietly in their tank, and evolution in its wildest conceptions appeared a tame truism.
This was the acme of Guinevere's change, the pinnacle of her development. Thereafter her transformations were rhythmical, alternating with the day and night. Through the nights of activity she was garbed in rich, warm brown. With the coming of dawn, as she climbed slowly upward, her color shifted through chestnut to maroon; this maroon then died out on the mid-back to a delicate, dull violet-blue, which in turn became obscured in the sunlight by turquoise, which crept slowly along the sides. Carefully and laboriously she clambered up, up to the topmost frond, and there performed her little toilet, scraping head and face with her hands, passing the hinder limbs over her back to brush off every grain of sand. The eyes had meanwhile lost their black-flecked, golden, nocturnal iridescence, and had gradually paled to a clear silvery blue, while the great pupil of darkness narrowed to a slit.
Little by little her limbs and digits were drawnin out of sight, and the tiny jeweled being crouched low, hoping for a day of comfortable clouds, a little moisture, and a swift passage of time to the next period of darkness, when it was fitting and right for Guineveres to seek their small meed of sustenance, to grow to frog's full estate, and to fulfil as well as might be what destiny the jungle offered. To unravel the meaning of it all is beyond even attempting. The breath of mist ever clouds the mirror, and only as regards a tiny segment of the life-history of Guinevere can I say, "There is no need to wipe the mirror."
Pterodactyl Pups led me to the wonderful Attas—the most astounding of the jungle labor-unions. We were all sitting on the Mazaruni bank, the night before the full moon, immediately in front of my British Guiana laboratory. All the jungle was silent in the white light, with now and then the splash of a big river fish. On the end of the bench was the monosyllabic Scot, who ceased the exquisite painting of mora buttresses and jungle shadows only for the equal fascination of searching bats for parasites. Then the great physician, who had come six thousand miles to peer into the eyes of birds and lizards in my dark-room, working with a gentle hypnotic manner that made the little beings seem to enjoy the experience. On my right sat an army captain, who had given more thought to the possible secrets of French chaffinches than to the approaching barrage. There was also the artist, who could draw a lizard's head like a Japaneseprint, but preferred to depict impressionistic Laocoön roots.
These and others sat with me on the long bench and watched the moonpath. The conversation had begun with possible former life on the moon, then shifted to Conan Doyle'sThe Lost World, based on the great Roraima plateau, a hundred and fifty miles west of where we were sitting. Then we spoke of the amusing world-wide rumor, which had started no one knows how, that I had recently discovered a pterodactyl. One delightful result of this had been a letter from a little English girl, which would have made a worthy chapter-subject forDream Days. For years she and her little sister had peopled a wood near her home with pterodactyls, but had somehow never quite seen one; and would I tell her a little about them—whether they had scales, or made nests; so that those in the wood might be a little easier to recognize.
When strange things are discussed for a long time, in the light of a tropical moon, at the edge of a dark, whispering jungle, the mind becomes singularly imaginative and receptive; and, as I looked through powerful binoculars at the great suspended globe, the dead craters and precipicesbecame very vivid and near. Suddenly, without warning, there flapped into my field, a huge shapeless creature. It was no bird, and there was nothing of the bat in its flight—the wings moved with steady rhythmical beats, and drove it straight onward. The wings were skinny, the body large and of a pale ashy hue. For a moment I was shaken. One of the others had seen it, and he, too, did not speak, but concentrated every sense into the end of the little tubes. By the time I had begun to find words, I realized that a giant fruit bat had flown from utter darkness across my line of sight; and by close watching we soon saw others. But for a very few seconds these Pterodactyl Pups, as I nicknamed them, gave me all the thrill of a sudden glimpse into the life of past ages. The last time I had seen fruit bats was in the gardens of Perideniya, Ceylon. I had forgotten that they occurred in Guiana, and was wholly unprepared for the sight of bats a yard across, with a heron's flight, passing high over the Mazaruni in the moonlight.
The talk ended on the misfortune of the configuration of human anatomy, which makes sky-searching so uncomfortable a habit. This outlook was probably developed to a greater extentduring the war than ever before; and I can remember many evenings in Paris and London when a sinister half-moon kept the faces of millions turned searchingly upward. But whether in city or jungle, sky-scanning is a neck-aching affair.
The following day my experience with the Pterodactyl Pups was not forgotten, and as a direct result of looking out for soaring vultures and eagles, with hopes of again seeing a white-plumaged King and the regal Harpy, I caught sight of a tiny mote high up in mid-sky. I thought at first it was a martin or swift; but it descended, slowly spiraling, and became too small for any bird. With a final, long, descending curve, it alighted in the compound of our bungalow laboratory and rested quietly—a great queen of the leaf-cutting Attas returning from her marriage flight. After a few minutes she stirred, walked a few steps, cleaned her antennæ, and searched nervously about on the sand. A foot away was a tiny sprig of indigo, the offspring of some seed planted two or three centuries ago by a thrifty Dutchman. In the shade of its three leaves the insect paused, and at once began scraping at the sand with her jaws. Sheloosened grain after grain, and as they came free they were moistened, agglutinated, and pressed back against her forelegs. When at last a good-sized ball was formed, she picked it up, turned around and, after some fussy indecision, deposited it on the sand behind her. Then she returned to the very shallow, round depression, and began to gather a second ball.
I thought of the first handful of sand thrown out for the base of Cheops, of the first brick placed in position for the Great Wall, of a fresh-cut trunk, rough-hewn and squared for a log-cabin on Manhattan; of the first shovelful of earth flung out of the line of the Panama Canal. Yet none seemed worthy of comparison with even what little I knew of the significance of this ant's labor, for this was earnest of what would make trivial the engineering skill of Egyptians, of Chinese patience, of municipal pride and continental schism.
Imagine sawing off a barn-door at the top of a giant sequoia, growing at the bottom of the Grand Cañon, and then, with five or six children clinging to it, descending the tree, and carrying it up the cañon walls against a subway rush of rude people, who elbowed and pushed blindlyagainst you. This is what hundreds of leaf-cutting ants accomplish daily, when cutting leaves from a tall bush, at the foot of the bank near the laboratory.
There are three dominant labor-unions in the jungle, all social insects, two of them ants, never interfering with each other's field of action, and all supremely illustrative of conditions resulting from absolute equality, free-and-equalness, communalism, socialism carried to the (forgive me!) anth power. The Army Ants are carnivorous, predatory, militant nomads; the Termites are vegetarian scavengers, sedentary, negative and provincial; the Attas, or leaf-cutting ants, are vegetarians, active and dominant, and in many ways the most interesting of all.
The casual observer becomes aware of them through their raids upon gardens; and indeed the Attas are a very serious menace to agriculture in many parts of the tropics, where their nests, although underground, may be as large as a house and contain millions of individuals. While their choice among wild plants is exceedingly varied, it seems that there are certain things they will not touch; but when any human-reared flower, vegetable, shrub, vine, or tree is planted,the Attas rejoice, and straightway desert the native vegetation to fall upon the newcomers. Their whims and irregular feeding habits make it difficult to guard against them. They will work all round a garden for weeks, perhaps pass through iten routeto some tree that they are defoliating, and then suddenly, one night, every Atta in the world seems possessed with a desire to work havoc, and at daylight the next morning, the garden looks like winter stubble—a vast expanse of stems and twigs, without a single remaining leaf. Volumes have been written, and a whole chemist's shop of deadly concoctions devised, for combating these ants, and still they go steadily on, gathering leaves which, as we shall see, they do not even use for food.
Although essentially a tropical family, Attas have pushed as far north as New Jersey, where they make a tiny nest, a few inches across, and bring to it bits of pine needles.
In a jungle Baedeker, we should double-star these insects, and paragraph them as "Atta, named by Fabricius in 1804; the Kartabo species,cephalotes; Leaf-cutting or Cushie or Parasol Ants; very abundant.Atta, a subgenus ofAtta, which is a genus ofAttii, which is a tribe ofMyrmicinæ,which is a subfamily ofFormicidæ," etc.
With a feeling of slightly greater intimacy, of mental possession, we set out, armed with a name of one hundred and seventeen years' standing, and find a big Atta worker carving away at a bit of leaf, exactly as his ancestors had done for probably one hundred and seventeen thousand years.
We gently lift him from his labor, and a drop of chloroform banishes from his ganglia all memory of the hundred thousand years of pruning. Under the lens his strange personality becomes manifest, and we wonder whether the old Danish zoölogist had in mind the slender toe-tips which support him, or in a chuckling mood made him a namesake of C. Quintius Atta. A close-up shows a very comic little being, encased in a prickly, chestnut-colored armor, which should make him fearless in a den of a hundred anteaters. The front view of his head is a bit mephistophelian, for it is drawn upward into two horny spines; but the side view recalls a little girl with her hair brushed very tightly up and back from her face.
The connection between Atta and the worldabout him is furnished by this same head: two huge, flail-shaped antennæ arching up like aerial, detached eyebrows—vehicles, through their golden pile, of senses which foil our most delicate tests. Outside of these are two little shoe-button eyes; and we are not certain whether they reflect to the head ganglion two or three hundred bits of leaf, or one large mosaic leaf. Below all is swung the pair of great scythes, so edged and hung that they can function as jaws, rip-saws, scissors, forceps, and clamps. The thorax, like the head of a titanothere, bears three pairs of horns—a great irregular expanse of tumbled, rock-like skin and thorn, a foundation for three pairs of long legs, and sheltering somewhere in its heart a thread of ant-life; finally, two little pedicels lead to a rounded abdomen, smaller than the head. This Third-of-an-inch is a worker Atta to the physical eye; and if we catch another, or ten, or ten million, we find that some are small, others much larger, but that all are cast in the same mold, all indistinguishable except, perhaps, to the shoe-button eyes.
When a worker has traveled along the Atta trails, and has followed the temporary mob-instinct and climbed bush or tree, the same irresistibleforce drives him out upon a leaf. Here, apparently, instinct slightly loosens its hold, and he seems to become individual for a moment, to look about, and to decide upon a suitable edge or corner of green leaf. But even in this he probably has no choice. At any rate, he secures a good hold and sinks his jaws into the tissue. Standing firmly on the leaf, he measures his distance by cutting across a segment of a circle, with one of his hind feet as a center. This gives a very true curve, and provides a leaf-load of suitable size. He does not scissor his way across, but bit by bit sinks the tip of one jaw, hook-like, into the surface, and brings the other up to it, slicing through the tissue with surprising ease. He stands upon the leaf, and I always expect to see him cut himself and his load free, Irishman-wise. But one or two of his feet have invariably secured a grip on the plant, sufficient to hold him safely. Even if one or two of his fellows are at work farther down the leaf, he has power enough in his slight grip to suspend all until they have finished and clambered up over him with their loads.
Holding his bit of leaf edge-wise, he bends his head down as far as possible, and secures a strong purchase along the very rim. Then, as he raiseshis head, the leaf rises with it, suspended high over his back, out of the way. Down the stem or tree-trunk he trudges, head first, fighting with gravitation, until he reaches the ground. After a few feet, or, measured by his stature, several hundred yards, his infallible instinct guides him around pebble boulders, mossy orchards, and grass jungles to a specially prepared path.
Thus in words, in sentences, we may describe the cutting of a single leaf; but only in the imagination can we visualize the cell-like or crystal-like duplication of this throughout all the great forests of Guiana and of South America. As I write, a million jaws snip through their stint; as you read, ten million Attas begin on new bits of leaf. And all in silence and in dim light, legions passing along the little jungle roads, unending lines of trembling banners, a political parade of ultra socialism, a procession of chlorophyll floats illustrating unreasoning unmorality, a fairy replica of "Birnam Forest come to Dunsinane."
In their leaf-cutting, Attas have mastered mass, but not form. I have never seen one cut off a piece too heavy to carry, but many ahard-sliced bit has had to be deserted because of the configuration of the upper edge. On almost any trail, an ant can be found with a two-inch stem of grass, attempting to pass under a twig an inch overhead. After five or ten minutes of pushing, backing, and pulling, he may accidentally march off to one side, or reach up and climb over; but usually he drops his burden. His little works have been wound up, and set at the mark "home"; and though he has now dropped the prize for which he walked a dozen ant-miles, yet any idea of cutting another stem, or of picking up a slice of leaf from those lying along the trail, never occurs to him. He sets off homeward, and if any emotion of sorrow, regret, disappointment, or secret relief troubles his ganglia, no trace of it appears in antennæ, carriage, or speed. I can very readily conceive of his trudging sturdily all the way back to the nest, entering it, and going to the place where he would have dumped his load, having fulfilled his duty in the spirit at least. Then, if there comes a click in his internal time-clock, he may set out upon another quest—more cabined, cribbed, and confined than any member of a Cook's tourist party.
I once watched an ant with a piece of leafwhich had a regular shepherd's crook at the top, and if his adventures of fifty feet could have been caught on a moving-picture film, Charlie Chaplin would have had an arthropod rival. It hooked on stems and pulled its bearer off his feet, it careened and ensnared the leaves of other ants, at one place mixing up with half a dozen. A big thistledown became tangled in it, and well-nigh blew away with leaf and all; hardly a foot of his path was smooth-going. But he persisted, and I watched him reach the nest, after two hours of tugging and falling and interference with traffic.
Occasionally an ant will slip in crossing a twiggy crevasse, and his leaf become tightly wedged. After sprawling on his back and vainly clawing at the air for a while, he gets up, brushes off his antennæ, and sets to work. For fifteen minutes I have watched an Atta in this predicament, stodgily endeavoring to lift his leaf while standing on it at the same time. The equation of push equaling pull is fourth dimensional to the Attas.
With all this terrible expenditure of energy, the activities of these ants are functional within very narrow limits. The blazing sun causes them to drop their burdens and flee for home; a heavywind frustrates them, for they cannot reef. When a gale arises and sweeps an exposed portion of the trail, their only resource is to cut away all sail and heave it overboard. A sudden downpour reduces a thousand banners and waving, bright-colored petals to débris, to be trodden under foot. Sometimes, after a ten-minute storm, the trails will be carpeted with thousands of bits of green mosaic, which the outgoing hordes will trample in their search for more leaves. On a dark night little seems to be done; but at dawn and dusk, and in the moonlight or clear starlight, the greatest activity is manifest.
Attas are such unpalatable creatures that they are singularly free from dangers. There is a tacit armistice between them and the other labor-unions. The army ants occasionally make use of their trails when they are deserted; but when the two great races of ants meet, each antennæs the aura of the other, and turns respectfully aside. When termites wish to traverse an Atta trail, they burrow beneath it, or build a covered causeway across, through which they pass and repass at will, and over which the Attas trudge, uncaring and unconscious of its significance.
Only creatures with the toughest of digestionswould dare to include these prickly, strong-jawed, meatless insects in a bill of fare. Now and then I have found an ani, or black cuckoo, with a few in its stomach: but an ani can swallow a stinging-haired caterpillar and enjoy it. The most consistent feeder upon Attas is the giant marine toad. Two hundred Attas in a night is not an uncommon meal, the exact number being verifiable by a count of the undigested remains of heads and abdomens.Bufo marinusis the gardener's best friend in this tropic land, and besides, he is a gentleman and a philosopher, if ever an amphibian was one.
While the cutting of living foliage is the chief aim in life of these ants, yet they take advantage of the flotsam and jetsam along the shore, and each low tide finds a column from some nearby nest salvaging flowerets, leaves, and even tiny berries. A sudden wash of tide lifts a hundred ants with their burdens and then sets them down again, when they start off as if nothing had happened.
The paths or trails of the Attas represent very remarkable feats of engineering, and wind about through jungle and glade for surprising distances. I once traced a very old and wide trailfor well over two hundred yards. Taking little Third-of-an-inch for a type (although he would rank as a rather large Atta), and comparing him with a six-foot man, we reckon this trail, ant-ratio, as a full twenty-five miles. Belt records a leaf-cutter's trail half a mile long, which would mean that every ant that went out, cut his tiny bit of leaf, and returned, would traverse a distance of a hundred and sixteen miles. This was an extreme; but our Atta may take it for granted, speaking antly, that once on the home trail, he has, at the least, four or five miles ahead of him.
The Atta roads are clean swept, as straight as possible, and very conspicuous in the jungle. The chief high-roads leading from very large nests are a good foot across, and the white sand of their beds is visible a long distance away. I once knew a family of opossums living in a stump in the center of a dense thicket. When they left at evening, they always climbed along as far as an Atta trail, dropped down to it, and followed it for twenty or thirty yards. During the rains I have occasionally found tracks of agoutis and deer in these roads. So it would be very possible for the Attas to lay the foundation for ananimal trail, and this,à lacalf-path, for the street of a future city.
The part that scent plays in the trails is evidenced if we scatter an inch or two of fresh sand across the road. A mass of ants banks against the strange obstruction on both sides, on the one hand a solid phalanx of waving green banners, and on the other a mob of empty-jawed workers with wildly waving antennæ. Scouts from both sides slowly wander forward, and finally reach one another and pass across. But not for ten minutes does anything like regular traffic begin again.
When carrying a large piece of leaf, and traveling at a fair rate of speed, the ants average about a foot in ten seconds, although many go the same distance in five. I tested the speed of an Atta, and then I saw that its leaf seemed to have a peculiar-shaped bug upon it, and picked it up with its bearer. Finding the blemish to be only a bit of fungus, I replaced it. Half an hour later I was seated by a trail far away, when suddenly my ant with the blemished spot appeared. It was unmistakable, for I had noticed that the spot was exactly that of the Egyptian symbol of life. I paced the trail, and found thatseventy yards away it joined the spot where I had first seen my friend. So, with occasional spurts, he had done two hundred and ten feet in thirty minutes, and this in spite of the fact that he had picked up a supercargo.
Two parts of hydrogen and one of oxygen, under the proper stimulus, invariably result in water; two and two, considered calmly and without passion, combine into four; the workings of instinct, especially in social insects, is so mechanical that its results can almost be demonstrated in formula; and yet here was my Atta leaf-carrier burdened with a minim. The worker Attas vary greatly in size, as a glance at a populous trail will show. They have been christenedmacrergates, desmergatesandmicrergates; or we may call the largest Maxims, the average middle class Mediums, and the tiny chaps Minims, and all have more or less separate functions in the ecology of the colony. The Minims are replicas in miniature of the big chaps, except that their armor is pale cinnamon rather than chestnut. Although they can bite ferociously, they are too small to cut through leaves, and they have very definite duties in the nest; yet they are foundwith every leaf-cutting gang, hastening along with their larger brethren, but never doing anything, that I could detect, at their journey's end. I have a suspicion that the little Minims, who are very numerous, function as light cavalry; for in case of danger they are as eager at attack as the great soldiers, and the leaf-cutters, absorbed in their arduous labor, would benefit greatly from the immunity ensured by a flying corps of their little bulldog comrades.
I can readily imagine that these nestling Minims become weary and foot-sore (like bank-clerks guarding a reservoir), and if instinct allows such abominable individuality, they must often wish themselves back at the nest, for every mile of a Medium is three miles to them.
Here is where our mechanical formula breaks down; for, often, as many as one in every five leaves that pass bears aloft a Minim or two, clinging desperately to the waving leaf and getting a free ride at the expense of the already overburdened Medium. Ten is the extreme number seen, but six to eight Minims collected on a single leaf is not uncommon. Several times I have seen one of these little banner-riders shift deftlyfrom leaf to leaf, when a swifter carrier passed by, as a circus bareback rider changes steeds at full gallop.
Once I saw enacted above ground, and in the light of day, something which may have had its roots in ananlageof divine discontent. If I were describing the episode half a century ago, I should entitle it, "The Battle of the Giants, or Emotion Enthroned." A quadruple line of leaf-carriers was disappearing down a hole in front of the laboratory, bumped and pushed by an out-pouring, empty-jawed mass of workers. As I watched them, I became aware of an area of great excitement beyond the hole. Getting down as nearly as possible to ant height, I witnessed a terrible struggle. Two giants—of the largest soldier Maxim caste—were locked in each other's jaws, and to my horror, I saw that each had lost his abdomen. The antennæ and the abdomen petiole are the only vulnerable portions of an Atta, and long after he has lost these apparently dispensable portions of his anatomy, he is able to walk, fight, and continue an active but erratic life. These mighty-jawed fellows seem never to come to the surface unless danger threatens; and my mind went down into theblack, musty depths, where it is the duty of these soldiers to walk about and wait for trouble. What could have raised the ire of such stolid neuters against one another? Was it sheer lack of something to do? or was there a cell or two of the winged caste lying fallow within their bodies, which, stirring at last, inspired a will to battle, a passing echo of romance, of the activities of the male Atta?
Their unnatural combat had stirred scores of smaller workers to the highest pitch of excitement. Now and then, out of the mêlée, a Medium would emerge, with a tiny Minim in his jaws. One of these carried his still living burden many feet away, along an unused trail, and dropped it. I examined the small ant, and found that it had lost an antenna, and its body was crushed. When the ball of fighters cleared, twelve small ants were seen clinging to the legs and heads of the mutilated giants, and now and then these would loosen their hold on each other, turn, and crush one of their small tormenters. Several times I saw a Medium rush up and tear a small ant away, apparently quite insane with excitement.
Occasionally the least exhausted giant wouldstagger to his four and a half remaining legs, hoist his assailant, together with a mass of the midgets, high in air, and stagger for a few steps, before falling beneath the onrush of new attackers. It made me wish to help the great insect, who, for aught I knew, was doomed because he was different—because he had dared to be an individual.
I left them struggling there, and half an hour later, when I returned, the episode was just coming to a climax. My Atta hero was exerting his last strength, flinging off the pile that assaulted him, fighting all the easier because of the loss of his heavy body. He lurched forward, dragging the second giant, now dead, not toward the deserted trail or the world of jungle around him, but headlong into the lines of stupid leaf-carriers, scattering green leaves and flower-petals in all directions. Only when dozens of ants threw themselves upon him, many of them biting each other in their wild confusion, did he rear up for the last time, and, with the whole mob, rolled down into the yawning mouth of the Atta nesting-hole, disappearing from view, and carrying with him all those hurrying up the steep sides. It was a great battle. I was breathingfast with sympathy, and whatever his cause, I was on his side.
The next day both giants were lying on the old, disused trail; the revolt against absolute democracy was over; ten thousand ants passed to and fro without a dissenting thought, or any thought, and the Spirit of the Attas was content.
