And this was only the beginning of complexity. For with the quickening of the larva came a reaction on the part of the plant, which, in defense, set up a greatly accelerated growth about the young insect.
This might have taken the form of some distorted or deformed plant organ--a cl.u.s.ter of leaves, a fruit or berry or tuft of hairs, wholly unlike the characters of the plant itself. My weed was studded with what might well have been normal seed-fruits, were they not proved nightmares of berries, awful pseudo-fruits sprouting from horridly impossible places. And this excess of energy, expressed in tumorous outgrowths, was all vitally useful to the grub--just as the skilful jiu-jitsu wrestler accomplishes his purpose with the aid of his opponent's strength. The insect and plant were, however, far more intricately related than any two human compet.i.tors: for the grub in turn required the continued health and strength of the plant for its existence; and when I plucked a leaf, I knew I had doomed all the hidden insects living within its substance.
The galls at my hand simulated little acorns, dull greenish in color, matching the leaf-surface on which they rested, and rising in a sharp point. I cut one through and, when wearied and fretted with the responsibilities of independent existence, I know I shall often recall and envy my grub in his palatial parasitic home. Outside came a rather hard, brown protective sheath; then the main body of the gall, of firm and dense tissue; and finally, at the heart, like the Queen's chamber in Cheops, the irregular little dwelling-place of the grub. This was not empty and barren; but the blackness and silence of this vegetable chamber, this architecture fas.h.i.+oned by the strangest of builders for the most remarkable of tenants, was filled with a nap of long, crystalline hairs or threads like the spun-gla.s.s candy in our Christmas sweetshops--white at the base and shading from pale salmon to the deepest of pinks. This exquisite tapestry, whose beauties were normally forever hidden as well from the blind grub as from the outside world, was the ambrosia all unwittingly provided by the antagonism of the plant; the nutrition of resentment, the food of defiance; and day by day the grub gradually ate his way from one end to the other of his suite, laying a normal, healthful physical foundation for his future aerial activities.
The natural history of galls is full of romance and strange unrealities, but to-day it meant to me only a renewed instance of an opportunity seized and made the most of; the success of the indirect, the unreasonable--the long chance which so few of us humans are willing to take, although the reward is a perpetual enthusiasm for the happening of the moment, and the honest gambler's joy for the future.
How much more desirable to acquire merit as a footless grub in the heart of a home, erected and precariously nourished by a worthy opponent, with a future of unnumbered possibilities, than to be a queen-mother in nest or hive--cared-for, fed, and cleansed by a host of slaves, but with less prospect of change or of adventure than an average toadstool.
Thus I sat for a long time, lulled by similitudes of northern plants and bees and birds, and then gently s.h.i.+fted southward a few hundred miles, the transition being smooth and unabrupt. With equal gentleness the dead calm stirred slightly and exhaled the merest ghost of a breeze; it seemed as if the air was hardly in motion, but only restless: the wings of the bees and the flycatcher might well have caused it. But, judged by the sequence of events, it was the almost imperceptible signal given by some great Jungle Spirit, who had tired of playing with my dreams and pleasant fancies of northern life, and now called upon her legions to disillusion me. And the response was immediate. Three great sh.e.l.ls burst at my very feet,--one of sound, one of color, and the third of both plus numbers,--and from that time on, tropical life was dominant whichever way I looked. That is the way with the wilderness, and especially the tropical wilderness--to surprise one in the very field with which one is most familiar. While in my own estimation my chief profession is ignorance, yet I sign my pa.s.sport applications and my jury evasions as Ornithologist. And now this playful Spirit of the Jungle permitted me to meditate cheerfully on my ability to compare the faunas of New York and Guiana, and then proceeded to startle me with three salvos of birds, first physically and then emotionally.
From the monotone of under-world sounds a strange little rasping detached itself, a reiterated, subdued sc.r.a.ping or picking. It carried my mind instantly to the throbbing theme of the Niebelungs, onomatopoetic of the little hammers forever busy in their underground work. I circled a small bush at my side, and found that the sound came from one of the branches near the top; so with my gla.s.ses I began a systematic search. It was at this propitious moment, when I was relaxed in every muscle, steeped in the quiet of this hillside, and keen on discovering the beetle, that the first sh.e.l.l arrived. If I had been less absorbed I might have heard some distant chattering or calling, but this time it was as if a Spad had shut off its power, volplaned, kept ahead of its own sound waves, and bombed me. All that actually happened was that a band of little parrakeets flew down and alighted nearby. When I discovered this, it seemed a disconcerting anti-climax, just as one can make the bravest man who has been under rifle-fire flinch by spinning a match swiftly past his ear.
I have heard this sound of parrakeet's wings, when the birds were alighting nearby, half a dozen times; but after half a hundred I shall duck just as spontaneously, and for a few seconds stand just as immobile with astonishment. From a volcano I expect deep and sinister sounds; when I watch great breakers I would marvel only if the accompanying roar were absent; but on a calm sunny August day I do not expect a noise which, for suddenness and startling character, can be compared only with a tremendous flash of lightning. Imagine a wonderful tapestry of strong ancient stuff, which had only been woven, never torn, and think of this suddenly ripped from top to bottom by some sinister, irresistible force.
In the instant that the sound began, it ceased; there was no echo, no bell-like sustained overtones; both ends were buried in silence. As it came to-day it was a high tearing crash which shattered silence as a Very light destroys darkness; and at its cessation I looked up and saw twenty little green figures gazing intently down at me, from so small a sapling that their addition almost doubled the foliage. That their small wings could wring such a sound from the fabric of the air was unbelievable. At my first movement, the flock leaped forth, and if their wings made even a rustle, it was wholly drowned in the chorus of chattering cries which poured forth unceasingly as the little band swept up and around the sky circle. As an alighting morpho b.u.t.terfly dazzles the eyes with a final flash of his blazing azure before vanis.h.i.+ng behind the leaves and fungi of his lower surface, so parrakeets change from screaming motes in the heavens to silence, and then to a hurtling, roaring boomerang, whose amazing unexpectedness would distract the most dangerous eyes from the little motionless leaf-figures in a neighboring treetop.
When I sat down again, the whole feeling of the hillside was changed.
I was aware that my weed was a northern weed only in appearance, and I should not have been surprised to see my bees change to flies or my lizards to snakes--tropical beings have a way of doing such things.
The next phenomenon was color,--unreal, living pigment,--which seemed to appeal to more than one sense, and which satisfied, as a cooling drink or a rare, delicious fragrance satisfies. A medium-sized, stocky bird flew with steady wing-beats over the jungle, in black silhouette against the sky, and swung up to an outstanding giant tree which partly overhung the edge of my clearing. The instant it pa.s.sed the zone of green, it flashed out brilliant turquoise, and in the same instant I recognized it and reached for my gun. Before I retrieved the bird, a second, dull and dark-feathered, flew from the tree. I had watched it for some time, but now, as it pa.s.sed over, I saw no yellow and knew it too was of real scientific interest to me; and with the second barrel I secured it. Picking up my first bird, I found that it was not turquoise, but beryl; and a few minutes later I was certain that it was aquamarine; on my way home another glance showed the color of forget-me-nots on its plumage, and as I looked at it on my table, it was Nile green. Yet the feathers were painted in flat color, without especial sheen or iridescence, and when I finally a.n.a.lyzed it, I found it to be a delicate calamine blue. It actually had the appearance of a too strong color, as when a glistening surface reflects the sun. From beak to tail it threw off this glowing hue, except for its chin and throat, which were a limpid amaranth purple; and the effect on the excited rods and cones in one's eyes was like the power of great music or some majestic pa.s.sage in the Bible. You, who think my similes are overdone, search out in the nearest museum the dustiest of purple-throated cotingas,--_Cotinga cayana,_--and then, instead, berate me for inadequacy.
Sheer color alone is powerful enough, but when heightened by contrast, it becomes still more effective, and I seemed to have secured, with two barrels, a cotinga and its shadow. The latter was also a full-grown male cotinga, known to a few people in this world as the dark-breasted mourner (_Lipaugus simplex_). In general shape and form it was not unlike its cousin, but in color it was its shadow, its silhouette. Not a feather upon head or body, wings or tail showed a hint of warmth, only a dull uniform gray; an ash of a bird, living in the same warm sunlight, wet by the same rain, feeding on much the same food, and claiming relations.h.i.+p with a blazing-feathered turquoise.
There is some very exact and very absorbing reason for all this, and for it I search with fervor, but with little success. But we may be certain that the causes of this and of the host of other unreasonable realities which fill the path of the evolutionist with never-quenched enthusiasm, will extend far beyond the colors of two tropical birds.
They will have something to do with flowers and with bright b.u.t.terflies, and we shall know why our "favorite color" is more than a whim, and why the Greeks may not have been able to distinguish the full gamut of our spectrum, and why rainbows are so narrow to our eyes in comparison to what they might be.
Finally, there was thrown aside all finesse, all delicacy of presentation, and the last lingering feeling of temperate life and nature was erased. From now on there was no confusion of zones, no concessions, no mental palimpsest of resolving images. The spatial, the temporal,--the hillside, the pa.s.sing seconds,--the vibrations and material atoms stimulating my five senses, all were tropical, quickened with the unbelievable vitality of equatorial life. A rustling came to my ears, although the breeze was still little more than a sensation of coolness. Then a deep whirr sounded overhead, and another, and another, and with a rush a dozen great toucans were all about me. Monstrous beaks, parodies in pastels of unheard-of blues and greens, b.r.e.a.s.t.s which glowed like mirrored suns,--orange overlaid upon blinding yellow,--and at every flick of the tail a trenchant flash of intense scarlet. All these colors set in frames of jet-black plumage, and suddenly hurled through blue sky and green foliage, made the hillside a brilliant moving kaleidoscope.
Some flew straight over, with several quick flaps, then a smooth glide, flaps and glide. A few banked sharply at sight of me, and wheeled to right or left. Others alighted and craned their necks in suspicion; but all sooner or later disappeared eastward in the direction of a mighty jungle tree just bursting into a myriad of berries. They were sulphur-breasted toucans, and they were silent, heralded only by the sound of their wings and the crash of their pigments. I can think of no other a.s.semblage of jungle creatures more fitted to impress one with the prodigality of tropical nature. Four years before, we set ourselves to work to discover the first eggs and young of toucans, and after weeks of heartbreaking labor and disappointments we succeeded. Out of the five species of toucans living in this part of Guiana we found the nests of four, and the one which eluded us was the big sulphur-breasted fellow. I remembered so vividly the painstaking care with which, week after week, we and our Indians tramped the jungle for miles,--through swamps and over rolling hills,--at last having to admit failure; and now I sat and watched thirty, forty, fifty of the splendid birds whirr past. As the last of the fifty-four flew on to their feast of berries, I recalled with difficulty my faded visions of northern birds.
And so ended, as in the great finale of a pyrotechnic display, my two hours on a hillside clearing. I can neither enliven it with a startling escape, nor add a thrill of danger, without using as many "ifs" as would be needed to make a Jersey meadow untenable. For example, _if_ I had fallen over backwards and been powerless to rise or move, I should have been killed within half an hour, for a stray column of army ants was pa.s.sing within a yard of me, and death would await any helpless being falling across their path. But by searching out a copperhead and imitating Cleopatra, or with patience and persistence devouring every toadstool, the same result could be achieved in our home-town orchard. When on the march, the army ants are as innocuous at two inches as at two miles. Had I sat where I was for days and for nights, my chief danger would have been demise from sheer chagrin at my inability to grasp the deeper significance of life and its earthly activities.
III
THE HOME TOWN OF THE ARMY ANTS
From uniform to civilian clothes is a change transcending mere alteration of stuffs and b.u.t.tons. It is scarcely less sweeping than the s.h.i.+ft from civilian clothes to bathing-suit, which so often compels us to concentrate on remembered mental attributes, to avoid demanding a renewed introduction to estranged personality. In the home life of the average soldier, the relaxation from sustained tension and conscious routine results in a gentleness and quietness of mood for which warrior nations are especially remembered.
Army ants have no insignia to lay aside, and their swords are too firmly hafted in their own beings to be hung up as post-bellum mural decorations, or--as is done only in poster-land--metamorphosed into pruning-hooks and plowshares.
I sat at my laboratory table at Kartabo, and looked down river to the pink roof of Kalac.o.o.n, and my mind went back to the shambles of Pit Number Five.[1] I was wondering whether I should ever see the army ants in any guise other than that of scouting, battling searchers for living prey, when a voice of the jungle seemed to hear my unexpressed wish. The sharp, high notes of white-fronted antbirds--those white-crested watchers of the ants--came to my ears, and I left my table and followed up the sound. Physically, I merely walked around the bungalow and approached the edge of the jungle at a point where we had erected a small outhouse a day or two before. But this two hundred feet might just as well have been a single step through quicksilver, hand in hand with Alice, for it took me from a world of hyoids and syrinxes, of vials and lenses and clean-smelling xylol, to the home of the army ants.
[Footnote 1: See _Jungle Peace_, p. 211.]
The antbirds were chirping and hopping about on the very edge of the jungle, but I did not have to go that far. As I pa.s.sed the doorless entrance of the outhouse I looked up, and there was an immense ma.s.s of some strange material suspended in the upper corner. It looked like stringy, chocolate-colored tow, studded with hundreds of tiny ivory b.u.t.tons. I came closer and looked carefully at this mushroom growth which had appeared in a single night, and it was then that my eyes began to perceive and my mind to record, things that my reason besought me to reject. Such phenomena were all right in a dream, or one might imagine them and tell them to children on one's knee, with wind in the eaves--wild tales to be laughed at and forgotten. But this was daylight and I was a scientist; my eyes were in excellent order, and my mind rested after a dreamless sleep; so I had to record what I saw in that little outhouse.
This chocolate-colored ma.s.s with its myriad ivory dots was the home, the nest, the hearth, the nursery, the bridal suite, the kitchen, the bed and board of the army ants. It was the focus of all the lines and files which ravaged the jungle for food, of the battalions which attacked every living creature in their path, of the unnumbered rank and file which made them known to every Indian, to every inhabitant of these vast jungles.
Louis Quatorze once said, "_L'Etat, c'est moi!_" but this figure of speech becomes an empty, meaningless phrase beside what an army ant could boast,--"_La maison, c'est moi!_" Every rafter, beam, stringer, window-frame and door-frame, hall-way, room, ceiling, wall and floor, foundation, superstructure and roof, all were ants--living ants, distorted by stress, crowded into the dense walls, spread out to widest stretch across tie-s.p.a.ces. I had thought it marvelous when I saw them arrange themselves as bridges, walks, handrails, b.u.t.tresses, and sign-boards along the columns; but this new absorption of environment, this usurpation of wood and stone, this insinuation of themselves into the province of the inorganic world, was almost too astounding to credit.
All along the upper rim the sustaining structure was more distinctly visible than elsewhere. Here was a maze of taut brown threads stretching in places across a span of six inches, with here and there a tiny knot. These were actually tie-strings of living ants, their legs stretched almost to the breaking-point, their bodies the inconspicuous knots or nodes. Even at rest and at home, the army ants are always prepared, for every quiescent individual in the swarm was standing as erect as possible, with jaws widespread and ready, whether the great curved mahogany scimitars of the soldiers, or the little black daggers of the smaller workers. And with no eyelids to close, and eyes which were themselves a mockery, the nerve shriveling and never reaching the brain, what could sleep mean to them? Wrapped ever in an impenetrable cloak of darkness and silence, life was yet one great activity, directed, ordered, commanded by scent and odor alone.
Hour after hour, as I sat close to the nest, I was aware of this odor, sometimes subtle, again wafted in strong successive waves. It was musty, like something sweet which had begun to mold; not unpleasant, but very difficult to describe; and in vain I strove to realize the importance of this faint essence--taking the place of sound, of language, of color, of motion, of form.
I recovered quickly from my first rapt realization, for a dozen ants had lost no time in ascending my shoes, and, as if at a preconcerted signal, all simultaneously sank their jaws into my person. Thus strongly recalled to the realities of life, I realized the opportunity that was offered and planned for my observation. No living thing could long remain motionless within the sphere of influence of these six-legged Boches, and yet I intended to spend days in close proximity. There was no place to hang a hammock, no overhanging tree from which I might suspend myself spider-wise. So I sent Sam for an ordinary chair, four tin cans, and a bottle of disinfectant. I filled the tins with the tarry fluid, and in four carefully timed rushes I placed the tins in a chair-leg square. The fifth time I put the chair in place beneath the nest, but I had misjudged my distances and had to retreat with only two tins in place. Another effort, with Spartan-like disregard of the fiery bites, and my haven was ready. I hung a bag of vials, notebook, and lens on the chairback, and, with a final rush, climbed on the seat and curled up as comfortably as possible.
All around the tins, swarming to the very edge of the liquid, were the angry hosts. Close to my face were the lines ascending and descending, while just above me were hundreds of thousands, a bushel-basket of army ants, with only the strength of their threadlike legs as suspension cables. It took some time to get used to my environment, and from first to last I was never wholly relaxed, or quite unconscious of what would happen if a chair-leg broke, or a bamboo fell across the outhouse.
I swiveled round on the chair-seat and counted eight lines of army ants on the ground, converging to the post at my elbow. Each was four or five ranks wide, and the eight lines occasionally divided or coalesced, like a nexus of capillaries. There was a wide expanse of sand and clay, and no apparent reason why the various lines of foragers should not approach the nest in a single large column. The dividing and redividing showed well how completely free were the columns from any individual dominance. There was no control by specific individuals or soldiers, but, the general route once established, the governing factor was the odor of contact.
The law to pa.s.s where others have pa.s.sed is immutable, but freedom of action or individual desire dies with the malleable, plastic ends of the foraging columns. Again and again came to mind the comparison of the entire colony or army with a single organism; and now the home, the nesting swarm, the focus of central control, seemed like the body of this strange amorphous organism--housing the spirit of the army.
One thinks of a column of foragers as a tendril with only the tip sensitive and growing and moving, while the corpuscle-like individual ants are driven in the current of blind instinct to and fro, on their chemical errands. And then this whole theory, this most vivid simile, is quite upset by the sights that I watch in the suburbs of this ant home!
The columns were most excellent barometers, and their reaction to pa.s.sing showers was invariable. The clay surface held water, and after each downfall the pools would be higher, and the contour of the little region altered. At the first few drops, all the ants would hasten, the throbbing corpuscles speeding up. Then, as the rain came down heavier, the column melted away, those near each end hurrying to shelter and those in the center crawling beneath fallen leaves and bits of clod and sticks. A moment before, hundreds of ants were trudging around a tiny pool, the water lined with ant handrails, and in shallow places, veritable formicine pontoons,--large ants which stood up to their bodies in water, with the booty-laden host pa.s.sing over them. Now, all had vanished, leaving only a bare expanse of splas.h.i.+ng drops and wet clay. The sun broke through and the residue rain tinkled from the bamboos.
As gradually as the growth of the rainbow above the jungle, the lines reformed themselves. Scouts crept from the jungle-edge at one side, and from the post at my end, and felt their way, fan-wise, over the rain-scoured surface; for the odor, which was both sight and sound to these ants, had been washed away--a more serious handicap than mere change in contour. Swiftly the wandering individuals found their bearings again. There was deep water where dry land had been, but, as if by long-planned study of the work of sappers and engineers, new pontoon bridges were thrown across, washouts filled in, new cliffs explored, and easy grades established; and by the time the bamboos ceased their own private after-shower, the columns were again running smoothly, battalions of eager light infantry hastening out to battle, and equal hosts of loot-laden warriors hurrying toward the home nest.
Four minutes was the average time taken to reform a column across the ten feet of open clay, with all the road-making and engineering feats which I have mentioned, on the part of ants who had never been over this new route before.
Leaning forward within a few inches of the post, I lost all sense of proportion, forgot my awkward human size, and with a new perspective became an equal of the ants, looking on, watching every pa.s.ser-by with interest, straining with the bearers of the heavy loads, and breathing more easily when the last obstacle was overcome and home attained. For a period I plucked out every bit of good-sized booty and found that almost all were portions of scorpions from far-distant dead logs in the jungle, creatures whose strength and poisonous stings availed nothing against the attacks of these fierce ants. The loads were adjusted equably, the larger pieces carried by the big, white-headed workers, while the smaller ants transported small eggs and larvae. Often, when a great mandibled soldier had hold of some insect, he would have five or six tiny workers surrounding him, each grasping any projecting part of the loot, as if they did not trust him in this menial capacity,--as an anxious mother would watch with doubtful confidence a big policeman wheeling her baby across a crowded street. These workers were often diminutive Marcelines, hindering rather than aiding in the progress. But in every phase of activity of these ants there was not an ounce of intentionally lost power, or a moment of time wilfully gone to waste. What a commentary on Bolshevism!
Now that I had the opportunity of quietly watching the long, hurrying columns, I came hour by hour to feel a greater intimacy, a deeper enthusiasm for their vigor of existence, their unfailing life at the highest point of possibility of achievement. In every direction my former desultory observations were discounted by still greater accomplishments. Elsewhere I have recorded the average speed as two and a half feet in ten seconds, estimating this as a mile in three and a half hours. An observant colonel in the American army has laid bare my congenitally hopeless mathematical inaccuracy, and corrected this to five hours and fifty-two seconds. Now, however, I established a wholly new record for the straight-away dash for home of the army ants. With the handicap of gravity pulling them down, the ants, both laden and unburdened, averaged ten feet in twenty seconds, as they raced up the post. I have now called in an artist and an astronomer to verify my results, these two being the only living beings within hailing distance as I write, except a baby red howling monkey curled up in my lap, and a toucan, sloth, and green boa, beyond my laboratory table. Our results are identical, and I can safely announce that the amateur record for speed of army ants is equivalent to a mile in two hours and fifty-six seconds; and this when handicapped by gravity and burdens of food, but with the incentive of approaching the end of their long journey.
As once before, I accidentally disabled a big worker that I was robbing of his load, and his entire abdomen rolled down a slope and disappeared. Hours later in the afternoon, I was summoned to view the same soldier, unconcernedly making his way along an outward-bound column, guarding it as carefully as if he had not lost the major part of his anatomy. His mandibles were ready, and the only difference that I could see was that he could make better speed than others of his caste. That night he joined the general a.s.semblage of cripples quietly awaiting death, halfway up to the nest.
I know of no highway in the world which surpa.s.ses that of a big column of army ants in exciting happenings, although I usually had the feeling which inspired Kim as he watched the Great White Road, of understanding so little of all that was going on. Early in the morning there were only outgoing hosts; but soon eddies were seen in the swift current, vortexes made by a single ant here and there forcing its way against the stream. Unlike penguins and human beings, army ants have no rule of the road as to right and left, and there is no lessening of pace or turning aside for a heavily laden drogher. Their blindness caused them to b.u.mp squarely into every individual, often sending load and carrier tumbling to the bottom of a vertical path. Another constant loss of energy was a large c.o.c.kroach leg, or scorpion segment, carried by several ants. Their insistence on trying to carry everything beneath their bodies caused all sorts of comical mishaps.
When such a large piece of booty appeared, it was too much of a temptation, and a dozen outgoing ants would rush up and seize hold for a moment, the consequent pulling in all directions reducing progress at once to zero.
Until late afternoon few ants returned without carrying their bit. The exceptions were the cripples, which were numerous and very pitiful.
From such fierce strenuousness, such virile activity, as unending as elemental processes, it seemed a very terrible drop to disability, to the utilizing of every atom of remaining strength to return to the temporary home nest--that instinct which drives so many creatures to the same homing, at the approach of death.
Even in their helplessness they were wonderful. To see a big black-headed worker struggling up a post with five short stumps and only one good hind leg, was a lesson in achieving the impossible. I have never seen even a suspicion of aid given to any cripple, no matter how slight or how complete the disability; but frequently a strange thing occurred, which I have often noticed but can never explain. One army ant would carry another, perhaps of its own size and caste, just as if it were a bit of dead provender; and I always wondered if cannibalism was to be added to their habits. I would capture both, and the minute they were in the vial, the dead ant would come to life, and with equal vigor and fury both would rush about their prison, seeking to escape, becoming indistinguishable in the twinkling of an eye.
Very rarely an ant stopped and attempted to clean another which had become partly disabled through an acc.u.mulation of gummy sap or other enc.u.mbering substance. But when a leg or other organ was broken or missing, the odor of the ant-blood seemed to arouse only suspicion and to banish sympathy, and after a few casual wavings of antennae, all pa.s.sed by on the other side. Not only this, but the unfortunates were actually in danger of attack within the very lines of traffic of the legionaries. Several times I noticed small rove-beetles accompanying the ants, who paid little attention to them. Whenever an ant became suspicious and approached with a raised-eyebrow gesture of antennae, the beetles turned their backs quickly and raised threatening tails. But I did not suspect the vampire or thug-like character of these guests--tolerated where any other insect would have been torn to pieces at once. A large crippled worker, hobbling along, had slipped a little away from the main line, when I was astonished to see two rove-beetles rush at him and bite him viciously, a third coming up at once and joining in. The poor worker had no possible chance against this combination, and he went down after a short, futile struggle. Two small army ants now happened to pa.s.s, and after a preliminary whiffing with waving antennae, rushed joyously into the _melee_. The beetles had a cowardly weapon, and raising their tails, ejected a drop or two of liquid, utterly confusing the ants, which turned and hastened back to the column. For the next few minutes, until the scent wore off, they aroused suspicion wherever they went. Meanwhile, the hyena-like rove-beetles, having hedged themselves within a barricade of their malodor, proceeded to feast, quarreling with one another as such cowards are wont to do.
Thus I thought, having identified myself with the army ants. From a broader, less biased point of view, I realized that credit should be given to the rove-beetles for having established themselves in a zone of such constant danger, and for being able to live and thrive in it.
The columns converged at the foot of the post, and up its surface ran the main artery of the nest. Halfway up, a flat board projected, and here the column divided for the last time, half going on directly into the nest, and the other half turning aside, skirting the board, ascending a bit of perpendicular canvas, and entering the nest from the rear. The entrance was well guarded by a veritable moat and drawbridge of living ants. A foot away, a flat mat of ants, mandibles outward, was spread, over which every pa.s.sing individual stepped. Six inches farther, and the sides of the mat thickened, and in the last three inches these sides met overhead, forming a short tunnel at the end of which the nest began.
And here I noticed an interesting thing. Into this organic moat or tunnel, this living mouth of an inferno, pa.s.sed all the booty-laden foragers, or those who for some reason had returned empty-mouthed. But the outgoing host seeped gradually from the outermost nest-layer--a gradual but fundamental circulation, like that of ocean currents.
Scorpions, eggs, caterpillars, gla.s.s-like wasp pupae, roaches, spiders, crickets,--all were drawn into the nest by a maelstrom of hunger, funneling into the narrow tunnel; while from over all the surface of the swarm there crept forth layer after layer of invigorated, implacable seekers after food.
The ma.s.s of ants composing the nest appeared so loosely connected that it seemed as if a touch would tear a hole, a light wind rend the supports. It was suspended in the upper corner of the doorway, rounded on the free sides, and measured roughly two feet in diameter--an unnumbered host of ants. Those on the surface were in very slow but constant motion, with legs s.h.i.+fting and antennae waving continually.
This quivering on the surface of the swarm gave it the appearance of the fur of some terrible animal--fur blowing in the wind from some unknown, deadly desert. Yet so cohesive was the entire ma.s.s, that I sat close beneath it for the best part of two days and not more than a dozen ants fell upon me. There was, however, a constant rain of egg-cases and pupa-skins and the remains of scorpions and gra.s.shoppers, the residue of the booty which was being poured in.
These wrappings and inedible casing were all brought to the surface and dropped. This was reasonable, but what I could not comprehend was a constant falling of small living larvae. How anything except army ants could emerge alive from such a sinister swarm was inconceivable.
It took some resolution to stand up under the nest, with my face only a foot away from this slowly seething ma.s.s of widespread jaws. But I had to discover where the falling larvae came from, and after a time I found that they were immature army ants. Here and there a small worker would appear, carrying in its mandibles a young larva; and while most made their way through the maze of mural legs and bodies and ultimately disappeared again, once in a while the burden was dropped and fell to the floor of the outhouse. I can account for this only by presuming that a certain percentage of the nurses were very young and inexperienced workers and dropped their burdens inadvertently. There was certainly no intentional casting out of these offspring, as was so obviously the case with the debris from the food of the colony. The eleven or twelve ants which fell upon me during my watch were all smaller workers, no larger ones losing their grip.
