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,ifI 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 passing 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 twoinches 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.
From uniform to civilian clothes is a change transcending mere alteration of stuffs and buttons. It is scarcely less sweeping than the shift 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 Kalacoon, and my mind went back to the shambles of PitNumber 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.

[1]SeeJungle 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 passed the doorless entrance of the outhouse I looked up, and there was an immense mass of some strange material suspended in the upper corner. It looked like stringy, chocolate-colored tow, studded with hundreds of tiny ivory buttons. I came closer and lookedcarefully 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 mass 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-spaces. I had thought it marvelous when I saw them arrange themselves as bridges, walks, handrails, buttresses, 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 withno 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 countedeight 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 pass where others have passed 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 passing 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 passing over them. Now, all had vanished, leaving only a bare expanse of splashing 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 passer-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 larvæ. 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 theamateur 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 assemblage of cripples quietly awaiting death, halfway up to the nest.
I know of no highway in the world which surpasses 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, vortexesmade 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 bump 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 cockroach 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 instinctwhich 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 accumulation of gummy sap or other encumbering substance. But when a leg or other organ was broken or missing, the odor of the ant-blood seemed to arouse only suspicion andto banish sympathy, and after a few casual wavings of antennæ, all passed 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 antennæ, 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 pass, and after a preliminary whiffing with waving antennæ, rushed joyously into themêlée. The beetles had a cowardly weapon, and raising their tails, ejected a drop or two of liquid, utterly confusing the ants, which turned and hastenedback 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 passing individual stepped. Six inches farther, and the sides of the mat thickened, and in the lastthree 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, passed 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, glass-like wasp pupæ, 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 mass 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 shifting and antennæ waving continually. This quivering on the surface of the swarm gave itthe appearance of the fur of some terrible animal—fur blowing in the wind from some unknown, deadly desert. Yet so cohesive was the entire mass, 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 grasshoppers, 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 larvæ. 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 mass of widespread jaws. But I had to discover where the falling larvæ 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 theouthouse. 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 débris 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.
While recording some of these facts, I dropped my pencil, and it was fully ten minutes before the black mass of enraged insects cleared away, and I could pick it up. Leaning far over to secure it, I was surprised by the cleanliness of the floor around my chair. My clothes and note-paper had been covered with loose wings, dry skeletons of insects and the other débris, while hundreds of other fragments had sifted down past me. Yet now that I looked seeingly, the whole area was perfectly clean. I had to assume a perfect jack-knife pose to get my face near enough to the floor; but, achieving it, I found about five hundred ants serving as a street-cleaning squad. They roamed aimlessly about over the whole floor, ready at once to attack anythingof mine, or any part of my anatomy which might come close enough, but otherwise stimulated to activity only when they came across a bit of rubbish from the nest high overhead. This was at once seized and carried off to one of two neat piles in far corners. Before night these kitchen middens were an inch or two deep and nearly a foot in length, composed, literally, of thousands of skins, wings, and insect armor. There was not a scrap of dirt of any kind which had not been gathered into one of the two piles. The nest was nine feet above the floor, a distance (magnifying ant height to our own) of nearly a mile, and yet the care lavished on the cleanliness of the earth so far below was as thorough and well done as the actual provisioning of the colony.
As I watched the columns and the swarm-nest hour after hour, several things impressed me;—the absolute silence in which the ants worked;—such ceaseless activity without sound one associates only with a cinema film; all around me was tremendous energy, marvelous feats of achievement, super-human instincts, the ceaseless movement of tens of thousands of legionaries; yet no tramp of feet, no shouts, no curses, nowelcomes, no chanties. It was uncanny to think of a race of creatures such as these, dreaded by every living being, wholly dominant in their continent-wide sphere of action, yet born, living out their lives, and dying, dumb and blind, with no possibility of comment on life and its fullness, of censure or of applause.
The sweeping squad on the floor was interesting because of its limited field of work at such a distance from the nest; but close to my chair were a number of other specialized zones of activity, any one of which would have afforded a fertile field for concentrated study. Beneath the swarm on the white canvas, I noticed two large spots of dirt and moisture, where very small flies were collected. An examination showed that this was a second, nearer dumping-ground for all the garbage and refuse of the swarm which could not be thrown down on the kitchen middens far below. And here were tiny flies and other insects acting as scavengers, just as the hosts of vultures gather about the slaughter-house of Georgetown.
The most interesting of all the phases of life of the ants' home town, were those on the horizontal board which projected from the beam and stretched for several feet to one side of theswarm. This platform was almost on a level with my eyes, and by leaning slightly forward on the chair, I was as close as I dared go. Here many ants came from the incoming columns, and others were constantly arriving from the nest itself. It was here that I realized my good fortune and the achievement of my desires, when I first saw an army ant at rest. One of the first arrivals after I had squatted to my post, was a big soldier with a heavy load of roach meat. Instead of keeping on straight up the post, he turned abruptly and dropped his load. It was instantly picked up by two smaller workers and carried on and upward toward the nest. Two other big fellows arrived in quick succession, one with a load which he relinquished to a drogher-in-waiting. Then the three weary warriors stretched their legs one after another and commenced to clean their antennæ. This lasted only for a moment, for three or four tiny ants rushed at each of the larger ones and began as thorough a cleaning as masseurs or Turkish-bath attendants. The three arrivals were at once hustled away to a distant part of the board and there cleaned from end to end. I found that the focal length of my 8-diameter lens was justout of reach of the ants, so I focused carefully on one of the soldiers and watched the entire process. The small ants scrubbed and scraped him with their jaws, licking him and removing every particle of dirt. One even crawled under him and worked away at his upper leg-joints, for all the world as a mechanic will creep under a car. Finally, I was delighted to see him do what no car ever does, turn completely over and lie quietly on his back with his legs in air, while his diminutive helpers overran him and gradually got him into shape for future battles and foraging expeditions.
On this resting-stage, within well-defined limits, were dozens of groups of two cleaning one another, and less numerous parties of the tiny professionals working their hearts out on battle-worn soldiers. It became more and more apparent that in the creed of the army ants, cleanliness comes next to military effectiveness.
Here and there I saw independent individuals cleaning themselves and going through the most un-ant-like movements. They scraped their jaws along the board, pushing forward like a dog trying to get rid of his muzzle; then they turned on one side and passed the opposite legs againand again through the mandibles; while the last performance was to turn over on their backs and roll from side to side, exactly as a horse or donkey loves to do.
One ant, I remember, seemed to have something seriously wrong. It sat up on its bent-under abdomen in a most comical fashion, and was the object of solicitude of every passing ant. Sometimes there were thirty in a dense group, pushing and jostling; and, like most of our city crowds, many seemed to stop only long enough to have a moment's morbid sight, or to ask some silly question as to the trouble, then to hurry on. Others remained, and licked and twiddled him with their antennæ for a long time. He was in this position for at least twenty minutes. My curiosity was so aroused that I gathered him up in a vial, whereat he became wildly excited and promptly regained full use of his legs and faculties. Later, when I examined him under the lens, I could find nothing whatever wrong.
Off at one side of the general cleaning and reconstruction areas was a pitiful assemblage of cripples which had had enough energy to crawl back, but which did not attempt, or were not allowed, to enter the nest proper. Some hadone or two legs gone, others had lost an antenna or had an injured body. They seemed not to know what to do—wandering around, now and then giving one another a half-hearted lick. In the midst was one which had died, and two others, each badly injured, were trying to tug the body along to the edge of the board. This they succeeded in doing after a long series of efforts, and down and down fell the dead ant. It was promptly picked up by several kitchen-middenites and unceremoniously thrown on the pile of nest-débris. A load of booty had been dumped among the cripples, and as each wandered close to it, he seemed to regain strength for a moment, picked up the load, and then dropped it. The sight of that which symbolized almost all their life-activity aroused them to a momentary forgetfulness of their disabilities. There was no longer any place for them in the home or in the columns of the legionaries. They had been court-martialed under the most implacable, the most impartial law in the world—the survival of the fit, the elimination of the unfit.
The time came when we had to get at our stored supplies, over which the army ants were such an effective guard. I experimented on arunning column with a spray of ammonia and found that it created merely temporary inconvenience, the ants running back and forming a new trail. Formaline was more effective, so I sprayed the nest-swarm with a fifty-per-cent solution, strong enough, one would think, to harden the very boards. It certainly created a terrible commotion, and strings of the ants, two feet long, hung dangling from the nest. The heart of the colony came into view, with thousands of eggs and larvæ, looking like heaps of white rice-grains. Every ant seized one or the other and sought escape by the nearest way, while the soldiers still defied the world. The gradual disintegration revealed an interior meshed like a wasp's nest, chambered and honeycombed with living tubes and walls. Little by little the taut guy-ropes, lathes, braces, joists, all sagged and melted together, each cell-wall becoming dynamic, now expanding, now contracting; the ceilings vibrant with waving legs, the floors a seething mass of jaws and antennæ. By the time it was dark, the swarm was dropping in sections to the floor.
On the following morning new surprises awaited me. The great mass of the ants had moved in the night, vanishing with every egg andimmature larva; but there was left in the corner of the flat board a swarm of about one-quarter of the entire number, enshrouding a host of older larvæ. The cleaning zones, the cripples' gathering-room, all had given way to new activities, on the flat board, down near the kitchen middens, and in every horizontal crack.
The cause of all this strange excitement, this braving of the terrible dangers of fumes which had threatened to destroy the entire colony the night before, suddenly was made plain as I watched. A critical time was at hand in the lives of the all-precious larvæ, when they could not be moved—the period of spinning, of beginning the transformation from larvæ to pupæ. This evidently was an operation which had to take place outside the nest and demanded some sort of light covering. On the flat board were several thousand ants and a dozen or more groups of full-grown larvæ. Workers of all sizes were searching everywhere for some covering for the tender immature creatures. They had chewed up all available loose splinters of wood, and near the rotten, termite-eaten ends, the sound of dozens of jaws gnawing all at once was plainly audible. This unaccustomed, unmilitary labor produceda quantity of fine sawdust, which was sprinkled over the larvæ. I had made a partition of a bit of a British officer's tent which I had used in India and China, made of several layers of colored canvas and cloth. The ants found a loose end of this, teased it out and unraveled it, so that all the larvæ near by were blanketed with a gay, parti-colored covering of fuzz.
All this strange work was hurried and carried on under great excitement. The scores of big soldiers on guard appeared rather ill at ease, as if they had wandered by mistake into the wrong department. They sauntered about, bumped into larvæ, turned and fled. A constant stream of workers from the nest brought hundreds more larvæ; and no sooner had they been planted and débris of sorts sifted over them, than they began spinning. A few had already swathed themselves in cocoons—exceedingly thin coverings of pinkish silk. As this took place out of the nest,—in the jungle they must be covered with wood and leaves. The vital necessity for this was not apparent, for none of this débris was incorporated into the silk of the cocoons, which were clean and homogeneous. Yet the hundreds of ants gnawed and tore and laboredto gather this little dust, as if their very lives depended upon it.
With my hand-lens focused just beyond mandible reach of the biggest soldier, I leaned forward from my insulated chair, hovering like a great astral eye looking down at this marvelously important business of little lives. Here were thousands of army ants, not killing, not carrying booty, nor even suspended quiescent as organic molecules in the structure of the home, yet in feverish activity equaled only by battle, making ready for the great change of their foster offspring. I watched the very first thread of silk drawn between the larva and the outside world, and in an incredibly short time the cocoon was outlined in a tissue-thin, transparent aura, within which the tenant could be seen skilfully weaving its own shroud.
When first brought from the nest, the larvæ lay quite straight and still; but almost at once they bent far over in the spinning position. Then some officious worker would come along, and the unfortunate larva would be snatched up, carried off, and jammed down in some neighboring empty space, like a bolt of cloth rearranged upon a shelf. Then another ant would approach, antennæ the larva, disapprove, and again shift its position. It was a real survival of the lucky, as to who should avoid being exhausted by kindness and over-solicitude. I uttered many a chuckle at the half-ensilked unfortunates being toted about like mummies, and occasionally giving a sturdy, impatient kick which upset their tormentors and for a moment created a little swirl of mild excitement.
There was no order of packing. The larvæ were fitted together anyway, and meagerly covered with dust of wood and shreds of cloth. One big tissue of wood nearly an inch square was too great a temptation to be let alone, and during the course of my observation it covered in turn almost every group of larvæ in sight, ending by being accidentally shunted over the edge and killing a worker near the kitchen middens. There was only a single layer of larvæ; in no case were they piled up, and when the platform became crowded, a new column was formed and hundreds taken outside. To the casual eye there was no difference between these legionaries and a column bringing in booty of insects, eggs, and pupæ; yet here all was solicitude, never a bite too severe, or a blunder of undue force.
The sights I saw in this second day's accessible nest-swarm would warrant a season's meditation and study, but one thing impressed me above all others. Sometimes, when I carefully pried open one section and looked deep within, I could see large chambers with the larvæ in piles, besides being held in the mandibles of the components of the walls and ceilings. Now and then a curious little ghost-like form would flit across the chamber, coming to rest, gnome-like, on larva or ant. Again and again I saw these little springtails skip through the very scimitar mandibles of a soldier, while the workers paid no attention to them. I wondered if they were not quite odorless, intangible to the ants, invisible guests which lived close to them, going where, doing what they willed, yet never perceived by the thousands of inhabitants. They seemed to live in a kind of fourth dimensional state, a realm comparable to that which we people with ghosts and spirits. It was a most uncanny, altogether absorbing, intensely interesting relationship; and sometimes, when I ponder on some general aspect of the great jungle,—a forest of greenheart, a mighty rushing river, a crashing, blasting thunderstorm,—my mind suddenlyreverts by way of contrast to the tiny ghosts of springtails flitting silently among the terrible living chambers of the army ants.
On the following morning I expected to achieve still greater intimacy in the lives of the mummy soldier embryos; but at dawn every trace of nesting swarm, larvæ, pupæ and soldiers was gone. A few dead workers were being already carried off by small ants which never would have dared approach them in life. A big blue morpho butterfly flapped slowly past out of the jungle, and in its wake came the distant notes—high and sharp—of the white-fronted antbirds; and I knew that the legionaries were again abroad, radiating on their silent, dynamic paths of life from some new temporary nest deep in the jungle.
A jungle moon first showed me my beach. For a week I had looked at it in blazing sunlight, walked across it, even sat on it in the intervals of getting wonted to the new laboratory; yet I had not perceived it. Colonel Roosevelt once said to me that he would rather perceive things from the point of view of a field-mouse, than be a human being and merely see them. And in my case it was when I could no longer see the beach that I began to discern its significance.
This British Guiana beach, just in front of my Kartabo bungalow, was remarkably diversified, and in a few steps, or strokes of a paddle, I could pass from clean sand to mangroves and muckamucka swamp, thence to out-jutting rocks, and on to the Edge of the World, all within a distance of a hundred yards. For a time my beach walks resulted in inarticulate reaction. After months in the blindfolded canyons of New York's streets, a hemicircle of horizon, a hemisphere ofsky, and a vast expanse of open water lent itself neither to calm appraisal nor to impromptu cuff-notes.
It was recalled to my mind that the miracle of sunrise occurred every morning, and was not a rather belated alternation of illumination, following the quenching of Broadway's lights. And the moon I found was as dependable as when I timed my Himalayan expeditions by her shadowings. To these phenomena I soon became re-accustomed, and could watch a bird or outwit an insect in the face of a foreglow and silent burst of flame that shamed all the barrages ever laid down. But cosmic happenings kept drawing my attention and paralyzing my activities for long afterward. With a double rainbow and four storms in action at once; or a wall of rain like sawn steel slowly drawing up one river while the Mazaruni remains in full sunlight; with Pegasus galloping toward the zenith at midnight and the Pleiades just clearing the Penal Settlement, I could not always keep on dissecting, or recording, or verifying the erroneousness of one of my recently formed theories.
There was Thuban, gazing steadily upon my little mahogany bungalow, as, six millenniumsago, he had shone unfalteringly down the little stone tube that led his rays into the Queen's Chamber, in the very heart of great Cheops. Just clearing a low palm was the present North Star, while, high above, Vega shone, patiently waiting to take her place half a million years hence. When beginning her nightly climb, Vega drew a thin, trembling thread of argent over the still water, just as in other years she had laid for me a slender silver strand of wire across frozen snow, and on one memorable night traced the ghost of a reflection over damp sand near the Nile—pale as the wraiths of the early Pharaohs.
Low on the eastern horizon, straight outward from my beach, was the beginning and end of the great zodiac band—the golden Hamal of Aries and the paired stars of Pisces; and behind, over the black jungle, glowed the Southern Cross. But night after night, as I watched on the beach, the sight which moved me most was the dull speck of emerald mist, a merest smudge on the slate of the heavens,—the spiral nebula in Andromeda,—a universe in the making, of a size unthinkable to human minds.
The power of my jungle beach to attract andhold attention was not only direct and sensory,—through sight and sound and scent,—but often indirect, seemingly by occult means. Time after time, on an impulse, I followed some casual line of thought and action, and found myself at last on or near the beach, on a lead that eventually would take me to the verge or into the water.
Once I did what for me was a most unusual thing. I woke in the middle of the night without apparent reason. The moonlight was pouring in a white flood through the bamboos, and the jungle was breathless and silent. Through my window I could see Jennie, our pet monkey, lying aloft, asleep on her little verandah, head cushioned on both hands, tail curled around her dangling chain, as a spider guards her web-strands for hint of disturbing vibrations. I knew that the slightest touch on that chain would awaken her, and indeed it seemed as if the very thought of it had been enough; for she opened her eyes, sent me the highest of insect-like notes and turned over, pushing her head within the shadow of her little house. I wondered if animals, too, were, like the Malays and so many savage tribes, afraid of the moonlight—the "luna-cy" danger in those strange color-strainedrays, whose power must be greater than we realize. Beyond the monkey roosted Robert, the great macaw, wide-awake, watching me with all that broadside of intensive gaze of which only a parrot is capable.
The three of us seemed to be the only living things in the world, and for a long time we—monkey, macaw, and man—listened. Then all but the man became uneasy. The monkey raised herself and listened, uncurled her tail, shifted, and listened. The macaw drew himself up, feathers close, forgot me, and listened. They, unlike me, were not merely listening—they were hearing something. Then there came, very slowly and deliberately, as if reluctant to break through the silent moonlight, a sound, low and constant, impossible to identify, but clearly audible even to my ears. For just an instant longer it held, sustained and quivering, then swiftly rose into a crashing roar—the sound of a great tree falling. I sat up and heard the whole long descent; but at the end, after the moment of silence, there was no deep boom—the sound of the mighty bole striking and rebounding from the earth itself. I wondered about this for a while; then the monkey and I went to sleep, leaving the macawalone conscious in the moonlight, watching through the night with his great round, yellow orbs, and thinking the thoughts that macaws always think in the moonlight.
The next day the macaw and the monkey had forgotten all about the midnight sound, but I searched and found why there was no final boom. And my search ended at my beach. A bit of overhanging bank had given way and a tall tree had fallen headlong into the water, its roots sprawling helplessly in mid-air. Like rats deserting a sinking ship, a whole Noah's ark of tree-living creatures was hastening along a single cable shorewards: tree-crickets; ants laden with eggs and larvæ; mantids gesticulating as they walked, like old men who mumble to themselves; wood-roaches, some green and leaf-like, others, facsimiles of trilobites—but fleet of foot and with one goal.
What was a catastrophe for a tree and a shift of home for the tenants was good fortune for me, and I walked easily out along the trunk and branches and examined the strange parasitic growths and the homes which were being so rapidly deserted. The tide came up and covered the lower half of the prostrate tree, drowning whatcreatures had not made their escape and quickening the air-plants with a false rain, which in course of time would rot their very hearts.
But the first few days were only the overture of changes in this shift of conditions. Tropic vegetation is so tenacious of life that it struggles and adapts itself with all the cunning of a Japanese wrestler. We cut saplings and thrust them into mud or the crevices of rocks at low tide far from shore, to mark our channel, and before long we have buoys of foliage banners waving from the bare poles above water. We erect a tall bamboo flagpole on the bank, and before long our flag is almost hidden by the sprouting leaves, and the pulley so blocked that we have occasionally to lower and lop it.
So the fallen tree, still gripping the nutritious bank with a moiety of roots, turned slowly in its fibrous stiffness and directed its life and sap and hopes upward. During the succeeding weeks I watched trunk and branches swell and bud out new trunks, new branches, guided, controlled, by gravity, light, and warmth; and just beyond the reach of the tides, leaves sprouted, flowers opened and fruit ripened. Weeks after the last slow invertebrate plodder had made his escapeshorewards, the taut liana strand was again crowded with a mass of passing life—a maze of vines and creepers, whose tendrils and suckers reached and curled and pressed onward, fighting for gangway to shore, through days and weeks, as the animal life which preceded them had made the most of seconds and minutes.
The half-circle of exposed raw bank became in its turn the center of a myriad activities. Great green kingfishers began at once to burrow; tiny emerald ones chose softer places up among the wreckage of wrenched roots; wasps came and chopped out bits for the walls and partitions of their cells; spiders hung their cobwebs between ratlines of rootlets; and hummingbirds promptly followed and plucked them from their silken nets, and then took the nets to bind their own tiny air-castles. Finally, other interests intervened, and like Jennie and Robert, I gradually forgot the tree that fell without an echo.
In the jungle no action or organism is separate, or quite apart, and this thing which came to the three of us suddenly at midnight led by devious means to another magic phase of the shore.
A little to the south along my beach is the Edge of the World. At least, it looks very much as I have always imagined that place must look, and I have never been beyond it; so that, after listening to many arguments in courts of law, and hearing the reasoning of bolsheviki, teetotalers, and pacifists, I feel that I am quite reasonable as human beings go. And best of all, it hurts no one, and annoys only a few of my scientific friends, who feel that one cannot indulge in such ideas at the wonderful hour of twilight, and yet at eight o'clock the following morning describe with impeccable accuracy the bronchial semi-rings, and the intricate mosaic of cartilage which characterizes and supports themembranis tympaniformisofAttila thamnophiloides; a dogma which halves life and its interests.
The Edge of the World has always meant a place where usual things are different; and my southern stretch of beach was that, because of roots. Whenever in digging I have come across a root and seen its living flesh, perhaps pink or rose or pale green, so far underground, I have desired to know roots better; and now I found my opportunity. I walked along the proper trail, through right and usual trees,with reasonable foliage and normal trunks, and suddenly I stepped down over the Edge. Overhead and all around there was still the foliage. It shut out the sun except for greenish, moderated spots and beams. The branches dipped low in front over the water, shutting out the sky except along the tops of the cross-river jungle. Thus a great green-roofed chamber was formed; and here, between jungle and the water-level of the world, was the Kingdom of the Roots.
Great trees had in their youth fallen far forward, undermined by the water, then slowly taken a new reach upward and stretched forth great feet and hands of roots, palms pressing against the mud, curved backs and thews of shoulders braced against one another and the drag of the tides. Little by little the old prostrate trunks were entirely obliterated by this fantastic network. There were no fine fibers or rootlets here; only great beams and buttresses, bridges and up-ended spirals, grown together or spreading wide apart. Root merged with trunk, and great boles became roots and then boles again in this unreasonable land. For here, in place of damp, black mold and soil, water alternated with dark-shadowed air; and so I was able for a timeto live the life of a root, resting quietly among them, watching and feeling them, and moving very slowly, with no thought of time, as roots must.
I liked to wait until the last ripple had lapped against the sand beneath, and then slip quietly in from the margin of the jungle and perch—like a great tree-frog—on some convenient shelf. Seumas and Brigid would have enjoyed it, in spite of the fact that the Leprechauns seemed to have just gone. I found myself usually in a little room, walled with high-arched, thin sheets of living roots, some of which would form solid planks three feet wide and twelve long, and only an inch or two in thickness. These were always on edge, and might be smooth and sheer, or suddenly sprout five stubby, mittened fingers, or pairs of curved and galloping legs—and this thought gave substance to the simile which had occurred again and again: these trees reminded me of centaurs with proud, upright man torsos, and great curved backs. In one, a root dropped down and rested on the back, as a centaur who turns might rest his hand on his withers.
When I chanced upon an easy perch, and a stray idea came to mind, I squatted or sat orsprawled, and wrote, and strange things often happened to me. Once, while writing rapidly on a small sheet of paper, I found my lines growing closer and closer together until my fingers cramped, and the consciousness of the change overlaid the thoughts that were driving hand and pen. I then realized that, without thinking, I had been following a succession of faint lines, cross-ruled on my white paper, and looking up, I saw that a leaf-filtered opening had reflected strands of a spider-web just above my head, and I had been adapting my lines to the narrow spaces, my chirography controlled by cobweb shadows.
The first unreality of the roots was their rigidity. I stepped from one slender tendon of wood to the next, expecting a bending which never occurred. They might have been turned to stone, and even little twigs resting on the bark often proved to have grown fast. And this was the more unexpected because of the grace of curve and line, fold upon fold, with no sharp angles, but as full of charm of contour as their grays and olives were harmonious in color. Photographs showed a little of this; sketches revealed more; but the great splendid things themselves, devoidof similes and human imagination, were soul-satisfying in their simplicity.
I seldom sat in one spot more than a few minutes, but climbed and shifted, tried new seats, couches, perches, grips, sprawling out along the tops of two parallel monsters, or slipping under their bellies, always finding some easy way to swing up again. Two openings just permitted me to squeeze through, and I wondered whether, in another year, or ten, or fifty, the holes would have grown smaller. I became imbued with the quiet joy of these roots, so that I hated to touch the ground. Once I stepped down on the beach after something I had dropped, and the soft yielding of the sand was so unpleasant that I did not afterwards leave this strange mid-zone until I had to return. Unlike Antæus, I seemed to gain strength and poise by disassociation with the earth.
Here and there were pockets in the folds of the sweeping draperies, and each pocket was worth picking. When one tried to paint the roots, these pockets seemed made expressly to take the place of palette cups, except that now and then a crab resented the infusion of Hooker's green with his Vandyke brown puddle, and seizedthe end of the brush. The crabs were worthy tenants of such strange architecture, with comical eyes twiddling on the end of their stalks, and their white-mittened fists feinting and threatening as I looked into their little dark rain or tide-pools.
I found three pockets on one wall, which seemed as if they must have been "salted" for my benefit; and in them, as elsewhere on my beach, the two extremes of life met. The topmost one, curiously enough, contained a small crab, together with a large water-beetle at the farther end. Both seemed rather self-conscious, and there was no hint of fraternizing. The beetle seemed to be merely existing until darkness, when he could fly to more water and better company; and the crab appeared to be waiting for the beetle to go.
The next pocket was a long, narrow, horizontal fold, and I hoped to find real excitement among its aquatic folk; but to my surprise it had no bottom, but was a deep chute or socket, opening far below to the sand. However, this was not my discovery, and I saw dimly a weird little head looking up at me—a gecko lizard, which called this crevice home and the crabs neighbors. Ihailed him as the only other backboned friend who shared the root-world with me, and then listened to a high, sweet tone, which came forth in swinging rhythm. It took some time for my eyes to become accustomed to the semi-darkness, and then I saw what the gecko saw—a big yellow-bodied fly humming in this cavern, and swinging in a small orbit as she sang. Now and then she dashed out past me and hovered in mid-air, when her note sank to a low, dull hum. Back again, and the sound rose and fell, and gained ten times in volume from the echo or reverberations. Each time she passed, the little lizard licked his chops and swallowed—a sort of vicarious expression of faith or desire; or was he in a Christian Science frame of mind, saying, "My, how good that fly tasted!" each time the dipteron passed? The fly was just as inexplicable, braving danger and darkness time after time, to leave the sunshine and vibrate in the dusk to the enormously magnified song of its wings.
With eyes that had forgotten the outside light, I leaned close to the opening and rested my forehead against the lichens of the wall of wood. The fly was frightened away, the gecko slipped lower, seemingly without effort, and in a hollowedside of the cavernous root I saw a mist, a quivering, so tenuous and indistinct that at first it might have been the dancing of motes. I saw that they were living creatures—the most delicate of tiny crane-flies—at rest looking like long-legged mosquitoes. Deep within this root, farther from the light than even the singing fly had ventured, these tiny beings whirled madly in mid-air—subterranean dervishes, using up energy for their own inexplicable ends, of which one very interested naturalist could make nothing.
Three weeks afterward I happened to pass at high tide in the canoe and peered into this pocket. The gecko was where geckos go in the space of three weeks, and the fly also had vanished, either within or without the gecko. But the crane-flies were still there: to my roughly appraising eyes the same flies, doing the same dance in exactly the same place. Three weeks later, and again I returned, this time intentionally, to see whether the dance still continued; and it was in full swing. That same night at midnight I climbed down, flashed a light upon them, and there they whirled and vibrated, silently, incredibly rapid, unceasingly.
After a thousand hours all the surroundings had changed. New leaves had sprouted, flowers faded and turned to fruit, the moon had twice attained her full brightness, our earth and sun and the whole solar system had swept headlong a full two-score million miles on the endless swing toward Vega. Only the roots and the crane-flies remained. A thousand hours had apparently made no difference to them. The roots might have been the granite near by, fashioned by primeval earth-flame, and the flies but vibrating atoms within the granite, made visible by some alchemy of elements in this weird Rim of the World.
And so a new memory is mine; and when one of these insects comes to my lamp in whatever part of the world, fluttering weakly, legs breaking off at the slightest touch, I shall cease to worry about the scientific problems that loom too great for my brain, or about the imperfection of whatever I am doing, and shall welcome the crane-fly and strive to free him from this fatal passion for flame, directing him again into the night; for he may be looking for a dark pocket in a root, a pocket on the Edge of the World, where crane-flies may vibrate with their fellowsin an eternal dance. And so, in some ordained way, he will fulfil his destiny and I acquire merit.
To write of sunrises and moonlight is to commit literary harikiri; but as that terminates life, so may I end this. And I choose the morning and the midnight of the sixth of August, for reasons both greater and less than cosmic. Early that morning, looking out from the beach over the Mazacuni, as we called the union of the two great rivers, there was wind, yet no wind, as the sun prepared to lift above the horizon. The great soft-walled jungle was clear and distinct. Every reed at the landing had its unbroken counterpart in the still surface. But at the apex of the waters, the smoke of all the battles in the world had gathered, and upon this the sun slowly concentrated his powers, until he tore apart the cloak of mist, turning the dark surface, first to oxidized, and then to shining quicksilver. Instantaneously the same shaft of light touched the tips of the highest trees, and as if in response to a poised bâton, there broke forth that wonder of the world—the Zoroastrian chorus of tens of thousands of jungle creatures.
Over the quicksilver surface little individualbreezes wandered here and there. I could clearly see the beginning and the end of them, and one that drifted ashore and passed me felt like the lightest touch of a breath. One saw only the ripple on the water; one thought of invisible wings and trailing unseen robes.
With the increasing warmth the water-mist rose slowly, like a last quiet breath of night; and as it ascended,—the edges changing from silvery gray to grayish white,—it gathered close its shredded margins, grew smaller as it rose higher, and finally became a cloud. I watched it and wondered about its fate. Before the day was past, it might darken in its might, hurl forth thunders and jagged light, and lose its very substance in down-poured liquid. Or, after drifting idly high in air, the still-born cloud might garb itself in rich purple and gold for the pageant of the west, and again descend to brood over the coming marvel of another sunrise.
The tallest of bamboos lean over our low, lazy spread of bungalow; and late this very night, in the full moonlight, I leave my cot and walk down to the beach over a shadow carpet of Japanese filigree. The air over the white sand is as quiet and feelingless to my skin as complete, comfortableclothing. On one side is the dark river; on the other, the darker jungle full of gentle rustlings, low, velvety breaths of sound; and I slip into the water and swim out, out, out. Then I turn over and float along with the almost tangible moonlight flooding down on face and water. Suddenly the whole air is broken by the chorus of big red baboons, which rolls and tumbles toward me in masses of sound along the surface and goes trembling, echoing on over shore and jungle, till hurled back by the answering chorus of another clan. It stirs one to the marrow, for there is far more in it than the mere roaring of monkeys; and I turn uneasily, and slowly surge back toward the sand, overhand now, making companionable splashes.
And then again I stop, treading water softly, with face alone between river and sky; for the monkeys have ceased, and very faint and low, but blended in wonderful minor harmony, comes another chorus—from three miles down the river: the convicts singing hymns in their cells at midnight. And I ground gently and sit in the silvered shadows with little bewildered shrimps flicking against me, and unlanguaged thoughts come and go—impossible similes, too poignantphrases to be stopped and fettered with words, and I am neither scientist nor man nor naked organism, but just mind. With the coming of silence I look around and again consciously take in the scene. I am very glad to be alive, and to know that the possible dangers of jungle and water have not kept me armed and indoors. I feel, somehow, as if my very daring and gentle slipping-off of all signs of dominance and protection on entering into this realm had made friends of all the rare but possible serpents and scorpions, sting-rays and perai, vampires and electric eels. For a while I know the happiness of Mowgli.
And I think of people who would live more joyful lives in dense communities, who would be more tolerant, and more certain of straightforward friendship, if they could have as a background a fundamental hour of living such as this, a leaven for the rest of what, in comparison, seems mere existence.
At last I go back between the bamboos and their shadows, from unreal reality into a definiteness of cot and pajamas and electric torch. But wild nature still keeps touch with me; for as I write these lines, curled up on the edge of thecot, two vampires hawk back and forth so close that the wind from their wings dries my ink. And the soundness of my sleep is such that time does not exist between their last crepuscular squeak and the first wiry twittering of a blue tanager, in full sunshine, from a palm overhanging my beach.
