Together with the pure artistic joy which was stirred at the sight of

these tiny ornate globes, there was aroused a realization of

complexity, of helpless, ignorant achievement; the butterfly blindly

pausing in her flower-to-flower fluttering--a pause as momentous to

her race as that of the slow daily and monthly progress of the weed's

struggle to fruition.

I took a final glance at the eggs before returning to my own larger

world, and I detected a new complication, one which left me with

feelings too involved for calm scientific contemplation. As if a

Martian should suddenly become visible to an astronomer, I found that

one of the egg planets was inhabited. Perched upon the summit--quite

near the north pole--was an insect, a wasp, much smaller than the egg

itself. And as I looked, I saw it at the climax of its diminutive

life; for it reared up, resting on the tips of two legs and the

iridescent wings, and sunk its ovipositor deep into the crystalline

surface. As I watched, an egg was deposited, about the latitude of New

York, and with a tremor the tiny wasp withdrew its instrument and

rested.

On the same leaf were casually blown specks of dust, larger than the

quartette of eggs. To the plant the cluster weighed nothing, meant

nothing more than the dust. Yet a moment before they contained the

latent power of great harm to the future growth of the weed--four

lusty caterpillars would work from leaf to leaf with a rapidity and

destructiveness which might, even at the last, have sapped the

maturing seeds. Now, on a smaller scale, but still within the realm of

insect life, all was changed--the plant was safe once more and no

caterpillars would emerge. For the wasp went from sphere to sphere and

inoculated every one with the promise of its kind. The plant bent

slightly in a breath of wind, and knew nothing; the butterfly was far

away to my left, deep-drinking in a cluster of yellow cassia; the wasp

had already forgotten its achievement, and I alone--an outsider, an

interloper--observed, correlated, realized, appreciated, and--at the

last--remained as completely ignorant as the actors themselves of the

real driving force, of the certain beginning, of the inevitable end.

Only a momentary cross-section was vouchsafed, and a wonder and a

desire to know fanned a little hotter.

I had far from finished with my weed: for besides the cuts and tears

and disfigurements of the leaves, I saw a score or more of curious

berry-like or acorn-like growths, springing from both leaf and stem. I

knew, of course, that they were insect-galls, but never before had

they meant quite so much, or fitted in so well as a significant

phenomenon in the nexus of entangling relationships between the weed

and its environment. This visitor, also a minute wasp of sorts,

neither bit nor cut the leaves, but quietly slipped a tiny egg here

and there into the leaf-tissue.

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 cluster 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 competitors: 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 fashioned 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-glass 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 shifted 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 shells 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

passport 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 scraping 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 glasses 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 shell 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 butterfly

dazzles the eyes with a final flash of his blazing azure before

vanishing 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 passed 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 passed 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 analyzed 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 passage 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 relationship 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

butterflies, 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 passing 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, breasts 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 assemblage 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 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 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 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 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 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 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 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 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.
