Instinctively we rose on the instant, just in time to see a jaguar swerve off on one side and disappear in a swish of swaying reed stems. I have never known one of these animals to attack a man, and in this case the jaguar had undoubtedly heard but not scented us, and the attack ceased the moment we proved to be other than deer or similar prey. The incident had come and pa.s.sed too swiftly for thought, but now when we realized that this was a bit of the real wild life of the jungle, our enthusiasm never flagged, and we kept steadily at the heart-breaking work, resting only now and then for our cuts to heal.
Then a government official who was our guest, took pity on us, and for science" sake, obtained special dispensation. One morning we went out and found in our compound several huge, blue-uniformed policemen, who saluted and with real black magic, produced twenty convicts--negroes and coolies--armed with cutla.s.ses. So began the second phase of what we now named the Convict Trail. We had already fought our painful way through a half-mile of the terrible maze, and now we heartily welcomed this new aid, whether good-natured murderers, and burglars, or like Sippy, Slorg and Slith, mere thieves. We watched them strip to their black skins and begin a real a.s.sault. On a front of ten to fifteen feet, the tangle fairly dissolved before our eyes, and their great tough palms and soles made little moment of the razor-gra.s.s and thorns. In one of the slight-bodied coolies, whose task was to clear away the cut debris, I recognized Ram Narine, whose trial had been the cause of my traveling another trail.
With my friend, Hope, an honest forger, I went on far ahead and laid the course for the jungle. In especially dense parts we climbed to the summit of great jungle stumps and stretched a white sheet to guide the oncoming trail cutters.
Day after day the score of convicts returned with their guards and at last we saw the path unite with an old game and Indian trail in the cool shade of the jungle, and Kalac.o.o.n was in direct contact with the great tropical forest itself. I have pa.s.sed lightly over the really frightful pain and exhaustion which we experienced in the initial part of this work, and which emphasized the tremendous difference between the age-old jungle untouched by man, and the terrible tangle which springs after he has destroyed the primeval vegetation.
After this came our reward, and never a day pa.s.sed but the trail yielded many wonderful facts. The creatures of the wilderness soon found this wide swath, and used it by day and night, making it an exciting thing for us to peer around a corner, to see what strange beings were sitting or feeding in our little street.
Before the trail was quite completed, it yielded one of the most exciting hunts of our trip--the noosing of a giant bushmaster--the most deadly serpent of the tropics. Nupee--my Akawai Indian hunter, two nestling trogons and Easter eve--these things led to the capture of the Master of the Bush: For nothing in the tropics is direct, premeditated.
My thoughts were far from poisonous serpents when Nupee came into our Kalac.o.o.n laboratory late on a Sat.u.r.day afternoon. Outdoors he had deposited the coa.r.s.er game intended for the mess, consisting, today, of a small deer, a tinamou or maam and two agoutis. But now with his quiet smile, he held out his lesser booty, which he always brought in to me, offering in his slender, effeminate hands his contribution to science.
Usually this was a bird of brilliant plumage, or a nestful of maam"s eggs with sh.e.l.ls like great spheres of burnished emeralds. These he would carry in a basket so cunningly woven from a single palm frond that it shared our interest in its contents. Today, he presented two nestling trogons, and this was against rules. For we desired only to know where such nests were, there to go and study and photograph.
"Nupee,--listen! You sabe we no want bird here. Must go and show nest, eh?"
"Me sabe."
Accompanied by one of us, off he started again, without a murmur. In the slanting rays of the sun he walked lightly down the trail from Kalac.o.o.n as if he had not been hunting since early dawn. An hour pa.s.sed and the sun swung still lower when a panting voice gasped out:
"Huge labaria, yards long! Big as leg!"
The flight of queen bees and their swarms, the call to arms in a sleeping camp creates somewhat the commotion that the news of the bushmaster aroused with us. For he is really what his name implies. What the elephant is to the African jungles and the buffalo to Malaysia, this serpent is to the Guiana wilderness. He fears nothing--save one thing, hunting ants, before which all the world flees. And this was the first bushmaster of the rainy season.
Nupee had been left to mount guard over the serpent which had been found near the trogon tree. Already the light was failing; so we walked rapidly with gun, snake-pole and canvas bag. Parrakeets hurtled bamboowards to roost; doves scurried off and small rails flew from our path and flopped into the reeds. Our route led from the open compound of Kalac.o.o.n, through the freshly cut Convict Trail, toward the edge of the high bush, and we did not slacken speed until we were in the dim light which filtered through the western branches.
At the top of the slope we heard a yell--a veritable Red Indian yell--and there our Akawai hunter was dancing excitedly about, shouting to us to come on. "Snake, he move! Snake, he move!" We arrived panting, and he tremblingly led me along a fallen tree and pointed to the dead leaves. I well knew the color and pattern of the bushmaster. I had had them brought to me dead and had killed them myself, and I had seen them in their cage behind gla.s.s. But now, though I was thinking bushmaster and looking bushmaster, my eyes insisted on registering dead leaves.
Eager as I was to begin operations before darkness closed down, it was a full three minutes before I could honestly say, "This is leaf; that is snake."
The pattern and pigment of the cunningly arranged coils were that of the jungle floor, anywhere; a design of dead leaves, reddish-yellow, pinkish, dark-brown, etched with mold, fungus and decay, and with all the shadows and high lights which the heaped-up plant tissues throw upon one another. In the center of this dread plaque, this reptilian mirage, silent and motionless, rested the head. I knew it was triangular and flattened, because I had dissected such heads in times past, but now my senses revealed to me only an irregularity in the contour, a central focus in this jungle mat, the unraveling of which spelt death.
It was a big snake, seven or eight feet long, and heavy bodied--by no means a one-man job. Again we carefully examined the screw-eyes on the pole, and each looked behind for a possible line of escape.
I quickly formed my method of attack. Nupee was sent to cut forked sticks, but his enthusiasm at having work to do away from the scene of immediate conflict was so sincere that he vanished altogether and returned with the sticks only when our shouts announced the end of the struggle. An Indian will smilingly undergo any physical hardship, and he will face any creature in the jungle, except the bushmaster.
We approached from three sides, bringing snake-pole, free noose and gun to bear. Slowly the noose on the pole pushed nearer and nearer. I had no idea how he would react at the attack, whether he would receive it quietly, or, as I have seen the king cobra in Burma, become enraged and attack in turn.
The cord touched his nose, and he drew back close to some bushy stems.
Again it dangled against his head, and his tongue played like lightning.
And now he sent forth the warning of his mastership--a sharp _whirrrrr!_ and the tip of his tail became a blur, the rough scales rasping and vibrating against the dead leaves, and giving out a sound not less sharp and sinister than the instrumental rattling of his near relatives.
For a moment the head hung motionless, then the noose-man made a lunge and pulled his cord. The great serpent drew back like a flash, and turning, undulated slowly away toward the darker depths of the forest.
There was no panic, no fear of pursuit in his movements. He had encountered something quite new to his experience, and the knowledge of his own power made it easy for him to gauge that of an opponent. He feared neither deer nor tapir, yet at their approach he would sound his warning as a reciprocal precaution, poison against hoofs. And now, when his warning had no effect on this new disturbing thing, he chose dignifiedly to withdraw.
I crept quickly along on one side and with the gun-barrel slightly deflected his course so that he was headed toward an open s.p.a.ce, free from brush and bush-ropes. Here the pole-man awaited him, the noose spread and swaying a few inches from the leaves. Steadily the snake held to his course, and without sensing any danger pushed his head cleanly into the circle of cord. A sudden snap of the taut line and pandemonium began. The snake lashed and curled and whipped up a whirlpool of debris, while one of us held grimly on to the noose and the rest tried to disentangle the whirling coils and make certain of a tight grip close behind the head, praying for the screw-eyes to hold fast. Even with the scant inch of neck ahead of the noose, the head had such play that I had to pin it down with the gun-barrel before we dared seize it. When our fingers gained their safe hold and pressed, the great mouth opened wide, a gaping expanse of snowy white tissue, and the inch-long fangs appeared erect, each draped under the folds of its sheath like a rapier outlined beneath a courtier"s cloak.
When once the serpent felt himself conquered, he ceased to struggle; and this was fortunate, for in the dim light we stumbled more than once as we sidled and backed through the maze of lianas and over fallen logs.
Nupee now appeared, unashamed and wide-eyed with excitement. He followed and picked up the wreck of battle--gun, hats and bags which had been thrown aside or knocked off in the struggle. With locked step, so as not to wrench the long body, we marched back to Kalac.o.o.n. Now and then a great shudder would pa.s.s through the hanging loops and a spasm of muscular stress that tested our strength. It was no easy matter to hold the snake, for the scales on its back were as rough and hard as a file, and a sudden twist fairly took the skin off one"s hand.
I cleaned his mouth of all dirt and debris, and then we laid him upon the ground and, without stretching, found that he measured a good eight feet and a half. With no relaxing of care we slid him into the wired box which would be his home until he was liberated in his roomier quarters in the Zoological Park in New York.
Close to the very entrance of the Convict Trail behind Kalac.o.o.n stood four sentinel trees. Every day we pa.s.sed and repa.s.sed them on the way to and from the jungle. For many days we paid very little attention to them, except to be grateful for the shade cast by their dense foliage of glossy leaves. Their trunks were their most striking feature, the bark almost concealed by a maze of beautifully colored lichens, different forms overlapping one another in many places, forming a palimpsest of gray, white, pink, mauve and lilac. One day a streaked flycatcher chose the top of a branch for her nest, and this we watched and photographed and robbed for science" sake, and again we thought no more of the four trees.
Late in April, however, a change came over the trees. The leaves had been shed some time in January and the fallen foliage formed a dry ma.s.s on the ground which crackled under foot. Now each branch and twig began to send out cl.u.s.ters of small buds, and one day,--a week after Easter,--these burst into indescribable glory. Every lichened bough and branch and twig was lined with a soft ma.s.s of bloom, clear, bright cerise, which reflected its brilliance on the foliage itself. After two days a rain of stamens began and soon the ground beneath the trees was solid cerise, a carpet of tens of thousands of fallen stamens, and within the length of a foot on one small branch were often a score of blooms. This feast of color was wonderful enough, and it made us want to know more of these trees. But all the information we could glean was that they were called French cashew. Yet they had not nearly finished with the surprises they had in store. A hummingbird or two was not an uncommon sight along the trail at any time, but now we began to notice an increase in numbers. Then it was observed that the tiny birds seemed to focus their flight upon one part of the clearing, and this proved to be the four cashew trees.
The next few days made the trees ever memorable: they were the Mecca of all the hummingbirds in the jungle. In early morning the air for many yards resounded with a dull droning, as of a swarming of giant bees.
Standing or sitting under the tree we could detect the units of this host and then the individuals forced themselves on our notice. Back and forth the hummers swooped and swung, now poising in front of a ma.s.s of blossom and probing deeply among the stamens, now dashing off at a tangent, squeaking or chattering their loudest. The magnitude of the total sound made by these feathered atoms was astounding; piercing squeaks, shrill insect-like tones, and now and then a real song, diminutive trills and warbles as if from a flock of song birds a long distance away. Combats and encounters were frequent, some mere sparring bouts, while, when two would go at it in earnest, their humming and squeaks and throb of wings were audible above the general noise.
This being an effect, I looked for the cause. The ma.s.sed cerise bloom gave forth comparatively little perfume, but at the base of each flower, hidden and protected by the twenty score densely ranked stamens, was a cup of honey; not a nectary with one or two delicately distilled drops, but a good thimbleful, a veritable stein of liquor. No creature without a long proboscis or bill could penetrate the chevaux-de-frise of stamens, and to reach the honey the hummingbirds had to probe to their eyes. They came out with forehead well dusted with pollen and carried it to the next blossom. The destiny of the flower was now fulfilled, the pot of honey might dry up, the stamens rain to the earth and the glory of Tyrian rose pa.s.s into the dull hues of decay.
Day after day as we watched this kaleidoscope of vegetable and avian hues, we came to know more intimately the units which formed the ma.s.s.
There were at least fifteen species and all had peculiarities of flight and plumage so marked that they soon became recognizable at sight.
After our eyes had become accustomed to specific differences in these atoms of birds we began to notice the eccentricities of individuals.
This was made easy by the persistence with which certain birds usurped and clung to favorite perches. One glowing hermit clad in resplendent emerald armor selected a bare twig on a nearby shrub and from there challenged every hummer that came in sight; whether larger, smaller or of his own kind made no difference. He considered the cashew trees as his own special property and as far as his side of them went he made good his claim. I have never seen such a concentration of virile combative force in so condensed a form.
In some such way as vultures concentrate upon carrion, so news of the cashew sweets had pa.s.sed through the jungle. Not by any altruistic agency we may be certain, as we watch the selfish, irritable little beings, but by subtile scent, or as with the vultures, by the jealous watching of each other"s actions. I observed closely for one hour and counted one hundred and forty-six hummingbirds coming to the tree.
During the day at least one thousand must visit it.
They did not have a monopoly of the cashew manna, for now and then a honey-creeper or flower-p.e.c.k.e.r flew into the tree and took toll of the sweets. But they were scarcely noticeable. We had almost a pure culture of hummingbirds to watch and vainly to attempt to study, for more elusive creatures do not exist. Convict Trail revealed no more beautiful a sight than this concentration of the smallest, most active and the most gorgeous birds in the world.
Such treats--floral and avian--were all that might be expected of any tree, but the cashews had still more treasures in store. The weeks pa.s.sed and we had almost forgotten the flowers and hummingbirds, when a new odor greeted us, the sweet, intense smell of overripe fruit. We noticed a scattering of soft yellow cashews fallen here and there, and simultaneously there arrived the hosts of fruit-eating birds. From the most delicate turquoise honey-creepers to great red and black grosbeaks, they thronged the trees. All day a perfect stream of tanagers--green, azure and wine-colored--flew in and about the manna, callistes and silver-beaks, dacnis and palm tanagers. And for a whole week we gloried in this new feast of color, before the last riddled cashew dropped, to be henceforth the prize of great wasps and gauze-winged flies, who guzzled its fermented juice and helped in the general redistribution of its flesh--back to the elements of the tropic mold, to await the swarms of fingering rootlets, a renewed synthesis--to rise again for a time high in air, again to become part of blossom and bird and insect.
It was along this Convict Trail that I sank the series of pits which trapped unwary walkers of the night, and halfway out at pit number five, the army ants waged their wonderful warfare.
In fact it was while watching operations in another sector of this same battle-front that I found myself all unintentionally in the sleeping chamber of the heliconias.
Tired from a long day"s work in the laboratory, I wandered slowly along the Convict Trail, aimlessly, in that wholly relaxed state which always seems to invite small adventures. It is a mental condition wholly desirable, but not to be achieved consciously. One cannot say, "Lo, I will now be relaxed, receptive." It must come subconsciously, unnoticed, induced by a certain wearied content of body or mind--and then--many secret doors stand ajar, any one of which may be opened and pa.s.sed if the G.o.ds approve. My stroll was marked at first, however, by only one quaint happening. For several weeks the jolly little trail-lizards had been carrying on most enthusiastic courtships, marked with much bowing and posing, and a terrific amount of scrambling about. The previous day--that of the first rains--numbers of lizardlets appeared, and at the same time the brown tree-lizards initiated their season of love-making.
I had often watched them battle with one another--combats wholly futile as far as any damage was concerned. But the vanquished invariably gave up to his conqueror the last thing he had swallowed, the victor receiving it in a gluttonly rather than a gracious spirit, but allowing his captive to escape. I surprised one of these dark-brown chaps in the trail and seized him well up toward the head, to preserve his tail intact. Hardly had I lifted him from the ground, when he turned his head, considered me calmly with his bright little eyes, and forthwith solemnly spat out a still living ant in my direction. The inquiring look he then gave me, was exceedingly embarra.s.sing. Who was I not to be bound in chivalry by the accredited customs of his race?
With dignity and certainty of acceptance he had surrendered, calmly and without doubt he had proffered his little subst.i.tute of sword. It was, I felt, infinitely preferable to any guttural and cowardly "kamerad!"
Feeling rather shamefaced I accepted the weakly struggling ant, gently lowered the small saurian to the ground and opened my fingers. He went as he had surrendered, with steadiness and without terror. From the summit of a fallen log he turned and watched me walk slowly out of sight, and I at least felt the better for the encounter.
Of all tropical b.u.t.terflies, heliconias seem the most casual and irresponsible. The background of the wings of many is jet-black, and on this sable canvas are splashed the boldest of yellow streaks and the most conspicuous of scarlet spots. Unquestionably protected by nauseous body fluids, they flaunt their glaring colors in measured, impudent flight, weaving their way slowly through the jungle, in the face of lizard and bird. Warningly colored they a.s.suredly are. One cannot think of them except as flitting aimlessly on their way, usually threading the densest part of the undergrowth. No b.u.t.terflies are more conspicuous or easier to capture. They must feed, they must pay court and mate, and they must stop long enough in their aimless wanderings to deposit their eggs on particular plants by an instinct which we have never fathomed.
But these are consummations hidden from the casual observer.
Now, however, I am prepared for any unexpected meaningful trait, for I have surprised them in a habit, which presupposes memory, sociability and caution, manifested at least subconsciously.
The afternoon had worn on, and after leaving my lizard, I had squatted at the edge of a small glade. This glade was my private property, and the way by which one reached it from the nearby Convict Trail was a pressure trail, not a cut one. One pushed one"s way through the reeds, which flew back into place and revealed nothing. Lifting my eyes from the tragedies of a hastening column of army ants, I saw that an unusual number of heliconias were flitting about the glade, both species, the Reds and the Yellows. All were fluttering slowly about and as I watched, one by one they alighted on the very tips of bare twigs, upside down with closed wings. In this position they were almost invisible, even a side view showing only the subdued under-wing pigments which blended with the pastel colors of twilight in the glade, reflected from variegated leaves and from the opening blossoms of the scarlet pa.s.sion vine. Perhaps the most significant fact of this sleeping posture, was the very evident protection it afforded to b.u.t.terflies which in motion during their waking hours are undoubtedly warningly colored and advertised to the world as inedible. Hanging perpendicularly beneath the twig, although they were almost in the open with little or no foliage overhead, yet they presented no surface to the rain of the night, and all faced northeast--the certain direction of both rain and wind.
The first one or two roosting b.u.t.terflies I thought must be due to accidental a.s.sociation, but I soon saw my error. I counted twelve of the Red-spots and eight Yellows on two small bushes and a few minutes"
search revealed forty-three more. All were swung invariably from the tips of bare twigs, and there was very evident segregation of the two kinds, one on each side of the glade.
When I disturbed them, they flew up in a colorful flurry, flapped about for a minute or less and returned, each to its particular perch. After two or three gentle waves of the wings and a momentary shifting of feet they settled again to perfect rest. This persistent choice of position was invariably the case, as I observed in a number of b.u.t.terflies which had recognizable tears in their wings. No matter how often they were disturbed they never made a mistake in the number of their cabin. A certain section of a particular twig on a definite branch was the resting place of some one heliconia, and he always claimed it.
Several were bright and fresh, newly emerged, but the remainder were somewhat faded and chipped at the edges. The delicate little beings slept soundly. I waited until dusk began finally to settle down and crept gently toward a Red-spot. I brought my face close and aroused no sign of life. Then I reached up and slowly detached the b.u.t.terfly from its resting place. It moved its feet slightly, but soon became quiet.
Then I gently replaced it, and at the touch of the twig, its feet took new hold. When I released its wings it did not fly but sank back into the same position as before. I wondered if I was the first scientist to pluck a sleepy b.u.t.terfly from a jungle tree and replace it unawakened.
At the time I was more impressed by the romantic beauty of it all than by its psychological significance. I wondered if heliconias ever dreamed, I compared the peacefulness of this little company with the fierce ants which even now were just disappearing from view. These were my thoughts rather than later meditations on whether this might not be a sort of atavistic social instinct, faintly reminiscent of the gregariousness of their caterpillar youth.
