Chapter II: Part 2
The Needle all these years was still lying where the British Army left it, on the shore of the Bay of Alexandria. The ground on which it lay was sold, and a Greek merchant who had bought the land was anxious to have the column taken away. The Khedive advised the English to remove it if they really valued its possession, otherwise they ran the risk of losing it altogether. In 1867 Sir James E. Alexander was attracted by the beauty of the column which was also presented by Mehemet Ali to the French, and stands now in La Place de la Concorde. Remembering that the one belonging to the English was lying unheeded on the shores of Alexandria, he desired to have it brought over to England, and accordingly went to Egypt, gained an interview with the Khedive, and with him discussed its possession and removal. For ten years he was unwearying in his watch over the monument, arranging from time to time with the owner of the land to allow it to remain where it was, hoping meanwhile to be able to make some arrangements concerning it so that it might be preserved for the English.

He came to the opinion that if ever the obelisk was to be brought to England it would not be at the expense of the nation's purse, but would need to be paid for by private donations. With one or two friends, anxious like himself for the protection of the Needle, he intended to try and raise funds in the City. However, first meeting his friend, Professor Erasmus Wilson, and explaining all to him, the Professor generously offered to pay the sum of £10,000, which was deemed sufficient for the purpose.
In July of 1877 workmen were once more busy in connection with this column which already had experienced such a history. The sand was removed from about it, and to the delight of those most interested it was found to be in an excellent state of preservation. Next came the anxious task of removing it, something more being necessary than the raft, as of old, for the long sea voyage which lay before it.
THE FIRST ATTEMPT AT LAUNCHING. [_Photo._]
A paper might be written on the different methods and numerous plans invented and suggested for the transportation of the Needle. Sir James Alexander had made the acquaintance of Mr. John Dixon, a civil engineer, and he, too, was interested in the monolith. Professor Erasmus Wilson and Mr. Dixon were introduced and discussed the subject together, with the result that Mr. Dixon undertook the responsibility of the conveyance of the column to England, Professor Wilson arranging to pay the £10,000 on its erection in London. A construction was therefore carefully designed in England for encasing the Needle, so that it would be a sea craft of itself, and this was sent out to Egypt in pieces.
THE TUGS IN ACTION. [_Photo._]
One of the principal considerations when making their designs was that the Needle when encased required to be launched by being rolled into the water, instead of being sent off in the usual way. Another of the chief difficulties to contend with in the removal of the obelisk was that the bay near which it was lying was unsafe for ships to anchor in, as it was exposed to severe gales and the ground was covered with shoals. The Needle was raised some feet above the ground, the smaller end swung round to be parallel with the sea, and when in this position the work of encasing it was done.
When in this act of turning it, the ground appeared to be giving way under it, and, on examination being made, it was found to be resting on a small vault, which was 6ft. long by 3ft. wide and 4ft. high. It was evidently an ancient tomb, for two human skeletons and some small jars were found in the cavity. The skulls were preserved and put on board the pontoon, when ready for sea, but after the storm in the bay they were never seen again, and the sailors, being foreign, are supposed to have thrown them overboard, through superstition.
The Needle whilst raised and ready for encasing had the plates riveted in place round it, the inside was packed with elastic timber cushions to preserve the stone when being rolled into the water, or in case of any deflection in the vessel's length, which might occur through the waves. The casing was made water-tight, and the greatest care had to be taken to have the column quite in the centre of the cylinder, where it was fastened in position.

For the purpose of getting it into the water, large wooden wheels, 16-1/2ft. in diameter, were put on either end, and planks were laid for it to roll down. From heavy lighters lying in the bay, wire ropes were taken and wrapped many times round the cylinder. Also from the land side ropes were secured to it, in case, when set in motion, it went off at too great a speed, and thus the ropes could check that fault. On August 28th, 1877, all was ready for the launch. Unfortunately, the morning commenced with a thick fog, which only cleared away as the day wore on.
REPAIRING THE HOLE MADE BY THE ROCK. [_Photo._]
A great crowd of people gathered to witness the interesting event. All being in readiness, the winches on board the lighters worked the ropes connected with the encased Needle, and it commenced to gradually move towards the water, but the movement was so slow that it could scarcely be detected. After some hours it had only made one complete turn on its wheels. It was then proved that the vessels from which the wire ropes were worked were not able to hold their ground against the strain, but were dragging their anchors. Two tugs which had been standing by in readiness to give help if required were called into service, and being connected with the cylinder towed it until she moved a little farther into the water, but although the tugs steamed at full power they could not move the heavy weight at any great speed. The planking ended by an incline into the water, and divers had been previously employed in removing shoals from the intended course to prevent any mishap. When the cylinder was brought to the edge of the railway, so to call it, the idea was that it would roll down the incline and slip off easily into the water.

All the first day was employed in bringing it to the foot of the incline, and at night it was left in no greater depth of water than 3ft. Next morning the tugs again were at work trying to move it into deep water, but after making one full revolution it stuck, and although the tugs continued to tow all day it remained immovable.
FAREWELL TO ALEXANDRIA. [_Photo._]
On the third day divers discovered that a hidden stone weighing half a ton had pierced the plates, and making a hole had allowed the water to rush in and fill the cylinder. It took some days to repair the damage made by the rock, but after that was done it was successfully floated and towed round to the harbour, where final arrangements were made for the sea voyage. A cabin house and rail were fixed on top, two bilge keels 40ft. long were riveted one on either side, a mast and rudder placed, and twenty tons of iron ballast were put in her. It was manned by a crew of five Maltese and an English captain. The time occupied from beginning to encase it until the completion was about three and a half months.
A suitable steamer of sufficient size and power was found in the ss. _Olga_, belonging to Messrs. Wm. Johnson and Co., of Liverpool. The craft, which was named the _Cleopatra_, was now ready for sea. It was designed not to travel faster than five or six knots an hour, as greater speed might be disastrous. The _Olga_, towing the _Cleopatra_, set sail from Alexandria on the 21st September, 1877.
For the first twenty days all was prosperous and uneventful, but on the morning of Sunday, the 14th October, when in the Bay of Biscay, a squall arose, which towards noon developed into a gale. The _Cleopatra_, however, stood the gale well, not shipping enough water to do any serious harm until about six o'clock on the evening of the same day, when a big sea caught her, turning her completely on her beam ends and carrying away her mast.

A desperate effort was made to right her, but without success; a small boat was lowered, but to no purpose, and the captain of the _Olga_ at this point, seeing the danger all were in, thought it wisest to disconnect the two vessels, and so the cylinder was cut adrift. A little later, the wind having fallen, the _Cleopatra_ signalled for assistance, and the crew of the _Olga_, pitying the distress of their fellow-sailors, volunteered to put off in a boat and go to their rescue. The captain, thinking it would be a fruitless effort, advised them against it, saying: "A boat could not live in such a sea." The second officer, who had all along taken a keen interest in the welfare of the _Cleopatra_, replied: "We can't leave the poor fellows to drown; and now, lads, who will go with me?" He found five fine able-bodied men, in the prime of life, were willing to share the risk, and a boat was launched and put off; but before they could render any assistance a great wave washed them away, and they were thus drowned in endeavouring to save others.
After a time a line was thrown from the _Olga_ over the _Cleopatra_, and by means of it a boat was hauled from the one vessel to the other, and the sailors on the Needle were saved. After spending some hours in searching for signs of the lost boat and the _Cleopatra_, the captain of the _Olga_ set sail for Falmouth, with the sad news of the enforced abandonment in the Bay and the supposed loss of the Needle and men.
When the news was heard in England, Mr. Dixon was of opinion that the Needle would not sink when cast off, but would float, the only danger being that she might be destroyed on rocks. His surmising was correct in reference to it floating, for a telegram was received sixty days after the news of its loss saying that the ss. _Fitzmaurice_, bound for Valencia from Middlesbrough, had found and captured it ninety miles north of Ferrol, and had towed it into Vigo in Spain, and it remained in that harbour about three months.
Sir James Ashbury, M.P., kindly offered the loan of his yacht, the _Eothen_, to tow it home, but arrangements were finally made for the _Anglia_ to do the work, and she arrived in England with the obelisk in tow on the 20th January, 1878.
_Ivanka the Wolf-Slayer._
By Mark Eastwood.
The Prince threw the reins to his servant and sprang from the sledge.
"Where is he?" demanded he.
The Muzhik in the doorway of the hut stood bowing to the ground. He did not presume to lift his eyes to the High Noble, but they had flashed up like signal-fires at the words. Yet he affected not to understand.
"Is it the old man, Ivan Ivanovitch, the High Noble would honour with his commands?" he began. "His servant is full of regret----"
"Bother Ivan Ivanovitch!" interrupted the Prince, impatiently. "What do I want with your father? It is Ivanka, your son, I come to see--the little one who slew the wolf. At least," he added quickly, with a shrug, "so they say, but I do not believe it. Why, it is impossible! A child--a mere puppy!"
The Muzhik had thrown out his hands. He could contain himself no longer. "The High Noble does not believe?" he cried, wildly. Then he rushed into the house to return in a moment brandishing in one hand a knife, and in the other holding aloft a shaggy hide.
"The Noble Prince does not believe?" he repeated, and his eyes seemed to emit sparks. "Let him behold the proofs. Ivanka, my little one, slew the wolf, in very truth! Alone--alone he slew it!"
As though a flash of electric fire had flown from the man's lips direct to the hearts of his listeners, the faces of both flamed up. The man in the sledge lifted his cap and crossed himself with fervent mutterings. He passed the cuff of his coat across his wet, shining eyes.
The Prince took the knife in his hand. Such a thing it was! You can buy the like for twenty copeks (about sixpence) at any Russian fair. One of the sort used by the Russian peasant to cut forage, having a crooked blade and horn handle. It was stained, both blade and hilt, with blood.
"I have bought another for use," observed the peasant.
"It is wonderful," murmured the Prince, as he turned the knife about in his hands.
At this juncture a pair of excited black eyes, surmounted by a huge _baranka_, peered round the corner of the hut, and as quickly vanished.
Presently the Prince looked up. "But the boy!" he cried. "Let us see this wonderful child and hear the story from his own lips."
The peasant looked sharply round.
"He was here even when the High Noble drew up. There is the hatchet and the wood he was chopping. Ivanka! Ivanka! He has hidden himself, the rascal."
The Prince laughed.
"Ivanka Ivanka!" almost shrieked the peasant. "I will teach you to run and hide when the High Nobility come from far and near to see you! By all the saints, if you do not instantly come forth from your hiding-hole and relate the whole occurrence to the Noble Prince, I will break every bone in your body!"
Then it was that a coat of sheep's skin that just cleared the ground emerged from behind the hut and moved slowly over the trodden snow to within a few paces of the Prince. You could only tell by the shining eyes and the tip of a small red nose that peeped between the high stand-up collar that inside of it was a small boy.
Where he stood the blood-red sun bathed him in heroic glory. Yet, in spite of all, Ivanka the Wolf-Slayer had the mien of a fruit-stealing culprit before the _Chinovnik_. The Prince regarded him with mock severity.
"What is this I hear of you, Ivanka?" he began. "They say that you have slain a wolf!"
Ivanka would have hung his head but that his collar prevented it. So he dropped his eyes in guilty silence. The peasant, behind the Prince's back, rubbed his hands and chuckled.
"Come here," commanded the Prince, his moustached lip twitching with a whimsical smile.
The coat moved to the Prince's feet. Then the small boy inside it felt himself caught up in strong arms and borne into the hut.
Now, though it was a ruddy winter sunset outside, in the hut it was quite gloomy. The window was very small. A dull yellow glow, like a big bull's-eye, came from the open door of the stove, and a glimmer like a glow-worm from the tiny lamp that burned before the Holy Image. The dim outline of a woman with a child in her arms could be discerned by the stove. She came forward as the Prince entered, and bending low raised the hem of his fur mantle to her lips and silently returned to her seat.
The Prince sat by the window, and Ivanka stood between his knees where he had been placed. He trembled inside his sheep's skin. Yet it was a gentle hand that lifted the _baranka_ from his curly head and raised his chin.
"How old are you, Ivanka?" inquired the Prince.
"Ten years, Noble Prince," faltered the boy. But his eyes meeting those of the Prince at that moment he ceased to tremble. And the longer he looked the more comfortable he felt.
"And you have slain a wolf?" continued the Prince.
"Yes, Noble Prince."
"And what had the wolf done to you, Ivanka, that you should have taken his life?"
"He had seized our little Minka and would have eaten her up." Ivanka drew a sharp breath.
"How terrible!" exclaimed the Prince. "But you--midge! How did you dare to tackle such a foe? It is incredible! Come, tell me all about it. Begin at the beginning, Ivanka."
Ivanka gazed at the ground in silence. He twisted one leg round the other, cracked all his knuckles in succession, but the words would not come.
"Speak, Ivanka, do," came a woman's coaxing voice from the gloom. "Tell his High Nobility how it happened."
Another pause, and at length in a shy, hesitating voice, Ivanka began:--
"Mother had gone to the town in the sledge, and father lay asleep on the top of the stove. It was afternoon. I was minding Minka, and we played at having a shop with the bits of pot from the mug Minka broke. Then I remembered it was time to cut the fodder and feed the beasts, which I can do as well as father now. So I took the fodder knife and stole out. I left the door open a bit--not enough to let the cold in on father, but enough to hear Minka if she cried. I had fed the cows in the byre and had got to the corner of the house coming back, when I heard Minka scream."
As Ivanka uttered the last word his breath came fast. He tossed back his locks with a sudden jerk of the head. Like a gladiator preparing for combat, he threw out his chest, setting his teeth, whilst his small, muscular fingers contracted, doubling in like the claws of a falcon. Forgotten was the princely presence with that piteous appeal smiting his ears.
"I sprang forward," he continued, "and saw Minka. She was on the ground just outside the door. And over her hung a monster, grim and terrible. His wicked eyes gleamed red, and his cruel teeth were long and sharp. I saw them as he lifted his bristling lip to seize her in his jowl."
A dry sob rose in Ivanka's throat and made him pause. He coughed it impatiently away.
"It seemed to me then--just for a moment of horror--as though my limbs were bound and I could not move, until the beast began to drag Minka away. At the sight strength came to me, and with a yell I threw myself upon him."
"You were not afraid?" put in the Prince, who had never taken his eyes off the boy since he began to speak.
"I did not think of fear," replied Ivanka, "I thought of my poor little Minka, and oh, how fiercely I hated the monster. Hate kills fear," he added, reflectively.
"And then?" inquired the Prince.
"Oh, then he dropped Minka, and over and over we rolled in the snow, he snarling and worrying my sheep's skin. He would soon have made an end of me but for my sheep's skin." And the boy patted his breast and looked himself over complacently.
"And after?" the Prince again recalled him.
"After that he shook me until my bones rattled in my skin. Then I was under him and my mouth was full of his hair, and I was so spent that I would have let him finish me. But Minka cried, 'Ivanka! Ivanka!' and it seemed too hard to leave her. It was that moment I remembered that I still grasped the knife.
"How I struggled round between his mighty paws until my arm was free to plunge the weapon in his throat I know not, but I felt the blood gush out over my face. And then--and then, Minka's voice went farther and farther away and I seemed to be falling as a star falls through the air."
As Ivanka ceased speaking, a half-stifled sob was heard from the interior of the room. The Prince had covered his eyes with his hand as though dazzled. Yet the sun had gone down and the place was more gloomy than ever. The peasant stepped forward out of the shadows and stood before the Prince in the dim light of the window. He took up the tale.
"It was the screams of the little one that awoke me, your High Nobility, and I ran out. Ah, never shall I forget the sight that met my eyes! There lay my little son, dabbled in blood, and beside him the wolf on its back, kicking in death convulsions. When I picked up my Ivanka I thought him dead, and my heart would have broken had he not at once opened his eyes.
"'Minka,' he whispered, 'is she hurt?'
"'My darling, no,' I answered. 'She screams too lustily to be hurt.'
"'And the wolf?' He raised his head from my shoulder and looked wildly around.
"'He is dead. You have slain him, my hero,' I assured him.
"Then he shut his eyes with a great sigh.
"'Let me sleep, father,' he murmured. 'I am so tired.'"
The peasant chuckled. "He was played out, my little wolf-slayer. The Noble Prince should have seen how he lay like a sack, and slept and slept!"
Meanwhile Ivanka had grown shy again and gazed wistfully towards the door. But the Prince still held him between his knees. Even when he rose to go, the High Noble detained the boy with a hand on his head.
"Give him to me," he said to the peasant. "Let me take him with me when I go to Petersburg. I will make a great man of him. He shall be a soldier and fight for the Czar."
There was dead silence. The peasant's face had gone crimson. His eyes flew to his son and held him in jealous regard.
"Will you go with me, Ivanka, you wolf-slayer, to help keep the human wolves from invading the dominions of the Czar? You shall be taught with the sons of the highest in the land, and shall wear the uniform of an Imperial cadet."
Ivanka raised solemn eyes to the face that was bent towards him. It was a noble face, handsome and benign, and imposing against the swelling sable of the high collar.
"He is great and good and beautiful, like my patron saint, Ivan," he thought. Something stirred in the gloom of the hut, and quickly Ivanka turned to where his mother sat with the sleeping Minka in her lap. His lip began to quiver.
The peasant found his tongue. "Give him time, Noble Prince," he faltered, huskily, and he too looked towards the crouching figure by the stove. "It is a great thing the High Noble offers, but the boy is very young."
"Take your time," replied the Prince. "In the spring I shall return. Then, since you are sensible people, he will be ready to go."
With these words the great man stooped and kissed Ivanka, pressing a roll of notes into his hand. From the door Ivanka watched the Prince depart. He gazed after the fine sledge with its prancing horses as they sped, swift as the wind, towards the wonderful, mysterious city of the Great Czar. When it had disappeared and the merry jingle of the silver bells no longer reached his ear it was to him as though a bright noontide sun had suddenly dropped from the heavens. And there and then a feeling of longing after greater things crept into his valiant little heart.
"You shall decide for yourself, my son," said the peasant. And the mother hid her grief because she wished Ivanka to be a great man.
Thus it was that when the spring came to stir the sap in the trees and release the ice-bound brooks, at the return of the Prince, Ivanka was ready to go.
_In Nature's Workshop._
II.--FALSE PRETENCES.
By Grant Allen.
Human life and especially human warfare are rich in deceptions, wiles, and stratagems. We dig pitfalls for wild beasts, carefully concealed by grass and branches; we take in the unsuspecting fish with artificial flies, or catch them with worms which conceal a hook treacherously barbed for their surer destruction. The savage paints his face and sticks feathers in his hair so that he may look more terrifying to his expected enemy; civilized men mask their batteries, and sometimes even paint muzzles of imaginary guns in the spaces between the gaping mouths of the real ones. _Chevaux de frise_ block the way to points liable to attack; real troops lie in ambush and dart out unexpectedly in the rear of the assailants. Trade in like manner is full of shams--a fact which I need hardly impress by means of special examples. But Nature we are usually accustomed to consider as innocent and truthful. Alas, too trustfully: for Nature too is a gay deceiver. There is hardly a device invented by man which she has not anticipated: hardly a trick or ruse in his stock of wiles which she did not find out for herself long before he showed her.
I propose in this paper to examine a few cases of such natural deceptions--not indeed the most striking or typical, but such as occur among fairly well-known English plants and animals. And I shall begin with our familiar and unsavoury old friend, the Devil's Coach-horse.
In order fully to understand his mode of procedure, however, I must first call your attention to another animal which really _is_ what the Devil's Coach-horse mendaciously pretends to be: and that is the common scorpion. His mode of fighting is well known to most of us. In illustration No. 1 Mr. Enock has given us a delineation of a frantic death-struggle between such a scorpion and a large and powerful southern spider. The venomous creature with the stinging tail is on the left; the spider is on the right. As far as mere size goes, the antagonists are fairly well matched: but the scorpion is the best armed, both with offensive and defensive armour. His lobster-like or crab-like claws enable him to hold his enemy's limbs in his grip as in a vice: then, at the critical moment, he bends over his tail, in the extremity of which his sting is situated, and plunges it with force through the comparatively slight skin of the spider's body or thorax, injecting at the same moment a pungent drop of his deadly poison. This characteristic action of the scorpion in curving its tail over its body and raising its sting in a menacing attitude is well known to birds and other enemies of the species: often the mere threat of a thrust is a sufficient deterrent: the dangerous beast just elevates its poisonous appendage or assumes an angry mien, and the inquisitive intruder is frightened away immediately. It is the same with ourselves. The bare sight of that uplifted sting suffices to repel us. Even a child who saw a scorpion once arch its back and prepare to strike with its reversed tail would instinctively understand that there was danger ahead, and would withdraw its hand before the venomous creature had time to pounce upon it.
Owing to these unamiable personal traits of the scorpion race, it is not popular among other animals. But to be feared is to be respected; and scorpions for the most part are left severely alone, under the stones where they love to lurk, by the various denizens of the districts they inhabit. Now, it is a fact in nature as in human life that to be successful is to have many imitators. Thus a number of harmless flies dress up like wasps in black and yellow bands, and so escape the too pressing attentions of insect-eating birds and other enemies. They have no stings, to be sure, but they look so like the wasps, and flaunt about so fearlessly in their borrowed uniform, that they are universally taken for the insects they mimic; even the cautious entomologist himself stares at them twice and makes quite sure of his specimen before he ventures to lay hands on any such doubtful masquerader. I hope in a future article to give some further account (with illustrations) of these facts of _mimicry_, as it is called: for the present we will stick close to our text, the Devil's Coach-horse. For this familiar English beetle is an imitator of the scorpion, and obtains immunity from the attack of enemies to a great extent by pretending to powers which are not his in reality.
In No. 2 we have a portrait of the Coach-horse in his hours of ease, seen from above, engaged in doing nothing in particular. He does not _look_ like a flying insect, but he is. He has a long pair of wings tucked away in folds under his horny wing-cases, and he can use them with great effect, for he is one of our swiftest and strongest fliers--the long-distance champion, I almost fancy, among the beetles of England, unless indeed the tiger-beetle be pitted against him. But when crawling on the ground, and attacked or menaced, he does not take to flight or show the white feather: being a pugnacious and spirited little beast, he bridles up at once, and endeavours incontinently to terrify his assailant. In No. 2 you see him from above when he is merely engaged in crawling along the ground, looking as mild as milk, and as gentle as any sucking dove: you would hardly suppose he could show fight or raise his hand--I mean his antennæ--to injure anyone. But in No. 3 he is represented in his favourite act of attacking a caterpillar: for he is really a very voracious and courageous carnivore. In the autumn, when Devil's Coach-horses are usually most abundant, you can easily catch them by putting a piece of meat or a dead frog under an empty flower-pot, and then tilting the edge up with a stone, so that the beetles can crawl in and get at the food thus temptingly laid out for them.
If you disturb the Coach-horse, however, while he is engaged in eating his quiet meal, or even when he is walking at leisure along a country road, he puts himself at once into his "terrifying" attitude, and imitates the scorpion. No. 4 exhibits him in this military character, cocking up his tail and pretending he can sting--which is only his brag: he just does it to frighten you. But the attitude is so exactly like that of the scorpion, that it almost always produces an immediate effect: hardly anybody likes to molest a Devil's Coach-horse. If you put down your hand to touch him, and he rears in response, ten to one you will withdraw it in alarm at sight of him. In England these beetles often enough find their way into larders or cellars, seeking whom or what they may devour; and when the servants light upon them, they almost invariably decline to touch them: there is a general opinion about that the ugly and threatening black beasts are uncanny and poisonous, or else why should they turn up their tails at you in such an insulting fashion?
"But," you may object, "there are no scorpions in England: how then can the Devil's Coach-horse be benefited by imitating an animal which he has never seen, and of whose very existence he has not been able to read in pretty picture books?" Your objection has some force--though not so much as you imagine. It is quite true that there are no scorpions in England; but then, there are Devil's Coach-horses in many other countries, and the habit of tail-cocking need not necessarily have been acquired in these islands of Britain. That is not all, however: it suffices the beetle if the tactics it adopts happen to frighten and repel its enemies, no matter why. Now, in the first place, many of our migratory birds go in winter to Southern Europe and Africa--especially the insect-eaters, which can find no food in frozen weather. The hard-billed seed-eaters and fruit-eaters remain with us, but the soft-billed kinds retire to warmer climates, where food is plentiful. Of course, however, it is just these insect-eating birds that the Devil's Coach-horse has most to fear from. The birds must be quite familiar with the habits and manners of scorpions in their southern homes; and they are not likely to inquire closely whether the dangerous beast they know on the Mediterranean has, or has not been scheduled in Britain. We all of us dislike and distrust any insect that resembles a bee or wasp, and that buzzes or hums in a hostile manner: we give all such creatures a wide berth, wherever found, on the bare off-chance that they may turn out to be venomous--be hornets or so forth. Just in the same way, a bird, when it sees an unknown black beastie cock up its tail and assume a threatening attitude, is not likely to inquire too curiously whether or not it is really a scorpion: the bare suspicion of a sting is quite enough to warn it off from interfering with any doubtful customer. Moreover, in the second place, even those birds or men who have never seen a scorpion at all are yet sure to be alarmed when an insect sticks up its forked tail menacingly, and shows fight, instead of skulking or flying away. As a general rule, if any animal makes signs of resistance, we take it for granted he has adequate arms or weapons to resist with: and so this mere dumb-show of being a sort of scorpion proves quite sufficient to protect the Devil's Coach-horse from the majority of his enemies.
I ought to add that while our beetle thus frightens larger enemies, he is actively and offensively objectionable to small ones. The main use of his tail, indeed, is for folding away his wings, much as the earwig folds hers by aid of her pincers. But the Devil's Coach-horse makes it serve a double purpose. For he has a couple of yellow scent-glands in his tail, which secrete an unpleasant and acrid aromatic substance. These scent-glands are protruded in No. 4: you can just see them at the tip of the tail; and if the annoyance to which the beetle is subjected seems to call for their intervention, a drop of the volatile body they distil is set free, and is at once discharged in the face of the enemy. Such a manoeuvre is in essence like that of the skunk: it is defence by means of a nasty odour, and it occurs not only in the Coach-horse's case, but also among a number of beetles and other insects.
The odd little creatures known as Bombardier Beetles are still quainter in their habits: they carry the last-mentioned mode of defence to an even greater pitch of perfection. For, like miniature artillery-men, they actually fire off a regular volley of explosive gas in the faces of their pursuers. The gas is secreted as a liquid; but it is very volatile, and it vaporizes at once on contact with the air, so as to form a small, white cloud of pungent smoke, resembling in its effects nitric acid. Our native English species of Bombardier roams about in large flocks or regiments: and when one member of a clan is disturbed, all the other beetles of the company let off their artillery at once, so that the scattered volley has something the appearance of platoon firing. The chief enemy of the Bombardiers is a much larger and very handsome carnivorous beetle known as Calosoma. When this insect tiger hunts down a single Bombardier, and has almost caught him, the fugitive waits till his pursuer is quite close, and then salutes him with a discharge of fire-arms: the pungent gas gets into the Calosoma's eyes and mouth and distracts him for a moment; and the Bombardier escapes in the midst of the confusion thus caused, under cover of the cloud he himself has exploded. That is the most highly evolved mode of defence of which I know among the British insects.
There are few creatures, again, which one would so little suspect of any attempt to bully and bluff others as the soft-bodied caterpillars. They are as a rule so plump and squashy and defenceless: a mere peck from a bird's beak is enough to kill them, for when once their tight, thin skin is broken, were it but with a pin-prick, all the flabby contents burst out at once in the messiest fashion. Yet even caterpillars, strange to say, have their tricks of terrifying. They pretend to be dangerous characters. I will set out with some of the simplest and least developed cases, and then pass on to a more complex and wily class of deceivers.
To begin with, I must premise that two sets of caterpillars have two different ways of evading the unpleasant notice of birds and other insect-eaters. One way is that adopted by the common "woolly-bear," a great hairy caterpillar, frequent in gardens, and covered from head to tail with long needles or bristles. These prickly points make the creature into a sort of insect hedgehog; birds refuse to touch him, because the serried spikes, which to us are mere hairs, seem to them perfect spines or thorns, sticking into their tongues and throats, or clogging their gizzards. Protected caterpillars like the woolly-bears live quite openly, exposed on the leaves and branches of their food-plant; they are not afraid of being seen: nay, they rather court observation than shun it, because they know nobody will attack them. The porcupine has no need to run away like the rabbit. Similar tactics are also adopted by many nasty-tasting caterpillars, in whose bodies natural selection has developed bitter or unpleasant juices. These caterpillars are rejected by birds and lizards--the great enemies of the race--and therefore they find it worth while to clothe themselves in gaudy and conspicuous red or yellow bands, so as to advertise all comers of their inedible qualities. Whenever you see such brilliantly-attired grubs (like those of the Magpie Moth, so common on gooseberry-bushes--a striking creature tricked out in belts of black and orange), you may be sure of two things: first, they live openly and undisguisedly on the leaves of their food-plant, without any attempt at mean concealment; and second, they are nasty to the taste, and therefore rejected as food by insect-eating animals. Now and then a young and inexperienced bird may eat one, to be sure; but it never tries twice, and the solitary martyr is sacrificed for the good of the race. Their bright colours and gaudy bands are just advertisements, as it were, of their inedible qualities. For, of course, nasty taste would do a caterpillar no good if the bird had always to sample it before rejecting it; the broken skin alone would be enough to kill it. Hence almost all uneatable caterpillars have acquired bright colours by natural selection--that is to say, by the less bright being continuously devoured or killed; and birds on their side have learned to know (after one trial, or, perhaps, even before it by inherited instinct) that red or yellow bands and belts in caterpillars are the outward and visible sign of uneatableness.
The second group or set of caterpillars is edible and tasty: it, therefore, governs itself accordingly, and has recourse to the exactly opposite tactics. Caterpillars of this class are smooth and naked: they never have the brilliant "warning colours" of the nasty-tasted kinds: and they show a marked absence of the beautiful metallic sheen, the strange melting iridescent hues and spots which add beauty to the charms of so many among the uneatable species. Such fat and smooth-skinned edible caterpillars are, of course, very tempting juicy morsels to birds and other insect-eating animals. Their motions, like those of all grubs, are slow; and if they lived exposed on their food-plants, after the fashion of the protected hairy and bitter kinds, they would all he eaten up before they had time to turn into moths or butterflies. Here, therefore, natural selection has produced the contrary result from that which it produces among protected kinds. Caterpillars of this edible type which showed themselves too openly and imprudently have got picked off by birds, like sentries and pickets who make themselves too conspicuous to the enemy's sharpshooters. Only the most prudent, modest, and retiring grubs have survived to become moths or butterflies, and so be the parents of future generations, to whom they hand on their own peculiarities. In this way the edible caterpillars have acquired at last a fixed hereditary instinct of lurking under leaves, or in dark spots, and never showing themselves openly. The larvæ of the butterfly group as a whole thus fall into two great classes (as far as regards habits alone, I mean): the _protected_, which are either hairy or nasty, and which flaunt themselves openly; and the _unprotected_, which lurk and skulk, endeavouring to escape notice as sedulously as their rivals the protected endeavour to attract it.
Nor is that all. It would clearly be useless for a bright red or yellow caterpillar to hide under a green leaf, and then suppose by that simple device he was going to escape observation. Birds are always looking out for insects under leaves. The consequence is that skulking or lurking caterpillars are soon found out by sharp-eyed and hungry enemies, unless they closely resemble the foliage or stems upon which they lie. From generation to generation, accordingly, the less imitative insects get eaten, and the more imitative spared: so that nowadays, most unarmed caterpillars are green like the leaves or grey like the stems, and are even provided with markings of light and shade upon their skins which mimic the distribution of light and shade among the ribs and veins of the surrounding foliage. Such deceptive leaf-like caterpillars are always very difficult to find: so that careless observers as a rule know only those of the other type, the great hairy "woolly-bears" and the brilliant red and yellow-banded bitter kinds; they never observe the unobtrusive green and brown sorts, which harmonize so admirably with their native tree in colour and markings.
Many greenish caterpillars, however, when discovered and disturbed, fall back on their second line of defence: they endeavour to frighten their enemies by devices closely similar to those of the Devil's Coach-horse. The caterpillar of the Broad-bordered Bee-hawk, for example, forms a good instance of a very simple stage in the development of such brazen-faced "terrifying" tactics. This warlike grub is shown in No. 5, trying on its simple little attempt to make itself alarming. Though by no means an uncanny-looking or appalling insect, it will rear itself up on its haunches (so to speak) when attacked, raising the fore part of its body erect with a sudden jerk, and holding its head high, as if it meant to bite or sting, so as to give itself as formidable an aspect as possible. The mild ruse succeeds, too; for birds will eye the harmless creature askance when it attempts this evolution, putting their heads on one side, and ruffling their crests in evident terror. The attitude is all a simple piece of bluff, to be sure, but _it pays_; indeed, bluff in warfare is often more than half the battle. If you put on a bold face in a row, and seem able to take care of yourself, people are apt to think you have a knife up your sleeve, and therefore to refrain from unnecessarily annoying you.
The cunning caterpillar which finally develops into the Privet Hawk-moth has a slightly more evolved mode of purely theatrical frightening. You see him in No. 6, a full-fed specimen, just ready to turn at once into a chrysalis. This grub feeds usually on the vivid leaves of the privet; he is therefore protectively coloured a bright green, like that of the foliage about him. "But why those great purple stripes on his sides?" you will ask. "Surely they must make him an easy mark for birds?" Not at all: please notice that they run obliquely. There is method in that obliquity. When the caterpillar is smaller, he lurks unseen on the under-side of the leaves, and this pattern of oblique purplish lines exactly imitates the general effect of the shadows cast by the ribs--so much so, that if you look for him on a privet-tree in spring, I doubt whether you will find him till I point him out to you. Even when he waxes fat and full fed, the purple stripes still aid him more or less by breaking up the large green surface into smaller areas, as Professor Poulton has well noticed. He harmonizes better so with the broken masses of the leaves about him. Then again, when the time arrives for him to turn into a chrysalis, he descends to the ground, which, under a thickly-leaved privet bush, is most often brown. So, just as he is coming of age and reaching the proper moment for migration, his back all at once begins to turn brown, in order that he may be less observed as he walks about on the stem; while by the time he is quite ready to take to the earth he has grown brown all over, thus matching the soil in which he has next to bury himself. You could hardly have a better example of the sort of colour-change which often accompanies altered habits of living.
In the illustration, however, you see this really harmless and undefended grub in the act of trying to pretend he is poisonous. He is now mature, and the stripes on his sides stand out conspicuously as he walks on the stem. A sparrow threatens him. He retorts by showing fight--fallaciously and deceptively, for he has nothing to fight with. He lifts his head with an aggressive air, and throws himself about from side to side, as if he knew he could bite, and meant to do it. He also lashes his tail in pretended anger--"I would have you to know, Sir Bird, I am not to be trifled with!" The empty demonstration usually succeeds: the sparrow gets alarmed and believes he means it. This policy is, in essence, that commonly known as "spirited": it consists in trying to frighten your enemy instead of fighting him.
The oddly-marked caterpillar of the Puss Moth carries the same plan of campaign to a much more artistic pitch. This very quaint insect is common on willows and poplars in England, and is on the whole protectively coloured. Black at first, it looks like a mere speck or spot on the leaf; as it grows, it becomes gradually greener, relieved with broad purple patches on the back, which produce the effect of lines and shadows. When quite full-grown, as seen in No. 7, the adult caterpillar generally rests at ease on the twigs of the willow-tree. Our illustration shows it in this final stage of its larval life, just taking alarm and humping its back at the approach of some bird or other enemy. If the alarm continues, it goes through a most curious series of evolutions, admirably shown by Mr. Enock in No. 8. Here, the little beast is altogether on the defensive: it withdraws its head into the first ring of the body, and inflates the margin, which is bright red in colour. Two black spots, which are not really eyes, but which look absurdly eye-like, now give it a grotesque and terrifying appearance. In fact, the inflated ring resembles a hideous grinning mask, and gives the impression of a face with eyes, nose, and mouth, like that of some uncanny creeping creature. But the apparent face is not a face at all: it is artfully made up of lines and spots on the skin of the body. At the same time that the caterpillar thus assumes its mask, it stands on its eight hind legs as erect as it can, and whips out two pink bristles or tentacles from the forked prongs at the end of its tail--you can see them in the picture. It then bends forward the tail, and brandishes or waves about these pink bristles over its false head, so as to present altogether a most gruesome aspect. Indeed, even Mr. Enock's vigorous sketch of the little brute in its tragic moments does not quite convey the full effect of its acting in the absence of colour: for the bright red margin and the swishing pink switches add not a little to the telling smirk and black goggle-eyes of the mask-like face thus produced _in terrorem_.
That is not all, either. The Puss Moth caterpillar has a rapid trick of facing about abruptly in the direction of the enemy as if it meant to bite: and this trick is always most disconcerting. If ever so lightly touched, it instantly assumes the terrifying attitude, and presents its pretended face to the astonished aggressor. From a harmless caterpillar it becomes all at once a raging bulldog. Touch it on the other side, and it faces round like lightning in the opposite direction. Professor Poulton tried the effect of its grimace on a marmoset, and found the marmoset was afraid to touch the mysterious creature. We are not marmosets, but I notice that most human beings recoil instinctively from a Puss Moth caterpillar when it assumes its mask. Even if you _know_ it is harmless, there is something very alarming in its rapid twists and turns, and in the persistent way in which it grins and spits at you.
Really spits, too; for the insect has a gland in its head which ejects, at need, an irritating fluid. If this fluid gets into your eyes, they smart most unpleasantly. It contains formic acid, and is strong enough to be exceedingly stinging and painful. The discharge repels lizards, and probably also birds, who are among the chief enemies of this as of other caterpillars.
The deadliest foe of the Puss Moth larva, however, is the ichneumon-fly, a parasitic creature, which lays its eggs in living caterpillars, and lets its grubs hatch out inside them, so as to devour the host from within in the most ruthless fashion. There are many kinds of ichneumon-fly, some of them very minute: the one which attacks the Puss Moth in its larval stage is a comparatively big one. The fly lays its eggs behind the caterpillar's head, where the victim is powerless to dislodge them. In all probability the defensive attitude and the shower of formic acid are chiefly of use against these parasitic foes: for when an ichneumon-fly appears, the caterpillar assumes his "terrifying" attitude the moment it touches him, and faces full round to the foe with his false mask inflated. A very small quantity of the formic acid Professor Poulton found sufficient to kill an ichneumon: and there can be little doubt that this is its main object.
The last of these "bluffing" caterpillars with which I shall deal here is that of the Lobster Moth. In No. 9 you see a couple of these quaint and unwieldy creatures "demonstrating" before an enemy, as if he were the Sultan. The Lobster Moth in its larval stage frequents beech-trees, and you will see in the illustration that the two represented are on a twig of beech. When at rest, the caterpillar resembles a curled and withered beech-leaf, and by this unconscious mimicry escapes detection. But when discovered and roused to battle, oh, then he imitates the action of the spider. He holds up his short front legs in a menacing attitude, so as to suggest a pair of frightful gaping jaws: the four long legs behind these he keeps wide apart and makes them quiver with rage in the most alarming pantomimic indignation. His tail he turns topsy-turvy over his head like a scorpion; while the forked appendages at its end seem like frightful stings, with which he is just about to inflict condign punishment on whoever has dared to disturb his quiet. But it is all mere brag, though the whole effect is extremely terrifying. The performance does not, indeed, mimic any particular venomous beast, but it suggests most appalling and paralyzing possibilities. Many of these queer attitudes, indeed, owe their impressiveness just to their grotesque simulation of one knows not quite what: they are not definite and special, they are worse than that; they appeal to the imagination. And if only you reflect how afraid we often feel of the most harmless insects, merely because they _look_ frightful, you will readily understand that such vague appeals to the imagination may be far more effectual than any real sting could ever be. We dread the unknown even more than the painful.
