THE AWAKENING OF THE DORMOUSE

He lay face downwards—two tiny fists tight-clenched against his cheeks, his feet curled up to meet them, his tail swung gracefully across his eyes.

Nine weeks had he lain thus, self-entombed. Within the hollow of the old hazel-stump he had fashioned a rough sphere of honeysuckle bark; within this, again, a nest of feathery grass stems. He had put the roof on last of all.

A winter sunbeam pierced the screen of woodbine, and, for a moment, shed the warmth of springtime on the nest. His whiskers gave a feeble flicker in response. Next day the treacherous radiance lingered. He unclenched one fist, and wound four tiny fingers round a grass-stem. On the fourth day he half-opened his eyes (even half-opened they were beautiful), and sat up, dazed and blinking. The sunbeam had reached his heart.

“WHAT, AWAKE?” SHOUTED THE SQUIRREL.

Yet it was a full hour before he was conscious that he lived. At first he felt nothing but a dull quickening throb within his body. His feet and hands were ice-cold, and he swayed from side to side, feeling for his strength. Then came the pricking of ten thousand tiny needles in his limbs. His heart beat as though it would burst its prison. His whole frame quivered. His bristles stood stiff-pointed from their roots. As the heart-throb slowed, his muscles slackened and obeyed his will, but yet he felt that something was amiss. Before him danced a yellow quivering haze, his feet were heavy and awkward, his chest ached as he breathed, and he was cold, oh, so cold! It was no easy matter to reach the nest-top. He climbed mechanically upwards, digging his toes into the meshwork of the sides, and sobbing from sheer weakness as he climbed.

He made a small parting in the roof, and peeped out. It was only for a moment, for he fell back stunned and blinded by the glare. Still, in that moment, he had caught a glimpse of an unfamiliar world, leafless, lifeless, silent, miserable. He tucked his nose between his four paws, swung his tail across his eyes, and waited patiently for the darkness. With the darkness came the cold. It stole upon him gently, quelled the heart-throb, reclenched the tiny fists, and lulled him to forget.

It was better the next time. The old hazel was making coquettish efforts to renew its youth. It had hung its last remaining shoot with dancing catkins. Here and there lurked a crimson bud, ready to catch the floating pollen. On the sloping banks below were splotches of violet and primrose, and, over all, hung the green shimmer of spring.

To the dormouse’s eyes the glare was, for the first few moments, as painful as before, but this time it was tempered with moisture. Great rain-drops swung on the swaying grass-stems and twinkled with a thousand prismatic colours. The slow drip of the woods resounded in his ears.

As his hearing sharpened, the old familiar sounds returned, the chirping of the titmice, the starling’s discord, the sniggering of the robin, the squirrel’s bullying cough. How he had hated the squirrel—a midget incarnation of mischief, whose whole life was spent in practical joking. How often had he heard that hateful cough shot into his ear, as My Lady Shadowtail whisked past him, a sinuous brown flash curling round the tree trunk! How often had he promptly dropped his hard-earned nut in consequence, only to see it seized by a field-mouse! How often had he swung at the end of a tapering twig, while the squirrel feinted at him with all four paws!

He looked up, and caught the squirrel’s eye.

“What, awake?” she shouted. “It’s not quite time for good little dormice. You wait till it’s dark, and see how cool it is. Why, even with my tail (and she bent it into a figure of eight to show its amplitude) it is hard enough to keep warm.”

(L) MY LADY SHADOWTAIL. (R) MOTHER!

“Chuc!”

The dormouse had felt it coming, and had discreetly retired. As it was, the better part of the roof caved in, the result of slight mistiming on the part of the squirrel.

“I wish you wouldn’t do that,” said the dormouse.

He was addressing vacancy, for the squirrel had in the mean time completed the circuit of three tree-tops. She was back again, however, in time to catch the next remark.

“Have you any nuts?” said the dormouse. “I feel most horribly hungry, and this light is very trying to my eyes. It will have to be darker before I can hunt for any myself.”

“You’ll be asleep two hours before it’s dark,” said the squirrel, “and I haven’t any nuts, or rather, I haven’t the least idea where I put them. Didn’t you make a store?”

“Only a small one—seeds, I think,” said the dormouse. “I was very drowsy when I made it, and I daren’t hope that it is in good order.”

“Where is it?” said the squirrel.

“The second hazel on the left,” said the dormouse; “the third hollow from the top.”

The second hazel on the left was twenty yards away. Before the dormouse had finished speaking the squirrel had started, and the boughs by which she reached it were still quivering as she returned.

“There’s your store.”

The dormouse looked up, and gave a dolorous squeal of disappointment. A straggling nosegay was being thrust through the roof, and he realized at once that the seeds had sprouted.

“Why didn’t you nibble the ends off?” said the squirrel. “You can’t expect seeds to be seeds for ever. Oh, it’s your first hibernation, is it? Well, you’ll know better next time. Here’s a nut for you.” She had held it concealed in her palm, and produced it like a conjuror.

“She’s not such a bad sort, after all,” thought the dormouse, as he proceeded to examine the nut.

It was a hard nut, and would take some getting through. He sat back on his haunches, grasped it in his eight little fingers, gave it a twirl or two, and commenced gnawing three strokes a second. He gnawed for two minutes without a break.

It was harder than any other nut he remembered. He had never been more than a minute getting through one; sometimes they had obligingly split in half before he had fairly started. He tried another part, and worked even more vigorously than before.

Assuredly it was the very hardest nut in all the world. Twenty minutes’ hard work produced a small round hole, ten minutes more enlarged it so that he could thrust his lips inside. Then he sucked vigorously to secure the kernel, and secured instead a mouthful of black dust.

Of course the squirrel had known it all along. It did not need the guffaw he heard above to tell him that. This time he did not even protest. His spirit was broken. He was cold and tired and hungry. He merely huddled in a corner, still grasping the nut, and breathing in queer short gasps.

“Never mind, dormouse,” shouted the squirrel, “you will know a bad egg next time. Try this.”

For five seconds there was a faint rasping sound, then a sharp crack, and the rustle of two half-nutshells through the leaves. One of them struck the side of the hazel-stump and bounded off like an elastic ball. Before the dormouse had collected his wits, a fine kernel was thrust through the nest and the squirrel had once more regained her bough.

“Eat it,” she shrieked; “eat it before the sun goes down. It’s going now.”

And it was. Before a quarter of the kernel was accounted for, the western sky had turned to lurid orange; before the half was gone, the chill struck him. The nut dropped from his nerveless hands, his limbs tightened, his ears sank into his skin, his eyelids drooped, and he was asleep once more.

The primroses had long yielded pride of place to the daffodils; these in turn had paled before the marsh marigolds, but the most glorious yellow in the picture was the Sulphur Butterfly. He zigzagged lightly down the hedgerow, catching the sunshine at every turn, and the marigolds drooped their heads at the sight of him. Close to the nest he dropped on a briar-leaf, like a floating petal. He was more than colour now—he was form. For a full minute he poised there motionless, the most exquisitely graceful, the most exquisitely coloured of all our butterflies, and, for a full minute, the dormouse watched him.

Next came a quivering, amber-tinted flight, resolved at rest into a delicate medley of green and white and saffron. It was the orange-tip, and the dormouse rejoiced, for the orange-tip meant spring. Such dainty frailty could never stand the winter.

To tell of all he heard and saw that day would fill a book. At first, as he peered through the crevices, he only grasped the more vivid tints—the azure of the hyacinth, the roseblush of the almond, the crimson glow of the clover, the purple of the foxglove. Then, as his senses quickened, the whole glorious colour-scale, from ashbud to whitethorn, stood revealed.

From heaven above came the skylark’s defiant challenge; from earth beneath the fussy scream of the blackbird; on all sides the tweetings, twitterings, chirrupings, chirrings and pipings of petulant finches, and, in tender modulation to the avian chorus, the deep-throated, innumerable, drowsy hum of insects. Colour and sound, love and war, it was spring indeed.

IT WAS THE ORANGE-TIP.

For the dormouse, one tiny penetrating note dominated all. He knew that the singer of that note was four-footed. Have you ever heard a cricket’s serenade? It was something like that. Have you ever heard a tree-creeper talking to itself? It was something like that also. He looked down and saw, as he expected, a round fur ball rolling in and out the grass-stems. At times the ball sat up and sniffed. He knew the puny fists and tapering snout at once. It was the shrewmouse. “Shrewmouse!” he cried, “is it time?” But the shrewmouse had crouched to dodge the shadow of a passing bird, and he saw him no more. However, he had seen enough. He stretched his hands and feet as though he would rack them from their sockets. Like Tennyson’s rabbit, he fondled his harmless face in the most elaborate of toilets, then he took one nibble at the remnant of the squirrel’s nut, and dropped off to sleep till the twilight.

BEFORE HIM LAY THE TWILIGHT WORLD HE LOVED.

“FIGURE SOMEWHAT STOUT,” SAYS THE BOOK.

It is time to describe him.

“Figure somewhat stout,” says the book, “a single pair of pre-molars in each jaw, first toe of the fore-foot rudimentary, tail cylindrical,” etc. The dormouse was anything but stout—six months’ fasting, save for half a nut, had effectually restrained any tendency that way. No doubt in other respects he was in fair accordance with museum pattern, but he differed in one essential particular—he was alive.

HIS EYES? NOR PEN NOR CAMERA CAN PRESENT THEM.

His colour? When he had first retired to rest he had closely resembled a young red vole, buff grey all over save for his white waistcoat and the hair-parting along his back and down the ridges of his limbs. This was a delicate auburn. During his sleep the auburn had overspread his back, softened into cream colour on his sides, and thence into a pure white front. Ages ago his ancestors had been white all over; now, amid changed surroundings, the white only lingered where it was least conspicuous.

His eyes? Nor pen nor camera can present them. Imagine a black pearl imprisoning a diamond; imagine a dewdrop trembling on polished jet; add to these beauties life, and you will have the dormouse eye.

His tail? Distichous, say the books. Feathers are mostly distichous, hair-partings are distichous, the moustache is distichous. So is the dormouse tail; but the hairs along it do more than merely part. They curl, upwards from the root, downwards to the point, and form a plume.

The plume is a natural parachute, not so obvious, perhaps, as in the squirrel’s case, but, weight for weight, of equal service.

His feet? Ten toes behind and eight before, sharp-pointed toes that grip the slenderest twig, and catch the slightest foothold in the bark.

His ears? Small, say the books. Not small, but rather hidden in the deep surrounding fur.

Had you seen the dormouse at the moment of his final awakening, you might have recognized him from this description. A few minutes later and the grey, flitting shadow might easily have baffled you. For, as he reached the surface of his nest, the sun went down.

SHARP-POINTED TOES THAT CATCH THE SLIGHTEST FOOTHOLD IN THE BARK.

Before him, at last, lay the twilight world he loved. Nature had ceased her noise and commenced her melody. From the brook below came the dull plash of the rising trout; now and then one could catch a stealthy rustle in the herbage—the beetles were abroad, ay and the mice and the beasts of prey; a hare paced by with easy lilting stride; his gentle footfall hardly stirred the dust. In the distance sounded the cry of a lost soul. It was the barn owl starting on her rounds. The dormouse cowered back until she passed—white—gleaming, swift and silent as a moth.

IT WAS THE SAME SOFT FUR THAT HE HAD NESTLED IN LAST YEAR.

ONCE MORE HE FELT THE MAGIC PULSE OF LIFE WITHIN HIM.

There was no discordant note. Wood, meadow, and hedgerow were bathed in liquid blue. The very tree trunks stood out as indigo against the sky. Daisy and marigold, hyacinth and clover were attuned to the same soothing minor chord. The work-a-day world was at rest, but the sleep-a-day world was holding high revel.

Before he was halfway down the stump he had caught the glint of twenty pairs of eyes. The voles and wood-mice had waited, like himself, until the owl had passed. Before each tuft of grass now stood its latest tenant. From beneath the root of a neighbouring hazel came a stealthy procession of five bank voles. Each, as it gained the entrance, performed its normal round. First it sniffed for weasel, then it sat up and washed its face, then it sniffed again, finally it stole off, foraging among the grass-stems. He saw his friend the shrewmouse scuffling with its mate; he saw the wood-mice nut-grubbing; he saw the night reunion of the stump-tailed voles; but the first of his own kind that he saw was mother.

He had swung himself to the top of a broken twig, and, as he looked down, perceived her climbing stiffly up towards him. Mother had aged since the autumn, but, when she drew closer, he knew her well enough; it was the same soft fur that he had nestled in last year.

Together they went out into the night. Once more he felt the magic pulse of life within him, and ran to the top of the hedge and down again twenty times for the mere joy of running. Head upwards he flew, head downwards, backwards, forwards, sideways. Sometimes he paused for a moment, lightly balanced on a branch end, then swung himself to the next friendly projection. Sometimes there was no pause. In one easy unbroken course he travelled to the end, cleared the intervening gap, and landed on the neighbouring branch below. He never missed, he never stumbled; for he was tumbler and wire-walker and saltimbanque in one.

HE WAITED FOR HER AS LONG AS HE DARED.

And mother? Mother had lost some of her spring, but she had developed judiciousness, and a fine eye for country. It was this latter which, to her son’s amazement, usually kept her two bushes ahead. It was this which made him miss her as the day broke.

He had been to the very topmost pinnacle of a thorn-bush; halfway down he had leapt four feet on to a neighbouring hazel; he had looked back in self-congratulation at the abyss, and, when he had turned again, she had disappeared.

He waited for her as long as he dared, and then crept back subdued and lonely to his nest. Next evening perhaps he would see her again. But the next evening passed, and the next, and the next, and he never saw her again until the end.

Some other time I will tell you how he passed that summer, how he fought for and won a wife, how they built a nest together and made a store together, of the four little dormice, and of the sad fate that befel two of them. Here I can only tell the last scene.

It was late autumn. His wife had already felt the coming of winter, and retired to her six months’ sleep. He himself had sealed her in.

MOTHER WAS CLIMBING PAINFULLY UP TO HIM.

He had taught the two small dormice how to build their nests (honeysuckle fibre and dead leaf), and pointed out the necessity of getting into them before Christmas. He had rebuilt his own nest in the same old hollow, for he knew that he could not hold out much longer.

With every light breeze that crept down the hedgerow now came the rustle of the falling leaf. Each night he had seemed less inclined to wake, and this night he seemed less inclined than ever.

The sun had scarcely set before he felt chilled and uncomfortable. To warm himself he did three minutes’ gymnastics. The end of them found him perched on the same old broken twig, and, when he looked down, even as before, mother was climbing painfully up to him.

It needed but a glance to see that she would not outlive the winter. Had she made a nest? No, she had not troubled. The hole she was in last year would do. Perhaps she would take his nest, he could easily build another. Most certainly she would not. He could help her to put some leaves into hers to-morrow. But that night came the first frost.

BUT THAT NIGHT CAME THE FIRST FROST.

THE PURPLE EMPEROR

Down by the brookside the Sallow drooped her sunburnt leaves despondently. Things were at their dullest.

Three months ago she had been a tree of importance. Her dark, slender branches had formed a fashionable rendez-vous. Each evening she had seen her golden catkins studded with opals—the eyes of soft, furry, blundering moths. Each day the bees had thronged to pay court to her.

Then came Palm Sunday. Her catkins were stripped from her, worn for a few hours in yokels’ hats, and flung aside. The moths came no more; the bees forsook her for the bluebells.

But the kingfishers cared nothing for her appearance. They nested, as usual, deep in the bank below, in a hollow formed by her roots.

The kingfishers were always in a hurry, and their colours were fussy and discordant. They flashed up and down the brook like a pair of demented fireworks. The whole bank reeked with the discarded meals of their progeny.

By the time the nestlings were fledged, the sallow wore its summer mantle, a down-lined cloak of green.

The interesting event had been a diversion. Now there seemed nothing to look forward to.

On the one side lay the meadow-land, stretching in unbroken monotony to the sky-line; on the other, the brook; beyond its wooded bank, more meadow-land.

The brook was not what it had been. Its waters were being drawn away to thirsty London, and herein lay the sallow’s chief vexation.

This year her upper boughs had never flowered. Summer arrived, and she had hoped against hope. They had never even put forth leaves.

To be prematurely bald is disheartening. This baldness was so premature as to be serious. It was the first warning of decay.

The Empress Mother came sailing over the hill, high in the sky as befitted her. Behind her, in the far distance, lay the white-ribbed downs, and, along their ridge, there stretched against the sky a thin, shadowy, broken line. It was the great oak wood, the dominion she had abandoned.

The Empress Mother was looking for a black sallow. Sallows there were in plenty in and about the great wood, but she wanted one all to herself; one fit for an imperial nursery. So she came with unerring instinct to the brook.

The air hung motionless in the grip of a midsummer noon. As she floated earthwards in stately majesty, the sunlight flung its radiance round her, and her broad, white ribbon gleamed on its velvet ground like molten silver.

The sallow humbly drooped her leaves as one who receives royalty.

A SMALL, GREEN-YELLOW, TRANSLUCENT CONE.

For an hour the Empress Mother was busy. The leaves that she honoured were chosen with the nicest discrimination, and she honoured more than a dozen. Each, as she left it, bore on its upper surface a small, green-yellow, shiny, translucent cone, rounded at the top, flat at the base, and ribbed along its sides.

For the rest of the day the sallow held her head high.

There were fourteen eggs in all. Six reached maturity, but we are only concerned with one of them. Outwardly he was much like the others. A day’s exposure softened the yellow of his shell to olive. Save at the base he matched his leaf surroundings to a nicety. The base was suffused with a faint blush of purple. As the days passed the purple darkened to black, and shifted upwards, leaving the parts beneath it pale and colourless. It seemed to struggle towards the sun. On the eighteenth day the shell parted at the summit, and the little Emperor was hatched.

His youthful Majesty was mostly dark brown head. Such body as he could boast of was tapering and greenish. But his head caught the eye. It was well-nigh as large as the egg from which he came. Until he had fed he seemed indifferent to his changed surroundings.

The first thing that he ate was his minute discarded shell, and, from this slender meal, resulted disproportionate energy. He started forthwith on his travels, outwards towards the light as far as he could go. On the leaf point he built himself a pigmy throne of silk; and this was his citadel for a week. He only left it to feed, nibbling the leaf edge jerkily on either side of him. At the week’s end he lost his appetite. His body was now of a decided green—green with the finest powdering of yellow. About his waist the yellow fused into a crescent. Nine of him would have measured an inch.

On the eighth day he ceased feeding altogether. He sat with his hind-quarters anchored to his throne, his head and fore legs raised from off the leaf, rigid and immovable. For three days he grew yellower and yellower. Then his skin split down his back, and he successfully accomplished his first moult. In his short span he passed through many changes, but never one more quaint than this.

During his abstinence he had grown two horns. They branched straight out before him, bristling with short spines, a full third of his length.

He moulted once again before the winter, but this was merely a growing moult. Until October he never left his leaf point. Then Nature herself warned him to seek shelter. The weather was breaking. Rain he did not mind, but wind was different. Suppose his leaf was torn from its socket and hurled a hundred yards into the field?

Leaves were falling all round him, and it was time to take up his winter quarters. He spent a day or two in reaching them, yet they were not far off—merely the junction of his own particular branch to the parent stem. There, in the shelter of the fork, he spun himself a silken blanket, and in it he slept peacefully till April.

Peacefully through everything, and in spite of everything. Rain beat in drenching floods against the sallow, hailstorms lashed her branches, snow enshrouded her, hoar-frost bespangled her,—the little Emperor was quite unmoved. As the bark weathered from ebony to rusty olive, chameleon-like, he changed with it. This was the only outward sign he gave of life.

The catkins bloomed once more, and once more were rudely gathered. With the bursting of the leaf the little Emperor crept from his blanket. He found the world much as he had left it. Only the leaves were covered with soft down, smaller, and easier to bite. He was by now a full half inch in length, big enough to roam at large, and hungry enough to eat the tree. He started on the first leaf he came to, and, in five minutes, had gnawed a neat crescent out of it. There was method in his gnawing. He fixed his claspers firmly to the stalk, then stretched his head as far as he could reach, and nibbled the leaf edge backwards. When his feet reached his claspers, he commenced afresh.

Before the winter he had only fed at night; now he fed from sunrise to sunset, and at night as well. He fattened steadily, and in proportion, growing more slug-like every day. His horns but emphasized the likeness. He carried them well forward, and, at his rare sleeping intervals, they lay flat against the leaf. Thus with his swollen waist he seemed to fall away both ends. Three times he outgrew his coat. Each time he had eaten till it stretched to bursting point. Each time the process of disrobing was the same.

He dragged his slow bulk to some thick mass of leaves, selected the innermost of them, and spun a web of silk upon its surface. From this he hung himself head downwards. His weight helped him, and, in due course, the old skin split along his back, and he emerged resplendent in a fresh, untarnished, elastic livery.

Each moult was marked by some embellishment. Rusty olive gave place to pale sap green, this in turn to the green of the young willow-leaf, and this again to the green of lush grass. Nor was the change in body colour all. His sides in time were decked with slanting stripes of yellow. A V-shaped orange girdle marked his waist. Its buckle was a tiny splotch of crimson. His horns were tipped with russet brown, and head and tail alike were faintly tinged with blue.

Yet, for all his rainbow tints, Nature had decreed that he should live invisible. To this end she had coloured him to match his food plant. The lines of yellow on his sides broke the monotony of green, as veins break the monotony of a leaf. The blue about him was sister to the blue of summer that played amid the foliage with quivering transparent lights and shadows.

Nor did the cunning harmony end here. In form as well as tint he cheated observation. His outline, as he lay at rest, formed the most perfect outline of a twisted leaf.

(L) GROWING MORE SLUG-LIKE EVERY DAY. (R) FOR ALL HIS RAINBOW TINTS, NATURE HAD DECREED THAT HE SHOULD LIVE INVISIBLE.

Birds passed him by unnoticed. Once, and once only, the ichneumon marked him down.

It was after his fifth and final moult. He was just a shade too light for nature, and the ichneumon has a pretty sense of colour. She buzzed viciously through the foliage, and settled for a moment on his back. She had reckoned without her host. His skin was indeed dangerously bright, but it was sensitive in proportion.

Before she could establish herself, a vicious back-sweep of his horns dislodged her.

Again and again she returned to the attack. Could she but pierce the skin, her paralyzing venom would quickly do its work. Then the murderous task would be easy. Eggs would be laid deep in the wound; grubs would hatch from them, and batten luxuriously on their unwilling host, sapping his strength, but cunningly avoiding his vitals, until they were full-fed. As they turned to pupæ he would die, and from caterpillar, or may be chrysalis, there would then issue, in place of gorgeous butterfly, a host of dingy hymenoptera. So would the race of ichneumons be preserved.

The little Emperor was fat and well-liking—an ideal créche for young ichneumons; but the little Emperor was very wide-awake.

The fly could find no foothold on him. He flung his armed head backwards to his tail. He pawed the air with six fore feet. He shook himself in paroxysms of fury. The fly cared little for the latter, but the horns were hard and formidable. They covered his whole body with their sweep, and struck with lightning speed.

At sundown she withdrew discomfited; the little Emperor’s horns had served him well.

His life was uneventful after this. When he had reached a length of two inches, his growth ceased. He fed less ravenously and less frequently. Three parts of his time he spent in contemplation of a special leaf. It was hard to tell wherein lay the fascination. He had spun a silken carpet on it. At rare intervals he tore himself away and snatched a hurried meal, but he infallibly returned to its friendly shelter. He rested on its mid-rib, facing the foot-stalk. His body was strongly arched and so compressed that the ridges of its crowded segments recalled the pile of velvet. His head and fore feet scarcely touched the surface. So he made ready for the second change.

For this even the favourite leaf was discarded. He roamed about the tree for days, seeking one that would suit his purpose. At last he found one, hidden in a thick-set cluster. It hung free, but he secured it in such fashion to its stem that a stiff breeze could hardly shake it. He stretched silken ropes from its edges and passed them completely round the foot-stalk. Then, on its under surface, he spun a little boss of silk, gripped it with his hind-claspers, and swung with easy confidence head downwards. For three days he hung thus motionless, yet within him there was a lively motion.

From the time he left the egg his life had been a dual one. The eye saw nothing but the outward mask, the caterpillar-form. Within this living vehicle that moved and spun and fed, lived the true butterfly—life within life, being within being.

THE CROWDED SEGMENTS OF HIS BODY RECALLED THE PILE OF VELVET.

The caterpillar mask had done its work, and having done its work, must die. Yet one can hardly call such dissolution death. As it hung suspended, all the marvellous mechanism which had formed a moving, eating, spinning, sentient being, was absorbed into the chrysalis it covered. Merely the outer empty shell remained.

ON THE CHRYSALIS HEAD WERE TWO SHORT-POINTED HORNS.

COLOUR AND FORM COMBINED THEIR SKILFUL MIMICRY. ITS FORM THE FORM OF THE SALLOW-LEAF.

On the fourth day this shell split cleanly at the tail, and, from the opening, the hind part of the chrysalis emerged. It jerked from side to side, to all appearance aimlessly. Yet there was method in its madness. A side-swing forced it deep into the boss of silk, and, in a moment, the hooks that studded its extremity were fast entangled. The chrysalis had its point d’appui.

Again the old skin cracked, this time behind the neck. The chrysalis head was free. On it were two short, flattened, pointed horns. A jerky movement of the shoulders followed—first expansion, then contraction. At each expansion the old skin slipped a trifle upwards. Turn by turn the segments of the body did their work, until it lay in gathered folds about the tail, just as the pushed-off stocking lies about the ankle.

But even so, the task was not completed. The skin must be got rid of. Its dull white mass, with dangling skeleton horns, was too conspicuous. Nature had armed the chrysalis with the needful tools, a grip attachment and a set of tiny sharp-edged hooks. The skin was fast entangled in the boss of silk. The chrysalis secured an independent foothold (using as stepping-stone the skin itself), spun itself from side to side, and cut the threads that bound it. It jerked lightly from leaf to leaf, until it reached the ground. The second change was accomplished.
