Tendrils

QUITEcontrary to my original intention, my specimen ofMusca domestica, which I had captured at random to serve as my model in the present chapter, has suggested that I begin with a Q, and after some expressive criticism on the matter I have at last consented to humor him, especially as he proved otherwise a most unique and accommodating individual. Being in need of a good, healthy, toe-twisting, neck-twirling specimen to sit for his portrait in an illustration for a forthcoming article on the paper wasp, I cast my eye about my easel. There, right at my elbow, still plying his never-ending toilet, I beheld himâ€”strange coincidence, was it not? A sweep of my hand, and I have him! And in a moment more,with the tips of his toes besmeared with glue, he is a secure prisoner on the white paper before me.The victim having served his purpose, I was preparing to drench him with a few drops of water to dissolve his bonds and set him free, when I happened to observe a feature which had before escaped my notice. The glue had chanced to secure one of its feet well beneath its body, and now that it was released I discovered that I had made considerably more of a catch with that sweep of my hand than I had imagined. Attached to one of the terminal joints of the front leg there appeared a tiny red object, which I instantly recognized as a curious tag which I had seen before, and which forms an occasional lively episode in the life not only of house-flies but other flies as well. And what a queer-shaped tag it is, to be sure! It is not easy to describe its dimensions on account of its changeable proportionsâ€”now spreading out its two long appendages, now contracting into an oblong or rounded outline, or sprawled out in the shape of a curious letter T, and now thrown about in such a helter-skelter fashion by the antics of the fly that nothingbut the fact of its red color is discernible. But when we bring our magnifying-glass to bear upon it, its diminutive size is forgotten, while its shape is now perfectly familiar to us allâ€”a lobster! a veritable live young lobster, and what is even more strange, a live boiled lobster at that! No, it must be a crab lobster, for was ever the liveliest lobster in its greenest stages half so spry as this warlike midge, whose free, upraised, open claws threaten to nip our fingers off as we hold the lens above him. But nag and prod him as we will, no provocation will induce him to loosen his grip on his means of transport.

For how many days, I wonder, has he been on this particular flying trip? How many miles has he travelled, and what varied experiences has he survived! How many are the lumps of sugar, the drops of molasses, the slices of bread, and pats of butter over which he has been trailed, to say nothing of puddles of fresh ink! And then think of the many hours in which, from his present position, he must have conspicuously figured at that toe-twisting toilet of his host! Fancy brushing your coat and combing your hair with a live boiled lobster!But pollen grains are not pumpkins and footballs and tea-boxes, as the microscope would have us believe; nor does the drop of water contain a herd of strange elephants. Can it be possiblethat this lobster is, after all, only about an eighth of an inch long, with its claws spreading barely three-sixteenths of an inch? Yes, true; but we must remember that the fly is only about one-third of an inch long, and we can imagine how proportionately formidable the little beast must appear as a lurking foe and a handicap to the fly fraternity. I have therefore pictured this little episode of fly-time somewhat from the aspect of the fly. This was one of the "troubles" which I had in mind as I prepared the initial design with its letter O. I had counted on using an old specimen of the lobster which I had safely stowed away in a pill-box somewhere, until my haphazard fly victim supplied me with a fresh specimen, and subsequently helped me out in the completion and modification of my initial.

A correct idea of the anatomy of the little crab may be obtained from my illustration. But what is it all about, this funny ride on a fly's hind-leg? Excepting as an inconvenience and encumbrance it is doubtful whether the fly is much the worse for his close attachment, and while this mimic crab or lobster cannot be called a frequent passenger, a careful scrutiny of any considerable assemblage of flies on white paper or window-pane will occasionally show us the animated and persistent red tag.

But let us call him a lobster no more, rather one of the "False Scorpions," one of the groupknown asPedipalpi, in the books: queer little creatures that live in dusty nooks, among old books and papers, and feed on tiny mites and other minute life which harbor them, but born rovers withal, with a singular fancy for fly-toes and free rides.

But the false scorpion may be considered rather as a bother than a serious trouble to the fly. His real troubles are too numerous to mention. His life, as most of my readers will be glad to learn, is not a bed of roses, as is commonly supposed. Just think for a moment what a fly's existence must be. With the deadly fly-paper on the one hand, the continual danger of being cemented into a pellet of pulp in the maw of a hornet, or impaled on the beak of his murderous relative the "Laphria-fly," or snapped up by birds, toads, snakes, he certainly has abundant use for that head full of eyes of his. All summer long heruns the gantlet of risks like these, but in September and October a new and terrible danger awaits him, and fortunate is he if he escapes in these advanced days of scientific discovery, when so many of our mortal ills are shown to be dependent upon the malignity of hovering germs, of microbes, bacteria, and bacilli.

Let us be thankful we have at least escaped the notice of one of this insidious throng, and are spared the grotesque horror of such a fate as the germ-scourge of flydom. How swift and terrible is its course! Today a pert and gladsome innocent, sipping on the rim of our dinner-plate; to-morrow a pale, dry relic of his former self, hanging from the window-pane by its tongue, and enveloped in a white shroud of mould, the victim of a germ or spore. Look where we will upon the window on those September and October days and we see the little smoky cloud with the dangling fly in its midst, and many an apparently modest and considerate fly upon the wall will be found similarly fixed to the surface, and surrounded with the white nimbus.

But the real mischief was done perhaps early in the evening, after our fly had retired for the night. He presumably experienced the first attack of acute dyspepsia he had ever known. In his promiscuous feeding he had chanced to imbibe a spore, which once within his vitals began its murderouswork, growing so fast as to completely fill his swelling body by morning, when, having completed its growth and penetrated through the insect's skin, it spread its own spores, to be wafted hither and yon to the peril of next year's flies, and the consequent delight of the tidy house-keeper.

Such is the work of the world-renowned fly-fungus, of which a writer says: "It silences more house-flies than all the brushes, traps, poisons, whacks, and swearing devoted to the extermination of the insect."

CARELESSobservation of Nature is responsible for some curious misrepresentations of her most simple facts. Even those of us who stand somewhat in the relation of nature teachersâ€”namely, artists, both draughtsmen and painters, and from whom we have a right to expect absolute fidelityâ€”are not free from our shortcomings as truthful chroniclers. Thus how often we see otherwise beautiful landscapes marred by features which rebel against all laws of natural philosophyâ€”of a storm sky above a sunlit scene, for instance, spanned by the arc of the rainbow, and with all the shadows of trees and other objects thrownsidewise! Then there is that inverted or very "dry" crescent moon in western twilight skies; and how seldom do we see the beautiful law of the twining tendril appreciated in the most careful design of the botanical draughtsman!For years the tendril was to me the conventional spiral, twisting like a continuous curl or spring from the parent branch to the support within its clasp; and it is safe to assert that not one inâ€”well, a good many of us, who should have gone out to our grape-vine or passion-vine or melon-patch, without a previous forewarning, would have been able to tell correctly the pretty little story of its tendril methods, or have even noted the curious little kink which is the infallible peculiarity of the climbing tendril.

Whatisa tendrilâ€”botanically speaking? That depends. It is one thing in this plant, quite anotherin that, so students of vegetable anatomy or morphology soon discover.

It is soon perfectly plain that the stem is a modified root. For instance, plants have been taken up from the sod and replaced in the ground upsidedown, the roots subsequently becoming stems, and bearing leaves, and the buried leafy stems assuming the functions of roots. Leaves are mere modified branches, and the flowers modified leaves. Pistils and stamens in flowers are modified petals, or rather petals are modified stamens, the "doubling" of flowers representing the being thus accomplished, while the petals again are mere changed leaves. A neighbor of mine has a bush bearing green rosesâ€”all leaves. In the water-lily you will find it difficult to determine just where the stamen ends and the petals begin, so gradual is the blending. In the peony the same is true, and carried still further in the merging of petals and calyx into the approximate leaves.

And so it is with tendrils. In certain plants the point of the leaf, through ages of "natural selection," has gradually been prolonged into a slender arm, which clasps the branches of trees, and enables the plant thus endowed to climb higher to sun and sky, and thus to thrive more vigorously than its less fortunate brothers. The plant so advantageously equipped transmits itstendency to its offspring, and has therefore survived in place of its ancient fellows, and is the type perpetuated or "selected" by nature. Such a tendril, then, is a modified leaf. How is it in the pea? Here we find four leaflets in two opposite pairs, butno odd leafletat the end of the main stalk, such as we see in almost all other plants of its family. But in place of this leaflet we find a branching tendril reaching out on all sides for conquest. How quietly by the aid of these eager arms the sweet-pea climbs to the top of its brush! In the common catbrier or smilax we see two slender thread-like tendrils growing from the base of each leaf. Here we have another modification, a development of the "stipule," that tiny pointed growth common to many leaves, and particularly notable at the base of a rose leaf. Still another plan has been evolved in the grape-vine. If weexamine our grape arbor in June we find a number of drooping, swaying branches. The leaves are scattered singly at intervals of a few inches along the branch, each of the upper ones being attended on its opposite side by a drooping cluster of mignonette-scented blossoms. Thus they follow down towards the tip of the branch, where the clusters suddenly cease, and are replaced by long, slender, curving and branched tendrils, sometimes ten inches long. We might thus reasonably assume the tendril in this case to be a modified blossom cluster, but there is no need for us ever to assume such a thing. If we will only search with sufficient care we shall at last discover the absolute proof of the fact in a tendril which is partly in blossom, the nearest leaf-joint above it having a full cluster of blossoms, and the tendril below it, nearer the tip, not a few scattered flower-buds at its tips. This grape-vine instance may be taken as a demonstration that in no case is the tendril a special or primal organ, but merely an old one adapted to a new purpose. In one instance from a leaf, in another from a flower-stalk, just which can generally be determined by a sufficient search for the telltaleintermediate formsomewhere to be found on the plant.

Among the most beautiful of all tendrils are those of the passion-flower and plants of the melon family, notably the wild star-cucumber,whose portrait is here presented. It is a more or less common weed, to be found about gardens and barn-yards, where it covers the fences with its profuse, clambering growth, its stalks everywhere entangled or drawn close to support by theirlong, green, spiral springs, and its free, branching, young tendril tips reaching out in all directions for fresh foothold, and in its absence content at length with a friendly intertwining among themselves, and a consequent tangle of green convolutions. It is hard to believe that these long, outreaching arms at the summit of this vine are identical with the closely twisted spirals below, but such is the case; let any one of them once feel the contact of even the frailest support of twig or stalk, and it is soon close in the embrace of its eager tip, and the contraction of the spring commences, but the method of this contraction is worth our study.

In order for this tendril to coil it musttwist, and it is perfectly plain on general principles that with both ends held fast twisting is impossible. But this little paradox is evidently dismissed by the tendril. If we tie a short string between two given points, and attempt to twist it with our finger and thumb, we succeed in turning the string, 'tis true, but the twist on the right side neutralizes that on the left, being in the opposite direction. In this way only can the cord be twisted. If we twist with sufficient patience we may imitate the coil of the tendril, which is performed precisely in this way. Herein lies the secret of that little loop or kink in the centre of all tendrilsâ€”a given point, which cannot be determined on theextended tendril, but whose mission is toreversethe twist in opposite directions as soon as the tip has secured its contact, and thus permit the coiling process to proceed. In tendrils of exceeding length several of these reverse loops may be found at regular intervals, sometimes as many as six in a single tendril, but the coiling process usually awaits this contact. Unsatisfied tendrils of the grape, for instance, will remain unchanged through the entire season, or until their sensitive touch has been lost. Others, like those of the passion-flower, will occasionally become discouraged and curl up all by themselves, in which case, the other tip being free, the curl is perfect and continuous and without the reverse loop, which is now unnecessary. But the function of the tendril is to clasp and hold. Its growth is not complete until thus quickened by the new responsibility. Tendrils on duty become tough and sinewy in comparison to their idling neighbors. How firm and rigid are these swollen coils upon the grape-vine!We do not gather "figs from thistles," but some equally incongruous botanical associates are sometimes brought about through the insinuating and clambering methods of the tendril. Have we not all seen apple-trees bearing pumpkins or squashes or gourds, all originally carried thither in the form of great yellow blossoms or tender shoots! Thegrape-vine occasionally plays a singular botanical prank in the orchard. Here is a drooping tendril which has been swinging about for weeks from its vine canopy on the old apple-tree. It had become almost discouraged, when a chance-favoring breeze wafted its tip in contact with an apple close by. It was its last chance; with its hooked extremity it clasped the stem of the fruit, and soon made itself fast with three or four firm coils. Doubtless the little reversing loop somewhere along the tendril was also awakened from its chronic lethargy, and did its best tostart the coil. Presumably it succeeded, for the pull was sufficient to dislodge the apple, which, falling to the entire length of the tendril, was still held fast in the grip, whose new responsibility had given it new strength.And there our apple hung for weeks, swinging like a pendulum from the slender grape-vine, the coils on duty still keeping their firm grip on the stem, even though all above were straightened by the weight of the burden.

AFEWdays ago, while returning from a walk, I chanced to observe a dead grasshopper upon the dirt at the side of the road. Now this incident would not have been of special importance had I not discovered, upon carefulpost-mortemexamination, the very remarkable manner of the insect's death, which recalled a similar surprising episode of several years ago which I had almost forgotten. Upon referring to my note-book of that period, however, I found considerable space devoted to the incident, which greatly astonished me at the time. Inasmuch as it presents in a startling light the wonderful and strange resources by which nature holds in check the too rapid increase of species and maintains the great law of equilibrium among the insect forces, it is wellworth recalling in these pages, in the firm belief that my young entomological readers will henceforth look more compassionately and tenderly upon the poor "high-elbowed grig" who is the unfortunate hero of my story. He is familiar to us all, that hovering "rattler" above the hot, dusty road of August, flying up from nowhere beneath our feet in the path, fluttering like a yellow moth, and always disappearing before our eyes when he alights. He is also known as the "Quaker," from his drab suit and bonnet, and his generosity with his "molasses" is proverbial from the days of the Pilgrim settlers. Who would have believed that such a fate as the following lay in store for him.

In previous papers I have indicated some of the remarkable pranks which the various ichneumon-flies play with unsuspecting caterpillars. The polyphemus, for instance, whose cocoon, filled with hopes of a beautiful butterfly existence, yields only a swarm of wasps. The caterpillars are helpless, and would seem an easy prey to the wily fly who lays her eggs upon them; but even the agile-winged "Quaker," and doubtless many of his kindâ€”yes, and still more agile insectsâ€”are not quick enough to escape a like fate.

At the time of my discovery I had in preparation an article for "Harper's Magazine" entitled "Among Our Footprints." I wished to describeand illustrate a singular battle which I had shortly before observed between a large red mutilla ant and a "Quaker." The mutilla I had captured at the time, and had preserved as a specimen. I needed only the grasshopper to complete my drawing. Directly in front of my city house a number of vacant grassy lots offered a favorite haunt for the insectsâ€”I used to call it the Quaker camp-meeting groundâ€”and I started out to procure one. Having no net, I was soon convinced that I was greatly at a disadvantage. The thermometer was about 90Â°, and, of course, the "Quakers," being in their element, had much the best, not to say the easiest, time of it. I at length gave up the chase, and was about leaving the field, when fortune favored me by the discovery of a clumsy specimen, which seemed unable to flyfor any great length, and he was soon captured. Upon examination his wings seemed partially paralyzed, but otherwise he appeared to be in good health and spirits, his hind legs being especially lively and snappy. I immediately took the insect to my studio, and pinned him through the thorax. He was strong enough to pull out the pin from the board and jump around the room with it in my temporary absence.

I lost no time in taking his portrait, which figured in the illustration to the article on "Footprints" as "the ungainly victim," I little dreaming when I gave him such a title what a remarkable sort of victim he even then was. The drawing took me about ten minutes. I then left the studio, and was absent precisely fifteen minutes. Upon returning I found the grasshopper dead.

My curiosity was aroused, not only by such a rapid demise (for the impaling through the thorax is not usually an immediately fatal injury to an insect), but especially by some very strange and unnatural automatic movements of the victimâ€”head protruding and turning from side to side; queer expansion of body, as though breathing; unusual lifting and other motions of legs, particularly of hind legs; the whole demonstration a mockery on life. The grasshopper was pinned to my drawing-board, and against a piece of newspaper.As I watched his strange antics, I suddenly discovered that he had become a veritable phantom of his former self; that I could actuallyread the newspaper text through his body. Examination now revealed the mystery. I could easily see every nook and cranny of the grasshopper's interior, so glassy were the walls of the body, and I could now count about a dozen small, white larvÃ¦, which were now full grown, and were crawling about within through head, thorax, body, and hind legs, cleaning its walls of every particle of remaining tissue, and causing the singular motions described. Such a strange house-cleaning I never saw before.

When the "Quaker" locust was captured it showed not the slightest sign of any such goings-on within its being. The final voracity of the larvÃ¦ was swift and terrible. And what an astonishing instinct is that which should teach these parasites to avoid the vitals of their insect host until the last moments of their own final, complete growth! The entire space of time from the activity of the grasshopper to the empty, transparent phantom was less than thirty minutes. I placed the unfortunate victim in a small, close box. Next morning he presented nothing but a clean, glassy shell, now more glassy than before, empty of every vestige of organic matter, whilescattered about on the bottom of the box lay fifteen dark red, egg-shaped chrysalides of the escaped larvÃ¦. Two weeks later, upon opening the box, a swarm of flies flew out. I was enabled to keep two of them. They were almost exactly like the common house-fly to the ordinary observer, but belonged to a distinct genus. At this writing, in the absence of my specimen, I cannot give the name by which they are known in learned circles, but I think I am safe in saying that they probably belong to the group calledTachina, a family of parasitic flies which spend their early lives in a similar questionable manner, to the probable discomfort of potato-bugs, caterpillars, and other accommodating insect hosts.

I had seen similar flies emerging from my caterpillar boxes in my early entomological days without suspecting their significance, and any large collection of caterpillars in confinement is likely to include a victim.

INDEED, are they not all riddles? Where is the flower which even to the most devoted of us has yet confided all its mysteries? In comparison with the insight of the earlier botanists, we have surely come much closer to the flowers, and they have imparted many of their secrets to us. Through the inspired vision of Sprengel, Darwin, and their followers we have learned something of their meaning, in addition to the knowledge of their structure, which comprised the end and aim of the study of those early scholars, LinnÃ¦us, Lindley, Jussieu, and De Candolle. To these and other eminent worthies in botany we owe much of our knowledge ofhowthe flowers are made, and of the classification based upon this structure, but if thesegreat savants had been asked, "You have shown us that itis so, butwhyis it thus?" they could only have replied, "We know not; we only know that an all-wise Providence has so ordained and created it."Take this little collection, which I have here presented, of stamens and petals selected at random from common blossoms. What inexplicable riddles to the botanist of a hundred years ago, even of sixty years ago! For not until that timewas their significance fully understood; and yet each of these presents but one of several equally puzzling features in the same flowers from which they were taken.In that first anther, for example, why those pores at the tip of the cells, instead of the usual slits at the sides, and why that pair of horns at the back? And the next one, with longer tubes, and the same two horns besides! Then there is that queer specimen with flapping earsâ€”one of six from the barberry blossom; and the pointed, arrow-headed individual with a long plume from its apex; and the curved C-shaped specimenâ€”one of a pair of twins which hide beneath the hood of the sage blossom. The lily anther, which comes last, is poised in the centre. Why? What puzzles to the mere botanist! for it is because these eminent scholarswere merebotanistsâ€”students and chroniclers of the structural facts of flowersâ€”that this revelation of the truth about these blossom features was withheld from them. It was not until they had become philosophers and true seers, not until they sought the divine significance, the reason, which lay behind or beneath these facts, that the flowers disclosed their mysteries to them.

Look at that random row of petals, too!â€”one with a peacock's eye, two others with dark spots, and next the queer-fingered petal of the mignonette,followed by one of that queer couple of the monk's-hood blossom which no one ever sees unless he tears the flower hood to pieces. We all know the nasturtium, but have we thought to ask it why these petals have such a deep crimson or orange colored spot, and why each one is so beautifully fringed at the edge of its stalk?

These are but a dozen of the millions of similar challenges, riddles, puzzles, which the commonest flowers of field and garden present to us; and yet we claim to "know" our nasturtium, our pink, our monk's-hood larkspur, our daisy, and violet!

No; we must bemorethan "botanists" before we can hope to understand the flowers, with their endless, infinite variety of form, color, and fragrance.

It was not until the flowers were studied in connection with the insects which visit them that the true secret of these puzzling features became suspected.

We all know, or should know, that the anther in flowers secretes and releases the pollen. For years even the utility of this pollen was a mystery. Not until the year 1682 was its purpose guessed, when Nehemias Grew, an English botanist, discovered that unless its grains reached the stigma in the flower no seed would be produced (Diagram A). But the people refused to believethis, and it was not until fifty years later that Grew's statement was fully accepted, and then only because the great LinnÃ¦us assured the world that itwastrue. But about fifty years later another botanist in Germany, Sprengel, made the discovery that the flower could not be fertilized as these botanists had claimed, that in many blossoms the pollen could not fall on the stigma.

Diagram A & B

Sprengel knew that this pollen must reach the stigma, but showed that in most flowers it could not do so byitself. He saw that insects were always working in the flowers, and that their hairy bodies were generally covered with pollen, and in this way pollen grainswerecontinually carried to the stigma, as they could easily be in these two blossoms shown at Diagram B. Sprengel then announced to the world his theoryâ€”the dawn of discovery, the beginning ofthe solution of all these floral riddles. Theinsectexplained it all. The bright colors and fragrance were intended to attract him, and the nectar to reward him, and while thus sipping he conveyed the pollen to the stigma and fertilized the flower.

Diagram C & D

But now Sprengel himself was met with most discouraging opposition to his theory, showing that he had guessed but half the secret after all. Flowers by the hundreds were brought to his notice, like that shown in Diagram C, in which the insect couldnottransfer the pollen from anther to stigma, as the stigma is closed when the pollen is ripe, and like that in Diagram D, which does not open until the pollen is shed. For seventy years this astonishing fact puzzled the world, and was at last solved by the great Darwin, who showed that nearly all flowers shun their own pollen, and are so constructed, by thousandsof singular devices, that theinsectshall bring to each thepollen of another flowerof the same species, and thus effect what is known ascross-fertilization.

We must then look at all flowers as expressions of welcome to some insectâ€”day-flowering blossoms mostly to bees and butterflies, and night-bloomers to moths. And not only expressions of welcome, but each with some perfect little plan of its own to make this insect guest the bearer of its pollen to the stigma of another flower of the same species. And how endless are the plans and devices to insure this beautiful scheme! Some flowers make it certain by keeping the stigma closed tight until all its pollen is shed; others place the anther so far away from the stigma as to make pollen contact impossible; others actually imprison these pollen-bringing insects until they can send them away with fresh pollen all over their bodies.

Take almost any flower we chance to meet, and it will show us a mystery of form which the insect alone can explain.

Here is one, growing just outside my doorâ€”a blossom "known" even to every child, and certainly to every reader of the "Round Table"â€”the pretty bluets, or Houstonia, whose galaxy of white or blue stars tints whole spring meadows like a light snowfall. We have "known" it allour lives. Perhaps we may have chanced to observe that the flowers are not all constructed alike, but the chances are that we haveseenthemall our liveswithout discovering this fact. If we pluck a few from this dense cluster beside the path, we observe that the throat of each is swollen larger than the tube beneath, and is almost closed by four tiny yellow anthers(Fig. 1). The next and the next clump may show us similar flowers; but after a little search we are sure of finding a cluster in which a new form appears, as shown in Fig. 2, in which the anthers at the opening are missing, and their place supplied with a little forked stigma! The tube below is larger than the first flower for about two-thirds its length, when it suddenly contracts, and if we cut it open we find the four anthers secreted near the wide base of the tube. What does it mean, this riddle of the bluets? For hundreds of years it puzzled the early botanists, only finally to be solved by Darwin. This is simply the little plan which the Houstonia has perfected to insure its cross-fertilization by an insect, to compel an insect to carry its pollen from one flower and deposit it upon the stigma of another. Once realizing this as the secret, we can readily see how perfectly the intention is fulfilled.

In order to make it clear I have drawn a progressive series of pictures which hardly requiredescription. The flowers are visited by small bees, butterflies, and other insects. At the left is an insect just alighting on a clump of the blossoms of the high-anther form indicated below it. The black probe represents the insect's tongue, which, as it seeks the nectar at the bottom of the tube, gets dusted at its thickened top with the pollen from the anthers. We next see the insect flying away, the probe beneath indicating the condition of its tongue. It next alights on clump No. 2, in which the flowers happen to be of the high-stigma form, as shown below. The tongue now being inserted, brings the pollen against the high stigma, and fertilizes the flower, while at the same time its tip comes in contact with the low anthers, and gets pollen from them. We next see the insect flying to clump No. 3, the condition of its tongue being shown below. Clump No. 3 happens to be of the first low-stigma form of flowers, and as the tongue is inserted the pollen at its tip is carried directly to the low stigma, andthisflower is fertilized from the pollen from the anthers on the same level in the previous flower. And thus the riddle is solved by the insect. From clump to clump he flies, and through his help each one of the pale blue blooms is sure to get its food, each flower fertilized by the pollen of another.

1st Clump.â€”Flower enlarged. Insect's Tongue inserted.Pollen high on Insect's Tongue after withdrawal from Blossom.2d Clump.â€”Flower enlarged. Pollen thrust against high Stigma at top and touching Pollen below.Pollen at Base of Insect's Tongue after withdrawal from Blossom.3d Clump.â€”Flower enlarged. Pollen thrust against low Stigma.

Another beautiful provision is seen in the differencein size of the pollen-grain of the two flowers, those of the high anthers being much larger than those from the lower anthers. These larger grains are intended for the high stigma, which they are sure of reaching, while those of smaller size, on the top of the tongue, which should happen to be wiped off on the high stigma, are too small to be effective for fertilization.

UNDERone guise or another the fickle goddess Fortuna would seem to have established her infallible interpreters or mediators. The lovelorn maiden with the daisy, its petals falling beneath her questioning finger-tips to the alternate refrain, "He loves me. He loves me not," is a sacrificial episode in the life of the daisy wherever it grows.The still younger maiden with her dandelion ball, whose feathered parachutes must be dislodged upon the breeze with three puffs from her little puckered mouth, with all sorts of fate depending upon the odd or even number of the remnant seeds, is as universal as the dandelion itself, while the more homely symbols of wish-bone, horseshoe, or horsechestnut,as we all know, are proverbially potent as personal or household charms against ill luck. I once knew a shrewd countryman who gave all the credit of his success in "tradin'" to the "hoss-chestnut" which he carried in his pocket, and would as soon think of throwing his money away as to "drive a trade" without it. More than one old "down-East" dame "sets gre't store" by the horseshoe hung above her doorway, always secured ends up, "so's the luck can't run out." Then there was old Aunt Huldy, who, while she claimed to locate springs and wells the country round by her witch-hazel divining-rod, never ventured upon these expeditions without the concealed necklace of dried star puff-balls hung about her neck.

But perhaps the most universal of all these natural symbols of good-fortune is to be found in the four-leaved clover, almost a world-wide superstition, and traced back to the ancient astrologers. "If a man, walking the fields," writes one of them, "finds any four-leaved grasse, he shall in a short while after finde some good thing."

The clover was considered as being especially "noisome to witches," and the "holy trefoil charm" was a powerful spell against their harm; the "trefoil" being the most widely used title of the cloverâ€”Trifolium, as it is in the botanyâ€”three leaved. And such itshouldbe, to be true to its christening.But it frequently takes exception to the botany and gives us an extra leaf, and thus we have our "four-leaved clover," a rarity which many of us, seek as we will, have never yet been able to discover in its native haunt, even though a whole handful of them are plucked here and there before our eyes by our more favored companions. Indeed, there are some lucky folk who seem literally to stumble upon "four-leaved grasse" wherever they goâ€”who, having found one leaf, will sit down quietly in the grass and ere long accumulate a bouquet.

Yes, here's the secret: It is not your eager gadding quest that gets your four-leaved clover. Nor is it all a matter of "sharp eyes." There is a "knack" about finding four-leaved clover, and this very knack of the so-called "lucky ones," implying as it does the operation of quest, observation, and common-sense, would logically argue a corresponding fulfilment of success in the affairs of daily life. For the observant clover-hunter, if his mind and eye work together, soon learns that the "four-leaved" variety is fond of company, and that the whim of the plant which thus produces one such leaf is very apt to be humored in several others. Thus, having discernedonefour-leaved clover, we assume atendencyin the parent plant, which further search often discloses, sometimes to our great surprise, and, if we are as superstitiousas our antique philosopher above quoted, to our unbounded satisfaction. If, for instance, this one extra leaflet brings such assurance of "good things" to come, what shall be said of a leaf with five or six leafletsâ€”yes, seven, or perhaps eightâ€”I might even add nineâ€”a veritable little green rose of clover leaves, all on one stem, a stem which is sometimes plainly composite, of two or three adherent stems? All of these exuberant forms are to be found with diligent search, and often in the same close vicinity. Nor are these all the varied freaks which the plant will disclose for the seeking. Perhaps you may chance upon that four-leaved variety in which the extra leaflet stands upright in the midst of the three, and is transformed into a tapering cup. These elfin goblets are not exceedingly rare. Occasionally we may chance to find two of these supported by one or two perfect leaflets at the base. Or, if we are especially fortunate, our "good health" may be offered in three of the tiny beakers, not mereapparentcups, but with the edges of the goblets completely united, and which might be filled to the brim with dew.

A collection of the natural whims of the clover, both red and white, would make an interesting leaflet in our herbarium. In the hands of the floriculturist who should cultivate these eccentricities most remarkable varieties of clover mightensue. Fancy a clover plant with every leaf a cluster of tiny cups, or of leaves so doubled as to appear like green roses! Here is a chance for our boys and girls to experiment, and without much real labor, too. Both the red and white clovers are perennialâ€”that is, they come up year after year from the same root. A plant which this year favors the "four-leaf" will doubtless follow the same example next year, and the seed from its flowers might also inherit and transmit the same peculiarity,possibly in an exaggerated degree; and careful selection from year to year, keeping the plants in a corner by themselves, might lead to some interesting results, especially if the tendency were further stimulated by enrichment of soil, to which the clover responds vigorously.

My experience with "clover luck" has been considerable. I believe I have found almost every possible eccentric combination of which the plant is naturally capable, a few of which I have here pictured.

My best success has been met in the "rowen" fields, or the growth after mowing, the energy of the plant, thus pruned as it were in its prime, finding immediate expression in an exuberance of luxuriant foliage, which, I think, inclines to a multiplication of leaves. I once sat down beside such a clump upon which I had discovered a single "four-leaf," and by dint of plucking and examining every leaf in the cluster, succeeded in obtaining thirty-nine specimens. "Why not make it forty while you are about it?" a friend of mine recently remarked, with evident incredulity. Well, Itriedto, but after grubbing up the last embryo leaf at the ground, thirty-nine was my limitâ€”all from one plant. The collection might be subdivided as follows: Four leaves, 22; five leaves, 7; six leaves, 3;seven leaves, 1; nine leaves, 1; cups and leaves, various, 5.At another time I spied a single five-leaved in a dense bed of rowen clover at the road-side, and seating myself close beside it, calculating on this habit of the plant, I vowed I would not get up until I had collected forty multiple leaves. I soon obtained more than this number.The clover-leaf quest is a good eye-sharpener. Which of our boys can show us the best record?I wonder if any of my young readers have ever seen how the clover says its prayers and goes to sleep, with its two side leaflets folded together like reverent palms, and the terminal leaflet bowed above them? So the normal leaf spends the night in the dews. I often wonder what arrangement of adjustment is arrived at when so many leaflets conspire to confuse.My clover-hunting has been confined to the red and white clovers, both species having commontendencies. In the red, the leaves being larger, the freaks are more conspicuous, but the cup forms seem more commonly identified with the white clover.

ONEwho is unfamiliar with the remarkable doings of blossoms in association with their insect honey-sippers might consider it somewhat surprising to attribute "manners" to a flower. But who that has seen the sage-blossom clap its bee visitor on the back as she ushers him in at the threshold of her purple door, marking him for her own with her dab of yellow pollen as she almost pushes him into the nectar feast within; who that has witnessed the almost roguish demonstration which the tiny andromeda-bell extends to the sipping bee at its doorwayâ€”who that has seen these can any longer doubt that blossoms have "manners" as well as we bigger, more consciousbeings? Yes, manners, unquestionablyâ€”"bad manners," it would almost seem, in some instances, as, for example, in this andromeda blossom-bell, which, in its perfume and its nectar, deliberately invites the tinyAndrenabee, only to deluge its little, black, hairy face with a smothering shower of dusty pollen. A remarkable style of etiquette, surely, that is, from ourhumanstandpoint. But in the realm of Flora the standards of decorum, so far as greeting is concerned, are not governed by artificial whim. There is no "smart set" to dictate and set the fashion for others less smart to follow. Each individual flower is a law unto itself as to the method of its greeting to its especial insect friend. The blossom etiquette of welcome is literally as "old as the hills," and has come down with little change from an ancestry which dates back perhaps to a period when there were no human "ancestors" on the globe. So these "manners" are natural and original, to say the least, even if they are so queer sometimes. What would you think of a friend whose hospitable smile and welcome at his doorway should invite you thither only that your foot might touch a trigger and let fall the floor beneath you, while at the same time you are half suffocated with an explosion of a bushel of yellow corn meal? Yet such is something like the spectacular reception which the lotus clover, the desmodium,and the genista flowers consider the most expressive form of welcome. But the little bees seem to enjoy it, and go again and again to each successive flower, well knowing what the result will be, and apparently "touching off the trigger" without a tremor, or even holding their breath. But they and their foreparents for thousands of years have got accustomed to it, and I half imagine that the baby bee, even in his first visit to one of these blossoms, knows precisely what will happen. Pop! pop! go the exploding flowers, one after the other, at each touch of the bee, throwing up a cloud of yellow pollen which covers the bodies of the insects until they are as dusty as little millers.

There is an endless variety in these various welcomes among the flowers, and our barberry has one of the queerest of them all. Poets of all ages have loved to dwell upon the flowersâ€”their "swete smels," exquisite forms, fragrance, and colors. The droning bees in an environment of fragrant bloom have moved many a poetic pen to inspiration. But it is not often that the bards have seen deep enough into the floral mysteries to immortalize thedoingsof the blossoms.

I recall one such allusion, however, with reference to this mischievous blossom of the barberry. How well old Hosea Biglow knew its pranks!
