of the flat hue of skimmed milk--in coconuts and in the cavities of bamboos; but in the production of the real gem neither oyster nor mussel nor pinna need fear the rivalry of anything on the earth's surface. The pearl belongs to the sea.

Completely spherical pearls can be formed only loose in the mantle or soft parts of the body of the animal; but intrusions incite a deposit of nacre in the form of a projection on the interior, which projection, often a mere bubble, but sometimes semi-detached, may take the shape and dimensions of the foreign substance. Or an inoffensive mollusc may be goaded by the piercing of its shell from the exterior to create that for which men venture into the depths of the sea. If a pearl-secreting oyster be inherently robust, its defence against assault from without may consist of the strengthening of the interior at the point of attack by deposits of nacre. Thus, a slight protuberance arises which becomes the base of a blister or button or the starting-point of a pear-shaped gem. Many a lovely gem is, therefore, nothing more than the imperishable record of aggression on the part of a flabby sponge on a resourceful oyster. Occasionally valuable pearls are found within huge blisters. Such pearls originate, no doubt, in the ordinary way, but, becoming an intolerable nuisance on account of increasing size, are confined in nacre.

One of the accompanying illustrations shows the fate which befell an infant chiton upon intrusion on a small black-lip oyster, and coincidentally the origin of a blister. The chiton family being notorious for stolidity, the infant could not have realised the risks of its trespass until the strait-jacket made its retirement impossible. The nacre has reproduced the details of the chiton's exterior with the fidelity of a casting, and further reveals the fact that it was alive when entombed, for its struggles to escape are solidified.

This deliberate act of the oyster may not stand comparison with the stone of Pyrrhus's ring, which had the figure of Apollo and the nine Muses in the veins of it produced by the spontaneous handiwork of Nature without any help from art. The marvellous stone belonged to the fabulous past; the imprisoned chiton to the prosaic present.

Another illustration is that of an accumulation of nacre which has assumed accidental resemblance to a miniature shark. It was found in a gold-lip pearl shell in Torres Straits. The like quantity in globular shape would represent a pearl of great value.


A PEARL IN THE MAKING.

On a calm and luminous day I waded, disrobed, in shallow water as limpid as the fictitious stream which legend says King Solomon improvised at the foot of his throne when the Queen of Sheba attended his court. Lifting her robes--for she imagined the crossing of the water to be a ceremonial device--the gorgeous Queen displayed her shapely calves. The water resting on the verge of the lovely Isle was as delusively clear, but was not deceptive.

It revealed living coral, good to avoid by the barefooted; clams with patterned mantles of various tints--grey, slate-blue, sea-green, brown, and buff; anemones in many shapes, some like spikes of lavender, and irritant and repellent to the touch; some platter-shaped and cobalt-blue; some as living vases with the opalescent tints of Venetian glass, which, abhorring the hand of man, retreat into the sand until only an inconspicuous fringe of neutral tint is visible. Sea-slugs in almost endless form and variety of hue, and many other strange sea things, were among the inhabitants of the reef--a closely packed arena of never-ceasing slaughter.

In the middle of a clump of brown seaweed, which had fallen apart like the neatly dressed hair of a woman, was a black streak, signifying the gape of a wedge-shaped mollusc known as a pinna. The gape was about as long as the parting of a woman's hair and about thrice as wide. As I crouched to note the functions of the animal, my shadow intervened and the caution of the creature was roused, the valves closing so that no sign of the presence of the shell was distinguishable among the slightly wavering, minute particles of alga. Changing my position, so that the pinna might not be deprived of its share of the rays of the sun, the valves soon furtively opened. A slight movement on my part and they closed again, without having revealed any hidden charms.

After a few minutes, a certain confidence being established between us, the pinna emerged from its retirement, in so far as such creatures are permitted by Nature. The mantle of this particular species is shown as a delicate fringe of lace in old gold and black. It ripples along the upper edges of the confining valves, which are intensely black with a pearly lustre. The pretty movements of the mantle--like the swinging of the skirts of a well-apparelled damsel--attracted admiration, and on peering into the shell a glimpse of something precious was obtained.

Tossed and twirled about just below the old gold fringe was a black pearl about the size of a pea. The prize was safe. Without risk of loss it could be watched in its unceasing revolutions. It seemed as if the animal, with automatic perseverance, attempted to eject the incubus, the weight of which kept it about an inch below the aperture of the valves. Such motion would naturally tend to perfection. Whatsoever its lustre, it would certainly be a sphere. Besides, it was a pearl in the making. As long as it remained within the pinna and it could not be voluntarily rejected, its size would inevitably increase. It was the rolling stone to which time and the secretions of the animal would add weight and, peradventure, beauty.

Was mortal ever before privileged to watch over the growth of a black pearl? The activities of the mantle, a blending of enticing colour and poetic motion, were slow, free, and light-attracting. The ancients believed that some pearls were constituted by flashes of lightning playing on bubbles within the oyster. A relative of the family here seemed to be wooing the tropic sun of its beams, if not to vitalise, at least to burnish its treasure.

Close scrutiny showed that the pearl was not absolutely free. It was enclosed in a transparent membrane, the merest film, which confined it to a particular position in the mantle, while it seemed to possess independent actions--vertical and revolutionary. Perhaps the rays of light which fell unequally on it through the water created the illusion of revolutions, but it is certain that the pearl seemed to be playing a game of hide-and-seek.

Was it possible for human nature to deny itself so easily gotten and pretty a prize? I confess, though the possibility of the pearl increasing in size and loveliness was obvious, that the fact that pinnas are subject to ills, chances, and mishaps, was also recognised. Left to be slowly tossed about, the pearl would become greater; but size, though an important feature, is not the only desirable quality. And while it grew might not another barefooted beach-comber discover it? Or might not one of the many unintelligent admirers of the pinna itself find entrance by drilling or by the violent crushing of the valves, and, ignoring the treasure, destroy the organs and the substance by and from which it was being delicately elaborated? Suppose, I argued, I remove the gaping shell, I shall no longer be able to enjoy the rare, the unique pleasure of presiding over the gradual perfection of a pearl, an aesthetic advantage to which I alone had been made free. Could present possession of a little sphere of carbonate of lime, polished and sooty black, compensate for the continuance of the chaste joy of watching one of the most covert and intimate processes of Nature? Balancing the immediate material gain against the inevitable moral loss, I was almost persuaded to self-denial, when, with a sudden impulse, begot of the consciousness of rightful acquisition, the pinna was forcibly yet carefully drawn out of the sand in which it was deeply embedded and in which it was anchored by toughened byssus. Directly the valves were prised apart the pearl fell into my hand. Never before had I seen one so loosely retained within its shell. Generally, in the case of the pinna, pearls are embedded in the muscles or soft parts, and are not primarily discernible, but have to be sought for by passing the "meat" through the fingers. On this occasion all previous experience had been set at naught, so that it might seem that the prize had been presented by the animal as its perfect and most opulent work.


STRANGE PEARLS.

The engaging theory of the ancients that pearls were made of glutinous dewdrops condensed by the sun's heat does not take into account the fact that some of the rarest, though not the most valuable, have assumed contrary and fantastic shape. Fish, crabs, and marine insects have proved a common origin of pearly developments while they have been regarded by some as almost miraculous conceptions on the part of the afflicted mollusc.

Hamed of Jeddah, the stubby Arab who deals in fish and oysters, and who professes to have groped over in his youth a considerable extent of the Red Sea for coral and pearls, relates many experiences in which the popular gem takes pride of place. Oriental that he is, he loves exaggeration, and while lending a propitious car to the stories in which he enshrines his prime, when he could dive deep and long, and when the precious red coral was "thick" and every shell contained a pearl, it is discreet to disregard obvious breaks and bulges along the prim path of truth. The very crudeness of his embellishments invests with kind of comic relief some of his fables, which end invariably with insipid uniformity. All the pearls which have slipped through Hamed's rough hands have been valued at five hundred pounds, never more or less. It is not for me to rub the gilt off the innocent inventions of the emotional Arab, but merely to relate one of his time-beguiling tales, and one which, probably, is of clean-cut truth.

A huge gold-lip, found four fathoms deep, where the sea grass sways indolently long, contained a tinted pearl like:

"That fella sitting down along a tree and sing out along night time."

"Flying fox?" I guessed grimly.

"No!" snapped Hamed indignantly. "'Nother fella."

"That bird which says 'chump, chump, chump?'" I meekly asked.

Again Hamed sneered ironically. "No bird. No bird carn get along oyster. Little fella-green like leaf. Sing out 'Ko-rog, ko-rog, ko-rog!'"

"Oh! Frog!"

"Yes. Like frog. Me call him 'ghouk' along my country. That fella inside gold-lip. One inch long. Leg, hand, mouth, eyes all asame. I bin get five hundred pounds for that fella."

Azure pearls in the similitude of tiny fish can be vouched for by people far more careful of their facts than Hamed--fish which have intruded themselves on the oysters and have been encased in nacre. Probably the rarity which fell into Hamed's hands was the pearly presentment of a crustacean, for marine frogs are infinitely rarer than pearls. Several molluscs admit tenants, one particular species a rotund crab; but in the case in point the wrong mansion was entered and, so to speak, the obtruder was transformed.

A common and neat industry in China is the production of fraudulent pearls, pretty and in accordance with submitted design, in which the co-operation of the obedient but frail mussel is necessary. If a round pearl is desired, a naked shot is introduced between the valves so much to the discomfort of the animal that it proceeds to cover it decently with layer after layer of
