FISHING FOR PEARLS.

Pearls differ from any other kind of precious gems in requiring no aid

from art to bring out their beauty. While diamonds and sapphires and

rubies require to be cut and polished before they flash forth their

lustrous light, pearls may be said to be ready-made wherever they are

found.

Those who wear and admire them probably give little thought to the

circumstances attending their production and collection; but there are

few industries more interesting than that of ‘fishing’ for pearls,

as practised in the most important pearl-producing districts. Pearls

of an inferior quality to that of the true Oriental are found in a

species of fresh-water mussel inhabiting Britain and other temperate

countries: an important field for their production is being developed

on the coasts of Queensland and Western Australia; and at the Cape of

Good Hope specimens are occasionally found. But the great centres of

the industry are the banks around the south and west coasts of the

island of Ceylon, from which districts all the most celebrated pearls

have been derived. The banks or _paars_ there are under government

supervision, and fishing is only allowed under the immediate inspection

of the officials, who issue stringent regulations on the subject.

For some years the produce of the _paars_ has been falling off, and a

series of experiments has recently been carried out, and is now in

course of completion, with the object of discovering whether, instead

of allowing them to be fished every year, an interval of one, two, or

three years between each season will not afford a better opportunity to

the bivalves to spat and develop into pearl-bearers.

The last great fishing took place during the month of March in 1877;

and, as the results are said to have exceeded those of any previous

season for many years past, a short account of the manner in which

the operations were carried out, together with a review of the system

adopted for protecting the beds from exhaustion, may be interesting.

In the first place, it will be well to remove a misapprehension which

exists as to the identity of the so-called pearl-‘oyster.’ This mollusc

is not an oyster properly so called, but a species of mussel, and is

easily distinguished from an oyster by the squareness and length of the

shells at the ‘hinge.’ Like the common mussel of our own shores, it

attaches itself to stones and rocks by means of certain fine but strong

cords or _byssus_, which it spins at will; and not, like the oyster, by

a secretion of shell-matter. These cords are very tough when the animal

is young, but decrease in strength as it increases in age, till at last

they rot away altogether, leaving the creature at the mercy of tides

and storms.

While the pearl-oyster is still young, and before it has finally

attached itself to a suitable rock, it often breaks away from its

anchorage; so that it not unfrequently happens that a pearl-bank well

filled with oysters suddenly disappears altogether. Some authorities

assert that the pearl-oyster has the faculty of casting its byssus

and voluntarily migrating; but whether this is the fact or not, it

is certain that the above circumstances demand the serious attention

of the authorities, and have led to the adoption of a system of

half-yearly inspection of the banks, in order to determine two

important points, namely whether the young brood has forsaken its

birthplace, or the full-grown oysters are, through old age, breaking

away and being destroyed.

The duration of the life of the oyster is another necessary point to

determine; and various suggestions have been made, with the double

object of ascertaining the age of an oyster without the necessity of

continually watching its growth, and of shewing when a bed is fit to be

fished. The weight of the mollusc affords some clue to the elucidation

of this problem, but there is an obstacle to the adoption of this

method in the difficulty of accurately weighing a number of specimens

in an open boat at sea, even if the scales and weights should be at

hand. One of the government officials, however, has suggested a method

of ascertaining the age of the mollusc by the weight of the shells,

cleaned and dried with the animal removed. This can be done at any

time; and a series of experiments conducted by him gives the following

results. The shells of an oyster one year old, with the body of the

animal removed, weigh four drachms; those of an oyster two years old

weigh twelve drachms; three years old, nineteen drachms; and four years

old, twenty-five drachms. This scale of weights will apply of course

only to pearl-oysters from the Ceylon banks; as a difference in the

food, in the composition of the water and soil, and the temperature in

other parts of the world, would no doubt affect the rate of growth

and the deposit of the calcareous matter forming the shell. Empty

shells have been found weighing as much as forty drachms, thus giving a

probable age of about eight years.

The question arises, What _are_ pearls? Are they a morbid concretion

of matter produced in the endeavour to heal a wound or to cover some

irritating body that cannot easily be ejected from the shells? Are

they the result of a disease, or are they simply an over-production of

the matter forming the shell of the creature? Whatever they are, it is

only in the adult oyster that they are found of any size. The rate of

growth in the size of a pearl cannot of course be actually ascertained;

but by a series of averages, taken from the produce of a large number

of oysters from the same bed in different years, it is proved that

after the fourth year, the yield of pearls both in quantity and quality

rapidly increases. It is in the hope of a bed of oysters which produces

say five hundred rupees’ (L.50) worth of pearls per thousand oysters

one year, so improving as to yield double that value next year, that

many a fine bank has been left to perish from the causes referred to

above, as well as from the attacks of enemies or sickness.

The whelk has lately been discovered to be a serious enemy to the

pearl-oyster, just as it to the edible oyster of commerce; and a

curious disease occasionally manifests itself among the inhabitants

of the banks. The fatty portion of the animal, under which pearls are

usually found, and which is usually of a pale cream colour, assumes a

yellow tint, denoting sickness of some sort, the exact nature of which

has not yet been ascertained.

Pearl-fishing is at the best only a gigantic lottery, the prizes in

which bear a very small proportion to the blanks. But in this as in

many other uncertain pursuits, hope always tells a flattering tale, and

keeps awake the energies of thousands of interested operators. First

there are the divers, who perform the actual operations of fishing

for pearls. Arrayed in Nature’s garb, and provided with a knife and a

small bag of netting in which to collect the gathered oysters, and with

a rope tied round their waists, and a heavy stone attached to their

feet, they are let down into the water, taking first a deep breath, and

remaining there till forced to rise again. Expert divers will remain

beneath the water for sixty, ninety, and even a hundred and eighty

seconds. This period they occupy in detaching the mussels from the

rocks, a matter frequently of much difficulty. Those of very small size

they do not attempt to gather, for, as we have shewn, the larger the

shells the more chance of their containing a pearl. The native divers

are able to guess at the age of the oyster by the resistance it offers;

and, as explained above, the older the oyster the more easily it is

detached, and the greater the chance of its producing a large pearl.

On banks not over thickly populated, there is barely time to gather

half-a-dozen oysters at a dive—a dozen is an extra good haul; in more

favourable circumstances from fifty to one hundred may be collected by

one man. The diver then detaches the stone from his feet, gives a tug

at the rope, and is rapidly hauled up; the stone, attached to another

line, being afterwards pulled up for use again. His gleanings are then

placed on board the boat; and from it he descends again on another

venture. It may be imagined that life among men who so overstrain their

natural functions is very precarious; for though they are brought up to

the practice from their boyhood, a diver seldom lives to see old age or

even maturity.

The weather is an important factor in the calculation of the

pearl-fisher. ‘Pearl-fishing weather’ is a proverb in Ceylon, and has

much the same relation to the meteorological conditions of that island

as ‘harvesting weather’ bears to our own climate. A light steady breeze

from the north-east is the most favourable for fishing the _paars_ on

the south and west coasts of Ceylon, as the sea is sheltered by the

island, enabling the boats to sail and manœuvre easily. Sometimes the

wind will suddenly shift, and a squall will drive the boats home with

no little danger to the crews; or a heavy thunder-storm, such as only

the tropics can produce, will fall like a bomb-shell upon the scene

of the industry; and the wonder is that the frail habitations fitted

up for the accommodation of the fishers and others are not literally

washed away.

Besides the actual divers, there are the working crews of the boats,

the men employed in ‘washing’ the oysters on shore, the carrying boats,

the provision-merchants, purveyors of arrack and other liquors, bazaar

owners, the petty _chetties_ or traders in pearls, the large merchants

who buy thousands of oysters with a nod of the head, the police—and

they form no small proportion of the whole population—and other

government officials.

The boats are manned with a crew of one or two men, and frequently

a ‘counter’ to take reckoning of all the oysters brought up. The

boats are usually worked over the ground in circles, being ranged in

line some yards apart, and each taking a small circle and advancing

gradually over a certain assigned area. Sometimes they are placed close

together and advance in line across the bed. But before the boats

are permitted to start, the beds, having been examined by government

officials, are buoyed off, and no boat is allowed to go beyond the

limits thus defined. When the number of boats entered is very large—and

sometimes as many as five or six hundred collect together for the

prosecution of the industry—they are placed in separate divisions of

eighty to a hundred each, and lots are cast for the order in which

the divisions shall proceed, each division taking a day or a tide in

rotation.

For the accommodation of the large numbers of people brought

temporarily together by the fishery, large villages, the houses

of which are composed of bamboo, wood, furze, mud, and any light

material, suddenly spring up along the seashore, the population being

further increased by the arrival of the buyers and merchants. From

China, Japan, and all parts of the East, connoisseurs in pearls and

pearl-oysters are attracted to the scene of operation, and the activity

and excitement are often intense. A sample of five or six thousand

oysters is examined by the government, and from the results of this

sample the sales proceed. The government take three-fourths of every

boat-load brought in, and special officials are appointed to dispose

of these shares as soon as possible and at the best possible price.

A daily auction takes place, and the lots are knocked down to the

highest bidder. The method of valuing is so much per thousand oysters,

the prices ranging from forty rupees (L.4) to one hundred and twenty

rupees (L.12) per thousand.

The fishermen, who sell their own share on their own account, generally

receive higher prices than those fetched by the government sales; for

the small traders, buying by the dozen, naturally pay more dearly

than if they bought several thousands at a time; besides, the fishers

can afford to wait longer till a good offer occurs. Sometimes the

_chetties_ will buy a dozen at a time and open them, repeating their

purchases dozen after dozen, in the hope of finding a good gem, which

they either sell on the spot or take away with them into the interior.

The occurrence of a good pearl always sends prices up; and a man may

sell an unusually fine specimen for seven or eight hundred rupees, and

see it change hands for twice and three times the amount.

The collection of so many thousand natives, with very rudimentary

ideas of the laws of health and cleanliness, and with facilities for

drinking arrack and other ardent liquors which are as regularly to be

met with on the shores of Ceylon as they are in the crowded fairs and

race-courses of our own country, is often the cause of an outbreak of

cholera, smallpox, or other zymotic disease. The greatest precautions

are, however, taken to prevent such a catastrophe, and all cases of

illness are at once isolated.

The operation of opening the pearl-oysters is also conducive to

disease. To open each oyster when fresh would be a work of infinite

labour; they are therefore packed together in large vessels called

_ballams_, where, under the tropical heat, the animals soon die and

putrefy, and the shells, gaping open, are easily washed and examined.

The greatest watchfulness has to be exercised over the natives employed

in this work, where the owners do not perform the operation themselves.

A pearl is very easily secreted either in the folds of the scanty

dress, or in the mouth or ears, or even swallowed; and the Singhalese

and indeed all the natives of the East are adepts in the art of

thieving. To cheat the government out of their shares of the spoil, it

is no unusual thing for the boatmen to throw large packages of oysters

overboard, buoying them, so that they may be recovered under cover of

darkness or on the last day of fishing, which is usually devoted to a

general _sanjayan_ or scramble. All boats, whether belonging to the

authorised divisions or not, are then allowed to go out and keep what

they can get.

These divers render essential service in discovering and reporting the

existence of unrecorded rocks and shoals; and many a permanent record

of their operations is left in the shape of a warning buoy, stationed

to warn the navigator of a treacherous reef.

When, from the diminished daily results of the fishing, a sign is given

that the bed is being exhausted, the order is given to stop fishing.

The _sanjayan_ over, the bed is deserted, save by the government

launch appointed to remove the buoys which marked off the limits of

the ground; the boats gradually make off as wind and weather permit,

for their respective ports; the merchants pack up their purchases and

take their departure for the great towns and cities; the government

officials, having completed the records of the fishery, are gradually

recalled; the temporary huts are burnt to the ground; and the place

assumes its normal state of peaceful repose, disturbed only, or rather

intensified, by the presence of some wandering native bird, or by the

occasional visit of a roaming elephant or jackal.
