The mode of killing whales in the Mozambique Channel, and by the Africans all along their south-east coast, is extremely simple; it shews how much may be effected by perseverance; and affords, indeed, an admirable moral, together with no insignificant satire upon the great expence to which Europeans, engaged in that pursuit, put themselves, without becoming more certain of success.
When a whale is seen within a moderate distance of the shore, basking, as they often do for hours together, with little intermission, during the heat of the day, the fishermen put off in their canoes, which are excavated from large trees, and equipped with out-riggers on each side. Generally, each canoe carries from four to six persons; but those which are intended to approach the whale, give over their crew, with the exception of one spearsman, and one paddler, to the other canoes.
The paddler urges his canoe very gently, until within about eight or ten yards of the whale; sidling up with extreme caution so as to be parallel with its shoulders; this is done to avoid that lash of the tail which the fish invariably gives, as he plunges downwards, on feeling the spear enter his flesh. The weapons used on this occasion are about five feet long, extremely elastic, and loaded at each end with iron or lead; whereby not only the impetus is encreased, but the vibration, occasioned by the opposite weights, causes the point, which is of iron, very acute and barbed, to wriggle deeper into the flesh. Previous to striking, the head of the canoe is turned towards the whale, and a slight retrocessive motion is given; so that, at the very moment when the spear is delivered, the paddler may, by a sudden exertion, pull further away, and avoid the danger. It sometimes happens, that the spearsman is thrown from his station into the water, by the sudden motion of the boat opposed to his own action; being invariably expert swimmers, such an accident is not in the least regarded. After sinking to a great depth, the whale rises again to the surface, perhaps a mile off, where other boats are waiting to repeat the attack; by a succession of which he is, ordinarily in the space of an hour, so completely worn out, as to float without the power of resistance, when a long spear, pushed through between his ribs, speedily terminates the struggle.
The whale being dead, all the canoes join their efforts to tow the carcase towards the shore; where, upon some sandy part, a division is made of the spoil; each of the crews cutting away with hatchets and cutlasses, as much of the blubber as they can expend. The residue is sold, or exchanged for other articles of consumption, dress, &c. to the inhabitants of the neighbouring towns: the whale-bone is reserved for sale to European traders; the ribs serve for the couples of houses, or rather cabins; and the joints of the vertebræ, after being neatly trimmed at the sides, and at one end, make very comfortable stools; of which, however, the strong, rank scent, retained for many months, would prove highly offensive to any but persons who consider the blubber, after the oil has been fried, and pressed out, to be a delicate morceau!
The operation of cutting away the adipose parts; which come off in immense lumps, of from eight inches to a foot, or fifteen inches in depth, is rather laborious; it is likewise attended with the danger of attacks from an immense number of sharks, that instinctively follow the carcase; and, so soon as it is hewn open, seize whatever falls from it with the most ferocious avidity. Hence, the fishermen are obliged to be extremely careful not to expose their limbs, by allowing them to dangle in the water: such of the crews as fall overboard, are usually snapped up by their greedy competitors; which, it is said, are known in these parts to grow to the enormous length of thirty feet!
It has often occurred to me, that, in lieu of casting loose the remains of whales, after cutting away the blubber, as our fishermen usually do, an immense quantity of ammonia might be extracted, were the skeletons to be towed to the shore, and there to be applied to that purpose. Fuel is rarely wanting, and there being invariably sufficient crews on board our whale-ships, which cannot be always employed, it should seem that much advantage might thus arise, with little or no expence: the price of ammonia is very high, but if it could be lowered, immense quantities would be consumed. It is to be remarked, that this valuable alkali has not hitherto been put under that course of experiments to which it certainly would be subjected, did the price not stand in the way of its use on a large scale: the following qualities, as stated in the invaluable Dispensary given to the public by Dr. Andrew Duncan, may plead in apology for my digressing so far on a subject, not apparently connected with my prospectus; but which, considered philosophically, is, by no means, irrelevant thereto.
Dr. Duncan states, that, ‘ammonia does not dissolve animal substances; it extinguishes flame; colors vegetable-blues green; is decomposed by being transmitted through a red hot tube, and, by the electric spark, into its constituent gases, and by oxygen, and atmosphoric air at a red heat; by oxy-muriatic acid, it is converted into water and hydrogen-gas. It is absorbed, without change, by porous bodies; it dissolves sulphur and phosphorus; and combines readily with water, in all its states. Ammonia combines with the acids, forming neutral salts. It is formed during the putrefactive fermentation; and is commonly classed among the alkalies.’ My readers will see, at once, how wide a field is open for speculation!
After quitting Johanna, which is the only island, in that cluster, whither European vessels ever intentionally resort, such as may be bound to Bombay usually make the great peninsula somewhere about Anjengo, pursuing their course up the western, or Malabar side; while those proceeding to Coast and Bay, (i.e. Madras and Bengal,) endeavor to get a sight of Dondra-Head, which determines both their latitude, and their longitude; thence they pass round the eastern side of the island of Ceylon, of which the shore is sufficiently bold to allow their keeping within two or three miles of the land with perfect safety, in regard to reefs or shoals; but this quarter being extremely subject to violent gales, that come on rather suddenly, or, at least, without much notice, and are known by the name of ‘white squalls,’ it is generally considered most prudent to keep a good offing. These white squalls invariably take place when the sky is free from clouds; but may sometimes be distinguished, as they approach, by the white spray raised from the water by the violence of the wind: so soon as that is discovered, all the small sails should be taken in, and the ship rendered as compact above as time may admit. The warning spray is too frequently unnoticed; and, even when perceived, is, for the most part, too close at hand to admit of much preparation. This insidious danger extends, more or less, from the south end of Madagascar up to the latitude of Tranquebar, being most prevalent to the southward of the Line, where the south-west trade wind prevails at all times.
The island of Ceylon has been adopted as a royal possession, in the government of which the Company have no share whatever. The whole of the civil establishment are appointed by the king; and the military receive their commissions from the secretary at war, independent of the Company’s chartered establishment. It generally happens, however, that some of the Madras battalions are on duty in the island; which has always been in a most perturbed state, especially since it came under our dominion. It is rather unusual for the Company’s ships to touch here, except when sent to Columbo with stores, or calling there on their way home for cargoes and passengers. None but very small vessels can pass between Ceylon and the Main, notwithstanding the great width of the channel, on account of that immense reef, intermixed with shoals, stretching across its northern part. This reef, called ‘Adam’s Bridge,’ is supposed to be formed by the summits of mountains, that, by some dreadful convulsion, were sunk below those waters, between which they originally formed a stupendous isthmus, like that of Darien, connecting Ceylon with the continent.
Notwithstanding what has been said by many authors on the subject of ‘spicy gales,’ the expectation of meeting with perfumed breezes in this quarter should not be too much encouraged. After coasting the whole length, from Dondra-Head to Point Pedro, not one puff, conveying the idea of proximate ambrosia, ever reached my nose. It must, at the same time, be understood, that a certain terraceous scent, something like that resulting from rain in dusty weather, generally prevails within a certain distance of a windward shore; particularly where the country is well wooded.
