CHAPTER IV
GEOGRAPHY – CLIMATE, ETC
ОглавлениеThe generally accepted theory as to the formation of the Philippines is, that they all formed part of a vast primitive continent, which was broken up by some great convulsion of nature, and that these islands are the scattered fragments of that continent. Buzeta supposes that from Luzon the other islands were detached.8
The Indians have a tradition that the earth was borne on the shoulders of a giant, who, getting tired of his heavy burden, tumbled it into the ocean, leaving nothing above the waters but the mountains, which became islands for the salvation of the human race.
I do not propose to give a detailed geographical description of the Philippine Islands. Buzeta’s two octavo volumes will furnish the most accurate particulars with which I am acquainted as to the various localities. The facts which I collected in the course of my personal observation refer specially to the islands of Luzon, Panay, and Mindanao. The more general information has been derived from Spanish authorities on the spot, or has been found in Spanish books which I have consulted. I cannot presume to consider the present volume as complete or exhaustive, but it will contribute something to augment that knowledge which is already possessed.
The extent of the Philippine Archipelago is about 300 leagues from north to south, and 180 leagues from east to west. The islands of which it is composed are innumerable, most of the larger ones having some Spanish or mestizo population. A range of irregular mountains runs through the centre of the whole. Those known by the name of the Caraballos, in Luzon, are occupied by unsubdued races of idolatrous Indians, and extend for nearly sixty leagues. Several large rivers have their sources in the Caraballos. At the top of Mount Cabunian, whose ascent is very difficult, there is a tomb worshipped by the pagan Igorrotes. There are large lakes in several of the islands, and during the rainy season some of them become enormously extended. These inundations are naturally favourable to the vegetable productions by fertilizing vast tracts of land. Mindanao, which means “Men of the lake,” has its Indian name from the abundance of its inward waters, in the same way that La Laguna has been adopted by the Spaniards as the designation of the province bordering on the Lake of Bay. In this latter district are many mineral and thermal springs, which have given to one of its pueblos the name of Los Baños (the baths). One of them issues from the source at a temperature of 67° of Reaumur. They are much visited by the inhabitants of Manila. There are boiling springs in the pueblo of Mainit.
The climate of the Philippines is little distinguished from that which characterizes many other tropical regions of the East. It is described in a Spanish proverb as —
Seis meses de polvo,
Seis meses de lodo,
Seis meses de todo.
“Six months of dust, six months of mud, six months of everything;” – though it may generally be stated that the rainy season lasts one half, and the dry season the other half of the year. There are, however, as the distich says, many months of uncertainty, in which humidity invades the ordinary time of drought, and drought that of humidity. But from June to November the country is inundated, the roads are for the most part impassable, and travelling in the interior is difficult and disagreeable. Even in the month of December, in several districts of Luzon, we found, as before mentioned, places in which carriages are necessarily abandoned, the palanquin bearers being up to their thighs in mud; and other places in which we were compelled to open a new way through the woods. The heat is too oppressive to allow much active exertion in the middle of the day, and the siesta is generally resorted to from 1 to 3 o’clock P.M., before and after which time visits are paid and business transacted. The pleasant evening time is, however, that of social enjoyment, and the principal people have their tertulias, to which guests are welcomed from half-past 8 o’clock to about 11 o’clock P.M.
The variations of the thermometer rarely exceed 10° of Reaumur, the maximum heat being from 28° to 29°, the minimum 18° to 19°. Winter garments are scarcely ever required.
The difference between the longest and shortest day is 1h. 47m. 12s. On the 20th June, in Manila, the sun rises at 5h. 33m. 12s., and sets at 6h. 26m. 48s.; on the 20th December, it rises at 6h. 26m. 48s., and sets at 5h. 33m. 12s.
The minimum fall of rain in Manila is 84 inches, the maximum 114. Hailstorms are rare. There is no mountain sufficiently high to be “snow-capped;” the highest, Banaho, is between 6,000 and 7,000 feet above the level of the sea.
Like other tropical climates, the Philippines are visited by the usual calamities gathered by the wild elements round that line which is deemed the girdle of the world. Violent hurricanes produce fearful devastations; typhoons cover the coasts with wrecks; inundations of rivers and excessive rains destroy the earth’s produce, while long-continued droughts are equally fatal to the labours and the hopes of husbandry. Earthquakes shake the land, overturn the strongest edifices and sport destructively with the power of man; volcanic mountains inundate the earth with their torrents of burning lava. Clouds of locusts sometimes devour all that is green upon the surface of the ground; and epidemic diseases carry away multitudes of the human race. The ravages caused by accidental fires are often most calamitous, as the greater part of the houses are constructed of inflammable materials. When such a disaster occurs, it spreads with wonderful rapidity, and, there being no adequate means of extinction, a whole population is often rendered houseless.
During the change of the monsoons especially, the storms are often terrific, accompanied by very violent rains, fierce lightning and loud thunder. If in the night, the darkness thickens. Many lose their lives by lightning strokes, and houses are frequently carried away by the vehemence of the torrents.
Bagyo is the Indian name for hurricane. These violent outbreaks are generally announced in the morning by a light smoky mist which appears on the mountains; it gathers, and darkens, and thickens into heavy clouds, and before day closes breaks out with its fearful and destroying violence, raging from an hour and a half to two hours. M. de Gentil says that in the torrid zone the clouds which bring the most destructive tornadoes are at an elevation not exceeding 400 toises of perpendicular height.
The largest of the volcanoes is that of Mayon in Luzon. It is in the shape of a sugar-loaf, perfectly conical. Its base covers several leagues in the provinces of Albay and Camarines, and it is one of the most prominent objects and landmarks visible from the sea; there is a constant smoke, sometimes accompanied by flames; its subterranean sounds are often heard at a distance of many leagues. The country in the neighbourhood is covered with sand and stone, which on different occasions have been vomited forth from the crater. There is a description by the Alcalde of an eruption in 1767, which lasted ten days, during which a cone of flame, whose base was about forty feet in diameter, ascended, and a river of lava was poured out for two months, 120 feet in breadth. Great ruin was caused to the adjacent villages. The lava torrent was followed about a month afterwards by enormous outpourings of water, which either greatly widened the beds of the existing rivers, or formed new channels in their rush towards the sea. The town of Malinao was wholly destroyed, and a third part of that of Casana. Many other villages suffered; forests were buried in sand; which also overwhelmed houses and human beings. The ravages extended over a space of six leagues.
From an eruption at Buhayan, sixty leagues from Zamboanga, in the island of Mindanao, in 1640, large masses of stone were flung to a distance of two leagues. The ashes fell in the Moluccas and in Borneo. Dense darkness covered Zamboanga. Ships at sea lighted their lamps at 8 A.M., but the light could not be seen through the clouds of sand. The mountain whence the explosion originated disappeared, and a lake was formed and still remains in the locality as a record of the agitation. The waters of the lake were long white with ashes. The noise of the eruption was heard in Manila.
About twenty leagues from Manila is the province of Batanga. In one of the bays is an island called by the natives Binintiang Malagui, remarkable for its beauty, for the variety of its vegetation, and the number of animals which inhabit it. The eastern part of the island is a mountain, whose extinct volcano is seen in the form of a truncated cone of enormous extent, surrounded by desolation. The flanks of the mountain have been torn by vast channels, down which the lava-streams must have flowed. The sides are covered with ferruginous and sulphurous pyrites and scoriæ, which make the ascent difficult. It is most accessible on the southern side, by which we reach the mouth of the crater, whose circumference exceeds three miles, and whose deep and wild recesses exhibit astounding evidences of the throes and agitations which in former times must have shaken and convulsed this portion of the earth. A Spanish writer says it looked “like an execrable blasphemy launched by Satan against God.” There are still some signs of its past history in the smoke which rises from the abyss; but what characterizes the spot is the contrast between the gigantic wrecks and ruins of nature on one side, and the extreme loveliness and rich variety of other parts of the landscape. Descending into the crater by the help of cords round the body, a grand platform is reached at the depth of about 600 feet, in which are four smaller craters, one constantly and the others occasionally emitting a white smoke, but they cannot be approached on account of the softness and heat of the soil. To the east is a lake from which a stream runs round the craters over beds of sulphur, which assume the colour of emeralds. Formerly this lake was in a state of boiling ebullition, but is now scarcely above the natural temperature; it blackens silver immediately. Frequent earthquakes change the character of the crater and its neighbourhood, and every new detailed description differs from that which preceded it. The Indians have magnificent notions of the mineral riches buried in the bosom of the mountain, the sulphur mines of which were advantageously worked a few years ago, when a well-known naturalist (Lopez, now dead) offered to the Spanish government large sums for the monopoly of the right of mining the district of Taal.
On the 21st of September, 1716, sounds like those of heavy artillery proceeded from the Taal volcano, and the mountain seemed to be in a state of ignition over a space of three leagues towards Macolot. Gigantic towers of boiling water and ashes were thrown up, the earth shook on all sides, the waters of the lake were agitated and overran its banks: this lasted for three days. The water was blackened, and its sulphurous smell infested the whole district. In 1754 a yet more violent eruption, lasting eight days, took place, with terrible explosions, heavings of the earth, darkness, and such clouds of dust and ashes that all the roofs of the houses at Manila, at a distance of twenty leagues, were covered. Great masses of stones, fire and smoke were thrown from the mountain. The lake boiled in bubbles. Streams of bitumen and sulphur ran over the district of Bong-bong. The alligators, sharks, tunnies, and all the large fish, were destroyed in the river and flung upon the banks, impregnating the air with stench. It is said that subterranean and atmospheric thunders were heard at a distance of 300 leagues from the volcano, and that the winds carried the ashes to incredible distances. In Panay there was midday darkness. Many pueblos were wholly destroyed; among them Sala, Janavan, Lipa, and Taal: others bearing the same names have been since founded at a greater distance from the mountain.
Lopez gives a description of his descent into the crater. He employed 100 men for eight days to make a slope for his going down. He says the crater is oval, two miles in diameter; that the lake within the crater is surrounded by level and solid ground; that there was a deep chasm which had been recently ignited: there was sulphur enough to load many ships. He saw a cube of porphyry 20 to 25 feet square. The crater wall is perpendicular on all sides; that on the north 1,200 feet high, the lowest exceeding 900 feet. He says he believes the south sides to be of porphyry. At night, midway of the descent, he saw “thousands of millions” of jets, whose gas immediately inflamed on coming in contact with the atmosphere, and he heard many small detonations. The waters of the lake were impregnated with sulphuric acid, and 12 lbs. of the water, when distilled, left a mineral residuum weighing 2½ lbs.
There are many remarkable caves in the Philippines. I translate a description of one in the province of Tondo. Two stony mountains unite, and on their skirt is the road towards a branch of the main river. On the left is a cave whose entrance fronts the south. The mouth is almost covered with tangling vegetation, but it is arched, and, being all of marble, is, particularly in the sunshine, strikingly beautiful. You enter by a high, smooth, natural wall like the façade of a church, over which is a cavity roofed as a chapel. The interior pathway is flat, about four yards in breadth and six in height, though in some places it is much loftier. The roof presents a multitude of graceful figures, resembling pendent pineapples, which are formed by the constant filtration and petrifaction of the water. Some are nearly two yards in length, and seem sculptured into regular grooves; others are in the shape of pyramids whose bases are against the roof. Arches, which may be passed both from above and below, are among these wonderful works. Not far from the door is a natural staircase, mounting which you enter a large chamber, on whose right hand is another road, which, being followed, conducts to a second staircase, which opens on the principal communication. Suspended on one wing are immense numbers of bats, who occupy the recesses of the ceiling. Though there is mud in some of the paths, the ground is generally of stone, which, on being struck, gives a hollow sound as if there were passages below. Penetrating the cave for above 200 yards, a loud noise is perceived coming from a clear bright river, by the side of which the cave is continued under a semicircular roof. The great cave has many smaller vaults and projections of a grotesque and Gothic character. The course of the stream is from the north-west to the south-east.
The destructive ravages and changes produced by earthquakes are nowhere more remarkable than in the Philippines. They have overturned mountains, they have filled up valleys, they have desolated extensive plains; they have opened passages for the sea into the interior, and from the lakes into the sea There are many traditional stories of these territorial revolutions, but of late disasters the records are trustworthy. That of 1796 was sadly calamitous. In 1824 many churches in Manila were destroyed, together with the principal bridge, the barracks, great numbers of private houses; and a chasm opened of nearly four miles in length. The inhabitants all fled into the fields, and the six vessels in the port were wrecked. The number of victims was never ascertained. In 1828, during another earthquake, the vibration of the lamps was found to describe an arch of four and a half feet; the huge corner-stones of the principal gate of the city were displaced; the great bells were set ringing. It lasted between two and three minutes, rent the walls of several churches and other buildings, but was not accompanied by subterranean noises, as is usually the case.
There are too few occasions on which scientific observations have been made on the subject of earthquakes, which take men by surprise and ordinarily create so much alarm as to prevent accurate and authentic details. A gentleman who had established various pendulums in Manila for the purpose of measuring the inclination of the angles and the course of the agitation, states that, in the slight earthquakes of 20th and 23rd June, 1857, the thermometer being at 88°, the direction of the first shock was from N.N.E. to S.S.E., the duration 14 seconds, and the oscillation of the pendulum 1½ degrees; time, 2h. 0m. 40s. P.M.: 20th June. Second shock from N.E. to S.W.; duration, 26 seconds; oscillation of pendulum, 2 degrees; time, 2h. 47m. P.M.: 20th June. Third shock S.W. to N.; duration of the shock, 15 seconds; greatest oscillation, 6 degrees, but slight movements continued for a minute, and the oscillations were observed from 2 degrees to three-quarters of a degree; time, 5 P.M.: 23rd June.
Earthquakes have produced great changes in the geography of the Philippines. In that of 1627, one of the most elevated of the mountains of Cagayan disappeared. In 1675, in the island of Mindanao, a passage was opened to the sea, and a vast plain was emerged. Successive earthquakes have brought upon Luzon a series of calamities.
Endemic diseases are rare in the Philippines. Intermittent fevers and chronic dysentery are among the most dangerous disorders. There have been two invasions of cholera, in 1820 and 1842. Elephantiasis, leprosy, and St. Anthony’s fire are the scourges of the Indians; and the wilder races of the interior suffer from a variety of cutaneous complaints. The biri biri is common and fatal. Venereal diseases are widely spread, but easily cured. Among the Indians, vegetables alone are used as medicaments. Chinese quack-doctors have much influence. In the removal of some of the tropical pests, no European can compete with the natives. They cure the itch with great dexterity, and are said to have remedies for pulmonary phthisis. Their plasters are very efficacious in external applications. They never employ the lancet or the leech. Surgical science is, of course, unknown.
There have been generally in the Philippines a few successful medical practitioners from Europe. Foreigners are allowed to exercise their profession, having previously obtained the authority of the Spanish Government; but the natives seldom look beyond their own simple mode of dealing with the common diseases of the islands; and in those parts where there is little or no Spanish population, no one is to be found to whom a surgical operation could safely be intrusted. The vegetable world furnishes a great variety of medicinal herbs, which the instinct or the experience of the Indian has turned to account, and which are, probably, on the whole, as efficacious as the more potent mineral remedies employed by European science. Quinine, opium, mercury, and arsenic, are the wonder-workers in the field of Oriental disease, and their early and proper application generally arrests the progress of malady.
I found practising in the island of Panay Dr. Lefevre, whom I had known in Egypt more than twenty years before, and who was one of the courageous men who boldly grappled with the current superstitions respecting the contagious character of the Oriental plague, and the delusions as to the efficacy of quarantine regulations, so really useless, costly, and vexatious. He placed in my hand some observations which he had published at Bombay in 1840, where vessels from the Red Sea were subjected to sanatory visitations. He asserts that plague is only generated at particular seasons, in certain definable conditions of the atmosphere, and when miasma is created by the decomposition of decaying matter; that endemic plague is unknown in countries where proper attention is paid to hygienic precautions; that severe cold or intense heat equally arrests the progress of the plague; that the epoch of its ravages is always one when damp and exposed animal and vegetable substances emit the greatest amount of noxious gases; and that plague has never been known to originate or to spread where the air is in a state of purity. I was glad to rediscuss the matter with him after so long an added experience, and to find he had been more and more confirmed in his former conclusions by prolonged residence in the tropics, where endemic and epidemic diseases partake of the pestilential character, though they do not assume the forms, of the Levant plague. Dr. Lefevre affirms that quarantines have done nothing whatever to lessen the dangers or check the ravages of the plague, but much to encourage its propagation. He complains of the deafness and incredulity of those whom the examination of a “thousand indisputable facts” will not convince, and he thus concludes: – “If I had not with peculiar attention studied the plague in the midst of an epidemic, and without any more precautions than if the danger was nothing – if, subsequent to the terrible visitation of 1835 in Egypt, I had not been frequently a witness to the scourge – if, finally, since that epoch I had not given myself up, with all the warmth of passion, to the constant study of this malady, to the perusal of histories of the plagues which have ravaged the world, and to the examination of all sorts of objections – I should not have dared to emit such a decided opinion – an opinion respecting the soundness of which I do not entertain the slightest doubt.”
One cannot but be struck, in reference to the geographical character of these islands, with the awful serenity and magnificent beauty of their primeval forests, so seldom penetrated, and in their recesses hitherto inaccessible to the foot of man. There is nothing to disturb their silence but the hum of insects, the song of birds, the noises of wild animals, the rustling of the leaves, or the fall of decayed branches. It seems as if vegetation revelled in undisturbed and uncontrolled luxuriance. Creeping plants wander from tree to tree; lovely orchids hang themselves from trunks and boughs. One asks, why is so much sweetness, so much glory, wasted? But is it wasted? To the Creator the contemplation of his works, even where unmarked by human eye, must be complacent; and these half-concealed, half-developed treasures, are but reserved storehouses for man to explore; they will furnish supplies to awaken the curiosity and gratify the inquiry of successive ages. Rove where he may – explore as he will – tax his intellect with research, his imagination with inventions – there is, there will be, an infinite field around and above him, inexhaustible through countless generations.
