The island and province of Mindoro lies in the strait of its name and south of Luzon. It has in the center an elevated plain, we quote from the military notes issued by the War Department, from which many sierras extend in different directions to the coast, making the latter rugged and dangerous. The island is of an oval form, with a prolongation of the northern portion toward the west. Though an easy day's sail from Manila, it is one of the least populous islands of the archipelago, being extremely mountainous, covered with dense forests, and in the more level parts near the coast full of marshes, and very unhealthful. The inhabitants of the coast are Tagals, but in the interior there is a low tribe of the Malayan race, probably the indigenes of the island, and called Manguianos, speaking a peculiar language and living in a very miserable manner on the products of a rude agriculture. There are also said to be some Negritos, but of these very little is known. There are many short streams. The island is 110 miles long and has an area of 3,087 square miles. The population is 106,170. There is little known of the mountains of the interior, as the inhabitants dwell mainly on the coasts. Mindoro constitutes one of the provinces of the Philippines under an alcalde.
The capital is Calapan, with a population of 5,585. It is situated to the north, on the harbor of its name, defended by a fort of regular construction; it has about 500 houses, among the notable stone ones being the parish, court house and jail, and casa real. It is the residence of the alcalde mayor and several public functionaries. The city is situated 96 miles from Manila.
Mount Kalavite is a long-backed promontory, the western slope of which forms Cape Kalavite, and the northern slope Point del Monte; the summit, about 2,000 feet high, appears dome-shaped when seen from the west, but from the north or south it shows a long ridge fairly level; the western end of this ridge is the highest part.
The capital of the province, Calapan, is a coast town. The inhabitants are occupied in hunting, fishing, and ordinary weaving. The commerce is insignificant. Sand banks extend in front of the town to a distance of one-half mile. To clear these, the northern Silonai islet should not be shut out by Point Calapan. On this line, near the north edge of the banks, the soundings are 36 to 46 fathoms.
The Semirara Islands form a group of eight islands, all surrounded by reefs.
Semirara, the largest of the group, is hilly, about 512 feet high at the highest part. The west coast includes several little bays almost entirely obstructed by reefs, on the edge of which are depths of 4 3/4 to 13 fathoms; and off the town of Semirara, which stands on the top of the hill facing the largest bay, the anchorage is very bad, even for coasters. The east coast is bordered by a reef, which extends about a mile from the northeast part of the island; on coming from the north this coast of the island must not be approached within three miles until the town of Semirara bears full west. There is anchorage at the south of the island in 5 to 8 fathoms, sand, during the northeast monsoon. Good coal for steaming purposes was found on the island by Captain Villavicencio, of the Spanish navy.
Tablas Island is, mountainous, and on its northern extremity is the peak Cabezo de Tablas, 2,405 feet high; generally the coasts are clear and steep-to. Off the north end are two rocky islets, distant one cable from the coast; the larger one is clear and steep, the smaller one has rocks around it.
The west coast of Mindoro Island has no soundings off it excepting in the bays, or within one or two miles of the shore in some places. In the interior double and treble chains of mountains extend through the island, and some low points of land project from them into the sea.
Paluan Bay affords excellent shelter in the northeast monsoon, and is also a convenient place for vessels to obtain supplies when passing through Mindoro Strait. The bay is five miles wide at the entrance, of a semi-circular form, running back three miles in a northerly direction. There are no dangers in it.
A small river disembogues where good water can be obtained with facility; and on the beach there is plenty of driftwood. The coral projects one-half mile from the entrance of the river, and has 10 and 12 fathoms close to its edge.
Care must be taken when working into Paluan Bay, for the squalls come violently off the high land, and very sudden, and at night do not give the least warning.
The Calamianes are a group of high islands lying between the northeast end of Palawan and Mindoro, and extending between the parallels of 11 degrees 39 minutes and 12 degrees 20 minutes N., and the meridians of 119 degrees 47 minutes and 120 degrees 23 minutes E. Busuanga, the largest island of the group, is about 34 miles in extent NW. by W. and SE. by E., and 18 miles broad. It is very irregular in form, being indented with numerous deep bays. The islands and reefs which front its northeast side form the western side of Northumberland Strait.
These islands form, with the northern part of Palawan and the Cuyos Islands, a province, the capital of which is at Port Tai Tai. The climate of these islands is in general hot and unhealthful. Intermittent fevers and cutaneous diseases prevail, attributable, in all probability, to the great moisture and the insalubrious quality of the drinking water. All these islands are, generally speaking, hilly and broken. The industry of the locality is in collecting Salanganes (edible birds' nests), honey, and wax; but cultivation is not practiced to any great extent. The forests produce good timber for building or cabinet work.
Tara Island, when seen from the northward, shows a triple summit to its northwest end; while its southern part looks like a separate island, saddle-shaped. The island does not appear to be permanently inhabited; in March, 1885, it was occupied by parties from Busuanga, burning the grass and digging cassava.
Lagat is a small island 334 feet high, surrounded by a reef with a narrow passage between it and the reef off the south of Tara.
Botak Island, 800 feet high, is fairly well cultivated. Off its northern end there is a queer pin-shaped rock, and off its southern end are same sharp-pointed rocks. The vicinity has not been sounded.
The space included between the Sulu Archipelago to the south and Mindoro to the north, and having the Philippine Islands on the east and Palawan on the west, is distinguished by the name of the Sulu Sea. Although of great depth, 2,550 fathoms, this sea, which is in connection with the China and Celebes seas, and also with the Pacific by San Bernardino and Surigao straits, has a minimum deep-sea temperature of 50.5 degrees, reached invariably at 400 fathoms. As this temperature in the China Sea is at the depth of 200 fathoms, and in the Celebes Sea at 180 fathoms, and in the Pacific at 230 fathoms, it may be inferred that the Sulu Sea is prevented from freely interchanging its waters with those seas by ridges which do not exceed those depths.
In the Sulu Sea easterly winds with fine weather prevail in October, and the northeast monsoon is not established until November. In January and February it blows hardest, but not with the force of the China seas, and it is felt strongest before the openings between Panay and Negros, and Negros and Mindanao. At the end of May southwest winds begin to blow, and in a month become established, to terminate in October, bringing with them a season made up of rain squalls and tempests, which take place principally in July and August. In September a heavy mist hangs about the coast of Mindanao.
The island and province of Paragua is the most western of the Philippine Archipelago, and is situated to the north of Borneo. It is long and narrow, following a northeast direction, and nearly closes on the southwest the Sea of Mindanao, which enters from the China Sea by Balabac Strait on the south and between Mindoro and Paragua on the north. A chain of high mountains, some 6,560 feet high, runs lengthwise of the narrow belt formed by the island, whose length is 266 miles. The northwest and northeast slopes are narrow. The island has extensive and well protected harbors and bays. The area is 2,315 square miles and the population 45,000.
The capital is Puerto Princesa, with a population of 1,589.
Panay is divided into three provinces, viz: Capiz to the north, Iloilo to the southeast, and Antique to the southwest. In general it is wild, with very high coasts, except in the northeastern part, where the latter are somewhat marshy. A mountain chain crosses the island from Point Juraojurao on the south as far as Point Potol on the north, following a direction almost parallel to the western coast. Large groups of sierras branch out to the right and left of the central chain; on the eastern slope begins another chain, running northeast to the extreme northeasterly point of the island. Owing to its cragginess, it has a great number of streams running in different directions. The area is 4,540 square miles.
The town of Iloilo stands on a low sandy flat on the right bank of a river; at the end of this flat is a spit on which a fort is built, and close to which there is deep water. Vessels of moderate draft (15 feet) can ascend the river a short distance and lie alongside wharves which communicate with the merchant houses, but large vessels must anchor outside near the spit. It is a town of great commercial importance, and a brisk coasting trade is carried on from it. The better class of houses in Iloilo are built on strong wooden posts, 2 or 3 feet in diameter, that reach to the roof; stone walls to the first floor, with wooden windows above, and an iron roof. The poorer class of dwellings are flimsy erections of nipa, built on four strong posts. The roads and bridges are in a deplorable condition and almost impassable in the rainy season.
The chief imports are Australian coal, and general merchandise from
Europe, but most sailing ships arrive in ballast.
The exports are sugar, tobacco, rice, coffee, hides, and hemp; it is also the principal place of manufacture of pina, juse, and sinamoya, a tissue greatly in use among the Philippines. In 1883, 93,750 tons of sugar were exported, principally to America.
Typhoons do not occur regularly, but in most years the tail of one passes over the place, which suffers also from the visitations of locusts.
Provisions of all kinds can be obtained, but the prices are higher than at Manila. In 1886 beef was 12 1/2 cents per pound, bread 11 cents, vegetables 11 cents, fowls $2 per dozen. Water is scarce and is brought across from Guimaras in tank boats; it is supplied to the shipping at the rate of $1 per ton; the Europeans depend mainly upon rain water.
There are generally about 500 tons of coal in store, chiefly Australian; it is kept for the supply of local steamers that take in what they require alongside the wharves. Vessels in the roads can have it brought off in bulk in lighters or schooners at a cost of 50 cents a ton. Coolies can be hired at 75 cents per ton, but they will not coal vessels if they can get other work. Notice is required the day before coaling, as men are not kept in readiness. The price of coal in 1886 was $11.00 per ton.
There is regular weekly communication with Manila, which is 250 miles distant.
The Province of Capiz is bounded on the north by the Archipelago Sea, on the east by the District of Concepcion, on the south by the ridge separating it from Iloilo, and on the southwest by the mountains, separating it from the Province of Antique. Its very high mountains are covered with luxuriant vegetation, and give rise to many rivers which water the valleys of the province. There are gold and copper mines, and much tobacco, sugar, rice, and abaca is raised. During the year three fairs are held, in which articles of the country are bartered. The province is divided into two parts, called Ilaya and Aclan, which are irrigated by the rivers Panay and Adan, respectively. The area is 1,543 square miles and the population 189,171, distributed among 36 pueblos and 287 barrios.
The capital is Capiz, with a population of 13,676. It is situated 290 miles from Manila. It has a harbor for vessels of ordinary draft, and highroads to Iloilo, Antique, and the District of Concepcion. There is a steamer kept by the state, stopping at the harbor every 28 days and keeping up communication with Manila, Romblon, Iloilo, and Cebu.
The Province of Iloilo is to the southeast of the Province of Capiz and west of Antique. The ground is generally level, and, being irrigated by numerous rivers, is fertile, so that tobacco, cacao, sugar cane, abaca, rice, and maize are grown; besides, there is good pasturage for raising herds of cattle and horses, and gold and other mines are known. The principal industry is the manufacture of fabrics of sinamay, pina, jusi, etc., requiring over 30,000 looms. The dimensions are 99 miles in length by 27 miles in width, and the population is 472,728.
The capital is Iloilo, with a population of 10,380. It is situated 355 miles from Manila, and is the residence of the governor, captain of port, and a number of treasury, justice, and fomento officials. It has a pretty cathedral, a seminary, casa real, and court house. It is one of the most mercantile towns of the Visaya group, and has some industries, among which are a machine shop and foundry, a carriage factory, and a hat factory.
The Province of Bohol is bounded on the north by the sea between Cebu and Leyte, on the east by the Surigao Sea, on the south by the Sea of Mindanao, and on the west by the channel separating it from Cebu. The province is composed of the islands of Bohol and Dauis. They are somewhat mountainous and well wooded, and coffee, abaca, sugar cane, and tobacco are raised. In the mountains of Bohol game is plenty, and many coal and phosphate of iron mines are supposed to exist. Manufactures consist in fabrics of sinamay and other materials. The area is 1,617 square miles and the population 247,745.
The capital is Tagbilaran, with a population of 8,638. It is situated 365 miles from Manila.
The island and province of Cebu are the most important of the Visayas, on account of the central position, nature of the soil, and the industry of its numerous inhabitants. It is bounded on the north by the sea separating it from Masbate and Leyte, on the east by the sea separating it from Leyte and Bohol, on the south by the Mindanao Sea, and on the west by the Tanon Channel and the island of Negros. The area is 2,092 square miles and the population 504,076. Great mountain chains cross the island; the chief of these starts at the extreme north between Point Marab on the west and Baluarte on the east, and, continuing south between the two coasts, ends almost in the center of the island. Two other chains run along the coast, and one starts near Carcas, to the southwest of the city of Cebu, terminating on the south in Tanon Point. The coasts are high and the rivers of little importance.
The capital is Cebu, with a population of 35,243. It is the mercantile center of the islands, and is situated 460 miles from Manila. It is an Episcopal see, and has a good cathedral, Episcopal palace, casa real, court house, and private edifices, simple but tasty; there is also a post office and telegraph station. On the south, and at the entrance of the channel, is the castle of Point Cauit, and north of this the tower of Mandaui; both these fortifications communicate with the capital by means of a wagon road, the city being midway between them. At the capital reside the politico-military governor, a secretary, judge and attorney-general, a number of public functionaries, a captain of engineers, and the captain of the port.
Maktan Island consists of an old coral reef, raised a few feet (8 or 10 at most) above the present sea level. At the northern part of the island, where a convent stands, a low cliff fringes the shore, being an upper stratum of the upheaved reef. The raised reef is here preserved, but over the portion of the island immediately fronting Cebu it has been removed by denudation, with the exception of a few pillar-like blocks which remain, and which are conspicuous from the anchorage. The surface is scooped out into irregular basins and sharp projecting pinnacles and covered in all directions with mud, resulting from the denudation. Nearly all the island is covered by mangroves, but on the part left dry there are plantations of cocoanuts.
The only town on the island is Opon, on the west coast, SW. of Mandaui Point in Cebu. It was here that Magellan was killed in 1521, after making the first passage across the Pacific.
The town of Cebu is the most ancient in the Philippines; it is the seat of government of the Visayan Islands, which include Cebu, Bohol, Panay, Negros, and Leyte, and it is the residence of a bishop. It is built on a large plain at the foot of the chain of hills that traverse the island throughout its length, and is a well-constructed, thriving place; the merchants' quarter is situated along the port, and includes some well-built stone houses, though many are of old construction. The huts of the Malays, for the most part fishermen, are on the beach, and form the west part of the city. The fort is a triangular edifice of stone, painted red, with an open square in front.
The island of Leyte is bounded on the north by the canal separating it from Samar, on the east by the Pacific Ocean, on the west by the sea separating it from Bohol and Cebu, and on the south by the one separating it from Mindanao. It is extensive and irregular, having an area of 3,087 square miles and a population of 270,491. A high and abrupt mountain chain crosses the island nearly parallel to the west coast; the coasts are high, with good natural harbors. In the northern part and on the western slopes of the great sierras, streams of potable water and also many lagoons abound. This is different from the eastern part, where the latter are scarce. The principal product of the island is abaca, but rice is also raised and cocoanut oil is extracted. There are unworked mines of gold, magnetite, and sulphur.
The capital is Tacloban, with a population of 5,226. It is situated 338 miles from Manila. Among the important towns are Baru, population 12,222; Borauen, 21,290; Cauyaia, 13,732; Dagami, 25,000; Hilongos, 13,713; Jaio, 12,475; Massiu, 18,499; Palo, 17,736; Tauauau, 18,509.
The island of Negros is mountainous and wild; its coasts are difficult of access, and the breakers strong, except on the west coast from Point Bulucabo on the north of Palompon on the west, where it is marshy. A high mountain chain crosses it from Point Doong on the north to the harbor and point Bombonon on the south; from the last third extend several ramifications of high mountains, terminating on the coast at the extreme south and in the Sierra Dumaguete. Its streams are not important, being short and of little value. The ground is uneven but fertile. The natives irrigate their estates, and produce tobacco, coffee, sugar cane, and wheat. Manufactures consist in fabrics of abaca and canonegro, of which boat cables are made. The interior of the island, covered with thick forests, is almost unexplored, being inhabited by a few savages.
The Province of Western Negros is situated on Negros Island, it is bounded on the north by the Visayas Sea, on the west by the Paragua Sea, and on the south and east by the Province of Eastern Negros. The area is 1,929 square miles, and the population 226,995.
The capital is Bacolod, with a population of 6,268. It is the residence of the politico-military governor, the secretary, judge, attorney-general, and several public functionaries.
It is situated 379 miles from Manila.
The Province of Negros has a population of 94,782—the capital,
Dumaguete, 13,613.
The Province of Romblon consists of the following six islands: Romblon (the principal one), Tablas, Sibuyan, Banton, Simara, and Maestre Campo. It is bounded on the north by the Tayabas Sea, on the south by the Visayas Sea, on the east by the Sea of Masbate, and on the west by the Sea of Mindoro. The area is 813 square miles, and the population 38,633, distributed among 13 barrios and 3 rancherias of infieles.
The capital is Romblon, with a population of 6,764. It is situated on the harbor of the same name at the north of the island, 204 miles from Manila, and is the residence of the politico-military commander.
The Island and Province of Samar is situated to the southeast of Luzon, it is bounded en the north by the Strait of San Bernardino, on the south by the Jahanetes Canal, separating it from Leyte Island, on the east by the Pacific Ocean, and on the west by the Visayas Sea. It is very mountainous, with high, steep coasts. A number of sierras and mountains extend in various directions, forming valleys and glens fertilized by numerous rivers, which, however, have little current and volume. The length of the island is 155 miles. The chief products are abaca, rice, and cocoanuts, oil being extracted from the latter. Among the medicinal plants the most highly valued is the catbalonga seed. Commerce is quite active in spite of the few means of communication and the dangerous coasts. The island is visited yearly by tornadoes which devastate crops and cause much damage to agriculture. The high mountains and thick forests of the interior are inhabited by a great number of savages who have sought refuge here. The area is 4,699 square miles, and the population 200,753, distributed among 43 pueblos, 208 visitas, and 3 rancherias of subdued infieles.
The capital is Catbalogan, population of 6,459, situated on the harbor and bay of like name on the west of the island 338 miles from Manila, and is the residence of the politico-military governor.
The Jolo Archipelago, formed of some 160 islands, is situated southwest of Mindanao and south of Basilan. It is bounded on the south by the Jolo Sea, on the northeast by Mindanao and on the west and southwest by Borneo. The small islands are covered with mangroves, while the large ones have thick forests of good timber, and the natives raise rice, maize, and various alimentary roots, ambergris being found on the coasts. The principal island, called Sulu, or Jolo (ch. 47, 48, 49, 50, p. 285), is occupied in a military way by the Spanish forces, whose chief, or governor, resides in the old capital, which has well-constructed and armed forts, a pier, etc. By royal decree of November 13, 1877, the sultanship was transformed into a civico-military government. The population consists of 500 aborigines, 612 Chinese traders, and 16,000 negroes.
Next to Luzon, the island of Mindanao is the most extensive and important of the Philippines.
By decree of July 30, 1860, the territorial division of this island was definitely established, and a civico-military government, under the denomination of Mindanao and adjacent islands, was created. It is divided into eight districts. The island is situated between Visayas on the north and Borneo on the south; it is bounded on the east by the Pacific Ocean, and on the west by the island of Paragua, the Strait of Balabac, and Borneo. The area is 16,595 square miles, and the population 611,300, of which 211,000 are Christians and the rest Mohammedans and Pagans. It is very extensive and irregular in form, possessing high and extended mountain chains, which have not been entirely explored, and which are grown over with very rich woods. It is inhabited almost throughout the interior by savages. Its rivers, some of great volume, are as follows: On the north coast and Butuan Bay, the Jabonga and Butuan: on the Macajalar coast, the Cagayan; in Eligan Bay, the Malanao and others of minor importance; in the cove of Dapitan, the Palaven.
In Port Kakule the greatest rise of tide is seven feet. In Surigao Strait the flood tide sets to the west, and the ebb to the east. The velocity of the stream in the strait reaches six knots at springs. There is a difference of about two hours between the time of high water at Surigao and in Surigao Strait. Fishermen roughly estimate that when the moon rises the ebb tide commences to run in Surigao Strait. From January to June there is but one high water during the twenty-four hours, in Surigao Strait, which occurs during the night. From July to December the same phenomenon takes place, but the time of high water is by day.
From observations made by the Spanish surveyors, it appears that the highest tide on the west coasts of the islands of the strait takes place at the same hour as the lowest tide on the east coasts.
The Mindanao river disembogues five miles to the south of Palak Harbor by two wide arms, on the northernmost of which is the town of Kota-batu, about 5 1/2 miles from the mouth. The river is navigable for 60 miles by vessels of 3 1/2 feet draught; it flows through a beautiful valley 30 miles in width, which scarcely shows any change of level; the valley is capable of producing tobacco, cacao, sugar, maize, and cotton; but this is only known at present by specimens produced. The course of the river lies SE. for 45 miles from its mouth to the lake Ligauasan, out of which it is seen to flow; from the other side of the lake the direction of the river is NNE. to its source in the Sugut Mountains. At 21 miles from the northern mouth the river divides into two arms, which enter the sea 4 1/2 miles apart.
In the northern part of Mindanao is the province of Surigao, bordered on the north by the Surigao Sea, on the east by the Pacific, on the south by the District of Davao, and on the west by the territory of the infieles. It is mountainous, but the Christian population resides on the coasts and in the northern point of the territory. The population is 95,775, distributed among 45 pueblos, 10 barrios, and 30 rancherias of subdued infieles. Abaca and palay are raised, and in the gold washings considerable gold of good quality is found.
Military notes on the Philippines affirm that the islands are, in many respects, Spain's best possessions, due to the abundance and variety of products, numerous and good ports, character of inhabitants, and on account of the vicinity of certain countries of eastern Asia, which are now entering upon a stage of civilization and commerce. The group is composed of some 2,000 islands. In 1762 Manila was taken and held by the English for a ransom of 1,000,000 pounds sterling. This, however, was never paid, and the islands were finally returned to Spain.
The archipelago extends from 5 degrees 32 minutes to 19 degrees 38 minutes, north latitude, and from 117 degrees to 126 degrees, east longitude. It thus covers about 1,000 miles north and south and 600 east and west.
The whole surface of the Philippines is essentially mountainous, the only plains that occur being alluvial districts at the river mouths and the spaces left by the intersection of the ranges. The principal ranges have a tendency to run north and south, with a certain amount of deflection east and west, as the case may be, so that the orographic diagram of the archipelago, as a whole, has a similarity to a fan, with northern Luzon as its center of radiation.
While none of the mountain peaks greatly exceed 8,000 feet in height, Apo, in Mindanao, is over 9,000 feet; Halson, in Mindoro, is over 8,900 feet; and Mayon, in Luzon, over 8,200. The latter is an active volcano, which has been the scene of several eruptions during the present century. Extinct or active craters are relatively as numerous in the Philippines as in the eastern archipelago, and as a consequence of these subterranean forces earthquakes are frequent and violent.
In 1627 one of the most elevated mountains of Cagayan disappeared, and on the island of Mindanao, in 1675, a passage was opened to the sea and a vast plain emerged. The more recent of the convulsions occurred in 1863 and in 1880. The destruction of property was great, especially in Manila.
The general belief is that the Philippines once formed a part of an enormous continent from which it was separated by some cataclysm. This continent probably extended from Celebes to the farthest Polinesian islands on the east, to New Zealand on the south, and the Mariana and Sandwich islands on the north.
These islands, according to Ramon Jordana, are divided into two volcanic regions, the eastern and the western. The principal point is the volcano Taal, located in the northeastern portion of the province of Batangas. It is situated on a small island in the center of the Bombon laguna, and has an altitude of 550 feet above sea level. Its form is conical, and the rock is composed of basalt feldspar with a small quantity of augite. The crater is supposed to be 232 feet deep. Its sides are almost vertical, and there are two steaming lagunas at its bottom.
In the regions embracing the provinces of Manila, Bulacan, Pampanga, Tarlac, and Pangasinan the soil is mostly composed of clay containing remnants of sea shells, a circumstance which gives rise to the belief that the coast of Manila has risen from the sea in not so remote an epoch. Smooth, dark gray tophus predominates; it forms the bed of the Rio Pasig, and rising forms hillocks in the vicinity of the city of Binangonan. Farther on, trachyte and banks of conchiferous sand predominate.
The vast plain of Panpanga extends to the north of Manila Bay, to the south of which is situated Mount Arayat, of doleritic nature.
The disposition of the mountain ranges in parallel chains affords space for the development of streams both in Luzon and Mindanao. The larger islands contain inland seas, into which pour countless small streams from the inland hills. Many of them open out into broad estuaries, and in numerous instances coasting vessels of light draft can sail to the very foot of the mountains. Rivers and inland lakes swarm with varieties of fish and shellfish. By reason of Spanish restrictions, but little can be said as to the character of the stream banks and beds. Four of the rivers are navigable, and, by the statements of those who have spent some little time on the islands, most are fordable. Drinking water is obtained by many of the towns from the rivers at points just above tide limits, and the water is said to be good. Bridges are few and crude, but are generally built to withstand heavy strain.
The island of Luzon abounds in rivers and streams. The following are the principal water courses:
Rio Grande de Cagayan, the source of which is in the northern slope of the Caraballo Norte. It has numerous affluents, among others the Magat and Bangag, and, after a course of about 200 miles, falls into the China Sea in the vicinity of Aparri.
Agro Grande starts in the north, in the neighborhood of the ranch of Loo, receives the affluents Tarlag and Camiling, as well as many others, has a course of about 112 miles, and falls into the Gulf of Lingayen.
Abra has its origin on the opposite slope to that where Agno Grande takes its rise; runs for about 87 miles, and, after receiving the affluent Suyoc, divides into three arms and falls into the China Sea over the sand bars of Butao, Nioig, and Dile.
Rio Grande de la Pampanga is called Rio Chico up to the lake of Canasen, near Arayat, where it changes its name after its junction with Rio Gapan. Its course is a little over 38 miles; it receives the Rio de San Jose and divides into a multitude of arms as it falls into the sea to the north of Manila Bay.
Rio Pasig has its source in the Bay Lagoon, and falls after a course of 19 miles into Manila Bay.
The military notes on the climate of the Philippines, the official record of the temperature and the gales and typhoons, and directions regarding the handling of ships in the peculiar tempests that prevail at certain seasons around the islands, are of absorbing popular interest, and of striking special usefulness.
Climate.—In the region of Manila, the hottest season is from March to June, the greatest heat being felt in May before the rains set in, when the maximum temperature ranges from 80 degrees to 100 degrees in the shade. The coolest weather occurs in December and January, when the temperature falls at night to 60 or 65 degrees, and seldom rises in the day above 75 degrees. From November to February the sky is bright, the atmosphere cool and dry, and the weather in every way delightful. Observations made at the Observatortio Meteorologico de Manila have been compiled by the United States Weather Bureau, covering a record of from seventeen to thirty-two years, from which the following is an extract:

Seasons vary with the prevailing winds (monsoons or trade winds) and are classed as "wet" and "dry." There is no abrupt change from one to the other, and between periods there are intervals of variable weather.
The Spanish description of seasons is as follows:
Seis meses de lodo—six months of mud.
Seis meses de polvo—six months of dust.
Seis meses de todo—six months of everything.
The northern islands lie in the track of the typhoons which, developing in the Pacific, sweep over the China Sea from NE. to SW. during the southwest monsoon. They may be looked for at any time between May and November, but it is during the months of July, August, and September that they are most frequent. Early in the season the northern region feels the greatest force, but as the season advances the typhoon gradually works southward and the dangerous time at Manila is about the end of October and the beginning of November. Typhoons rarely, if ever, pass south of 9 degrees N. latitude. Sometimes the typhoon is of large diameter and travels slowly, so far as progressive movement is concerned; at others it is of smaller dimensions, and both the circular and progressive motions are more rapid. However they are always storms of terrific energy and frequently cause terrible destruction of crops and property on shore and of shipping at sea. Thunderstorms, often of great violence, are frequent in May and June, before the commencement of the rainy season. During July, August, September, and October the rains are very heavy. The rivers and lakes are swollen and frequently overflow, flooding large tracts of low country.
At Manila the average rainfall is stated to be from 75 to 120 inches per annum, and there the difference between the longest and shortest day is only 1 hour 47 minutes and 12 seconds. This rainfall, immense though it be, is small as compared with that of other parts of the archipelago; e.g., in Liano, NE. of Mindanao, the average yearly downpour is 142 inches.
Gales.—The gales of the Philippines may be divided into three classes, known by the local names of Colla, Nortada, and Baguio. The Colla is a gale in which the wind blows constantly from one quarter, but with varying force and with alternations of violent squalls, calms, and heavy rains, usually lasting at least three days; these gales occur during the southwest monsoon and their direction is from the southwest quarter. The Nortada is distinguished from the Colla, in that the direction is constant and the force steady, without the alternations of passing squalls and calms. The Nortada is generally indicative that a typhoon is passing not very far off. These gales occur chiefly in the northern islands, and their direction, as the name implies, is from the northward. Baguio is the local name for the revolving storm known as the typhoon, which, being the more familiar term, will be used in these notes.
Typhoons.—These storms have their origin to the east or to the southeast of the Philippines, whence their course is westward, with a slight divergence to the north or south, the average direction appearing to be west by north. They occur in all months of the year, but the greater number take place about the time of the equinoxes. The most violent ones occur at the autumnal equinox, and on an average, two or three occur every year, and sometimes one follows another at a very short interval. It is believed that when one of these typhoons passes a high latitude in September there will be another in October of that year, and one may be looked for in November in a lower latitude. These tempests are not encountered in latitudes below 9 degrees N. The rate of progress of these storms is about 13 miles an hour; in none of those observed has it exceeded 14 miles nor fallen below 11 miles. The diameter of the exterior revolving circle of the storm varies from 40 to 130 miles, and the diameter of the inner circle or calm region, may be estimated at from 8 to 15 miles. The duration of the true typhoon at any one place is never longer than ten hours and generally much less. These storms are always accompanied by abundant rain, with low, dense clouds, which at times limit the horizon to a few yards distance, and are generally accompanied by electrical discharges. The barometer falls slowly for some days before the typhoon, then falls rapidly on its near approach, and reaches its lowest when the vortex is but a little way off. It then rises rapidly as the vortex passes away, and then slowly when it has gained some distance. Near the vortex there are usually marked oscillations. The typhoon generally begins with a northerly wind, light drizzling rain, weather squally and threatening, a falling barometer and the wind veering to the eastward, when the observer is to the northward of the path of the storm, and backing to the westward when he is to the southward of it; the wind and rain increase as the wind shifts, and the storm generally ends with a southerly wind after abating gradually.
The following warnings of the approach of a typhoon, and directions for avoiding the most dangerous part of it, are taken from the China Sea Directory: The earlier signs of a typhoon are clouds of a cirrus type, looking like fine hair, feathers or small white tufts of wool, traveling from east or north, a slight rise in the barometer, clear and dry weather, and light winds. These signs are followed by the usual ugly and threatening appearance of the weather which forbodes most storms, and the increasing number and severity of the gusts with the rising of the wind. In some cases one of the earliest signs is a long heavy swell and confused sea, which comes from the direction in which the storm is approaching and travels more rapidly than the storm's center. The best and surest of all warnings, however, will be found in the barometer. In every case there is great barometric disturbance. Accordingly, if the barometer falls rapidly, or even if the regularity of its diurnal variation be interrupted, danger may be apprehended. No positive rule can be given as to the amount of depression to be expected, but at the center of some of the storms the barometer is said to stand fully 2 inches lower than outside the storm field. The average barometric gradient, near the vortex of the most violent of these storms, is said to be rather more than 1 inch in 50 nautical miles. As the center of the storm is approached the more rapid become the changes of wind, until at length, instead of its direction altering gradually, as is the case on first entering the storm field, the wind flies around at once to the opposite point, the sea meanwhile breaking into mountainous and confused heaps. There are many instances on record of the wind suddenly falling in the vortex and the clouds dispersing for a short interval, though the wind soon blows again with renewed fury.
In the northern hemisphere when the falling barometer and other signs create suspicion that a typhoon is approaching, facing the wind and taking 10 or 12 points to the right of it, will give the approximate bearing of its center. Thus, with the wind NE., the center will probably be from S. to SSE. of the observer's position. However, it is difficult to estimate the center of the vortex from any given point. This partly arises from the uncertainty as to the relation between the bearing of the center and the direction of the wind, and greatly from there being no means of knowing whether the storm be of large or small dimensions. If the barometer falls slowly, and the weather grows worse only gradually, it is reasonable to suppose that the storm center is distant; and conversely, with a rapidly falling barometer and increasing bad weather the center may be supposed to be approaching dangerously near.
Practical Rules.—When in the region and in the season of revolving storms, be on the watch for premonitory signs. Constantly observe and carefully record the barometer.
When on sea and there are indications of a typhoon being near, heave to and carefully observe and record the changes of the barometer and wind, so as to find the bearing of the center, and ascertain by the shift of the wind in which semicircle the vessel is situated. Much will often depend upon heaving to in time. When, after careful observation, there is reason to believe that the center of the typhoon is approaching, the following rules should be followed in determining whether to remain hove to or not, and the tack on which to remain hove to:
In the northern hemisphere, if the right-hand semicircle, heave to on the starboard tack. If in the left-hand semicircle, run, keeping the wind if possible, on the starboard quarter, and when the barometer rises, if necessary to keep the ship from going too far from the proper course, heave to on the port tack. When the vessel lies in the direct line of advance of the storm—which position is, as previously observed, the most dangerous of all—run with the wind on the starboard quarter. In all cases increase as soon as possible the distance from the center, bearing in mind that the whole storm field is advancing.
In receding from the center of a typhoon the barometer will rise and the wind and sea subside. It should be remarked that in some cases a vessel may, if the storm be traveling slowly, sail from the dangerous semicircle across the front of the storm, and thus out of its influence. But as the rate at which the storm is traveling is quite uncertain, this is a hazardous proceeding, and before attempting to cross the seaman should hesitate and carefully consider all the circumstances of the case, observing particularly the rate at which the barometer is falling.
Northward of the Equator the current is divided into north and south equatorial currents by the equatorial counter-current, a stream flowing from west to east throughout the Pacific Ocean. The currents in the western part of the Pacific, to the northward of the Equator, are affected by the monsoons, and to the southward of the Equator they are deflected by the coast of Australia.
The trade drift, which flows to the westward between the parallels of 9 degrees and 20 degrees N., on reaching the eastern shores of the Philippine Islands again turns to the northward, forming near the northern limit of that group the commencement of the Japan stream. The main body of the current then flows along the east coast of Formosa, and from that island pursues a northeasterly course through the chain of islands lying between Formosa and Japan; and sweeping along the southeastern coast of Japan in the same general direction, it is known to reach the parallel of 50 degrees N. The limits and velocity of the Japan stream are considerably influenced by the monsoons in the China. Sea, and by the prevailing winds in the corresponding seasons in the Yellow and Japan seas; also by the various drift currents which these periodic winds produce.
Admiral Dewey has forwarded to the navy department a memorandum on mineral resources of the Philippines prepared at the admiral's request by Professor George W. Becker of the United States geological survey. Only about a score of the several hundred islands, he says, are known to contain deposits of valuable minerals. He includes a table showing the mineral bearing islands and their resources. This table follows:
"Luzon, coal, gold, copper, lead, iron, sulphur, marble, kaolin; Sataanduanes, Sibuyan, Bohol and Panaoan, gold only; Marimduque, lead and silver; Mindoro, coal, gold and copper; Carraray, Batan, Rapu Rapu, Semarara, Negros, coal only; Masbete, coal and copper; Romblon, marble; Samar, coal and gold; Panay, coal, oil, gas, gold, copper, iron and perhaps mercury; Biliram, sulphur only; Leyte, coal, oil and perhaps mercury; Cebu, coal, oil, gas, gold, lead, silver and iron; Mindanao, coal, gold, copper and platinum; Sulu archipelago, pearls."
The coal, Mr. Becker says, is analogous to the Japanese coal and that of Washington, but not to that of the Welsh or Pennsylvania coals. It might better be characterized as a highly carbonized lignite, likely to contain much sulphur as iron pyrites, rendering them apt to spontaneous combustion and injurious to boiler plates. Nevertheless, he says, when pyrites seams are avoided and the lignite is properly handled, it forms a valuable fuel, especially for local consumption.
Not least among the promising resources of the Philippines is a curious natural product. Several vegetable growths appear to possess the faculty of secreting mineral concretions, in all respects resembling certain familiar precious stones. The famous James Smithson was the first to give any real attention to these curious plant gems, but, though there can be no doubt of their authenticity, neither scientist nor merchant has followed this lead. One of the jewels, the bamboo opal, rivals the best stones in its delicate tints of red and green, but it is among the rarest, and 1,000 stems may be cut up before a single specimen be found.
