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.
