The island is very rich in timber; all its hills and mountains are forest-clad to their summits. Excellent boats are constructed on the south and west coasts of the island which rival the Tawi-tawi boats in every particular. A few Americans have started hemp and coconut plantations on the north coast, but native cultivation is not extensive and compares very poorly with that of the Islands of Sulu, Tapul, and Siasi. Most of the cultivation on the island is carried on by Yakans, the Samals living chiefly on the products of the sea. The staple products of the soil are rice, tapioca, and corn. Ubi (a kind of tuber used as food), camotes (sweet potatoes), and wild fruits abound. The number of cattle is not inconsiderable, but horses are few. Most of the settlements on the island are on the sea coast and lie on the north and west coasts. The larger ones, beginning at Isabela and going east, are, on the north, Isabela, Patasan or Balaktasan, Malu'ung, Nipa, Lamitan, Tagima, and Kandi'is; on the east, Tambunan, Buhi-lubung, and Ubung; on the south, Amalwi, Giyung, and Mangal; on the west, Libuk, Kabkaban, Kanas, Malusu, and Pangasa'an; on the north, Bulansa, Atung-atung, Batanay, and Panigayan. [3] The prominent chiefs of the island live at Lamitan, Ubung, and Malusu, which form the principal centers of native power. The old name of Basilan was Tagima, so called after the name of the old settlement of Tagima mentioned above. Isabela may be considered as the capital of Basilan. Its old name is Pasangan, which is still the name of the stream at the mouth of which it is built. The town is situated 4 miles inland, on the narrow channel which separates Basilan from the small island of Malamawi. The channel widens a little at this point and forms an excellent harbor. Under Spanish jurisdiction it was a naval station with a dry dock for gunboats. An aqueduct furnishes the town with fresh water brought from a small stream in the neighborhood. The stone fort Isabel II, built on the hill in 1842, commands both entrances of the channel. It was designed to defend the town against the Moros. The abandonment of the town as a naval station has led to its present decline. An American sawmill planted there has been the chief source of lumber supply for the town of Zamboanga and neighborhood. The largest islands in this group, excepting Basilan, are Baluk-baluk and Pilas, both of which lie west of Basilan. A narrow channel which lies in the direct route leading from Zamboanga to Jolo separates these two islands. Tapiantana, Salupin, Bubwan, and Lanawan are the largest islands of the group south of Basilan. The population of this whole group is generally estimated at 25,000. Of these, 15,000 live in Basilan itself. The inhabitants of Basilan proper are Yakans and Samals, while the adjacent islands are occupied entirely by Samals. The Yakans are the aborigines of Basilan and extend farther into the interior than the Samals.
