Najeeb M. Saleeby, The History of Sulu
“ The harbor is deep and free from currents. The bay is well protected on the north by the Islands of Pangasinan and Marongas and is safe from all storms except those from the northwest.Sulu occupies the most nearly central position of any island in eastern Malaysia. It lies between Mindanao on the east and Borneo on the west, and separates the Sulu Sea from the Celebes Sea. The commercial advantages of this position are unique. To the north lie the Bisayas, Palawan, Luzon, Formosa, China, and Japan; to the east Mindanao and Basilan; to the south, the Moluccas, Celebes, and Java ”
