Like many other provinces Isabela Province was the scene of important uprisings. In 1763, for example, stirred by the influence of the Silang rebellion in Ilocos, the people of Isabela revolted, led on by Dabo and Juan Morayac. The centers of rebellion were Ilagan and Cabagan. Again in 1785, another revolt broke out. This time the rebellion was led by Labutao and Baladon. The rebellion was caused by the grievances of the people against the collection of tribute and the enforcement of the tobacco monopoly. The historical spot of Isabela is the little town of Palanan on Palanan Bay, on the Pacific Coast. The bay is exposed to the weather and the anchorage is reefy, while the town is separated from the rest of the province by great mountains which make communication and travel difficult and dangerous. It was in this town that General Emilio Aguinaldo retreated and maintained his headquarters until his capture by General Funston by a ruse in March, 1901. [Salinas Salt Springs] NUEVA VIZCAYA PROVINCE is south of Cagayan on the Pacific Coast of Luzon. It contains vast areas of fertile public lands suitable for rice, tobacco, sugar, coconuts, beans, potatoes, coffee, and abaca, practically untouched, as well as virgin forests filled with all classes of valuable timber. The province is the gateway to and granary of the tobacco-producing provinces to the north. The climatic conditions of the province are unsurpassed. There are places the climate of which is similar to that of Baguio. There are also places of scenic beauty, such as Salinas, which are not inferior to world-famous objectives of tourist travel. The salt springs at Salinas have been from time immemorial the source of this essential food element to the peoples of even distant regions. MINDORO PROVINCE is named after the Spanish phrase "mina de oro" or "gold mine," as mining is said to have once been a great source of wealth in the region. The province is co-extensive in territory with the Island of Mindoro, southwest of Luzon. Rice, copra, abacá, sugar, and corn are the principal products. Along the coast are extensive nipa swamps. [Mineral Deposits] Gold is found in the Rivers of Binabay, Baco, Bongabong, and Magasauan Tubig.
