“ Most of the hemp (538,200 acres in 1902) is grown in south Luzon and in Samar and Leyte, but smaller crops are produced in Cebú, Mindoro, Marinduque, north Mindanao and south Negros; the crop became of commercial importance about 1855, and in 1907 the yield for export amounted to 112,895 tons. About two-thirds of the sugar is produced in Negros, but it is an important crop in the provinces of Pampanga and Tarlac, within the lowland basin of Luzon, also in the province of Batangas on the south coast of Luzon, in the south and east of Panay, and in Cebú. ”
