My first duty in connection with this survey was recording the readings of the transit, operated by the officer in charge. Our route led through the “barrios” of Marilao, Santa Maria, Tomano, Buena Vista, San Jose, Bagbaguen, Prensa, and Santa Cruz, in the province of Bulacan. The heat endured on these expeditions was intense, especially along the rice-dikes, which were barren of foliage. Occasionally, when in the vicinity of a barrio where we had but one night to remain, instead of spreading canvas we bivouacked under the roof of some convenient casa. On one occasion, having worked until sundown, our cartello was drawn alongside of an old native house of worship, in the barrio of Buena Vista, where a “fiesta” had been in progress for several days. Here, under the eaves of this sacred shrine, this soldier outfit dined “A la cartello.” In the interior of this sanctuary, the flickering lights in a large candelabrum, at the base of the crucifix, shone dimly through the gloom. With a feeling of absolute safety, the soldiers spread their ponchos over the bamboo matting and, wrapped in blankets, reposed in peaceful slumber. There was nothing to disturb the tranquillity of this night until, shortly before the break of dawn, we were aroused by the tolling of the bells, and the chanting of the Ave Maria, uttered in solemn devotion by a long procession of natives garbed in ceremonious black, preceded by a señorita bearing a cross, flanked on either side by torch-bearers. As the procession moved slowly down the aisle, the soldiers arose from their unusual berth and, occupying seats, observed the ceremonies with respectful silence. These natives were the thoroughbred Tagalogs, the aborigines of the Philippines, the greater number of them being converts to Roman Catholicism, the balance adhering to the doctrines of the Reformation, or the Protestant religion. Leaving Buena Vista, our route led through the beautiful Marquina Valley, with its immense forests of bamboo, ebony, sapan-wood, and gum-trees entwined by the bush-rope of palasan, trees teeming with the luscious mango and guava, bordering on plantations and groves of the vegetable kingdom, including the banana, plantain, sugarcane, pineapple, coffee, cinnamon, and tobacco.
