There are various animals in this kingdom, as for instance, carabaos or buffaloes, dogs, domestic and wild swine, monkeys, and goats, and many deer in the mountains. The Spaniards have brought here cows and horses. The cows have multiplied remarkably. The horses are numerous, and are small. It is a land of many reptiles and serpents; for it is damp and hot. In especial is there one species known as olopong. [81] There is no preservative or antidotal herb against its bite. Others [i.e., pythons] are called sauas, which are very large. One of these will hang from a tree, catch whatever living thing passes below--such as deer, man, or swine--and swallow it whole. It has a very large and excellent gall, which is a proved antidote for or preventive of [poison]. The mountain Indians eat that snake. It breeds in the mountains on the opposite coast of Valer and Palinan. The other animals above mentioned are numerous throughout the kingdom. In the same manner these islands abound in large and small fish. Tunnies are caught on the opposite coast of Casiguran and in the lake of Bong-bong--although as the country is so hot, few of them are in good condition when they reach Manila. The most remarkable fish is the crocodile, which here is called buhaya. It is a fierce animal, [living in both] land and water, and thus sustains itself by hunting and fishing, although it does not go far inland. The rivers and lakes are full of those animals. In the province of Camarines there is a lake of fresh water where there are so many crocodiles that the surrounding villages collect to kill them; and they are accustomed to kill fifty, sixty, or a hundred of the creatures. Their flesh is not eaten, and hence they are good for nothing. There are also various species of birds. They multiply but little, for the serpents eat them. The principal birds are fowls like those of España; other fowls, smaller like partridges, which breed in the mountains; many turtle-doves and pigeons, and anades [82] and ducks. There are but few metals. The Indians get gold from their mines. Our missions contain the mines of Paracali, and that village is supported by the gold that is obtained there, for it has no other resources. Those mines fill up immediately with water; and hence they are of no importance to the Spaniards. But the Indians who are plodding, and work little by little, get a sufficient quantity of it. A mine was discovered in that village some years ago, from which considerable gold was extracted. It filled with water and now a wonderful vein is seen there. Some Spaniards have attempted to draw off the water, because of the great wealth that it shows, but they have not succeeded. Another mine, of copper, was discovered in that same village of Paracale. [83] Some copper, though little, was obtained from it, and then it was abandoned because the cost was more than the profit. There is a prolific mine of rock sulphur in the province of Camarines.
