I took special care not to forget the vade mecum which I always took with me, whenever I made these excursions for any number of days--I mean paper and a pencil, with which I made notes, to aid my recollections, and enable me afterwards to write down in a journal the remarks I made during my travels. Every preparation being made, we one morning started from Jala-Jala. We traversed the peninsula formed by my settlement, and embarked on the other side in a small canoe, which took us to the bottom of the lake to the north-east of my habitation. We passed the night in the large village of Siniloan, and at an early hour the following day resumed our march. This first day's journey was one of toil and suffering: we were then beginning the rainy season, and the heavy storms had swelled the rivers. We marched for some time along the banks of a torrent, which rushed down from the mountains, and which we were obliged to swim through fifteen times during the day. In the evening we came to the foot of the mountains where begin the forests of gigantic trees, which cover almost all the centre of the island of Luzon. There we made our first halt, lighted our fires, and prepared our beds and our supper. I think that I have already described our beds, which use and fatigue always rendered agreeable to us, when no accident occurred to disturb our repose. But I have said nothing of the simple composition of our meals, nor of our manner of preparing them. Our rice and palms required to be cooked, an operation which might seem rather embarrassing, for we had with us no large kitchen articles: we sometimes wanted a fire-box and tinder. But the bamboo supplied all these. The bamboo is one of the three tropical plants which Nature, in her beneficence and care, seems to have given to man to supply most of his wants. And here I cannot forbear dedicating a few lines to the description of those three products of the tropics, viz: the bamboo, the cocoa-nut tree, and the banana-plant. The bamboo belongs to the gramineous family; it grows in thick groves, in the woods, on the river banks, and wherever it finds a humid soil. In the Philippines there are counted twenty-five or thirty kinds, different in form and thickness. There are some of the diameter of the human body, and hollow in the interior: this kind serves especially for the construction of huts, and for making vessels to transport and to keep water. The filaments are used for making baskets, hats, and all kinds of basket-work, cords, and cables of great solidity. Another bamboo, of smaller dimensions, and hollow within, which is covered with varnish, almost as hard as steel, is employed in building Indian houses. Cut to a point it is extremely sharp, and is used for many purposes. The Indians make lances of it, and arrows, and fleams for bleeding horses, and lancets for opening abscesses, and for taking thorns or other things out of the flesh.
