Wild cotton is practically useless for spinning, as the staple is extremely short, but perhaps by hybridization and careful attention its culture might become valuable to the Colony. The pod is elliptical, and the cotton which bursts from it at maturity is snow-white. It is used for stuffing pillows and mattresses. It was a common thing, before the American occupation, to see (wild) cotton-trees planted along the highroad to serve as telegraph-posts; by the time the seed is fully ripe, every leaf has fallen, and nothing but the bursting pods remain hanging to the branches.
The Buri Palm is a handsome species, of tall growth, with fan-like leaves. Its juice serves as a beverage resembling tuba. The trunk yields a sago flour. The leaves are beaten on boulder stones to extract a fibre for rope-making, of great strength and in constant demand.
The Ditá Tree, said to be of the family of the Apocynese and known to botanists as Alstonia scholaris, is possibly a species of cinchona. The pulverized bark has a bitter taste like quinine, and is successfully used by the natives to allay fever. A Manila chemist once extracted from the bark a substance which he called ditaïne, the yield of crystallizable alkaloid being 2 per cent.
Palma Brava (Coripha minor) (Tagálog, Ban͠ga),[7] is a species of palm, the trunk of which is of great local value. It is immensely strong, and will resist the action of water for years. These trees are employed as piles for quay and pier making—for bridges, stockades, and in any works where strength, elasticity, and resistance to water are required in combination. When split, a fibrous pith is found in the centre much resembling cocoanut coir, but the ligneous shell of the stem still retains its qualities of strength and flexibility, and is used for vehicle-shafts, cooliesʼ carrying-poles, and a variety of other purposes.
Bambusa (Bambusa arundinacea) is a graminifolious plant—one of the most charmingly picturesque and useful adornments of Nature bestowed exuberantly on the Philippine Islands. It grows in thick tufts in the woods and on the banks of rivers. Its uses are innumerable, and it has not only become one of the articles of primary necessity to the native, but of incalculable value to all in the Colony.
There are many kinds of bamboos, distinct in formation and size. The Tagálog generic name for knotted bamboo is Cauáyan; the Spanish name is Caña espina. The most common species grows to a height of about 60 feet, with a diameter varying up to eight inches, and is of wonderful strength, due to its round shape and the regularity of its joints. Each joint is strengthened by a web inside. It is singularly flexible, light, elastic, and of matchless floating power. The fibre is tough, but being perfectly straight, it is easy to split. It has a smooth glazed surface, a perfectly straight grain, and when split on any surface, it takes a high polish by simple friction. Three cuts with the bowie-knife are sufficient to hew down the largest bamboo of this kind, and the green leaves, in case of extreme necessity, serve for horsesʼ fodder.
There is another variety also hollow, but not so large as that just described. It is covered with a natural varnish as hard as steel. It is also used for native cabin-building and many other purposes.
A third species, seldom found more than five inches in diameter, is much more solid, having no cavity in the centre divided by webs. It cannot be applied to so many purposes as the first, but where great strength is required it is incomparable.
When the bamboo-plant is cultivated with the view of rendering it annually productive, the shoots are pruned in the dry season at a height of about seven feet from the ground. In the following wet season, out of the clump germinate a number of young shoots, which, in the course of six or eight months, will have reached their normal height, and will be fit for cutting when required. Bamboo should be felled in the dry season before the sap begins to ascend by capillary attraction. If cut out of season it is prematurely consumed by grub (gojo), but this is not much heeded when wanted in haste.
The northern native builds his hut entirely of bamboo with nipa palm-leaf or cogon thatching; in the Province of Yloilo I have seen hundreds of huts made entirely of bamboo, including the roofing. To make bamboo roofing, the hollow canes are split longitudinally, and, after the webbed joints inside have been cut away, they are laid on the bamboo frame-work, and fit into each other, the one convexly, the next one concavely, and so on alternately. In frame-work, no joinerʼs skill is needed; two-thirds of the bamboo are notched out on one side, and the other third is bent to rectangle. A rural bungalow can be erected in a week. When Don Manuel Montuno, the late Governor of Mórong, came with his suite to stay at my up-country bungalow for a shooting expedition, I had a wing added in three days, perfectly roofed and finished.
