In some cases they introduce seed-pearls or brilliant fish-scales in their work. The slippers worn by the women on grand occasions are often works of art, being richly embroidered in silver and gold on cherry coloured velvet. Some notable pieces of goldsmiths' and silversmiths' work have been done in Manila, and in the provinces some of the natives carve bolo handles and other articles out of buffalo horn and mount them in silver with much taste. The salacots, or native hats, are beautifully woven by hand from narrow strips of a cane called nito [lygodium], and the headmen have them ornamented with many pieces of repoussé silver (see Illustration). Cocoa-nut oil is expressed in the province of the Laguna, in Manila and other places. Soap of the ordinary kind is manufactured from it. Saddles and harness are made in all the leading towns, and the ordinary country vehicle, the carromata, is made in the chief towns of provinces and some others; but some of the components, such as the springs, and axle-arms and boxes are imported. But in Manila really elegant carriages are constructed, the leather for the hoods, the cloth for the linings, the lamps, as well as a good deal of the ironwork, being, however imported. In former years large frigates have been built, armed, and fitted out at Cavite and other ports, but at present the ship-building industry is in decadence, and the shipwrights capable of directing so important a job have died out. The increasing scarcity and high price of timber is now a difficulty, and sailing vessels are in little demand. Small steamers and launches are now built, but larger steamers are ordered from Hong Kong or Singapore, or, in case of vessels well able to make the passage, the order goes to England. The native craft called lorchas, pailebotes, pontines, barotos, paraos, cascos, guilálos, barangayanes, bangcas, vintas and salisipanes are still built in large numbers. The last are very light and fast craft used by the Moros on their piratical expeditions. Engines and boilers for steam launches are made in Manila, church bells are cast of a considerable size; iron castings are also made. Amongst the miscellaneous articles manufactured are all sorts of household furniture, fireworks and lanterns. Dentists, painters, sculptors and photographers all practise their trades.
