Suyok is the gold mining center. Here is found one of the most striking features of the world. The whole side of a range of mountains, about 15 kilometers across, slides down to the valley, and on this slide, named the Palidan Slide, are found parts of gold veins which must have their connection somewhere else. The household industries are well developed. Clay products, such as pots, jars, and pipes are made for export. The men are experts in metal-working. They make weapons, pots, and spoons out of copper which they mine and smelt by native process. They also manufacture iron or steel spears, bolos, knives, and tools of all sorts, which they sell to or barter with the natives of the lowlands. They also carve wood into images, bowls, ornaments, and other utensils. The women make sufficient cloths for their own use and for sale. They spin, dye, and weave the cotton raised there. LA UNION PROVINCE occupies a narrow strip of land immediately north of the Province of Pangasinan and west of the Mountain Province. Tobacco, rice, sisal, hemp, sugar, coconuts, corn, and cotton form the most important products. At the foot of Mount Bayabas is a hot salt spring. The Manila Railroad operates lines as far as Bauang. San Fernando, the capital, may be reached either by boat or by automobile from Bauang. [Industries] ILOCOS SUR PROVINCE.--Immediately north of La Union is the Province of Ilocos Sur, a region specially adapted to the cultivation of maguey the fiber of which constitutes the principal export. But because the soil will not support the population a great many persons have turned to manufacture and trade. This has given rise to industrial specialization in different towns. Those along the coast extract salt from the sea water and export it in great quantities to inland provinces. In San Esteban, there is a quarry of stone from which mortars and grindstones are made. San Vicente, Vigan, and San Ildefonso specialize in woodworking, the first in carved wooden boxes and images and the others in household furniture. Most of the wood used in these handicrafts is imported from Abra and Cagayan. Bantay is the home of skilled silversmiths. In the other towns saddles, harness, slippers, mats, pottery, and hats are made and exported to some extent. Sisal and hemp fiber extraction and weaving of cotton cloth are common household industries throughout the province. The province embraces within its confines some of the oldest towns in the Philippines. Besides Vigan several other towns already existed in this region before the close of the sixteenth century; namely, Santa, Narvacan, Bantay, Candon, and Sinait. Just above Narvacan, on the highway which runs along the beach is an ancient watch-tower and a stretch of road bordered by a curious brick retaining wall of Spanish construction. Numerous ancient shrines are also to be seen along the Ilocos roads where the pious prayed that Heavenly favor might be shown them in their journeys.
