large numbers for these jars during his time, and that they were willing to spend great sums for them. Apparently work on these jars continued in the North, possibly among the unconquered Igorots, for De Morga had no knowledge of such current production. Later, the knowledge may have again trickled down to Vigan, where a flourishing industry of Burnay jar manufacture survives to this day. Although the Japanese described very high quality jars coming from the Philippines, not all were of elegant nature. In fact, De Morga had some disdain for some of the jars that the Japanese were buying, so they could have been similar to the well-known balanga and other jars in use today. These jars are generally handed down as heirlooms and are noted for their qualities in enhancing the fermentation process. Possibly one of the Japanese uses for the Rusun jars was fermentation of products like Kombucha and Umeboshi plums. For instance, a Japanese family in rural Japan stated that their family used old Rusun jars for exactly this purpose up to this day. In 2009, Japanese and Filipino archaeologists from the Sumitomo Foundation-funded Boljoon Archaeological Project conducted by the University of San Carlos with the National Museum of the Philippines, discovered ancient Japanese pottery that has been to believed to been in existence since the early 1700's. The ancient Japanese pottery that was discovered there, has proven that there was activity of trading activity between Japan and Cebu Island Philippines going back to the 16th century. Fishing technologies The Filipinos were skilled in all types of fishing and fisheries. In the south, the basnig, a Viking-like ship, was and is the vessel of choice among the Bisayans for ocean fishing. The salambao is a type of raft that utilizes a large fishing net which is lowered into the water via a type of lever made of two criss-crossed poles. Night fishing was accomplished with the help of candles similar to the copal of Mexico. These candles were made from a particular type of resin. Fish corrals, like the ones still used today, were also employed by the ancient Filipino. However, the area in which the Filipino most astonished Westerners was in their advanced aquaculture: Many have looked to Japan for an explanation for these advanced methods. The roe was transplanted to safe pens for incubation and to guard the small fry from predators. Only when
