Since I saw such use made of porcelain, I got some information respecting it, and I learned that it is made with a kind of very white earth, which is left underground for fully fifty years to refine it, so that they are in the habit of saying that the father buries it for his son. It is said that if poison is put into a vessel of fine porcelain it breaks immediately. The junks mentioned several times above are their largest vessels, and they are constructed in this manner. The lower part of the ships and the sides to a height of two spans above water-line are built of planks joined together with wooden bolts, and they are well enough put together. The upper works are made of very large canes for a counterpoise.[348] One of these junks carries as much cargo as our ships. The masts are of bamboo, and the sails of bark of trees. This island is so large that to sail round it with a prahu would require three months. It is in 5° 15′ north latitude and 176° 40′ of longitude from the line of demarcation.[349] On leaving this island we returned backwards to look for a convenient place for caulking our ships, which were leaking, and one of them, through the negligence of the pilot, struck on a shoal near an island named Bibalon;[350] but, by the help of God, we got her off. We also ran another great danger, for a sailor, in snuffing a candle, threw the lighted wick into a chest of gunpowder; but he was so quick in picking it out that the powder did not catch fire. On our way we saw four prahus. We took one laden with cocoanuts on its way to Burné; but the crew escaped to a small island, and the other three prahus escaped behind some other small islands. Between the northern cape of Burné and the island named Cimbonbon, situated in 8° 7′ N. latitude there is a very convenient port for refitting ships, and we entered it; but as we were wanting many things necessary for our work, we had to spend there forty-two days. Each one worked at one thing or another according to the best of his knowledge or ability; but our greatest labour was going to get wood in the thickets, as the ground was covered with briars and thorny shrubs, and we had no shoes.
