The Dutchmen saw many whales blowing off the coast, and in December shoals of herring rushed by, keeping up an increasing stream of life until January, when it slackened, and in March ceased. The whales made sad havoc in these shoals, gorging themselves on the small fry. These are the herring which arrive off the coast of Whang-hai, and feed on the banks and shoals during the season. The catching of them affords lucrative employment to hundreds of junks from North China. From their observations, the Dutchmen argued—one hundred and twenty years before La Perouse demonstrated the fact—that there must be a strait north of Corea, connecting with the Arctic Ocean, like that of Waigats (now called the Strait of Kara), between Nova Zemla and the island lying off the northwestern end of Russia. They thus conjectured the existence of the Straits of Tartary, west of Saghalin, before they appeared on any European map. Waigats was discovered by the Englishman, Stephen Burroughs, who had been sent out by the Muscovy company to find a northwest passage to China. Their mention of it shows that they were familiar with the progress of polar research, since it was discovered in 1556, only seven years before they left Holland. It had even at that time, however, become a famous hunting-place for whalers and herring fishers. These marine studies of the captives, coupled with the fact that they had before attempted to escape, may have aroused the suspicions of the government. In February, 1663, by orders from Seoul, they were separated and put in three different towns. Twelve went to “Saysiano,” five to Siun-schien, and five to Namman, their numbers being now reduced to twenty-two. Two of these places are easily found on the Japanese map. During all the years of their captivity, they seem not to have known anything of the Japanese at Fusan, nor the latter of them. Though thus scattered, the men were occasionally allowed to visit each other, which they did, enjoying each other’s society, sweetened with pipes and tobacco, and Hamel devoutly adds that “it was a great mercy of God that they enjoyed good health.” A new governor having been appointed over them, evidently was possessed with the idea of testing the skill of the bearded foreigners, with a view of improving the art productions of the country. He set the Dutchmen to work at moulding clay—perhaps to have some pottery and tiles after Dutch patterns, and the Delft system of illustrating the Bible at the fireplace. This was so manifestly against the national policy of making no improvements on anything, that the poor governor lost his place and suffered punishment. The spies informed on him to the king. An explosion of power took place, the ex-governor received ninety strokes on his shin-bones, and was disgraced from rank and office. The quondam improvers of the ceramic art of Corea were again set to work at pulling up grass and other menial duties about the official residence.
