1664 and 1668. A whaling captain, WILLEM DE VLAMINGH, sailed in 1664 round the northern extremity of Novaya Zemlya to Barents' winter quarters, and thence eastwards, where one of his men thought he saw land ("Jelmert-landt," _Witsen_, p. 902).[147] The same Vlamingh says that in 1668 he discovered, twenty-five miles N.N.E. of Kolgujev, a new island three to four miles in circumference. This island, which was described in great detail, and named by the discoverer "Witsen's Island," has not since been seen again (_Witsen_, p. 923). 1666. In this year some vessels were sent from the Netherlands to the north-east. There were Jews among the owners, and the seafarers were furnished with letters in Hebrew, because it was believed that they would come in contact with some of the lost tribes of Israel. Nothing farther appears to have been known of the voyage, which undoubtedly was without result. (_Witsen_, p. 962.) [Illustration: DE LA MARTINIERE'S MAP. ] 1675. A Dutch whaling captain, CORNELIS PIERSZ. SNOB-BERGER, visited Novaya Zemlya, on whose coast he killed three whales and six hundred walruses. He would probably have got still more "fish," if he had not in 72-1/2 deg. found an ore, which appeared to contain silver, gold, and other metals. Instead of blubber the skipper now loaded ore, which in his opinion was precious, but afterwards on being tested at home was found to be valueless (_Witsen_, p. 918). 17th Century, year not stated. Shipmaster CORNELIS ROULE is said to have sailed in the longitude of Novaya Zemlya to 84-1/2 deg. or 85 deg. N.L. and there discovered a fjord-land, along which he sailed ten miles. Beyond that a large open sea was seen. From a high mountain situated on a sound, in which he rode, it appeared that he might sail one or two watches further to the north. He found there large numbers of birds, which were exceedingly tame (_Witsen_, p. 920). If we take some degrees from the latitude stated, which is perhaps not very unreasonable in dealing with the narratives of old whalers, which have passed through two or three hands, Roule may, as far back as two hundred years ago, have reached Franz-Josef's Land, and sailed along its coast to a very high latitude for those regions.
