The same year several other walrus-hunters also made remarkable voyages in the Kara Sea. Captain E.A. ULVE first sailed along the west coast of Novaya Zemlya to 76 deg. 47' N.L., then back to Matotschkin Schar, through which he passed on the 7th and 8th August into the Kara Sea, which was completely free of ice, with the exception of some few very scattered pieces. After sailing backwards and forwards in different directions in the Kara Sea, he returned through the Kara Port on the 24th August. Captain F.E. MACK made a similar voyage. He sailed from the 28th June to the 8th July northwards along the west coast of Novaya Zemlya, which was free of ice between the Petchora and the Admiralty peninsula, where fast ice was found, and fourteen sailing vessels and two steamers were now assembled. On the 8th and 9th June thunder was heard here. From the Admiralty peninsula Mack sailed again, first to the south, and then, on the 18th July, through Matotschkin Sound into the Kara Sea, which was nearly free of ice. Captain P. QUALE, again, and A.O. NEDREVAAG, sailing master, penetrated through Yugor Sound into the Kara Sea, and sailed there to 75 deg. 22' N.L., and 74 deg. 35' E.L. (Greenwich).[177] Also in 1871 a number of walrus-hunters made remarkable voyages in the Kara Sea. Of these, however, only one, Mack, in the schooner _Pole Star_, penetrated eastwards farther than all his predecessors. On the 14th June he sailed into the Kara Sea through the Kara Port, but found the sea still covered with continuous fast ice, from 1.8 to 2 metres in thickness. He therefore turned and sailed northwards along the west coast of Novaya Zemlya to the Gulf Stream Islands (76 deg. 10' N.L.), where he remained till the 3rd of August. The temperature of the air rose here to +10.5 deg.. The name, which the Norwegian walrus-hunters have given these islands, owes its origin to the large number of objects from southern seas which the Gulf Stream carries with it thither, as floats from the Norwegian fisheries, with their owner's marks frequently recognisable by the walrus-hunters--beans of _Entada gigalobium_ from the West Indies, pumice-stone from Iceland, fragments of wrecked vessels, &c. On the 3rd of August Mack passed the northernmost promontory of Novaya Zemlya. Hence he sailed into the Kara Sea, where at first he fell in with ice. Farther on, however, the ice disappeared completely, and Mack on the 12th of September reached 75 deg. 25' N.L. and 82 deg. 30' E.L. (Greenwich) according to Petermann, but 81 deg. 11' Long, according to the _Tromsoe Stiftstidende_. He returned through Yugor Schar, which was passed on the 26th September.[178] The same year E. Johannesen, after long endeavouring without success to make his way into the Kara Sea through the southern strait, sailed northwards along the west coast of Novaya Zemlya, and did not leave Cape Nassau until the 15th October.
