In 1864, the year that Elling Carlsen found the navigation so open that he passed the Northern Gate and sailed round Spitsbergen, Nordenskiöld, at the head of a small expedition, was at work in Ice Fjord, and, unable to go north on account of the ice, rounded South Cape, entered Stor Fjord, visited Edge's Land and Barents Land, and from the summit of White Mountain, near Unicorn Bay, rediscovered the west coast of the island reported by Edge two hundred and fifty years before. In 1868, as leader of the Swedish North Polar Expedition in the _Sofia_, he reached 81° 42´, in 17° 30´ east, the highest latitude then reached by a steam vessel, and his farthest north; his next Polar venture, four years afterwards, in the _Polhem_, ending in his having to winter in Mossel Bay, where his generous endeavour to feed one hundred and one extra men, who were ice-bound, on provisions intended for his own twenty-four, would have ended in disaster had he not been relieved by Leigh Smith in the _Diana_. The _Diana_ was the steam yacht built for James Lamont, in which, like Leigh Smith, he cruised for several seasons in the Arctic seas, combining sport with exploration in a truly admirable way. To these two yachtsmen we owe much of our knowledge of Spitsbergen, Novaya Zemlya, and Franz Josef Land, but we can only give them passing mention here. We must, however, find room for Lamont's useful find of the coal mine in Advent Bay, from which he filled up the _Diana's_ bunkers. "When I paid a visit to the coal mine," he says, "I found it quite a busy scene for a quiet Arctic shore. The engineer and fireman directed the blasting, my English hands quarried, while the Norwegians carried the sacks down the hill. The old mate, the many-sidedness of whose character I have so much valued on my various voyages, was digging away with the rest, though I am sorry that in the sketch his weather-beaten face is turned away. All the rest are portraits, and the reader will notice that Arctic work is not done in the attractive uniforms known to Cowes and Ryde. The coal-bed was about three feet thick, and lay very horizontally between two layers of soft, mud-coloured limestone. It was harder to obtain than I anticipated, because saturated, through all the cracks and interstices, with water which had frozen into ice more difficult to break through than the coal itself, thereby rendering these fissures worse than useless in quarrying. This is tertiary coal, and is of fair quality, but contains a good deal of sulphur. When we began to burn it, so much water and ice was unavoidably mixed with it that the engineers had to let it drain on deck in the hot sun and then mix it with an equal bulk of Scotch coal. Consumed in this way the ten tons obtained in three days was a useful addition to the fast-dwindling stock on board."
