It is my intention to leave Sweden in the beginning of July, 1878, in a steamer, specially built for navigation among ice, which will be provisioned for two years at most, and which, besides a scientific staff of four or five persons, will have on board a naval officer, a physician, and at most eighteen men--petty officers and crew, preferably volunteers, from your Royal Majesty's navy. Four walrus-hunters will also be hired in Norway. The course will be shaped at first to Matotschkin Sound, in Novaya Zemlya, where a favourable opportunity will be awaited for the passage of the Kara Sea. Afterwards the voyage will be continued to Port Dickson, at the mouth of the Yenisej, which I hope to be able to reach in the first half of August. As soon as circumstances permit, the expedition will continue its voyage from this point in the open channel which the river-water of the Obi and the Yenisej must indisputably form along the coast to Cape Chelyuskin, possibly with some short excursions towards the north-west in order to see whether any large island is to be found between the northern part of Novaya Zemlya and New Siberia. At Cape Chelyuskin the expedition will reach the only part of the proposed route which has not been traversed by some small vessel, and this place is perhaps rightly considered as that which it will be most difficult for a vessel to double during the whole north-east passage. As Prontschischev, in 1736, in small river craft built with insufficient means reached within a few minutes of this north-westernmost promontory of our vessel, equipped with all modern appliances, ought not to find insuperable difficulties in doubling this point, and if that be accomplished, we will probably have pretty open water towards Behring's Straits, which ought to be reached before the end of September.
