Of much greater importance were Captain-lieutenant (afterwards Admiral Count) LUeTKE's voyages to Novaya Zemlya in the summers of 1821, 1822, 1823, and 1824, voyages conducted with special skill and scientific insight. The narrative of them form one of the richest sources of our knowledge of this part of the Polar Sea. But as he did not penetrate in any direction farther than his predecessors, an account of these voyages does not enter into the plan of the historical part of this work. Among Russian journeys the following may be noticed:-- Those of the mate IVANOV in 1822-28, during which he surveyed the coast between the Kara river and the Petchora by overland travelling in Samoyed sleighs. PACHTUSSOV'S voyages in 1832-35.[166] W. BRANDT, merchant, and KLOKOV, chief of the civil service, at Archangel, sent out in 1832 an expedition with very comprehensive aims from that town, for the purpose of re-establishing the sea-route to the Yenisej, of surveying the east coast of Novaya Zemlya, and of walrus-hunting there. Three vessels were employed, viz., a "carbasse" manned by ten men, including the Commander-lieutenant in the corps of mates Pachtussov, who in previous voyages with Ivanov had become well acquainted with land and people along the coasts of the Polar Sea;[167] the schooner _Yenisej_ under Lieutenat KROTOV with ten men; and a hunting _lodja_ commanded by the hunting mate GWOSDAREV. Pachtussov was to undertake the east coast of Novaya Zemlya, Krotov to sail through Matotschkin Sound and across the Kara Sea to the Yenisej, and Gwosdarev to carry on hunting in order to cover part of the costs of the expedition.
