On the 21st April, Kruzenstern passed between the Shetland and Orkney Islands, in order to avoid the English Channel, where he might have met some French pirates, and after a good voyage he arrived at Cronstadt on the 7th August, 1806. Without taking first rank, like the expedition of Cook or that of La Perouse, Kruzenstern's trip was not without interest. We owe no great discovery to the Russian explorer, but he verified and rectified the work of his predecessors. This was in fact what most of the navigators of the nineteenth century had to do, the progress of science enabling them to complete what had been begun by others. Kruzenstern had taken with him in his voyage round the world the son of the well-known dramatic author Kotzebue. The young Otto Kotzebue, who was then a cadet, soon gained his promotion, and he was a naval lieutenant when, in 1815 the command was given to him of the _Rurik_, a new brig, with two guns, and a crew of no more than twenty-seven men, equipped at the expense of Count Romantzoff. His task was to explore the less-known parts of Oceania, and to cut a passage for his vessel across the Frozen Ocean. Kotzebue left the port of Cronstadt on the 15th July, 1815, put in first at Copenhagen and Plymouth, and after a very trying trip doubled Cape Horn, and entered the Pacific Ocean on the 22nd January, 1816. After a halt at Talcahuano, on the coast of Chili, he resumed his voyage; sighted the desert island of Salas of Gomez, on the 26th March, and steered towards Easter Island, where he hoped to meet with the same friendly reception as Cook and Perouse had done before him. The Russians had, however, hardly disembarked before they were surrounded by a crowd eager to offer them fruit and roots, by whom they were so shamelessly robbed that they were compelled to use their arms in self-defence, and to re-embark as quickly as possible to avoid the shower of stones flung at them by the natives. The only observation they had time to make during this short visit, was the overthrow of the numerous huge stone statues described, measured, and drawn, by Cook and La Perouse. On the 16th April, the Russian captain arrived at the Dog Island of Schouten, which he called Doubtful Island, to mark the difference in his estimate of its position and that attributed to it by earlier navigators. Kotzebue gives it S. lat. 44 degrees 50 minutes and W. long. 138 degrees 47 minutes. During the ensuing days were discovered the desert island of Romantzoff, so named in honour of the promoter of the expedition; Spiridoff Island, with a lagoon in the centre; the Island Oura of the Pomautou group, the Vliegen chain of islets, and the no less extended group of the Kruzenstern Islands. On the 28th April, the _Rurik_ was near the supposed site of Bauman's Islands, but not a sign of them could be seen, and it appeared probable that the group had in fact been one of those already visited.
