First and only edition in English of the Englishman Sauer's full account of the Billings voyage, on which he travelled as secretary to the Captain: the classic description of the Aleutian Islands. This was the last of the major Russian surveys of the eastern coast of Siberia, and accomplished a great deal of geographical research. They visited Kodiak, Montague Island and Prince William Sound, and saw Mount St. Elias.

Billings's naval career had started under Cook: he sailed as an able-bodied seaman on the Discovery, transferring on Cook's death to the Resolution. His voyage included a revisiting of Kamchatka where Captain Clerke, who had taken over the command of the third voyage after Cook's death, had been buried. One of the plates in this publication shows Clerke's grave.

Sauer's is the "first account in English of the first major exploring expedition sent out by the Russians to the Frozen Ocean and the North Pacific after Bering's second expedition of 1741... The chart was made by Arrowsmith from Sauer's notes and Captain Billings's astronomical observations..." (Streeter). The large folding map is of Bering's Strait and the American and Asian coasts. The appendices include linguistic tables, one of which compares Kamchatkan, Aleutian and Kodiak dialects.
