First edition. Sauer was secretary to the Billings' expedition, in which Sarychev also participated (his separate account was published in Russian in the same year). Billings sailed to the Behring Strait, touching land both on the Chukchi peninsular and in Alaska. Most importantly, the expedition explored the Aleutian islands. The present account, which complements Sarychev's, was compiled by Sauer from official reports.
