Fig. 6 Facsimile of Berkh's map of 1823 (see bibliography) showing the route of Bering's first expedition from Okhotsk to Bering Strait and return. Mean meridional 

 scale, 1:16,000,000 (original 1:9,000,000). The dates have been identified and added from Berkh's abridged version of midshipman Peter Chaplin's log book. On sea they represent 

 noon positions. Berkh's plotting of the ship's tracks has been slightly modified for August 18-20 and August 29, 1728. It would also seem as if the position of the tracks on August 

 10, 1728 (Bering's report implies that a landing was made on St. Lawrence Island, cf. p. 18) and June 10-17. 1729 (Chaplin's log book) might be susceptible of other interpre- 

 tation. But otherwise, so far as known, Berkh's map is the standard, and only modern, reconstruction of the tracks of Bering's vessels on his first expedition. It does for that 

 ?xpedition what Captain Bertholf's map (PI. I) does for the second. 



The vessels in which the several sections of the tracks shown were sailed are: August 22-September, 1727, Fortune (Bering and Spanberg) and nameless vessel (Chirikov and 

 -haplin; it is this vessel's track that is shown); July 15-September 1. 1728, St. Gabriel; June 6-July 3, 1729, St. Gabriel; July 14-23, 1729. St. Gabriel.
