 REPORT OF FLEET-CAPTAIN BERING ON HIS EXPEDITION TO THE EASTERN COAST OF SIBERIA. 
 To the most Serene Sovereign, the high and powerful, the Empress of all the Russia.: 
 A short relation of the Siberian Expedition upon which (I) was sent. 
 Of your Imperial Majesty the most humble servant and fleetcaptain, W.I.Bering. 
 On February 5 of the late year 1725 I received from her Imperial Majesty the Empress Ekaterina Alexievna, of happy and well-deserving memory, the autographic instructions of his Imperial Majesty Peter the Great, of happy and well-deserving memory, a copy 
 of which is hereunto affixed. 
 Instructions. 
 (1.) There should be built on the Kamchatka [River], or at some other place adjacent, one or two boats with decks. 
 (2.) With these boats [you are directed] to sail along the coast which extends northwards and which is supposed (since no one knows the end of it) to be continouous with America. 
 (3.) And therefore [you are directed] to seek the point where it connects with America and to go to some settlement under European rule, or if any European vessel is seen, learn of it what the coast visited is called, which should be taken down in writing, an authentic account prepared, placed on the chart and brought back here.
