are indebted to him for many important contributions to the 
knowledge of the natural conditions of the Behring Sea, also

of these explorers to refer to the numerous and for the most 
part accessible writings which have already been published 
regarding themd

when this is being written, the only vessel dhat has sailed from 
the Atlantic by the north to the Pacific ? As follows from the 
above narrative, this question may perhaps be answered with 
considerable certainty in the affirmative, as it may also with 
truth be maintained that no vessel has gone the opposite way
