110 W. H. Dall—WNotes on Alaska, ete. 
The uniformity of the temperatures from top to bottom, does 
away with the idea of a sub-surface current from the Arctic 
Ocean, carrying cold water southward, a result I had expected, 
and confirmatory of my suspicions expressed in the Appendix 
to the Coast Pilot of Alaska, and of Onatzevich’s observations 
on the Kamchatka coast. 
Our current observations showed another conclusion to be 
greater than any of the Bering Sea water south of St. Law- 
rence Island. This would agree with the observations of ex- 
plorers along the Siberian coasts and elsewhere, where large 
bodies of comparatively warm water, derived from large rivers, 
are poured out over shallow areas of a cold sea basin. 
e direction of the current in the strait, when we were lying 
near the Diomedes, was reversed by the tide, and the vessel 
tailed in opposite directions during flood and ebb. The rate 
varied with the strength of the tide, and during our stay did 
not exceed three knots. The directions agreed with the trend 
able to go over the top of the island to the village on te 
other side.
