Immediately north of Uj^ernivik the current and bergs spread out 

 and the entire exi«anse of the surface Avaters from Upernivik to 

 Cape York, and offshore for a distance of 90 miles, partakes of a 

 slow movement toward the northwest, averaging about 5 miles per 

 day. The direction of the current is generally parallel to the coast 

 but its C(HU-se is winding and. therefore, a berg arriving at Uper-
