SUMMARV 



This cruise had three remarkable features: First, with tlte 

 exception of one berg which had melted by the lltli and another 

 located on the I7th too far to the northward and westward to ever 

 become a menace to tlie North Atlantic steamship tracks, no ice was 

 seen or reported, though temperature reports indicated that the 

 possible ice area was well covered by steamship traffic. Second, 

 the rarity of fog, with the exception of about one hour on 

 the 15th, no thick fog was encountered. Third, the current that 

 usually bears the bergs to the southward along the east slope of the 

 banks at from 0.5 to 0.7 knot per hour was negligible at this time. 



The broadcasts and reports to the Hydrographic Office and the 

 Weather Bureau were carried out as prescribed in Coast Guard 

 letter of February 4, 1924 (612-601). 



The patrol received 950 surface seawater temperature reports 

 from 160 different vessels, 24 weather, 5 ice, and 5 wreck and 

 obstruction reports. 



Special ice information was furnished to 12 vessels.
