Figure 12 also shows the known risks from bergs that the United 

 States-Europe steamers experienced in April, May, and June, 1928. 

 The ice-patrol broadcasts help to minimize these risks, but in times 

 of fog and darkness real safety can lie only in radically reduced ship 

 speeds and judicious caution.

From the above figures it will be seen that the total number of bergs 

 known to have been south of the forty-eighth parallel in 1928 was 

 considerably above normal during the greater part of the heavy ice 

 season. On the other hand, the number of bergs to drift south of the 

 forty-third parallel was distinctly subnormal. Some of the latter 

 bergs got into the circulation southeast of the Tail of the Grand 

 Banks, however, and attained extremely low latitudes before melting. 



Field ice was distinctly below normal in amount about the Grand 

 Banks as well as inshore to the westward. Its southerly extension was 

 never great and it disappeared from the picture relatively early.
