The fact that practically all the icebergs that drifted south of 

 Newfoundland in 1927 remained to break up on the northern part

 than ever before the processes that are continually altering the 

 movement and behavior of the water masses in this interesting area 

 around the ocean slopes of the Grand Banks. The state of the cir- 

 culation resulting from the juxtaposition of the Gulf Stream and 

 Labrador current, we have grounds to believe, is in successive months
