It is interesting to observe that the easterly position of cyclone 

 track B on Figure 6, was due without much doubt to the presence 

 of the aforementioned anticyclone. Weather bulletins were received 

 May 5, 6, and 7, containing information that a depression was form- 

 ing in the region of Bermuda, but due to the lack of ship reports it 

 was impossible to ascertain definitely the movement of the center. 

 During the night of May 8 our barometer began to fall, which from 

 past experience indicated the approach of a storm within a radius of 

 about 500 miles. The next morning upon constructing the weather 

 map the center was revealed near Port aux Basque; it probably had 

 followed a northerly path from Bermuda as indicated on Figure 6. 

 During the next few days the weather maps indicated a tendency of

the pressure to remain relatively low to the westward, depression 

 centers being recorded from Nantucjset to Sydney. On May 11 

 a deep center appeared near Sydney and moved in a path across the 

 Gulf of St. Lawrence and out to sea. The effects of this distribu- 

 tion set up an indraft of southeasterly winds consisting of warm 

 moisture-laden air pulled across the ice regions from out in the 

 Atlantic. This condition incidently produced the longest period of 

 fog which we experienced for the season. 



The two weeks from the 13th to the 27th marked a change in the 

 previously noted tendency of the cyclones to travel consistently 

 along northeasterly tracks Where prior to this period individual 

 centers moved rapidly across the country we now saw several small 

 vortices (families) following meandering paths as if they were the
