2. The southern extremity of the Labrador Cuirent increases 

 quickly in size and extends around the Tail of the Bank the first 

 part of ^farch. 



3. The Labrador Current is present around the bank the entire 

 ice season, but during that time is subject to periodic variations. 



4. During the season the Labrador Current floods the northern 

 part of the bank, spreads in over its eastern slope, and encroaches 

 on tlic southern part of the bank on the bottom. 



5. The boundary of the two currents, Labrador and Gulf Stream, 

 on the east side of the Great Bank is variable and difficult to deter- 

 mine, due to excessive interdigitation of the two waters. 



6. The Gulf Stream is characterized by a variable undulated 

 northern boundary west of the Tail, which moves in closer to the 

 slopes of the Grand Banks of Newfoundland during summer and 

 autumn. Just east of the Tail of the Bank the Gulf Stream turns 

 sharply in swirling form to the north. 



7. Banks water possesses a striking identity, which is of a promi- 

 nent character except where temporary encroachments occur on its 

 northern, eastern, and southern sides. 



8. There is no southwest stream flow of the Labrador Current 

 across the Great Bank. 



9. The Labrador Current, upon meeting the Gulf Stream, does not 

 dive beneath the latter, but turns sharply, between parallels 42 and 

 43 and meridians 51 and 52, to flow easterly, parallel with the 

 Gulf Stream.
