Mavor. — Bay of Fundy and Gulf of Maine 341 



With set D, 30 large 8-ounce bottles with drags attached 

 to hang at 3 fathoms, Set E, were set out. None of these 

 has been reported from the Bay of Fundy, but 4 have been 

 found outside the bay, indicating that being less affected by 

 the wind and therefore not blown on shore these bottles were 

 carried westward out of the bay by the current on the New 

 Brunswick side. 



Turning now to another series of 50 bottles, 25 small with- 

 out drags, and 25 large with drags, which were set on a line 

 NW by N from North Point, Brier Island, Nova Scotia, 

 extending for 10 nautical miles, we find that five of these had 

 been reported before the end of the year, and that they were 

 all found on the Nova Scotia coast in the Bay of Fundy 

 to the east of Brier Island, three of them reaching as far as 

 Port George near the head of the bay, a distance of 70 

 nautical miles (Fig. 4). One of these bottles, 387, was found 

 at Port George only 17 days after it was set out, giving a 

 minimum rate for the drift along the Nova Scotia shore of 

 over 4 nautical miles per day. 



To sum up, it seems clear from the calculations from Dr. 

 Dawson's tables and from the drift of bottles, that the water 

 in the Bay of Fundy has a circulation which may be de- 

 scribed as follows : Water enters the bay on its eastern side 

 and flows northeast along the coast of Nova Scotia ; it crosses 

 the bay to the New Brunswick side and flows southwestward 

 out of the bay, the bulk of the water probably passing to the 

 east of Grand Manan. The rate at which the water flows 

 is probably somewhere between 5 and 10 nautical miles per 

 day, so that the complete circuit probably takes from twenty 

 to forty days. 



A series of five hydrographic sections was made in the 

 Bay of Fundy during the summer of 1919. These sections 

 included 28 stations at which temperatures and water samples 

 were taken from the surface to the bottom at intervals vary- 

 ing from 10 meters near the surface to 50 meters at the lowest
