and 1926, which carried bottles past Cape Ann, from Ipswich Bay into Massachu- 

 setts Bay (pp. 890, 893). 



In the summers of 1922 and 1923 so many more bottles were picked up along 

 Nova Scotia than in the western side of the gulf (a difference hardly accidental, 

 because the coast line between Cape Elizabeth and Cape Cod is much frequented) 

 that the surface water was evidently moving more offshore in the western side of the 

 gulf, inshore in the eastern, than was the case in 1919. 



BOTTLES PUT OUT OFF WESTERN NOVA SCOTIA 



In 1926 the Biological Board of Canada put out four sets of bottles (each of 120) 

 off Yarmouth, Nova Scotia, in July, August, September, and October, and Dr. A. G. 

 Huntsman has contributed a summary of the recoveries in advance of his publica- 

 tion of the detailed results. 



The great majority of returns from all the sets were from the Nova Scotian side 

 of the Bay of Fundy, scattered from St. Marys Bay, at the mouth, to Minas Basin 

 and Chignecto Bay, at the head. Six others crossed to the New Brunswick shore of 

 the bay; five were picked up at Grand Manan; two went to the coast of Maine, one 

 to Cape Cod; and two went in the opposite direction, eastward, past Cape Sable to 

 Cape Negro and the vicinity of Shelburne, Nova Scotia. 



As a whole, these drifts demonstrate the northerly drift along western Nova 

 Scotia into the southern side of the Bay of Fundy, and up it. The New Brunswick 

 recoveries show the anticlockwise movement within the bay, brought out by Mavor's 

 (1923) experiments (p. 868). The drifts to Maine and Cape Cod are in hne with the 

 westerly and southerly drifts of bottles from the Mount Desert and Cape Elizabeth 

 lines. 



By what counterdrift the two bottles that went to the eastward escaped the 

 Gulf of Maine eddy and came within the influence of the Scotian eddy is not clear. 



DRIFTS OF BOTTLES ENTERING THE GULF FROM THE EASTWARD 



The northerly drift along the Nova Scotian side of the gulf to the Bay of Fundy 

 and its anticlockwise eddying continuation along the coast of Maine are further 

 illustrated by the destinations reached by a considerable number of bottles that 

 entered the gulf from lines set out off the outer coast of Nova Scotia by the Biolog- 

 ical Board of Canada in the summers of 1922, 1923, and 1924. The following data 

 have generously been contributed by Doctor Huntsman in advance of publication. 



Two bottles from a line set out southeast across the continental shelf from 

 Brazil Eock on July 17, 1922, were picked up along the western coast of Nova 

 Scotia; 8 in the Bay of Fundy; and 2 circled farther westward, 1 of them to Winter 

 Harbor and the other continuing past Mount Desert to the neighboring Long Island. 

 The localities of release were scattered from 2 to 59 miles out from Brazil Rock, 

 and none of the bottles set adrift farther out were reported from the gulf. 



The bottle that went to Long Island made so rapid a drift (45 days from release 

 to recovery) that no doubt it passed across the mouth of the Bay of Fundy. The 

 Winter Harbor bottle, with 77 days, may have entered and circled the bay.
