from its western side recurving to the left across the mouth of the bay. Flotsam 

 drifting in this branch may then come under the influence of the drift setting east- 

 ward into the right-hand side of the Grand Manan Channel. But only one bottle 

 can so be classified, while five seem to have passed by the channel in their rounds to 

 Penobscot Bay. 



It is interesting that only two bottles from any of the several series" have been 

 recovered along the coast sector between Petit Manan and the western entrance to 

 the Grand Manan Channel, although many must have passed by. Judging from 

 this, such parts of the dominant surface drift as veers westward past Grand Manan

 tude of Mount Desert Island. 



The circulatory scheme just outlined reconciles the bottle drifts for 1923 with 

 those of the bottles set out in the Bay of Fundy in the summer of 1919, except that 

 the latter certainly hugged the coast more closely in their westward and southward 

 journey, else so many of them would hardly have been embayed behind Cape Cod. 

 In this respect the summer of 1919 paralleled the April and July currents of 1925 



SI One set out in the Bay of Fundy in August, 1919 (Mavor, 1922, bottle no. 181); the other (no. 65) from the inner part of 

 the Cape Elizabeth line of July, 1922.
