870 BUIXETIN OF THE BUREAU OF FISHERIES 



These bottle drifts justify Mayor's (1922) general conclusion that in the summer 

 of 1919 the water was drifting in along the southern side of the bay, circling north- 

 ward across to the New Brunswick shore about abreast of St. John, setting west and 

 southwest along New Brunswick and out of the bay past the southern side of Grand 

 Manan. This, as he points out (1922, p. 116), is entirely consistent with the domi- 

 nant set resulting from Dawson's current measurements; more consistant, indeed, 

 than one might have expected of observations of these two sorts taken several years 

 apart in such tide-swept waters. 



The drift westward along New Brunswick, according to Mavor's analysis, was 

 at a rate of at least 5 nautical miles per day. This, with the rates for the bottles 

 that drifted inward along the Nova Scotian shore (p. 868) , suggests a general daily 

 rate of 4 to 5 mUes for the periphery of the Bay of Fundy eddy. 



Fifteen of the bottles set out in the Bay of Fundy in 1919 were picked up out- 

 side the bay in the Gulf of Maine — 2 from the June series and 13 from the August 

 series. The two June bottles, however, represent a much larger percentage than do 

 the August recoveries; for only 10 bottles were set out in June, and these were the 

 only ones picked up, whereas 220 were set out in August, most of the recoveries 

 coming from within the Bay of Fundy. None of the September bottles (75 in 

 number) were picked up in the Gulf of Maine. 



The two June bottles were put out, respectively, 14 and 18 miles south of Grand 

 Manan on the 18th. One was picked up at Bailey's Mistake (a cove on the north 

 shore of the Grand Manan Channel) about midway of its length; the other was 

 recovered in Penobscot Bay. Both of these bottles undoubtedly passed out of the 

 bay in the outflowing current along the south side of Grand Manan; but the one 

 circled Grand Manan, to be caught up in the indraft demonstrated by current 

 measurements for the Grand Manan Channel; while the other, put out only 4 miles 

 farther south, escaped this eddy and traveled westward along the coast of Maine. 

 There is every reason to suppose that the 13 August bottles also went out of the Bay 

 of Fundy along the south side of Grand Manan, for they show very uniform drifts. 

 One was returned from Jonesport, Me., one from Schoodic Head, near Mount 

 Desert, and all the rest from the Massachusetts Bay region and Cape Cod. Bottles 

 from the innermost as well as from the outermost lines in the Ba}^ of Fundy (Mavor's 

 lines D and G) partook of this drift (curiouslyenough, however, none from the inter- 

 mediate line). 



Mavor (1922, p. 118) has emphasized the vmiform time intervals of 7 of the 11 

 bottles that were picked up in Massachusetts Bay 73 to SO days after being put out. 

 This, with the fact that so large a proportion of all the bottles picked up outside the 

 Bay of Fundy within four months after being set adrift were found along so short a 

 stretch of the coast line, is evidence enough of a very definite surface drift from the 

 northeastern to the southwestern side of the gulf during the late summer and early 

 autumn of 1919; and the recovery of two bottles on the eastern coast of Maine 

 makes it probable that this line of drift lay rather close in to the shore as far as the 

 mouth of Penobscot Bay. However, since none were found between Penobscot Bay 

 and Cape Ann they seem to have followed tracks farther out from the land alons 

 this sector of the coast line.
