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 miles 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 Bay of Fundy (Mavor’s 
lines D and G) partook of this drift (curiously enough, however, none from the inter- 
mediate line). 
Mavor (1922, p. 118) has emphasized the uniform time intervals of 7 of the 11 
bottles that were picked up in Massachusetts Bay 73 to 80 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 along 
this sector of the coast line.
