It is unfortunate that no observations were taken in the Bay of Fundy in April. 

 1920; lacking such, it is impossible to state whether or not this expansion of water of 

 high salinity involved the bay. In 1917 an alteration of the opposite sort took place 

 there from February to April, evidence that the iucorporation of fresher water from 

 above was more than sufficient to counteract the effect of any indraft at the bottom. 



A cross-section of the Eastern Channel for April (stations 20106 to 20108) 

 would reproduce the March picture (fig. 99) so closely that it need not be reproduced 



Fig. 114.— Vertical distribution of salinity in the northeastern corner of the gulf. A, March 22, 1920 (station 20081); B, 

 April 12, 1920 (station 20100); C, May 10, 1915 (station 10273); D, June 10, 1915 (station 10233); E, August 12, 1914 (sta-

here. The only difference worth comment is that the whole column of water on 

 Browns Bank had become vertically equalized during the interval at a salinity (32.7 

 per mille) about equaling the mean of the corresponding stratum over the channel, 

 evidence that no important overflow had taken place over the bottom of the bank 

 meantime, either from the west or from the east. The distribution of salinity in the 

 trough of the channel also points to a slackening of the inflow along the bottom
