Nansen water-bottle. A full description of both this water-bottle and the reversing 

 thermometers may be fotmd in the section on hydrographic work in the report on the 

 '* Investigation of the Bays of the Southern Coast of New Brunswick with a view to 

 Their Use for Oyster Culture."^ 



The temperatures read on the Richter thermometer were all corrected for the 

 expansion of the mercury column at the temperature at which the reading was made, 

 and the corrected figures were recorded in the tables and used in constructing the 

 temperature curves. All temperatures are in the centigrade scale. 



The densities and salinities of the water samples were determined by W. H. 

 Chase, but as he was called away by military duties, he was unfortunately prevented 

 from completing the work.^ Such discrepancies between density and salinity in many 

 cases were found in the records that it was considered necessary to repeat the analysis 

 of the samples, and Professor Vachon of Laval University was so kind as to do this 

 during the summer of 1916. Unfortunately, Prof. Vachon found that the water sam- 

 ples must have altered by evaporation since they were collected, and it has accord- 

 ingly been regretfully decided not to publish the data for the Bay of Fundy stations, 

 but to confine this report to the temperature observations. The densities, salinities 

 and chlorine contents of the samples from St. Mary bay, as determined by W. H. 

 Chase, will be found in table III at the end of the report. 



LOCATION OF OBSERVATION STATIONS. 



The positions of all the stations are indicated on the accompanying map, on 

 which the fifty and hundred fathom lines have also been inserted, giving an idea of 

 the conformation of the bottom of the Bay. The stations were located so as to give 

 as complete sections as possible, showing the conditions existing in the various parts 

 of the water. In making the observations, the stations were found by the use of a log. 



Stations I to IV are on a straight line drawn from East Quoddy Head, Campo- 

 bello island, to Boar's Head, Petit Passage, Long island, as follows: — 



station 1 7 miles from East Quoddy Head.

The remaining Bay of Fundy stations are located as follows : — 



station V 22 miles N.W. from Digby Gut.

 2 The responsibility for the planning of the work, selecting the stations, etc., rests with 

 E. Home Craigie, as does also the recording and working up of the temperature data, while 

 observations on density and salinity were in charge of W. H. Chase. The two workers colla- 

 borated on the draft of the earlier part of this report, and on the preparation of the accom- 

 panying map and some of the figures. Owing to Mr. Chase's departure for the front, it has 

 been necessary to complete the report without his assistance or criticism.
