General note on the Bay of Fundy. — The extensive temperature observations 

 in this Bay, although taken on the surface and to a depth of 30 fathoms, did 

 not afford any definite information in regard to the direction of the current. 

 They did not give sufficiently distinct indications to enable any general move- 

 ment of the water to be traced, or to infer its continuous displacement from the 

 relative temperatures of the flood and ebb. Some interesting results were ob- 

 tained however, amongst which may be noted the effect of islands and shoals 

 in modifying the temperature of the water. This appears to result from the 

 stirring up of the water, and it causes a long trail or wake of colder water to 

 extend from islands or shoals along the line of the current. When the water 

 moves to and fro in an unbroken sheet, as it does outside the 50-fathom line, 

 where clear of obstruction, the surface temperature is more uniform, and the 

 rise in temperature with the progress of the season is more easily ascertained. 



Where the islands, and shoals are numerous, the general effect of these 

 strong currents is to chill the water in the vicinity of the coast, by mixing the 

 surface water with the colder water from below. It is possible that this lowering 

 of the surface temperature may have a bearing on the formation of fog in these 

 regions.
